Description

[Detailed description of the device]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for rapidly cooling a carcass, and more particularly to a device for cooling a carcass of a chicken.

[Prior art]

Immediately after being slaughtered, the body temperature of chickens is as high as 40 ° C. After slaughter, it must be cooled to prevent alteration. If the cooling takes time, the quality of the chicken carcass will be significantly reduced. The most commonly practiced in the past is to put chickens in an aquarium in which water and ice are mixed. In this method, the chicken is shaken and moved in a certain direction to be cooled. However, this method has a drawback in that all chickens cannot be cooled in a state of being washed with fresh water, and all chickens cannot be cooled uniformly and quickly at low temperature, so that the cooling temperature easily varies. Further, as a cooling device, a device has been developed in which a carcass of a chicken is placed on a belt conveyor, moved in a certain direction, and cold water is showered on the carcass.

[Problems to be solved by the device]

However, the cooling device with this structure has a drawback that thermal efficiency, that is, the amount of heat taken by a unit amount of cold water from the chicken is small, and the running cost is considerably higher than that of the one in which the carcass of the chicken is immersed in cold water. is there. Further, since it is cooled with shower water, there is a drawback that it takes time to completely cool the inside. In order to solve these drawbacks of the conventional cooling device, a device for cooling a chicken carcass having the structure shown in FIG. 6 has been developed. This device circulates cold water in an elongated running water gutter 1. In the running water gutter 1, in the direction opposite to the flow of cold water,
The dam 2 is used to slowly move the carcass of the chicken.
This device is usually designed to have a total length of about 10 meters and a width of about 3 meters so that a large number of chickens can be processed at one time. This device has a feature that foreign substances attached to the surface of the chicken carcass can be washed while the carcass of the chicken is moved in the direction opposite to the direction of running water.
The foreign matter separated from the carcass of the chicken floats on the surface of the water. Foreign matter on the surface of the water reattaches to the carcass during its movement. Therefore,
Water suspension should be removed as soon as possible.
When foreign matter on the water surface is removed, a cleanly washed carcass can be obtained. Not only does the washed carcass look beautiful, but the amount of bacteria etc. attached is reduced, and it becomes a hygienic carcass of high quality. The present invention provides a carcass cooling device that can obtain a cleanly cleaned carcass and can cool it quickly.

[Means for solving the problem]

The carcass cooling device of the present invention has the following configuration to achieve the above-mentioned object. The carcass cooling device has a running gutter (1) horizontally or almost horizontally arranged in the form of an elongated gutter, and cold water is sucked from one end of the running gutter (1) to cool the sucked cold water. Cold water circulating means 4 for cooling and supplying to the other end of the running water gutter to chill the running water in a certain direction, and a carcass in a direction opposite to the flowing direction of the cold water supplied by the cold water circulating means. Means for moving the carcass. Further, in the carcass cooling device, a means for removing suspended matter floating on the cold water surface of the running water gutter is arranged at one end of the running water gutter and on the side where the cold water circulating means sucks the cold water. By the way, the carcass cooling device of the present invention can be most conveniently used for chicken carcasses. Therefore, the carcass will be described below as a chicken carcass. However, it goes without saying that this invention is not limited to carcasses of chickens and can be used for carcasses other than chicken carcasses.

[Preferred embodiment]

