LPG Chicken/Beef/Meat Powder Spray Dryer

Descriptions

Spray drying is the technology most widely used in the liquid technology shaping and in the drying industry. The drying technology is most suitable for producing solid powder or particle products from liquid materials, such as: solution, emulsion, suspension and pumpable paste states. For this reason, when the particle size and distribution of the final products, residual water contents, volume density and the particle shape must meet the precise standard, spray drying is one of the most desired technologies.

Principle

After been filtered and heated the air enters into the air distributor on the top of the dryer. The hot air enters into the drying room in the spiral form 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. Through 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.

Remarks:
1. Nominal water evaporation capacity: It is calculated according to the inlet air temperature of 350°C, and the exhaust

air temperature of 85-90°C

2. Standard specification: The specifications listed above are named based on nominal water evaporation capacity.

3. Process specifications: For specific equipment, we normally name the equipment as per the specific processing

parameters and requirements.

4. For the products which heat sensitive temperature is more than 110°C, the process specifications is about the same

with the standard specifications.

5. For most food or the other products which heat sensitive temperature is normally low, the process specifications are

about equivalent to 2-3 times of the standard specifications. Such as LPG2000 for drying food, the drying tower

is about equivalent to the standard one of LPG4000 or of LPG6000 (vary as per the properties of the product).

6. For the products with high heat sensitive temperature, the inlet air temperature could be up to 450°C or even higher,

the process specification is smaller than the standard specifications. But the requirements of the drying tower and

relative configurations should be higher if the air inlet temperature is more than 450°C

7. Product yield: We provide a variety of fines collection and product recovery devices as per customer requirements

and product characteristics, so to ensure it meets customer requirements.

8. Test: We have the most advanced trial facilities in China to make trials for the customers, so to ensure that the

equipment reaches the customer requirements in the contract.

9. Configuration: Please refer to the flowcharts and instructions

10. Advanced design: we are considering the customer’s requirements, low investment, low running cost and energy

saving when we make a design. If we compare our machines and some other machines, the special feature is that

our machine is design for energy saving. For the medium and large specification equipment, the thermal efficiency of

our design is normally around 37 - 50%, i.e., around 2.0-2.7kg of steam to evaporate 1 Kg water.

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