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.
Vacuum Transfer into a High Shear Mixer
Vacuum conveyors can be used as a dust-tight method to transfer powder from ground floor level into a high shear mixer.
In-Line Vacuum Milling
In-line vacuum transfer through an over-driven conical mill for achieving automated, dust-tight milling (same process can be achieved with an under-driven conical mill).
In-Line Vacuum Sieving
Vacuum conveying can be used to transfer material through a sieve into a downstream process or container.
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.
Vacuum Transfer into a Vessel
Vacuum conveying can be used to transfer material from a ground-floor drum into a vessel or tank (with modifications this can be made suitable for pressurised vessels).
Unloading a Fluid Bed Dryer
Vacuum conveying can be used to transfer material from a fluid bed dryer after the drying process is complete (shown here with an optional in-line mill for improved PSD).
