Description

[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology is used to solidify liquids such as oil contained in the frying process during the manufacturing process of relatively lightweight and fragile products such as snacks. It belongs to the field of processing technology for solid-liquid separation, which reliably reduces the amount of water and produces solid products with a low liquid content.

<Summary> The invention of this application applies rotational force to light products such as snack foods during the process of transporting them from the pre-process frying process to the next seasoning process, etc. This invention relates to a solid-liquid separation method for lightweight products in which a liquid content such as oil is reduced from a solid content through force and then sent to the next stage of the process, and an apparatus directly used in the method, and in particular,

This invention relates to a method and apparatus for solid-liquid separation of lightweight products, which reduce centrifugal force, take the products out of the device, and transport them to the next stage of processing.

<Prior Art> As is well known, as citizens' lives become more affluent, their consumer lifestyles also improve, and as a variety of foods and the like are handled in the distribution market, hygiene management and the like have become important.

By the way, some foods are undesirable because of their material quality over time after production.For example, fried snack products may undergo a frying process such as frying in oil during production, so the solid content may be low. On the other hand, if the oil is shipped to the secondary market in a state containing O immediately after frying, it may take a long time to reach the consumer, or the temperature may be unfavorable for display at the store. In addition to being adversely affected by light such as ultraviolet rays and producing an unpleasant taste as a product, the oil content oxidizes over time and loses its commercial value, so there is a rapid cooling process after the frying process. In addition, diversifying dietary habits will also help prevent obesity and reduce the amount of calories consumed by reducing oil content in order to meet consumer needs, so it is important to improve the packaging process. In between, a step is required to reduce the oil content from the solid content.

By the way, since these kinds of fried snack products are lightweight products with a light solid content and a large bulk, the oil content can be reduced by using a solid-liquid separator such as a press type or screw decanter type. For example, since the solid state is destroyed and cannot be used as a product, for example,
Solid-liquid separation devices using centrifugal force have been developed, such as the one devised in No. 7-41563.

<Problems to be Solved by the Invention> However, in the solid-liquid separation using centrifugal force in the prior art invention, since the solid-liquid separator or lower screen is rotated using a plurality of pairs of opposing perforated belts, A large centrifugal force is suddenly applied to the lightweight products being fed into the process in the initial process, and although the oil content is reduced, the drawback is that the lightweight solid content is destroyed.

Also, whether the horizontal centrifugal horn or O of the product being put in is 100%
Because of this, it is difficult to squeeze out the oil from the solids, resulting in a poor product yield.Also, it is necessary to separate the products so that the product value is not lost due to the mixing of destroyed products. This has the disadvantage of resulting in high costs.

<Object of the Invention> The object of the invention of this application is to solve the technical problem of solid-liquid separation using centrifugal force in removing liquid from lightweight products such as fried snacks based on the above-mentioned prior art. The challenge was to take advantage of the advantage of centrifugal force, which removes and reduces liquid content without destroying the inherently lightweight solid content. In the discharge process, the centrifugal force is reduced, and in the solid-liquid separation process, an appropriate centrifugal force is applied so that the amount of liquid required by the product is less than the destructive force of the lightweight product to ensure that excess liquid is removed. It is an object of the present invention to provide an excellent solid-liquid separation method and apparatus for lightweight products that will benefit the field of chemical engineering technology application in the food industry by reducing the amount of water used.

<Means/effects for solving the problem> In order to solve the above-mentioned problem, the structure of the invention of this application, which is based on the above-mentioned claims, is to solve the above-mentioned problem. At the inlet of a rotating body, such as one that has a rotation center on the horizontal or vertical axis, a lightweight product such as a fried snack product that contains a mesh belt or the like with a small eccentricity from the rotation center is used. The liquid content is transferred to the belt via the rotating chute relative to the cylindrical chute, and the centrifugal force is small at the beginning, but gradually increases as the amount of eccentricity from the center of rotation of the porous belt increases, and the contained liquid is removed and reduced. In the middle part, solid-liquid separation is performed by centrifugal force within a range that does not exceed the destructive force of lightweight products.The centrifugal force is again reduced by a perforated belt that reduces eccentricity with respect to the center of rotation, and in the latter discharge process. The product is discharged through a chute to the next process with almost no centrifugal force applied. (Technical measures have been taken to make the solid-liquid separation work effectively by creating a commotion and controlling the removal of liquid by adjusting the centrifugal force as necessary.) be.

