Brief introduction ●Spraying drying equipment is one of the new model high efficiency industrial drying methods. It can be divided into pressure model, centrifugal model, and airflow model. The former two ones are commonly used in our country, especially in dairy industry. ●Spraying drying is to evaporate 95%-98% of water in 5-40 seconds from solution, emulsion, suspending liquid, pulp with water content of 40%-90% in hot wind into tiny particulate, then into powder or granulated products. It fits to heat sensitive material for the low temperature of liquid drops. ●Because the drying process is finished in air, the powder is hollowed or lacunaris, with good dispersibility , fluid and solubility, so to reduce the working procedures and simplified the craft flow. ●The granularity, density, moisture of the product can be adjusted in certain scale by changing the operation condition, with convenient control management. So spraying drying equipment has a bright future in industries as dairy, food, light industry, chemical industry, building material, Chinese medicine, western medicine, and biochemical industry. Work principle: after filtering, heating by steam, air enters the wind balancer at the top of drying room by fan; the hot air evenly enters drying room, and revolves in the form of tornado. Mean while the liquid is sent to the pressure spraying tip or centrifugal spraying tip at the top of the drying room, sprayed into tiny frogy drops, so the surface of the liquid in touch with hot air greatly increases,water evaporates fast, and dries the end products in short time. Dust collection system can be fixed to the equipment to special product and demand to protect air pollution and improve the environment. Equipment divisions: Divisions according to drying room: double flow, anti flow, mixed flow System composition: Material imputing system, wind heating system, tower body, air blowing system, tiny powder agglomeration, vibrating flow bed, air pressure system, and electric control system.
