PLEASE NOTE THAT WE NOW HAVE A MIX CALCULATOR IN OUR MEMBERS AREA WHICH IS FREE OF CHARGE FOR ANYBODY TO USE
Okay, so we're back at my mixing table and the first thing that we have to do is we have to get an average weight of our tablet that just contains the pill binder. We're going to leave it at 20. The more tablets you do, the more accurate average you get, but 10 to 20 is more than enough for just a small round of production. If you were going to be doing millions and millions then I would definitely suggest doing up a thousand so you can get a really accurate average. But for the TDP or something that you're doing in your home, it's more than adequate to just do up 10 or 20.
Okay, so we've just weighed out our tablets and they weighed out at 11.7 grams. So our binding tablets, or tablet B, work out at 11.7 grams. So what we need to do is we need to get an average weight for the 20 tablets. So we divide by 20. That equals an average tablet weight of 0.585. The next thing we need to do is calculate the average tablet weight of our active ingredient.
Okay, so we're back over at our TDP 5 pill press and today I'm going to be making sugar tablets using brown crystalline sugar to represent a crystalline active ingredient. You could also use a powdered active ingredient like caffeine powder or vitamin C or vitamin D, but a lot of my customers tend to ask me about crystalline substances so I thought I'd make this video using that. I've added a couple of spoons into the top of the shoot and what we're going to do is we're going to hand crank out between 10 or 20 tablets so that we can get an average weight of the tablet of pure active ingredient. Now, the reason why we're not going to use the motor to do this is because we don't know how the active ingredient will react in the dye. Whereas we know that the microcrystalline cellulose will compact, we can't guarantee that with something like brown sugar.
So to avoid damage to the TDP 5, we're going to hand crank out each of the 10 and we're also not going to worry about whether or not the tablet falls apart on ejection because it's got no binding agent in there so the chances are it will come out very loose or it will only just be held together. But hopefully with a slow hand held crank, we should be able to get out 10 to 20 reasonable tablets. And there we go. That's exactly what I was expecting to happen. The machine has got to a point instantly where it can't roll any further due to the fact that the brown sugar will not compact any further. So if you take the de-jamming bar and just try to push it forward. Is it going to go? No. It's definitely not going to go forward, which means we're going to have to do each tablet one by one backwards.
