System and method for producing and culturing liquid spawns of edible fungus

Abstract

The invention discloses a system and a method for producing and culturing liquid spawns of an edible fungus. The system comprises a nutrient solution sterilized tank, a heat exchanger, a cooling-water machine set and a plurality of liquid spawn culture tanks, and further comprises a nutrient solution circulation pipeline, a nutrient solution sterilization and cooling pipeline, a nutrient solution conveying pipeline, a germ-free compressed air inlet pipeline, a blow-off pipeline and a liquid spawn conveying pipeline. The invention further discloses a method for producing and culturing the liquid spawns of the edible fungus by using the system. According to the system and the method provided by the invention, residue spawns in the liquid spawn culture tanks can be used as stock cultures for again culture, so that the infection risks due to successive vaccination can be avoided; the sterilization, the cooling, the conveying and the germ-free air supply of the spawns are completed in inclosed vessels and pipelines, so that the infection probability is zero; the movement of the liquid spawn culture tanks is avoided, so that the investment is reduced, safety and reliability are realized, the amount of used labor is reduced, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to a system for making and cultivating strains, in particular to a system for making and cultivating liquid strains of edible fungi; the invention also relates to a method for making and cultivating liquid strains of edible fungi using the system. Background technique [0002] In the prior art, the production of edible mushroom liquid strains all adopts independent equipment, and its production mode is: [0003] First, the liquid strain culture tank is manually cleaned in the strain tank cleaning room. After cleaning, the liquid strain culture tank is manually pushed into the batching room of the liquid strain culture tank. Manually pour the prepared culture solution and clear water into the liquid strain culture tank. Then manually push the liquid strain culture tank into the strain tank sterilizer to sterilize. After the sterilization is completed, the liquid strain culture tank is manually pulled out from the strain tank ste...

AI Technical Summary

Problems solved by technology

[0007] 1. High work intensity: Since each strain culture tank needs to be installed with movable wheels and manually pulled and carried, the total weight can only be less than one ton, or it is difficult to drive by manpower;

[0008] 2. High infection rate: Each strain tank needs 3 times of plugging, dismantling of the sterile air connector, 1 plugging of the strain output pipe connector, and opening of the inoculation quick-opening cap for inoculation in a culture cycle

The above process must be completed under sterile conditions, and requires the staff to be very skilled, otherwise it is very easy to cause infection;

[0009] 3. High investment cost

[0010] 4. The water consumption is large, and the tap water keeps spraying the strain tank during cooling, which flows in vain and cannot be recycled, resulting in waste
