In the western medicine pharmaceutical process, granulator is playing an indispensable role. With the continuous development of pharmaceutical market, the pharmaceutical industry expectations and requirements are also getting higher and higher, granulating machine want to have a better development in the future must change with the market constantly push pin out new.
Granulator fast, good effect, filter design special hole, careful screening, the friction filter rod can crushing sieving solid particle, is widely used in pharmaceutical, chemical, food industry. And it can substitute for swing granulator, is a new generation of particle equipment. It is a rotating cylinder with a swing function, through the wire sieve can research into the wet powder material particles, can be widely used as grinding has become pieces and become used ready-made particles, as a wet alloy powder grinding into particles in the chemical aspects, after drying for pressing tablet, and crushing during storage and clot or caking in chemical process industries in pieces.
The 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, especially for the granulation in wet heat easily decomposed failure or caking material. Dry granulating machine made of particles can be directly tabletting or filling capsules.
Dry granulating machine using the latest rolling control technology, control equipment, the equipment can adjust different materials and the volatility of any physical properties of the same material between different group, the process parameters of dry granulation can be accurate, repeated adjustment, so as to efficiently produce high quality particles. Dry granulation technology by roller press granulating machine. With traditional Chinese medicine the relative density of extract, the spray drying to obtain dry extract powder, add some accessories, to squeeze dry granulating machine pressed into thin slices, and then crushed into particles. The method needs less materials, is helpful to improve the stability of the particles, disintegration and soluble powder.
Future, dry granulating machine will meet the clean and flexible functional requirements. First of all, as the dry granulating system is completely closed, can reduce the dust pollution in the production process, thereby reducing the risk of pollution and pollution; secondly, the equipment adopts a modular design, the granulating device can only use a small amount of tools can be disassembled, convenient for cleaning of all the modules, and can be easily replaced screw and a pressure roller which adapt to different tasks.
The application of new technology can greatly improve the granulation, granule of Chinese medicine preparation efficiency and product quality, so the development process in the granulator after should focus on technology innovation, clean and flexible to meet the requirements of the industry.
Development and promotion of successful small dry granulator, finally let processing particles into thousands of households. Dry granulating machine does not need steam and special workshops, small investment. The production capacity is particularly small feed mill, feed piglet pellet feed distributor and large-scale pig farm use.
Dry granulating machine faults
Dry granulator granulation without boiler, belonging to the cold, therefore has the following several aspects of the problem, affect its application. At present, only suitable for production of granular material by adding water, rabbit.
Particles forming poor: no steam conditioning and starch, granule forming dry granulation rate is low, high rate of powder. Some special stages, such as high-grade feed and pig pellets, add a high content of sugar, difficult to molding. Need to add extra water to assist, serious impact on grain quality.
Grain hardness: the grain moisture content dry granulating in 10% ~ 12%, grain hardness than steam granulation, the palatability of feed intake of pigs and the negative effect.
Ripening degree low: dry granulating no boiler steam temperature of 70 degree, only short 60 ~ in the extrusion process of friction, which belongs to cold granulation, affect the digestibility in pigs.
The production efficiency is low: because of poor shape, the equipment power low, dry granulating production efficiency is much lower than the steam granulation.
Dry granulating machine equipment less: because unprofitable, dry granulation often lack the equipment: cooler, grading sieve, transmitting system, affect the efficiency of production and processing. |
