Thayer Scale’s HWF Hygienic Weigh Feeder for Enhanced Food Safety Processing

Thayer Scale’s HWF Hygienic Weigh Feeder for Enhanced Food Safety Processing
4 Feb 2024  |
The Model HWF Hygienic Weigh Feeder is designed to work in conjunction with the LWF-V sanitary Loss-in-Weight feeder to ensure precise delivery of topical ingredients such as anti-cake powders, seasonings, and material drying agents.

It provides a flow rate measurement solution for the enhanced food safety processing segment. The Model HWF Hygienic Weigh Feeder is specifically engineered to accurately measure the rate of flow, control the rate of flow or dose conveyed, in-process bulk materials for food safety segments that require strict adherence to 3-A standards, including Individual Quick Frozen IQF vegetables, ready to eat food service, meat processing, poultry processing, cheese conversion (shred, grate), seafood and high meat inclusion premium pet food.

Thayer Scale developed the Hygienic Weigh Feeder to help the sanitary space meet the challenges of this new era of smarter food safety initiatives. HWF is designed and built in accordance with the applicable provisions of NAMI (North American Meat Institute), 3-A, NSF and USDA specifications for industry segments that require compliance with food traceability rules and food safety plans. Like all Thayer Scale solutions, the Model HWF ensures continuous, trouble-free operation despite frequent, caustic washdowns and other challenges of sanitary processing environments.
