Liquid Loss-In-Weight Feeder in New Modular Design

Accurate Liquid Dispensing to Food Processes

The Coperion K-Tron line of modular liquid loss-in-weight feeders provide accurate continuous volumetric or gravimetric flow control of liquids, aromas and/or flavors. The highly accurate gravimetric units combine the pump and tank with a suspension scale or platform scale, with the feed pump for metering the material located outside the scale area.

When feeding liquids, the special requirements of each application vary widely. Thanks to the new modular design of the Coperion K-Tron Loss-in-Weight Liquid Feeders, a broad range of pumps and tanks can easily be combined to constitute a reliable liquid feeding system representing the ideal configuration for the specific application. Although each liquid feeder is custom designed to meet the desired feed rate, the process demands, and the characteristics of the liquid, the new modular concept streamlines the layout and engineering process of a feeder, thus reducing its lead time and initial cost. The new modularity also provides benefits in terms of a uniform mechanical construction as well as identical operation and maintenance for multiple differently sized units. This simplifies feeder operation, maintenance and spares inventory which in turn saves effort and cost. Some of the key features are: Gear, membrane or other pump (depending on the liquid), highly accurate SFT weighing technology, liquid tanks starting from 7.5 liters, and ATEX configurations.

In addition, options are available to the modular design which include jacketed tanks for heating, as well as additional agitators dependent upon material properties and viscosities. The Coperion K-Tron line of liquid loss-in-weight feeders is ideal for high accuracy liquid addition to continuous food processes such as extrusion or blending. In addition, dispensing high value liquid food ingredients such as flavors or food additives are ideal applications due to resultant ingredient cost savings from a higher accuracy ingredient addition.
