Whether for installation in silos or in downpipes – the HECHT screw sampler is the ideal solution for a representative sampling of any kind of bulk material. At individually selectable time intervals, the defined amount of product is sampled either automatically or manually by means of a hand wheel. A pre-installed self-cleaning function guarantees the validity of the samples. Depending on our customers’ requirements, we offer various connections for matching sample vessels as well as different sealing valves. Installation in silos or downpipes possible Different diameters for screw samplers available Sample quantities, runtimes and pause times individually adjustable Automated or manual sampling method Easy-to-dismantle version for simple cleaning The sampling screw rotates into the material flow, extracts a representative cross-section from the production flow and transports it into a sample vessel. An adjustable timer determines the sample quantity. Runtimes and pause times between two sampling operations are individually configurable. Before starting a further sampling process, the screw changes to reverse operation for a self-cleaning cycle. The product conveyed during the self-cleaning process is fed back into the production flow. Different systems like stuffing boxes / gland seals or a shaft ring seal ensure a final sealing. To guarantee a considerate and gentle product handling, it is recommended to install a counter-bearing.
