Description

The present invention relates to a food residue processing device and a system, and more particularly to a food residue processing device and a system for treating a food residue such as vegetables, beans, fruits, and fish and shellfish.

Conventionally, as a device for finely crushing food residue for home use, there is a swill crusher also called a disposer as shown in Patent Document 1. The disposer is attached to the drain of the cooking sink, crushes the food residue while running tap water, and drains it into public sewage together with tap water. Using a disposer is expected to reduce garbage collection and disposal costs, so some local governments recommend using it.

In recent years, dietary simplification has been progressing due to the nuclear family or the advancement of women into society. Lunch boxes, side dishes, and cut vegetables are sold at convenience stores and supermarkets. As for cut vegetables, several food processing manufacturers have already entered the market.
Japanese Unexamined Patent Publication No. 2001-269579

However, the invention disclosed in Patent Document 1 is intended for processing food residue generated at home, and it is difficult to apply it for business use for the following reasons.

First, the amount of food residue that an existing household disposer can process at one time is typically just enough to hold with both hands. The amount of food residue generated in commercial food processing factories and the like far exceeds this, and it is difficult to process a sufficient amount.

In addition, even if the existing household disposer is simply enlarged, the disposer of the type attached to the drain of the cooking sink basically crushes the food residue only with the rotary blade whose axis is vertical. In this case, it is difficult for the rotary blade and the food residue to come into contact with each other, and the amount of the food residue processed per unit time is limited.

Therefore, it is an object of the present invention to provide a food residue processing apparatus suitable for commercial use and a system provided with the apparatus.

In order to solve the above problems, the food residue processing apparatus and system of the present invention are used.
A cutting processing unit that cuts the processing target (for example, the cutting processing unit 5 in FIG. 2) and
A crushing processing unit (for example, the crushing processing unit 6 in FIG. 2) that crushes the processing target cut by the cutting processing unit, and a crushing processing unit.
A supply unit that supplies water to the treatment target (for example, a water spray unit 4 in FIG. 2) and
To prepare for.

The cutting processing unit is

A first and second cutting mechanism comprising a rotation axis (eg, rotation axis 8 in FIG. 3) arranged in layers through
The rotary cutting portion of the second cutting mechanism is meshed and arranged between the rotary cutting portions of the first cutting mechanism.
A crushing motor (for example, the cutting motor 7 in FIG. 4) that rotates the rotation shaft of the first cutting mechanism and the rotation shaft of the second cutting mechanism in opposite directions may be provided.

The crushing processing unit is

An annular member (for example, the annular plate 25 in FIG. 2) which is arranged to face the locus region of the crushed tooth and has a passage port (for example, the slit 25a in FIG. 5) through which the processing target after the pulverization treatment passes.
May be provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Explanation of outline)
First, the outline of the food residue processing apparatus 1 of the present embodiment will be described. In the present embodiment, waste vegetables generated after the production of cut vegetables will be described as an example of processing, but food residue such as vegetables, beans, fruits, and fish and shellfish may be treated.

It is thought that waste vegetables generated in food processing factories, etc. often use a wider variety of foodstuffs than those generated at home, and their sizes, hardness, shapes, etc. vary. Is normal.

However, even in the case of waste vegetables of the same type, the size, hardness, shape, etc. may vary. That is, taking cabbage as an example, it includes whole cabbage that is damaged and must be disposed of, curled leaves on the outer shell, and cores in the center, which have different parts. Therefore, it is not efficient to uniformly treat such waste vegetables in the same manner.

Therefore, in the present embodiment, first, there is a step of cutting the waste vegetables in order to reduce the size to a predetermined size or less, and a step of crushing the cut waste vegetables. Further, in the present embodiment, tap water or the like is sprayed on the waste vegetables to be treated in addition to the treatment of these steps.

Therefore, the waste vegetables after the crushing treatment are in the form of a slurry because they contain tap water and the like. Therefore, as in the case of a household disposer, the waste vegetables after the crushing treatment can be drained into public sewage as wastewater.

In this embodiment, in order to continuously and smoothly perform the cutting treatment step and the crushing treatment step, the cutting treatment section is provided above and the crushing treatment section is provided below the cutting section. That is, in the present embodiment, the waste vegetables cut by the cutting processing section are dropped to the crushing processing section by their own weight and crushed.

