Culture material disinfecting method for factory culture of edible fungus

Abstract

The invention belongs to the producing technology for edible fungi, which relates to a cultivating material sterilizing method for factory cultivating the edible fungi. The detain procedure is that: placing the cultivating material inside a sterilizing boiler, heating the boiler to 101DEG C. to 105 DEG C. by switching in high steam, maintaining the heat for 45min to 48min after heating for110min to 112min, then reheating to 121 DEG C. to 126 DEG C. and maintaining the heat for 90min to 92min after heating 45min to 48min and cooling naturally in the end. The invention can prevent the escaping of the fungi in normal technics effectively with thorough sterilization and also the exceeding boiling in the normal technics, which, therefore, little damages the nutrient content in the cultivating material and features easy controlled technics procedure, thus it is suitable for factory production.

Description

technical field [0001] The invention belongs to the production technology of edible fungi, and relates to a method for sterilizing culture material for industrial cultivation of edible fungi. Background technique [0002] In the industrial production process of edible fungi, cottonseed hulls, waste cotton, sawdust, bean stalks, corncobs, wheat bran, etc. are generally mixed with water in proportion and then packed into bags to make compost. The culture material needs to be sterilized to prevent harmful bacteria contamination during the cultivation process. The existing compost sterilization method is generally to place the compost in a sterilizing pot and feed it with high-pressure or normal-pressure steam to cook it at a high temperature for a period of time and then cool it down. In the existing sterilization method, if the cooking temperature is too high, the nutritional content of the compost will be destroyed, and if the cooking temperature is too low, the sterilizatio...

AI Technical Summary

Problems solved by technology

In the existing sterilization method, if the cooking temperature is too high, the nutrient content of the compost will be destroyed, and if the cooking temperature is too low, the sterilization effect will be reduced, so it cannot meet the requirements of use.
