Description

[Detailed description of the invention] <Technology classification/field> The disclosed technology is used for the next step of sorting frozen foods such as aquatic animal meat such as block meat, fritters, and fries into standard sizes and packaging them into bags. It belongs to the technical field of the structure of sorting equipment that facilitates processing.

<Explanation of the gist> This invention is based on a rotary drum that is linked to a drive device such as a motor via rollers, etc., with a large number of screening holes drilled on its circumferential surface, and a screening hole on the base side. In addition to having an inlet for food, it also has an outlet on the front side to send out non-standard size food that has not been sorted, and a chute that connects the sorted standard size food to the next stage of processing such as filling into package cages. This invention relates to a food sorting device in which the rotary drum has a tip end inclined downwardly at a predetermined angle, and in particular, the sorting holes on the circumferential surface of the rotary drum have a sorting size range set on the base side. formed into small diameter groups of smaller pores, and
The tip side is formed into a group of relatively large diameters of food sorting size, and the sorting holes of the small diameter group are used for sorting items smaller than the set standard size of food, and
The large-diameter group of sorting holes is used for sorting out the standard-sized foods, and food items other than the standard size, which are formed by connecting several pieces of food into a lump, are sorted and discharged from the outlet. A spiral baffle plate is provided on the inside of the rotating drum to prevent the sorted food from passing forward in the rotating drum, and a large-diameter sorting hole is provided on the outside of the rotating drum. A guide plate is provided concentrically with a predetermined length in the axial direction through an interval set to be equal to or smaller than the hole diameter of the guide plate, and the side end is connected to the chute to the next stage. This invention relates to a food sorting device that is formed to extend outward from the outside.

<Prior Art> As is well known, many types of frozen foods have become available in supermarkets, etc. For example, frozen foods such as squid fritters and vegetables are usually packaged in bags or package trays. However, in the bagging process, it becomes necessary to sort the frozen foods according to standard sizes.

In this case, various types of food sorting equipment have been developed, improved, and used in the past, and so-called rotary screen type sorting equipment is known for extremely small-sized foods. However, for medium-sized seafood, fruits and vegetables, etc., a sorting device is known in which a rotary drum with sorting holes is formed or a plurality of bars are spaced apart from each other by the sorting slit interval.

For example, the invention published in Utility Model Application Publication No. 48-69793 and
In the technology disclosed in Japanese Utility Model Application Publication No. 58-86288 and furthermore, in Japanese Utility Model Application Publication No. 58-190476, a large number of screening holes are formed on the side surface of the rotating drum in groups of small diameters on the base side and in small diameter groups on the tip side. A large number of holes are formed in a group of large diameters to perform a kind of sorting of foods by size.

However, as shown in Fig. 1, the sorting equipment actually used is
The food material is transferred to a chute 5 which is connected to a conveyor 4 to the next stage bagging machine etc. by a bar-shaped sorter 3.

However, this seed sorting device had the following problems.

<Problem to be solved by the invention> In other words, in the case of frozen foods, for example, in the squid fritters and the like, processed foods are cut into predetermined shapes such as dice, coated with flour, etc. using a dusting machine, and then pre-fried. After the deep-frying process, the tofu is subjected to a freezing process and then to a sorting process, but in this case, during the deep-frying process, the tofu may become a plurality of connected lumps that are attached to each other and are connected together.
During the freezing process, they become stuck and produce large irregularly sized items, which are collected together with other non-standard foods and are disposed of, resulting in the hassle of further sorting later as defective items. The drawback was that it took a lot of time.

Conventionally, when such multiple linked foods are separated individually, they are essentially standard products, so in the subsequent sorting, it may be possible to divide them and return them to the standard product series. Even if it is a standard product, there is a risk that the bread crumbs may not be attached, the coating may peel off, or the color may be significantly defective after frying, which is not desirable in terms of product accuracy. .

<Purpose of the invention> The purpose of this invention is to solve the problems of food sorting based on the above-mentioned conventional technology as a technical problem to be solved.
Individually, according to predetermined standards, as well as non-standard so-called,
Connected foods, i.e., although the individual foods are originally standardized products, they are connected and cannot be separated into individual standardized foods due to quality reasons. It is an object of the present invention to provide an excellent food sorting device that is capable of sorting food without sending it to the next stage, thereby benefiting the field of sorting technology utilization in the food manufacturing industry.

