HECHT‘s SE-RVS is a sack discharging station in hygienic design with integrated vibrating sieve for dissolution of small lumps and separation of contaminants. The integrated protective vibrating sieve holds back all impurities that must not get in touch with the product or that exceed a defined particle size (protective sieve). Furthermore, small lumps can easily be dissolved. Because of the internal vibration decoupling, no hygienically critical transition sleeves are needed (one-piece casing). If necessary for product changes, the sieve can be exchanged without using any kinds of tools. Due to the round design, the SE-RVS can easily be cleaned and is suitable for the use in Ex-zones. A ventilator behind the external filter generates a continuous low pressure in the system in order to avoid the emission of dust while discharging the sack. The suction can be switched on automatically when opening the front flap.
