Ruian City, Fu Rui Si import and export and we introduce the principle of tablet.
Dose control. All kinds of tablets have different dose requirements, large dose adjustment is achieved by choosing different diameter of punch die, such as 6mm, 8mm, 11.5mm in diameter and 12mm punch. After choosing the die size, small dose adjustment is by adjusting the depth of the hole into the die down, thus changing the actual length in the die hole sealing after the adjustment of filling volume of die hole in medicine. Therefore, should have the original position adjustment undershoot in the mold hole the mechanism in the tablet machine, in order to meet the requirements of dose adjustment. Because of different batches of prepared powder total volume difference, this regulation is very necessary.
In the dose control, operation principle of feeder also have a considerable impact, such as drug particles by self weight, free fall into the die hole when the filling situation is relatively loose. If the multiple forced entry mode is adopted, the mold hole will be filled with more drugs, and the filling is more dense.
Control of tablet thickness and compaction degree. The dosage of the drug is determined according to the prescription and pharmacopoeia, and can not be changed. In order to storage, preservation and disintegration, compression of a certain dose of pressure is also required, it will also affect the actual thickness and appearance of tablets. Pressure regulation is essential in the compression of a tablet. This is achieved by adjusting downward in the mold hole on the. Some press during the tabletting process not only on the downward movements, but also has the upward movement by the undershoot undershoot, relative motion to complete the tabletting process. But more is by adjusting the pressure regulation on the amount of downlink mechanism to realize the pressure regulation and control.
