LPGSeries Centrifugal Spray DryerIt is the most widely used process in the liquid forming process. It is suitable for use fromProduce powdered or granular solid products from solutions, emulsions, suspensions, and pasty liquids.Therefore, when the particle size distribution, residual moisture content, bulk density, and particle shape of the finished product all meet precise standards,Centrifugal spray dryingIt is an ideal drying process, and this series of spray dryers can be widely used in industries such as food, chemicals, pharmaceuticals, and ceramics.

After passing through an air filter, the air enters an air heater. The heating methods of the air heater include hot air furnaces, electric heating, steam heating, etc. Once the air is heated to a specified temperature, it enters the hot air distributor tangentially. After being processed by the hot air distributor, the air enters the drying chamber uniformly and in a spiral manner. At the same time, the feed liquid is atomized by the atomizer into droplets of 25-60 μm. When the droplets come into contact with the hot air, they rapidly vaporize and dry into powder or granular products. The dried powder or granular products fall onto the conical walls of the drying chamber, slide down to the conical bottom, and enter the powder collection cylinder. A small amount of fine powder flows with the air into a cyclone separator for separation. Finally, the exhaust gas is discharged through the fan outlet or enters a wet scrubber before being discharged.

Changzhou LimaLPGSeriesA high-speed centrifugal spray dryer has the following advantages:

1、Spray dryingFast speed: after atomization, the surface area of the liquid greatly increases. During contact with hot air, 95%-98% of the moisture can be evaporated instantly, with the drying process taking only a few seconds. This is especially suitable for drying heat-sensitive materials.

2. The product exhibits good uniformity, flowability, and solubility. The higher the purity, the better the quality.

3、Spray dryerThe production process is simplified, and operation and control are convenient. Liquids with a moisture content of 40-60% (up to 90% for special materials) can be dried into powder or granular products in a single step, eliminating the need for crushing and screening after drying. This reduces production steps and improves product purity. The particle size, bulk density, and moisture content of the product can be adjusted within a certain range by changing operating conditions, making control and management highly convenient.
