Abstract

The invention discloses a solid-state fermentation device and a fermentation method of the solid-state fermentation device. The solid-state fermentation device comprises a rectangle fermentation box (1) which is horizontally arranged, wherein a material inlet and outlet hole (3) with a closed door (2) is formed at one end part of the fermentation box (1), an air inlet pipeline (4) and a liquid flow pipeline (5) with a nozzle (14) are arranged at two sides of the material inlet and outlet hole (3) and are communicated with the fermentation box (1), an air outlet pipeline (6) is arranged at the other end part of the fermentation box (1), at least one layer of material pore plates (7) is horizontally arranged in the fermentation box (1), a vibrating motor (8) and a supporting frame (9) are arranged at the bottom of outside of the fermentation box (1), and the supporting frame (9) is movably connected with the middle part of the bottom of the outside of the fermentation box (1). The solid-state fermentation device can effectively carry out mass and heat transfer, reduce the shear force among the materials during usage, avoid the harm to hypha or thallus, prevent the pollution to the material and increase the quality of products.

Description

technical field [0001] The invention relates to the field of fermentation industry, in particular to a solid-state fermentation device and a fermentation method thereof. Background technique [0002] Solid-state fermentation is a biological reaction process carried out on a solid substrate that does not contain or only contains a small amount of free water. It has a large output per unit volume, high product concentration, and a wide range of applications, involving antibiotics, enzyme preparations, organic acids, food additives, biological Pesticide and biological fertilizer, feed and other industries. Modern solid-state fermentation urgently requires large-scale production of pure strains, and a lot of progress has been made in related research and application. However, the lack of solid-state fermentation equipment suitable for large-scale cultivation of pure strains severely restricts the application of solid-state fermentation. [0003] The key to the solid-sta...
