Description

[Detailed description of the invention] (Field of industrial application) This invention relates to the proposal of a freezing device suitable for continuously freezing fresh foods, frozen confectionery, etc.

(Prior art) Conventionally, when freezing vegetables, marine products, processed foods, ice cream, etc. to maintain freshness or for frozen preservation, freezing has been used when large quantities need to be processed continuously. A facility called a tunnel is used. In this method, a belt conveyor is disposed inside a relatively long tunnel-shaped closed chamber, and while the frozen object is placed on the belt conveyor and transferred, a refrigerant is passed through the closed chamber. It is now possible to freeze it.

(Problems to be Solved by the Invention) Although the conventional equipment described above serves the purpose of continuously freezing objects to be frozen, it requires a relatively large installation area, and is therefore limited in installation location. It has been pointed out that the drawback is that the worker is highly fatigued as a result of imposing a considerable amount of exercise on the worker during the work. In addition, since the refrigerant must be distributed through a relatively long tunnel, it is necessary to distribute a considerable amount of refrigerant in order to increase the refrigeration effect, and improvements in this respect are desired from an economic standpoint. This is the current situation.

(Means for solving the problem) This invention is based on an almost endless chain that is wound around each pair of sprocket wheels that are supported at the top and bottom of a tower-shaped insulated chamber into which refrigerant is supplied from a suitable refrigerant generation source. Protruding arms are installed at regular intervals,
Between a pair of opposing arms, a bucket arm extending upward from the bucket is supported between bucket pins projecting left and right from these arms;
A rotating pin is supported at the lower end of the bucket steady rest fixed to the bucket pin parallel to the bucket arm, and a roller holder with the rotating pin attached to the center is provided with rollers at positions symmetrical to the rotating pin. Provided is a three-dimensional refrigeration device, characterized in that the rollers are supported rotatably, and these rollers are guided by sandwiching guide rails arranged at a constant distance from the endless chain from both sides. As a result, we succeeded in realizing a refrigeration system that can significantly reduce the installation area compared to conventional refrigeration tunnels, has high refrigeration efficiency, and has improved workability.

(effect) Next, this invention will be explained in detail with reference to the drawings.

First, in FIGS. 1 and 2, 1 is a tower-shaped heat insulating chamber, and a heat insulating layer 2 is formed on its outer wall. A refrigerator compartment 3 is located on the side of the heat insulation compartment 1.
A refrigerator, a heat exchanger, a fan, etc. are installed in this refrigerator room 3, and constitute a refrigerant generation source that circulates the refrigerant in the heat insulation room 1. Low-temperature air is generally used as the refrigerant, but this does not preclude the use of other refrigerants.

A pair of sprocket wheels 4, 4, 5, 5 are supported above and below the heat insulating chamber 1, and endless chains 6, 6 are wound around these sprocket wheels 4, 4, 5, 5, respectively. Bucket carts 7 are supported at approximately constant intervals on the endless chains 6, 6, which are driven in circulation via an appropriate drive source (not shown), and the details thereof will be explained with reference to FIGS. 3 to 5.

Although only the mechanism attached to one of the endless chains 6, 6 is shown in these FIGS. 3 to 5, a similar mechanism is provided on the other side, and for the sake of simplification of illustration and explanation. , only one will be explained.

A bucket pin 9 is provided at the free end of the arm 8 that projects laterally from the endless chain 6 to project left and right in a direction orthogonal to the arm 8. At the same time, a bucket rest 11 is fixed in parallel to the bucket arm 10 on the opposite side of the bucket pin 9, and a rotation pin 12 is supported at the lower end of this bucket rest 11, so that the rotation A roller holder 13 with a pin 12 attached to the center rotatably supports rollers 14 and 15 at symmetrical positions with respect to the rotating pin 12, and these rollers 14 and 15 are spaced apart from the endless chain 6 at a constant interval. It is designed to be guided by sandwiching guide rails 16 from both sides.

In the above configuration, when objects to be frozen are appropriately placed on each bucket 7 in the heat insulating chamber 1 in which the refrigerant sent from the refrigerant generation source is circulated, and the endless chain 6 is driven to circulate, as shown in FIGS. In Fig. 7, when the bucket cart 7, which was at position A, moves to position B, the rollers 14 and 15 are curved around the guide rail 16 and are inclined with respect to the horizontal plane, sandwiching the guide rail 16. However, since the rotating pin 12 rotates exactly at the center between the rollers 14 and 15, the bucket steady rest 11 does not lose its vertical state, and therefore, it is integral with the bucket steady rest 11. Summer Bucket 7
is also held horizontally. In this way, the bucket 7 is maintained horizontally at each stage of the circulation drive of the endless chain 6 thereafter.

Returning to FIGS. 1 and 2, 17 indicates the loading port for the frozen material, and 18 indicates the unloading port, but in the case of this invention, the circulation drive direction of the endless chain 6 is reversible. Therefore, the loading port 17 and the unloading port 18 may be reversed. Further, depending on the location conditions of the installation site and requests for improved heat insulation, the heat insulation room 1 can be made semi-underground as shown in the figure, or it can be installed entirely above ground.

(Effect of the invention) According to this invention, since it has the above-mentioned structure,
This has the following effects. In other words, because it has a three-dimensional structure, it can be installed even in places with limited installation space, making it economical.

Continuous operation with vertical drive is efficient.

Since the convection efficiency of the refrigerant is good, freezing work can be done quickly.

Because it has a rotary structure with an endless chain,
Forward rotation and reverse rotation can be freely selected.

Because the object to be frozen is kept horizontally during transfer,
There is no damage to the product.
