Spirulina centrifugal spray dryer for health care products

Description of Spray Dryer:

Centrifugal Spray Dryer is widely used for making liquid to powder. It is suitable for producing powder products from solution, emusion, soliquoid, and pumpable paste materials. So when the size, final moisture, bulk density and shape of patrticles must meet the accurate standard, centrifugal spray drying is an ideal drying process.

The hot air enters into the drying room of LPG Series Centrifugal Type Spray dryer  in the spiral form and uniformly. Passing through the high-speed centrifugal sprayer on the top of the tower, the material liquid will rotate and be sprayed into the extremely fine mist liquid beads. Through the very short time of contacting the heat air inside the LPG Spray Dryer, the materials can be dried into the final products. 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. Hywell will design the bag filter to collect materials to reach 99.9% materials recollection of the LPG Spray Dryer. If some materials will be environment pollution, Lead machinery will design and manufacture the water scrubber.
 

Features of spray dryer:

For the LPG series high speed centrifugal spray dryer, it consists of 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:
1.   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.
2.Air filtering system and heating system
  Before the fresh air enter into the heater, it should pass through the Pre&post filter first, and then enter the heater for heating. For the heating method, there are electrical heater or steam radiator, gas furnace and so on. Which method to choose depends on the customer site conditions. 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) before enters the drying chamber.
3. 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.
4. Drying tower system
 The drying chamber consists of the spiral shell, hot air distributor, main tower and relevant fittings.
The Spiral shell and hot air distributor: the spiral shell and hot air distributor at the air inlet of the tower top can regulate air flow rotation angle according to the specific condition, guide the air flow inside the tower effectively and avoid the material stick on the wall.in the middle there is the position for installing the atomizer.
 Drying tower: The inner wall is Stainless steel mirror sheet, ad welded by the arc welding. The insulation is rock wool.
The tower is manhole and view port as to convenient to clean and maintain the tower. For the Tower body cross interface, pipe elbow are arc butt design, reduce dead angle; sealed type.
The main tower is equipped with air hammer, controlled by the pulse, and hitting the main drying tower timely as to avoid the dust stick on the wall
5. Air exhausting and product collecting system
 For the material collecting system, there are several types. Such as cyclone, cyclone + bag filter, bag filter, cyclone +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.
6. Control system
HMI+PLC, each parameter can be displayed on the screen. Every parameter can be controlled and recorded easily. but it also can use button or touch screen.
