Description

Technical Field

[0001] The invention relates to the technical field of edible fungus liquid strain breeding, and more specifically to an edible fungus liquid strain multi-tank breeding device. Background Art

[0002] The cultivation of strains adopts aseptic operation methods to separate edible fungi from mixed microorganisms. This process is called strain separation. The mycelium obtained from the separation process is purified to become a pure strain. The method of artificially growing and reproducing pure strains in large quantities under laboratory conditions is called strain cultivation.

[0003] In the production of edible fungi, liquid strains are being adopted by more and more companies due to their advantages such as short culture cycle, low cost and strong strain vitality. However, the current liquid strain production equipment and production process have problems such as small culture containers, limited one-time fermentation volume, and difficulty in supporting the factory-based and large-scale production of the edible fungi industry. With the increasing scale of edible fungi production, this contradiction between supply and demand has become more and more prominent and has become a bottleneck problem in the factory-based production of edible fungi.

[0004] The patent with publication number CN109328883B discloses a culture device for edible fungi strains and a method for cultivating edible fungi strains, including an open box, in which a first culture chamber and a second culture chamber are formed by a partition, the first culture chamber is provided with a culture medium sterilization device and a strain culture device, the second culture chamber is provided with an air purification device, and the entire culture box is provided with a culture medium sterilization device and a strain culture device, which can transfer the sterilized culture medium to the strain culture device in time for cultivating edible fungi strains, thereby avoiding secondary contamination of the culture medium affecting the cultivation of edible fungi strains.

[0005] The patent with publication number CN109429912A discloses a liquid spawn cultivation device for Pleurotus eryngii, including a shell, a resistance heating plate and a semiconductor resistor plate are installed on the inner back side of the shell, shafts are rotatably installed on the left and right sides of the inside of the shell, the shafts on the right side penetrate the shell and are connected to pulleys, a swing device is installed on the lower right side of the shell, one end of the second water supply pipe penetrates the shell and the water storage frame, fixed blocks are symmetrically installed on both sides of the inside of the shell, a guide shaft is fixedly installed between the two corresponding fixed blocks, a cultivation device is installed between the two corresponding sliders, and an air supply device is installed on the left side of the outside of the shell.

[0006] However, the traditional single-tank strain cultivation device cannot carry out large-scale strain cultivation due to its long breeding cycle and limited capacity, and cannot meet the needs of large-scale and industrialized development of edible fungi. When large-scale strain cultivation is required, it can only be achieved by increasing the number of tanks. Under suitable conditions, liquid strains can reproduce very quickly. However, taking shiitake mushrooms as an example, the breeding cycle of liquid strains in a 600L single-tank environment requires 8-12 days. Therefore, single-tank breeding of liquid strains has the common industry pain point of inconsistent strain age. If liquid strains are cultivated in part, they are taken out manually and placed in a larger strain cultivation device for cultivation. During the transfer process, the breeding environment will change and the strains cannot be controlled from being contaminated.

[0007] Therefore, how to provide a large-tonnage multi-tank breeding device for liquid edible fungi strains, meet the current large-scale and industrialized production of edible fungi through the combined cultivation of large-tonnage multi-tanks, and enable the strains to automatically flow to the next cultivation environment after cultivation is completed is a problem that technical personnel in this field urgently need to solve.