However, a belt conveyor is prepared in which the cutting processing unit and the crushing processing unit are arranged horizontally, and the cutting processing unit is upstream and the crushing processing unit is downstream, and the waste vegetables are moved horizontally. It is also possible to execute the cutting process and the crushing process while doing so.

(Explanation of configuration)
FIG. 1 is a schematic external view of the food residue treatment system of the present embodiment. In FIG. 1, a food residue processing device 1 for processing food residue in a slurry form, a storage tank 31 for storing a certain amount of waste vegetables processed in a slurry form by the food residue processing device 1, and a food residue processing device 1 are used. The discharge pump 32 used when sending the waste vegetable treated in the form of a slurry to a wastewater treatment facility is shown.

The food residue processing apparatus 1 has an approximate size of, for example, 180 cm to 250 cm in height and 80 cm to 120 cm in width, and has a square shape, but may be larger or smaller than this. For example, it may have a cylindrical shape. The specific configuration of the food residue processing apparatus 1 will be described later with reference to FIGS. 2 to 5.

The capacities of the storage tank 31 and the discharge pump 32 can be selected according to the amount of waste vegetables processed by the food residue processing apparatus 1. By doing so, the pump capacity can be reduced, and a fixed amount of discharge can be made toward the wastewater treatment facility.

FIG. 2 is a schematic configuration diagram of the food residue processing apparatus 1 shown in FIG. In FIG. 1, as a main part of the food residue processing apparatus 1, an inclined conveyor 2 for conveying waste vegetables, a receiving hopper 3 for receiving waste vegetables conveyed by the inclined conveyor 2, and tap water being supplied into the receiving hopper 3. A water spraying unit 4 for cutting, a cutting processing unit 5 provided under the receiving hopper 3 for cutting waste vegetables received by the receiving hopper 3, and a cutting processing unit 5 provided under the cutting processing unit 5 for cutting. The crushing processing unit 6 for crushing the waste vegetables cut and processed by the processing unit 5 is shown.

The water spray unit 4 includes an electromagnetic valve 4a that controls the presence / absence and supply amount of tap water or the like to the receiving hopper 3, and a nozzle 4b that atomizes the tap water that has passed through the electromagnetic valve 4a.

The nozzle 4b may be, for example, a nozzle hole having a diameter of 3 mm or more so as not to be clogged by contact with waste vegetables. Further, the amount of tap water discharged from the nozzle 4b may be, for example, 3 L / min to 6 L / min in consideration of the fluidity of the waste vegetables in the form of slurry.

Here, an example of supplying tap water or the like from the water spraying unit 4 to the receiving hopper 3 is described, but the cutting processing unit 5 or the crushing processing unit 6 may be supplied. However, it is preferable because it has the following advantages of supplying to the receiving hopper 3.

That is, the fluidity of the discarded vegetables in the cutting processing unit 5 and the crushing processing unit 6 is increased, and the rotary crushing unit 24 (FIGS. 3 and 4) described later can be rotated at high speed, so that the waste vegetables can be discarded during the crushing process. There are advantages that the dispersion effect of vegetables is improved, the solid-liquid interface energy is lowered, and the slurrying efficiency of waste vegetables is increased.

Further, the cutting processing unit 5 and the crushing processing unit 6 are connected by a connecting hopper 20 that tapers from the upstream to the downstream. However, the shape of the connecting hopper 20 is an example and is not limited to this, and may be, for example, a cylindrical shape having the same diameter, or a shape that becomes thicker from the upstream to the downstream.

The crushing processing unit 6 is mounted on a gantry 30 in which a crushing motor 29 is located in a central space composed of a plurality of legs. A discharge pipe 26b for flowing the crushed waste vegetables toward the storage tank 31 is connected to the downstream of the crushing treatment unit 6.

The operation of each part can be started / stopped at regular time intervals. For example, the amount of waste vegetables input to the receiving hopper 3 is measured and started based on the measurement result. It is also possible to adopt a sensing control that stops when the expected processing time corresponding to the input amount is reached.

Further, by providing a timer that times out in advance at the operation end time of the food residue processing device 1 itself and a control unit that turns off the main power of the food residue processing device 1 after the time-out, the power saving effect can be enhanced or unmanned automatic operation can be performed. Can be realized.

