piGENTLE automates pneumatic tablet conveying

by

Piab’s new piFLOW device uses piGENTLE technology to control the speed of automated, pneumatic conveying of delicate tablets

Jarno Tahvanainen, vice president of Piab's material handling division, said: “The secret of careful vacuum handling lies in a controlled low and constant speed as tablets are transferred from one place to another.

“piGENTLE has been specifically designed to ensure that a continuous and gentle flow of tablets is maintained throughout the entire conveying system.”

A patent application has been filed for the piGENTLE technology that regulates the feed pressure of the piFLOW pump by sensing the vacuum level in the system. As tablets fill the pipe line, the vacuum level increases, triggering an increase in feed pressure. piGENTLE  will regulate the feed pressure between 2 and 6 bar.

A low start pressure allows tablets to be picked up at low speed. The start level can be manually adjusted to suit specific products, according to their size, shape and weight.
