Problems solved by technology

The above-mentioned solid-state fermentation tanks are unevenly mixed, easy to form agglomerates, and difficult to dissipate heat. Although some tanks are designed to replenish water or introduce air in the early stage, it leads to uneven growth, low growth efficiency, and easy pollution

Embodiment 1

[0026] Take wheat bran and water according to the ratio of 1:0.5, add them into the feeding port, start stirring the mixed materials to form loose materials.

[0027] The jacket is fed with steam sterilized materials, and when the temperature reaches 95°C, the stirring is stopped, and the sterilization is continued through direct steam into the tank, and the temperature is kept at 121°C for 45 minutes.

[0028] Pass in sterile air to cool down, and pass in jacket water to cool down. When the temperature in the tank drops to 100°C, start stirring to quickly mix and dissipate heat.

[0029] When the temperature of the material reaches 34°C, the seeds can be added to the sterilized medium through the inoculation port, and the seed liquid can be mixed by reverse stirring.

[0030] Due to the moisturizing effect of the solid fermentation tank, moist air is introduced through the bottom, and evenly dispersed into the medium through the filter mesh bottom plate at the bottom to accel...

Abstract

The invention provides a differential double-spiral stirring type integrated solid fermenting device. The differential double-spiral stirring type integrated solid fermenting device comprises a cylinder body, wherein a double-spiral agitator blade is arranged in the cylinder body; a 40 to 100-mesh filtering screen hole bottom plate is arranged at the bottom part of the cylinder body; the side wallof the lower part of the cylinder body is provided with a slag outlet. The differential double-spiral stirring type integrated solid fermenting device has the advantages that by arranging the 40 to 100-mesh filtering screen hole bottom plate at the bottom part of the cylinder body, the integration effect of solid enzyme water dissolving and extracting is realized, the sealed type operation is performed at the whole surface, and the easiness in pollution is avoided; by adopting the double-spiral agitator blade, a large spiral stirring blade and a small spiral stirring blade are staggered with90 degrees, the looseness degree of solid koji is improved by positive and reverse stirring, and the extending and heat radiating effects of hyphae are accelerated; by arranging the slag outlet to discharge slag, the filtering, slag discharging and maintenance can be conveniently performed.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation equipment manufacturing, and in particular relates to a differential double-helix stirring integrated solid fermentation device. Background technique [0002] Solid-state fermentation is a traditional fermentation process, using inert carrier as a support, the water content of the formed medium is between 30-70%, without too much free water, suitable for the production of fungal microorganisms that grow in a low-humidity state metabolite. Solid-state fermentation is fermented in a dense medium environment, which is prone to generate a large amount of fermentation heat. The spread of mycelium leads to agglomeration of the medium, viscosity, and difficulty in air transmission, which easily leads to an anaerobic state inside the medium and is not easy to grow. The removal of its metabolic heat often poses problems, especially when produced in large quantities, often limiting its larg...
