Semi-closed circulation spray dryer LPG-500

Semi-closed circulation spray dryer LPG-500 spray drying is a process widely used in the liquid process forming and drying
industry.

Suitable for the generation of powdered, granular solid products from solutions, emulsions, suspensions and pumpable paste liquid raw materials
.

The existing spray drying is carried out by using a high-pressure pump to polymerize the material into a mist particle directly in contact with the hot air through the nebulizer, and the drying
is completed in a short time.

Semi-closed circulation spray dryer, which is characterized by: the upper part of the spray dryer is provided with a feeding port, the lower part of the spray dryer is equipped with a cone section, the bottom of the cone section is connected to the circulating air duct, the side wall of the cone section is connected to the cyclone dust collector through the pipe, the outlet of the cyclone dust collector is connected to the inlet of the circulating fan through the pipe, the feed port of the cyclone dust collector is connected to the circulating air duct, the circulating air duct is connected to the cyclone separator, and the outlet of the circulating fan is connected to the condenser through the pipe, The outlet of the condenser is connected to the combustion system by a branch pipe, which is also connected
to a circulating duct.

The combustion system is also connected
to the air and fuel lines, respectively.

A cooler is connected to the side wall of the condenser
