Dry heat type secondary fermentation method for planting agaricus blazei and dry heat type heating device

Abstract

The invention provides a dry heat type secondary fermentation method for planting agaricus blazei and a dry heat type heating device. The dry heat type heating device is characterized in that the dry heat smoke and fire generated by a built-in range directly heat the culture medium in a mushroom house to complete the secondary fermentation method. The method comprises the following steps that: the built mushroom houses face south; in each mushroom house, 2 to 3 heating ranges are built, each range is arranged on the south of the mushroom house and between bed frames of two mushroom beds closer to the middle, and the range is 20 to 50cm away from the ends of the two bed frames; the ranges are heated after the culture medium is put on the mushroom beds in the mushroom house, the hot smoke directly enters the mushroom house for heating, when the temperature rises to be between 56 and 58 DEG C, the temperature is kept for 48 to 52 hours, and when the temperature drops to be between 40 and 45 DEG C, the temperature is kept for 72 to 120 hours; and the dry heat type heating equipment or device is a built-in range with a cylindrical range body, the range opening faces south, and a smoke-dispersing top cover is arranged above the hot smoke-discharging opening of the range body. The dry heat type heating device has the advantages of simple operation, short heating time, energy and labor conservation, small nutrient loss, a small number of ranges, low environmental pollution and the like.

Description

(1) Technical field [0001] The invention relates to an edible fungus production technology, in particular to a new dry-heat secondary fermentation method and a dry-heat heating device for cultivating Agaricus blazei. (two), background technology [0002] At present, the traditional fermentation technology for cultivating Agaricus blazei requires pre-fermentation (also known as primary fermentation) and post-fermentation (also known as secondary fermentation). The specific fermentation methods include: stacking the compost for the first fermentation (that is, pre-fermentation), and the secondary fermentation method is to put the culture material into the mushroom house (also known as the mushroom shed) and then carry out the second fermentation after the culture material has been pre-fermented. ) before the mushroom shed is routinely disinfected and sterilized. When entering the bed, it is stacked on the second, third, fourth, fifth, and even sixth floor bed frames. After all...

AI Technical Summary

Problems solved by technology

[0003] The disadvantages of the above-mentioned secondary fermentation technology using steam heating are that the operation process is cumbersome and troublesome, workers need to frequently add water to the stove, the fire takes a long time, the heat energy utilization rate is low (a large part of the heat is taken away by the hot flue gas), and the consumption of coal or firewood The cost is high, the environment is seriously polluted, and the growth rate of actinomycetes is too fast, there are many kinds of bacteria, and the loss of nutrients is large
