Embodiment 1

[0042] Embodiment 1: produce B.t biological pesticide wettable powder with the solid-state fermentation device shown in Fig. 1 and the method solid-state fermentation of the present invention:

[0043] As can be seen from Fig. 1, the gas-phase dual-dynamic solid-state fermentation device of the present invention comprises a horizontal cylindrical tank body 1, the tank front end of the tank body 1 is provided with a quick-opening structure 6 that can quickly open and close the tank door, and the tank body 1 The two ends of the upper tank wall are respectively equipped with air intake pipes controlled by the air intake valve 10, and the two ends of the lower tank wall of the tank body 1 are respectively equipped with exhaust pipes controlled by the exhaust valve 11. It is characterized in that: the tank body 1 is provided with A rectangular cuboid spacer with a square cross-section consisting of four partitions 41 placed in the axial direction, a cooling row pipe 81 placed parall...

Embodiment 3

[0057] Embodiment 3: Carry out the solid-state fermentation of "beauveria bassiana biopesticide production" with the same method and steps as in embodiment 1:

[0058]Beauveria bassiana is a kind of entomogenous fungus with a wide range of hosts and strong pathogenicity. It is non-toxic to human, animal, forest and tree crops, does not harm natural enemies, and does not pollute the environment. It is one of the most widely used microbial insecticides . Beauveria bassiana is a fungal pathogen of insects, which enters the body of insects through their epidermis or stomata, causing them to become sick and die. It has good insecticidal effect on leaf-eating pests, especially on forest pests. Market prospects. At present, my country is the largest country in the production and application of Beauveria bassiana insecticides, with an annual application area of ​​about 500,000 hectares, making important contributions to the control of pine caterpillars and corn borers. In foreign c...

Abstract

The present invention relates to a gas-phase double-dynamic solid fermentation techinque, and is characterized by that the solid material to be fermented is placed into a double-dynamic environment with pressure pulsatino and circular flowing air to make solid fermentation. Its fermentation equipment includes a horizontal cylindrical tank with a quickly-opening door, in the interior of the tank arectangular spacing cylinder which is formed from four partition boards and whose section is quadratic is axially placed, and in the space of partition board and tank wall a cooling calandria parallel to the partition board is arranged, and the vertical centre of the spacing cylinder is equipped with horizontally-arranged several groups of cooling calandria.

Description

technical field [0001] The invention belongs to the technical field of fermentation industry, and in particular relates to a gas-phase double-dynamic solid-state fermentation technology and a fermentation device thereof. technical background [0002] Since the cooperation of microbiologists and chemical engineers in 1945, the penicillin discovered by Fleming was successfully promoted to industrial production, and the submerged fermentation technology has developed the entire modern fermentation industry. Solid-state fermentation has been neglected because of the lack of engineering solutions to many problems such as transportation, stirring, temperature, humidity, pH, and oxygen supply, and has not met the requirements of the modern fermentation industry. The key problem is that there is no mature solid-state fermenter that meets the requirements of the modern fermentation industry. This has become a worldwide problem. [0003] The strict require...
