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

Abstract

The invention relates to a system for producing and cultivating liquid strains of edible fungi. The system includes a nutrient solution sterilization tank, a heat exchanger, a water chiller and several liquid strain cultivation tanks; and a nutrient solution circulation pipeline, a nutrient solution sterilization and Cooling pipeline, nutrient solution delivery pipeline, sterile compressed air inlet pipeline, sewage discharge pipeline and liquid strain delivery pipeline. The invention also discloses a method for making and cultivating edible fungus liquid strains by using the above-mentioned system. The present invention can use the residual strains in the liquid strain culture tank as the mother species for re-cultivation, avoiding the infection risk of successive inoculation, and the sterilization, cooling, transportation and supply of sterile air of the strain culture liquid are all in the airtight Completed in containers and pipelines, the chance of infection is zero. The liquid culture tank does not need to be moved, which can reduce investment, is safe and reliable, reduces labor load, and reduces labor intensity.

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
