Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a food cooling machine that can cool food to a temperature at which it can be consumed in a short period of time.

Raising the temperature of food to a finished state of around 100 ['C] and eating or drinking it immediately thereafter not only increases the risk of burns, but also lowers the efficiency of digestive enzymes in saliva, anticancer effects, and bactericidal effects. It is pathologically inappropriate because it reduces 'Also. As for the taste, in addition to not being able to fully enjoy it because it is above the optimum temperature for the sense of taste, there is also a psychogenic loss of taste caused by being careful when eating and drinking. However, in reality, if you don't have the time to wait for it to cool down naturally, or if you leave it to a temperature that is safe to eat, like ramen, the taste (overall evaluation) may actually deteriorate (hereinafter referred to as The overall taste evaluation, including flavor, aroma 2 elasticity, etc., is expressed as "taste").

In addition, freezing food not only has a negative impact on other foods, but also reduces thermal efficiency.

It is common practice to let the food cool naturally to some extent before placing it in the freezer, but this has the disadvantage that the cooling time is long.

The present invention was made in order to eliminate the above-mentioned drawbacks, and aims to provide a food cooling machine that enables a cooling process that shortens cooling time and causes little change in taste.

The details of the present invention will be described below with reference to the drawings and examples.

The first solenoid valve (9), the second solenoid valve (9), the power relay that controls 10 and 1, is operated by the pressure switch (11), and is for the buzzer that controls the buzzer. Relay (2+1 indicates a start relay which is operated by the start switch (171) and is used to control the ON state.

The operation of the embodiment of the present invention will be described in detail below based on nine drawings.

First, turn on the g power switch to cool down the food and drink. Buy 1 batch in the cooling room (5). While looking at the cooled (temperature is the set temperature) ship display 0a, turn the set temperature adjustment dial 11714

According to Fig. 4, the operating pressure of the pressure switch ttn is tas [, mHg], and above this pressure, the contact of the pressure switch (111) is set to high pressure Ha (11a).

If N, start relay c! D works. When you stop operating the start switch surface, the switch ON contact becomes OFF, but since the start relay Qll is self-holding, the current flows to the high voltage side (11a) contact of the pressure switch (Ill) and the power relay make it work.

Then, the second electromagnetic pulp constant 1 is closed, the inside of the cooling chamber (5) is cut off from the outside air, and the first electromagnetic pulp constant (9) is closed.
) is in the open state, and the cooling chamber (

The water temperature will gradually rise to 1 due to the latent heat of vaporization due to water vaporization. , at the same time, the pressure also decreases according to the relationship shown in Figure 4 σ).Now, when tooml of water is cooled by -hi MW + 'FI:, the latent heat of vaporization is 5

It becomes 40. That is, in order to cool from gs [°C] to 65 [°C], it is only necessary to evaporate about s, 61:ml]. About 5.6 [6th] evaporate. When the water temperature reaches 65 [℃], the pressure becomes 1a a Cmrn Hg') and the pressure switch αli 75K (Narita side (11b) contact is turned on. Then, the pressure switch αli 75K (Narita side (11b) contact is turned on. Then, the pressure switch αli 75K (Narita side (11b)) is turned off, and the pressure reducing pump is turned off.

Since the magnetic valve 01 is in the open state, the contact point of the pressure switch U is immediately reversed to the high pressure side (11a) by the force S, and unless the start switch αη is operated again, the power relay (1

The initial state shown in Fig. 3 is reached, and the edge is turned over and the cooling becomes +jJ.

As described above, this invention reduces the pressure inside the cooling chamber and uses the latent heat of vaporization from the food and drink to maintain the relationship between the temperature and the steam H1. It is possible to provide a food cooler that can cool food in a short time.
