This video animation visualizes many of the ways in which K-Tron can provide food processing automation solutions for food manufacturing operations. In this fly through you'll travel from raw ingredient delivery, to weighing and batching of food ingredients, to end-product feeding and conveying for mixing and extrusion.

In order of appearance, you'll see the following processes:

  • Rail and truck unloading
  • Pneumatic conveying to silo
  • Addition of major ingredients into the process (batch weigh system)
  • Gain-in-weight batching (GIW)
  • Loss-in-weight batching (LIW) Food Industry Brochure
  • Minor ingredient addition
  • Batching of major and minor premixes
  • Continuous mixing (LIW feeding and dense phase vacuum conveying)
  • Dense phase vacuum conveying
  • Extrusion via loss-in-weight powder and liquid feeding

Smart Weigh Belt Feeders (SWB)

K-Tron's stainless steel Smart Weigh Belt (SWB) feeder serves many food applications and is the first weigh belt feeder to offer the continuous online auto tare function, enabled by a second weigh bridge.  Weigh belt feeders offer gravimetric feeding at higher feed rates in areas where low headroom is a problem.

 The Smart Weigh Belt (SWB) feeder is available in open and closed frame versions and in 300 mm and 600 mm belt widths, enabling feed rates up to 40,000 kg/hour (88,000 lb/hour). K-Tron has earned industry recognition for its proprietary digital weighing technology. Using the K-Tron Smart Force Transducer (SFT) weighing technology in combination with the K-Tron Smart Connex™ feeder control platform, K-Tron Soder feeders have demonstrated excellent performance, accuracy and return on investment in demanding food industry applications.

Aerolock Rotary Valves: K-Tron offers Aerolock rotary valves for many industries including Milling and Bakery applications.

Bag Dump Stations and Batch Weigh Receivers: Part of K-Tron's family of bins and hoppers designed to ensure a clean and sanitary environment for Food Processing applications.

Gain-in-Weight Batching: Custom Engineered Batching Solutions

K-Tron Gain-in-Weight Batching Stations are the preferred choice for flexible and economical batch preparation in applications involving up to 8 components and 100 recipe lines. Each component is sequentially and independently metered to a weigh collection hopper from which the completed batch is dischaged. Any of K-Tron's wide range of volumetric metering devices may be employed as demanded by ingredient handling characteristics.
