Pressure Spray Dryer YPG

Item Code:YPG Features:To melt the material, like wax, PE wax, resin, etc. To cool the air and enter into the spray tower, To feed and spray the melted liquid into spray tower, The melted material liquid contact with the cold air and will be solidified small round particles/round granulaes.
  • Description

I. Working principle and configuration options:
The solution, emulsion, suspension liquid or slurry are sprayed into fine beads in the hot air, going down from the top of the drying chamber to the bottom, the water will be evaporated to and the product becomes small granular product.

Induce hot air from the top of drying tower, at the same time, pump the material liquid to the top of the tower by high pressure pump, the feeding solution becomes fine beads or small droplets through the pressure nozzle(s). When the droplets meet the high temperature hot air, the water will be evaporated immediately, and the material liquid is dried into dry product in a very short time, the product is discharged from the bottom of the drying tower, or from the cyclone (depend on the configuration). When the hot air contacts with the droplets, the temperature declines significantly, and the humidity increases greatly, and then will be exhausted by exhaust fan. The fine powder in the air will be collected through different separating devices

There’re different fine powder separation and recovery devices, such as cyclone (the common type and various combination type), bag filter, cyclone + bag filter, cyclone + wet scrubber, and bag filter + wet scrubber etc. We should different fine powder separation and recovery devices as per the characteristics of product and requirements of customer.

Depend on the product features and requirements, we might install secondary drying and cooling system (such as ZLG vibration fluid bed or pneumatic transportation), formulation system or powder sieving system etc after the spray dryer, or dehumidifier.

The particle size of the product from pressure spray dryer is normally within the range of 120mesh to 20 mesh. If bigger particles are required, we suggest FL Fluidized Granulator or re-combined agglomerator.

 

 

II. Features of our equipment:

The designs of our spray dryer are advanced in China, as well as worldwide. If we compare the important parameters of our spray dryers and some famous brand in the world, such as final moisture content, color, flavor, particle size, solubility and bulk density etc, they are very close, or sometimes, ours are even a little better. A lot of customers have achieved their desired results with our equipment.

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.
For the products which heat sensitive temperature is more than 110°C, the process specifications is about the same with the standard specifications.
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 YPG2000 for drying food, the drying tower is about equivalent to the standard one of YPG4000 or of YPG6000 (vary as per the properties of the product).
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
4. 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.

5. 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.
6. Configuration: Please refer to the flowcharts and instructions
7. 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.

VI. Optional Configurations

1. Pneumatic transfer and cooling: Some production need to be transported to distant packaging workshop, it is suggested to use pneumatic transfer + cooling.
2. Fine powder return for granulation and agglomeration with re-combination: For the system that require fine powder return for granulation or agglomeration with re-combination, we have different configurations for different processes of different products. Please contact us for further information,
3. Configurations: The configuration of equipment is designed generally based on product characteristics, process requirements, energy supply and other requirements, such as environmental protection requirements or height restrictions and other specific requirements. The real configuration might be changed flexibly according to customer requirements. 
3.1: Heat source: electricity, electricity + steam; high pressure steam; direct hot air furnace; indirect hot air furnace; and thermal oil furnace etc. The fuel of the furnaces might be any kinds of fuel (diesel oil, heavy oil, natural gas, LPG or coal, etc.), or solid fuel (any combustible material). Please specify when to finalize an order.

3.2: The air inlet could be direct air inlet, and also could be waste heat recovery air inlet
3.3: The exhaust system could be single cyclone, two-stage cyclone, bag filter, wet scrubber or their combinations.
3.4: Others: We also provide a variety of special configurations according to the process or customer requirements, such as inner wall cooling, conical part cooling, product cooling, scraper, sweeper or some special types drying tower.
