Description

Back lining device

The present invention relates to a lining apparatus suitable for producing puree by passing various strained ingredients (for example, vegetables, fruits, cereals, etc.) heated and softened by superheated steam through a strainer.

Among the present applicants, Nepure Co., Ltd. previously described various ingredients (for example, vegetables, etc.) that have been heat-softened for a short time (for example, 30 to 240 seconds) in an atmosphere of superheated steam (for example, 120 to 500 ° C. superheated steam). A novel puree manufacturing method has been proposed in which puree is manufactured by passing a strainer (also referred to as “screen”) through a strainer (also referred to as “screen”) (see Patent Document 1).

According to this new puree manufacturing method, the food is softened by heating in high temperature superheated steam for a short time and in almost oxygen-free state prior to the back-tanning process, so that the food is boiled for a long time prior to the back-tanning process. Unlike ordinary purees that are heat-softened by heating, oxidation and cell destruction of the food during the heat-softening treatment can be suppressed as much as possible. Since the puree that is finally obtained is left intact without destroying the cell membrane and is less altered by oxidation, the original color, aroma, and taste of the food In addition to maintaining the nutritional value as it is, depending on the food, there are additional effects that are specific (immunity stimulating effect, immune balance suppressing effect, tea Nutritional enhancement effect, soybean nutritional value enhancement effect) also have the advantage of a obtained (see Patent Documents 2-5).

By the way, conventionally, as a lining device used in such a puree manufacturing method, a plurality of cylindrical containers that revolve around an inclined rotation axis while revolving around a vertical revolution axis have a smaller diameter than the same container. A conventional bottomed cylindrical strainer is disposed, and the softened food placed in the bottomed cylindrical strainer is pressed against the peripheral wall of the cylindrical strainer by the combined centrifugal force of revolution and rotation, and is turned over. The apparatus (see Patent Documents 1 and 6), the top inlets of the same cylindrical container are combined into one, and each bottom outlet is communicated with the annular product receiving part, so that the softened food can be continuously fed into the container from the top part. 2. Description of the Related Art A second conventional device (see Patent Document 7) that can discharge filtrate (pure) and residue separately and continuously from the bottom while feeding is known.

In general, as a device for continuously separating a solid and a liquid from a solid-liquid mixed raw material in which a solid and a liquid are mixed, a conical concave strainer (screen) is placed with the concave surface upward. By rotating around a vertical central axis, the liquid material passes (permeates) through the inclined surface of the strainer due to centrifugal force, while the solid content rises along the conical inclined surface of the strainer due to centrifugal force. A third conventional device (Patent Document 8) is known that overflows from the peripheral edge (shakes off by centrifugal force).

Further, in the field of milling machines, a lower mill having a conical convex rubbing surface and an upper mill having a conical concave rubbing surface are coaxially opposed to each other and rotated relatively to each other. There is known a fourth conventional apparatus (Patent Document 9) in which grains are crushed in the gap.

JP 2009-178168 A International Publication 2009/154051 Pamphlet International Publication 2011/016432 Pamphlet JP 2011-217461 A JP 2011-217642 A JP 2001-299191 A JP 2010-179265 A JP 2003-071322 A JP 2009-248072 A

According to the first and second conventional devices, since the device was originally designed for the purpose of crushing and mixing multiple ingredients, it may be suitable for the manufacture of puree mixed with multiple ingredients, but maintains revolution. However, in order to continuously supply the softened food and discharge the filtrate and residue to the container that rotates while rotating, a complicated supply / discharge mechanism must be adopted, and the apparatus must be expensive. I don't get it. In addition, since the food pressing force required to pass through the strainer depends on the complex synthetic centrifugal force of revolution and rotation, the adjustment of the food pressing force is due to the change in the number of rotations of both rotation and revolution. It is not always easy to obtain the optimum food pressing force necessary for passing through the strainer according to the properties (density, hardness, size, fiber content, moisture content, etc.) of the food.

According to the third conventional apparatus, the liquid component passes through the strainer by centrifugal force, while the solid component rises along the conical inclined surface of the strainer by centrifugal force and overflows from the peripheral edge of the upper end. Therefore, the present invention is intended to be relatively effective for a solid-liquid mixed raw material in which the solid content and the liquid content are clearly separated or the liquid content is sufficiently larger than the solid content. Like a food that has been softened by superheated steam, it is not necessarily suitable for use in solid-liquid separation from a solid-liquid mixed raw material in which the solid component and the liquid component have a relatively strong bond or are not clearly separated.

According to the fourth conventional apparatus, the lower die having a conical convex rubbing surface and the upper die having a conical concave rubbing surface are arranged coaxially opposite to each other while rotating them relatively, It is understood that the grain is crushed in the gap, but its use is limited to milling dry granules such as grain, and the application to the use for solid-liquid separation from solid-liquid mixed raw materials is also described. In addition, the concave-convex relationship between the lower die and the upper die may be reversed, and it must be said that there is a binding inhibition factor with the third conventional device.

The present invention was devised in view of the above-described technical background. The object of the present invention is to provide various foods (for example, vegetables, fruits, grains, etc.) that have been heat-softened with superheated steam as cells (cell membranes). ) Is prevented from passing through the strainer as much as possible, and a strainer is passed through the strainer to provide a backing device suitable for continuously producing puree that retains the original color, aroma, taste and nutritional value of the ingredients. It is in.

Another object of the present invention is that the original color, aroma, taste, etc. of the food, regardless of the nature of the softened food (density, hardness, viscosity, size, fiber / seed / skin content, moisture content, etc.) An object of the present invention is to provide a lining apparatus capable of producing puree with its nutritional value maintained as it is with high quality.

Another object of the present invention is to provide a backing apparatus that has a simple structure, is easy to maintain, can be manufactured at low cost, and has a relatively small installation area.

Further other objects and operational effects of the present invention should be easily understood by those skilled in the art by referring to the following description of the specification.

[Basic configuration]
It is considered that the above technical problem can be solved by a backing apparatus having the following basic configuration. That is, this lining device includes a strainer member supported with a conical concave surface (including a frustoconical concave surface) serving as a filtration surface facing upward, and a conical convex surface (including a frustoconical convex surface serving as a pressing surface). And a holding member supported in a state of facing down.

The strainer member and the hold member are arranged such that the conical concave surface and the conical convex surface are aligned with each other so that the conical center axes are aligned coaxially and face each other with a gap therebetween. At least one of the member and the hold member is configured to rotate in one direction or both directions around the conical central axis by power.