FIG. 3 is a front view showing the internal configuration of the food residue processing apparatus 1 shown in FIG. FIG. 3 is also a cross-sectional view taken along the line BB in FIG. FIG. 3 also shows the waste vegetables 40 before the cutting treatment by the cutting processing unit 5, the waste vegetables 40a cut by the cutting processing unit 5, and the waste vegetables 40b crushed by the crushing processing unit 6. ..

The cutting processing unit 5 cuts the waste vegetables 40 falling from the receiving hopper 3 into the internal space surrounded on all four sides by the side plate 17 and the bearing plate 13 (FIG. 4) described later. A biaxial cutting mechanism, which is a mechanism, is adopted.

When a set of biaxial cutting mechanisms is used as shown in FIG. 3, most of the waste vegetables 40 are cut in only one direction. If two sets of biaxial cutting mechanisms are prepared and each biaxial cutting mechanism is arranged upstream and downstream in a manner in which the axes are orthogonal to each other, most of the waste vegetables 40 are cut into both. Is also one method.

In both the first and second cutting mechanisms, a disk-shaped rotary cutting portion 14 in which a plurality of cutting teeth 14a are located on the outer peripheral portion and a plurality of rotary cutting portions 14 are layered in the depth direction of the drawing through their axes. A rotary shaft 8 arranged in the above, a key 8a for connecting the rotary shaft 8 and the incision tooth 14a, and a spacer 15 having a diameter smaller than that of the incision tooth 14a provided between the adjacent incision teeth 14a are provided. Is meshed and arranged in such a manner that the rotary cutting portion 14 of the second cutting mechanism is located between the rotary cutting portions 14 of the first cutting mechanism.

The thickness of the notch teeth 14a and the thickness of the spacer 15 may be, for example, about 0.2 cm to 2.0 cm in order to finally make the waste vegetables 40b into a slurry. However, it is not necessary that the thicknesses of the first cutting mechanism and the second cutting mechanism are all the same as long as the symmetry is ensured so that the first cutting mechanism and the second cutting mechanism are meshed with each other. The rotation speed of the incision tooth 14a is not limited to this, but may be, for example, 20 rpm to 60 rpm.

It should be noted that a scraping bar or the like having a thickness of, for example, about 80% of the thickness of each spacer 15 may be inserted between the incision teeth 14a at positions facing each spacer 15 and adjacent to each other. By doing so, even if the waste vegetable 40b is caught between the cut teeth 14a, it can be scraped off.

FIG. 4 is a cross-sectional view taken along the line AA in FIG. 2 for explaining the cutting processing unit 5 of FIG. As shown in FIG. 4, in the present embodiment, the first cutting mechanism and the second cutting mechanism are meshed and arranged so that the positions of the respective cutting teeth 14a are staggered.

In other words, the spacer 15 of the second cutting mechanism is located on the extension of the rotary cutting portion 14 of the first cutting mechanism in the surface direction, and on the extension of the rotary cutting portion 14 of the second cutting mechanism in the surface direction. Is located with the spacer 15 of the first cutting mechanism.

Further, FIG. 4 shows a cutting motor 7 for driving the first and second cutting mechanisms in addition to the cutting processing unit 5. In addition to the portion described with reference to FIG. 3, the cutting processing unit 5 includes a pair of an output shaft 7a extending from the cutting motor 7, a coupling 9 for connecting the output shaft 7a and the rotating shaft 8 on the left side of the drawing, and a pair. A pair of gears 10 and 10a meshed with the rotating shaft 8 and a screw 10b connecting the gear 10a and the rotating shaft 8 on the right side of the drawing are shown.

In addition, FIG. 4 shows a pair of ball bearings 11 provided at both ends of the rotary shaft 8 on the left side of the drawing, a pair of bearing housings 12 into which the pair of ball bearings 11 are fitted, and a pair of bearings. A pair of bearing plates 13 to which the housing 12 is fixed, a collar 16 that defines the positions of the rotary cutting portion 14 and the spacer 15 provided adjacent to the pair of ball bearings 11, and the opposite side to the cutting motor 7. The end plate 16a provided adjacent to the collar 16 located in the above is shown.

