High-pressure aerobic fermentation equipment and fermentation method

Abstract

The invention provides high-pressure aerobic fermentation equipment. The high-pressure aerobic fermentation equipment comprises a plurality of splicing units, wherein each splicing unit comprises a cabinet type structure and each cabinet type structure comprises a front side face with an opening / closing structure, an upper end face provided with a plurality of air exhausting structures and a lowerend face for placing a fermentation material; a plurality of grooves are formed in the lower end face; each groove is internally provided with a high-pressure aerobic ventilation device; each high-pressure aerobic ventilation device is connected with an air compressor. According to the high-pressure aerobic fermentation equipment provided by the invention, construction is not needed and the equipment is suitable for agricultural protection fields which are not suitable for the construction; the equipment can be used while being plugged, and gas can be supplied for aerobic fermentation when apower supply is switched on; the equipment can be combined randomly, and building block type splicing combination is adopted; the high-pressure aerobic fermentation equipment can be suitable for the aerobic fermentation of fields including agricultural bases, small-scale livestock manure composting, feed fermentation, mushroom ground beds, leftover garbage, wood dreg, community plant fallen leavesand the like.

Description

technical field [0001] The invention relates to the field of microbial fermentation, in particular to a high-pressure aerobic fermentation equipment and a fermentation method. Background technique [0002] Aerobic fermentation is a process in which microorganisms use oxygen to decompose organic matter, and at the same time generate fermentation heat to promote decomposing and water evaporation; in this process, it is necessary to ensure that the microorganisms in the to-be-fermented heap can combine with oxygen in order to carry out aerobic fermentation Transformation process; the difference between anaerobic fermentation and aerobic fermentation lies in the oxygen concentration in the heap to be fermented. Specifically, when the oxygen concentration is below 3%, it is anaerobic fermentation; when the oxygen concentration is above 10%, it is the aerobic fermentation with the best degradation effect; % above the degradation rate will be reduced by 50%. Since aerobic ferment...

AI Technical Summary

Problems solved by technology

In the way of natural ventilation, it is often necessary to expose the microorganisms in the pile to be fermented to oxygen through turning over the pile, because the oxygen concentration in the pile to be fermented cannot be accurately measured at any time, and the interval between turning time points is not easy to standardize, which is easy to cause Anaerobic fermentation and aerobic fermentation are constantly switching, and stench will be generated when the pile is turned; forced air supply must ensure that the body of the pile to be fermented can be in contact with oxygen evenly, and because the oxygen concentration in the pile to be fermented cannot be accurately measured at any time, the gas supply And the time interval of non-gas supply is not easy to standardize. In order not to cause doubts about the continuous conversion between aerobic fermentation and anaerobic fermentation like natural ventilation, uninterrupted gas supply will be adopted as much as possible, but also because microbial degradation requires a certain degree Moisture, uninterrupted air supply will make the pile near the air supply port too dry and cannot be effectively degraded, resulting in incomplete fermentation

[0003] And the current fermentation device needs civil construction, which is inconvenient to move and splice
