HIGHLIGHTS OF OUR FEEDING SYSTEMS Efficient feeding Various solutions Quick assembly and disassembly Dismantling of the feeding screws Customer requirements A wide range of throughputs even of poorly flowing materials uncomplicated without tools for gravimetric and volumetric feeding are implemented during development and production of all components in contact with the product Smallest quantities from 5 g per hour up to several tons APPLICATION AREAS Feeding systems > Minerals & mineral substances > Feeding to tablet presses > Multiple feeding systems > Batch filling or continuous feeding >...

FLAT-TRAY FEEDERS TWIN AND SINGLE SCREW FEEDERS 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. 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....

OPTIONS At Three-Tec you can put together your feeding system according to your needs. You can choose from various controls, drives and scales. In order to configure the feeding system perfectly for the respective process, ThreeTec offers a wide variety of options: Control system More options Outlet pipe Depending on the application and process requirements, vertical or horizontal discharge tubes can be mounted. The connection to customer systems can be adapted and prepared. Bellows In order to avoid interference with gravimetric systems due to dust protection, bellows are as flexible connections....

HIGHLIGHTS OF OUR EXTRUDERS Screw diameter Quick assembly and disassembly Easy cleaning Temperature gradients Low active ingredient requirement different screw diameters (5 to 100 mm) and L/D ratios (15:1 to 60:1) available Steep temperature gradients between segments are possible due to deep cuts in the barrel Tri-clamp and bayonet connections enable a higher sample throughput Due to their small size and light weight, the mini extruders are easy to transport designed for easy cleaning and simple cleaning validation Mini-extruders with low active ingredient requirements enable smallest approaches...

LABORATORY EXTRUDERS Multifunction extrusion from small quantities to production scale for research and development as well as production applications. Extrusion results are optimally suited for upscaling or downscaling. The extruders perform complex extrusion tasks under difficult conditions such as high pressure, high torque or steep temperature gradients. The extruders are equipped with easily exchangeable tools, which are individually structured and adapted to the extrusion task by different segments such as conveying, return conveying, kneading or mixing segments. The temperature profiles...

OPTIONS AND ACCESSORIES Barrels Screw diameter from 5 to 100 mm The extruder barrels are manufactured entirely in-house at our site in Seon. Customer requirements can thus be taken into account flexibly and easily. The extruder screws are configured customer-specifically based on the process task and manufactured in-house Three-Tec offers the following types of screws: Advantages of Three-Tec extruder barrels: > Monobloc screws (demanding screw geometries, made from one piece) > Standard screws (made from one piece) > Modular screws (interchangeable screw segments) > Configuration completely...

Pelletizer The pelletizer can be used to process strands into pellets or granules. The speed of the feed roller and the cutter are independently adjustable. This allows the extrudate feed to be perfectly matched to the extrudate and the pellet length or pellet size to be adjusted between 0.5 and 10 mm during processing. Research & Development Hot cutter With the hot cutter, the extrudate can be reliably processed into pellets or granules with one or more knives in direct contact with the die plate. Both wet and melt extrudates can be processed. The number of knives used and the speed setting...

Conveyor belt laboratory Film roller The film roller from Three-Tec enables the calibration of flat, dry extrudates. Furthermore, round extrudates can also be rolled into a film with a defined thickness. Subsequently, the product is evenly wound onto a spool. The film roll consists of an adjustable and temperature-controlled pair of rolls, an adjustable pair of tension rolls and a rewinder, or spool. The conveyor belt is suitable for gentle removal and cooling of the extrudate. In order to achieve more efficient cooling of the extrudate, a cooling tank can optionally be integrated on which the...

Stuffing feeding device Stuffing feeding devices are used for the reliable feeding of very poorly feedable or very cohesive and very light products into an extruder. With the stuffing feeding device, products are pressed into the barrel of the extruder from above. Side feeding device Side feeding devices are used for the forced feeding of powders and granules into an extruder. Three-Tec manufactures side feeding devices for all extruder sizes and throughput ranges. Special machinery Three-Tec develops and manufactures a wide variety of special machinery according to customer requirements. Thanks...
