How is atmospheric-pressure sterilization carried out in wood ear mushroom cultivation?
How do you sterilize wood ear mushrooms at atmospheric pressure? Please explain the method. For the atmospheric-pressure sterilization method for wood ear mushrooms, you can refer to the following: 1. When loading the pot, leave a certain gap between baskets to prevent poor steam circulation, which would affect the sterilization effect. 2. After a large amount of steam is produced, be sure to open the vent to release cold air. When the temperature at the bottom inside the pot reaches 100°C, start timing.
How do you sterilize wood ear mushrooms at atmospheric pressure? Please explain the method.
For the atmospheric-pressure sterilization method for wood ear mushrooms, you can refer to the following:
1. When loading the pot, leave a certain gap between baskets to prevent poor steam circulation, which would affect the sterilization effect.
2. After a large amount of steam is produced, be sure to open the vent to release cold air. When the temperature at the bottom inside the pot reaches 100°C, start timing.
3. During sterilization, keep the temperature inside the pot no lower than 100°C, and the sterilization time no less than 8 hours, otherwise the sterilization effect cannot be achieved.
4. When water needs to be added in between, try to add hot water. If adding cold water, use a slow, steady trickle method, and the fire must be strong.
5. During sterilization, if the temperature inside the pot falls below 100°C, the timing must be restarted.
6. Maintaining the temperature inside the pot at 100°C should not exceed 13 hours; excessive sterilization time easily damages the nutrient content of the culture medium.
7. After stopping the fire, let the pot sit for 3~5 hours, then gradually open the pot door to prevent the air pressure difference between inside and outside the pot from crushing the mushroom bags.
