The double -tales turn vacuum dryer is a double -tapered tank. In the inner vacuum state of the can, pass the steam or hot water into the jacket for heating. The water vapor was pulled away through the vacuum pump via the vacuum exhaust pipe. Because the tank is in a vacuum state and the rotation of the tank has continuously flipped the material in the inside and outside, the drying speed of the material is accelerated, the drying efficiency is improved, and the purpose of uniform drying is achieved.

The dual -cone turnthism vacuum dryer system is mainly composed of double cone to vacuum dryer, condenser, dust collector, vacuum exhaust system, heating system, cooling system, electrical control system, etc.

The design of this machine is advanced; the internal structure is simple; cleaning is easy to discharge the materials; the operation is easy; it can reduce the labor intensity and improve the working environment. At the same time, because the container itself turns back, the material is also rotated, but the wall is not accumulated on the wall; therefore, the heat transfer coefficient is high; the drying rate is large, not only saving energy; and the material is uniform and fully dry; good quality. It can be widely used in the drying of materials such as pharmaceuticals, chemicals, food, fuel, etc., and meets GMP requirements.

The working principle of double cone turning vacuum dryer

The tank of the double cone to turn the vacuum dryer is cylindrical in the middle, the ends are conical, the top of the conical top, the inlet of the outlet (as a human hole), the inside and outside of the can Steam or circulating hot water, the insulation layer is a medium alkali super fine glass wool, which consumes very little energy; the inner layer puts the material to dry the drying under vacuum conditions. The phenomenon of returning yellow on the surface when the material is dry, and the drying time of the material is greatly shortened. It is only about 2/3 of the drying time required for similar materials in the vacuum oven to increase labor productivity.

The performance characteristics of double cone back vacuum dryer
1. During the process of vacuum drying, the pressure in the cylinder is always lower than the atmospheric pressure, the number of gas molecules is small, the density is low, and the oxygen content is low. Therefore, it can dry and oxidize medicines and reduce the chance of material staining.
2. Because the temperature is proportional to the steam pressure during the vaporization process, when the vacuum is dry, the wet division in the material can be vaporized at low temperature to achieve low temperature drying. It is especially suitable for drug production with heat -sensitive materials.
3. Vacuum drying can eliminate the surface hardening phenomenon that is easily generated by normal pressure hot air drying. This is because the pressure difference between the vacuum drying materials and the surface of the surface is large. Under the pressure of the pressure gradient, the water will quickly move to the surface without surface hardening. Essence
4. Because when the vacuum is dry, the temperature gradient inside and outside the material is small. Due to the inverse penetration effect, the wet points can be moved and collected alone, which effectively overcome the dislocation of the hot air drying.

Scope of application range
It is suitable for

the concentration, mixing, drying, and low temperature and drying materials (such as biochemical products, etc.) of the pink, granular and fiber of chemical industry, pharmaceuticals, food and other industries. It is particularly suitable for the dryness of the easy oxidation and flammable, flammable, explosive materials and thermal materials; the materials that are not destructive, strictly restrict metal ions, and require discharge of volatile objects (or toxic substances) must be recycled (or destroy toxicity to toxicity (or toxicity. ) Materials can show its superiority.
