Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a food cooling chamber which cools a hot cooked food to about room temperature, for example, in order to prevent deterioration of the food and deterioration of texture before packaging. And a food cooling device provided with a cooler and a blower for circulating and supplying cooling air to the food cooling chamber.

[Conventional technology]

Conventionally, as shown in FIG. 4, a cooler (23) and a blower (24) are provided inside a box (22) for accommodating a food (21), and air cooled by the cooler (23) is blown by a blower (24).
Thus, the air in the box (22) is sucked and supplied to the cooler (23), and the cooling air is circulated and supplied to the food cooling chamber.

[Problems to be solved by the invention]

However, since the air in the box (22) was simply agitated by using the blower (24) to blow the cooling air to the food (21), the temperature at each position in the box (22) was reduced. It became uneven and some food (21) was likely to corrode. In addition, there is room for improvement from a sanitary point of view, such as inadequate circulation of cooling air in a specific portion in the box (22), making it difficult to remove various bacteria and spoilage bacteria in the box (22).

On the other hand, a large amount of steam is generated from the food (21), so that the amount of dew condensation in the cooler (23) becomes enormous and the dehumidifying efficiency of the cooler (23) is reduced, and troubles due to dew condensation near the cooler (23) are caused. Easily occurred, and there was room for improvement in terms of performance improvement.

An object of the present invention is to provide a food cooling device that can cool food in a hygienic manner, improve the dehumidification efficiency of the cooler, and sufficiently prevent trouble due to dew condensation near the cooler.

[Means for solving the problem]

The characteristic configuration of the present invention is that a high-performance filter is provided in a cool air supply path from the cooler to the food cooling chamber, and a cool air supply port formed substantially over one side wall of the food cooling chamber, and substantially the other side wall of the food cooling chamber. A first perforated plate and a second perforated plate, both of which form a vertical plane, are provided separately from each other in an air discharge port formed over the entire body in a state where the first perforated plate and the second perforated plate are opposed to each other. An air reduction passage, in which a dehumidifying filter is arranged adjacent to the lower side of the second perforated plate along the second perforated plate, and the operation and effect are as follows. .

[Action]

In the cooling device of the present invention, the second perforated plate of the first perforated plate, which forms a vertical plane, with respect to the cold air supply port and the air discharge port respectively formed on substantially both side walls of the food cooling chamber. Each body is provided in a state where the body is opposed to each other. Thereby, the cooling air flowing into the food cooling chamber after passing through the first perforated plate-like body flows in while being appropriately dispersed in the plurality of holes formed in the first perforated plate-shaped body. The cooling air in the cooling chamber forms a laminar flow with no disturbance in the flow.

On the other hand, the cooling air discharged from the food cooling chamber through the second perforated plate is dispersed and discharged by the plurality of holes formed in the second perforated plate, so that the cooling air inside the food cooling chamber is cooled. The laminar flow is maintained up to the vicinity of the second perforated plate without adversely affecting the state of the air. in this way,
With this configuration, a laminar flow can be formed in substantially the entire area of the cooling chamber, so that all foods to be cooled can be cooled under substantially the same conditions. This ensures that all foods are cooled, prevents inconvenience such as corrosion of some foods, and effectively discharges germs and the like in the cooling room.

Further, when the flow of the cooling air is set in the horizontal direction, the flow of the cooling air is not disturbed, so that the chance of rolling up dust and the like on the floor is reduced, and a more sanitary cooling device can be configured. it can.

Furthermore, the cooling device of the present invention is provided with a high-performance filter, and cools the food while purifying the cooling air with the high-performance filter. Therefore, it is possible to reliably prevent various bacteria and spoilage bacteria from attaching to the food.

On the other hand, in the apparatus of the present invention, air containing steam or saturated steam discharged from the food cooling chamber is removed by a dehumidifying filter provided along the lower side of the second porous plate-shaped body. As described above, since the cooling air is uniformly discharged from the respective holes of the second perforated plate, the cooling air having the same water content also flows through the individual portions of the dehumidifying filter. As a result, the dehumidification load of the dehumidification filter is equalized. As a result, the dehumidification function in each region is reliably exhibited, and the highest dehumidification effect can be obtained as a whole.

And, since the water in the cooling air can be more effectively removed before the cooling air reaches the cooler, the amount of dew condensation in the cooler installed on the lower side thereof is sufficiently reduced, and the dehumidifying efficiency of the cooler is improved. At the same time, it is possible to prevent a cooler trouble due to dew condensation.

〔The invention's effect〕

As described above, the food cooling device of the present invention can provide a food cooling device that is excellent in food hygiene and excellent in dehumidification performance and maintenance.
