Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of functional sugars and enzyme engineering, and particularly relates to a production device for immobilized enzyme particles of 3-epimerase for D-allulose production. Background Art
[0002] Allulose is a natural hexulose that is relatively rare in nature and is a functional rare sugar. Its sweetness and taste are similar to or close to those of sucrose, but its calories are much lower than those of sucrose. In addition to being a sucrose substitute, allulose has unique physiological function characteristics, and its potential health care value has been gradually explored. D-allulose 3-epimerase (D-psicose 3-epimerase, abbreviated as DPE) is the isomerase with the highest epimerization reaction activity in the ketose 3-epimerase family that synthesizes D-allulose using D-fructose as a substrate. Therefore, DPE is the key enzyme used in the current industrial production of D-allulose.
[0003] The production of D-allulose using D-allulose-3-epimerase often involves multiple steps. These complex processing technologies and techniques result in high production costs and low efficiency for D-allulose production. Compared with the single addition of liquid enzyme, the advantage of the immobilized enzyme reaction is to avoid multi-step operations and time-consuming traditional production processes. The immobilized enzyme also has the characteristics of anti-environmental interference, better stability, and more feasible industrial production compared with the traditional liquid enzyme. However, there is currently no dedicated production device for immobilized enzyme particles related to D-allulose-3-epimerase. Therefore, in order to improve the production efficiency of preparing DPE enzyme immobilized enzyme particles, simplify the production process, and reduce the production cost, it is necessary to design and manufacture related process devices. Summary of the Invention
[0004] The technical problem to be solved by the utility model is to provide an immobilized enzyme particle production device, which overcomes the defects of low efficiency and high production cost in the preparation of enzyme immobilized enzyme particles in the prior art, simplifies the production process of allulose isomerase immobilized enzyme particles, reduces the production cost of the immobilized enzyme, and has the prospect of industrial application.

[0018] The present utility model will be further described below in conjunction with the drawings and embodiments.
[0019] Embodiment 1:
[0020] As Figure 1 and Figure 2As shown in the figure, an immobilized enzyme particle production device includes a cylindrical material container 1 with an open top. The lower part of the material container 1 is a sieve 11, and a stirring motor 2 is provided in the center of the upper part. An S-shaped granulating knife plate 3 is fixedly connected to the stirring shaft (not marked) below the stirring motor 2. A funnel 4 is provided below the material container 1, and the discharge port of the funnel 4 is located above the feed port of the dryer 5. A driving motor 51 and a high-temperature blower 52 are provided at the feed port end of the dryer 5. A sandwich layer 53 is provided on the side wall of the dryer 5, and an electric heating wire (not marked) is provided in the sandwich layer 53. A number of flow guiding baffles 54 are evenly and alternately arranged on the inner wall of the dryer 5.
[0021] Above the discharge port end of the dryer 5, a dust suction hood 6 is provided. The dust suction hood 6 is connected to a gas-dust separation device (not marked) through a pipeline. Below the discharge port end of the dryer 5, a particle collection tank 7 is provided.
[0022] During actual production, the pretreated material is poured into the material container 1. The S-shaped granulating knife plate 3 is driven by the stirring motor 2 to extrude the material, so that the material passes through the sieve 11 to form particles with appropriate pore diameters, and then falls into the funnel 4 and continues to slide into the dryer 5 below the funnel 4 to remove moisture. The dryer 5 is driven by the driving motor 51 to rotate the cylinder of the dryer 5, and high-temperature air is blown in by the high-temperature blower 52 for heating and blowing the material. At the same time, the electric heating wire in the sandwich layer 53 is used to heat the material, and the rotation of the flow guiding baffle 54 makes the immobilized enzyme particles roll forward. The above settings enable the particles to be continuously heated and dried during the turning process. The water vapor and some dust evaporated during the heating process are discharged from the discharge port along with the hot air blown by the high-temperature blower 52, and are collected by the dust suction hood 6 for gas-dust separation, and then the collected dust is reused. The finished immobilized enzyme particles after heating and drying are finally discharged through the discharge port of the dryer 5.
