Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention provides an automatic method for automatically removing the head of a domestic animal such as a pig, which is separated from the carcass after slaughter, in order to utilize the cheeks and other meat present in the head. This relates to equipment for cleaning the equipment.

[Conventional technology]

In the past, the head meat of livestock such as pigs was not used much as waste meat, but because the meat contains an oil component different from that of the body, and has a unique taste, it has recently been used as meat such as pork siew mai, pork gyoza, etc. It has come to be used for a wide range of purposes. When using it, the head must be washed to remove foreign matter such as sludge that has adhered to it. In other words, heads sent from slaughterhouses are so dirty that they cannot be used as is. First, the hair on the surface of the head is removed using a device called a skinner, but hair entangled with the meat fibers and foreign matter such as dirt and sand stuck between the meat cannot be easily removed. Previously, the foreign objects had to be picked out completely by hand while pouring large amounts of water (approximately 2.5 liters per head).
Additionally, attempts have been made to remove the dust using a jet water stream and to collect dust using a dust vacuum cleaner.

[Problem to be solved by the invention]

When using the above-mentioned conventional cleaning methods, it is difficult to remove foreign substances to a satisfactory degree, and manual cleaning is not only inefficient, but also requires the use of a large amount of water. There is.

Therefore, the present invention has a simple structure and can satisfactorily wash the heads of livestock without using much water, thereby increasing the commercial value of livestock head meat. The purpose of the present invention is to provide a livestock head washing device that is capable of cleaning heads of livestock.

[Means to solve the problem]

In the present invention, a cleaning section having a supply port and an outlet is installed in the upper part of the water tank, and a rotary drum rotatably supported with its lower part immersed in water is provided in the cleaning section, and the The rotating drum is provided with a plurality of raking blades at regular intervals that protrude in the axial direction and extend from the supply port of the cleaning section to the front of the outlet, and further, delivery blades are provided protruding from a portion of the rotating drum corresponding to the outlet, Further, a livestock head washing device is provided in which the washing section is provided with a partition plate that extends below the rotating drum and partitions the inside of the water tank, and a foreign matter collection port is provided in the top surface of the device and the box-shaped main body case. , above it,
The above-mentioned problems have been solved by a livestock head washing device comprising a brushing device formed by rotatably supporting a brush drum having a large number of brushes installed on its circumferential surface.

[Effect]

The head of the livestock fed through the supply port continues to turn over as the rotating drum rotates and heads toward the outlet. At that time, the rake blades that come into contact with the head of the livestock,
The surface of the livestock's head is washed by being rubbed with water. The cleaned head of the livestock is thrown up by the delivery wing and taken out from the outlet. In a brushing device, the meat of a livestock head is brushed with a brush to finish the meat.

〔Example〕

Preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an overall external view of the apparatus according to the present invention. In the figure, 1 is a water tank, and 2 is a cleaning section installed above the water tank 1. The washing section 2 is provided with a supply port 3 for supplying the pig's head and an outlet 4 for discharging the washed pig's head. Supply port 3
A pedestal 5 is usually provided to facilitate feeding of the pig's head. A rotating drum 6 as described later is provided within the cleaning section 2.

Figures 2 and 3 show the internal structure of this device.A suitable amount of water is placed in the water tank 1.
Further, a partition plate 7 is installed between the washing section 2 and the washing section 2 . The rotating drum 6 of the cleaning section 2 is installed from the supply port 3 to the outlet 4 so that the supply port 3 side is slightly higher than the outlet 4 side, with its lower part immersed in water. The rotating drum 6 includes a plurality of scraping blades 8 that protrude radially at regular intervals. The tip of the scraping blade 8 is bent by about 45 degrees in the rotational direction of the rotary drum 6. Each scraping blade 8 extends from the end of the rotary drum 6 on the side of the supply port 3 to just before the outlet 4 (see FIG. 3). The scraping blade 8 is usually made of a long material, but may be made of a series of short materials, as shown by reference numeral 8a in FIG. 4. A short delivery blade 9 having the same shape as the scraping blade 8 is usually provided protruding from a portion of the rotating drum 6 facing the outlet 4 . The rotating drum 6 may also be tapered. 10 is a motor that rotationally drives the rotating drum 6. In addition,
11 in FIG. 2 indicates the pig's head.

