Thick-layer ventilation belt type fermentation machine

Abstract

The invention discloses a thick-layer ventilation belt type fermentation machine. The thick-layer ventilation belt type fermentation machine comprises a machine box, a ventilation opening formed in the top side of the machine box and a multi-layer conveying mechanism transversely arranged in the machine box. The running directions of the adjacent conveying mechanisms are opposite, and the starting ends and the stopping ends are staggered by a certain distance; a bearing surface of the conveying mechanism is provided with a temperature sensor in the same conveying direction as the bearing surface, and a non-bearing surface is provided with an air duct system; the air duct system comprises a draught fan and an air volume controller used for adjusting the air volume of the draught fan according to the temperature measurement height of the temperature sensor. The material temperature is monitored in real time by configuring the temperature measuring cable consistent with the material advancing direction, and the temperature measuring cable is in communication connection with the fan controller, so that the air volume of the fan is controlled in real time along with the material temperature, and the fermentation material temperature is consistent with the optimal growth temperature of fermentation strains.

Description

technical field [0001] The invention relates to the field of feed fermentation equipment, in particular to a thick-layer ventilated belt-type fermentation machine. Background technique [0002] At present, fermented feed is getting more and more recognition in the breeding industry, and fermented soybean meal, fermented distiller's grains and other fermented feeds have obtained good development opportunities. Fermentation methods are divided into anaerobic fermentation and aerobic fermentation. Among them, anaerobic fermentation is not easy to contaminate miscellaneous bacteria, and is easy to operate, but there are disadvantages such as insufficient fermentation and decomposition force and insufficient number of bacterial reproduction; aerobic fermentation has the advantages of fast fermentation speed, complete antigen decomposition, and no accumulation of fusel alcohols and miscellaneous acids. However, due to its susceptibility to contamination by bacteria and complicate...

Problems solved by technology

Among them, anaerobic fermentation is not easy to contaminate miscellaneous bacteria, and is easy to operate, but there are disadvantages such as insufficient fermentation and decomposition force and insufficient number of bacterial reproduction; aerobic fermentation has the advantages of fast fermentation speed, complete antigen decomposition, and no accumulation of fusel alcohols and miscellaneous acids. However, due to its susceptibility to contamination by bacteria and complex ventilation and heat dissipation operations, its development has been slow

[0003] Belt fermentation equipment is suitable for solid-state aerobic fermentation process. Most of the materials are ventilated on the surface, which can achieve continuous production, but there are the following problems: the surface of the material is ventilated, which is prone to insufficient oxygen supply and poor fermentation uniformity; it is not suitable for thick-layer materials. Oxygen fermentation, the material thickness exceeds 300mm, and the temperature difference between the upper and lower layers can reach more than 10°C, which seriously reduces the fermentation quality; because it is not suitable for thick layer material fermentation, the fermentation efficiency is also very low
