The Spray Granulation Coating Machine Multi-functional One-step Granulator utilizes a new type of inflatable sealing ring, simplifying operation and ensuring airtightness. The sealing ring is made of silicone rubber, offering a wide temperature application range from -50°C to +220°C, allowing the Spray Granulation Coating Machine to be used in more experimental and industrial applications. The granulation principle of the Multi-functional One-step Granulator: The top spray device consists of a conical material trough and an expansion chamber. The material forms a fluidized motion from bottom to top and vice versa. In the conical pot, the material moves back and forth, creating a fountain-like fluidized state. The spray gun sprays the liquid, causing the material to first form a liquid bridge and then a solid bridge, resulting in large particles. Multiple atomization head installation ports are equipped at the top of the expansion chamber, which can be used to spray atomized liquids during the granulation and coating process.

The spray granulation coating machine's inflatable sealing ring: The expandable portion of the sealing ring is naturally retracted into the concave groove of the sealing door. When the equipment requires sealing, air is inflated into the sealing ring bladder through the inlet and exhaust nozzles. The sealing ring bladder deforms under internal pressure, with the concave part bulging outward, tightly contacting the opposite sealing surface to achieve sealing. To release the sealed state, air is then expelled through the nozzles, causing the expanded part of the sealing ring to retract back into the groove and return to its natural state, detaching from the sealing surface.
