Powder Granule Equipment

The cooling spray granulation device is a product with strong practicability and pertinence. It is the equipment carefully designed by our company to "tailor" the cooling granulation of low melting point materials.

1. Fluidized bed cooling devices cooled by ambient air are suitable for two-stage cooling methods, and pneumatic conveying systems with cold conveying air can also be used.

2. The design selection should also be based on the requirements of finished particle size, which can range from fine particles, coarse particles to coarser particles, and coarse particles to coarser products.

The cooling process is achieved by introducing sufficient low-temperature air. The molten material is atomized or granulated by a rotary atomizer equipped with a specially designed impeller, or it can be atomized using a pressure nozzle or a dual flow nozzle. Spray cooling is used in chemical, food and pharmaceutical industries. It is a suitable method to process molten materials into free flowing particles and control particle size.

1. The independently designed vortex air distributor, based on the basic principles of aerodynamics and fluid dynamics, enhances the mass and heat exchange between cold air and hot melt droplets. At the same time, the system adopts a reverse parallel flow approach to ensure that the hot melt droplets are fully and effectively cooled by the cold air, completing the cooling granulation process.

2. The granulation tower adopts a jacket air cooling device to ensure that the inner wall of the granulation tower does not experience the phenomenon of "hot melt hanging" of materials.

3. The "low cap" exhaust structure device ensures that more than 90% of the finished products are collected at the bottom of the granulation tower, with only a small amount of micro powder entering the cyclone separator, reducing the gas-solid separation pressure of the cyclone separator.

4. All the air entering the granulation tower system is filtered through three stages of primary, medium, and sub high efficiency, with a purification level of over 300000.

5. The inner wall of the granulation tower, the powder outlet pipeline, and the cyclone separator are made of SUS304/BA mirror stainless steel plates. All welds are treated with argon gas protection welding, and the welds are ground and polished with a polishing accuracy of 0.3 μ, effectively preventing the phenomenon of "powder and material accumulation" in the pipeline. The powder outlet pipeline and cyclone separator are equipped with quick opening cleaning ports, which are easy to disassemble, clean, disinfect and sterilize, fully meeting food hygiene requirements.

6. The product recovery system is equipped with a secondary fluidized bed cooling and drying device to cool and dry the micro powder that has completed spray granulation. The finished product that has been fully cooled and dried has good fluidity and low temperature, and can be packaged directly.
