Lab High-speed Centrifugal Spray Drying Equipment

Principle

LPG Spray drier is a wide applied process in liquid process shaping and drying industry. This kind of Lab Liquid Drying Machine has quick drying speed. Particularly the Pharmaceutical Spray Drier is suitable for producing powder, granule or block solid product from solution, emulsion, suspending liquid and pumped paste liquid.

Some special materials need to dry again by the GFG fluid bed dryer or FG Fluidized dryer as batch to batch ,or connect vibration fluid bed dryer as continuous drying to reduce the final moisture , when hywell engineer design the LPG spray drying machine and decide whether to add this second step drying machine base the materials characteristic.

Through the very short time of contacting the pure heat air, the materials can be dried into the final products by seconds. The final products will be discharged continuously from the bottom of the drying tower and from the cyclones. The waste gas will be discharged from blower.

LPG series high speed centrifugal spray dryer consists of liquid transfer system, air filter system and heating system, liquid atomizing, drying tower, air exhausting and material collecting, control system and so on, the feature for each system as bellow:

Liquid transfer system -The liquid delivery system consists of liquid tank, pump and so on as to ensure the liquid enter into the atomizer smoothly.

Air filtering system and heating system-air should pass through the Pre&post filter first, and then enter the heater for heating. To ensure the drying medium enter into the drying chamber with high purity, the heated air should go through the high temperature high efficiency filter (HEPA-Optional) . For the heating method, there are electrical heater or steam radiator, gas furnace. Which method to choose depends on the customer site conditions.

Atomizing system-the atomizing system consists of high speed centrifugal atomizer with inverter and so on. The powder from the high speed centrifugal atomizer is between 40-120 microns.

Drying tower system- The drying chamber consists of the spiral shell, hot air distributor, main tower and relevant fittings. Drying tower: The inner wall is SUS mirror sheet, ad welded by the arc welding. The insulation layer is rock wool .

Product collecting system and Air exhausting -For the material collecting system, there are several types. Such as cyclone, cyclone + bag filter, cyclone+ bag filter +water scrubber and so on. The method is depending on the material property itself. For the filtering system for the outlet air, we have filter on request.

Control system-HMI+PLC, each parameter can be displayed on the touch screen. Every parameter can be controlled and recorded easily.

Features

1. Machine materials : AISISUS304 , AISISUS316L, and other material .

2. For the electrical component , we mainly use international brand such as ABB ,Siemens or Schneider.

3. Smooth running, reliable performance, easy operation.

4. Highly polished inner and outer surfaces of the machine, no dead comer, easy to clear, no cross contamination.

5. Control system has more choices, such as push button , HMI+PLC and so on.

Attention to order
1. When order the LPG series high speed centrifugal spray dryer, Client need to supply the materials name.

2.When order the LPG series high speed centrifugal spray dryer, Client need to supply the materials characteristic that include materials HP, Maximum withstand temperature and so on.

3.When order the LPG series high speed centrifugal spray dryer, Client need to supply the materials primary moisture and final moisture (%).

4.When order the LPG series high speed centrifugal spray dryer, Client need to supply the treating capacity per hour.

5.When order the LPG series high speed centrifugal spray dryer, Client need to supply heating way, if it use steam heating, client need to supply the steam pressure and steam capacity.

6.When order the LPG series high speed centrifugal spray dryer, Client need to decide which kinds steel for machine-304 stainless steel or 316L stainless steel (Hywell also give suggestion for the stainless steel model base the materials HP).
