DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will describe the specific implementation manners of this embodiment with reference to the attached Figures 1-3 , explaining the specific implementation manners of this embodiment.

[0028] Carotenoids include one or more of lutein, zeaxanthin, astaxanthin, lycopene, carotene, β-carotene, fucoxanthin, cryptoxanthin, 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 to this application.

[0029] The embodiment of this application provides a mixing device for producing carotenoid microcapsules. Refer to Figures 1-3, a carotenoid microcapsule production mixing device, including an emulsification tank 1, a drying tower 2 and an ultrasonic assisted stirring device, wherein the drying tower 2 and the emulsification tank 1 are fixedly connected by a first support frame 18, the drying tower 2 is located below the emulsification tank 1, and the drying tower 2 is fixed to the ground by a second support frame 26. The emulsification tank 1 includes a stirring motor 4 fixed above the tank body, the output shaft of the stirring motor 4 is connected to one end of a stirring rod 5, the stirring rod 5 is located inside the tank body, and the stirring rod 5 is also provided with a first stirring blade 6. In this embodiment, the number of the first stirring blade 6 can be set according to specific circumstances. In addition, the stirring rod 5 is also connected to a stirring frame 8, the stirring frame 8 is rectangular, and scrapers 9 are fixed on both sides of the stirring frame 8; the outer side of the scraper 9 is in contact with the inner wall of the emulsification tank 1, and the scraper 9 is used to scrape the inner wall, which can prevent the raw materials for preparing lutein, lutein ester or astaxanthin, astaxanthin ester from sticking to the inner wall of the emulsification tank during the reaction, and can also use the scraper 9 to mix the above-mentioned raw materials more evenly. In addition, after the preparation is completed, the scraper 9 can be used to quickly and effectively clean the inner wall of the emulsification tank 1. One end of the stirring rod 5 is arranged through the stirring frame 8, and a second stirring blade 7 is also arranged on the end of the stirring rod 5 passing through the stirring frame 8; the second stirring blade 7 is located close to the bottom of the emulsification tank 1, and the volume of the second stirring blade 7 is slightly smaller than the first stirring blade 6, but the thickness of the second stirring blade 7 is wider, which is convenient for fully mixing the preparation materials of lutein or astaxanthin deposited at the bottom.

[0030] A feed port 3 is also provided above the emulsification tank 1. The feed port 3 is funnel-shaped, which is convenient for quickly adding lutein, lutein esters or astaxanthin, astaxanthin ester preparation raw materials during the preparation process. Since a certain temperature is required during the preparation process, a heating device 10 is also fixed on the inner wall above the emulsification tank 1 to adjust the temperature inside the emulsification tank 1.

[0031] In this embodiment, an ultrasonic auxiliary stirring device is also provided. Since ultrasonic waves have mechanical effects and cavitation effects, during the preparation process, the use of ultrasonic auxiliary stirring devices can effectively promote the mixing of the raw materials to be prepared more fully, promote liquid emulsification, and thus improve the utilization rate and emulsification effect of the raw materials, greatly improving the production efficiency. After the preparation is completed, the ultrasonic waves generated by the ultrasonic auxiliary stirring device can also be used to quickly and efficiently clean the inside of the emulsification tank 1, effectively avoiding contamination such as residual liquid and bacterial growth. The ultrasonic auxiliary stirring device includes an ultrasonic generator 13, a transducer 11 and a horn 12; wherein the horn 12 is connected to the transducer 11 and is embedded on both sides of the inner wall of the emulsification tank 1, and establishes a communication connection with the ultrasonic generator 13, and the ultrasonic generator 13 is used to control the generation time and frequency of the ultrasonic wave, and control the transducer 11 and the horn 12 to emit ultrasonic waves of a specific frequency. The above-mentioned ultrasonic wave generation process belongs to the existing technical means, and will not be described in detail here.

[0032] In order to monitor the preparation process in real time, a temperature sensor 14 and a pressure sensor 15 are also provided on the inner wall of the emulsifying tank 1, which are used to observe the temperature and pressure parameters in the emulsifying tank 1 in real time, and upload the above data to the terminal. If the monitored temperature and pressure values exceed the appropriate range, an alarm will be automatically issued for reminder. A drain pipe 16 is provided below the inner wall on one side of the emulsifying tank 1, and an exhaust pipe 17 is provided above the inner wall on the other side. Solenoid valves for controlling the on-off of the pipeline are provided on both the drain pipe 16 and the exhaust pipe 17. When the terminal issues an alarm, the air pressure inside the emulsifying tank 1 can be adjusted by opening the solenoid valves located on the drain pipe 16 and the exhaust pipe 17.

[0033] When the preparation raw materials are fully mixed and emulsified, they flow into the drying tower 2 through the liquid outlet of the emulsifying tank 1 for spray granulation. In this embodiment, an atomizer 19 is installed in the liquid outlet of the emulsifying tank 1, and the atomizing port 20 of the atomizer 19 is located at the top of the drying tower 2, and the positions of the atomizer 19 and the atomizing port 20 correspond to each other. In order to further improve the effect of spray granulation, the atomizer 19 in the liquid outlet of the emulsifying tank 1 is also communicated with a ventilation duct 21, and an air heater 22 is provided in the ventilation duct 21, which can heat the air sent by the air blower 23, so that the high-temperature and high-pressure air enters the atomizer 19. This can not only maintain the temperature of the emulsion, but also use the heated air to quickly form microcapsule particles, significantly improving the embedding rate and production efficiency. After the preparation liquid is atomized and dried to form microcapsule particles, they enter the drying tower 2, are quickly cooled and fixed in shape in the drying tower 2, and finally are collected in the collection box through the discharge port 24 below the drying tower 2. A valve 25 for controlling the on-off of the discharge port is provided on the discharge port, and a new collection box can be replaced at any time after the collection box is full.

[0034] The working principle of a carotenoid microcapsule production mixing device provided in this embodiment is as follows:

[0035] First, start the switches of the stirring motor 4, the heating device 10 and the ultrasonic assisted stirring device. Add the preparation raw materials of lutein, lutein ester or astaxanthin, astaxanthin ester into the emulsifying tank 1 through the feed port 3. Drive the first stirring blade 6, the second stirring blade 7, the stirring frame 8 and the scraper 9 to rotate through the stirring motor 4, and cooperate with the ultrasonic waves generated by the ultrasonic assisted stirring device to fully mix and emulsify the preparation raw materials. The fully mixed and emulsified liquid flows through the atomizer 19 for spray granulation. During the spray granulation process, the air blown by the air blower 23 is heated by the air heater 22 and then introduced into the atomizer 19 to spray granulate the fully mixed and emulsified liquid to form microcapsule particles. The microcapsule particles are quickly cooled and fixed in shape in the drying tower 2, and finally are collected in the collection box through the discharge port 24 below the drying tower 2.

[0036] After preparation, cleaning liquid is added through the feed inlet 3. By the mutual cooperation of the first stirring blade 6, the second stirring blade 7, the scraper 9 and ultrasonic waves, the material residues in the device are quickly cleaned through stirring and ultrasonic assistance, avoiding the pollution of materials in the next use, realizing the rapid and efficient cleaning of the emulsifying tank 1, avoiding pollution such as liquid residue and bacterial growth, and improving production efficiency.
