Product Details
Product description
Pressure Type Spray Dryer has fast drying speed. After the liquid is atomized in the hot air stream, the surface area of the material is greatly increased. It can instantly evaporate water 95-98, and the drying time is only ten seconds to tens of seconds. It is especially suitable for drying heat sensitivity. materials.
The spray dryer has a wide pressure range. According to the characteristics of the material, it can be dried by hot air or cold granulation, which is highly adaptable to the nature of the material.
Working principle
Feed the material liquid through a diaphragm pump, high-pressure input, discharge or atomization, and then fall with hot air flow. Most of the particles are collected by the cyclone separator from the bottom discharge port, exhaust port and fine powder. The exhaust gas discharged by the exhaust fan is discharged from the lower end. The provided powder is collected in the cyclone dust collector, and it can also be equipped with a secondary dust removal device, with a recovery rate of over 96-98%.
Feature
The simple pressure spray dryer runs stably, is easy to control, and is easy to operate automatically. Pressure spray dryer is a device that can complete drying and granulation at the same time. According to the pressure spray dryer process, the pressure of the feed pump is adjusted, and a certain proportion of spherical particles is used to make the size of the flow orifice of the required size.
Care and maintenance
If the Pressure Type Spray Dryer runs for a long time or is improperly operated, there will be some aggregates in the equipment that will affect the normal operation. At this time, it needs to be shut down for cleaning. When cleaning the aggregate of the drying tower, open the cleaning door, sweep the bottom of the funnel-shaped aggregate with a long broom, open the discharge valve, and rinse with tap water. In the cyclone dust collector, we need to activate the cyclone dust collector, use a broom to clean the aggregates, and flush it with water if necessary. When cleaning the bag filter, turn on the control switch, knock, then open the cleaning door, knock on the bag filter, and finally replace the filter bag. For cleaning the mud pipeline system, open the drain valve of the two-way filter, clean the filter screen and pipeline, and then turn on the feed pump, water and raw materials, cleaning pump, regulating bag and pipeline.
After a period of operation, we need to carry out necessary inspection and maintenance of the spray granulation dryer. For the feeder system, check the filters, pipes, valves, nozzles, etc., to see if they are blocked, clean and check regularly, and replace the nozzles for wear. The feed pump should be checked for leaks, whether the pressure is normal, whether the oil level is normal, etc. For fans, check the shafts and bearings for lack of oil and heat, vibration and noise. If necessary, clean the fan blades and check the balance. For the heater, if necessary, check whether the filters of the heating pipe, washing pipe, water pump, and nozzle are normal. In addition, pay attention to whether each motor has heat, vibration, abnormal noise, etc., and whether the control cabinet instruments and electrical work are normal.
