Abstract
The invention relates to a cavity type negative-pressure fermentation technical process. A core principle for the technical process is that a cavity negative-pressure oxygen supply mode is used for fulfilling the aim of aerobic fermentation, so that the process is low in investment cost, convenient to operate, easy to popularize and use, efficient and energy-saving, and agricultural production and human life are served by microbial fermentation to a great extent.
Description
Technical field
The invention belongs to microorganism aerobic fermentation industry field, such as: numerous fields relevant with Civilization of Eco-farm construction to environmental pollution improvement such as organic waste processing, the processing of feces of livestock and poultry odorless and organic fertilizer production, bioenergy conversion, Collection and use, edible fungus culturing, relate to a kind of cavate negative pressure fermentation technical matters specifically.
Background technology
At present, with regard to zymotechnique requires, culture medium of edible fungus zymotechnique requires the highest, technology is relative complex and maturation also.Sum up numerous concrete fermentation patterns, by the oxygen supply mode of aerobic fermentation technical requirements, distinguish, may be summarized to be at present two large classes: the one, traditional windrow zymotechnique, oxygenation way is that the mode through repeatedly turning completes; The 2nd, from the tunnel zymotechnique technology of external introduction, its oxygen supply measure be adopt powerful device to create high pressure draft to fermentation material malleation, oxygen supply realizes, reach the object of aerobic fermentation.The former workload is large, it is inhomogeneous to ferment, discharging of low quality; The latter requires high to production site, equipment investment cost also high, be unfavorable for promoting.
Summary of the invention
The object of the invention is to overcome above-mentioned defect, a kind of cavate negative pressure fermentation technical matters is provided, this new technology central principle extremely adopts cavate negative pressure oxygen supply mode, reach aerobic fermentation object, make this technology investment cost low, easy to operate, be easy to apply, energy-efficient novel fermentation technique, the microorganism serving agriculture to a greater extent that ferments is produced and human lives.
The present invention solves the problems of the technologies described above the following technical scheme of employing:
Cavate negative pressure fermentation technical matters, is characterized in that: concrete grammar step is as follows:
1, by culture material to be fermented (or organic waste) on request proportioning mix evenly.
2, a layer plane cavity is established on ground, guarantees the gaseous interchange of bottom culture material.
3, culture material (or organic waste) is built to heap on planar cavity, in heap, construct cavity, inside establish pump-line.
4, in gas exhaust duct, establish an exhaust equipment.While needing oxygen supply in fermenting process, start exhaust equipment, make intraperitoneal produce negative pressure, make fresh air enter equably stockpile for organism of fermentation action need by the gap of culture material.
5, at culture material, enclose sealed plastic booth outward, rise heat, insulation effect, communicate with the external world if desired and regulate air condition in canopy.
The invention has the beneficial effects as follows:
In many solid fermentation industries, what technical requirement was the highest is the fermentation of culture medium of edible fungus, and with regard to the sector, the advantage of cavate zymotechnique is very obvious, and the advantage in practice is used embodies as follows:
(1) with the comparison of conventional Secondary Fermentation technology: the time is short, recruitment is few, effective, energy-saving and environmental protection.
(2) with the technique comparison of tunnel fermentation: in the primary fermentation stage, the oxygen supply of cavate zymotechnique is more even, and humidity, temperature are relatively constant, and fermentation evenly; And high pressure oxygenation way can destroy the stable of gas channel, affect primary fermentation uniformity coefficient; From cost of investment and technical threshold, cavate fermentation technique advantage is very obvious, has very strong popularization, using value.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the present invention is described further
Accompanying drawing 1 is the on-the-spot schematic diagram of cavate negative pressure fermentation technical matters of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, cavate negative pressure fermentation technical matters of the present invention is further described.
Cavate negative pressure fermentation technical matters, concrete grammar step is as follows:
1, by culture material to be fermented (or organic waste) on request proportioning mix evenly.
2, a layer plane cavity is established on ground, guarantees the gaseous interchange of bottom culture material.
3, culture material (or organic waste) is built to heap on planar cavity, in heap, construct cavity, inside establish pump-line.
4, in gas exhaust duct, establish an exhaust equipment.While needing oxygen supply in fermenting process, start exhaust equipment, make intraperitoneal produce negative pressure, make fresh air enter equably stockpile for organism of fermentation action need by the gap of culture material.
5, at culture material, enclose sealed plastic booth outward, rise heat, insulation effect, communicate with the external world if desired and regulate air condition in canopy.
Following table is technique and the comparative data of the present invention of common process and tunnel fermentation:
Above-described embodiment, the present invention embodiment a kind of more preferably just, the common variation that those skilled in the art carries out within the scope of technical solution of the present invention and replacing all should be included in protection scope of the present invention.
Claims (1)
1. cavate negative pressure fermentation technical matters, is characterized in that: concrete grammar step is as follows:
(1), by culture material to be fermented (or organic waste) on request proportioning mix evenly;
(2), a layer plane cavity is established, the gaseous interchange of assurance bottom culture material in ground;
(3), culture material (or organic waste) is built to heap on planar cavity, in heap, construct cavity, inside establish pump-line;
