LPG high-speed centrifugal spray drier is a kind of efficient and commonly used drying equipment, and the corresponding characteristics are introduced as follows.

First, the working principle：

The working principle of LPG high-speed centrifugal spray drier is based on centrifugal atomization and hot air drying technology. Specifically, the air enters the air distributor at the top of the dryer after passing through the filter and the heater, and uniformly enters the drying chamber in a spiral shape. At the same time, the feed liquid is pumped to the centrifugal atomizer at the top of the dryer through the filter and sprayed into tiny mist droplets. These droplets come into parallel contact with hot air, and the water evaporates quickly, thus completing the drying process in a very short time.

Second, the technical characteristics：

Fast drying speed: Because the feed liquid is sprayed into tiny mist droplets, its surface area is greatly increased, and the contact area with hot air is correspondingly increased, so it can quickly evaporate water and complete drying in a short time. Usually, the drying time only takes 5~15 seconds.

Good product quality: because the drying process is completed in an instant, the particles of the finished product can basically keep the droplets approximately spherical, so the product has good dispersibility, fluidity and solubility.

Simple operation: The production process of LPG high-speed centrifugal spray drier is simplified, the operation and control are convenient, and it is suitable for continuous control production. At the same time, the equipment is equipped with automatic control system, which can realize remote monitoring and adjustment.

Strong adaptability: the equipment can choose different drying conditions according to the characteristics of materials, such as hot air temperature and spray quantity. Therefore, it is suitable for drying a variety of materials, including heat-sensitive materials.

Third, the scope of application：

LPG high-speed centrifugal spray drier is widely used in chemical industry, metallurgy, electronics, ceramics, mining, pesticides, dyes, pigments, detergents, pharmaceutical intermediates, flue gas desulfurization, wastewater treatment and other industries. It can be used to dry all kinds of liquid materials such as emulsion, suspension, paste and aqueous solution, such as polymers, resins, carbohydrates, preserved egg products and so on.

IV. Operation and Maintenance

Precautions for operation:

Before use, check whether the pipe joint is well sealed, whether the door and observation window hole are closed and whether there is air leakage.

In the preheating process, it should be ensured that the spray head is placed at the top of the drying chamber, the bottom of the drying chamber and the discharge port of the cyclone separator are blocked to prevent cold air from entering the drying chamber and reducing the preheating efficiency.

When the spray head reaches the highest speed, start the feed pump to add the feed liquid, and the feeding amount should be gradually adjusted to the appropriate requirements from small to large.

Maintenance and maintenance:

Clean and disinfect the equipment regularly to ensure product quality and equipment life.

Check the wear of transmission parts such as bearings and bushings, and replace the damaged parts in time.

Check the atomization effect of the spray head regularly, and clean or replace it in time if it is abnormal.

V. Suggestions for purchasing：

When purchasing LPG high-speed centrifugal spray drier, the following factors should be considered:

Material characteristics: Select the suitable dryer model and parameters according to the material properties, such as hot air temperature and spray quantity.

Production capacity: select the appropriate equipment specifications and output according to the production demand.

Equipment quality: choose the equipment produced by the manufacturer with good reputation and strong technical strength to ensure the quality and after-sales service of the equipment.

Price factor: under the premise of ensuring the quality and performance of equipment, consider the price factor and choose products with higher price.

To sum up, LPG high-speed centrifugal spray drier has become an indispensable drying equipment in many industries because of its high efficiency, convenience and wide application fields. In the process of purchasing and using, factors such as material characteristics, production capacity, equipment quality and price should be fully considered to ensure the normal operation of equipment and product quality.
