How the inlet and out air temperature of the spray dryer controls the spray dryer equipment is dried by using the hot air blown in to achieve aqueous solution/suspension liquid mist.
the heat air enters the drying tower from the mouth of the tower during the drying process, and the exhaust gas after the drying work is exhausted by the fan.
of the spray drying equipment, the control of the hot air temperature and exhaust temperature when hot air enters the tower is very important, which determines the quality of the product and the density of the drying pine, etc., so it needs to be strictly controlled.
1. In the operation of spray drying equipment, the exhaust temperature is related to the moisture content of the product and should be determined according to the moisture content of the product.
the hot air temperature, the higher the thermal efficiency, the better the economic benefits.
but too high a hot air temperature can cause poor product quality.
2. In the operation of spray drying equipment, the hot air temperature will affect the loose density of the product.
high temperature hot air has produced a low pine density change, because the hot air has a drying effect, so that the surface of the particles hardened and the residual moisture expansion, and formed a balloon-like hollow particles.
if a high pine density (low ratio capacity) is required, or solid particles are required, the design should not be designed with high temperature hot air in contact with newly formed fog droplets.
