Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an apparatus for immersing a layered body of poultry in cold water and cooling it while conveying it together with the cold water. The present invention relates to a cooling conveyance device that is installed in a waterway and rotates the screw blades around an axis to promote water flow and convey a layered body together with the water flow.

[Prior Art] This type of cooling conveyance device is called a screw chiller or a spiral chiller, and FIG. 3 is a partially cutaway perspective view schematically depicting a conventional example.

A waterway is constituted by a half-cylindrical water tank 1.

W indicates the water surface. A helical screw blade 2 is provided in it, and while rotating it as shown by arrow A, a layer is introduced as shown by arrow B, cold water is also injected, and ice blocks are added if necessary.

The injected cold water and the layered body are conveyed in the direction of arrow C by the screw blades 2, and the layered body is stirred and cooled in the cold water.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional screw chiller, (a) the layered bodies are conveyed while floating up and down in the cold water, resulting in poor cooling efficiency; Easy to cause uneven cooling.

((I) A large number of layers may float together in one place, and the torque required to drive the screw blades is large.

In addition, the one-layer structure is easily damaged by strong finger contact with the screw blades.

(c) Since the waterway is open, it is not possible to carry out treatments such as disinfection using a transporting and cooling gas (for example, ozone) at the same time. Furthermore, if the screw blades are rotated quickly, the water 114 will scatter, worsening the working environment.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to ensure that the entire surface of the layer is in good contact with cold water, and that high efficiency is achieved without causing uneven cooling. (b) The large number of layered bodies do not overlap), the resistance to the screw blades is low and the required driving force is small, (c) there is no risk of damage to the 0M body, ( d) A cooling and transporting device for poultry that is suitable for parallel processing with gas, and (e) There is no risk of water droplets being scattered even when the screw blades are rotated at high speed, and is suitable for maintaining a working environment. This is what we are trying to provide.

[Means for solving the problems] In order to achieve the above object, the cooling conveyance device of the present invention has the following features:
A spiral screw is rotated in the waterway to promote water flow,
In a device that transports and cools the layered layer of poultry with a water flow, most of the water channel has a right cylindrical shape concentric with the screw blade, and the water level within the right cylindrical portion It is characterized by filling the inside of a right cylindrical part. Majority of the above shall mean at least half of the length of the watercourse.

[Function] According to the above-mentioned configuration, most of the waterway (1/2 or more) is sealed in a cylindrical shape, and since this cylindrical space is filled with water, the layered body is completely submerged in the water without floating or sinking. Retained. (a) This allows for highly efficient cooling with even cooling, (
b) Since the layers do not gather and float, the screw blades do not receive uneven resistance, the required driving force is small, and (c
) Since the layers do not gather and float, they are transported smoothly,
There is no risk of damage; (d) most of the waterway is sealed, making it suitable for simultaneous gas treatment; and (e) most of the waterway is sealed, so water droplets do not occur even when the screw blades are rotated at high speed. does not scatter.

Embodiment FIG. 1 is a vertical sectional view schematically depicting an embodiment of the present invention, and FIG. 2 is a plan view.

Reference numeral 3 denotes a cylindrical waterway, and most of its length (approximately 475 mm in this example) is constituted by a right cylindrical portion 3a, and its upstream end (right end in this example) connects to the large diameter portion 3 through a tapered portion 3b.
connected to c.

4 is a screw blade, the central axis of which is constituted by a hollow shaft 4a. The right end portion 4b is configured to have a large diameter corresponding to the tapered cylindrical portion 3b+large diameter cylindrical portion 3°.

An input port 5 for the layered body is provided on the top surface of the large diameter portion 3°. The downstream end (left end in the figure) of the right cylindrical portion 3a opens into the water tank 7.

8 is a scraping conveyor installed in the water tank 7.

A water supply port 9a is provided in the large diameter portion 3c of the double water channel, and a drain port 9b is provided in the water tank 7, and cold water flows from the right to the left in the figure. The screw blades 4 are rotationally driven in a direction that promotes the water flow.

The large diameter portion 3° of the water channel is equipped with a water level control means 10, which controls the water level W' to the inside of the tapered portion 3b to fill the right cylindrical portion 3a with water.

Bearings 11a and oh are provided near both ends of the hollow shaft 4a, and rotatably support the hollow shaft. No bearing is provided near the center of the hollow shaft 4a.

Since this hollow shaft 4a is held underwater and receives μ force,
Even if the central portion is not held, the central portion does not tend to sag downward. Therefore, there is no risk that the central bearing (not provided) will impede the water flow or hinder the conveyance of the m bodies.

The large-diameter portion 3c of the cylindrical waterway 3 is provided with an input port 5, and since it has a large diameter, it is easy to input m ice cubes (or ice cubes if necessary).

The m bodies sent to the left side of the figure along with cold water are discharged into a water tank 7 and carried out by a scraping conveyor 8.

Since the inside of the right cylindrical portion 3a is filled with cold water, the entire surface of the m bodies being conveyed therein comes into contact with the cold water.

Therefore, the m-body is cooled with high efficiency without uneven cooling.

In addition, since the m bodies are completely immersed in the cold water, they are transported while being uniformly dispersed in the cold water flow, without collecting and floating in one place. As a result of this uniform dispersion, the conveyance is carried out smoothly, and the screw blades are not subjected to uneven resistance, so the required power is small, and there is no risk of damage to the m-body.

[Effects of the Invention] As detailed above, according to the cooling conveyance device of the present invention, (a) the entire surface of the 0-layer body is brought into good contact with cold water, and is cooled with high efficiency without causing uneven cooling. , (b), a large number of m
The bodies do not gather together and float, and the required driving force is small because there is little resistance on the screw blades. (C) There is no risk of damage to the 0-layer body, and (d) Processing with gas proceeds in parallel. (e) Even if one 9-screw blade is rotated at high speed, there is no risk of water droplets being scattered, which is an excellent practical effect.
