Embodiment 2

[0038] Embodiment 2: Composite strain fermented soybean hull comparative test

[0039] Step 1: Composite bacterial liquid production. The bacterial strain is composed of Penicillium oxalicum, lactic acid bacteria, Bacillus natto, and Candida ruthenicum, which are mixed according to the volume fraction ratio of 2:1:2:1 (in the fermentation broth).

[0040] Step 2: Culture medium production: Mix the compound bacterial solution evenly into the soybean hull feed to be fermented according to the proportion, and add the inoculum according to the weight fraction of 10%; the soybean hull addition ratio in the soybean hull feed solid-state fermentation medium is 90%, and the The nitrogen source is urea, and the addition ratio is 1.5% by weight fraction; the inorganic salt is disodium hydrogen phosphate and calcium carbonate, and the addition ratio is 0.2% and 0.3% by weight fraction, and fully stirred.

[0041] Step 3: Loading: Put the processed soybean hull feed to be fermented into ...

Embodiment 3

[0048] Embodiment 3: Composite strain fermented grape seed meal comparison test

[0049] Step 1: Composite bacterial liquid production. The bacterial strain is composed of Penicillium oxalicum, lactic acid bacteria, Bacillus subtilis, and Saccharomyces cerevisiae, which are mixed according to the volume fraction ratio of 3:1:2:1 (in the fermentation broth).

[0050] Step 2: Culture medium production: Mix the compound bacterial solution evenly into the grape seed meal feed to be fermented according to the proportion, and add the inoculation amount according to the weight fraction of 20%; the grape seed meal addition ratio in the solid fermentation medium of the grape seed meal feed is 80% , bran is 20%; the nitrogen source is ammonium nitrate, the addition ratio is 2.0% by weight fraction; the inorganic salt is disodium hydrogen phosphate and calcium carbonate, the addition ratio is 0.2% and 0.1% by weight fraction, and fully stirred.

[0051] Step 3: Loading: Put the processe...

Abstract

The invention provides a high fiber forage biodegradation fermenting system suitable for multi-bacterial composite fermentation, and solves the key problems in production that charging / discharging in a fermentation process is large in labor intensity, fermentation period is long, output is low, fermentation effect is poor and fermentation conditions are hard to control. The high fiber forage biodegradation fermenting system provides a novel fermentation chamber and matching facility, wherein a semi-automatic fermentation vehicle is designed in the fermentation chamber, and the vehicle is good in air permeability, convenient for loading and unloading, more in bearing material, and convenient in motion and discharging; the fermentation chamber is excellent in sealing, can realize automatic temperature control, automatic moisture control, and automatic disinfection; the system is large in single fermentation capacity, convenient in operation, short in fermentation period, and saves energy; the fermentation system saves time and labor, saves energy, and fermentation conditions can be easily controlled, thus better satisfying factory forage fermentation production needs.

Description

technical field [0001] The patent of the present invention relates to the technical field of microbial fermented feed equipment, in particular to a high-fiber feed biodegradable fermentation device. Background technique [0002] Fermentation equipment is the most critical infrastructure for bio-feed production. At present, industrialized feed solid-state fermentation reactors often have the following types: one is bagged, the other is wooden box, and the third is shallow plate. The first type of fermentation device has the advantages of simple structure and low cost, but its disadvantages are poor ventilation, low production efficiency, and high labor intensity. It is difficult to meet the needs of fermentation characteristics of different strains by adopting composite strain fermentation. Using this method to ferment high-fiber feed, The strains only grow in the early stage of fermentation, and the strains no longer grow due to the limitation of fermentation conditions in ...
