Solid-state fermentation device with uniform material distribution function and fermentation method

Abstract

The invention discloses a solid-state fermentation device with a uniform material distribution function and a fermentation method. The solid-state fermentation device is divided into a working bin, a fermentation bin and a quantitative discharging bin with clear functions, and a standard fermentation system is constructed. Everyday quantitative discharging of the quantitative discharging bin is controlled, a working frame is arranged in the working bin, stirring devices and material distribution devices are uniformly arranged on the working frame, quantitative and uniform material distribution in the fermentation bin is realized, and materials in the fermentation bin are subjected to layered fermentation. The combination property of the parts is good, equipment maintenance, fermentation production and standard operation of a fermentation process are guaranteed with adoption of standard equipment, the automation degree is high, multiple groups of equipment can be combined for working without excessive increase of operators, the management expense and production cost are lower, batch production and batch operation are facilitated, and operation and control are easy, so that standardization of fermented products as well as storage and transport operation of the products is guaranteed.

Description

technical field [0001] The invention relates to the technical field of fermentation, more specifically, to a solid-state fermentation device and system for uniform distribution of materials and a fermentation method. Background technique [0002] Solid-state fermentation refers to any fermentation process in which natural substrates are used as carbon sources and energy sources, or inert substrates are used as solid supports, and the system is anhydrous or close to anhydrous. The growth and products of microorganisms are all on the surface of the substrate. [0003] Solid-state fermentation is an effective means to solve the "three major" crises that human beings are currently facing. At present, many industrial and agricultural residues and urban domestic garbage have become social public hazards, which have adverse effects on the living environment of human beings. The fermentation process can be widely used in the treatment of degradable biological waste in domestic wast...

Problems solved by technology

[0004] Traditional fermentation (open air) often takes 1 to 3 months to reach maturity, and the surrounding area is foul-smelling, mosquitoes and flies breed in large numbers, and environmental pollution is very serious

Existing fermentation usually adopts tank-type fermentation, using a compost turning machine to turn the compost to stir, disperse, and evaporate water to continue fermentation, but this form of fermentation is easy to pollute the environment; while other sealed tank-type fermentation or Box-type fermentation uses a fixed stirring shaft or ventilation on the bottom of the box. The entire fermentation tank / box is a whole machine. After adjusting the parameters of the fermentation tank, put the fermentation materials into the fermentation tank / box at one time and start Ferment until the fermentation is completed and the material is discharged. The entire fermentation tank / box is fermented for the same time and the same degree of material, and the material is uniformly fed and discharged. The scale of the fermentation tank ultimately determines the scale of fermentation production. Manufacturers need a large number of warehouses to stack fermentation Good finished products require a lot of labor or machinery to load and unload finished products into or out of the warehouse, which brings huge labor and environmental pollution problems. The fermentation equipment occupies a large area and the labor intensity of fermentation production is high, so standardized production cannot be realized.

[0005] In addition, although the existing fermentation technology has gradually realized from open fermentation to closed fermentation, the feeding and discharging cannot be carried out in a closed state, and the problem of environmental pollution cannot be fundamentally solved; the existing fermentation technology Although the research from empirical fermentation to controlled fermentation is gradually carried out, the focus of the research is on the control of factors such as water, inoculation, and gas supply under the original fermentation production process mode, and there is a lack of fundamental processes such as standardized control of fermentation production. research on improvement
