Description

Technical Field

[0001] The invention belongs to the technical field of xylanase catalytic reaction equipment, and in particular relates to a xylanase catalytic reaction device with good thermal stability. Background Art

[0002] Xylan is a heterogeneous polysaccharide present in plant cell walls and is the main component of plant hemicellulose. Most xylans are complex, highly branched heterogeneous polysaccharides containing many different substituents. Therefore, the biodegradation of xylan requires a complex enzyme system to degrade xylan through the synergistic effects of various components.

[0003] Xylanase is a biocatalyst, mainly derived from microorganisms such as bacteria and fungi. It can decompose xylan in plant cell walls and improve the texture and taste of food, so it is widely used in the food industry. Xylanase is safe for the human body under normal conditions of use because it will be decomposed in the digestive system and will not directly enter the blood circulation; during the catalytic reaction of xylanase and xylan, it is necessary to fully stir and mix them through a stirring device to increase the catalytic reaction rate and improve the production efficiency of the product.

[0004] However, when the existing xylanase catalytic reaction device is in use, the xylan and the xylanase are stirred and mixed by a simple stirring paddle, which makes the xylan and the xylanase solution have low fluidity in the reaction barrel, causing the xylan and the xylanase to only move in a circular motion under the action of the stirring paddle, resulting in poor stirring effect of the stirring paddle on the xylan and the xylanase, resulting in low uniformity of the mixing of the xylan and the xylanase, which affects the xylanase catalytic reaction. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a xylanase catalytic reaction device with good thermal stability, which can effectively improve the fluidity and stirring effect of xylan and xylanase in a reaction barrel.

[0015] Furthermore, the rotating plate is evenly distributed with a plurality of blades along the circumference, and the rotating plate is also evenly distributed with through holes arranged between adjacent blades.

[0016] Compared with the prior art, the present invention has the following beneficial effects: When the present invention is in use, the rotating plate cooperates with the side stirring paddle, and the lower stirring paddle cooperates with the material-diverting plate. While mixing and stirring xylan and xylanase, the rotating plate and the material-diverting plate promote the flow of xylan and xylanase in the reaction barrel, so as to improve the uniformity of the mixing of xylan and xylanase.
