Lean phase conveying systems are the elementary solution for transfering bulk materials that do not require particle preservation and are not abrasive.
It's advantage lies in the versatility of products that can be conveyed as well as in the space saving setup.
The Gericke Rotaval range includes easy clean valves, welded and machined stainless steel bodies for Pharma and hygienic executions for nutrition.
The product is usually introduced by means of a rotary valve into the piping system. A sufficiently high gas velocity (typically >20m/s) is required to keep the particles in suspension (keep the particles "flying") and to convey the bulk solids into the receiving hopper. Gericke's airlocks and the configuration of the product intake minimises the damage of the equipment by the inavoidable leakage air.