<Means/effects for solving the problem> In order to solve the above-mentioned technical problem, the configuration of this invention is such that the sorted food that has been frozen after completing the processing in the previous step is tilted forward and downward at a predetermined angle of the sorting device. A spiral baffle plate formed on the base side of the inclined rotary drum and fed into the input port is formed inside the rotary drum and divided into a plurality of parts in the circumferential direction. The food is fed at a slow speed without passing through the rotary drum, and while passing through a group of small diameters that are smaller than the food sorting size range of a predetermined sorting hole drilled on the base side of the circumferential surface of the rotating drum. Foods smaller than the standard size of a predetermined food are sorted and dropped, and are discharged through a chute below, while the sorted food that has passed through the small diameter group is sorted through a predetermined hole drilled at the tip of the rotating drum. In the group of large-diameter holes for sorting food, those in the standard size range are provided with guide plates that are set concentrically at predetermined intervals on the outside of the rotating drum from the group of large-diameter holes. As the rotating drum rotates, it is lifted upward and discharged to a chute for the next bagging process, etc., provided at the side end of the guide plate, and standard-sized items are attached. For example, even if the tip of a large multi-connected food product is faced to the guide plate through a group of large-diameter holes, the center of gravity is on the inside as the rotating drum rotates, so it will not turn over. The food then goes back inside, repeats this operation, and is discharged as substandard food through the discharge port formed at the front end of the rotating drum.

<Example> Next, an example of this invention will be described below based on the drawings from FIG. 2 onwards. Note that the same parts as in FIG. 1 will be explained using the same reference numerals.

Reference numeral 6 denotes a food sorting device which constitutes the gist of this invention, and its frame 7 is freely conveyed to a predetermined location with respect to a base 8 via flexible rollers 9, 9, . . . A supply chute 2 is provided so as to be inclined at a predetermined angle on a downward slope, and a rotating drum 10 inclined at a predetermined angle on a forward downward slope is rotatably set from the middle to the front part of the chute 2. An input port 11 connected to a supply chute 2 is provided on the upper base side of the pivoted support, and an outlet port 12 is provided on the lower tip side.

Further, a drive roller (not shown) is attached to the circumferential surface of the input port 11 of the rotating drum 10, and a motor 13 as a drive device is provided on the upper part of the frame 7.
It is made rotatable by a drive roller rotated by power from a speed reducer 14 and a transmission 15.

A sorting hole 1 having a diameter smaller than the predetermined size of the food to be sorted is provided in the side surface 16 of the base of the rotating drum 10.
On the other hand, on the side surface 18 from the middle to the tip of the rotating drum 10, there are sorting holes 19, 19... having a diameter larger than the predetermined size of food.
is formed by drilling.

In FIG. 2, the axial and circumferential section-like lines shown on the side surface of the rotary drum 10 represent the arrangement of the screening holes 17 and 19 in a matrix for convenience of illustration.

Also, from the input port 11 of the rotating drum 10 to the discharge port 1

... are formed in the lower half of the base side, as shown in FIGS. 2 and 3, the small diameter screening holes 17, 1
7... A chute 5'' is attached to the frame 7 for food items smaller than a set size to be sorted from the group and dropped, and large diameter sorting holes 19, 19
...On the outside of the rotating drum 10 where the groups are perforated, the upper side edge is higher than the horizontal area, the lower side edge is lower than the horizontal area, and the rotating drum 10 is A concentrically formed guide plate 21 with a semicircular cross section has a large diameter sorting hole 19,1
9... They are arranged outside the group at a predetermined interval.

The predetermined interval is made equal to the diameter of each large-diameter screening hole 19.

Further, at one end of the lower side of the guide plate 21, there is a chute connected to a chute 5' connected to the next step such as bagging process at a position lower than the horizontal level of the rotating drum 10. 22 are integrally bent and connected.

As a result, a chute 2 is formed on the side edge of the guide plate 21 on the higher side of the rotating drum 10.

The large-diameter screening holes 19, 19... group are exposed in an open state and directly connected to the chute 22, and the portion of the group 9 underhangs and is lower than the horizontal level. For the upper side edge, each large-diameter screening hole 19 is connected to the guide plate 2.
1 means that he is blindfolded.

In Fig. 3, the sorted food 23 is shown as a circle for convenience of illustration, a standard size product is shown as one circle, and non-standard size products are shown as two or three circles. They are shown connected together.

In the above configuration, the squid material that has been cut for squid fritters is cut into predetermined dice sizes in a pre-process (not shown), sprinkled with flour or bread crumbs, etc. using a flour dusting machine, and then placed in a fryer. , pre-fried, frozen, and charged onto the chute 2 facing the input port 11 of the rotating drum 10 .

The frozen foods put into the chute 2 are of a predetermined size, and as described above, those smaller than the predetermined size are coated with flour, bread crumbs, etc. using a dusting machine, or are fried. In the process of being pre-fried, they stick to each other,
There are a small number of blocks that are connected to each other in the form of irregularly shaped large blocks and blocks that are not of the specified size.

Therefore, frozen foods containing a mixture of these substances are fed from the chute 2 into the rotating drum 10, but as described above, the rotating drum 10 is tilted downward at a predetermined angle. , it moves to the discharge port 12 on the front side through its gravity.

However, since the spiral baffle plates 20, 20... are disposed inside the rotating drum 10 as described above, the material is not discharged all at once toward the discharge port 12 in a short path, but while rotating. It is fed forward at a slow speed and is subjected to a sorting action during that time.