<Embodiments> Next, embodiments of the invention of this application will be described below with reference to the drawings. Incidentally, in all the embodiments, the same aspects will be explained using the same reference numerals.

The illustrated embodiment is an embodiment in which the oil content is reduced in the cooling process after oil frying in the frying process and in the intermediate process of the packaging process of a fried snack (not shown) of a snack product as a lightweight product, and is shown in Figures 1 to 9. In the embodiment, as shown in FIG. 9, the solid-liquid separator 1 has a rotating body 2 on its supply side, and a belt conveyor 3 from the previous frying process.
A curved cylindrical chute 4 is connected to the cylindrical chute 4, and a rotary chute 5 is connected to the cylindrical chute 4 behind a seal.In addition, in the latter stage discharge process, a belt conveyor is connected to the next stage cooling process and packaging process. A fixed chute 7 is connected to the drum 6 under the seal, and a drum 8 with an approximately spindle-type outer diameter is provided to ensure safety. The diameter is smaller than the center of rotation, and a ring 9. Support rollers 10 and 10 provided on the base abut on 9', as shown in FIG. 3, to rotatably support the rotating body 2.

Further, in this embodiment, a pinion 13 of a motor 12 provided at the base meshes with a gear 11 formed on the front ring 9 to rotate the drum 8 at a set speed.

A pair of oil ejecting nozzles 14 and 14 are provided in the large diameter portion of the drum 8 in the approximate middle thereof, and an inner ring 15 is fixed to the drum 8 by means such as abutment. The inner ring 15 is connected to the outer ring 1 which is properly fixed to the base via a ring-shaped seal 16.
As shown in FIG. 2, a swivel joint 18 is formed with the outer ring 17 which is slidable in the circumferential direction at the outer ring 17. As shown in FIG. It is connected to a discharge passage 21 through a fixed nozzle 19 and a joint 20 on the side, and is further connected to an oil tank 22 to store oil separated from solid components and process it as appropriate.

As shown in FIGS. 2 to 7, the inner surface of the drum 8 is provided with a pair of belt devices 23 and 23 that extend along the axial direction in the diametrical direction. Roller 25 and driven roller 26 on the surface part
The feed side and the return side are always similar in shape to the inner surface of the drum 8, so that whenever the centrifugal force is applied,
A perforated plate along the inner and outer surfaces to maintain the similar shape? 7.
27, and on the return side, as shown in FIG. The feeding position is maintained by maintaining a fixed state since the feeding position is not rotated.

Note that the mechanical parts of the nozzle 14 and swivel joint 18 are omitted in FIG. 4.5 for convenience of illustration.

As shown in FIG. 6, the support shaft of the drive roller 25 is pivotally supported by a frame 29 provided in the diametrical direction at the rear, and a bevel gear 30 provided at one end is attached to the frame 29. It meshes with a bevel gear 32 provided on the output shaft of a motor 31 as a rotating device, and rotates the rotating body 2.
A cable 36 is connected to the rotary shaft 34 which passes through the center of the chute 7 on the rear side through a seal 33 and is inserted through a well-known slip ring 35 provided at the outer end of the chute 7.
is connected to a power supply device (not shown).

As shown in FIG. 1, the drum 8 of the rotary body 2 is fixedly supported by support bars 37, 37 at predetermined positions such as the front and rear thereof to maintain its rigidity.

As shown in FIG. 7, the feeding side (inside) of the driven roller 26 portion of each mesh belt 24 is formed into a flat plate shape, and the portion around the exit of the cylindrical chute 4 is formed into a flat plate shape. A rotating chute 5 having a substantially S-shaped cross section is provided, which is formed in a semicircular shape and is relatively rotatable via a seal 16', and both edges of each semicircular portion on the inlet side are overlapped portions. 38 to prevent the fried snack product 39 from overflowing to the side after frying.

