Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooling chamber that rapidly lowers the temperature to a predetermined temperature after heat sterilization.

Conventionally, heat sterilization treatment has been performed at a high temperature of 65° C. or higher, and room temperature treatment has been carried out by leaving the material in the natural atmosphere or placing it in a cold atmosphere to bring the material to a more normal temperature.

The former requires a long time and has hygiene problems;
The latter had the disadvantage of requiring large processing energy.

The present invention compensates for these drawbacks by lowering the pressure inside the hot/cold chamber and making maximum use of the heat of vaporization of water by spraying cold water, thereby saving cooling energy and performing rapid cooling in a sanitary manner.

In detail, this invention is a sealed refrigerator made of a heat insulating material: a ceiling (1), a side plate (2), a board (3), a door (6), and a packing (8). Room (41
However, a machine room (19) is provided by the partition plate (15), and the machine room contains a cooler (7), a water cooler (17), a fan (5), a cooling coil (14), a duct (12), and an inlet (10). , a hot/cold room (4) consisting of a discharge port (11) and a condenser (16).
In the rapid cooling warehouse where the sprayer (18) is attached, high temperature sterilized products are carried into the cold room (4) at the current temperature, and when the door (8) is closed, the heater (13) is activated and the fan is turned on. By (5), hot air is sent into the hot/cold room (4) to raise the temperature inside the hot/cold room (4) to sterilize bacteria from the outside, and then the operation of the heater (13) is stopped, and then the fan (5) is activated to lower the pressure inside the hot/cold room (4), and then the water supply machine (17) is activated to spray the cold water in the cold water machine (17) with the sprayer (18). ), the cold water pumped by the water chiller (17) is sprayed from the sprayer (18) and evaporation is promoted by the low pressure and high temperature in the hot/cold room (4), and the heat inside the hot/cold room (4) is accelerated. is absorbed into the hot and cold room (4)
The internal temperature will be lowered.

Next, when the cooler (7) is activated, the air in the hot/cold room (4) with a high temperature is sucked in and circulated by the fan (5) through the suction port (10) and flows into the activated cooling coil (14). The absorbed water droplets fall into the air tray (16), and the circulating air is dried and discharged into the hot/cold room (4).
4) Heat is absorbed by the heat of evaporation from the cold water spray and the dry cold air from the discharge port (11), and the temperature is rapidly lowered. Temperature chamber (4) When the 4 temperature reaches the specified temperature, the water cooler (1
By stopping the operation of 7), stopping spraying, and continuing to operate the cooling machine (7) and fan (5) until the required low temperature is reached, drying in the hot/cold room (4) is promoted and the temperature is lowered. . The same hot and cold room (4) is also used when unsterilized and processed products are brought in.
Close the carry-in door (8), turn on the heater (13), circulate hot air with the fan (5), raise the temperature inside the hot/cold room (4), and maintain the temperature at 72-75°C for 15 minutes, equivalent or higher. The high temperature sterilization process is carried out at a temperature and time that produce the effect, increasing the rotation of the fan (5) and lowering the pressure in the hot/cold room (4), thereby operating the water cooler (17) and spraying the sprayer (
At step 18), when the mixture is sprayed into the hot/cold room (4) with high temperature and low pressure, the heat of vaporization is absorbed and the temperature inside the hot/cold room (4) is rapidly reduced.Next, when the cooler 07 is activated, Hot/cold room 04
When the temperature inside the heating/cooling room (4) reaches the specified temperature, the operation of the water cooler (17) is stopped, spraying is stopped, and the cooling machine (power, Fan (5
), the drying inside the hot/cold room (4) is promoted and the temperature is lowered, thereby achieving the purpose.

b) By raising the temperature itself, heat sterilization is performed and the temperature is lowered.

口）By lowering the pressure inside the room and spraying cold water, we can maximize the use of pressure heat and save on cooling energy.

c) No contamination of bacteria from the outside during treatment due to the failure of the airtight refrigerator.

It has the following effects, and the cropping can be carried out automatically.

Such a rapid cooling chamber maintains the sanitary safety of foodstuffs, etc., and its contribution to the food industry is immeasurable in that it saves time and energy.
