SPD-P5 Pilot High Speed Centrifugal Spray Dryer

SPD-P5 Pilot High Speed Centrifugal Spray Dryer

Working principle of the equipment

SPD-P5 spray dryer is a drying equipment suitable for the liquid material with low temperature point and high viscosity, which has been improved several times on the basis of domestic and foreign spray dryers. The working principle is: cold air is filtered through the filter, then enters the heater, is heated to a certain temperature, and then enters the air distributor at the top of the spray tower, and the hot air spirally flows to the bottom of the tower. The liquid is pumped to the centrifugal atomizer at the top of the tower body, and the liquid is torn into extremely small mist droplets. The liquid droplets and the hot air are in parallel contact, and the heat exchange is fully performed. The water content is rapidly vaporized and evaporated, and dried in a very short time as a finished product. The finished product is separated by a cyclone and discharged, and the exhaust steam is discharged by an induced draft fan.

Features

1. The drying time of the equipment is short, the material is only 5 seconds from the entrance and exit, and the general active ingredients are not destroyed.
2. The spray tower has large diameter, can adapt to the drying of various materials, and the inlet air temperature can be adjusted, and the working range is wide.
3. The equipment is fully equipped to meet the requirements of the production process to the greatest extent.
4. Simple operation, wide adaptability, no need for professional operators.
5. The unique air inlet spiral distributor is the company's patent, which can ensure that the air volume is absolutely even down on the circumference of the tower body, and the material sticking wall is minimized.
6. Advanced and convenient cleaning door can facilitate the operation of the workers, and at the same time ensure absolute sealing, so that the material does not stick to the wall, and a cleaning door is arranged on the tower body to facilitate all-round cleaning.
7. The tower is absolutely mirror polished without any dead angle. One is to avoid sticking, and the other is to facilitate cleaning.
8. The inlet air temperature is controllable and can fully satisfy the drying process of the material.
9. All pipes and cyclones are equipped with a quick opening cleaning port.
10. The heater is changed into a U-tube form, which can overcome the defects of the weld cracking caused by the thermal expansion and contraction of the heating pipe. The U-shaped tube has an outer casing to avoid air leakage between the pipe and the tube plate. The fins are made of aluminum alloy, which improves the heat transfer coefficient and heat transfer efficiency.