However, as shown in FIG. 7, each rotating chute 5.5 is fixed to the outlet side of the drum 8 via a bracket 40, so that it rotates together with the drum 8 and is subject to centrifugal force. Therefore, as it approaches the mesh belt 24, its eccentricity from the center of rotation increases, thereby increasing the centrifugal force. Overflow is avoided, and since the centrifugal force is close to O on the exit side of the cylindrical chute 4, an overlap portion 38 is formed to prevent lateral overflow.

Therefore, due to the shape of the chute 5 shown in FIG. 7, the fried snack product 39 after frying is not fed in a batch manner but continuously into the rotating body 2, and there is no overflow or 2, the rotating body 2 from the center of rotation of each mesh belt 24 is small at the entrance and exit, that is, the front and rear parts, and is largest at the swivel joint 18 in the middle part. The centrifugal force is the largest in the middle part, and the centrifugal force is smaller in the front and rear parts on the entrance and exit sides, so that even in the drum 8, the fried snack product 39 is pressed against the mesh belt 24 side. The oil content 41 is removed from the swivel joint 18 as shown in Fig. 1 by the solid-liquid separation effect caused by the centrifugal force that gradually increases without overflowing inside, and the solid content 39' is separated by the centrifugal force that gradually decreases. The sheet is transported backwards while being in contact with the mesh belt 24, and transferred and conveyed from the chute 7 to the belt conveyor 6 at the next stage.

Note that the solid-liquid separation effect is performed by the centrifugal force that increases and decreases in each mesh belt 24 between the rotating chute 5 at the front and the chute 7 at the rear. The rotational speed of the motor 12, the pinion 13 as a rotating device, and the gear 11 is designed in advance to be a rotational speed that does not destroy the solid content. The speed can be changed as appropriate.

In addition, since skirt portions 28 are formed on both edges of the feeding side of the mesh belt 24 in the drum 8, fried snack products 39 and solid matter 39 being conveyed can be more actively removed.
The A-bar flow into the drum 8 is more actively prevented in conjunction with the adhesion to the mesh belt 24 due to centrifugal force.

In the illustrated embodiment, the relative proximity of the outlet and inlet sides of the mesh belts 24, 24 to each other is designed to be small, so that sudden centrifugal force is not applied to the fried snack product 39 transferred from the cylindrical chute 4 to the mesh belt 24. In addition, on the exit side, mesh belt 2
From 4.24, the amount of Δ2 is set so that the centrifugal force on the fixed chute 7 will suddenly change and the liquid will not be discharged.

Further, in this embodiment, for convenience of illustration, the gap between the outlet side and the inlet side of the mesh belts 24, 24 is shown wide and deformed.

In the solid-liquid separator 1 configured as described above, when the fried snack 39, which is a lightweight product, is conveyed by the belt conveyor 3 from the frying process and supplied from the cylindrical chute 4 to the rotating body 2, the motor 12, pinion 13, and gear 11 are The cylindrical chute 4 is continuously fed into the drum 8 which is rotated through the cylindrical chute 4.
On the outlet side of the fried snack product 39, centrifugal force is gradually increased through eccentricity gradually increasing from the center of rotation by a pair of rotary chutes 5 connected via seals 37 and semicircular overlap portions 38. is attached to the rotary chute 5 by the centrifugal force, and is transferred and fed to the starting end of each mesh belt 24 by receiving a component of the feeding force in an inclined position.

Each mesh belt 24 is supported by an exit side frame 29, and a drive roller 26 is operated via a bevel gear 32, 30 by a motor 31 which is rotated by electric power supplied from a slip ring 35 at the end of a rotating shaft 34. Since the fried snack products 39 are rotated independently of the rotating body 2 by the driven rollers 26 and 26, the fried snack products 39 are sent to the rear while being attached to the mesh belts 24 under the centrifugal force of the mesh belts 24. Tunnel-shaped perforated plate 21.21 and skirt portion 28.2
8, the fried snack products 39 are prevented from overflowing into the drum 8 and are sent backwards, and as the eccentricity of each mesh belt 24 from the center of rotation increases, the centrifugal force is increased and the product gradually Under the squeezing action, the oil content flows through the mesh of the mesh belt and the perforated plate 2.
7. From the nozzle 14.14 in the large diameter part of the middle part through the fine hole group of 21 to the swivel joint 18.18
The baton is passed from the inner ring 15 to the outer ring 17 via.