The lining device further supplies a raw material food material (for example, a softened food material by superheated steam) to the gap between the conical concave surface of the strainer member and the conical convex surface of the hold member. When the passage, the strainer member, and the hold member rotate with the raw material food sandwiched therebetween, a filtrate collection unit that collects a filtrate passing through the conical concave surface of the strainer member, and the strainer member, A residue collecting part that collects a residue that rises along the conical concave surface and overflows from the peripheral edge of the upper end when the hold member rotates with the softened food sandwiched therebetween.

[Effects of basic configuration]
According to the lining apparatus having such a configuration, since the pressing surface of the holding member exists on the front side of the filtration surface of the strainer member that contributes to the solid-liquid separation action with a gap therebetween, If the raw material to be supplied is, for example, a softened food that has been treated with superheated steam, the liquid content is extracted by gradually grinding between the two surfaces with the relative rotation of the filtration surface and the pressing surface. The softened food material that has been squeezed out and thus extracted or squeezed out of the liquid is filtered through the conical concave surface due to the solid-liquid separation action of the conical concave surface serving as the filtration surface. Residues (solid matter such as fibers, skins, seeds, etc.) overflow from the upper peripheral edge of the conical concave surface and are continuously collected in the residue collecting part.

The liquid (pure) obtained in this way is generated by passing through the strainer member while gently disintegrating the softened food by the grinding action between the filtration surface of the strainer member and the pressing surface of the hold member. As a result, the majority of cells are left intact without destroying the cell membrane, and there is little alteration due to oxidation, so the original color, aroma, taste, and nutritional value of the food are retained, and some foods are unique. Additional effects (immunostimulation effect, immune balance suppression effect, tea leaf nutritional value enhancement effect, soybean nutritional value enhancement effect) are also obtained.

Further, the rubbing mode between the filtration surface and the pressing surface that contributes to the grinding of the softened food can be easily adjusted by speed controlling the power for rotating the strainer member and / or the hold member. By selecting the most suitable rubbing mode by speed control (speed magnitude, periodic fluctuation of speed, intermittent rotation, etc.), the properties of softening ingredients (density, hardness, viscosity, size, fiber / seed / skin) It is possible to produce a puree with the original color, aroma, taste, and nutritional value as it is, regardless of the content ratio, moisture content, etc.

Furthermore, while continuously supplying the raw material ingredients and discharging the filtrate and residue, the basic structure is that the strainer member and the hold member are arranged vertically opposite to each other, and at least one of them can be rotated. It can be manufactured at low cost because it is simple, and maintenance such as disassembly and cleaning is easy. In addition, it is basically a vertical structure centered on the vertical axis. There are advantages such as a relatively small area.

[Additional functions for basic configuration]
In the above basic configuration, a configuration is added in which the gap between the conical concave surface of the strainer member and the conical convex surface of the hold member is expanded and reduced by power while maintaining the rotation. Also good.

The grinding action of the raw material ingredients between the filtration surface of the strainer member and the pressing surface of the hold member depends on the pressure contact force between the raw material ingredients and the filtration surface or the pressing surface. It also varies depending on the size of the gap and the degree of raw material filling in the gap.

However, if the structure that the gap between the conical concave surface of the strainer member and the conical convex surface of the hold member is expanded and reduced while maintaining the rotation is added, the above-mentioned raw material pressure contact force can be easily obtained. For example, the initial gap is set wide, and after the raw materials are sufficiently filled, the gap is controlled to be gradually narrowed by power, or the gap is cycled. Depending on the nature of the ingredients (density, hardness, size, fiber / seed / skin content, moisture content, etc.) Can be optimized.

[Embodiment of basic configuration and additional functions]
In the above basic configuration, the following three embodiments exist as to which of the strainer member and the hold member is rotated.

The first embodiment is configured such that only the strainer member of the strainer member and the hold member is rotated in one direction or both directions around the central axis of the cone by power. is there. At this time, with respect to the additional function, the gap between the conical concave surface of the strainer member and the conical convex surface of the hold member is expanded and contracted by power while maintaining the rotation of the strainer member. It will be constituted as follows.

According to such a configuration, the raw material food supplied to the gap between the conical concave surface of the strainer member and the conical convex surface of the hold member is rotated on the conical concave surface of the strainer member, and thus centrifugal force is applied. At the same time, by rubbing and crushing (grinding) with the conical convex surface, a solid-liquid mixed material sufficiently containing liquid to be extracted or squeezed out is generated, and the strainer member having the conical concave surface is fixed. It is used for liquid separation. Therefore, this 1st embodiment becomes a thing suitable for the fringing process of a raw material foodstuff with comparatively much liquid content, or solid content and liquid content having isolate | separated clearly.

In addition, when the above-described additional function exists, the gap between the conical concave surface of the strainer member and the conical convex surface of the hold member is expanded and contracted by power while maintaining the rotation of the strainer member. For example, the initial gap is set to be wide, and after the raw material is sufficiently filled, the gap is controlled to be gradually narrowed by power, or the gap is periodically widened and narrowed. By controlling the gap, etc., it is possible to optimize the rubbing action of the raw material regardless of the properties of the raw material (density, hardness, size, fiber / seed / skin content, moisture content, etc.) it can.

Needless to say, the degree of grinding action, solid-liquid separation action, and strainer washing action of the raw material can be adjusted optimally by appropriately controlling the rotation direction and / or rotation speed of the strainer member.

According to a second embodiment, of the strainer member and the hold member, only the hold member is configured to rotate in one direction or both directions around the conical center axis by power. Become. At this time, with respect to the additional function, the gap between the conical concave surface of the strainer member and the conical convex surface of the hold member is expanded or contracted by power while maintaining the rotation of the hold member. It will be constituted as follows.

According to such a structure, the raw material food supplied between the conical concave surface of the strainer member and the conical convex surface of the hold member rotates integrally with or along with the conical convex surface of the hold member. The solid-liquid mixed material containing the liquid component to be extracted or squeezed at the same time is in contact with the conical convex surface of the holding member or integrally with the conical concave surface. As a result, centrifugal force is applied and the strainer member having a conical concave surface is subjected to the solid-liquid separation action. Therefore, this 2nd embodiment becomes a thing suitable for the fringing process of the raw material food which has comparatively little liquid content, or solid content and the liquid component are not isolate | separated clearly.

