Dry granulating method compared with the traditional wet granulation, the powder material made of granular products directly meet user requirements, without any intermediate and additive, granulating uniform product size, bulk density increased significantly, not only to control pollution, but also reduce the powder material and energy costs, improve the apperance and liquidity, easy storage and transportation, can control the solubility, porosity and specific surface area and so many advantages, especially suitable for wet mixing and granulating, step boiling granulating can not work materials.
Dry granulating machine uses dry granulating machine is the second generation of granulation method "one-step granulation" after the development of a new granulation method, is an environmental protection type granulating process, directly to the new equipment of powder pressing into particle. Dry granulator granulation, widely used in food, pharmaceutical chemical industry, especially for granulation to wet heat easily decomposed failure or caking material.
Production of dry granulator dried stem section from the top of granulator is added, the pressure into a sheet mill, in the double roll machine extrusion, material into a sheet, the sheet material after crushing, whole grain, powder screening process, get granular product needs.
Material by mechanical compression molding. Do not destroy the chemical properties of the material, decrease the effective content of product. The whole process is closed, no impurities flow, high product purity, and no pollution to environment. The production process automation, suitable for mass production.
In addition to extrusion friction can cause dangerous explosion, the unit can be directly granulated powder material of most. Through the rotary joint for water on the roll, this machine can also be suited for granulation of heat sensitive materials.
Dry granulating machine characteristics
1, the vacuum automatic feeding, automatic operation of the whole process of closed.
2, all parts in contact with drugs are rapidly disassembled, cleaned separately.
3, the eccentric structure pressure wheel side by computer control, make sheet hardness, thickness uniformity control.
4, double star wheel mesh size, so that the fine powder is reduced to the minimum.
5, adapt to the majority of Chinese medicine granule particles |