During this period, the joint 2 is removed from the nozzle 19 of the outer ring 17 without overflowing due to the seal ring 16.
0 to the oil tank 22 from the discharge passage 21, and the solid content 39', which has been reduced by removing the oil content 41, is centrifuged from the middle part of the maximum diameter with its eccentricity with respect to the center of rotation reduced. Metschbelt whose power is reduced 24.2
4, the centrifugal force is further reduced at the exit portion of the chute 7, and the belt conveyor 6 conveys it to the next stage without receiving almost any centrifugal force from the chute 7.

During this time, as mentioned earlier, the motor 1 is connected to the rotating body 2.
The rotational force from 2 is given a rotational speed such that it becomes a centrifugal force that does not cause the destruction of the solid content, and therefore,
Solid content 39 discharged from the chute 7 and sent to the next stage
' is not damaged in any way and the product yield is not reduced.
It will be delivered as a fried snack product as designed.

In this way, by continuous processing of fried snack products 39 from the previous stage process to the next stage, the content can be stably reduced by continuously removing the oil content 41 of 1 solid content, and the product accuracy can be improved. It can be obtained with good yield.

Further, in the embodiment shown in FIG. 10, the rotation is applied from the side of the rotating body 2 of the above-mentioned embodiment, but the rotation is applied by a chino from an externally provided motor 12' or by a center drive via a belt. This is an embodiment in which the rotating body 2 is rotated.

Furthermore, the embodiment shown in FIGS. 11 and 12 is a more specific embodiment in which both the drive for the rotating body and the rotation of the belt device 23 are performed from an external drive system, and the embodiment shown in FIG. A pair of rotating bodies 2 separated from each other by a predetermined distance

The power bow engages with the outer cap 111 of another ring 91 installed parallel to and close to one ring 9'' to apply rotational force to the motor 31' via a chain mechanism. Furthermore, the support bar 37 is connected to the pinion 30' that meshes with the internal gear 111 of the other ring 9#'.
The drive row 525 is rotated by a rotating shaft 34'' supported by a bearing provided on the shaft 32. The rotation of the mesh belt 24 and the rotation of the mesh belt 24 are inputted from separate drive systems, and therefore, in this embodiment, the drive system numbers of the two motors 12' and 31' are inputted separately. It can be given from the system, and by doing this, ring 9'' and
A difference in rotation between 9'' and 9' was intentionally created, and the mesh belt 24.24 was installed on a rotating shaft 34ff that was supported on a bearing provided on a support bar 37 inside the rotating body 2 that housed the mesh belt 24. By applying rotation to the pinions 30', 30', the conveying side of the mesh belt 24.24 can be run from the inlet direction to the outlet direction via the bevel gears 32.32 and further 30.30.

The rotational speed of the motor 12' is controlled so that the rotating rings 9'', 9' can be conveyed at an optimum speed for the fried snack product 39, and the running speed of the mesh belt 24, 24 is controlled by the rotational speed of the motor 31'. 91.9″′
If 91 and 91 are at the same speed, pinions 30' and 30 will not occur.
By intentionally creating a rotation difference between the rotation rings 91 and 9'' and 9', the mesh belts 24 and 24 inside the rotating body 2 can change the rotation difference arbitrarily.
It is also possible to change the time period during which the centrifugal force is applied to the fried snack product 39 fed upward.

In this embodiment, it is also possible to transport the fried snack product 39 from the exit side to the entrance side if desired.

