Description

Technical Field

[0001] The invention relates to the technical field of bio-enzyme catalysis production, in particular to a bio-enzyme catalysis reactor. Background Art

[0002] Bioenzyme catalytic reactor is a device that uses bioenzymes as catalysts for chemical conversion. It can achieve efficient, specific and environmentally friendly biocatalytic processes under low temperature and low pressure conditions. There are many types and structures of bioenzyme catalytic reactors, the most common of which are stirred tank type, fixed bed type, fluidized bed type, membrane type, etc. The design and operation of bioenzyme catalytic reactors need to consider factors such as enzyme activity, stability, recycling, mass transfer and heat transfer, flow state, and microbial contamination. Bioenzyme catalytic reactors have broad application prospects in the fields of food, medicine, energy, and environmental protection. Immobilized enzyme catalyst particles are a biocatalyst that combines enzymes with solid carriers. They can improve the stability, reusability and selectivity of enzymes and reduce the cost and loss of enzymes.

[0003] The bio-enzyme catalytic reactor is a traditional reactor with a stirring device. It can be divided into three types according to its operation mode: batch type, fed-batch type and continuous type. It is mainly composed of two parts: a stirrer and a heat preservation device. It has the advantages of simple structure, sufficient and uniform mixing of enzyme and substrate, easy control of temperature and pH, ability to handle colloidal substrates and insoluble substrates, and convenient catalyst replacement. It is often used in beverage and food processing industries.

[0004] The blade angle of the mixer mainly refers to the acute angle between the mixing blade and the mixing shaft, which will greatly affect the actual circumferential and axial movement speed of the mixture. If the blade angle of the mixer is 0 degrees, then the blade and the mixing shaft are in a parallel state, and the mixture moves in a circular motion with the mixing shaft as the center under the push of the blade. At this time, there is no axial force component, and no axial movement occurs, which means that the mixing time is constantly extended and the mixing uniformity cannot be effectively improved; when the blade angle of the mixer increases from 0 degrees to 90 degrees, within a certain angle range, the axial speed of the mixture will increase significantly, but if the angle of the mixer blade exceeds a certain range, the axial speed of the mixture will continue to decrease, and at the same time, the speed of the mixture's circular motion will also change significantly, making it continue to decrease. From an overall perspective, the stirring quality level will be seriously reduced; and the agitator of the existing bio-enzyme catalytic reactor does not have the function of adjusting the angle of the stirring blade, so that the axial speed of the raw materials of the bio-enzyme catalyst cannot reach the fastest value, thereby affecting the uniformity of the raw materials of the bio-enzyme catalyst after mixing.
