If you are fortunate to have a Bosch or an H & K encapsulator, you have the world at your feet.
Tamping is the equivalent of the pre-compressing station on a modern tablet press and its
function is to create a soft more compact slug by removing the entrapped air. Imagine the ability
to make up to five tamps, all of varying strength, and then deliver this slug to the capsule with
absolute confidence that all the slugs are the same.
So how does this control work when optimized? As we see in the photograph below, we have
five different tamps all lined up and ready to use. How do we optimize this option?

Notice that there are five separate tamping stations in sets of three facing us. The trick to better understanding how to
operate the system is to think of the tamping system as a series of escalating steps to the second floor. As you go from step
one to step five it becomes a little harder with each step to go up farther. With the tamping step, each time we squeeze the
material, it becomes harder for it to return to its initial state. And that is the beauty of this system: we have five tamps of
varying severity. That is technically 25 different positions to optimize the slug preparation step.
So how should we proceed? You begin by backing all five tamping stations off so there is no tamp at all. If you cannot obtain
target fill, you begin by using a moderate tamp at station one. If this does not work, try two moderate tamps at stations 1 and
3. You might also use stations 1 and 2. At this point if you have not reached target fill you try three consecutive tamps. So
companies use moderate tamps at stations 1,3 and 5 so that there is a brief rest period during which the material may
equilibrate and prepare for the next hit.
In extreme cases you may wish to try other combinations, such as a hard/soft/hard combination for herbals. Note that it is
very rare for one to use the hardest tamp possible at all five tamping stations.
Good Luck!