It goes without saying that the embodiments of the invention of this application are not limited to the above-mentioned two-way sides. For example, the axial shape of the mesh belt is the same as that of the front section, intermediate section, and rear section of the above-mentioned embodiments.
In addition to bending the parts, it is also possible to create a gentle curve that gradually increases or decreases so that the amount of eccentricity from the center of rotation changes steplessly. It is possible to adjust the amount of eccentricity from the center of rotation at the exit side or the intermediate part using an appropriate adjustment device, and furthermore, it is also possible to change the supply of lightweight products from a flow state to a batch state. It is possible, and furthermore,
Various aspects can be adopted, such as the possibility of imparting imaging to the mesh belt.

It is also possible to adopt a mode in which a micro-vibration device is attached to the rotating body to effectively perform solid-liquid separation, a sterilizing lamp is installed inside the rotating body, or a heating device is installed on the side.

Moreover, it goes without saying that the applicable lightweight products are not limited to fried snack products, but can also be applied to other moisture-containing products.

Regarding the product feeding mode, it is possible to use not only the horizontal feeding type of the above-mentioned embodiment, but also a vertical top-to-bottom conveyance mode, a diagonal conveyance mode, and even a combination of these modes. It is.

And, as far as safety is possible in terms of design changes,
Omit the drum and attach the belt device directly to the ring,
When the mesh belt is of the guide rod type, maintenance can be facilitated by omitting the perforated plate skirt portion, or by using not only one pair of perforated belts but two or more pairs.

Furthermore, in addition to the rotary body having a circular cross section as in the above-mentioned embodiment, which is a design change, it is also possible to use a rotary body having a rectangular cross section, thereby simplifying the structure and increasing the strength and rigidity.

As an example of application, it is possible to use centrifugal force to spray the seasoning inside the drum or onto the mesh belt, and the mesh belt can be made of not only wire mesh but also nylon or the like.

<Effects of the Invention> As described above, according to the invention of this application, it is basically possible to process lightweight products such as fried snacks that contain liquid components such as oil from the previous step of the process to the next step. When removing and reducing liquid content from solid matter, it is possible to generate centrifugal force by the rotation of the circulating porous belt in solid-liquid separation via centrifugal force caused by the rotation of the conveying porous belt, and furthermore, By reducing the eccentricity from the center of rotation on the inlet and outlet sides and increasing it in the middle, centrifugal force can be reduced in the supply from the previous stage of the inlet and outlet sides and the discharge process to the next stage. It softens the impact force on lightweight products when connected, ensures solid-liquid separation due to increased centrifugal force in the middle part, prevents destruction of solids, improves product yield, and reduces liquid removal as per M1. The excellent effect of being able to obtain lightweight products is demonstrated.

Moreover, by gradually increasing and decreasing the eccentricity φ from the center of rotation from the inlet side to the intermediate part and from the intermediate part 81S to the outlet side, it is possible to avoid sudden changes in centrifugal force and gradually squeeze out the liquid from the solid. As a result, the excellent effect of efficiently squeezing out the liquid content in the light beef product without causing sudden changes in squeezing the liquid content is achieved.

In addition, since solid-liquid separation processing can be performed continuously in a flow system rather than in the conventional batch method, it is possible to perform continuous day and night processing unmanned in plants and factories. Since it is possible to do this, it has the profound effect of increasing efficiency and improving workability through labor saving.

In the past, it has also been shown to have the advantage of lowering product costs.

In addition, because there are few moving parts and the internal structure is simple, internal inspection is easy, maintenance and inspection are easy, and there are fewer breakdowns.
It is easy to perform initial manufacturing and assembly, and has the excellent effect of lowering not only initial costs but also running costs.

Furthermore, adding micro-vibrations to the rotating body or perforated belt has the effect of making solid-liquid separation more efficient, and in addition, providing a sterilization device has the effect of sterilizing the solid-liquid separation process. Furthermore, a heating device can be added to accelerate the drying of the product.

Furthermore, in order to more reliably collect and remove liquid components such as oil, and to prevent solid contents from being destroyed, the removed liquid does not contain any solids, and as long as that is the case, the removed liquid can be recovered. It can be treated appropriately and reused, which brings about excellent economic benefits.
