The vacuum pre cooling machine for shiitake mushrooms is a device used for preserving shiitake mushrooms. By using vacuum pre cooling, it can effectively reduce the temperature of shiitake mushrooms and extend their shelf life. The specific introduction is as follows:
1. By using vacuum pre cooling technology, the temperature of shiitake mushrooms can be lowered to a suitable storage temperature in a short period of time, effectively maintaining the quality and taste of shiitake mushrooms.
2. Made of high-quality stainless steel material, it has good corrosion resistance and wear resistance, and a long service life.
3. The equipment adopts an automatic control system, which is easy to operate and can achieve automated production.
4. During the pre cooling process, the pre cooling effect of shiitake mushrooms can be controlled by adjusting the vacuum degree and time to meet the needs of different shiitake mushrooms.
5. The equipment has good sealing performance, which can effectively prevent pollutants and bacteria from entering the air, ensuring the hygiene quality of shiitake mushrooms.
6. It can be used in conjunction with other devices to form a complete production line, improving production efficiency and automation level.
Working principle and pre cooling method
The working principle of the mushroom vacuum pre cooling machine is to use a vacuum pump to extract the air from the sealed pre cooling chamber, reducing the indoor pressure. At the same time, through the circulation of the cooling medium, the heat is carried away, thereby reducing the temperature of the material. There are two main methods for pre cooling:
1. Air pre cooling: Place shiitake mushrooms in a completely enclosed space and use a vacuum pump to extract air, reducing the indoor air pressure and thus lowering the temperature of the mushrooms.
2. Cooling medium pre cooling: Place the mushrooms in a container with a cooling medium, and through the circulation of the cooling medium, remove the heat, thereby reducing the temperature of the mushrooms. Common cooling media include water, ice cubes, salt water, etc.
Application Areas
Food industry: Vacuum pre cooling preservation of edible mushrooms such as shiitake mushrooms, fungus, Tremella fuciformis, and Ganoderma lucidum.
Pharmaceutical industry: Vacuum pre cooling preservation of Chinese herbs, medicinal materials, health products, etc.
Chemical industry: Vacuum pre cooling preservation of chemical reagents, chemical raw materials, etc.
Biological products industry: Vacuum pre cooling preservation of blood products, vaccines, biological products, etc.
Agriculture: Vacuum pre cooling preservation of mushroom strains, culture media, etc.
Research field: Vacuum pre cooling preservation for laboratory research, sample processing, etc.
Precautions and maintenance methods
1. Before use, check whether all components of the machine are intact and whether the oil level of the vacuum pump is normal. If there are any abnormalities, they should be dealt with in a timely manner.
2. Before starting, check whether the vacuum system is well sealed. If there is any leakage, replace the sealing ring in a timely manner.
3. During the pre cooling process, attention should be paid to observing the vacuum degree and time to ensure the pre cooling effect.
4. Regular inspection and replacement of filters should be carried out during the use of the machine to ensure the cleanliness of the vacuum system.
5. After use, the machine should be cleaned and maintained in a timely manner to extend its service life.
6. The machine should be protected from moisture and corrosion, and should be stored in a dry and ventilated place.
