Efficient anaerobic fermentation device for straw feed and application method thereof

Abstract

The invention provides an efficient anaerobic fermentation device for straw fee. The device comprises a supporting seat pit, a synchronous lifting mechanism, a guide heat transfer part, a heat insulation layer, a steel bottom plate, a heat preserving fermenting box body, a pressure exhausting pipe, a side surface temperature measuring sensor and a core temperature measuring sensor; the steel bottom plate and the heat insulation layer are sequentially arranged on an upper opening of the supporting seat pit; the synchronous lifting mechanism is arranged in the supporting seat pit; the guide heat transfer part and the core temperature measuring sensor are respectively inserted into guide holes formed in the steel bottom plate and the heat insulation layer by sleeving; the lower ends of the guide heat transfer part and the core temperature measuring sensor are both mounted on the synchronous lifting mechanism; the heat preserving fermenting box body is arranged above the steel bottom plate to cover the supporting seat pit; the pressure exhausting pipe is arranged on a top plate of the heat preserving fermenting box body; the side surface temperature measuring sensor is arranged on the sidewall of the heat preserving fermenting box body; the core temperature measuring sensor is arranged in a distribution area of the guide heating part. With the adoption of the device, the straws can be subjected to efficient anaerobic fermentation; the temperature in straw fermentation can be kept stable and uniform, and thus the straws can be industrially fermented into base feed.

Description

Technical field: [0001] The invention relates to feed processing equipment, in particular to feed fermentation equipment. Background technique: [0002] my country is a large agricultural country. According to online data retrieval, in 2008, my country's crop straw output was about 800 million tons, and the amount of crop straw resources ranked first in the world. The main components of crop straw are cellulose, hemicellulose, lignin and a small amount of protein. It is a clean and renewable resource. However, due to the influence of consumption concepts and lifestyles for a long time, my country's rural straw resources have been in a state of high consumption, high pollution, and low output. A considerable number of crop straws have been discarded or burned, and crop straws have not been rationally developed and utilized. , and straw burning brings serious air pollution. In recent years, with the enhancement of people's awareness of environmental protection and the further...

Problems solved by technology

[0004] Although there are many methods for producing animal feed by adding straw microbial fermentation strains and water to ferment agricultural plant straw, there is a lack of corresponding fermentation equipment, and the fermentation temperature is neither uniform nor constant, and can only be produced in small batches. Experiments and simple and rough production conditions cannot carry out industrialized production all year round, resulting in the inability of industrialized production of animal basic feed from agricultural plant straws
