Our extensive product range includes a large number of feeding systems with screw diameters from 5 to 130 mm. From very small quantities starting at 5 g per hour up to several tons, a wide range of materials can be precisely fed. The performance of the equipment is particularly evident in the efficient feeding of poorly flowing powders. Both for gravimetric as well as the volumetric feeding, Three-Tec offers the appropriate devices incl. control system.
The sophisticated design allows assembly, disassembly and cleaning of all components in contact with the product in just a few steps and in a very short time. All components in contact with the product consist of stainless steel 1.4404 (AISI 316L) and can therefore be cleaned easily and efficiently with a wide range of liquids and solvents. Automated cleaning systems such as WIP (washing in place), CIP (cleaning in place) or SIP (sterilization in place) are available on request.
Three-Tec‘s flat-tray feeders guarantee precise volumetric and gravimetric feeding of good to poor-flowing, moist or bridging products with flowabilities of ffc 1 - 5. All flat-tray feeders can be supplemented with a scale and control system at any time and operated as a gravimetric «Loss in Weight» or «Gain in Weight» and as a continuous system, or used for batch filling.
The flat-tray feeders are equipped with easily exchangeable feeding tools. Various feeding tools such as auger, concave or spiral screws facilitate adaptation to the product to be fed.
The two feeder types ZD 5 i6000 and ZD 9 i10000 are also available with integrated load cells instead of the platform scale. The all-in-one solution makes the feeder smaller, lighter (only 5 kg) and easier to handle and thus easier to position.
Due to the low drop height, the feeder has a lower susceptibility to external disturbances such as drafts or vibration. In addition, the resolution of the load cell is considerably better due to the smaller weight of the device.
Twin and single screw feeders
Twin and single screw feeders allow precise volumetric and gravimetric feeding of well-flowing powders, granules, micro-granules, grain, pellets, chips, flakes and short fibers.
All standard feeding units can be upgraded with a scale and weighing electronics and operated as gravimetric «Loss in Weight» or as batch systems. The flat-tray feeders are equipped with easily exchangeable feeding tools. Various feeding tools such as auger, concave or spiral screws facilitate adaptation to the product to be fed. The horizontally rotating bridge breaker prevents the product from bridging and the bulk material thus flows into the feeding screws without interruption. For free-flowing bulk solids units are also available without bridge breaker.
The standard feeding units are available in a type version «Quick Clean» as volumetric or gravimetric version, which are very easy to disassemble and clean.
