However, the existing reaction equipment cannot effectively make the catalyst and the reaction raw materials contact evenly, so it is necessary to install a sufficient mixing mechanism to improve the purity of the maltodextrin product.

[0005] Therefore, in view of the above problems, a catalytic synthesis of apple ester reaction equipment is proposed. Utility Model Content

[0016] Technical effects and advantages of the utility model:

[0017] 1. Compared with the prior art, the catalytic synthesis of apple ester reaction equipment is provided with a sufficient mixing mechanism, so that when the equipment is used later, the mixing uniformity of the raw material for catalytic synthesis of apple ester and the catalyst can be improved through the sufficient mixing mechanism, and the product purity can be improved. The raw material for catalytic synthesis of apple ester is introduced into the heating reaction tank through the feed port, and the apple ester reaction catalyst in the liquid storage tank is extracted by the pump body, and is transported to the rotating shaft through the infusion tube, so that it is discharged into the reactor through the discharge port inside each stirring rod to contact with the raw material for catalytic synthesis of apple ester. At the same time, the motor is turned on to drive the rotating shaft to rotate, so that the catalyst is fully in contact with the raw material during the discharge process, ensuring that the reactants are efficiently mixed and stirred in the heating reaction tank, which helps to accelerate the reaction rate of catalytic synthesis of apple ester and improve production efficiency. At the same time, a scraper is provided on the outside of the rotating shaft, and the scraper moves along the inner wall of the heating reaction tank while the rotating shaft rotates, thereby reducing the residual material on the inner wall, reducing the generation of by-products, and improving the purity of the apple ester product.

[0018] 2. Compared with the prior art, the catalytic synthesis of fructone reaction equipment cooperates with each other among the treatment box, the suction fan, the exhaust pipe, the condenser and the cooling water. Since some harmful gases or volatile organic compounds will be generated during the catalytic process of fructone, the gas is transported to the treatment box through the exhaust pipe by the suction fan to prevent the harmful gas from being discharged into the environment. By storing cooling water in the treatment box, the volatile organic compounds and other condensable components in the gas will be condensed into liquid on the surface of the condenser, thereby being separated from the gas, and the condensed liquid can be collected and properly treated to avoid pollution to the environment.

[0027] The raw material of the apple ester reaction is introduced into the heating reaction tank 3 through the feed port 4, and the apple ester reaction catalyst in the liquid storage tank 10 is extracted through the pump body 11, and is transported to the rotating shaft 6 through the infusion tube 12, so as to be discharged into the reactor 1 through the discharge port 13 inside each stirring rod 7 to contact with the apple ester raw material. At the same time, the motor 5 is turned on to drive the rotating shaft 6 to rotate, so that the catalyst is fully in contact with the raw material during the discharge process, ensuring that the reactants are efficiently mixed and stirred in the heating reaction tank 3, which helps to accelerate the reaction rate of the catalytic synthesis of apple ester and improve the production efficiency. At the same time, a scraper 9 is provided on the outside of the rotating shaft 6. When the rotating shaft 6 rotates, the scraper 9 moves along the inner wall of the heating reaction tank 3, reducing the residual material on the inner wall, reducing the generation of by-products, and improving the purity of the apple ester product.

[0028] Embodiment 2

[0029] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, as described below:

[0030] like Figure 1As shown, as a preferred embodiment; a suction fan 15 is nested on one side of the outside of the reactor 1, an exhaust pipe 16 is nested on one side of the suction fan 15, and a treatment box 14 is nested on the other side of the exhaust pipe 16. Furthermore, since some harmful gases or volatile organic compounds will be generated during the catalytic process of maltose, the gas is transported to the treatment box 14 through the exhaust pipe 16 by the suction fan 15 to prevent the harmful gas from being discharged into the environment, thereby reducing the impact on the environment and improving the working environment.

[0031] like Figure 4 As shown, as a preferred embodiment; a condenser 17 is embedded in the inner wall of the processing box 14, and cooling water 18 is embedded in the interior of the processing box 14. Furthermore, by storing the cooling water 18 in the processing box 14, the volatile organic compounds and other condensable components in the gas will condense into liquid on the surface of the condenser 17, thereby being separated from the gas, and the condensed liquid can be collected and properly disposed of to avoid pollution to the environment.

[0032] like Figure 1 As shown, as a preferred embodiment; an observation window 19 is nested on the outside of the reactor 1, and a movable door 20 is nested on the outside bottom of the reactor 1. Furthermore, the observation window 19 allows the operator to directly observe the internal situation of the reactor 1 from the outside. The operator can monitor the reaction process in real time to ensure that the reaction proceeds as expected and promptly discover any abnormal situation or problem. The design of the movable door 20 also provides flexibility, allowing the operator to operate as needed.

[0033] like Figure 3 As shown, as a preferred embodiment; a plurality of stirring rods 7 are provided, which are evenly distributed outside the rotating shaft 6. Further, the plurality of stirring rods 7 are used to improve the contact and mixing effect of the apple ester raw material and the catalyst.

[0034] like Figure 3 As shown, as a preferred embodiment; the cross-sectional shape of the scraper 9 is arc-shaped. Furthermore, the design of the scraper 9 not only helps to mix the materials, but also helps to clean the inner wall of the heating reaction tank 3 after the reaction is completed, reduces material residue, and helps to reduce cleaning workload and maintenance costs.

[0035] like Figure 3 As shown, as a preferred embodiment; a plurality of discharge ports 13 are provided, which are evenly distributed inside the corresponding stirring rod 7. Furthermore, the even distribution of the plurality of discharge ports 13 ensures that during the stirring and reaction process, the liquid can be discharged from multiple points at the same time, thereby achieving more uniform discharge and improving the reaction efficiency.

[0036] like Figure 1As shown, as a preferred embodiment; the suction fan 15 is used in conjunction with the exhaust pipe 16, and further, the gas is guided from the exhaust pipe 16 to the processing box 14 through the suction fan 15.

[0037] The working process of the utility model is as follows:

[0038] When the catalytic synthesis of apple ester reaction equipment is used later, first, the apple ester reaction raw material is introduced into the heating reaction tank 3 through the feed port 4, and the apple ester reaction catalyst in the liquid storage tank 10 is extracted through the pump body 11, and is transported to the rotating shaft 6 through the infusion tube 12, so that it is discharged into the reactor 1 through the discharge port 13 inside each stirring rod 7 to contact with the apple ester raw material. At the same time, the motor 5 is turned on to drive the rotating shaft 6 to rotate, so that the catalyst is fully in contact with the raw material during the discharge process, ensuring that the reactants are efficiently mixed and stirred in the heating reaction tank 3, which helps to accelerate the reaction rate of the catalytic synthesis of apple ester and improve the production efficiency. At the same time, a scraper 9 is provided on the outside of the rotating shaft 6, and the rotating shaft 6 rotates. At the same time, the scraper 9 moves along the inner wall of the heating reaction tank 3 to reduce the residual material on the inner wall, reduce the generation of by-products, and improve the purity of the apple ester product. Since some harmful gases or volatile organic compounds are generated during the catalytic process of apple ester, the gas is transported to the treatment box 14 through the exhaust pipe 16 by the suction fan 15 to prevent the harmful gas from being discharged into the environment. By storing cooling water 18 in the treatment box 14, the volatile organic compounds and other condensable components in the gas will be condensed into liquid on the surface of the condenser 17, thereby being separated from the gas, and the condensed liquid can be collected and properly treated to avoid pollution to the environment. This is the working process and working principle of the device.
