Model MWF-OS Sanitary Weigh Belt Feeder
Thayer Scale’s Model MWF-OS’s open style construction makes regular cleaning a breeze.
Thayer Scale’s Model MWF-OS is Thayer Scale’s sanitary built-to-survive weigh belt feeder. With an all stainless steel construction and two wash-down construction levels, the MWF-OS is the ideal weigh feeder to meet sanitary requirements for the food industry. Major food brands rely on this feeder to accurately measure a range of materials with varying particle shapes and densities.
With two standard belt widths and six standard conveyor lengths, the MWF-OS can be customized to any process layout, sanitation requirement or budget. The MWF-OS features a low maintenance design and can be economically reconfigured for future capacity needs for a long-term, low cost of ownership. Its open construction design is easy to clean to provide Precision Measurement and Extreme Reliability.

Core Technologies
🌀 Head Pulley Drive System
Discharge pulley drive to maintain uniform belt tension and positive belt alignment design eliminates the need for belt tensioners and trackers. Simplified conveyor construction minimizes preventative maintenance.
📏 Tail Pulley Mounted Speed Encoder
Measures the true speed of the belt via rotation of the idling pulley, belt slippage or breakage is immediately detected because the idling pulley stops rotating.
📐 Customizable Engineered Options
Multiple transmission options that utilize commercially available components, two belt cleaner options to remove fines or residue and maintain zero measurement stability.
🔧 Optional Automated Test Weight Positioning System
Automatic test weight positioning mechanically exercises the scale for safe, verifiable calibrations which can be completed automatically from a supervisory control system or manually initiated by an operator.
🛡️ Full-Length Adjustable Skirts
Full length product containment skirts provide field adjustment of the gap gradient in the direction of material flow to relieve/eliminate particle jamming to maintain accurate load measurement. Available sealing strips in the inlet transition area add an extra layer of material confinement that avoids material spillage.
