Composition of dry granulator is mainly composed of feeding, mixing, granulating, transmission and lubrication system. Dry granulating machine working process with powder less than 15% moisture content, from the hopper into the feeding auger, by adjusting the stepless speed regulation motor speed, obtain material flow right, then into the blender, tempering the stirring rod stirred and mixed with steam, if need to add molasses or grease, also from the mixing drum added and together with the steam, oil content of less than 3%, otherwise it is difficult to form, after quenched and tempered with powder temperature can reach 64 ~ 85 ℃, relative humidity 14 ~ l 6%. And then through the chute through the iron absorption device can select the powder to remove iron impurities mixed in, and finally into the press room.
Dry granulating machine has simple and convenient operation, dry granulator intermediate improves the quality of the product, made of uniform particles, pine is suitable, the particle size distribution is narrow, round shape, good fluidity, particles can be prepared by the small color difference, the required particle. Mixing, granulation, drying are completed in one machine, simplifies the production process, reduces the labor intensity; one step granulating of high degree of automation. The operation can be carried out according to the design parameters of the production process requirements, the production of good reproducibility.
Dry granulating machine to improve the production efficiency, shorten the production cycle, improve productivity, save energy, high production efficiency.
Dry granulating machine meets the requirement of GMP, a vote expected granules made of discharging the entire process from raw materials are operating in a closed state, can effectively avoid the powder dust, to avoid cross contamination, ensure the production environment to meet the requirements of GMP.
Dry granulator is applicable to a wider range, apply to the high viscosity of the extract or the traditional Chinese medicine dry granulation powder, can be directly sprayed people extract, also can be to stem the water-based adhesive spraying powder, avoid the use of organic solvent is flammable, explosive, thereby reducing the cost; granulation and drying temperature is low, very suitable for the drug is not stable to the heat production. |
