Gericke extended their range of high quality material handling equipment. The packaged vacuum system is designed for to easy conveying of powdered and granular products for the food and pharmaceutical industry with very fast strip and clean facility. Incorporated standard features allow the equipment to handle many non free flowing powders:

• large area reverse jet filters, steep angle cones, large diameter outlet valves and easily added discharge aids
• throughputs at 100 kg/h up to 4,000 kg/h, horizontal conveying distances up to 50 m, vertical distances up to 20 m

Typical applications are:
• mixer loading/unloading, gravimetric/volumetric feeder
• re-fill, filling machine loading
• silo to process transfer
• big bag unloading etc.

Low velocity transfer enables many mixtures to be vacuum conveyed without demixing, fluidisable powders can be conveyed at very high throughputs with very low power consumption (very large energy saving by reducing power consumption).
All packaged systems comprise 3 main items:

1) Pick up bin and suction lance: to condition and aerate the product prior to transfer
2) Vacuum receiver: key item, receives the conveyed product and separates it from the conveying air by utilising a compact reverse jet filter (cleaned automatically), designed with a very steep angled outlet cone to ensure full discharge of most non free flowing powders. The outlet of the hopper is complete with an air operated butterfly valve which ensures leak free holding of fine powders until discharge is requested. The whole assembly is high quality stainless steel with easily dismantled modular construction.

3) Vacuum pump: provides the motive conveying air, is chosen from any of 3 types to suit the application. The 3 main types are:
a) side channel or re gen units (used for medium vacuum levels and distances up to 30 m)
b) sliding vane or claw pumps (produce very high vacuums for dense phase conveying or long distance systems)
c) rootes or positive displacement pumps (used on the higher throughput applications with moderate to high vacuum requirement)

All items can be integrated into a quickly assembled package giving maximum flexibility. Several units are running very well on products varying from calcium carbonate to oats to raisins to sugar. On a large full scale test plant the clients products can be tested and verification on minimum degradation can be assessed.
