Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a cooling device for rapidly cooling (including freezing) food and the like.

[Prior art]

A conventional device of this type is shown in FIG. In the figure, (1) is the object to be cooled such as surimi, (2) is (1)
(3) is a low-temperature container that holds frozen bread between the top and bottom. (5) is an inlet pipe for introducing the low temperature cooling fluid (9), and (6) is also an outlet pipe. (4) is the above fil
A flexible tube connects 1tll and (3), and the low temperature cooling fluid (9) is connected so as not to leak. (8) is a weighting device that presses the frozen pan (2) against the lower fixed bed 171 in order to enhance the effect of cooling the object (2) to be cooled from above and below with the low temperature fluid (9).

Next, the operation will be explained.

The object to be cooled (11 kg of frozen bread (2)) is manually inserted between the low temperature containers +3.

When the insertion is completed, a load is applied to the weighting device (8), and the flexible tube (4) is displaced to move the frozen pan (2) toward the fixed bed +71.
Insert completely.

Thereafter, the low-temperature cooling fluid (9) fed by a liquid feeder (not shown) sequentially flows through the inlet pipe +51, the low iris container (3), the outlet pipe (6), and the object to be cooled (1). When cooling is completed, the load is loosened and the frozen bread is again carried out manually.

After that, a heating device (not shown) is used to cool the object (1
) The frozen bread 2) is depanned and sent to the next process.

Since the conventional device is constructed as described above, it has the following deficiencies.

(1) Is it a huge amount of human effort for the phantom loading and unloading of frozen bread? It takes.

(2) Since the frozen pans are inserted in multiple stages, there is a large difference in the load on the top and bottom, so a highly rigid frozen pan is used to prevent the object to be cooled from deforming? Because it is used, it becomes a thermal resistance and the cooling performance of the lower surface is inferior.

[Summary of the invention]

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and includes a refrigerating conveyor that automatically carries in and out the objects to be cooled, and a flexible W sluice on the upper surface of the conveyor. A low-temperature vessel connected to the introduction inlet and flowing with low-temperature cooling fluid? The design is such that the material to be cooled is sandwiched between the refrigerating conveyor and the sub-container I, and the conveyor is used to take in and take out the refrigerated material, saving labor, and since the load applied to the first low-temperature container is constant, The object of the present invention is to provide a device r that improves cooling performance by cooling a direct wave cooled object without using frozen bread.

[One embodiment of the invention]

Is this an example of this invention? The diagram will be explained.

In FIG. 2, 0η is the lower surface of the large low-flow valley device 3) through which the low-vortex fluid (9) flows in a hermetic manner, and μs is the upper surface. value υ.

My sister is touching the low temperature fluid (9) inlet pipe, and her bag is the same outlet pipe. θ1) is a flexible tube installed between the inlet tube and the outlet tube. The decoy is a rotary conveyor belt with 14 driven pulleys! Rotate by J-Jll.

Below the belt σ1 is an enclosure +101 for flowing low-vortex fluid.

(102) is provided in the shape of a bento box without a lid, and the structure is such that the low temperature fluid flowing in from the beginning of the TYC conduit overflows from the surrounding enclosure (102) provided in the lower enclosure (101). . (110) is an outlet pipe i installed at the bottom of the oak to receive the overflowing low horse fluid chamber.
It is connected to the outlet main pipe by B4.

FIG. 8 is a cross-section of FIG. 2 at arrows A, B, and C. In the figure, (■) supports the large recessed temperature container (3), and in addition to assisting in moving the large refrigerated container (3) up and down using the vertical movement device (8+), the container (3) is
) movement t! Regulation of ligation. (64 is a pressure equalizing pipe.

Next, the operation will be explained.

The objects to be cooled (1) are conveyed by the belt 4 of the freezing conveyor and arranged on the upper surface of the enclosure (101). This is performed by stopping the drive pulley and one of the driven pulleys, but the control is a well-known technique and will therefore be omitted.

When the above arrangement is completed, the large low temperature container (3) is lowered by the vertical movement device (81) and set so that the lower surface @η of the container (3) is in sufficient contact with the object to be cooled (1). At this time, does the flexible tube (movement) and sideways prevention ■ move? Make it smooth.

Next, the low-temperature cooling fluid (9) flowing in from the inlet pipe Ill cools the object to be cooled (11' from the upper surface through the lower surface of the container), and continues to flow into the outlet pipe all [k through V main pipe I4]. Meanwhile, the low vortex cooling fluid all flows into the conduit (102) and overflows from the enclosure (102).
The object to be cooled (1) is cooled from the lower surface via ll'. The overflowing low-temperature cooling fluid all flows into the cypress (110) and the outlet pipe 10j9 into the main pipe (9) and joins with the n fluid (9).

finish.

In the above embodiment, the main pipe I [14vl] is located at the bottom of the device, but all the pipes such as the beak are gathered at 'a (110), and the main cooling liquid (9) and 6]11' are collected from the bottom of the tank. It doesn't matter if you go back to . Also, although the support ■ is divided into two parts, it also looks like a single body. Furthermore, the number of inlet/outlet pipes for the high cooling liquid may be divided into any number of pipes. Also, does the lower surface Oυ of the large adult horse container (3) have a flexible shape so that it can be attached to the object to be cooled (1)? Although it is shown here, any rigid or thermally conductive material can be used. It is also unthinkable to provide a stopper (120) or the like to prevent the lower surface 0υ from being set lower than necessary.

〔Effect of the invention〕

As described above, the present invention enables cooling by a single large paper sub-container connected to the introduction inlet via a flexible pipe system and a freezing conveyor, instead of using a large number of conventional heating containers. thing? The pond is sandwiched between the ponds and cooled from the top and bottom, which saves labor when carrying in and out of objects to be cooled.

Since the load to be pressed can be limited, cooling can be performed without using a rigid freezing pan, which has the effect of improving the cooling effect from above and below.
