Coperion K-Tron offers the widest range of feeding solutions in the industry and a variety of configurations, which can be combined to create an optimal solution for any application. This includes screw feeders, vibratory feeders, bulk solids pumps, weigh belts, liquid feeders and flow meters. Highly accurate gravimetric feeders are particularly helpful when feeding difficult bulk materials, such as plant protein powders used in the production of alternative meats. Thanks to a weight signal, they measure exactly how much bulk material is being fed into the process and as a result they can quickly react to fluctuations in mass flow caused by changes in bulk density or flow disturbances; in addition, their feeding performance is precisely documented.

Liquid feeders use the principle of loss-in-weight measurement. A liquid tank mounted on a weigh scale measures the mass flow of an ingredient into the process. Liquid materials are usually transferred into the extruder using a pump with a variable speed drive. A controller changes the pump speed or stroke to adjust the fluid flow rate to match the setpoint. Highly reliable feeding and refill systems prevent feeding inaccuracies that could cause shutdown of the entire extrusion line which, in turn, adds to process time and calls for cleaning.

Vibratory feeders are ideal where uniform discharge of very free flowing bulk materials is critical, especially at very low rates. A vibratory drive gently moves the bulk material down the feed tray to the discharge. The Coperion K-Tron K3 line of vibratory feeders features improved high accuracy thanks to innovative patent-pending drive technology. The K3 vibratory feeders have a modular design and are available in both standard and hygienic easy clean execution. Vibratory feeders are ideal for gentle handling of a wide range of bulk solid materials, especially fragile ingredients and problem materials such as finished friable food products and ingredients, flakes and fibers.
