Technical Field

[0001] The utility model relates to the technical field of Lentinula edodes strains, and specifically relates to a fermentation tank for cultivating Lentinula edodes strains. Background Technique

[0002] Lentinula edodes belongs to Basidiomycetes, Agaricales, Tricholomataceae, and Lentinula. It originated in China, is the second largest mushroom in the world, and is also a well-known precious edible mushroom in China. Lentinula edodes strains usually refer to the propagation materials composed of Lentinula edodes mycelium and its growth substrate, and are divided into three levels: mother strain, original strain, and production strain. The mother strain is the source, and most of them need to be isolated, screened, improved, and cultured from Lentinula edodes spores. Lentinula edodes strains, originally referring to spores (equivalent to the seeds of plants), now more broadly refer to Lentinula edodes mycelium and its growth substrate. These strains play a crucial role in edible mushroom cultivation and directly affect the yield and quality of Lentinula edodes.

When the pH value of the fermentation broth is higher than the set value, the ACID pump 422 is started, and an appropriate amount of acid (such as hydrochloric acid) is added to the fermentation medium 313 through the first infusion pipe 423 to reduce the pH value to the set range. On the contrary, when the pH value of the fermentation broth is lower than the set value, the BASE pump 426 is started, and an appropriate amount of alkali (such as sodium hydroxide) is added to the fermentation medium 313 through the second infusion pipe 424 to increase the pH value to the set range.