An embodiment of the present invention will be described below with reference to the drawings. However, the embodiments shown below exemplify a device for embodying the technical idea of the present invention, and the device of the present invention has the following materials, shapes, structures, and arrangements of components. Not specific. The device of this invention is subject to various modifications within the scope of the claims for utility model registration. Further, in this specification, in order to facilitate understanding of the scope of claims for utility model registration, the numbers corresponding to the members shown in the embodiment are
It is added to the members shown in the "column for claim for utility model", "column for means for solving conventional problems" and "column for action". However, the members shown in the scope of claims for utility model registration are by no means limited to the members of the embodiment. The chicken cooling device shown in FIG. 1 comprises a running water gutter 1, a cold water circulating means 4, a moving means, and a removing means. The running water gutter 1 is formed in an elongated gutter shape so that a carcass can be transferred here, cooled, and washed. This running gutter 1
As shown in FIG. 3, the cross-sectional shape is U-shaped. The total length of the running water gutter 1 is determined in consideration of the amount of cooling water to be filled, the flow velocity, the number of chickens cooled in a unit time, and the like.
Generally, the carcass supplied at the right end is tens of minutes to 2
Since it takes about a time to send it to the right end and cools it, the total length is determined to be several meters to several tens of meters, preferably about 10 m, and its width is determined to be, for example, about 1 m to 5 m. A jet member 5 is provided at the bottom of the running water gutter 1 so as to extend in the longitudinal direction. The innumerable bubbles blown out from the fume member 5 into the water stir the cooling water to quickly cool the chicken carcass.
Further, the bubbles floating in the water float the foreign matter contained in the water on the water surface, and facilitate the separation at the left end of the running water gutter 1. In addition, the bubbles generate ultrasonic waves when they burst in water.
The ultrasonic wave cleans the carcass of the chicken ultrasonically. The fumarolic member 5 is composed of a pipe having innumerable small holes. The pipe is connected to a blower or a compressor, is supplied with pressurized air, and ejects bubbles from the small holes. The cold water circulation means 4 supplies cold water to the running water gutter 1. The cold water circulation means 4 includes a cooler 4A for cooling the water and a running water gutter 1 for the cold water.
It has a supply pump 4B for supplying to. The cooler 4A makes the water supplied to the running water gutter 1 close to 0 ° C., for example. Cooler 4A
The cold water cooled by is supplied to the running water gutter 1 by the supply pump 4B. The cold water discharged from the running water gutter 1 is circulated and reused. Therefore, the drainage port 3 provided at the left end of the running water gutter 1
Is connected to the suction side of the cold water circulation means 4. That is, the circulation pipe connected to the drainage port 3 is branched into two, one is connected to the cold water circulation means 4 and the other branch is connected to the drainage valve 10. The suction side of the cold water circulation means 4 is connected to the drain port of the running water gutter 1 via a filter 11. The filter 11 filters foreign matter contained in cold water to clarify it. The device having this structure drains a part of the cold water drained from the running water gutter 1 and circulates and reuses the remaining part of the cold water. For example, 20 to 70% of the cold water discharged from the running water gutter 1 is discharged to the outside, and the remaining cold water is circulated. The amount of water corresponding to the amount of drainage is supplied to the suction side of the cold water circulation means 4. The amount of cold water supplied by the cold water circulation means 4 to the running water gutter 1 is
It is adjusted according to the throughput of the carcass per hour. With a high carcass supply, cold water is warmed in the carcass. Therefore, the more the carcass processing capacity is, the more the cold water supply amount is increased. For cold water, water near 0 ℃ is supplied to the running water gutter 1 and the carcass is
40 ° C chickens at 4 ° C before being transferred from end to end
The amount of water that can be cooled is decided. The means for removing floating substances floating on the water surface of the running water gutter 1 is for removing the water surface floating substances that have been transferred to cold water and collected on the discharge side of the running water gutter 1. It is arranged at the left end of the running water gutter 1. As shown in FIG. 2, the removing means includes a discharging member 6 for foreign matter floating on the water surface, an endless chain 8 for driving the discharging member 6, and a chain wheel 7 for driving the endless chain 8.
And a motor 9 for rotating the chain wheel 7. The discharge member 6 shown in the front view of FIG. 5 and the plan view of FIG.
Is made in a plate shape as a whole. However, the discharge member 6 does not necessarily have to be plate-shaped, and may be molded into a cup shape, for example. As shown in FIG. 4, both sides of the plate-shaped discharging member 6 are gently bent forward, and a rubber-like elastic plate is fixed to the lower end as shown in FIG. The discharge member 6 is connected to the endless chain 8 at regular intervals. The endless chain 8 is hung on the chain wheel 7. The chain wheel 7 is attached to the upper surfaces of the side walls on both sides of the running water gutter 1 via a bearing and a frame.
The chain wheel 7 has a chain that is hung on it.
Move the running water gutter 1 in the lateral direction. Therefore, the rotation axis of the chain wheel 7 is extended in the horizontal direction and supported. Further, as shown in FIG. 2, this rotating shaft is extended and supported in the carcass transfer direction of the running water gutter 1. Furthermore, the chain wheel 7 is connected to the endless chain 8 that moves downward so that the discharge member 6 can move on the water surface and discharge floating substances on the water surface.
However, it is adjusted to a position where it moves near the water surface of the running water gutter 1. The chain wheel 7 is connected to a motor 9 and rotated. In the removing means shown in FIG. 2, the discharging member 6 moved by the lower endless chain 8 moves along the chain guide 12.
The chain guide 12 is fixed to the frame in a posture in which both sides have an upward slope and the middle is horizontal. The endless chain 8 that moves along the horizontal portion in the middle of the chain guide lowers the lower portion of the dam plate 2 below the water surface. In the removing means shown in FIG. 2, the discharge member 6 moves from the right to the left and discharges the water surface suspended matter to the outside of the running water gutter 1. Therefore, below the chain guide 12, the chain guide
An inclined plate 13 is fixed in parallel with the gradient of 12. Inclined plate
13, the lower end of the discharge member 6 moves along this upper surface,
