Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a construction in which a pair of ventilation ports of a thawing machine are provided with multiple shelves for storing products to be thawed, and a can opening is connected to a box-shaped cart having openings on both sides. and a predetermined wind direction changing cart is connected to the opening in the end face of the box-shaped cart.
! t regarding the IF freezer.

Generally, in a thawing device, the purpose of creating a connected trolley air circulation path is to control the temperature and humidity by controlling the temperature and humidity.
If freezing (f), it is possible to distribute air as evenly as possible to the thawed items in the refrigerator.

In other words, the trolley connection method connects trolleys with cross-sectional areas suitable for the processing claws to form an air circulation path, which minimizes the air volume while maintaining a rectifying effect. Moreover, since the finish of the V-thawed product is constant -T7+ within the allowable length, it is important to reverse the direction of wind movement at appropriate time intervals.
Traditional thawing equipment to achieve the purpose of
Although the structure allows for large quantities of i'F4 R to be stored in a thawing warehouse with multiple groups of trolleys, there are problems with handling such as loading and unloading of thawed products and connection of trolleys due to large volume processing. Set (ji)

There are nine thawing machines constructed as described above.
Explain the sieving operation of li(l.

First, RJ and layered miscellaneous goods are stored on the shelves 11 to 1n of the trolley 1, and are connected so that the opening of the rectifying chamber 51C, which is 41 at the ventilation port of the thawing device, is in contact with the shelves 11 to 1n of the trolley 1, and then a large number of trolleys 1 are sequentially connected. be done. After the bogies f5i5R] are connected, the wind direction change bogies 13 are all connected and a duct is formed at -C,,yjD. Next, operate the control g41I panel 10 to operate the yJ freezing device to blow circulating air and cool the bogie I P-J.
This is to thaw the items to be thawed.

At this time, as shown in FIG. 3, the circulating air passes through the wind direction reversing chamber 4, is partitioned by partition plates 2 (VC, Ct), and is ventilated from the upper or lower side of the truck l, and then is ventilated by the reversing truck 13. Turn around and return to the wind direction reversal room 4 through the opposite side.
Thaw the Vf frozen product in the table 71jl uniformly.

Furthermore, if the above-mentioned ventilation in a certain direction is carried out for a certain period of time,
Since there will be a difference in the degree of defrosting between the upper and lower stages of the trolley 1, the timer and other switching devices 4 will be set to X, 9 Dan i!
- The ventilation pattern can be changed by switching the circulating air flow path, turning it upside down, etc.).

ψ FIGS. 4 to 7 μ are perspective views of essential parts showing an embodiment according to the present invention, and FIG. 4 is a partially cutaway perspective view of the truck 20. The above-mentioned bogie has 20 mounts, horizontal partition plate 20a and vertical partition plate 20b.
In room h, shelves or trays for storing items to be frozen are installed in multiple stages. Carriage 20 with the above-mentioned VC structure
In Fig. 5, j, j: sea urchin thawing device side is reversed 1tlL
21 is connected to a rectifying chamber 5 having a pair of ventilation holes, and a wind direction changing truck 22 is connected to the opposite side 11 to form a ventilation duct in the truck 2 (month η).

As shown in the above-mentioned inverted portions 21 fjF, TS G (Figs.) and (B), the outer periphery 10 is made of a 1tIr heat-resistant structure, and is divided into upper and lower parts by a horizontal partition wall 21a. The lower tier or upper tier m11 is divided by the horizontal partition wall 21a, and the partition wall 21b divides the lower tier or upper tier m11 into left and right parts, each of which communicates with one circulating air outlet or suction.The front and rear surfaces are open. are doing. Also, at this time, the engineering (
(Excluding the part partitioned left and right by the partition wall 21b, the lower part is left closed by the partition 21c, and the circulating air is turned left and right by the reversing chamber Pueno 1). There is.

Further, the wind direction conversion truck 22 is divided into left and right halves by a vertical partition wall z2 shown in FIG. 7, and the circulating air within the truck 20 is diverted upward and downward respectively on the left and right sides.

In addition, in FIG. 5, an fL guide groove 23 is formed in the passage of the cart 20, so that the carts 20 can be connected accurately and the carts 20 can be moved smoothly. .

Next, the cart 20 and the reversing section 2 configured as described above will be explained.
1. The defrosting operation by the wind direction changing cart 22 will be explained.

FIG. 8 shows a case where air outlets and suction ports are arranged on the left and right sides of the upper stage of the reversing section 21, and air is blown out from the left or right of the reversing section 21 to the left or right side of the cart 20. The air flows from the upper stage, is diverted down to the lower stage side by the wind direction changing cart 22, and returns to the reversing section 21 again. Since the lower side of the reversing section 21 is a reversing chamber, it can be reversed to the right or left side, and the airflow direction can be changed to the right or left side of the trolley 20 (11UJ: ff) to the wind direction changing trolley 22 to the upper stage side. It is something that will be returned to you.

After the above-mentioned ventilation has been carried out for a certain period of time, the damper is switched to a timer or other switching device, and the circulating air flow path is switched between the left and right sides, thereby changing the ventilation pattern.

In addition, in FIG. 8, if a structure in which the lower part of the horizontal partition wall 21a is divided into left and right sides by a vertical partition wall 21b is used in the reversing part 21, two ventilation patterns completely opposite to the above-mentioned ventilation pattern can be obtained. It is something.

In other words, the trolley 20 is separated by horizontal partition wall 20a1 vertical partition plate 20bV.
When the CL94 division L7 is used, four VCs can be selected for the ventilation pattern of the circulating air by appropriately setting the reversing section 21 and the wind direction changing trolley 22, so that the thawing inside the trolley 20 is averaged. It is done.

Note that as an application example of the present invention, the trolley 20 is
The same effect can be obtained not only by dividing the carriage 1 into 4 parts, but also by arranging the cart 1 divided into two parts vertically in two rows on the left and right as explained in FIGS. 1 and 2.

In addition, as shown in FIGS. 1 and 5, the guide 11 and the guide groove 23 are provided to facilitate the operation of connecting the carriages.
3'ffi is not used, and the frang device 32 between the carts 3o and the wind direction changing cart 31 arranged in two rows as shown in FIG.
It may also be possible to ensure reliable movement and connection.

This fluff equipment R3214 operating lever connects the P locking piece 32a to the handle 3 of the adjacent cart by means of a link mechanism. Also, the wind direction changing trolley 31
A spacer 31a corresponding to the longitudinal gap between the parallel carriages 30, 30 is erected at the center of the opening 31b.

Tao,〃id 11. The guide means such as the guide groove 23 and the flang device 32 are not limited to each embodiment, and can be used in arbitrary combination with various types of carts and connection modes.

As explained above in detail II (IlvC), the thawing device according to the present invention does not require a building for forming airtight walls such as a thawing warehouse, and construction is quick and easy.

Further, a ventilation path for circulating air can be easily formed by simply connecting the carts, and a ventilation pattern for each type can be set as appropriate.

Furthermore, depending on the number of carts, a ventilation pattern corresponding to the desired amount of thawing can be obtained, and uniform thawing can be carried out effectively in a short period of time.

In addition, it is easy to move, carry in, and take out one cart, and if you combine it with a guide or guide groove, or use a connecting fitting between the carts, you can eliminate the need for a guide or guide groove. There is a large degree of freedom in design.