In addition, when the above-mentioned additional function exists, the gap between the conical concave surface of the strainer member and the conical convex surface of the hold member is expanded and contracted by power while maintaining the rotation of the hold member. For example, the initial gap is set to be wide, and after the raw material is sufficiently filled, the gap is controlled to be gradually narrowed by power, or the gap is periodically widened and narrowed. By controlling the gap, etc., it is possible to optimize the rubbing action of the raw material regardless of the properties of the raw material (density, hardness, size, fiber / seed / skin content, moisture content, etc.) it can.

Needless to say, if the rotation direction and / or rotation speed of the holding member is appropriately controlled, the degree of rubbing / disintegration (grinding) action, solid-liquid separation action, gap cleaning action, etc. of the raw material can be adjusted optimally. That is.

In the third embodiment, both the strainer member and the hold member are configured to rotate in one direction or both directions around the conical center axis by power. At this time, with respect to the additional function, the gap between the conical concave surface of the strainer member and the conical convex surface of the hold member is maintained by the power while maintaining the rotation of the strainer member and the hold member. It is configured to expand and contract.

According to such a configuration, by rotating only one of the strainer member and the hold member, it is possible to obtain the same operational effects as the first and second embodiments, and in addition, the strainer member By individually controlling the rotation modes while rotating both the holding member and the holding member, it is possible to obtain special effects that cannot be achieved from the first and second embodiments.

In addition, when the above-described additional function exists, the gap between the conical concave surface of the strainer member and the conical convex surface of the hold member is expanded and increased by power while maintaining the rotation of the strainer member and the hold member. For example, the initial gap is set wide, and after the raw material ingredients are sufficiently filled, the gap is controlled to be gradually narrowed by power, or the gap is periodically changed. Optimize the fretting action of raw ingredients regardless of the nature of the ingredients (density, hardness, size, fiber / seed / skin content, moisture content, etc.) can do.

In particular, according to the third embodiment, “single-phase operation” in which only the strainer member or only the hold member is rotated, and “in-phase operation” in which the strainer member and the hold member are rotated in the same direction at the same or different speeds. , “Reverse phase operation” in which the strainer member and the hold member are rotated in the opposite directions at the same or different speeds, “differential operation” in which the strainer member and the hold member are rotated so that the speed difference between them is constant, In each of the single phase operation, the in-phase operation, the reverse phase operation, and the differential operation, “vibration operation” in which rotation is performed so that the speed difference between the two may vibrate can be appropriately selected and implemented.

Therefore, for example, the strainer member is maintained at a constant speed optimum for the solid-liquid separation action, and the hold member is kept at a constant speed so that the speed difference with the strainer member is an optimum value for the grinding action. Adopt “in-phase operation”, or adopt “reverse phase operation” in which the speed of the strainer member and the hold member is relatively low, but the difference in speed between them is high. `` Differential operation '' in which the speed of the strainer member fluctuates so that the solid-liquid separation action fluctuates while maintaining the speed difference between the strainer member and the hold member constant so that the action itself is constant. Adopting “vibration operation” in which the speed difference between the strainer member and the holding member is vibrated to promote the grinding and / or solid-liquid separation. Or, further, as said to promote a milling 砕作 and solid-liquid separation action by combining "gap increase and decrease operation", it is possible to realize various efficient operation.

[Embodiment of raw material supply passage]
As for the raw material supply passage, any embodiment is adopted as long as it can efficiently supply, for example, food softened with superheated steam to the gap between the filtration surface of the strainer member and the pressing surface of the hold member. can do. However, considering that the strainer member and / or hold member is a rotating body (non-stationary object), some route-selective consideration is required for the raw material supply passage. In addition, considering the fact that the entire filtering surface of the strainer member and the entire pressing surface of the hold member are effectively utilized to exert the grinding action and the solid-liquid separation action, the outlet of the raw material supply passage is Such positioning considerations are required.

In one embodiment, the softened food supply passage is configured to vertically penetrate the hold member and includes a single or a plurality of outlet holes that open to the conical convex surface. Is done.

According to such a configuration, since the raw material supply passage communicates vertically, gravity can be used to supply the raw material, and one or more outlet holes thereof are opened in a conical convex surface. Therefore, the raw material is efficiently supplied from right above to one or more appropriate locations in the gap between the filtration surface of the strainer member and the pressing surface of the hold member.

In another embodiment, the conical convex surface of the holding member has a food for distributing the softened food discharged from each of the single or a plurality of outlet holes in the radial direction in the gap. A guide groove is formed.

According to such a configuration, the softened food discharged from each of the outlet holes moves in the food guide groove and is distributed quickly and over a wide area almost in the radial direction. While maintaining the gap between the filtration surface and the pressing surface of the holding member in a narrow width suitable for the grinding operation, the raw material ingredients are distributed over a wide range over the entire length in the radial direction. The separation action can be realized efficiently.

At this time, if at least one of the single outlet hole or the plurality of outlet holes is arranged at a central position of the conical axis or a position in the vicinity of the conical axis, a large number of radial holes are provided over the entire length in the radial direction. Even without providing an outlet hole, in combination with the action of the food guide groove, the raw material food can be distributed over a wide range over almost the entire length in the radial direction, and the food guide groove is linearly outward in the radial direction. Or if it is extended in the shape of a vortex, a foodstuff can be smoothly moved in a guide groove using a centrifugal force.

In addition, if the holding member is a solid member having the conical convex surface (for example, an aluminum die-cast product, Muku's stainless steel product, etc.), the holding member has a pressing surface necessary for the grinding action. Therefore, by forming a tunnel penetrating through the inside, a raw material food supply passage can be realized, and there is no need to separately provide a pipe material as the raw material supply passage.

In another embodiment, the strainer member is composed of an inverted conical plate having a large number of filtration through holes on its slope.

According to such a configuration, by properly selecting the thickness of the inverted conical plate body and the number and arrangement of the filtration through holes, the solid-liquid separation action is maintained while maintaining the rigidity necessary for the grinding action. It is possible to realize the optimum filtration function necessary for the operation. At this time, if cut and raised pieces are formed corresponding to the rotation direction on the inlet side of the filtration through-hole, the raw material ingredients are caught by these cut and raised pieces, and the grinding action is promoted. Moreover, the through-hole passing action of the liquid can be promoted. Further, if the filtration through hole has a tapered inner wall having a large diameter on the inlet side and a small diameter on the outlet side, the filtration efficiency is improved due to the improved gripping force of the softened food and the reduced permeation resistance. Can be made.

In another embodiment, at least one of the conical convex surface of the hold member and the conical concave surface of the strainer member has a radial groove.

According to such a configuration, the improvement of the gripping force of the softened food and the rectifying effect of the softened food can be combined to increase the grinding effect of the softened food and improve the filtration efficiency.

