Horizontal Spray Dryer

 WPG Series Horizontal Spray Dryer

Advantages of Horizontal Spray Dryer:

1. Space-saving

Vertical dryer is very high because atomized droplets and hot wind are all from top to bottom, which means the height should be high enough to make sure products are dried when they are discharged from the bottom. What’s more, vertical dryer uses hot air for powder transportation. In order to reduce the wastage and to meet the environmental requirements, it needs to be matched with cyclone separators and bag dust collectors, which makes the entire machine occupy a lot of area. It has several discharging gates, but only the finest powder could reach the final bag dust collector, which means powders discharged from different gates are with different sizes and moisture content.

Comparatively, the atomization, drying, low speed circulatory scraper powder transportation, dust collection and products discharging of the horizontal dryer are all done in a compact drying oven, so it just needs small space for installation. Compared with the vertical dryer with evaporation capacity of 1900kg/h, the horizontal dryer is no higher than 12 meters. What’s more, the cleaning of the inner equipment is safer and easier.

2. Low Heat Loss

Since all the processes are finished in sequence in a compact drying cabinet, and the thermal insulation layer (with the thickness of 100mm) which covers the entire cabinet and the air-exhausting pipes could minimize the heat loss of the equipment. You will not feel hot when touch the surface of the working equipment. 

3. Energy-saving

The horizontal spray dryer is equipped with a recovery system of exhausts heat, which could reduce the energy-consumption, and increase the comprehensive utilization rate of heat.

Compared with high heat loss vertical dryer which is not equipped with heat recovery system, the evaporation capacity of horizontal dryer is just about 1300 kcal per kilogram water. If we compare the 2 dryers with the same standard of 1000kg/h evaporation capacity, the vertical dryer will consume heat 430000 kcal more per hour than that of horizontal dryer, which means the vertical dryer needs 86kg more standard coal(1kg coal=5000 kcal heat) or 50.6 m3 more natural gas (8500 kcal/m3). The horizontal dryer could save 35% of total energy consumption of the vertical one's.
