FDA Approved Valves Assist with Food Bagging Application

A specialist designer, manufacturer and installer of powder handling systems, powder conveying systems and equipment, pneumatic and mechanical conveying systems and equipment, have been installing AKO Pinch Valves into their equipment and machinery for 9 years.

The industries the company serve include bakery and confectionary, cereal, dairy, animal feeds, pharmaceutical, chemical and mineral. This particular application is a Big-Bag filling and Big-Bag discharging process.

A high speed batch weighing and vacuum conveying system controls four separate ingredients at varying quantities, for over 60 different recipes.

Valves for Bag Filling Application Process & Performance

Each Pinch Valve handles an individual big bag discharger and batch weighing assembly, delivering weighed quantities directly into the vacuum conveying line simultaneously, highly accurately and very fast.

A Suction Probe vacuum conveyor allows both abrasive and non-abrasive product to be delivered to a main conveying line without the need for a rotary valve.

Pinch Valve used within this application – VF100.02X.35.30LA

VF model, air operated, aluminium body, aluminium PN10/16 flanges with stainless steel bushings, natural rubber white food quality sleeve (FDA approved).

The Pinch Valves for bag filling from AKO’s VF range are regulated using a pressure gauge, and kept normally closed at just over 2 BAR. The silos contain different food ingredients including sugar and flour, that are transported down a main diverter conveying line, feeding off to the left and right where they meet a Pinch Valve. The food ingredients are held here until they are ready to be bagged up into sacks using a filling system.

Key Advantages of the Pinch Valve for Bag Filling

Along with the food quality rubber sleeve inside the Pinch Valve, the stainless steel bushings on the flanges are the wetted parts. Therefore, the food media passing through the valve for bag filling does not come into contact with the aluminium body or flanges.

The VF Pinch Valve model is a lightweight valve option, compared to some of the very heavy cast iron models that are on the market.

The internal rubber sleeve opens and closes in the same elliptical position every time, ensuring a longer service life.

Pinch Valves are characterised by a free flow of product, guaranteed because of the nominal passage of practically all diameters. They boast minimum frictional resistance and non-clogging features. The easy installation of AKO Pinch Valves for bag filling is something that is appreciated by our customers.