In another embodiment, a horizontal annular portion and a vertical annular auxiliary strainer portion are connected to the periphery of the upper end of the conical concave surface of the strainer member.

According to such a configuration, the softened food supplied to the gap between the hold member and the strainer member is not only the filtration through-hole disposed on the inclined surface of the strainer member, but also the filtration disposed in the annular auxiliary strainer portion. Liquid extraction is performed also by the through-hole for use, so that liquid extraction efficiency is further improved. At this time, if a scraper portion for scraping off residues accumulated on the horizontal annular portion is provided at the upper end periphery of the conical convex surface of the hold member, the relative relationship between the hold member and the strainer member Utilizing rotation, the accumulated residue can be efficiently discharged.

According to the present invention, since the pressing surface of the hold member exists on the front side of the filtration surface of the strainer member that contributes to the solid-liquid separation action, there is a pressing surface of the hold member. For example, in the case of a softened food that has been treated with superheated steam, the liquid content is extracted or squeezed out by being gradually ground between the two surfaces as the filtration surface and the pressing surface rotate relative to each other. In the softened food material containing the squeezed liquid component, the liquid component (pure) passes through the conical concave surface and returns to the filtrate collection part due to the solid-liquid separation action of the conical concave surface serving as the filtration surface. Solids such as fibers, skins, and seeds) overflow from the upper peripheral edge of the conical concave surface and are continuously collected in the residue collecting part.

Further, the rubbing mode between the filtration surface and the pressing surface that contributes to the grinding of the softened food can be easily adjusted by speed controlling the power for rotating the strainer member and / or the hold member. By selecting the most suitable rubbing mode by speed control (speed magnitude, periodic fluctuation of speed, intermittent rotation, etc.), the properties of softening ingredients (density, hardness, size, fiber, seed, skin, etc.) Regardless of the content rate, moisture content rate, etc., it is possible to produce a puree with the original color, fragrance, taste, and nutritional value intact as it is.

Hereinafter, several preferred embodiments of a backing apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

[First Embodiment]
A first embodiment of a backing apparatus according to the present invention will be described with reference to FIGS. In the first embodiment, both the strainer member and the hold member can be rotated in both forward and reverse directions (for example, −2000 rotations / minute to +2000 rotations / minute), and the strainer member filtration surface and the hold member The gap with the pressing surface can also be increased or decreased while maintaining the rotation.

As can be seen from these drawings, the lining apparatus 10A has a lining process section 2 supported by the gantry 1 at an appropriate height. As best shown in FIGS. 1 and 3, the tanning processing unit 2 includes a strainer member 201 supported with a conical concave surface serving as a filtration surface facing upward, and a conical convex surface serving as a pressing surface. And hold member 204 supported downward.

As shown in FIG. 4, in this example, the strainer member 201 is an obtuse truncated cone having a flat central region 201 b, an inclined surface 201 c that occupies almost the whole, and a flat narrow flange-like peripheral portion 201 e. A plurality of filtration through holes 201d along each of a plurality of radial straight lines on the inclined surface 201c. By providing light at intervals, a function as a filtration surface having sufficient rigidity is provided.

As shown in FIG. 5, in this example, the holding member 204 is a metal solid body (for example, aluminum die-casting) whose upper surface 204g is flat and whose bottom surface 204a serving as a pressing surface is a conical convex surface. Product, stainless steel product, etc.), one inlet hole 204e is opened at the center of the top surface, and three outlet holes 204b are opened at equal intervals in the circumferential direction near the center of the bottom surface 204a. At the same time, a passage for the raw material that branches into three is formed inside so as to communicate between one inlet hole 204e and three outlet holes 204b. As a result, a function as a pressing surface having sufficient rigidity is provided, and an integral molding of the food supply passage branching from one inlet hole 204e to three outlet holes 204b is realized. In addition, since the food supply passage branched into a plurality of parts in this way has the effect of sucking the food by the action of centrifugal force along with the rotation of the holding member 204, there is also an advantage that the supply of food can be smoothly performed.

Each of the three outlet holes 204b is connected to a starting end of a food guide groove 204c extending outward in the radial direction in a spiral shape or an arc shape, and each terminal end of the three food guide grooves 204c is a peripheral edge. It extends to reach the vicinity of the portion 204d. Reference numeral 204d denotes a narrow flange-shaped peripheral edge extending horizontally.

3 again, the strainer member 201 is fixed in a horizontal posture to the upper end portion of the vertical shaft 202 that is rotatably supported via the bearing 203. As a result, the strainer member 201 is rotatably supported with the conical concave surface serving as the filtration surface facing upward. On the other hand, in the holding member 204, the supply pipe 205 and the inlet hole 204e communicate with a lower end portion of a vertical raw material supply pipe 205 that is rotatably supported by a bearing 206 fixed to the elevator 301. In this way, it is fixed in a horizontal posture. As a result, the hold member 204 is rotatably supported with the conical convex surface serving as the pressing surface facing downward. In addition, the strainer member 201 and the hold member 204 are positioned so that the conical concave surface and the conical convex surface are vertically aligned with a conical center axis aligned with a gap therebetween.

The shaft 202 of the strainer member 201 is rotationally driven via the rotational drive system 4. The rotational drive system 4 includes a first servo motor 401 capable of forward and reverse rotation at an arbitrary speed, a driven pulley 403 fixed to the shaft 202, and an unillustrated fixed to the output shaft of the first servo motor 401. The timing belt 402 is wound around a driving pulley and a driven pulley 403. On the other hand, the raw material supply pipe 205 connected to the hold member 204 is rotationally driven via the rotational drive system 5. The rotational drive system 5 is fixed to the second servomotor 501 capable of forward and reverse rotation at an arbitrary speed, the driven pulley 504 fixed to the material supply pipe 205, and the output shaft of the second servomotor 501. The timing belt 503 is wound between the driving pulley 502 and the driven pulley 504. As a result, both the strainer member 201 and the hold member 204 are configured to be capable of rotating at an arbitrary speed in both directions around the conical center axis by power.

As shown in FIG. 1, the lifting platform 301 that supports the bearing 206 is inserted in the guide sleeves 303 arranged at the four corners thereof through the vertical guide rods 302, thereby maintaining the horizontal posture in the arrow A. As shown, it is supported so that it can be raised and lowered. The lifting platform 301 is driven up and down via the lifting drive system 6. The elevating drive system 6 includes a third servo motor 602 fixed to the support base 304 via a fixture 601, a ball screw shaft 603 that converts the rotational motion of the third servo motor 602 into a vertical linear motion, Consists of Thereby, the gap between the conical concave surface of the strainer member 201 and the conical convex surface of the hold member 204 can be expanded and reduced by power while maintaining the rotation of the strainer member 201 and the hold member 204. Yes.

