Edible mushroom vacuum pre cooler

The pre cooling steps of the edible mushroom vacuum pre cooler are as follows:

1. Put fresh edible mushrooms into the pre cooling machine to ensure that the temperature and humidity of the mushrooms meet the requirements.

2. Turn on the vacuum pre cooler and adjust the vacuum degree to an appropriate value, usually below 5Pa.

3. The pre cooling time depends on factors such as the type, size, and freshness of the edible mushrooms, and is generally 30 minutes to 2 hours.

4. After pre cooling, remove the edible mushrooms and place them in the cold storage for refrigeration.

Notes:

1. When using a vacuum pre cooler, attention should be paid to the freshness and temperature of the edible mushrooms to avoid excessive pre cooling.

2. During the pre cooling process, the vacuum degree and pre cooling time should be checked regularly to ensure the pre cooling effect.

3. When placing edible mushrooms in the pre cooling machine, attention should be paid not to overcrowding, so as not to affect the pre cooling effect.

4. The pre cooling machine should be regularly maintained and serviced to ensure its normal operation.

Maintenance method:

1. Regularly clean the interior of the pre cooling machine to ensure its cleanliness and hygiene.

2. Regularly check the vacuum degree and pre cooling time, and promptly repair and replace faulty components.

3. During use, attention should be paid to preventing edible fungi from contaminating the machine and affecting the pre cooling effect.

4. The pre cooling machine should be stored in a dry, ventilated, and non corrosive gas environment to avoid affecting its service life.

Functional principle:

The functional principle of the edible mushroom vacuum pre cooler is to reduce the temperature of the edible mushroom under vacuum state, thereby extending its shelf life. In a vacuum state, oxygen and moisture in the air are extracted, leaving edible fungi in an oxygen deficient and low humidity environment, thereby slowing down their metabolism and decay rate, and extending their shelf life. At the same time, the pre cooling machine can also reduce the temperature of edible mushrooms, reduce their cooling time in the cold storage, and improve the utilization rate of the cold storage.
