LPG Series High-speed Centri-fuge Atomizing Drier (3)

LPG High-speed Centrifugal Spray Dryer

Some special materials need to dry again by the GFG fluid bed dryer or FG Fluidized dryer as batch to batch ,or connect vibration fluid bed dryer as continuous drying to reduce the final moisture , when hywell engineer design the LPG spray drying machine and decide whether to add this second step drying machine base the materials characteristic.

Principle

For the LPG 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 of LPG Series Spray Drier 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 of Liquid Centrifugal Spray Dryer

  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 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. but it also can use button or touch screen.

Main Features:

1. The drying speed is high when the material liquid is atomized, the surface area of the material will increase greatly. In the hot-air flow,95%-98% of water can be evaporated at a moment .The time of completing the drying is only several seconds. This is especially suitable for drying the heat sensitive materials.

2. Its final products own the good uniformity, flow ability & solubility. And the final products are high in purity and good in quality.

3. The production procedures are simple and the operation and control are easy. The liquid with moisture contents of 40-60% (for special materials, the contents might be up to 90%).can be dried into the powder or particle products once a time.

4. After the drying process, there is no need for smashing and sorting, so as to reduce the operation procedures in the production and to enhance the product purity.

5. The product particle diameters, looseness and water contents can be adjusted through changing the operation condition within a certain range. It is very convenient to carry out control and management .

Applications       
Chemical Industry: Sodium fluoride(potassium),alkaline dyestuff and pigment, dyestuff intermediate, compound fertilizer, formic silicic acid, catalyst, sulphuric acid agent, amino acid, white carbon and so on
Food Industry: Fatty milk powder ,protein, cocoa milk powder, substitute milk powder, egg white(yolk), food and plant, oats, chicken juice, coffee, instant dissoluble tea, seasoning Sugar, corn syrup, corn starch, glucose, pectin, malt sugar, and etc.

Attention to order
1. When order the LPG series high speed centrifugal spray dryer, Client need to supply the materials name.

2.   When order the LPG series high speed centrifugal spray dryer, Client need to supply the materials characteristic that include materials HP, Maximum withstand temperature and so on.

3.   . When order the LPG series high speed centrifugal spray dryer, Client need to supply the materials primary moisture and final moisture (%).

4.   When order the LPG series high speed centrifugal spray dryer, Client need to supply the treating capacity per hour.

5.   When order the LPG series high speed centrifugal spray dryer, Client need to supply heating way, if it use steam heating, client need to supply the steam pressure and steam capacity.

6.   When order the LPG series high speed centrifugal spray dryer, Client need to decide which kinds steel for machine-304 stainless steel or 316L stainless steel (Hywell also give suggestion for the stainless steel model base the materials HP).

Quality control

In order to ensure quality of product, we focus on user 's requirements and control improvement and enhancement quality of products .The quality assurance mainly focus on the processes of ensuring production readiness inspection, control of raw materials and components, process control, critical parts, important parts of quality control, assembly quality control, process control testing, measurement equipment control. Pay close attention to the implementation of the quality assurance work, strictly to three inspection system of self-checking, mutual inspection, special inspection. The key point of Quality assurance is focuses on critical parts, important parts of quality control, the quality standards required by ISO9000 quality control procurement documents in order to clarify its status and acceptance of quality standards for company's re-inspections ; For critical parts and important that the key processes of identification and corresponding technical documentation, control by "the implementation of key quality control process", and complete, accurate and complete original records. Difficulties in quality assurance is a special process control, quality assurance is mainly painting, has developed a special process (painting) process documents, take the appropriate technical measures, to quality assurance.

In the production process, we pay close attention to quality control of each process. Every component, every process was strictly controlled. Enhanced the quality inspection process, the establishment of the necessary quality control point, the process by a full-time staff and quality inspector for inspection and supervision. Improved testing procedures and operating instruction.
