DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-3 , describing the specific implementation of this embodiment.

[0027] Carotenoids include one or more of lutein, zeaxanthin, astaxanthin, lycopene, carotene, β-carotene, fucoxanthin, cryptoxanthin, and capsanthin. In this embodiment, the preparation of lutein, lutein esters, astaxanthin, and astaxanthin esters is taken as an example, and other types of carotenoids can also be prepared, which does not constitute a limitation of the present application.

[0028] The present invention provides a microwave-assisted device for preparing carotenoid microcapsule preparations. Figure 1 , a device for preparing carotenoid microcapsule preparation with microwave assistance, comprising an emulsification tank 1, a microwave cover 2 and a forming tower 3;

[0029] The emulsification tank 1 includes a feed bin 7, a stirring device and a heating device 8. The feed bin 7 is located at the top left side of the emulsification tank 1. The raw materials for preparing lutein, lutein ester or astaxanthin, astaxanthin ester can be quickly added into the emulsification tank 1 through the feed bin 7. The stirring device includes a driving motor 9, a rotating shaft 10, a stirring frame 12 and a stirring blade 11, wherein the driving motor 9 is located at the top of the emulsification tank 1, and the driving motor 9 is connected to the stirring frame 12 through the rotating shaft 10, wherein the stirring frame 12 is rectangular, the rotating shaft 10 passes through the upper frame of the stirring frame 12 and is fixed to the lower frame of the stirring frame 12, and the stirring blade 11 is fixed on the rotating shaft 10, and the stirring blade 11 is arranged in parallel at equal intervals according to the set angle, and one or more pairs can be provided. The rotating shaft 10 is driven by the driving motor 9 to rotate, and then the stirring blade 11 and the stirring frame 12 are driven to rotate, which can ensure that the raw materials for preparing lutein, lutein ester or astaxanthin, astaxanthin ester are fully mixed; and in order to prevent the raw materials for preparing lutein or astaxanthin from sticking to the inner wall of the emulsification tank 1 during high-temperature stirring, scrapers 13 are also fixed on both sides of the stirring frame 12, and the inner wall of the emulsification tank 1 can be repeatedly scraped by the scraper 13 to prevent sticking, and also ensure that the raw materials are fully mixed. In the process of preparing carotenoid microcapsule preparation, suitable temperature helps to promote the reaction rate between the raw materials. Therefore, in this embodiment, a heating device 8 is fixed on the inner wall of the top of the emulsification tank, and the heating device 8 is used to increase the reaction temperature of the preparation process, thereby improving the reaction efficiency.

[0030] The outside of the emulsification tank 1 is also covered with a microwave cover 2, the bottom of the microwave cover 2 is fixed to the forming tower 3 through the second support frame 20, and the microwave cover 2 is also provided with an opening for accommodating the rotating shaft 10, the feed bin 7 and the heating pipe 21. The microwave cover 2 is a double-layer structure, and the double-layer structure is also filled with heat-insulating materials. Heat-insulating cotton can be selected as the heat-insulating material, which can effectively prevent the temperature loss during the reaction process. A microwave generator 6 is also provided on both sides of the inner wall of the microwave cover 2, one side of the microwave generator 6 is fixed to the microwave cover 2, and the other side is fixed to the outer wall of the emulsification tank 1; the microwave generator 6 cooperates with the heating device 8 inside the emulsification tank 1 to quickly increase the temperature inside the emulsification tank in a short time, thereby improving the emulsification efficiency of the prepared raw materials, which is conducive to the high-temperature emulsification process. At the same time, the use of microwaves also ensures that the reaction in the emulsification tank 1 is carried out in a sterile environment.

[0031] When the prepared raw materials react in the emulsification tank 1, due to the influence of high temperature, part of the solvent will evaporate, causing the internal pressure of the emulsification tank 1 to be too high, affecting the normal progress of the reaction and posing certain safety hazards. For this reason, a drain pipe 14 and an exhaust pipe 15 are respectively provided on the left and right sides of the bottom of the emulsification tank 1, and an electromagnetic valve is provided on the drain pipe 14 and the exhaust pipe 15 to control the closure of the pipeline. On the one hand, the gas in the emulsification tank 1 can be discharged to reduce the pressure in the emulsification tank 1; on the other hand, after use, the excess prepared raw materials can be discharged in time through the drain pipe 14 to keep the inside of the emulsification tank 1 clean. In addition, in order to achieve real-time monitoring of the temperature and pressure inside the emulsification tank 1, a first temperature detector 16 and a first pressure detector 17 are provided at the top of the left inner wall of the emulsification tank 1, and a second temperature detector 18 and a second pressure detector 19 are provided at the bottom of the right inner wall of the emulsification tank 1. By setting two pairs of temperature detectors and pressure detectors, the internal temperature and pressure of the emulsification tank 1 can be fully monitored to ensure the normal progress of the reaction.

[0032] The bottom of the emulsification tank 1 is also connected to the forming tower 3 through a heating pipe 21 to achieve the integrated preparation of carotenoids. The fully mixed and emulsified preparation raw materials in the emulsification tank 1 are transmitted to the forming tower 3 through the heating pipe 21, wherein the heating pipe 21 is heated by an internal heater 22 to effectively maintain the temperature of the preparation raw material emulsion. In addition, an atomizer 23 is provided at the outlet of the heating pipe 21, and an atomization port 24 is also provided at the top of the forming tower. The atomizer 23 corresponds to the position of the atomization port 24, and the preparation raw material emulsion is spray-dried by the atomizer 23. The forming tower 3 is funnel-shaped and fixed to the ground through a first support frame 27. A discharge port 4 is installed below the forming tower 3, and a silo car 5 is also provided directly below the discharge port 4. A solenoid valve is also provided on the discharge port 4 to control the opening and closing of the discharge port 5. In addition, an air inlet duct 25 is provided in the middle of the right side of the forming tower 3. The air is supplied by the blower 26 to blow off the residual carotenoid raw materials on the inner wall of the forming tower 3 and flow into the silo car 5 through the discharge port 4, thereby realizing the integration of raw material mixing, emulsification and microcapsule preparation, and further improving production efficiency.

[0033] The working principle of the device provided in this embodiment is as follows:

[0034] First, the driving motor 9, the heating device 8 and the microwave generator 6 are started, and various microcapsule preparation raw materials such as carotenoids enter the emulsification tank 1 through the feed bin 7. The driving motor 9 drives the stirring blade 11 to fully stir and mix the preparation raw materials. Under the combined action of the heating device 8 and the microwave generator 6, the microwave energy can improve the emulsification efficiency of the preparation raw materials in a relatively short time. At the same time, the scraper 13 on the stirring frame 12 reciprocates to scrape the inner wall of the emulsification tank 1 to prevent wall sticking, which is conducive to the full progress of the emulsification process. Then, the fully emulsified raw materials enter the top of the forming tower 3 through the heating pipe 21. The heating pipe 21 can effectively maintain the temperature of the raw material emulsion, and spray drying and granulation are performed through the atomizer 23 and the atomization port 24. The blower 26 installed on the middle air intake on the right side is used to supply air through the air intake pipe 25 to blow the residual carotenoid raw materials on the inner wall of the forming tower 3 and fall down, and merge into the silo car 5 through the discharge port 4, so as to realize the integration of raw material mixing, emulsification and microcapsule preparation.

[0035] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
