Dry granulator 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, dried for compressed tablets, also can crush during storage and clot or caking in chemical process industries in pieces.
With the continuous development of the industry, dry granulating machine began to cut a striking figure. It is a new method of one step granulating granulation of the second generation of granulation method developed after granulation process, is an environment-friendly, directly to the new equipment powder pressed into a pellet.
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 can be accomplished through dry granulator drum. With traditional Chinese medicine the relative density of extract, the spray drying to obtain dry extract powder, add some accessories to stem dry granulator, extrusion pressure into a sheet, and then crushed into particles. The method needs less materials, is helpful to improve the stability of the particles, disintegration and soluble powder.
Dry granulating machine has the following characteristics:
1, the constant pressure: dry granulating pressure is the key factor affecting the granulation effect. The machine has the constant pressure system, granulating effect than conventional dry granulating machine more stable, particle density, compressibility have better consistency, reproducibility.
2, low temperature granulation: granulation is under high pressure compressed into tablets, continuous generating more heat granulation process, equipment, material temperature will rise in temperature, dry granulating machine with a cooling system, the pressing process generates heat, so as to ensure the stability of the continuous production of main drugs.
3, a horizontal twin screw feeding: the machine adopts horizontal double spiral feeding, feeding more uniform.
4, the modular structure, dry granulator is modular in structure, free tools to disassemble, use more convenient.
Dry granulating machine in the future development process, technical requirements will be increasingly high, clean and flexible function will become the industry the common pursuit of goals. Pharmaceutical companies have a clear development goals, to be a sportsman forward.
Dry granulating machine is provided with a lifting mechanism, feeding device, pressing device, granulating device, hydraulic system, cooling system, dust removal device, electrical control, sieving device, vacuum conveying device (according to customer needs with) ten parts.
A: the lifting mechanism adopts electric pump lifting device, feeding device in the cleaning time.
B: feeding device: using variable frequency speed to change the feeding speedC: pressing device: the variable frequency speed to change the compression speed.
D: granulation, granulation device: to apply to different materials using different granulating cutter, to improve the rate of finished products, adopt frequency conversion to change the granulation, granulation speed.
E: hydraulic system: adopting imported hydraulic components, good pressure maintaining performance, so that the material in the process of working pressure is consistent, reduce the fault of hydraulic system.
F: cooling, using water or cooling water, heat extrusion through a rotary joint circulation cooling device cooling roller produced.
G: dust removal system: the dust removal device, effectively prevent dust.
H: electronic parts: man-machine interface control, friendly interface, intuitive operation, convenient.
The man-machine interface and PLC control system, instead of the button, the traditional relay control system, to reduce a lot of electrical components, reduce a lot of contact, connection is greatly reduced, greatly reduces the fault contact failure, greatly improve the reliability of the system, and according to user needs memory parameter content, simple and convenient operation, the system has the function of automatic detection, fault can prompt the user, convenient repair. The early warning and alarm function.
Can realize the stepless speed regulation by frequency converter, motor soft start, the inverter has various protection alarm function, can effectively protect the motor, extend the service life of the motor. The electricity saving operation.
This system can avoid the motor stall death card, in case of blockage alarm automatically reverse motor troubleshooting, high degree of automation.
I: sieving device: due to the dry granulating out a part of the fine powder, adding a sieving device can be directly will be graded out user needs particles, direct product |