This lining device 10A has a raw material supply passage for supplying raw material food (for example, softened food by superheated steam) R to the gap between the conical concave surface of the strainer member 201 and the conical convex surface of the hold member 204. . In this example, the raw material supply passage refers to a series of passages from the inlet hole 204e of the holding member 204 to the three outlet holes 204b after passing through the raw material supply pipe 205 (FIG. 3, see FIG.

Further, the straining device 10A further collects the filtered material Q that collects the filtered material Q that passes (permeates) through the conical concave surface of the strainer member 201 when the strainer member 201 and the holding member 204 rotate with the raw material ingredient R interposed therebetween. When the collection tank 207, the strainer member 201, and the hold member 204 rotate with the raw material ingredient R interposed therebetween, the residue collection tank that collects the residue P that rises along the conical concave surface and overflows from the upper edge rim 201e. 208.

As shown in FIG. 3, in this example, the filtrate collection tank 207 has an inner bottom surface 207 b that surrounds the entire lower surface of the strainer member 201 and tilts downward as viewed from the front. The inner bottom surface is configured to be continuous with the filtrate discharge pipe 207a. Therefore, by setting an appropriate container just below the tip of the filtrate discharge pipe 207a, the produced filtrate (pure) can be continuously taken out and stored.

As shown in FIGS. 1 and 3, in this example, the residue collection tank 208 collects the residue P released to the outside by a centrifugal force from the gap between the strainer member 201 and the hold member 204. At the same time, it consists of two storage tanks that can be divided so that the filtrate collection tank 207 is sandwiched from the left and right. The inner bottom surface 208b of each of the left and right storage tanks is inclined down to the left for the left storage tank and to the right for the right storage tank, and a residue discharge port 208a is provided at the inclined lower end. Therefore, by setting an appropriate container directly under each of the left and right residue discharge ports 208a, the generated residues (solid matter such as seeds, skins, fibers, etc.) can be continuously taken out and stored. it can.

According to the lining apparatus 10A having the above configuration, since the pressing surface of the holding member 204 exists with a gap on the front side of the filtration surface of the strainer member 201 that contributes to the solid-liquid separation action, the raw material ingredients The raw material ingredient R supplied to the gap between the supply pipe 205, the inlet hole 204e of the hold member 204, and the three outlet holes 204b in this order is, for example, softened ingredients (softened fruits, softened vegetables, etc.) that have been superheated with steam. ), The contained liquid component is extracted or squeezed out by being gradually ground between the two surfaces with the relative rotation of the filtration surface and the pressing surface, and thus the extracted or squeezed liquid component. The softened food material containing the solids and liquids of the conical concave surface 204a serving as the filtration surface allows the filtrate Q (pure) Q to permeate the conical concave surface 201a and return to the filtrate collection tank 208 and the residue (fiber, skin). , Seeds etc. Form thereof) P, respectively are continuously collected by overflow from the upper peripheral portion 201e of the conical concave 201a to residual 瑳捕 collection tank 208.

The filtrate (pure) Q obtained in this way is generated by passing through the strainer member 201 while gently disintegrating the softened food by the grinding action between the filtration surface of the strainer member 201 and the pressing surface of the hold member 204. Because most of the cells are left intact without destroying the cell membrane, and there is little alteration due to oxidation, the original color, aroma, taste, and nutritional value of the ingredients are preserved. Depending on the food, specific additional effects (immunity activation effect, immune balance suppression effect, tea leaf nutrition value enhancement effect, soybean nutrition value enhancement effect) can also be obtained.

Further, the rubbing mode between the filtration surface and the pressing surface, which contributes to the grinding of the softened food material, controls the speed of the power for rotating the strainer member 201 and / or the hold member 204 via the

servo motors

401 and 501. Therefore, it is possible to easily adjust the properties of the softened food (density, hardness, etc.) by always selecting the most suitable rubbing mode by speed control of the rotational power (speed magnitude, periodic fluctuation of speed, intermittent rotation, etc.). To produce high quality puree that retains its original color, aroma, taste, and nutritional value, regardless of viscosity, size, fiber / seed / skin content, etc. Is possible.

In addition, while continuously supplying the raw material ingredient R and discharging the filtrate Q and the residue P, the basic structure is that the strainer member 201 and the hold member 204 are arranged to face each other in the vertical direction, and at least Since it is simple enough to allow one to rotate, it can be manufactured at low cost, and maintenance such as disassembly and cleaning is easy. In addition, it is basically a vertical structure centered on the vertical axis. Therefore, there are advantages such as a relatively small installation area.

In addition, since the gap between the conical concave surface 201a of the strainer member 201 and the conical convex surface 204a of the hold member 204 can be expanded and reduced by power while maintaining rotation, for example, the initial gap is widened. After the raw material is sufficiently filled, the raw material is controlled by dynamic control such as gradually narrowing the gap with power or periodically changing the gap widely by power. Regardless of the properties (density, hardness, size, fiber / seed / skin content, moisture content, etc.), the rubbing action of the raw material can be optimized.

In particular, according to the first embodiment, “single-phase operation” in which only the strainer member 201 or only the hold member 204 is rotated, and the strainer member 201 and the hold member 204 are rotated in the same direction at the same or different speeds. “In-phase operation”, strainer member 201 and hold 204 member are rotated in opposite directions at the same or different speed, “reverse phase operation”, strainer member 201 and hold member 204 are rotated so that the speed difference between them is constant. “Differential operation”, “Single-phase, In-phase, Reverse-phase, or Differential operation”, and “Vibration operation” in which the speed difference between the two is vibrated is selected as appropriate. be able to.

For this reason, for example, the strainer member 201 is maintained at a constant speed optimum for the solid-liquid separation action, and the hold member 204 is kept at a constant speed so that the speed difference with the strainer member is an optimum value for the grinding action. “Same-phase operation” is used, or the speed of the strainer member 201 and the hold member 204 is relatively low, but the “reverse-phase operation” is said to be high for the speed difference between the two. Or, the speed of the strainer member fluctuates so that the solid-liquid separation action fluctuates while the speed difference between the strainer member and the hold member is kept constant so that the grinding action itself is constant. The speed difference between the strainer member 201 and the hold member 204 so as to adopt the “dynamic operation” or to promote the grinding action and / or the solid-liquid separation action. Realize various efficient operations, such as adopting "vibration operation" that says to vibrate, and further promoting grinding action and solid-liquid separation action by combining "gap increase / decrease operation" Can do.

