Aerobic solid-state fermentation system

Abstract

The invention discloses an aerobic solid-state fermentation system, a fermentation rack body (1) is arranged inside a fermentation chamber, a steam generator, a bacteria strain can, a high-pressure water pump, an air filter and an air compressor are arranged outside the fermentation chamber, the fermentation rack body (1) is internally provided with a tray (6), a spraying device (10) is arranged above the tray, the spraying device is connected with a first reversing valve through a connecting pipe (3), the first reversing valve is connected with the steam generator, the bacteria strain can, the high-pressure water pump and the air filter through a pipeline, the air compressor is connected with a second reversing valve, the second reversing valve is connected with the bacteria strain can and the air filter through a pipeline. The aerobic solid-state fermentation is carried out in a confined space, inoculation and fermentation processes are sealed without the need to enter the fermentation chamber, so that mixed bacteria in the fermentation process contamination can be avoided, inoculation moisture and air can be transported and enter into a fermentation device together with high temperature steam by the same pipeline, pollution caused by unhygienic pipelines can be effectively prevented, moisture and air can be timely and conveniently introduced from the outer side of the fermentation chamber, and the fermentation process is more uniform and efficient.

Description

technical field [0001] The invention relates to a fermentation system, in particular to an aerobic solid fermentation system. Background technique [0002] At present, in the process of aerobic solid fermentation, steps such as high-temperature sterilization and inoculation are required. Most of these operations require people to enter the fermentation room for operation. The frequent opening of the fermentation room and the entry and exit of operators will cause bacterial contamination during the fermentation process; in addition , in a large-scale fermentation room, the manual inoculation process has a large workload. In order to meet the air and humidity required for the growth of microorganisms, it is also necessary to regularly feed sterile air and water into the fermentation tank, which is complicated and inefficient. . Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides an aerobic solid...
