Abstract
A traditional edible fungi culturing material air storage fermentation method lasts 20-25 days for fermenting and multiple times for turning, thus being time-consuming and labor-consuming. The invention discloses a multibore tunnel type continuous fermentation method of an edible fungi culturing material, comprising the following steps: adding microbial fermentation agent into a culturing material for prefermenting 3-5 days; transmitting the prefermented culturing material into a multibore tunnel type fermenting chamber (1) to be naturally heated for 6-9 hours; adding the needed EM bacterial strain to the culturing material to promote the conversion of nutrient substances; conveying the steam to the fermenting chamber from a basement (3) through evenly distributed steam tunnel holes (4); the culturing material can be heated rapidly and evenly, and has good pasteurization effect. The total fermenting time only lasts 10-12 days; generally, one fermenting chamber can ferment 10-15 tons of the culturing material at a time, enjoying high production efficiency; if a plurality of fermenting chambers are used in series, the culturing material can be supplied continuously every day, thus satisfying continuous needs of culturing edible fungi, and obtaining good economic and social benefits.
Description
Technical field
The invention belongs to the edible fungus culturing production technical field, relate to a kind of fermentation process of culture medium of edible fungus, particularly a kind of multibore tunnel formula continuous ferment process of culture medium of edible fungus.
Background technology
At present, edible fungus culturing mainly is that unit carries out distributed seasonal cultivation with the peasant household, and the fermentation technique of culture material falls behind, and fermentation mode is simple, adopts the method for culture material fermentation reactor system usually.The fermentation time of traditional fermentation reactor system method is 20～25 days, and need carry out repeatedly turning, and fermentation condition is wayward, and culture material easily is bacterial contamination, and ferment effect is poor, and edible fungus culturing annual a kind of is received, and mushroom canopy utilization ratio is low.Application number is the tunnel frame compost fermentation method that 200910042556.6 patent of invention discloses a kind of culture medium of edible fungus; this method has been improved fermentation condition to a certain extent; but this method implementation cost height; technology is complicated; fermentation time is long, can not adapt to the uninterrupted demand of producing culture material of mass-producing of edible mushrooms.
Summary of the invention
The invention discloses a kind of multibore tunnel formula continuous ferment process of culture medium of edible fungus; overcome traditional culture material fermentation reactor system method cycle grow, yield poorly, fermentation condition is wayward and culture material such as easily is bacterial contamination at defective, the tunnel frame compost fermentation method cost that has improved present disclosed a kind of culture medium of edible fungus simultaneously is higher, complex process, be unfavorable for deficiencies such as large-scale production.The present invention can effectively control fermentation condition, has shortened the fermentation period of culture material greatly, has reduced production cost, can realize that the mass-producing of culture material fermentation is uninterruptedly produced.
The present invention solves the technical scheme that its technical problem takes: a kind of multibore tunnel formula continuous ferment process of culture medium of edible fungus, its fermenting process is: at first in fermentor tank required EM bacterial strain is carried out enlarged culturing, simultaneously culture material is carried out the outdoor pre-fermentation of heap of building, fermentation time is 3～5 days.Culture material after will fermenting in advance then changes the fermentation 6～9 hours that heats up naturally in the multibore tunnel formula proving room (1) over to, afterwards the EM bacterial strain after cultivating is added in the culture material, to promote nutritive substance to transform, carry out Secondary Fermentation, utilize external centrifugal blower (6) and vent fan (7) that proving room is ventilated during fermentation and lower the temperature, regulate humidity by humidifier (2).Fermentation time is about 7 days, uses forklift machinery turning 1～2 time midway.The culture material total fermentation time is 10～12 days, only is half of traditional zymotic method, and the production efficiency of culture material doubles.
Described EM bacterial strain enlarged culturing is carried out in fermentor tank, adopts the deep liquid culture technique that required EM bacterial strain is cultivated, and incubation time is 3 days.The outdoor heap mode of building is adopted in the pre-fermentation of culture material, adopt the mode of spray to prewet major ingredients such as forage, cow dung, cotton seed hulls earlier, mix auxiliary materials such as terra alba, calcium superphosphate, urea, lime next day again with microbial starter culture, the usage quantity of starter is that per 1000 kilograms of culture materials add 1～1.2 kilogram, stir then, add in the major ingredient.Controlled temperature is at 20～30 ℃, and humidity is 80～90%, and pH is between 8～9, and overlay film fermented 3 days.Described Secondary Fermentation heated up 6～9 hours earlier naturally, utilized heat of fermentation to finish pasteurize.Every day early, evening starts centrifugal blower (6) respectively and exhaust fan (7) was worked 2～3 hours, can realize air cycle in the proving room, regulates the temperature of culture material fermentation, in time with the waste gas discharge that forms in the proving room, and provides oxygen.Utilize humidifier (2) to regulate humidity.Usually the control leavening temperature is at 65～75 ℃, and humidity is 70～75%.
Described multibore tunnel formula proving room (1), hole, dense distribution steam tunnel, ground (4), aperture, tunnel 2～2.5cm, Kong Yukong width between centers is 8～10cm; Snakelike steam heating pipe (5) is set in the vault (3).Snakelike steam heating pipe (5) is connected to high compressed steam boiler (8), and steam pipeline is provided with by-pass valve control (9), can regulate steam operational throughput size, can effectively control the proving room temperature.
The multibore tunnel formula continuous ferment process of a kind of culture medium of edible fungus of the present invention, but a common proving room is 10～15 tons in fermentation culture material once, the production efficiency height, if several proving room series connection are used, then can realize culture material without interruption every day, be well positioned to meet the demand of the annual uninterrupted cultivation of edible mushrooms, can obtain good economy and society benefit culture material.
