Tablet compression slide Gates towards the extreme.
Warning – Using 100 % slide gates in open position you are creating problem to company earlier form 483 have been issued by USFDA(United states food and drug administration) due to this problem 100 % open slide gate could make over weight tablet
Science behind slide gate
Science behind slide gate rest with when we are using 100% slide gate open we are putting all the pressure over from the overhead blender to the hopper and from the hopper to the feeder and subsequently into the die.
originally tablet presses have never been manufactured to withhold the pressure
due to this excessive amount of pressure in die overcharging of die occurs and overcharging leads to overweight tablets
Another problem
100% slide gate open leads to excessive filling of feed frame and thus the powder which is in re circulation channel does not find its way inside the feed frame and feel of the table press / compression machine and leads to yield loss
and Professionals are thinking continuously why yield loss is occurring
Solution to the problem is never use 100% open slide gates if we are doing so the pressure of the blend will not pass over to hopper instead we can open 70% slide gate in overhead bin 30% in hopper and thereby reducing the pressure in the die to minimum .
and considerably less chances of producing an overweight tablet .
