Coffee Industry

Thayer Scale is helping our customers in the coffee processing industry meet evolving municipal building code requirements and trends toward aesthetic facility designs. To achieve this, we provide automated weighing solutions that reduce processing stack up height without compromising food safety and accuracy tolerances of coffee bean blending systems.

Until recently, green bean blending consisted of gravity batch systems that required process-specific facility designs to accommodate the high stack-up height of storage hoppers and discharge chutes. Today, manufacturers typically lease space from third party management groups designed to be easily repurposed to meet the needs of future clients.

High accuracy delivery of green bean blends in a low profile stack-up that readily fits within today’s building designs is achieved with Thayer Scale weigh belts. The weigh belts eliminate gravity chute work and product free fall height to decrease product damage significantly. Gentle product handling maintains a higher bean quality and generates larger yields for the producer.

Thayer Scale weigh belts make the process easier to manage with fewer operators by automating the weighing process, seamlessly integrating with modern roasting profile software, facilitating automatic, real-time adjustments that mitigate green bean characteristic variances.

Using the weigh belts to deliver a wide range of batch sizes accurately allows processors to respond to rapidly changing customer needs and develop more customized product SKUs for their clients.

Thayer Scale weigh belts also play a vital supply chain role in green bean receiving, storage, and cleaning systems. Here, the weigh belts accurately determine the net amount of useable product from incoming bulk weights, which are often inclusive of waste stream materials such as jute bag strands, twigs, and other matter.

Weighing equipment for the coffee industry includes:

Weigh belts

  • Highly-accurate for reliable, repeatable measurements and flow rate control
  • Easily-configured for open- or closed-flow channel construction
  • Engineered to fit new or existing process flow streams
  • Easy-to-clean cantilevered frames permit quick disassembly and assembly

Loss-in-weight feeders

  • Single- or twin-screw
  • Vibratory pan or rotary feeder
  • Feed rates from grams/minute to tons/hour

Flexible conveyor belt scale designs that support multiple conveyor configurations

Hopper and silo material flow promotion solutions

  • Designed to ensure consistent, uninterrupted material flow

Modern Process Equipment selected Thayer Scale’s weigh belts for use in a fully automated coffee roasting plant. The high accuracy of the weigh belts located under the storage silos measures the green coffee beans contiguously as they are dispensed, ensuring efficient operation and adherence to the recipe.
