Problems solved by technology

However, because the fungus bran contains a large amount of lignocellulose that has not been decomposed and utilized by edible fungi, the structure is tough, the texture is rough, and the palatability is poor. At the same time, because it contains nutrients such as mycelium and protein, it is easily spoiled and deteriorated, so it is not suitable for direct use as feed. The utilization of raw materials requires proper fermentation treatment

example 1

[0027] 1) Collection of mushroom chaff and analysis of nutritional components: collect fresh Pleurotus eryngii or Flammulina velutipes mushroom chaff from edible fungus production enterprises, measure moisture, dry matter, C, and N content, and transfer them to high-temperature fermentation tanks in time; The fermentation tank is 40m long, 1.5m wide and 1m deep.

[0028] 2) In the high-temperature fermentation tank, calculate the moisture, nitrogen source, and calcium hydrogen phosphate that need to be added according to the analysis data of the raw material moisture, dry matter, C, and N in the fermentation tank and the total mass of the bacteria chaff in the fermentation tank; The nitrogen source and tap water are fully mixed, the C / N is adjusted to 25, and the moisture is adjusted to 55%;

[0029] 3) Spray the fermented pyrolysis fermentation compound bacterial liquid on the bacterial chaff raw material in step 2); the spraying amount is 1% of the weight of the bacterial ch...

[0040] Example 2, same as Example 1, the difference is,

[0041] 1) The high-temperature fermentation tank is 60m long, 1.7m wide and 1.2m deep.

[0042] 2) Adjust C / N to 30, moisture to 60%;

[0043] 3) Spraying the fermented pyrolysis fermentation composite bacterial liquid; the spraying amount is 2% of the weight of the bacterial chaff raw material in step 2);

[0044] The content of the number of cells of each strain in the pyrolysis fermentation compound bacterial liquid is: 3% of Brevibacillus thermoruber (DSM 7064), 27% of Clostridium thermocellum (ATCC27405), 27% of Desulfotomaculum nigrificans (DSM 574) 20%, Geobacillus thermoglucosidasius (DSM 21625) 25%, Symbiobacterium thermophilum (DSM 24528) 25%;

[0045] 4) Pile and level off the fungus chaff raw material sprayed with pyrolysis and fermentation compound bacterial solution in step 3, the height of the pile is 80cm, carry out static fermentation for 48 hours, the temperature in the middle of the pile rises to a ...

example 3

[0053] Example 3, the same as Example 1, the difference is,

[0054] 1) The high temperature fermentation tank is 50m long, 1.6m wide and 1.1m deep.

[0055] 2) Adjust C / N to 28, moisture to 65%;

[0056] 3) Spraying the fermented pyrolysis fermentation composite bacterial liquid; the spraying amount is 2% of the weight of the bacterial chaff raw material in step 2);

[0057] The content of the number of cells of each strain in the pyrolysis and fermentation compound bacterial liquid is as follows: 5% of Brevibacillus thermoruber (DSM 7064), 25% of Clostridium thermocellum (ATCC27405), 25% of Desulfotomaculum nigrificans (DSM 574) 20%, Geobacillus thermoglucosidasius (DSM 21625) 22%, Symbiobacterium thermophilum (DSM 24528) 28%;

Abstract

The present invention relates to a method for preparing mushroom bran feed raw material by a two-step fermentation method. The method includes the following steps: collecting mushroom bran of pleurotus eryngii, flammulina velutipes and other mushrooms from industrial edible mushroom production enterprises, adding water, nitrogen, and calcium hydrogen phosphate to the mushroom bran, adjusting C / N to 25-30, spraying a fermentation compound bacteria liquid of lactobacillus plantarum, lactobacillus kimchii, lactobacillus casei and lactobacillus farciminis, carrying out high-temperature fermentation for 4 to 7 days, carrying out pile turning and stirring timely as required by a pile turning and stirring device during the high-temperature fermentation, carrying out microwave drying of the mushroom bran after the high-temperature fermentation, adding saccharose, corn flour, soybean meal powder to supply nutritional ingredients; inoculating the fermentation compound bacteria liquid of lactobacillus plantarum, lactobacillus kimchii, lactobacillus casei and Lactobacillus farciminis, and carrying out fermentation for 3 to 6 days, thereby obtaining the mushroom bran feed raw material. The mushroom bran feed raw material can be used with complete feed for preparing daily rations of cattle, sheep and the like. The mushroom bran feed raw material can also be fermented for 1 to 2 months and used as a mushroom bran fermentation raw material, can taken and used instantly, and is safe and palatable.

Description

technical field [0001] The invention relates to a method for preparing fungus chaff feed raw materials by adopting a two-stage fermentation method. Background technique [0002] Mushroom chaff is the waste left after harvesting fruiting bodies in the cultivation process of edible fungi, and is an important agricultural by-product resource. Studies have shown that after harvesting fresh mushrooms per kilogram of edible fungus culture material, there are about 0.6 kilograms of waste. In recent years, with the development of the edible fungus industry, the amount of fungus chaff resources has also increased. At present, most of the fungus chaff has not been effectively utilized, resulting in waste of resources and environmental pollution. Therefore, solving the problem of fungus chaff utilization is extremely important for the recycling of agricultural resources and the control of environmental pollution. In fact, the fungus chaff contains crude fiber, mycelium, protein and o...
