Description

The standard FIA Chewing Apparatus DRT has a fixed operation for the masticating jaw´s movements. The linear movements Press and Open are achieved by a pneumatic cylinder that is forced to reach the end positions of the cylinder. In a similar way the twist motion must always reach the end position (Twist). (The positions of the twist cylinder are Twist and Regain, where only Twist is acting on the chewing gum by torque forces). The PTM module enables the ability to register pressure and torque forces during the mastication of chewing gums. There is also the possibility to set a maximum pressure value before the chewing sequence proceed with the twist movement.

A PTM module can optionally be added to the apparatus which enable both pressure control with monitoring and torque monitoring.

If the maximum value is reached for the pressure on the gum, the twisting movement of the jaws is achieved even if the end position of the Press-movement is not reached. With a hard gum, the gap between the jaws must not necessarily be reached before Twist motion is applied on the gum.

The PTM module must be ordered for various amount of chewing cells during purchase of a new Chewing Apparatus. It can’t be retrofitted.
