Straw fermentation equipment

Abstract

The invention provides straw fermentation equipment which includes a humidification tank and a fermentation tank. The humidification tank and the fermentation tank are in separated type, and a straw cutting mechanism is arranged in the humidification tank. The straw cutting mechanism can evenly cut straws. The humidification tank is further internally provided with a humidifier, the fermentation tank is internally provided with an oxygen exhaust device and a constant temperature device, the oxygen exhaust device can discharge oxygen in the inner cavity of the fermentation tank, and the constant temperature device can keep the temperature of the inner cavity of the fermentation tank constant within a preset range. The batch small-volume fermentation can be realized through the separated type humidification tank and fermentation tank, and the production efficiency and storage effect are improved; through the setting of the oxygen exhaust device, the highest degree of anaerobic in the fermentation tank can be realized, and therefore superior conditions are provided for anaerobic fermentation; and the problems of poor fermentation quality, long fermentation time, short storage time andthe like due to most of the current fermentation devices cannot meet the micro-storage process conditions at the same time are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of straw fermentation equipment, and in particular relates to straw fermentation equipment. Background technique [0002] Straw fermentation is the microbial fermentation and storage technology of crop straw, which is a straw treatment method to improve the nutritional value of crop straw. The straw micro-storage technology promotes the decomposition of straw cellulose, hemicellulose and lignin under airtight anaerobic conditions by adding lignocellulose starter, improves the palatability of straw, increases its digestibility, and increases nutrition. The straw micro-storage processing crop straw has the characteristics of high output, low cost, fast weight gain, and non-toxicity. It can be used as a new technology for processing straw. The feed produced is widely used in the feeding of herbivorous livestock. The successful application of this technology has opened up a new way for the effective use of crop...

AI Technical Summary

Problems solved by technology

[0008] From the above successful conditions of straw micro-storage, it can be known that straw fermentation has relatively high requirements on the environment and equipment, but in the current technical field of straw fermentation equipment, most of them cannot meet the above-mentioned process conditions at the same time, so that the fermentation quality is not good. Problems such as long fermentation time and short storage time appear
