Description

Technical Field

[0001] The invention relates to a device for the industrialization of traditional fermented products, belonging to equipment for fermented agricultural products, and more specifically to an integrated device for preparing walnut paste. Background Art

[0002] Sauce is one of the typical traditional condiments in China. Sauce appeared in the late Neolithic Age. Our ancestors observed and practiced, followed the laws of nature, and added a lot of salt when preserving food. After unconscious pickling and fermentation, the food became sauce food. Zheng Xuan, a scholar in the Eastern Han Dynasty, wrote a note on the meat sauce in "Zhou Li": First dry the clean meat, then chop it, mix it with rice, koji and salt, add wine, put it in a bottle and seal it, and it will mature in 100 days. With the development of cultural exchanges between China and the West, unconscious fermentation will be replaced by industrialized explicit fermentation. Industrial fermentation is not only the determination of strains and industries, but also requires the development and research of industrial equipment suitable for fermentation of specific products.

[0003] The manufacturing and storage process of traditional fermented foods is complex, with a long production cycle and many influencing factors. There are three problems with the solid fermentation process of sauce products:

[0004] 1) Since solid fermentation requires equipment at different stages, the investment in solid fermentation equipment is huge and it occupies a large area of ​​the plant.

[0005] 2) High labor intensity for workers: Since the materials in the process are wet solids, the production equipment has not yet achieved a low degree of process automation, and the assembly line operation is inconvenient. It cannot be easily transported over long distances by pipelines like liquids, and is not easy to control automatically. A large amount of labor is required to carry it.

[0006] 3) Even if it is automated, too many fermentation tanks or tanks are transported back and forth, which is very detrimental to operational safety. The more wet solids are piled up in the workshop, the greater the risk of fire, and the higher the requirements for software and hardware management of fire prevention and other safety.

[0007] Therefore, how to provide a device that can realize the entire process from feeding, steaming, koji making and fermentation, thereby reducing the problems of large floor space and high labor consumption in the traditional fermentation process during the handling and storage of materials, is an urgent problem that technical personnel in this field need to solve.
