CE Low Temp Lab 220v Chemical Spray Dryer Plant

China Supplier Low Temp Lab chemical spray dryer Price with spray dryer plant

The spray drying technology is the widest used in the liquid shaping technology and in the drying industry. It is most suitable for producing powder, particle, or block solid products from materials of solution, emulsion, soliquoid and pumpable paste states. Therefore, the spray drying is one of the most desired technologies when the particle size and distribution of the final products, their residual water contents, and the stocking density and the particle shape can meet the precision standards.

Principle

After been filtered and heated the air enters into the air distrbutor on the top of the dryer.The hot air enters into the drying room 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.Trough the very short time of contacting the heat air,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.
 

Features

For the LPG series high speed centrifugal spray dryer, it consists of of liquid delivery, air filtering and heating, liquid atomizing, drying chamber, air exhausting and material collecting, control system and so on, the feature for each system as bellow:

1. The liquid delivery system consists of liquid tank, magnetic filter, 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 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 efficiency filter 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 Chamber 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 SUS 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.

Ordering instruction

1. Liquid name and property: solid contents (or water contents), viscosity, surface tension and PH value.

2. Dry powder density, residual water contents allowed, particle size, and maximum temperature allowed.

3. Output, daily shift time.

4. Energy that can be supplied: steam pressure, electricity properly, fuel of coal, oil and natural gas.

5. Control requirement: whether or not the inlet and outlet temperatures should be controlled.
