Problems solved by technology

However, if the liquid bacteria are infected with bacteria in the late stage of fermentation, or the amount of bacteria is very small, or the infected bacteria have no abnormal smell, etc., it is difficult for technicians to judge pollution according to conventional methods, resulting in the flow of contaminated bacteria into production and huge losses.

Embodiment 1

[0039] Below in conjunction with accompanying drawing, illustrate edible fungus liquid strain fermenter of the present invention.

[0040] Edible fungus liquid spawn fermenter is made of air filtration system, main tank 5, auxiliary tank 12 and sampling pipeline 10.

[0041] Wherein, the air filtration system is composed of an air intake pipe 1, a bacterial filter 2 and a quick connector 4, wherein the air intake pipe 1 is connected with a pressure gauge 3;

[0042] The main tank 5 is a fermenter commonly used for edible mushroom liquid strains, and its whole is made of stainless steel with a thickness of 1cm. There are tank lids 17 and exhaust ports 9 on the top of the tank, handles 6 and main tank windows 7 are arranged on the tank body, and the tank lids are tightly closed. Fixed screw 8 is sealed and fixed on the top of the main tank. There are four wheels 20 at the bottom, which are used for fixing and moving the fermenter.

[0043] The auxiliary tank 12 is made of stai...

Embodiment 2

[0046] Take the industrialized production of crab-flavored mushroom liquid strain production process as an example.

[0047] Adopt the fermentor of embodiment 1, the prepared fermenter is carried out the substratum preparation, wherein the substratum in the main tank is prepared according to the routine formula of the industrial production liquid bacterial classification of crab-flavored mushroom, the test substratum in the sub-tank is : Mix 0.35% of soybean meal powder and corn flour through a 120 mesh sieve (mixed according to 1:1 weight ratio), 0.25% of glucose, 0.3% of yeast extract powder, 0.6% of peptone, 0.6% of sodium chloride, 0.4% of 1% phenol red solution %, distilled water 1000mL, pH6.8-7.2. Close the switch valve 11 of the sampling pipeline 10, prepare 100ml test medium, and inject it into the auxiliary tank 12 of the test fermenter. After the main tank 5 and the auxiliary tank 12 are sealed, they enter the autoclave with the help of the wheels 20 at the bottom o...

Abstract

The invention provides an edible fungus liquid spawn fermentation tank and application thereof. The edible fungus liquid spawn fermentation tank comprises a ventilation filter system, a main tank, an auxiliary tank and a sampling pipe. The edible fungus liquid spawn fermentation tank can be used for detecting whether edible fungus liquid spawns are contaminated in the cultivation process any time; the result indication can be judged directly, and the problem that contaminated spawns enter production because of manual misjudgment of observers is solved.

Description

Technical field: [0001] The invention relates to the technical field of industrial production of edible fungi, in particular to a fermenter for edible fungus liquid strains and an application thereof. Background technique: [0002] Edible mushroom liquid strain technology has become one of the technical hotspots in the edible fungus industry in recent years due to its advantages such as simple production process, short production cycle, low production cost and high strain quality. Previous inventions mostly focused on the cultivation conditions, medium components and related production steps of liquid strains of different edible fungus varieties, but the real application bottleneck of liquid spawn technology lies in the effective control of contaminated liquid strains from flowing into production. [0003] In the actual production process, many industrial enterprises of edible fungi have been unable to predict whether the liquid strains are contaminated before use, which has...
