LGZ High-speed Centrifugal Spray Dryer

Overview

  The LGZ series high-speed centrifugal spray dryer can spray-dry solutions, emulsions, suspensions, and paste-like materials into dry powder. It features fast speed, high efficiency, and fewer process steps. It preserves the color, taste, and aroma of materials, and the resulting dry powder has good solubility and high purity. The equipment provides a good operating environment and basically achieves automated operation.

Working Principle

  The purified and heated hot air enters the drying tower evenly in a spiral pattern through an air distributor. Meanwhile, the liquid material is torn into fine droplets by centrifugal force through a high-speed rotating atomizing disc, greatly increasing the specific surface area. The droplets and hot air come into co-current contact inside the tower, and the moisture evaporates rapidly within seconds to complete drying. The resulting solid particles settle at the bottom of the tower and are discharged, while the exhaust gas carrying fine powder and water vapor is discharged to the atmosphere after the powder is recovered by devices such as a cyclone separator, thus forming a continuous and efficient drying cycle.

Features

  The core advantage of the high-speed centrifugal spray dryer lies in its extremely fast drying speed. After atomization, the surface area of the feed liquid increases dramatically, allowing moisture to evaporate within just a few seconds to a dozen seconds. This characteristic makes it particularly suitable for processing heat-sensitive materials, effectively preserving their color, aroma, taste, and activity. At the same time, the finished product consists of spherical particles with excellent uniformity, flowability, and solubility, as well as high purity and good quality. In addition, the production process is simplified: drying into powder can be completed in a single step, eliminating subsequent crushing and screening procedures, and the operation and control are convenient.

Applications

  It can be widely used in chemical, petrochemical, metallurgical, food, pharmaceutical, building materials, ceramics, forest chemical, and other industries. In addition, the equipment can also heat and melt special materials such as polyethylene wax, biological pesticides, and compound fertilizers, followed by cold-air shaping and granulation.