[Second Embodiment]
A second embodiment of the backing apparatus according to the present invention will be described with reference to FIGS. In the second embodiment, the strainer member can be rotated in both forward and reverse directions, but the hold member cannot be rotated (fixed), and the gap between the two is also stopped and manually changed. Is possible, but dynamic change while maintaining rotation is impossible (fixed). Note that the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

As can be seen from these drawings, the backside apparatus 10B has a backside processing unit 2 supported at an appropriate height by the gantry 1. The tanning processing unit 2 includes a strainer member 201 supported with a conical concave surface serving as a filtration surface facing upward, and a hold member 204 supported with a conical convex surface serving as a pressing surface facing downward. Is included.

As shown in FIG. 7, even in this example, the strainer member 201 has an obtuse angle cone having a flat circular central region 201b, an inclined surface 201a that occupies almost the whole, and a flat narrow flange-like peripheral portion 201e. It consists of a trapezoidal metal plate (for example, aluminum plate, stainless steel plate, etc.), and a plurality of filtration through holes 201d are provided on the inclined surface along each of a plurality of radial straight lines. By providing light at intervals, a function as a filtration surface having sufficient rigidity is provided.

As shown in FIG. 8, even in this example, the hold member 204 is a metal solid body (for example, aluminum die-cast) in which the upper surface 204g is flat and the bottom surface 204a serving as the pressing surface is a conical convex surface. Products, stainless steel products made by cutting, etc.), one entrance hole 204e is located slightly eccentric from the center of the top surface, and one near the center of the bottom surface 204a, which is just below it. An outlet hole 204b is provided, and a vertical passage for a raw material to communicate between one inlet hole 204e and one outlet hole 204b is formed in the outlet hole 204b. As a result, a function as a pressing surface having sufficient rigidity is provided, and a food material supply passage extending vertically from one inlet hole 204e to one outlet hole 204b is realized by integral molding or integral processing. .

One outlet hole 204b is connected to the starting end of a food guide groove 204c that spirals outward in the radial direction, and the end of the spiral food guide groove 204c reaches the vicinity of the peripheral edge. It has been extended.

Again, referring back to FIG. 6, the strainer member 201 is fixed in a horizontal posture to an upper end portion of a vertical shaft 202 that is rotatably supported via a bearing 203. As a result, the strainer member 201 is rotatably supported with the conical concave surface serving as the filtration surface facing upward. On the other hand, the hold member 204 is fixed in a horizontal posture to a lower end portion of a vertical support rod 209 supported by being suspended from a support portion (not shown). As a result, the hold member 204 is supported in a non-rotatable (fixed) state with the conical convex surface serving as the pressing surface facing downward. In addition, the strainer member 201 and the hold member 204 are positioned so that the conical concave surface and the conical convex surface are vertically aligned with a conical center axis aligned with a gap therebetween.

The shaft 202 of the strainer member 201 is rotationally driven via the rotational drive system 7. The rotary drive system 7 includes a first servo motor 701 capable of forward and reverse rotation at an arbitrary speed, a driven pulley 704 fixed to the shaft 202, and a drive pulley fixed to the output shaft of the first servo motor 701. 702 and a timing belt 703 wound around a driven pulley 704. As a result, the strainer member 201 is configured to be able to rotate at an arbitrary speed around the conical center axis line by power while the hold member 204 is fixed.

Even in the lining apparatus 10B of the second embodiment, the raw material food (for example, the softened food by superheated steam) is supplied to the gap between the conical concave surface of the strainer member 201 and the conical convex surface of the hold member 204. However, in this example, since the holding member 204 is always in a stationary state, a plurality of inlet holes 204e can be provided, or a food material to be connected to the inlet hole 204e can be supplied. As in the first embodiment, the pipe does not need to be vertically plumbed along the conical center axis in consideration of the rotation of the holding member, and can be piped by any path, and the inlet hole 204e. And the food supply line may be completely connected.

Although illustration is omitted, when the strainer member 201 and the hold member 204 rotate with the raw material ingredients sandwiched between them, a filtrate collection tank for collecting the filtrate that passes through the conical concave surface of the strainer member 201, and a strainer Including a residue collection tank that collects the residue P that rises along the conical concave surface and overflows from the upper edge rim 201e when the member 201 and the hold member 204 rotate while sandwiching the raw material ingredients. Of course.

According to the lining device 10B having such a configuration, the raw material to be supplied to the gap between the conical concave surface of the strainer member 201 and the conical convex surface of the hold member 204 rotates on the conical concave surface of the strainer member 201. In this way, centrifugal force is applied, and at the same time, it is rubbed with the conical convex surface to collapse (milling), thereby producing a solid-liquid mixed material sufficiently containing the liquid to be extracted or squeezed out. The strainer member 201 having a concave surface is used for solid-liquid separation.

Therefore, according to the backing apparatus 10B of the second embodiment, although the structure is simple and can be manufactured at a low price, the liquid content is relatively large or the solid content and the liquid content are clearly separated. It becomes a thing suitable for the tanning processing of a raw material ingredient.

[Third Embodiment]
With reference to FIGS. 9 to 11, a third embodiment of the back-lining apparatus according to the present invention will be described. In this third embodiment, the hold member can be rotated in both forward and reverse directions, but the strainer member cannot be rotated (fixed), and the gap between the two is also stopped and manually changed. Is possible, but dynamic change while maintaining rotation is impossible (fixed). Note that the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

As can be seen from these drawings, the lining apparatus 10 </ b> C has a lining processing section supported on the base 71. This tanning processing unit includes a strainer member 201 supported with a conical concave surface serving as a filtration surface facing upward, and a hold member 204 supported with a conical convex surface serving as a pressing surface facing downward. Include. The basic structure of the strainer member 201 and the hold member 204 can be the same as that of the first embodiment.

The strainer member 201 is fixed in a horizontal posture to the upper end portion of the support column 209 with the conical concave surface serving as a filtration surface facing upward. On the other hand, a bearing 211 is fixed to the tip of a cantilevered support arm 210 that protrudes horizontally from the vertical support wall 72, and the food supply pipe 205 rotates while maintaining a vertical posture. Supported as possible. The food supply pipe 205 is connected and fixed to an inlet hole provided at the center of the upper surface of the hold member 204. As a result, the hold member 204 is suspended and supported rotatably via the food supply pipe 205 while maintaining a horizontal posture. The strainer member 201 and the holding member 204 are positioned such that the conical concave surface and the conical convex surface are aligned vertically with the conical center axis line aligned with each other with a gap therebetween.

