Problems solved by technology

The patent is a non-removable reactor, which is difficult to clean after a period of fermentation. At the same time, during the fermentation process with complex fermentation liquid components, the gas distribution plate is easily glued by the sugar solution, which blocks the plate holes and makes the gas distribution uneven; In addition, the feed pipe of this patent is directly inserted into the fermentation unit, so that the feed liquid entering the fermentation unit is mixed unevenly; in the overall design of the reactor, there is no detection device port and sampling port on each unit, which provides monitoring and detection for the fermentation process. caused certain difficulties

Embodiment Construction

[0022] Such as figure 1 As shown, the present invention includes: an air storage chamber 1, a three-section spindle-shaped fermentation body 2 and a mash storage chamber 3. Air storage chamber 1, three-stage spindle-shaped fermentation body 2, and mash storage chamber 3 are connected vertically from bottom to top; The gas passed into it redistributes and provides gas power for the fluidization of the fermentation broth throughout the reactor. The three-segment spindle fermenter 2 provides fermentation space for the fermentation reaction. The bottom of the mash storage chamber 3 and the top of the three-stage spindle-shaped fermentation body 2 can be bonded, welded or flanged as required. The mash storage chamber 3 has the fermentation liquid for storing and fermenting, and has the functions of separating the fermentation liquid and immobilizing yeast particles. Three-phase separation function with carbon dioxide gas.

Abstract

The three-stage fluid bed fixing barm alcohol fermentation bio-reactor comprises: a gas holder, a three-stage fusiformate fermentation body, and a storage chamber for fermented glutinour rice; all vertically connected in turn by flange. This invention is simple, needs low consumption and land area, and improves material utility.

Description

technical field [0001] The invention relates to a reactor in the technical field of bioengineering, in particular to a three-stage fluidized bed immobilized yeast alcohol fermentation bioreactor. Background technique [0002] Fermentation equipment is the core equipment in the production of fermentation industry. Fermentation is a process in which specific species of microorganisms absorb nutrients in materials in nutrients, and metabolize products through the growth of microorganisms and transform nutrient substrates. The process of producing alcohol by biological method is a typical microbial fermentation process to obtain usable metabolites. The fermentation reactor provides a good nutritional environment and growth and metabolism environment for the microorganisms in this production process. Liquid alcohol fermentation, changing the traditional alcohol fermentation method, can improve the pipeline, automation and continuous level of the fermentation process. At present...
