Description

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

[Prior art]

A conventional device of this type is shown in FIG. In the figure (11 is the object to be cooled such as surimi, (2) is (1)
The frozen bread to be stored (3) is a low-temperature container that holds the frozen bread above and below. (5) is an inlet pipe for introducing the low temperature cooling fluid (9), and (6) is also an outlet pipe. (4) is above +51
A flexible tube connecting (6) and (3) is used to connect concave cooling fluid (9).
) are connected to prevent leakage. Is (8) the effect of cooling the object 12) from above and below with the vortex resistance fluid (9)? This is a weighting device that presses the frozen bread (2) against the solid floor (7) at the bottom of the tray to increase the height.

Next, the operation will be explained.

Cooled object (1)? The packed frozen bread +21 is manually inserted between the bread 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 (7).
Includes 1k.

Thereafter, the low-temperature cooling fluid (9) sent by a liquid feeder (not shown) sequentially flows through the introduction inlet pipe (5), the low-temperature container (3), and the outlet pipe (6) to cool the object (1). is cooled down.

When the cooling is completed, the load vI is loosened in the opposite manner as described above, and the frozen bread is again carried out manually.

After that, what about decoration devices that are not shown? The object to be cooled (1
) The whole frozen bread f21 is depanned and sent to the next process.

Since the conventional apparatus is constructed as described above, it has the following drawbacks: (1) A large amount of human effort is required to put in and take out the frozen bread (2).

(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. It has a cooling performance of

[Summary of the invention]

This invention was made to eliminate the drawbacks of the conventional ones as mentioned above. A refrigerated conveyor that automatically enters and unloads and a low-temperature cooling fluid flows on the top surface of the conveyor n2
+By installing a low temperature container, the object to be cooled is sandwiched between the freezing conveyor and the low-mounted container to cool it, and the conveyor takes in and out the object fL, saving labor and keeping the load applied to each stage of the low temperature container constant. Therefore, the object of the present invention is to provide a device that directly acoustically cools the object to be cooled and improves cooling performance without using a refrigeration tank.

[Embodiments of the invention]

A one-shot embodiment kl/ of the present invention will be described below.

In Figure 2, the 2% cryogenic container (3) is placed horizontally rather than in multiple stages.
They are arranged in one column. The inlet inlet pipe (5), the outlet pipe (6) and the flexible tube (4) are therefore all arranged horizontally. In addition, as many weighting devices (8) are installed as there are low-mounted containers. Fourth is the pulley υ driven by the base of the rotary conveyor.
2 Depending on the direction of the driven pulley (F!J rotation).

Below the belt 4, there is an enclosure (i o
1).

(102) is provided in the shape of a lunch box without a lid, and the low septic fluid button (low septic fluid button) that flows in from the conduit (6) provided in the lower enclosure (101) is connected to the surrounding enclosure (1 (12)). It has an overflow structure. (110) is a cypress that receives the overflowing low temperature fluid and is connected to the outlet main pipe by an outlet pipe provided at the bottom of the tank.

(See Figure 8 for the pressure equalization pipe. Arrows A and B are in Figure 2.)

This is a cross section taken at point C. In the figure, 6 is a connecting pipe that connects the outlet main pipe and the outlet pipe (6J?).

(120) is a stopper. (9) is a resistive fluid.

The following operation will be explained.

The object to be cooled (1) is conveyed by a belt 4 of a freezing conveyor and laid flat on the upper surface of the enclosure (101). This is done by stopping the operation of drive pulley 4 and driven booleans v and a11.

However, since it is a technique that is common knowledge, it will be omitted.

When the above arrangement is completed, the cryocontainer +31'k 7X1
It is lowered by a heavy equipment (8) and set so that the lower surface 0p of the container (3) is in sufficient contact with the object to be cooled (1).At this time, the flexible tube (4) moves smoothly.

Next, the low-temperature cooling liquid (9) flowing from the introduction pipe (5) passes through the lower surface of the container (1) to the object to be cooled (1). Cooling from the top, outlet pipe (6), connecting pipe 111? Flowing into the l-way main pipe? continue. On the other hand, the low-temperature cooling fluid @1) flows in from the conduit (9), overflows from the enclosure (102), and cools the object to be cooled (1) from the lower surface thereof via the pipe ff1. Overflow L7tllt tiger cooling fluid set) is in
(11 (1) and exit pipe 1a12 flow to main pipe @ Xun
A pressure equalizing pipe with the atmosphere is provided to make the first flow that merges with the fluid (9) smooth.When cooling is completed, the fluid (9) and II)k are stopped and the container (3) is pulled upward. Next, the four belts are operated, and the cooling material is transported to the next process for a series of cooling processes. finish.

In the above embodiment, the main pipe 141' is the lowest part of the device, but all the pipes such as fllllBl are connected to the tank (11a).
The cryogenic cooling liquid (9) and all' are collected from the bottom of the cypress.
It doesn't matter if you go back to .

In addition, a stopper (120 mm) is provided to prevent the lower OTJ of the low temperature container (3) from being set lower than necessary.
) etc. is also considered.

〔Effect of the invention〕

As described above, according to the present invention, instead of using conventional wet containers in multiple stages, they are arranged in one horizontal row and one stage, and the object to be cooled is sandwiched between the cryogenic container and the freezing conveyor and cooled from above and below. In addition to saving labor when carrying in and out of refrigerated items, the frozen pan is rigid because it can limit the pressing load r. Since it can be cooled even when not in use, it has the effect of improving the cooling effect from above and below.
