Embodiment Construction

[0023] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0024] A preparation method and device for liquid strain of Pleurotus eryngii, characterized in that:

[0025] The preparation method of liquid spawn is:

[0026] 1. Proportion of liquid culture medium: by weight percentage, potato 20, wheat bran 15, brown sugar 3, glucose 1, peptone 01, potassium dihydrogen phosphate 0.5, magnesium sulfate 0.05, vitamin B 0.05, vegetable oil 0.01, and the rest The quantity is water, the pH value is 7.5.

[0027] 2. Preparation of material liquid: follow the following order

[0028] ①Make potato juice and bran juice: dig fresh potatoes, peel and wash, cut into slices or strips about 4cm thick, add 5 times the water and boil until crispy, filter with 6-8 layers of gauze, and take the juice for later use. Add fresh, mildew-free bran to 10 times the water and boil for 20 minutes, then filter to get the juice for later u...

Abstract

The invention discloses a method and a device for preparing a pleurotus eryngii liquid strain. The method for preparing the liquid strain comprises the following step of: 1, preparing liquid strain culture medium from the following materials in percentage by weight: 15 to 25 percent of potato, 5 to 15 percent of wheat bran, 1 to 5 percent of brown sugar, 0.5 to 3 percent of glucose, 0.2 to 1.5 percent of peptone, 0.2 to 1.5 percent of potassium dihydrogen phosphate, 0.05 to 0.3 percent of magnesium sulfate, 0.05 to 0.3 percent of vitamin B, 0.01 to 0.05 percent of plant oil and the balance of water, wherein the pH value is 5.0 to 8.0. An air purification device provided by the invention is formed by arranging an oil-free air compressor at an outdoor front air supply end; a filter membrane with small aperture is selected; double filtration is performed on air by air intake and air outtake, and the air then is fed in an air storage tank and then fed in an indoor branch cylinder through a pipeline, passes through a reducing valve, is filtered and fed in each fermentation tank through a filter of the fermentation tank; in this way, the outdoor air is filtered for several time to become clean and aseptic fresh air which is fed in the fermentation tank; and thus the clean air required for fermentation culture of the liquid strain in the tank can be effectively ensured, and the preparation of the liquid strain is facilitated.

Description

Technical field: [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a preparation method and equipment for industrially producing liquid strains of edible fungi. Background technique: [0002] Liquid strain production technology is a new production method in the production of edible fungi. It is the application of biological fermentation technology in agricultural production. With the development of edible fungus production technology and the scale, industrialization and modernization of production, the production technology of liquid bacteria will have more and more extensive application value. [0003] Production of liquid strains According to the nutritional requirements of edible fungus mycelia, prepare liquid medium, use liquid strain culture tanks and matching production processes, and artificially set the environment required for the growth and development of edible fungus mycelia in liquid culture tanks Pa...
