Automatic powder dosing machines for pharmaceutical industry
This is why Tecnotrend suggests for pharmaceutical injectable powders their vacuum/pressure system without dosing disk to minimize parts friction, even though the vacuum / pressure dosing system with rotating disk is the most common way to dose pharmaceutical powders all over the world.
To reduce parts friction, Tecno Trend has designed its own dosing group by minimizing the number of parts which compose the group itself. The fewer parts are mounted on a dosing unit, the greater the guaranteed cleanness. And this is a basic concept of sterility.
Also Tecno Trend has concentrated in designing the parts in contact with the product as well as any other part on the machine working deck without “dead legs” or critical spots where dirt can collect. And this is another way to boost machine cleanness.
Last but not least, an ideal sterile packaging machine must move the product as little as possible.
So Tecnotrend designed and patented in 1993 a particular composed planetary kinematic chain that minimizes the excessive strokes and the high accelerations transforming all the complex sequence of the dosing needles movement into a gentle continuous movement with constant speed.
Tecnotrend applied vacuum/pressure dosing system without the disk, realizing a series of microdosing machines for injectable powders, purposely designed to work in sterile environments.
