High Speed Centrifugal Spray Drying Machine Custom For Organic Solvent

High Speed Centrifugal Spray Drying Machine Custom Spray Drying For Organic Solvent

Descriptions

SHENGMAN spray dryer is a wide applied process in liquid process shaping and drying industry. Particularly it is suitable for producing powder, granule or block solid product from solution, emulsion, suspending liquid and pumped paste liquid. Therefore when the distribution of granule size, final moisture, bulk density, granule shape of finished product must be conformed to accuracy standard, the spray drying is an ideal process.

Principle

The air is through the filter and heater, the air distributor which enters the dedicator top, the hot air takes the form of spiral
and enters the dedicator evenly. The material liquid , from the material liquid trough from the at odds with the community or the leadership atomizer for the dedicator top of pump sending through the filter, make the material liquid gush out into an extremely small calorific drop, material liquid and hot air flow and keep in touch, moisture evaporate rapidly, within extremely short time dry to become finished product, finished product discharge by dry tower bottom and whirlwind separator, the waste gas is discharged by the air 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.

Centrifugal spray atomizer Features

1. High speed drying. The surface area of Raw Material liquid increased a lot after atomization through nebulizer, 95%-98% of moisture will be evaporated in high temperature airflow in a flash, only needs seconds time.
