ISO9001 LPG Series High Speed Centrifugal Spray Dryer

Easy Control LPG Series High Speed Centrifugal Spray Drying Machine

Descriptions

Atomizing drying machine is the high efficient drying equipment, to make dry powder or granule from liquid, emulsion, suspension and pumpable pasty liquid, especially for thermosensitive material, it can keep color, original flavor and chemical feature of raw material, and the finished dry powder or granule have good quality,purity, fluidity and solubleness.

This equipment features by high accuracy & speed & efficiency, simple production process, labor-cost saving, widely applied in the industry of chemical, food, rmacy, biochemistry, light industry,etc.

PrincipleAfter filtering and heating, the air would enter into upper air-deployer of drying tower, and then come in in hot spiral form. At the same time, the raw liquid material would be atomized by tower from upper inside, become the super tiny globule in mist type, the surface of which would the hot air fully, then finished dry powder would be achieved in short time and collected at the bottom of tower and be discharged from cyclone separator, the gas would be exhausted outside.

FeaturesFor 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 systemBefore 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 systemThe 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 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 wall5. Air exhausting and product collecting systemFor 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 systemHMI+PLC, each parameter can be displayed on the screen. Every parameter can be controlled and recorded easily.

Some Operation Issues:

1. Atomizating: Atomizing system must insure uniform spraying fogdrops.2. Hot airflow and fogdrops ng: While the hot air come into drying tower, user have to consider the air flowing way and angle. No matter co-current flow, adverse current or mixed flow, user must insure the sufficient heat exchange, which is the key way to make sure the dry efficiency.3. The angle design of pipe cone: It is pretty important to choose the suitable angle, please us for more working experience.