Scrape the floating material out of the running water gutter 1. The inclined plate 13 extends from the water surface to a height exceeding the partition of the running water gutter 1.
The distance between the inclined plate 13 and the chain guide 12 is adjusted to be slightly lower than the height of the discharge member 6. In the inclined plate having this structure, the rubber-like elastic body at the lower end of the discharging member 6 is slightly deformed and rises while rubbing the upper surface.
Therefore, the discharge member 6 can discharge the scooped water surface suspended matter without leaking. However, the carcass cooling device of the present invention does not necessarily require the inclined plate 13
Need not be provided. Although not shown, if a cup-shaped discharge member is used, the discharge member can discharge the scooped water surface suspended matter to the outside of the running water gutter without using an inclined plate. The moving means includes a weir plate 2 and a moving member that moves the weir plate 2 along the running water gutter 1. The dam plate 2 moves the carcass fed into the running water gutter 1 from the left end to the right end in FIG. 1 in the direction opposite to the flowing direction of the cooling water. A plurality of weir plates 2 are arranged in parallel to each other at a distance of, for example, several tens of cm to 1.5 m and oriented laterally with respect to the running water gutter 1. Both ends of the barrier plate 2 are rotatably attached to a chain 14 as a moving member in a vertical plane. Each weir board 2 has a running water whose water can pass but a chicken cannot pass so that it can move in cooling water along the running water gutter 1 and can move the carcass, and its outer shape is running water. It is formed in a plate shape slightly smaller than the inner shape of the gutter 1. The weir plate 2 shown in FIG. 3 is formed in a lattice shape on one side and has water permeability only on one side. Barrier plates 2 that are adjacently connected to the chain 14 are formed in a grid pattern on opposite sides. The dam plate 2 of this structure forms a zigzag water channel in the running water gutter 1 to lengthen a substantial running channel of cold water. The moving member includes two chains 14 stretched on both sides of the running water gutter 1, a sprocket shaft 15, a reduction motor,
It is composed of a guide rail 17 and a mover 18. The chains 14 are hung on sprocket shafts 15 arranged at both ends of the running water gutter 1 so that they can be moved at the same speed and in the same direction. The chain 14 slides along the upper edge of the running water gutter 1 to move the dam plate 2 fixed thereto. The sprocket shaft 15 has a chain wheel fixed to both ends of the shaft on which the chain 14 is hung. Sprocket shaft
There are two 15s, which are horizontally supported at both ends of the running water gutter 1. The distance between the chain wheels fixed at both ends of the shaft is
It is adjusted to the width of the running water gutter 1. The chain 14 hung on the chain wheel moves along the upper edge of the running water gutter 1 as shown in FIG. Therefore sprocket shaft 15
Are horizontally supported by extending in a direction orthogonal to the running water gutter 1, that is, extending horizontally. Although not shown, the deceleration motor slowly rotates the sprocket shaft 15 and, via the chain 14, the dam plate 2 of the running water gutter 1.
Are moved from left to right in FIG. As shown in FIG. 1 and FIG. 3, the guide rail 17 is separated from the upper edge of the running water gutter 1 by a predetermined distance and is stretched in parallel with the upper edge of the running water gutter 1. The roller of the mover 18 rolls along this lower surface, so that the dam plate 2 moving in the running water gutter 1 is held vertically or almost vertically. As shown in FIG. 3, the mover 18 pushes the downward motion of the dam plate 2 forward by the roller moving along the lower surface of the guide rail 17, and holds the dam plate 2 vertically to advance it. As described above, the roller is provided at a position slightly displaced rearward from the position where the chain 14 is pivotally attached to the barrier plate 2. The dam plate 2 moving into the running water gutter 1 is advanced by the chain 14 and held vertically by the mover 18 and the guide rail 17. The weir plate 2 that has passed through the running water gutter 1 and moved to the extraction side of the carcass (the right end of the running water gutter 1 in FIG. 1) is lifted from the running water gutter 1 and then passes through the running gutter 1. The top of the plate 2
In the figure, it moves from right to left, that is, from the take-out side of the chicken toward the supply side and circulates. At this time, the barrier plate 2 is horizontally laid down and transferred by its own weight. Therefore, the dam plate 2 that returns and moves in the opposite direction above the dam plate 2 that moves in the running water gutter 1 is not vertically held by the mover 18, but is laid down horizontally by its own weight. Therefore, the guide rail 17 is not arranged along the chain 14 that returns. As shown in FIG. 1, the returning chain 14 moves on the chain guide 12 stretched on the returning path of the chain 14. The weir plate 2 that has been laid horizontally is also placed on the chain guide 12 and moved horizontally. In the right part of FIG. 1, the withdrawal position of the weir plate 2 that has passed through the running water gutter 1 is shown. The guide rail 17 moves the lower part of the weir plate 2 slightly forward at the take-out side end in the running water gutter 1 to push out the chicken, so that the end part of the guide rail 17 descends slightly downward toward the end. After being folded, it is folded upward. When the roller of the mover 18 moves on the lower surface of the guide rail 17 having a downward slope, the lower part of the dam plate 2 is pushed forward. After that, when the roller of the mover 18 moves up and moves along the lower surface of the slope portion, the barrier plate 2 is gradually erected vertically, and when it is further lifted up by the chain 14, it is horizontally laid down and placed on the chain guide 12. Will be moved. A chicken take-out member 16 is arranged at the end of the running water gutter 1. The take-out member 16 has radially extending blades on its outer periphery, which are slowly rotated by a reduction motor 19 to scrape chicken carcasses in the running water gutter 1 with the blades. As shown in FIG. 1, the weir plate 2 that has been moved to the carcass supply side at the left end of the running water gutter 1 is guided slowly into the rear running water gutter 1. The rotation of the barrier plate 2 in the vertical plane is braked by the guide rail 17. The guide rail 17, as shown in FIG. 1,
At the left end of the running water gutter 1, a part is bent upward, and then the end is further curved upward through a horizontal portion. When the roller of the mover 18 rolls along the upward curved portion of the end of the guide rail 17, the dam plate 2 is gradually raised from its horizontal position by its own weight, and when the roller moves to the U-curve part, the dam plate 2 2 is rotated vertically. The roller coming out of the U-bend is a guide rail stretched in parallel with the upper edge of the running water gutter 1.
17 Move along the lower surface to hold the dam plate 2 vertically.

