                       zinc sulfate monohydrate spray dryer        

 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 powder or 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 screw pump or peristaltic pump, the feeding solution becomes into fine beads or small droplets through the atomizer. 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.

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 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).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°C4. 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 instructions7. 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.
