Spray a can complete drying and granulation equipment. Can be adjusted according to process requirements of feed pump pressure, flow rate, the size of the orifices of the desired size by a certain percentage of spherical granules. The working process of the material was passed through a high-pressure diaphragm pump input, corn starch processing equipment models, spray or mist, and then dropped with the hot air flow, hot corn starch processing equipment, the majority of particles from the bottom discharge opening collection, waste gas and tiny powder isolated by the cyclone, corn starch processing equipment, exhaust gas discharged from the exhaust fan, corn starch processing equipment cases, powder collected by the cyclone located in the lower end of the tube pollination, at the outlet of the fan can be equipped with two stage dust means more than 96-98% recovery. The tower portion of its contact with the material, pipes, separator material, are used SUS304 production. Between the tower inside the housing there is enough insulation, filler material is ultra-fine glass wool, with observation tower doors, mirrors, lighting and control instruments, the electrical control console control and display. Its source device using steam heating or electric heaters, easy to operate, start fast, compact, clean, clean hot air and so on. Also in the electrical control cabinet control electric heater is equipped with adjusting means, the inlet temperature is not adjustable. The lack of electricity can be used for heating or steam coal, fuel stove, etc., partially or completely replaced by electric heating devices. In the spray drying operation, the following conditions, there is a potential fire or explosion hazard. Products and air dry (or drying medium) ① treated to form a combustible mixture; ② feed solution containing flammable solvents; ③ equipment failure caused fire occurrence (spark). Therefore, when the spray-drying apparatus design, all possibility of fire or explosion must be considered, relying on margins and explosive detection dryer design of each set to find a signal fire or explosion hazard; of course, but also consider fire equipment.