The raw material supply pipe 205 is supported at its upper portion by a bearing provided at the tip of a cantilevered support arm 213 that protrudes horizontally from the support wall 72, and its upper end is expanded in diameter so that the raw material food is supplied. The receiving port 212 is used.

The hold member 204 is rotationally driven via a predetermined rotational drive system 8. The rotational drive system 8 includes a servomotor 801 disposed at the base of the support arm 210 and capable of forward and reverse rotation at an arbitrary speed, a driven pulley 803 fixed to the material supply pipe 205, and an output of the servomotor 801. It comprises a timing belt 804 wound around a driving pulley 802 and a driven pulley 803 fixed to the shaft. As a result, the hold member 201 is configured to be capable of rotating at an arbitrary speed around the conical center axis line by power while the strainer member 201 is fixed.

Even in the lining apparatus 10C of the third embodiment, raw material food (for example, softened food by superheated steam) is supplied to the gap between the conical concave surface of the strainer member 201 and the conical convex surface of the hold member 204. It has a raw material supply path. This raw material supply passage passes through the raw material supply inlet 212 through the raw material supply pipe 205, and then passes from the inlet hole at the center of the upper surface of the hold member 204 through the inside of the hold member 204 to the outlet hole at the bottom of the hold member 204. It becomes a series of passages leading to.

Further, the back-lining device 10C includes a filtrate collection tank 207 that collects filtrate that passes through the conical concave surface of the strainer member 201 when the strainer member 201 and the hold member 204 rotate with the raw material sandwiched therebetween. When the strainer member 201 and the hold member 204 rotate with the raw material ingredient R sandwiched therebetween, a residue collection tank 208 is provided for collecting the residue P that rises along the conical concave surface and overflows from the upper edge 201e. It is done. The filtrate Q collected in the filtrate collection tank 207 is discharged to the outside from the filtrate discharge pipe 207a.

Even in the lining device 10C having such a configuration, the raw material food supplied between the conical concave surface of the strainer member 201 and the conical convex surface of the hold member 204 comes into contact with the conical convex surface of the hold member 204. However, the solid-liquid mixed material containing the liquid component extracted or squeezed together with the conical convex surface of the hold member 204 is crushed by the conical concave surface by being integrated or rotated together with this. Centrifugal force is applied by being rotated together with or while being in contact with each other, so that the strainer member having a conical concave surface is subjected to the solid-liquid separation action. Therefore, this 3rd embodiment becomes a thing suitable for the fringing process of the raw material food which has comparatively little liquid content, or solid content and the liquid component are not isolate | separated clearly.

[Various variations]
As shown in FIG. 12, the specific form of the raw material guide groove is not limited to one in which one vortex-shaped food guide groove 204c is extended from each of the single or plural outlet holes 204b. As shown in FIG. 13, a plurality of linear guide grooves 204c may be extended radially from a single outlet hole located at the center.

As a specific form of the filtration through-hole, as shown in FIG. 14, the filtration through-hole 201f having a cut-and-raised piece formed on the inlet side corresponding to the rotational direction is used. When the raw material is caught on the piece, the grinding action is promoted and the liquid passage through action may be promoted.

Further, as shown in FIGS. 15 and 16, as the filtration through hole 201d, the inner wall of the hole is tapered so that the inlet side opening has a large diameter and the outlet side opening has a small diameter. Also good. That is, as shown in FIG. 15 (a), the filtration through-hole 201d has a large diameter on the inlet side opening that opens to the conical concave surface 201a, and as shown in FIG. The outlet side opening that opens in the convex bottom surface has a small diameter. Therefore, as shown in FIG. 16, the inner wall of each filtration through hole 201d is tapered.

According to the filtration through hole 201d having such a tapered inner wall, the passage resistance of the outlet side opening is extremely small even if the inner diameter of the outlet side opening is set to the minimum diameter necessary for permeation of the filtrate. In addition, there is an advantage that the filtration efficiency of the softened food is improved because the squeezing effect is added in the process of moving from the inlet side opening to the outlet side opening. There is an advantage that it is easy to be caught or bitten, and as a result, the grinding action of the food is also promoted.

In this example, the tapered inner wall is configured to be continuous from the inlet-side opening to the outlet-side opening. However, due to hole processing problems, the tapered inner wall over the entire length of the hole is used. When machining is difficult, from the entrance side opening to just before the exit side opening, a tapered inner wall whose inner diameter gradually decreases, leaving a cylindrical inner wall with a relatively small diameter as before. May be. Even with such a tapered inner wall, it was confirmed that a sufficient effect was obtained as compared with the case where the entire length of the hole was equal.

The structure of the drive system is not limited to the belt drive system, and a gear drive system and other known drive systems can be arbitrarily adopted, and the drive system and the drive source are not associated one-to-one, as appropriate. By adopting an appropriate speed change or power distribution mechanism, one drive source may correspond to a plurality of drive systems.

On the conical convex surface and / or conical concave surface of the holding member 201, if necessary, radial straight or vortex-shaped ridges or spatters to promote grinding of raw material ingredients or discharge of residue Protrusions, rounded protrusions, wavy irregularities, etc. may be provided.

An example of a holding member having a radial groove on a conical convex surface is shown in FIGS. As shown in the figure, the conical convex surface 204a of the holding member 204A is divided into a large number of narrow regions extending radially, and in the narrow regions, every other one adjacent to each other in the circumferential direction. By cutting the width region shallowly into a cross-sectional elliptical arc shape (see FIG. 22), a large number of radially extending grooves 204j are formed, and a region sandwiched by these radial grooves 204j is a flat surface. For this reason, the conical convex surface 204a of the hold member 204A has a structure in which the concave and convex portions are continuous in the circumferential direction because the radial grooves 204j and the radial flat surfaces are alternately present in the circumferential direction. For example, the hold member 204A can be used in combination with the strainer member 201 having a flat conical concave surface shown in FIG.

That is, according to the hold member 204A having such a concavo-convex structure on the conical convex surface 204a, the conical convex surface 204a of the hold member and the conical concave surface of the strainer member via the inlet hole 204e and the three outlet holes 204b. The softened food material introduced into the gap with 201a is further distributed to the radial grooves 204j almost uniformly by centrifugal force while being guided and moved by the food material guide grooves 204c, and radially outward along each radial groove 204j. While being transported in the direction, the conical convex surface 204a and the conical concave surface 201a (see FIG. 4) are subjected to a grinding process to extract a liquid component from the food, and are used for the solid-liquid separation action of the strainer member. It will be. At this time, each radial groove 204j not only guides the softened food outward in the radial direction but also restricts the movement of the softened food in the circumferential direction to some extent, so that the conical convex surface 204a and the conical concave surface There exists an advantage which accelerates | stimulates the grinding action by relative rotation with 201a.

