Sack Handling
Powder Transfer System (MPTS) draws a reproducible and GMP compliant sample directly from the PTS Feeder into a customised sample bottle.
Safety barriers
Numerous safety barriers have been provided with the risk analysis to prevent product contamination and ensure absolute integrity of the system even in degraded operation mode. In the event of the failure of one barrier, there are still additional barriers which maintain the required security to prevent contamination. The equipment is suitable for CIP and explosion protection zone 1/21. The control is exclusively pneumatic and can remain close to the system.
Depending on the application, this concept can be adapted to
Sew it up
Sewing remains ideal to close bags of all kinds of material: cotton, jute, burlap, polyethylene, paper, woven polypropylene... Fischbein introduces the Twin Needle Sewing Head and Systems.
Twin needle sewing head
The Twin Needle Sewing Head closes a bag by sewing 2 parallel lines on it. The stitches between the two lines are offset to further minimise/eliminate sifting of product through the sewn closure. This “low vibration” Sewing Head is used for plain sewing, double stitch type 401, of open mouth bags.
Twin needle sewing system
This Twin Needle Sewing Head is installed on a single leg pedestal to build a sewing system to close paper and woven polypropylene (WPP) bags. This Twin Needle Sewing System must of course hold four thread cones and must have routing for all four threads to the twin needle Head: two threads for the needles, two for the loopers. Until now, Fischbein has produced industrial systems with twin needle Heads installed on a pedestal only for manual operations, the bag being introduced by hand by the operator. The sewing process starts when the feeler switch is activated. At the end, the pneumatic chain pusher pushes the thread chains into the knives to cut them! To have a smooth operation of the system, a conveyor is required.

suit a multitude of individual circumstances, with the different pressure levels of the system being adapted according to the priority (GMP, product or personal protection).
The handling of APIs according to GMP guidelines is always a challenge. A cleanroom to protect the product and an isolator system to protect the operator and the environment require high investment, but this concept allows a simple, compact and cost effective alternative.
Through the “open” space and the natural air circulation the use of nitrogen in the operating environment is no longer a danger whilst product contamination and exposure of the operator to dust is prevented at all times.
