Cone Vacuum Dryer Working Principle

The SZG series double cone rotary vacuum dryer is a double cone rotary tank. When the tank is in a vacuum state, heat transfer oil or hot water is introduced into the jacket for heating. The heat contacts the wet material through the inner wall of the tank. The water vapor or other gas evaporated by the wet material after absorbing heat is pumped away through the vacuum exhaust pipe by the vacuum pump. Since the tank is in a vacuum state and the rotation of the tank makes the material constantly move up and down, inside and outside, the drying speed of the material is accelerated, the drying rate is improved, and the purpose of uniform drying is achieved.

Cone Vacuum Dryer Features

The double cone rotary vacuum dryer is a new type of dryer that integrates mixing and drying. The condenser, vacuum pump and dryer are matched to form a vacuum drying device. (If the solvent does not need to be recovered, the condenser can be omitted) This machine has advanced design, simple internal structure, easy cleaning, and all materials can be discharged. It is easy to operate. It can reduce labor intensity and improve the working environment. At the same time, because the material rotates when the container itself rotates, but there is no material accumulation on the wall, the heat transfer coefficient is high and the drying rate is large, which not only saves energy, but also makes the material dry evenly and fully with good quality. It can be widely used in drying in the pharmaceutical, chemical, food, dye and other industries.

Application Range

Double cone rotary vacuum dryer is suitable for vacuum drying and mixing of powder and granular materials in the pharmaceutical, food, chemical and other industries, especially for drying with the following requirements:

※Thermosensitive materials that cannot accept high temperatures

※Materials that need to recover solvents and toxic gases

※Easily oxidized and dangerous materials

※Materials that require crystallinity

※Materials that require extremely low residual volatile content

Technical Specifications

Note: For materials with large volume changes before and after drying, the loading coefficient can be appropriately increased or reduced, and the (maximum) loading volume cannot touch the bottom of the vacuum tube.

The motor can be equipped with a speed-adjustable motor according to user requirements, with a speed of 0-6rpm; the material specific gravity of the above technical parameters is calculated as 0.6g/cm3. If it exceeds, it must be stated when ordering; if the user needs a pressure vessel certificate, it must be stated when ordering; if the inner tank material is glass-lined, it must be stated when ordering; if the material is flammable and explosive, it must be clearly stated when ordering, otherwise it is strictly prohibited to use.

Ordering Instructions

※ Heating is divided into two forms: hot water heating and heat transfer oil heating.

※ When ordering, please indicate the temperature that the material can withstand or the operating temperature of the dryer so that our factory can select or provide a heat source for you.

※ When drying sticky materials, our factory will specially design a "copying plate" structure in the tank.

※ Our factory can provide and install all accessories involved in the vacuum drying system for users, please indicate in the order.

※ Our factory can provide design, manufacturing and installation for special requirements of users.
