Sterile spray drying device LPG-200

The utility model relates to the technical field of chitooligosaccharide production equipment, in particular to a sterile spray drying device.
Chitosan oligosaccharides are a type of oligosaccharide product obtained by enzymatic degradation of chitosan with a polymerization degree between 2 and 20. Due to its good water solubility and significant functional effects, chitosan oligosaccharides are widely used in fields such as food and fertilizers. Chitosan is degraded by enzyme and filtered to obtain chitosan oligosaccharide mother liquor, which also needs to be dried by spray and sterilized to obtain sterile chitosan oligosaccharide powder.
At present, the powder particles formed by the spray drying of chitooligosaccharide mother liquor are different in size, and some of them can not meet customer needs; The exhaust gas generated during the drying process carries away some chitosan powder, which can cause resource waste.
Therefore, it is necessary to design a new type of sterile spray drying device, which can prepare chitosan oligosaccharide powder with fine and uniform particles and avoid resource waste. Utility model content
Aseptic spray drying device is used to solve the problems of different particle sizes and resource waste of chitosan oligosaccharide powder prepared by the drying device. The structure of the drying device is improved to prepare fine and uniform chitosan oligosaccharide powder and avoid resource waste.
The aseptic spray drying device includes a mother liquor tank, which is connected to the spray dryer through a mother liquor pipe. The mother liquor pipe is equipped with a transfer pump and a mother liquor filter. The air inlet end of the spray dryer is sequentially connected with a heater and a blower through the air inlet pipe. The discharge end at the bottom of the spray dryer is sequentially connected with a drying tower, a cyclone separator, an induced draft fan and a spray dust collector through a ventilation pipe. The discharge end at the bottom of the drying tower is connected to the mother liquor tank through a recovery pipe. The lower side of the drying tower is sequentially connected with two heaters and two blowers through two ventilation pipes. The air outlet ends of the first blower and the second blower are both equipped with Air filter.
Preferably, the discharge end at the bottom of the spray dust collector is connected to a fertilizer tank through a discharge pipe.
Preferably, the filter element material of the mother liquor filter is polyether sulfone, and the pore size of the filter element is less than or equal to 0.2 μ m.
Preferably, the outlet end of the two blowers is also equipped with a pressure gauge.
This utility model prepares small and uniform chitosan powder particles by improving the structure of the drying device, while avoiding resource waste.
