Embodiment Construction

[0016] Mode 1: In the present embodiment, mushroom wheat grain compost is packed into 1100ml×78mmPP plastic bottle, and the weight of each bottle is 680g (wet material). three times).

[0017] Operation method:

[0018] ①Put the strain bottle (bag) filled with culture material into the atmospheric pressure sterilization stove, and place it reasonably, especially the stack of the strain bag should not be too tight, and an appropriate gap should be left to allow the steam in the stove to sterilize. Flow, the culture medium is evenly heated;

[0019] ②First sterilization: At the initial stage of sterilization, use a high fire to make the temperature of the lower half of the warehouse reach 100°C in a short period of time to control the increase in the number of microorganisms in the bottle (bag), and then change to a high fire. For simmering, continue to steam for 6 hours, at this time, the vegetative body of the bacteria has been killed, but the spores are still alive;

Abstract

The invention relates to an ordinary pressure intermittent sterilization method which can be used for achieving the complete sterilization effect in the production of wheat cultures of edible fungus. Compared with the high-pressure sterilization technology, the ordinary pressure intermittent sterilization method has the advantages that the inherent nature of the cultures is retained to enable vitamin to be affected by pyrolysis as less as possible and to reduce the nutrition effect decline of protein; the expensive high pressure equipment investment is omitted to obtain great application values, especially for small rural township enterprises.

Description

technical field [0001] The invention relates to an atmospheric pressure intermittent sterilization method for producing edible fungus barley strains, and belongs to the technical field of edible fungus sterilization. Background technique [0002] The wheat grain strain has the advantages of strong mycelium, whiteness, and rapid germination after inoculation, so it is very popular among mushroom growers. At present, wheat grain strains have been widely used in the production of strains of various edible fungi. [0003] Due to the large size of the wheat grain itself, the rich crude protein content, the low water content (45%), and the high porosity of the grain in the bottle (bag), the air volume in the bottle (bag) increases, and the air is bad. The heat transfer medium affects the conduction of steam. Therefore, the sterilization time of wheat pellets is relatively longer than that of sawdust compost. The principle of sterilization time is to kill all microorganisms in th...
