Description

Technical Field

[0001] This application relates to the field of tofu processing technology, and in particular to an automatic tofu cutting device. Background Technology

[0002] The fermentation of tofu blocks through inoculation with microorganisms in stages promotes the metabolic activities of microorganisms, which in turn promotes the formation of the flavor and texture of fermented tofu. In the later stages of fermentation, the fermented tofu blocks need to be placed in a jar and sealed or sealed with oil to isolate the air and create an anaerobic environment, which is conducive to the growth of anaerobic microorganisms such as lactic acid bacteria. Further fermentation produces a unique flavor, thus producing fermented tofu, also known as bean curd.

[0003] In the current process, fermentation bacteria need to be evenly inoculated on the surface of the tofu blocks before fermentation and pickling. However, the current process involves manually pouring fermentation bacteria liquid onto the tofu blocks, which results in waste of the fermentation liquid and makes it difficult to recycle.

[0004] The information disclosed in the background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.
