High Speed Centrifugal Spray Drying Machine For Powder
Product Description
High speed drying:the surface area of liquid material is greatly
increased after atomization, achieving instantaneous evaporation of
95% -98% water in the hot air flow, drying time only takes a few
seconds, especially for heat-sensitive materials
Products achieve good uniformity, mobility and solubility, and also
achieve purity, good quality. The production process is simplified
and the operation control is convenient. For liquid materials with
the moisture content of 40-60% (special materials up to 90%) can be
dried into powder products just with one time, do not need grinding
and screening after drying, reduce production processes and improve
product purity. The product size, bulk density, moisture, in a
certain range can be adjusted by changing operating conditions,
control and management are very convenient.
The air is filtered and heated into the top air distributor of the
dryer, and the hot air enters the drying chamber evenly in a spiral
fashion. The material liquid is sprayed into a fine atomized liquid
droplet through the high-speed centrifugal nebulizer at the top of
the tower body, and can be contacted with the hot air in a very
short time and can be dried into finished products. The finished
product is continuously discharged from the bottom of the drying
tower and the cyclone, and the exhaust gas is drained by the draft
fan.
On the basis of introducing foreign advanced drying technology,
Wuxi Tianyang Drying Equipment Co., Ltd. cooperates closely with
many domestic scientific research institutes to develop and produce
various types of domestic leading high speed centrifugal spray
drying equipment by itself.
The LT series high speed centrifugal spray drying machine for
powder produced by our company has passed the appraisal of new
products in Jiangsu Province, China. It is a drying equipment
specially introduced by the Product Quality Inspection Center. It
is also a special equipment company designated by the Ministry of
Chemical Industry to manufacture high-speed centrifugal spray
dryers.
Working Principle
The working principle of LT series high speed centrifugal spray
drying machine for powder is that after the air enters the heating
device through the filter, it enters the hot air distributor at the
top of the drying chamber, and the hot air passing through the hot
air distributor enters the drying chamber evenly and rotates in a
rotating manner. At the same time, the material liquid is sent to
the high-speed centrifugal atomizer at the top of the drying
chamber, and the material liquid is atomized into extremely small
mist droplets by the centrifugal atomization disc. It can be dried
into powdered granules in a short period of time, that is finished
products.
Main Features
* Drying speed is quickly.
* The final product quality is better.
* The product has good dispersibility, fluidity and solubility.
* The production process is simple and the operation and control
are convenient.
* Air jacket cooling system is used on the drying chamber wall and
roof to prevent the material from being melted and hung on the
wall.
* The inner wall of the drying chamber adopts an air rotary purging
system to reduce the phenomenon of sticking to the wall.
* According to user requirements, the products can meet the
requirements of GMP national standards.
