Field of the Invention The present invention relates to a vacuum cooling device for evaporating food by depressurizing and evaporating the moisture of the food, and utilizing the latent heat at that time. The present invention relates to a vacuum cooling device provided with a vacuum exhaust means connected to discharge a gas in a cooling box and an outside air introducing means for releasing a vacuum state in the cooling box. Here, the foods include various cooked foods obtained by seasoning and boiling tsukudani, seafood, beans, seaweeds, meats and the like.

詰めを行っている。2. Description of the Related Art As is well known, when a cooked food is packed in a container and shipped, in a high temperature state, water droplets due to steam adhere to the inner surface of the lid of the container and the like. Since there is a problem that water drops on food and impairs the flavor, the food is cooled and then closed or packed in containers.

収容し、該冷却庫を真空排気することにより食品中の水
分を蒸発させ、その蒸発の際の気化潜熱を食品から奪う
ことにより真空冷却する方法が注目されている。[0003] In a food factory such as a lunch box for mass production, it is required that the food be cooled in a short time. Therefore, conventionally, the cooked food is stored in a cooler, and the water in the food is evaporated by evacuating the cooler, and the latent heat of vaporization during the evaporation is removed from the food to perform vacuum cooling. The method has attracted attention.

にすることにより、実施されている。However, the slow cooling and slow pressure methods of the vacuum cooler are as follows.
Controlled by either time or pressure detection in the cooling cabinet, the external air is intermittently reduced or reduced in pressure while the outside air is being introduced into the cooling cabinet using the outside air introduction valve. In this way, the pressure reduction or the pressure recovery speed is reduced so as to be implemented.

起きる。[0005] In a vacuum cooling device, when the degree of vacuum is increased in the step of cooling the food, the moisture of the food starts to evaporate,
Rapidly increasing the degree of vacuum causes bumping. When this bumping phenomenon occurs, the food is blown out, the food may be fried, buns, fried eggs and the like may burst, and if the food is cooked rice or the like, a phenomenon of gradually "clogging" upon returning may occur.

悪影響があるという欠点があった。Therefore, conventionally, a plurality of solenoid valves are provided in the outside air introducing means for releasing the vacuum state in the cooling cabinet, and during the grinding process, several of these solenoid valves are opened by a timer to supply the outside air. However, in such a case, there is a drawback that the adjustment takes a long time, the adjustment changes depending on the amount and type of the food material, and the completion time changes, so that there is an adverse effect on the post-process.

Alternatively, if the throughput of the cooling material changes, the speed of evacuation, the degree of vacuum, and the cooling temperature change. In addition, since the temperature drop changes depending on the physical properties of the cooling material, the food material is damaged, and if it is boiled, the texture becomes worse and the liquid material is scattered.

By providing a controller that continuously detects the pressure sensor according to the initial temperature, the final temperature, and the like, and continuously operates the outside air introduction unit, the above-described disadvantages are eliminated.

できる。That is, by controlling the pressure in the cooling chamber by the control means so as to make the curve of the degree of vacuum parallel to the curve in which the temperature in the cooling chamber decreases, it is possible to change the vacuum state from the initial state to the final state. The boiling state is the same at each point, and sudden boiling of the food does not occur. This is because bumping occurs when the temperature of the food and the degree of vacuum are far apart. Therefore, stable cooling can be performed irrespective of the water temperature, the processing amount, and the like of the food. By changing the degree of parallelism, the best cooling for the food can be achieved.
