1, BH-Z series Chinese medicine extract spray dryer - equipment overview

The traditional Chinese medicine extract spray dryer device is a centrifugal spray drying technology used in the drying of specific materials. The high-speed centrifugal atomizer is used to atomize the viscous liquid material, and the material is in full contact with the hot air to complete the instant drying and form a powder. Drying device for finished or small granular products, mainly used for drying heat sensitive liquids, solving traditional Chinese medicine extracts, plant extracts or spray drying of materials with similar properties.

The high-speed centrifugal atomizer liquid of the Chinese medicine extract spray dryer is uniformly atomized into a very fine droplet mist group under the high-speed rotation of the high-speed centrifugal atomizing atomizing disk, and the heat-dissipating wind blown in the tower and the fan After passing through the air filter, the heater is heated to the required inlet air temperature requirement, and the hot air duct is sent to the fan to enter the drying tower, and the mist is contacted to rapidly evaporate the water and dry to form a product, and the dried product and the exhaust gas are dried. The gas bottom separation is carried out from the bottom of the tower to the cyclone. The lower part of the cyclone is collected by vacuum into the receiving cylinder, separated by cyclone, and the collected exhaust gas and the uncollected fine products are pumped into the dust collector by the induced draft fan. After the exhaust gas passing through the dust remover passes through the air cooler, it is discharged by the induced draft fan.

The medium drug substance is a heat sensitive material, and the excessive temperature directly affects the material property. In order to meet the moisture requirements of the materials, a certain drying time must be ensured. The Chinese herbal extracts often contain polysaccharides or low-melting components, which melt at the temperature of the drying chamber and adhere to the drying chamber, so they are designed as a jacketed air cooling system. The natural wind is used to take away the heat of the jacket, and the wall temperature is lowered to a suitable temperature by adjusting the air volume.

2, BH-Z series Chinese medicine extract spray dryer - equipment advantages

(1) The straight section of the main tower is designed as a 3-layer structure, and the insulation layer is designed between the jacket and the cover, which not only saves energy but also prevents the work site from being too hot. The hot air generated after the main tower cools the jacket enters the air inlet of the blower. This can save energy, improve the working environment and reduce the energy consumption of the central air conditioning of the factory.

(2) The hot water or alkaline water of the main tower and pipeline cleaning can be recycled and reused.

(3) Steam control uses a steam valve to save steam.

(4) Electric heating adopts constant temperature control to save power.

(5) The main tower blower and induced draft fan adopt frequency conversion control, which can save energy.

(6) The motor uses a secondary energy-efficient energy-saving motor.