Although not shown in FIG. 4, a ball bearing or the like (not shown) is also provided on the rotating shaft 8 side on the right side of the drawing. This means that the configurations of the first cutting mechanism and the second cutting mechanism are similar.

Return to FIG. In the present embodiment, the connecting hopper 20 has a tapered shape from upstream to downstream as described above in appearance when viewed from the side surface, but has the same diameter shape accommodated in the crushing processing unit 6. It has a cylindrical portion 21 and a flange portion 22 extending radially from the upper end edge portion of the cylindrical portion 21.

The cylindrical portion 21 defines the side outer edge of the processing space when the waste vegetables 40a dropped from the cutting processing portion 5 are pre-crushed by the rotary striking member 23 described later, and the lower end of the cylindrical portion 21 is a rotary striking member. It extends downward from the upper surface of the 23, and its inner surface faces the outer locus surface 23a of the rotary impact member 23.

The flange portion 22 is formed with a through hole for a bolt that connects the connecting hopper 20 and the crushing processing portion 6. It is not essential to connect the connecting hopper 20 and the crushing processing section 6 through the flange section 22, but with such a configuration, it is easy to replace the consumable rotary impact member 23 and the rotary crushing section 24. Become.

In the crushing processing unit 6, the crushing processing space is defined by the upper housing 6a connected to the connecting hopper 20 and the lower housing 6b connected to the upper housing 6a.

In the crushing processing space, there is an axial center between the rectangular rotary striking member 23 that performs pre-crushing pretreatment using the rotational force on the waste vegetables 40a falling from the cutting processing unit 5, and the rotary striking member 23. A slit 25a (FIG. 5) through which a plate-shaped rotary crushing section 24 connected to each other in a aligned state, a boss 27 attached to the rotary crushing section 24, and waste vegetables 40b crushed by the rotary crushing section 24 pass through. ) Is provided.

FIG. 5 is a cross-sectional view taken along the line CC in FIG. 3 for explaining the crushing processing unit 6 of FIG. In the center of FIG. 5, the rotary striking member 23 and the rotary crushing portion 24 in which the axis is located are shown. The rotary crushing portion 24 has a base portion 24b and crushing teeth 24a located on the outer peripheral portion of the base portion 24b.

The thickness of the gap between the rotary crushing portion 24 and the annular plate 25 can be, for example, about 0.5 mm to 2.0 mm. The rotation speed of the rotary pulverization unit 24 can be, for example, 1500 ppm to 2000 ppm.

The annular plate 25 is arranged to face the locus region of the crushed tooth 24a. As described above, the annular plate 25 is radially formed with a plurality of slits 25a through which the waste vegetables 40b pass. Each slit 25a has, for example, a round shape having a length of 30 mm to 60 mm and a width of 2 mm to 4 mm, and 50 to 150 slits can be provided. Further, the outer edge of the annulus plate 25 is sandwiched between the upper housing 6a and the lower housing 6b, and the inner edge thereof is inside the outer edge of the base portion 24b.

Return to FIG. An opening 26c is formed in the central portion of the bottom plate 26a of the lower housing 6b. A crushing motor 29 is located below the opening 26c. An output shaft 29a extending from the crushing motor 29 is passed through the opening 26c. The crushing motor 29 is flange-joined to the bottom plate 26a and is connected to the lower surface of the bottom plate 26a with bolts.

A waterproof cap 28 that covers the opening 26c is attached to the upper surface of the bottom plate 26a. An opening through which the output shaft 29a passes is also formed in the central portion of the waterproof cap 28, and the opening and the boss 27 are sealed with a waterproof seal 28a.

Further, an opening 26d communicating with the above-mentioned discharge pipe 26b is formed in the peripheral portion of the bottom plate 26a. The bottom plate 26a may be shaped like a mortar toward the opening 26d to improve the discharge efficiency.

(Explanation of operation)
First, an outline of the operation of the food residue treatment system will be described with reference to FIG. 1. When the waste vegetables 40 (FIG. 3) are put into the food residue processing device 1, the driving of the food residue processing device 1 is started accordingly, and the driving of the discharge pump 32 is also started accordingly.

The waste vegetable 40 becomes the waste vegetable 40a (FIG. 3) by the cutting process. Further, the waste vegetable 40a becomes a slurry-like waste vegetable 40b (FIG. 3) by the pulverization treatment. When the storage tank 31 is filled with the waste vegetables 40b, the food residue processing device 1 is stopped.

