Thayer Scale Provides The Coffee Processing Industry With Weighing Solutions

17 Apr 2024  |
Coffee is the second most traded commodity in the world after oil. Global coffee production exceeds more than 11 million tons annually, providing more than two billion cups of coffee.

Thayer Scale provides the coffee processing industry with food safe gravimetric and volumetric feeder solutions for industrial coffee roaster. Thayer Scale equipment is used in green bean blending to improve inventory control and make the blending process easier to manage with fewer operators by automating the weighing process. After cleaning, green coffee beans are conveyed into storage hoppers based on their origin / variety.

Combinations of bean varieties are drawn from these storage hoppers in precise amounts and blended to achieve specified flavor profiles during roasting. Legacy industrial coffee roasters utilize a gravity batch system that consists of a multi-chamber storage hopper, fed by a rotary distributor and chute work system that directs beans to the appropriate section of the multi-chamber storage hopper. The outlet of each chamber features a transition funnel, chute work and slide gate that directs green beans to a common scale hopper. Process-specific facilities are required to accommodate the ~200-feet of stack up height of these gravity batch systems.

Thayer Scale has the most comprehensive line of weigh belt feeders on the market today. With feed ranges from 30 pounds/hour to 3,000 tons/hour Thayer Scale can offer a customized solution for your material handling needs.

Thayer Scale Equipment for Green Bean Blending

Contemporary industrial coffee roasters typically lease multi-use industrial warehouse space from third party management groups whose building design readily supports repurposing to meet the needs of future clients.

To fit within these structures, green bean blending and roasting systems utilize a green bean storage array consisting of multiple, multi-quadrant hoppers, each fed by multi-position diverter valves. Each pair of silos can discharge onto a common Thayer Scale Model “MWF” Weigh Belt based on the positioning of slide gates at the bottom of each silo. Each weigh belt delivers high accuracy green bean blends in a low-profile stack-up that readily fits within today’s building designs. The weigh belts eliminate gravity chute work and product free fall height, significantly reducing product damage. Gentle product handling maintains a higher bean quality and generates larger yields for the producer.

The weigh belts seamlessly integrate with modern roasting profile software facilitating automatic, real-time adjustments that mitigate variances in green bean characteristics. Each weigh belt accurately delivers a wide range of batch sizes to a high level of precision, allowing processors to adapt to rapidly changing flavor trends and develop more customized product SKUs for their clients.
