Our dense phase conveying systems with pressure vessels are designed for processes that require gentle conveying, low segregation, low wear, low air and energy consumption. Another advantage when using a dense phase conveying system with pressure vessels rather than a lean phase conveying systems with rotary valves is that no part rotates in the product stream. In lean phase conveying systems, the rotating rotary valve will cause fine metallic attrition when coming in contact with the housing and thereby contaminate the product. Another disadvantage is air leakage. This occurs because of the gap between the rotor and the housing. Due to wear on the rotary valves, the gap gets bigger which leads to increased leakage of air, reduced capacity, to conveying problems and pipe blockages.

We designed the dense phase conveying system mini-double vessel PTAD20 to replace rotary valves in existing conveying plants. The Gericke dense phase conveying system mini-double vessel PTAD20 has the advantages of a plug conveying system. The space-saving execution allows the installation heights of 750 mm. The system consists of two 20 l pressure vessels which guarantee continuous operation. They are delivered with a common inlet tube or they are directly connected to the upstream process. Depending on the tube diameter (DN65–DN100) and on the product to be conveyed, capacities of 4–10 m3/h are achieved.

Several systems of this type are successfully in operation in the food industry to convey products such as milk powder, whey powder, gelatine, granules and premixes. The dense phase conveying system mini-double vessel PTAD20 is also well suited for the gentle conveying of granulates.

In the Gericke Test Centers all kinds of pneumatic conveying techniques can be tested to determine the conveying parameters. Knowledge concerning product quality (attrition) and roduct build-up in pipes can be acquired. Furthermore, Gericke offers rental units to be used on site.
