Embodiment 1

[0045] In each of the following examples, the compost was prepared according to the formula of compost 1 in the above-mentioned test example.

[0046] 1. Pack the culture material into bags: the culture material bag is a plastic bag with a diameter of 17cm x a length of 35cm. The thickness of the plastic bag is 0.004cm, and each bag is filled with 500 grams of culture material equivalent to dry material;

[0047] 2. Put the loaded culture material bags into the atmospheric pressure sterilization device: first put 6 culture material bags vertically and tightly into the iron basket, and place 10 baskets on each layer in the atmospheric pressure sterilization device, stacking them in total 8 layers, the temperature sensor is placed in the center between the third layer and the fourth layer from the bottom layer;

[0048]3. Heat sterilization: heat the atmospheric pressure sterilization device, and when the temperature sensor reaches 100°C, keep the temperature and continue to ste...

Embodiment 2

[0051] 1. Pack the culture material into bags: the culture material bag is a plastic bag with a diameter of 17cm x a length of 35cm. The thickness of the plastic bag is 0.004cm, and each bag is filled with a culture material equivalent to 525 grams of dry material;

[0052] 2. Put the loaded culture material bags into the atmospheric pressure sterilization device: first put 6 culture material bags vertically and tightly into the iron basket, and place 50 baskets on each layer in the atmospheric pressure sterilization device, stacking them in total 9 layers, the temperature sensor is placed in the center between the third layer and the fourth layer from the bottom layer;

[0053] 3. Heat sterilization: heat the atmospheric pressure sterilization device, and when the temperature sensor reaches 100°C, keep the temperature and continue to sterilize for 10 hours;

[0054] 4. Cooling and discharging: After stopping heating, discharge when the temperature of the material drops to 45°...

Embodiment 3

[0056] 1. Pack the culture material into bags: the culture material bag is a plastic bag with a diameter of 17cm x a length of 35cm. The thickness of the plastic bag is 0.004cm, and each bag is filled with 550 grams of culture material equivalent to dry material;

[0057] 2. Put the loaded culture material bags into the atmospheric pressure sterilization device: first put 6 culture material bags vertically and tightly into the iron basket, and place 100 baskets on each layer in the atmospheric pressure sterilization device, stacking them in total 10 layers, place the temperature sensor in the center between the third and fourth layers from the bottom;

[0058] 3. Heat sterilization: heat the atmospheric pressure sterilization device, and when the temperature sensor reaches 100°C, keep the temperature and continue to sterilize for 11 hours;

[0059] 4. Cooling and discharging: After stopping heating, discharge when the temperature of the material drops to 50°C.

Abstract

The invention relates to a method for sterilizing edible fungi under normal pressure, which belongs to an edible fungi producing method. The method comprises the following steps: cultivation material is packaged, and each package is filled with cultivation material which is equal to 500 to 550 grams of dry material; the filled cultivation material package is put into an Arnold sterilizer, and a temperature sensor is placed on a central position between a third layer and a fourth layer counted from the bottom layer; the Arnold sterilizer is made to improve temperature, and when the temperature sensor reaches 100 DEG C, the temperature is kept and sterilization is performed continuously for 9 to 11 hours; and after heating is stopped, the material is discharged after the temperature of the material falls to between 40 and 50 DEG C. The method has the advantages that the inoculated fungi is quick to sprout; hypha is quick to absorb the material; and the cultivation material package sterilized by the method is clean; when the hypha develops, the fungi is not burned and the material is not damaged; the mushrooms has high yield; and the biological conversion rate is high. The method solves the realistic problems in edible fungi industrialized production.

Description

technical field [0001] The invention belongs to a method for producing edible fungi. Background technique [0002] The industrialized production of edible fungi has made great progress in the production practice in various places. In the cultivation and production, after frequent pressure sterilization of the compost, there are still miscellaneous bacteria infections. The germination of inoculated bacteria is slow, the mycelium feeds slowly, and the culture bag is polluted; the mycelium often burns and spoils the material, resulting in low mushroom yield and low biological conversion rate. Contents of the invention [0003] The invention provides a normal pressure sterilization method for edible fungi to solve the problem of the current infection of miscellaneous bacteria, and the germination of inoculated bacteria is slow, the mycelium eats slowly, and the culture material bags are polluted; Mushroom yield is low, the problem of biological conversion rate is low. The te...