An example of a strainer member having a radial groove on a conical concave surface is shown in FIGS. As shown in the figure, the conical concave surface 201a of the strainer member 201A is partitioned into a large number of narrow regions extending radially, and in the narrow regions, every other narrow adjacent one in the circumferential direction. By cutting the width region shallowly into a cross-sectional elliptical arc, a large number of radially extending grooves 201f are formed, and the region sandwiched by these radial grooves 201f is a flat surface 201g (see FIG. 22). Therefore, the conical concave surface 201a of the strainer member 201A has a structure in which the concave and convex portions continue in the circumferential direction because the radial grooves 201f and the radial flat surface 201g are alternately present in the circumferential direction. (See FIG. 21). This strainer member 201A can be used, for example, in combination with a holding member 204 having a flat conical convex surface shown in FIG.

That is, according to the strainer member 201A having such a concavo-convex structure on the conical concave surface 201a, the conical convex surface 204a (see FIG. 5) of the hold member and the strainer via the inlet hole 204e and the three outlet holes 204b. The softened food material introduced into the gap with the conical concave surface 201a of the member is further distributed to the radial grooves 201f almost uniformly by centrifugal force while being guided and moved by the food material guide grooves 204c. Along the radial direction, the conical convex surface 204a and the conical concave surface 201a are subjected to a grinding process by the relative rotation to extract a liquid component from the food material, which is used for the solid-liquid separation action of the strainer member. It will be. At this time, each radial groove 201f not only guides the softened food material outward in the radial direction, but also restricts the movement of the softened food material in the circumferential direction to some extent, so that the conical convex surface 204a and the conical concave surface 201a There is an advantage of promoting the grinding action by the relative rotation of.

In the above description, the holding member with radial grooves (204A in FIG. 17) and the strainer member without radial grooves (201 in FIG. 4) are used in combination, and the holding member without radial grooves (204 in FIG. 5). And a radial grooved strainer member (201A in FIG. 19), but of course, a radial grooved hold member (204A in FIG. 17) and a radial grooved strainer member (201A in FIG. 19) Needless to say, the combined use is more effective.

Next, a further improved combination of the holding member 204B and the strainer member 201B will be described with reference to FIGS.
A hold member 204B having a scraper portion on the outer periphery of the upper edge of the conical convex surface will be described with reference to FIGS. In these drawings, the same components as those in FIGS. 17 and 18 are denoted by the same reference numerals, and description thereof is omitted. As shown in FIGS. 23B and 23C, in the hold member 204B, scraper portions 204k are arranged at four positions at 90 ° intervals on the outer periphery of the upper edge portion of the conical convex surface 204a. The scraper unit 204k is configured to scoop up and remove or scrape a residue described later when the relative rotation with the strainer unit 201B is performed by an inclined surface facing the rotation direction.

A strainer member 201B having an annular auxiliary strainer portion on the upper outer periphery of the conical recess will be described with reference to FIGS. 25 and 26. FIG. In these drawings, the same components as those in FIGS. 19 and 20 are denoted by the same reference numerals and description thereof is omitted. In FIGS. 25 and 26, it should be noted that the filtration through holes arranged on the inclined surface 201c are not shown in order to avoid complication of the drawings. As shown in FIGS. 25A and 25B, in this strainer member 201B, an annular auxiliary strainer portion 201i is provided on the upper outer periphery of the conical recess 201a. As shown in FIG. 27, the annular auxiliary strainer portion 201i is composed of an annular vertical wall provided so as to surround the upper edge portion of the conical inclined surface 201c, and a large number of filtration through holes 201d are arranged in this. Thus, it is designed to function as an auxiliary strainer. An annular horizontal portion 201h is provided between the annular auxiliary strainer portion 201i and the conical inclined surface 201c. As will be described later, the annular horizontal portion 201h is configured to deposit residues discharged by the solid-liquid separation action of the conical concave surface 201a.

The state where the hold member 204B and the strainer member 201B are assembled is shown in FIGS. As is clear from these drawings, when the holding member 204B is coaxially stacked on the strainer member 201B with an appropriate gap therebetween, for example, when both are rotated so that a relative speed difference is generated in the same direction, As described above, the softened food supplied to the gap between the conical convex surface 204a of the holding member 204B and the conical concave surface 201a of the strainer member 201B has a relative speed difference between the conical convex surface 204a and the conical concave surface 201a. The liquid component is extracted or squeezed out from the softened food. The liquid component thus obtained is taken out to the outside through the filtration through hole 201d arranged on the inclined surface 201c of the strainer member 201B. On the other hand, the residue that still contains some liquid is lifted along the inclined surface 201c of the strainer member 201B due to centrifugal force, and finally discharged onto the annular horizontal portion 201h from the upper peripheral edge of the strainer member 201a. (See FIG. 27). The residue containing the liquid discharged on the annular horizontal portion 201h is further deposited on the inner peripheral surface of the annular auxiliary strainer portion 201i and pressed against the inner peripheral surface of the annular auxiliary strainer portion 201i by centrifugal force. Thus, the liquid content contained in the residue is discharged to the outside through a large number of filtration through holes 201d arranged in the annular auxiliary strainer portion 201i. On the other hand, the residue deposited on the annular horizontal portion 201h is periodically lifted up by the four scraper portions 204k disposed on the outer periphery of the upper portion of the hold member 204B, and moves over the annular auxiliary strainer portion 201i to the outside. Will be released.

Therefore, according to the combined use of the hold member 204B and the strainer member 201B having this novel structure, the softened food supplied to the gap between the hold member 204B and the strainer member 201B is disposed on the inclined surface 201c of the strainer member. The liquid extraction is performed not only by the filtration through hole 201d but also by the filtration through hole 201di disposed in the annular auxiliary strainer portion 201i, so that the liquid extraction efficiency is further improved.

The hold member 204 is not limited to a solid body as long as it has a structure capable of maintaining a rigid pressing surface and a food guide passage, and is a metal plate pressed into a conical convex surface (for example, a stainless steel plate). It is also possible to adopt a configuration such as reinforcing from the back with a rib structure. In that case, you may form a raw material food supply channel | path with a pipe material.
