Double cone rotary vacuum dryer is used more widely raw material medicine production equipment, this is because in the process of vacuum drying, the cylinder pressure is always lower than the atmospheric pressure, less number of gas molecules, low density, low oxygen content, which can dry and easy oxidation changes of drug production, can reduce the material contamination opportunity. Because the water in the vaporization process, the temperature and pressure of the steam is directly proportional to the vacuum drying, the moisture in material can at low temperature vaporization, achieve low-temperature drying, especially suitable for heat sensitive materials in pharmaceutical production. At the same time, vacuum drying can eliminate atmospheric hot air drying and easy to produce surface hardening phenomenon, this is between material vacuum drying and surface pressure, the pressure gradient effect, water quickly move to the surface, no surface hardening. In addition, vacuum drying, the material between the internal and external temperature gradient is small, the reverse osmosis the solvent alone could move and collection, overcome the phenomenon of hot air drying solvent separated from.
From the functional perspective, double cone rotary vacuum dryer is a set of drying equipment, mixing, vacuum drying in one of its people, as the classical equipment application is simple, convenient and double features, it has a practical and economic, is difficult to substitute other equipment.
Dry granulating machine is the second generation of granulation method "one step granulating" developed a new method for granulating, pelleting process is a environmental protection type, directly to the new equipment powder pressed into a pellet. Dry granulator granulation, widely used in pharmaceutical, food and chemical industries, is particularly applicable to the case
The material heat easily decomposed failure or caking wet granulation. Dry granulating machine made of particles can be directly tabletting or filling capsules.
Pigment special belt drier is through continuous drying equipment, air permeability, good for sheet strip, dry granular materials for water, dehydrated vegetables, herbs such as rate is high, and the temperature does not allow high material is particularly appropriate; the dryer has a series of advantages of fast drying, evaporation intensity is high, the quality of the products well, for paste materials of dehydrated cake shaped, and can be made into rod-shaped granulating or can be dried after. |
