Use characteristics and operation requirements of double conical revolving vacuum dryer
Aug 07, 2018

The double conical revolving vacuum dryer is a drying device that integrates vacuum and mixing during the operation. The equipment is effectively dried in the vacuum drying process, and the vacuumed system is used to vacuum the vacuum. At the same time, the material to be dried is continuously heated, so that the moisture inside the material diffuses to the surface through the pressure difference or concentration difference, and the water molecules (or other non-condensable gases) obtain sufficient kinetic energy on the surface of the material to overcome the mutual attraction between the molecules. It diffuses into the low pressure space of the vacuum chamber and is pumped away by the vacuum pump to complete the separation from the solid.

The use characteristics of double conical revolving vacuum dryer

1. During the vacuum drying process of the double cone rotary vacuum dryer, the pressure inside 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, so that the medicine which is easy to oxidize can be dried, and the material is reduced. The chance of getting bacteria.

2. Double cone rotary vacuum drying machine because the moisture content is proportional to the steam pressure during vaporization, so

When vacuum drying, the moisture content in the material can be vaporized at low temperature to achieve low temperature drying, which is especially suitable for the production of drugs with heat sensitive materials.

3. Double-cone rotary vacuum dryer can eliminate the surface hardening phenomenon caused by atmospheric hot air drying to a certain extent, mainly because the pressure difference between the vacuum drying material and the surface is large, and the water is quickly under the pressure gradient. Move to the surface without surface hardening.