The outline of the operation of the food residue processing apparatus 1 will be described with reference mainly to FIG. The waste vegetables 40 (FIG. 3) generated during vegetable cutting are conveyed to the food residue processing device 1 by the inclined conveyor 2.

The waste vegetables 40 that have reached the food residue processing device 1 are charged from the receiving hopper 3 located above the gantry 30. When the solenoid valve 4a is energized with this as a trigger, tap water is sprayed from the nozzle 4b into the receiving hopper 3. Therefore, the waste vegetables 40 thrown into the receiving hopper 3 fall into the cutting processing section 5 with tap water attached.

The cutting processing unit 5 cuts waste vegetables 40 of various sizes, hardnesses, and shapes into waste vegetables 40a that can be accommodated within a certain size. The waste vegetables 40a fall into the crushing processing unit 6 via the connecting hopper 20.

In the crushing processing unit 6, the cut waste vegetables 40a are crushed into a slurry-like waste vegetables 40b. The waste vegetables 40b (FIG. 3) are stored in the storage tank 31 through the discharge pipe 26b.

The cutting process and the crushing process will be described with reference to FIG. 3 mainly. Further, a supplementary explanation thereof will be given with reference to FIGS. 4 and 5.

In the cutting processing unit 5, since the cutting motor 7 is energized, the power thereof is transmitted to the pair of rotating shafts 8 via the output shaft 7a, the coupling 9 and the gears 10 and 10a. As a result, the rotary cutting portion 14 on the left side of the drawing is rotated clockwise, and the rotary cutting portion 14 on the right side of the drawing is rotated counterclockwise.

The waste vegetables 40 that have fallen into the cutting processing section 5 in this state are cut by the plurality of cutting teeth 14a provided in each rotary cutting section 14. Specifically, each cut tooth 14a is cut while scraping the waste vegetables 40 from both sides so as to be pierced from both sides. Then, the waste vegetables 40a that can be accommodated within a certain size pass between the spacer 15 and the notch teeth 14a, and fall to the crushing processing unit 6 via the connecting hopper 20.

In the crushing processing unit 6, the crushing motor 29 is energized, and the power thereof is transmitted to the rotary crushing unit 24 and the rotary striking member 23 via the output shaft 29a. As a result, these are rotated at high speed.

Most of the waste vegetables 40a that have fallen into the crushing processing unit 6 in this state are pre-crushed by the rotary striking member 23, and then proceed in the circumferential direction by the centrifugal force of the rotary striking member 23 or the like.

As a result, the waste vegetable 40a passes between the cylindrical portion 21 and the rotary crushing portion 24 and collides with the inner wall of the upper housing 6a. Since the inner wall of the upper housing 6a has a cross section inclined in a V shape, the waste vegetables 40a face the lower side of the drawing and reach the annulus plate 25.

Since the crushed teeth 24a of the rotary crushing portion 24 subsequently pass at high speed, the waste vegetables 40a are crushed by the shearing force between the crushed teeth 24a and the slit 25a. In addition, it is also crushed by the frictional force between the lower surface of the crushed tooth 24a and the upper surface of the annular plate 25.

As a result, the waste vegetable 40a becomes a waste vegetable 40b having a size capable of passing through the slit 25a formed in the annular plate 25. Moreover, since tap water is continuously supplied from the water spray unit 4 even in the crushing treatment step, the waste vegetables 40b are in the form of a slurry.

Therefore, the discarded vegetables 40b pass through the slit 25a and fall from the upper housing 6a side to the lower housing 6b side. Since the lower housing 6b is provided with the opening 26d, the waste vegetables 40b will go to the discharge pipe 26b through the opening 26d.

Actually, when 15 or more kinds of waste vegetables 40 such as cabbage, carrot, lettuce, pumpkin, and honey, which have a total weight of about 3000 kg, were processed using the food residue processing device 1, a slurry-like waste vegetable 40b was obtained. It was confirmed that the waste was discharged through the discharge pipe 26b.

Further, when the waste vegetables 40b treated by the food residue treatment device 1 are treated by the same drainage facility as the drainage facility of Patent Document 1, they satisfy the wastewater treatment standard value set by the government and can be discharged directly into the river. confirmed.
