Description

[Detailed description of the invention] This invention relates to the shelves of a thawing cabinet that stores items to be thawed. This relates to an air circulation type defrosting machine that eliminates differences in temperature distribution within the refrigerator, enables uniform thawing throughout the refrigerator, and allows the shelf height to be freely changed to effectively utilize space inside the refrigerator. It is.

In general, most imported products such as meat are frozen at ultra-low temperatures to maintain freshness, and are thawed before reaching consumers.

However, the biggest problem with conventional thawing operations is maintaining the freshness and taste of meat, and drips of meat juice etc. may occur from thawed processed meat, reducing the product value, or frozen meat stored in the thawing cabinet may drip. There is a disadvantage that the thawing temperature and thawing speed of the thawing air inlet and outlet of the thawing air are inconsistent, resulting in uneven thawing. There was also the drawback that only a small amount could be stored in the refrigerator.

This idea was made in order to improve the shortcomings of the conventional example mentioned above, and the shelf board for storing thawed products is shaped in a zigzag shape and has a multi-tiered structure whose height can be freely changed. In addition to constructing a thawing shelf, the purpose was to widen the contact surface between thawed products and circulating air to shorten thawing time, and to facilitate drainage of drips and cleaning of shelf boards after thawing. This provides a thawing chamber for an air circulation type thawing machine.

Hereinafter, embodiments of this invention will be described in detail with reference to the accompanying drawings.

Figures 1 to 3 are a front sectional view, a cross sectional view, and a side sectional view of the thawing cabinet 1 according to this invention, and 2 is a front opening/closing door, and 3 is a shelf board for storing items A to be thawed. It is formed in a zigzag shape with a constant interval maintained between the left and right side walls and the opposing side walls alternately. A protruding support rib 3a is provided in the longitudinal direction of the upper surface to facilitate the flow of circulating air.

Also, on the left and right sides of the zigzag-shaped shelf board above,
A rectifying plate 4 in the form of a porous or perforated plate is installed, and is configured to uniformly rectify the circulating air and guide it to the flow path of the next stage.

At the starting end of the uppermost shelf board 3 in the thawing chamber 1, there is an inlet 5a1 of an introduction duct 5 that introduces circulating air such as high humidity air made by a perforated gas-liquid contact tower (not shown) and the lowermost stage. At the end of the shelf board 3, there is an exhaust duct 6 for discharging the air that has circulated inside the refrigerator.
The entire shelf board 3 forms one continuous duct-like air circulation flow path from the upper stage to the lower stage.

Further, the opening/closing door 2 is used for taking in and out the thawed product A, and a sealing material 7 is fixed to the back side of the opening/closing door 2 at a position corresponding to all the shelf boards 3 so as to have a sealing function. Each shelf board 3 forms an independent air flow path.

Furthermore, a drip stop 8 is installed at the lower part of the lowest shelf board 3 of the thawing warehouse 1, and the water is discharged to the outside from a discharge pipe 9 via a water gradient 8a.

In addition, a turbulent flow plate 10 is attached or detachably hung downward from the shelf plate 3 that corresponds to the ceiling of each of the above-mentioned shelf plates 3, so that the air flowing through the air flow path sufficiently hits the downstream side of the product A to be thawed. At the same time as ensuring a constant wind speed.

FIGS. 4 and 5 show an enlarged side sectional view and a front sectional view of the shelf board 3 according to this invention, and explain the flow of the circulation flow to the product A to be thawed.

Note that a protruding support rib 3a is provided on the upper surface of the shelf board 3 to lift the item A to be thawed so that air can also hit the lower side. In addition to the above, a shelf board having a wave shape in the longitudinal direction may be used as shown in FIG.

In addition, a water slope is provided on the shelf board 3 to ensure a flow path for drip flow, and drain holes and plugs 3b are provided between the side wall of the thawing chamber 1 and the rectifying plate 4 as necessary. Good.

On the other hand, a water gradient is provided to ensure a drip flow path for the shelf board 3, and the height of the shelf board 3 can be changed according to the shape and dimensions of the product A to be thawed. As shown in FIG.
1 is provided and engaged with a predetermined position of this recessed part 11 to form a shelf board 3.
The shelf board 3 is provided with a support 12 that supports the support 12.
Can be mounted at any height via.

In this case, the shelves 3 are tilted alternately between the opposing side walls of the thawing chamber 1 to form a water gradient in the lower lip flow path.

Further, FIG. 8 shows another embodiment showing an example of mounting the shelf board 3 according to this invention, in which the inner wall surface of the main body of the thawing chamber 1 is provided with protrusions 13 maintained at a predetermined interval. This is a case where the shelf board 3 is placed in the position.

As explained in detail above, the thawing chamber of the air circulation thawing machine according to this invention has a simple structure, and the height of the shelves can be freely changed according to the shape and dimensions of the items to be thawed.
Since the items to be thawed receive circulating air over the entire surface on the shelf board and are thawed uniformly, the thawing efficiency is further improved and the volume inside the refrigerator is not wasted.

Moreover, there is no problem that drips fall automatically and contaminate the items to be thawed, and the thawing time can be shortened.
