Whey Concentrate Spray Drying Machine

Whey Concentrate Spray Drying Machine

1. Whey Concentrate Spray Drying Machine Brief Introduction:

Whey Concentrate Spray Dryer is a wide applied process in liquid process shaping and drying industry. This kind of Whey Concentrate Spray Drying Equipment has quick drying speed. Particularly the Centrifugal Spray Dryer Machine 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 surface area of material liquid through atomizing is increased greatly. In hot air stream, 95% to 98% of moisture can be evaporated at the moment. Especially suit for drying thermal sensitive material. The product made by the machine has good uniformity, fluidity, solubility, high pure, and high quality.

The productive process is simple and the operation, control is very convenient. For liquid containing 40 - 60% of damp(for special material, may be 90%), it can be dried to powder product through drying one time. After dried, it is not necessary to crush, sieve. So it reduces productive procedure and raises the purity of product. For the size, bulk density and moisture of product can be adjusted within certain scope through exchanging operation condition.

Principle

The hot air enters into the drying room in the spiral form and uniformly after been filtered and heated the air enters into the air distributor on the top of the dryer. Passing through the high-speed centrifugal atomizer 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 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. Hywell will design the bag filter to collect materials to reach 99.9% materials recollection. If some materials will be environment pollution, Hywell will design and manufacture the water scrubber.

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:

1.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.

2. 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.

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 top of tower and it can regulate air flow rotation angle according to the specific condition to 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 layer is rock wool

The middle of tower have the manhole to view and be convenient to clean and maintain the tower. For thetower 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, 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.

6. Control system

HMI+PLC, each parameter can be displayed on the touch screen. Every parameter can be controlled and recorded easily. but it also can use button to reduce client investment.
