The Hanningfield Uni-Vac vacuum conveyors are designed as a safe and convenient method for transferring powder. The system utilises a combination of vacuum and air (known as ‘Lean-Phase’ or ‘Dilute-Phase’) to transport powders, granules and other material. The dust-tight sealed system prevents material contamination during the transfer process, while protecting the operator, process and environment from product exposure or accidental spillage (thereby minimising waste).
The Uni-Vac hygienic ‘V-Series’ of vacuum conveyors (V05, V10, V20, V30, V50, V100) consists of a rolled and seam welded hopper body, which can be customised to suit any requirement. All units are assembled using clamps for fast and easy dismantling for cleaning. The crevice-free, GMP design makes it ideal for demanding applications in the pharmaceutical, food and allied industries where product integrity is vital.
The Uni-Vac is able to satisfy numerous applications including; ‘suck-and-dump’ and direct loading. The Uni-Vac can also be modified with optional upgrade features including level control, line clearance valves, CIP / WIP, HEPA filters, support frames and ATEX execution where applicable. All equipment can be supplied with full validation documentation (FS/DS, FAT, SAT, IQ/OQ) and 3.1 mill certificates to EN10204.
Vacuum Transfer from Drum to Process Machine
The vacuum conveyor sucks material from the ground floor drum and up into the Uni-Vac hopper. Once full, the outlet valve opens and discharges the material into the machine.
Direct Loading (into Blender)
Where the receiving vessel is vacuum rated, material can be directly loaded by pulling a vacuum on the blender, with a filter hopper before the pump.