As described above, on the base side of the rotating rotary drum 10, there are a large number of small-diameter sorting holes 17, 17... groups on the circumferential surface, so that the frozen food 23 that is slowly fed forward is Items smaller than the set size are subjected to a sorting action and fall onto the chute 5'' and are discharged.

Next, as shown in FIG. 3, the food 23 that has passed through the group of small-diameter sorting holes 17, 17, etc. is either of a predetermined size for the food, or has been subjected to a flouring process using a flouring machine as described above, or , in the pre-flying process, two, three, and rarely four connected irregularly shaped large-sized lumps, which are part of the group of large-diameter screening holes 19, 19, etc. At this time, the lower half of the rotating drum 10 receives a sorting action.

That is, in this process, almost all the frozen foods 23 within the specified size range are selected from the group of large-diameter sorting holes 19, 19, etc., and are held between the guide plate 21. 3
In the state shown in the figure, the rotary drum 10 is rotated to the left to be lifted up, and in this process, the food 23 in the standard size range is lifted up by the side edge of the guide plate 21. Since it is directly connected to the chute 22, the rotary drum 1
Each large-diameter screening hole 19 of 0 will be opened,
Therefore, the food 23 within the standard size range is continuously discharged from the chute 22 to the next bagging process via the chute 5', as shown in FIG.

On the other hand, as shown in the figure, two or more connected blocks of irregular size have their tips partially exposed to the group of large-diameter screening holes 19, 19, etc., and come out of the guide plate 21. However, the center of gravity of the connected product will be located further inward, and therefore,
When the rotary drum 10 is lifted upward as it rotates, it rolls back into the rotary drum 10 and repeats this operation to form the spiral baffle plate 2.
0, 20, . . . and gradually moves to the discharge port 12 at the tip, where it is collected via a chute (not shown).

Therefore, only standard foods of a predetermined size are transferred to the next bagging process via the chute 22, 5' via a belt conveyor, etc., and as a result, the frozen food to be packed in bags is Only the standard products that meet the regulations are packed, ensuring that product accuracy is maintained.

It should be noted that the embodiment of this invention is of course not limited to the above-mentioned embodiment. For example, a curved portion may be provided inside each large-diameter sorting hole to facilitate discharge to the chute 22 of the next stage. In addition, various designs can be adopted in which the inclination angle of the rotating drum can be freely adjusted.

In addition, it is of course applicable not only to frozen food fritters and fries, but also to various foods such as diced and cut vegetables and fruits, as well as processed and heated foods. .

<Effects of the invention> According to this invention, basically, when sorting frozen foods into predetermined standard sizes before bagging, it is possible to separate foods smaller or larger than the standard size from foods within the standard size range. Needless to say, foods that become irregularly sized lumps due to the combination of two or more unit sizes during the processing process before the sorting process or the freezing process are also reliably excluded and processed according to the specified criteria. This provides an excellent functional effect of being able to sort out standard-sized foods.

Further, as described above, by providing the spiral baffle plate inside the rotating drum, the sorted food does not pass all at once towards the discharge port, but is stagnated and is effectively subjected to the sorting action.

By forming a large number of small diameter sorting holes for foods smaller than the set size at the base of the rotating drum, food smaller than the standard size is first sorted, and then large diameter holes within the set size range are sorted at the tip. An excellent effect can be achieved in that two-stage sorting can be performed in which items of standard size in the second stage are sorted in the sorting hole and transferred to the next stage process.

Further, the connected lump-like foods of irregular sizes that have not been sorted by the group of large-diameter sorting holes can be sent out from the distal end outlet.

Therefore, a guide plate having a semicircular cross section is provided concentrically on the rotating drum in an underhung manner with respect to the group of large-diameter screening holes at the tip, and is connected to the next stage at the side edge of the guide plate. By integrally providing the chute, and by forming an opening to the large diameter sorting hole of the rotating rotating drum between the lateral part of the rotating drum and the edge of the chute,
This has the effect that only standard-sized food is discharged from between the rotating drum and the guide plate to the next step.

On the other hand, even if the tip of the irregularly sized chunky food, in which at least two standard-sized foods are connected, is exposed to each large-diameter sorting hole group of the rotating rotary drum, the connected irregular-sized food As it rises while being held between the guide plates, the center of gravity is inside the rotating drum, so it is turned over again and falls inside, and this state is repeated until it is ejected to the next stage through the large-diameter sorting hole. This provides an excellent effect in that the liquid can be reliably discharged from the discharge port without any problems.

In addition, by undergoing the sorting action described above, at least two or more irregularly sized foods connected to each other will not be mixed into standard sized foods, so there will be no problem with foods with poor color or with clothes that are about to fall off. This has an excellent quality effect in that defective products do not enter the market, and the product value improves as a result.
