Early in the last century eighty's, ninety's, dry granulating machine technology has done a lot of research work, to be used in dry granulation technology of ceramic production enterprise wide, many technical problems need to solve.
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.
It is understood, 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 operation process of dry granulator:
1 prepare materials, the control of indoor appropriate temperature, humidity ≤ 65. According to product requirements fineness installation screen, select the appropriate pressure.
2 boot sequence: switch on the dry granulating machine power supply, close the high circuit breaker, press the start button, start the granulating converter (left), and then start the tablet press converter (in) finally start feeding frequency converter (right) off the reverse order
3 operating frequency is first according to the panel on the RUN and then adjust the frequency setting knob to adjust the speed down is placed according to the panel on the STOP, and then the knob back to zero, the details please refer to the inverter manual.
4 to be unloaded in normal operation, the material into hopper, timely adjustment of cylinder pressure and the compressing motor feeding motor speed, so that the three factors to achieve the best combination of state. At the same time adjustable dry granulator motor speed.
A: if the sheet is too loose, pressure, or reduce the speed tablet press motor or speed up send speed motor.
B: if the sheet is too hard, can reduce the pressure, or speed up the compression speed, or reduce the sending speed motor.
C: if after the adjustment is still not pressed into the film, increase the moisture of material and spray edible alcohol adhesive.
Because and exclusion. The timely replacement of damaged. Press wheel is stuck to the surface of a material, cannot use metal tool forcibly removed, so as not to damage the roller surface. |
