Abstract
The utility model relates to an edible fungus liquid strain culture device. The edible fungus liquid strain culture device comprises a first-stage fermentation bottle, a second-stage fermentation tank, a liquid culture medium inlet and outlet tube, a gas inlet tube and a gas outlet tube, wherein a test tube for inoculation is inserted on a closed bottle stopper of the first-stage fermentation bottle, the test tube for inoculation is bottomless, a wire mesh is arranged at the bottom of the test tube for preventing strains from falling into a liquid culture medium, and a gas-permeable stopper is plugged at a tube mouth; and a tee is arranged on a connecting tube for connecting the first-stage fermentation bottle, the second-stage fermentation tank and the liquid culture medium inlet and outlet tube for preventing the liquid culture medium in the first-stage fermentation bottle from overflowing due to gas pressure during sterilization, and the other end of the tee is connected with a gas supply pump via a filter. The first-stage fermentation bottle is a 5L glass bottle, the culture quantity of the first-stage liquid strains is large, the success rate is much higher than that of similar equipment at home and abroad, and the equipment has low price; and the strains are firstly inoculated into the test tube where the bottle stopper is plugged, separated from the liquid culture medium and completely exposed in air, and after a large number of small and tender mycelia are formed, the small and tender mycelia are further placed into the liquid culture medium for deep culture, and the culture effect is excellent.
Description
Technical field
The culture device for liquid strain of edible fungus of the utility model and a kind of optimization.
Background technology
Edible Fungi presents the development trend of batch production, intensification and fluidization at present.Traditional edible mushroom solid spawn planting type is long owing to the production cycle, the agricultural labour intensity of mushroom is not suitable for large-scale production greatly.And the edible fungi liquid strain planting type because with short production cycle, the agricultural labour intensity of mushroom is little, very the batch production of edibility bacterium is cultivated on a large scale.But the edible fungi liquid strain of China uses present situation unsatisfactory: the one, and the liquid spawn production technology is unreasonable, and it is low to produce power continuously; The 2nd, liquid production of hybrid seeds equipment price is too expensive, and most of mushroom farming is unwilling or unable purchase; The 3rd, there is design defect in the product that a lot of edible fungi liquid strain device fabrication producer releases, possibly successfully not produce liquid spawn continuously.Reality is that though edible fungus liquid simple seed production equipment promoted for two more than ten years, the winner is still very few, the idle in a large number ornaments that become of the edible mushroom stainless steel fermentation tank of promoting since 2002.
The culture apparatus that uses at present, the special-purpose training method of planting of level liquid has had three kinds of modes now, a kind of is machinery or electromagnetism shake-flask culture, have that shaking flask inoculation kind mouth is big, the cultivation amount less, the too poor problem of success rate; Two kinds is to cultivate a large amount of wood chip bacterial classifications, directly adds water and blends to pour in the fermentation tank and cultivate, and has that big, the implicit assorted bacterium of sowing quantity is difficult to check, the problem of successful rate variance; Three kinds is to plant mother to insert the one grade fermemtation bottle, exists the fermentation flask inoculation mouthful big, the problem that pollution risk is big, and also the bacterial classification that connects is immersed in the liquid, and the young tender mycelium of static cultivation generation is few, influences liquid bacterium training quality.What kill most is, in inoculating hood or sterile working platform, inserts pipeline fermentation flask and fixedly during bottle stopper, is difficult to the generation that control is polluted.Level liquid kind or special mother kind are transferred into the operation of second order fermentation jar, and dual mode has been arranged now, and the one, utilize the one-level kind flame protection to pour fermentation tank into, operation easier is big, and success rate is not high; The 2nd, after the sterilization cooling, in inoculating hood or sterile working platform, be connected the one-level bottle with the second order fermentation jar, be pressed into the second order fermentation jar to the one-level kind along closed conduit, in case connecting, pollutes formerly in pipeline, though be thereafter closed-loop operation, pollute also just inevitable.So research and develop a kind of cheap, reliable and stable, simple to operate edible fungus liquid production of hybrid seeds equipment, seeming presses for day by day.
Summary of the invention
The purpose of the utility model is a kind of culture device for liquid strain of edible fungus of design, to solve the problem that prior art exists.
Realize that the technical scheme that the utility model purpose is taked is: this culture apparatus comprises one grade fermemtation bottle, second order fermentation jar, liquid nutrient medium turnover pipe, air inlet pipe, escape pipe; Its key is; Be inserted with an inoculation beyond the Great Wall at the sealing bottles of one grade fermemtation bottle and use test tube, inoculation does not have the end with test tube, and the bottom is provided with a gauze; Can prevent that bacterial classification from falling into liquid nutrient medium, the mouth of pipe is plugged with ventilative plug; On the tube connector that connects one grade fermemtation bottle and second order fermentation jar liquid nutrient medium turnover pipe, be provided with a threeway, can prevent that when sterilization the threeway other end is through a filter connection air feed pump because gas pressure causes in the one grade fermemtation bottle liquid nutrient medium excessive.
The good effect of the utility model is: the one grade fermemtation bottle is 5 liters a vial, and the level liquid bacterial classification amount of cultivation is big; The inoculation mouth is exactly the test tube mouth, need not pull out one grade fermemtation bottle bottle stopper, and is directly numerous with the expansion of test tube kind, so one grade fermemtation bottle graft kind success rate is higher than domestic and international same category of device far away; Insert bottle stopper to bacterial classification earlier and insert in vitro, break away from liquid nutrient medium, be exposed to fully in the air, behind a large amount of young tender mycelium of formation, put into the liquid nutrient medium deep layer again and cultivate, culture effect is splendid; Equipment connects all to be accomplished before sterilization, had effectively avoided the pollution that causes because of the attended operation error; Equipment price is cheap, and now 100 liters of jars are often only cultivated 60-70 and risen liquid spawn on the market, and about 20,000 yuan of prices; Only 150 yuan of this device prices; Also can cultivate 60-70 and rise liquid spawn, price be on the market the stainless cylinder of steel of same specification 1%, cost descends 99%.