[Effect of device]

The carcass cooling device of the present invention is capable of efficiently cooling the carcass and has the feature that the carcass can be cleaned and discharged cleanly. It is because the carcass cooling device of the present invention allows cold water to flow in a certain direction to the running water trough by means of cold water circulation means and moves the carcass in the direction opposite to the flowing direction of the cold water, and further, one end of the running water gutter. The cold water circulating means is realized by a unique structure in which the means for removing suspended solids is arranged on the side that sucks in cold water, that is, the side that supplies the carcass. The device that cools and discharges the carcass in this state can make the discharge side of the carcass the cleanest cold water area, and further, such as blades and oil separated from the carcass transferred by running water gutter. The suspended matter does not flow to the carcass in the opposite direction and reattach to the carcass on the discharge side. For this reason, the carcass discharged from the running water gutter has a characteristic that it can be treated in a sanitary manner with a very clean amount of bacteria attached and the like. In addition, the carcass cooling device of the present invention reduces the contamination of the cold water circulation means, improves the thermal efficiency, and realizes the features.
This is because the cold water circulation means removes floating matter at the portion where the cold water is sucked in, and the cold water from which the floating matter is removed is sucked in by the cold water circulation means and circulated in the running water gutter. When water surface suspended matters such as bird feathers and oil are mixed in the cold water sucked into the cold water circulation means, the thermal efficiency of the cold water circulation means is significantly reduced. In particular, since the water suspended matter contains bird's oil component, if this is sucked into the heat exchanger of the cold water circulation means together with foreign matter such as blades and dust, the heat exchange efficiency of the heat exchanger will be significantly reduced. There is a harmful effect. The reason is that the oil component attaches and accumulates floating matters such as blades and dust to the cold water passage of the heat exchanger. Since the device of the present invention is provided with a means for removing suspended matter that cleans and discharges the carcass, this removing means has a feature that it can be used in combination with a member for preventing a decrease in thermal efficiency of the cold water circulation means. A carcass cooling device that has high cooling efficiency and is capable of removing all suspended solids has the feature that it can clean the carcass with a small amount of cold water consumption. When cleaning and cooling the carcass cleanly with conventional equipment, increase the amount of cold water supplied to the running water gutter,
It was necessary to overflow a large amount of cold water from the discharge side. Therefore, there are drawbacks that the water consumption increases and the power consumption of the refrigerator increases. The reason is that a large amount of tap water or the like cooled from room temperature to near zero degrees Celsius is supplied to the running water gutter. Since the carcass cooling device of the present invention circulates the cold water from which suspended solids have been circulated through the cold water circulation means, it is not necessary to overflow a large amount of cold water even though the carcass can be washed and discharged cleanly. It also realizes the feature that the power consumption of the refrigerator can be reduced by reducing the amount of cold water consumed.
