Product Description

Introduction and Technical Parameters of Reactor

Product Introduction:

The double-cone rotary reactor is a batch-type chemical equipment integrating functions of reaction, mixing and drying. It is named after its main body, which is a double-cone rotary cylinder.

Application Fields:

It is widely used in pharmaceutical, chemical, food and other industries. For example, it is applied in processes such as drug synthesis, quartz sand acid washing, and resin production.

Product Structure:

Main Features:

The double-cone rotary reactor mainly consists of a machine base, double-cone cylinder, vacuum device, heating device, etc. The double-cone cylinder is equipped with a jacket, which can be filled with heat transfer media such as heat transfer oil. The angle between its inclined surface and the horizontal plane is generally 40°-50°. In addition, it is also equipped with a feed port, discharge port, thermometer port, vacuum port, etc

The internal structure is simple, easy to clean and maintain, and meets GMP requirements.
Suitable for the reaction of heat-sensitive materials and oxidizable materials.
High degree of automation, easy operation, and can reduce labor intensity.
Improved efficiency and enhanced safety.
