Nucleic acid double cone rotary vacuum dryer

working principle

Nucleic acid double cone rotary vacuum dryer‍For a double conical rotating tank, steam or hot water is introduced into the jacket for heating under vacuum inside the tank. The heat comes into contact with the wet material through the inner wall of the tank, and the water vapor evaporated by the wet material after absorbing heat is extracted by a vacuum pump through a vacuum exhaust pipe. Due to the vacuum state inside the tank and the continuous flipping of the material inside and outside by the rotation of the tank, the drying speed of the material is accelerated, the drying efficiency is improved, and the goal of uniform drying is achieved. The double cone rotary vacuum dryer system mainly consists of a double cone rotary vacuum dryer, condenser, dust collector, vacuum pumping system, heating system, cooling system, electronic control system, etc.

Product Features

(1) During the vacuum drying process, the pressure inside the cylinder is always lower than atmospheric pressure, resulting in fewer gas molecules, lower density, and lower oxygen content. Therefore, it can dry easily oxidized drugs and reduce the chance of material contamination.

(2) Due to the direct proportionality between temperature and vapor pressure during the vaporization process, the moisture content in the material can vaporize at low temperatures during vacuum drying, achieving low-temperature drying, which is particularly suitable for the production of drugs with heat sensitive materials.

(3) Vacuum drying can eliminate the surface hardening phenomenon that is prone to occur during atmospheric hot air drying. This is because there is a large pressure difference between the inside and surface of the vacuum dried material, and under the pressure gradient, moisture quickly moves towards the surface, without surface hardening.

(4) Due to the small temperature gradient between the inside and outside of the material during vacuum drying, the moisture can move and collect independently due to the reverse osmosis effect, effectively overcoming the phenomenon of separation caused by hot air drying.

Adapt to materials

Double cone rotary vacuum dryerWidely used in industries such as pharmaceuticals, chemicals, and food, suitable for drying chemical products, powders, granules, and block materials.

Thermally sensitive materials: Due to the fact that the double cone rotary vacuum dryer operates in a vacuum environment and can dry at lower temperatures, it is suitable for thermosensitive materials that cannot withstand high temperatures.

Easy to oxidize materials: Due to the vacuum environment, oxygen can be isolated, reducing the contact between materials and oxygen, suitable for materials that are prone to oxidation or hazardous.

Solvent recovery: During the drying process, solvents can be extracted by vacuum to achieve solvent recovery and utilization, which is suitable for materials that require solvent and toxic gas recovery.

Materials with low residual volatile matter requirements: Suitable for materials with extremely low residual volatile matter content requirements.

Uniformly mixed materials: suitable for materials that require thorough and uniform mixing.
