Example Embodiment

[0011] The characteristics of the present invention can be illustrated by the following structural diagrams and examples.

[0012] figure 1 Shows that in this example ( figure 1 ) Sectional view of multifunctional biosolid fermentation tank.

[0013] The steps of the embodiment are: the fermentation raw materials are fed into the solid fermentor by mechanical or manual feeding from the feed port 9, the feeding amount is about 50% of the total volume of the tank, and appropriate moisture is added; starting the main speed regulating motor and the auger motor under the tank bottom , The horizontal propeller blade 23 and the screw auger 2 move and stir in the opposite direction to stir the material in the tank to make the material uniform; close the feeding port 9, and pass through the steam main pipe 15 and the steam branch pipe 14 under the auger under the tank bottom to 120 -125℃ steam sterilizes the material at high temperature; the jacket is cooled by cooling water 24, 25 and co...

Abstract

The invention relates to a multifunctional biological solid fermentation tank. The main body structure of the fermentation tank is a horizontal propeller, and spiral auger propeller blades are installed below the tank bottom. An auger is directly communicated with steam for sterilizing form the bottom of the tank and communicated with air for cooling, a spray tube on the upper part of the tank body sprays bacterial liquid for inoculation and can also spray water mist for humidity regulation, and thus, uniform inoculation and humidity control can be realized. The unique tank body horizontal type propeller and the auger coordination system below the tank body are utilized, and the circular flowing and the thorough mixing of a solid material in the tank body during fermentation are realized by controlling the rotating speed and the rotating direction; stirring nonuniformity caused by using a motor to rotate forwards or backwards repeatedly is avoided, automatic material discharge can be realized after fermentation, and material discharge is clean and complete. The operations of sterilization, cooling, inoculation, fermentation, temperature control, humidity control, ventilation, vacuum drying and the like required by solid fermentation can all be completed in the biological solid fermentation tank. The biological solid fermentation tank has the advantages of hardly no bacterial contamination, small occupied space, high automation degree, labor saving, investment saving and the like.

Description

Technical field [0001] The invention relates to the field of bio-fermentation mechanical processing and manufacturing, and relates to a bio-solid fermenter, in particular to a multi-functional bio-solid fermenter. Background technique [0002] Solid fermentation originated in China and has a long history of thousands of years. Solid fermentation can be used to produce many products such as biological feed, biological fertilizer, biological pesticide, enzyme preparation, organic acid, functional food, etc. It has the advantages of high production efficiency, low equipment investment, and no pollution to the environment. Solid fermentation is composed of water-insoluble solids, a small amount of water and air. During the fermentation process, the heat generated by microorganisms leads to water evaporation, which makes the fermentation system have a three-phase inhomogeneous vapor-liquid-solid, with serious concentration gradients and difficulties in heat and mass transfer. It...
