At the same time, the jet pipe 21 rotates with the spray pipe 17, and then the dry ice particles pass through the delivery pipe 19 and the air inlet pipe 20 in sequence, so that the multiple sets of second nozzles 22 spray the dry ice particles out. , the atomized fish oil calcium alginate microcapsule liquid sprayed by the multiple groups of first nozzles 18 is quickly cooled down to sublime the water in the fish oil calcium alginate microcapsule liquid, thereby drying the fish oil calcium alginate microcapsules. At the same time, the fish oil calcium alginate microcapsules are hit by dry ice particles to reduce the adhesion of the fish oil calcium alginate microcapsules. Part of the dry ice particles are sprayed onto the inner wall of the drying bin 1 through the two groups of crushing boxes 25 to make the fish oil calcium alginate microcapsules remaining on the inner wall of the drying bin 1 fall off. Then, the connecting valve 3 is opened to discharge the dried fish oil calcium alginate microcapsules into the storage box 4, thereby improving the practicality of the equipment.

[0059] The main functions achieved by the present invention are: improving the drying effect, improving the uniformity of cooling, and improving the cleaning effect;

[0060] 1. Improve the drying effect: by cooling the inside of 01 and using dry ice particles to quickly cool the fish oil calcium alginate microcapsule liquid, the water in the fish oil calcium alginate microcapsule is sublimated, and the fish oil calcium alginate microcapsule is dried quickly, reducing the impact of high temperature on the fish oil. In addition, the fish oil calcium alginate microcapsule is impacted by dry ice particles to reduce the adhesion of the fish oil calcium alginate microcapsule and improve the drying effect;

[0061] 2. Improve the uniformity of cooling: by crushing the dry ice twice, dry ice particles are formed, which facilitates the rapid and uniform cooling of the fish oil calcium alginate microcapsule liquid;

[0062] 3. Improve the cleaning effect: By spraying some dry ice particles onto the inner wall of the drying chamber, the convenience of cleaning the drying chamber is improved.

[0063] The spray drying equipment for preparing fish oil calcium alginate microcapsule samples of the present invention has common mechanical installation, connection or setting methods, which can be implemented as long as the beneficial effects can be achieved; the amount of air entering the drying chamber 1 is less than the amount of air discharged by the vacuum pump 5; the vacuum pump 5, refrigerator 7, first motor 9, delivery pump 11, atomizer 12, second motor 15, booster pump 24, cylinder 29, air compressor 32 and third motor 33 of the spray drying equipment for preparing fish oil calcium alginate microcapsule samples of the present invention are purchased on the market, and technicians in the industry only need to install and operate them according to the accompanying instruction manual, without the need for creative labor by technicians in this field.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
