AI Technical Summary
In the preparation of solid material microcapsules, the existing microcapsules have low drying efficiency, resulting in the failure of droplets to form quickly, making it easy to form large particles, affecting the quality of the product.
A granulation mechanism on a microcapsule spray granulator is designed, including a left mounting roller, a right mounting roller and a conical roller. The material is sprayed through the spray nozzle and combined with a strong airflow. The material moves from the small-diameter end to the large-diameter end in the roller. The airflow hits the flow diversion recess for drying, and the dry airflow is discharged from the exhaust hole, which delays the material discharge speed, and uses a spiral guide groove to form and discharge the material.
By increasing the frequency of material rolling in the drum, the drying process of liquid particles is significantly accelerated, the forming efficiency of material is improved, the generation of unqualified large particles is reduced, and the quality of the product is improved.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of food processing and relates to a granulating mechanism on a microcapsule spray granulating machine. Background Art
[0002] Microcapsule spray granulator is a processing equipment for preparing microcapsules from solid food raw materials. Solid materials enter the granulation chamber by spraying, and are generally formed in the granulation chamber by scraping, rolling, kneading, etc., and then dried to obtain microparticles. Compared with the microcapsule preparation of liquid materials, the process required for the microcapsule preparation of solid materials requires an additional drying process. At present, most of the microparticles are formed by rolling and scraping the materials onto the forming plate. The solidification efficiency of droplets on the forming plate is low, and the inability to quickly form will cause the droplets to aggregate and form large particles. Therefore, a certain amount of unqualified large particles will be formed. Utility Model Content
[0003] The purpose of the utility model is to provide a granulation mechanism on a microcapsule spray granulator in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to improve the material drying efficiency.
[0004] The purpose of the utility model can be achieved through the following technical solutions: a granulation mechanism on a microcapsule spray granulator, characterized in that it includes a frame, a left mounting roller fixed on the frame, a right mounting roller fixed on the frame and a drum, the drum is rotatably connected between the left mounting roller and the right mounting roller, the drum is conical, the left mounting roller is connected to the large diameter end of the drum, the right mounting roller is connected to the small diameter end of the drum, a spray nozzle and a dry air inlet pipe are installed on the right mounting roller, and a plurality of exhaust holes are opened on the left mounting roller; there is a gap between the outer peripheral surface of the left mounting roller and the inner wall of the drum, the outer wall surface of the left mounting roller has a spiral guide groove, and the left mounting roller has a discharge hole.
[0005] Furthermore, a guide recess is provided in the middle of the left mounting roller, each exhaust hole is located outside the guide recess, and the outlet of the drying air inlet pipe faces the guide recess.
[0006] The spray nozzle is connected to the strong air flow inlet pipe and the liquid material feed pipe. The two are mixed and sprayed onto the inner wall of the small diameter end of the drum. There is a gear ring outside the drum. The motor drives the drum to rotate. The material moves from the small diameter end to the large diameter end in the drum. The airflow used for drying hits the guide groove and returns in the drum, and finally is discharged from the exhaust hole. While quickly drying the material, the material discharge speed is delayed. Under the double combination, the dried granular material is formed under the action of the spiral guide groove and finally discharged from the discharge port. This method increases the frequency of the material rolling in the drum and accelerates the drying of liquid particles. BRIEF DESCRIPTION OF THE DRAWINGS
