Description

Technical Field

[0001] The utility model relates to the technical field of fermentation equipment, in particular to solid-state fermentation equipment. Background Art

[0002] Solid-state fermentation is a fermentation process carried out in the absence of a liquid aqueous phase. Microorganisms usually grow and metabolize in solid substrates. This fermentation method is widely used in food processing, feed production, biotechnology and other fields. Solid-state fermentation equipment is mainly used as a container for solid materials to carry out biological reactions with one or more microorganisms in the absence of almost no free water.

[0003] Since solid-state fermentation requires temperature control, most existing solid-state fermentation equipment heats by setting a heating element in the equipment, and this heating method is uneven, so that the temperature of the solid material in different places in the equipment is different, thus affecting the fermentation effect. Therefore, the utility model provides a solid-state fermentation equipment to solve the problems raised in the above background technology. Utility Model Content
