1、 Cleanroom cleanliness level
The purification level of edible mushroom factories needs to reach the 10000 level standard, and the outlet of high-efficiency filters needs to reach the 100 level standard.
This purification standard is a regular purification room, which is a clean room in a mushroom factory. Generally, there is a large amount of logistics and human flow, and there must be daily flow of people and logistics. According to the experience of Mushroom Xingtianxia, a Class 10000 clean room can reach the Class 10000 standard in a static state. When it is produced, such as cooking, cooling, and inoculation, the number of dust particles increases rapidly, and the purification level cannot be guaranteed.
Therefore, the purification level of the purification room in the edible mushroom factory has been raised to 1000 levels, and it is necessary to increase the circulating air volume and number of cycles to ensure the dynamic purification level during production.
2、 The clean room is equipped with ultraviolet Germicidal lamp and ozone generator
Edible mushroom purification rooms generally do not use drugs for disinfection, so when designing purification rooms, ultraviolet lamps or ozone generators should be installed to disinfect the space.

3、 Wear resistant treatment of the clean room floor
The ground of the pre cooling room, cooling room, and inoculation room must consider whether it can withstand the rolling of the turnover vehicle wheels. Once the ground is damaged, it is difficult to repair. Ordinary epoxy self-leveling cannot withstand the frequent and high-strength rolling. It is recommended to make a new type of wear-resistant ground, which is more expensive but sturdy and durable.
4、 Design 10-15% fresh air volume
Maintaining a fresh air volume of 10-15% in the circulating air of the mushroom clean room can ensure that the air in the clean room is fresh, the ambient air is in a dynamic flow state, and the environmental indicators are more stable.
5、 The primary and intermediate efficiency filters should be easy to replace
Primary and intermediate efficiency filters are generally made of washable materials, and should be designed to facilitate disassembly and installation during cleaning.
6、 Increase the air volume of the air shower room
Generally, purification companies design air shower rooms according to national standards with a relatively small air volume, resulting in a large amount of dust brought in by the movement of personnel in the inoculation room. Therefore, it is recommended to increase the air volume in the air shower room.
7、 The pre cooling room, cooling room, and inoculation room are interconnected, and the specific work process should be clearly explained to the purification company to avoid mutual influence of pressure differences among the three purification rooms.