In the above-described apparatus, while rotating the rotary drum 6, the pork head meat 11 is fed through the supply port 3 manually or by mechanical means such as a conveyor. The introduced pork head meat 11 is scraped up by the scraping blades 8 rotating from below, rolls irregularly in the washing section 2, and gradually moves to the outlet 4 side as the rotating drum 6 tilts. Head to. During this process, the circumferential surface of the pork head meat 11 is rubbed by the scraping blades 8, and the sludge, gravel, hair, etc. adhering to the circumferential surface are forced into contact with the inner wall of the washing section 2 or the partition plate 7, etc. removed. At this time, since the lower part of the rotating drum 6 is immersed in water, water is removed from the pig's head 11 by the scraping blades 8 as it rotates.
The foreign matter is thrown up toward the surface to facilitate removal of the foreign matter and to perform cleaning. The water in the tank 1 is partitioned by a partition plate 7, and the water does not circulate throughout the tank 1. Therefore, the scraped sludge, fallen teeth, etc. settle on the bottom of the water tank 1 and do not float, making the water less likely to become contaminated.
Can be used for cleaning without waste. As for the amount of water required for washing, one ounce of water per pig's head is sufficient. The pig's head 11 that has been cleaned reaches the end of the rotary drum 6 and is thrown up by the delivery blades 9 and delivered from the outlet 4.

Most of the sludge and the like are removed by the above treatment, but since the scraping blades 8 do not reach sunken areas such as eyes and ears, preferably a second treatment is further performed. FIGS. 5 and 6 show an example of the configuration of a brushing device for performing the second process. In the figures, reference numeral 12 denotes a brush drum, and a large number of brushes 13 are installed on the circumferential surface of the brush drum. It is preferable that the brushes 13 are arranged irregularly. For example, when arranging 5 in a horizontal row, the first row has 2 on both sides, the 2nd row has 3 on the inside, the 3rd row has 2 on both sides and the center, and so on. Change the arrangement depending on the column you want to use.
By doing so, the brush 13 is connected to the pig's head 11.
The foreign matter removal process can be performed evenly and in a good condition by avoiding hitting only the same position on each part and hitting each part evenly and with varying degrees of strength. The brush 13 is made by bundling thin rods 14 made of polypropylene, for example, and inserting them into a metal tube 15, but it is preferable that the lengths of the thin rods 14 are different as shown in FIG. In this way, the contact pressure of the tip of the brush 13 can be made more or less strong, making it easier for the tip of the brush to reach deep into the hollow of the pig's head. The bundle of thin rods 14 is preferably prevented from slipping out of the metal tube 15 by heating and melting the lower ends to form an enlarged portion 16 . To fix the brush 13 to the brush drum 12, for example, the brush 13 may be exposed from the inside of the brush drum 12, and the exposed portion of the metal tube 15 may be crushed (see imaginary line in FIG. 7). 17 is
It is an angle member that pivotally supports the brush drum 12 on the main body case 18, and 19 is a motor that rotationally drives the brush drum 12. The body case 18 is used to collect scraped foreign matter, and a foreign matter collection port 20 is provided below the brush drum 12 on its top surface, and the top surface of the main body case 18 descends toward the foreign matter collection port 20. It is sloping. A hood 21 is installed at the upper end of the main body case 18 so as to cover the brush drum 12.

In this brushing device, the main body case 1
The pig's head 11 supplied onto the upper surface of the pig head 8 is pressed down with both hands by the operator or mechanically pressed against the brush group. The group of brushes rotates in a direction (in the direction of the arrow in FIG. 6) that draws the pig's head 11 between the brush group and the top surface of the main body case 18, and by coming into contact with the pig's head 11, removes foreign matter attached thereto. Scrape off.
Since the brushes 13 are arranged irregularly as described above, various parts of the pig's head can be cleaned evenly, and the scraped foreign matter falls from the foreign matter collection port 20 and is collected in the main body case 18. Ru. The pig's head 11 is rotated as appropriate to change the part to be treated.

This brushing device may be separate from the above-mentioned cleaning device, and the pig head 11 coming out of the outlet 4 of the cleaning device may be transported to the brushing device manually or by using a conveyor or the like. It is also possible to integrate both devices by attaching a brush near the outlet 4 so that the pig head 11 coming out of the outlet 4 immediately goes to the brush 13.

〔Effect of the invention〕

As described above, the present invention has a simple structure and can reliably and efficiently wash the heads of livestock such as pigs without using a large amount of water as in conventional methods. This has the effect of expanding the supply of livestock such as pigs with unique flavors, thereby increasing the scope and value of their use.
