Description
MWF-ES Light Industry Sanitary Weigh Belt Feeder
Thayer Scales’s Model MWF-ES Sanitary Enclosed Construction Weigh Belt Feeder is used for processing of snack food, cereal, pasta, pet food or any other application where hygiene and ease of cleaning is important. The MWF-ES frame is constructed from 304 or 316 stainless steel and is designed for “no-tools” disassembly. The Model MWF-ES can provide either “closed loop” gravimetric control of material feed rate or precise convey rate measurement and totalization of an uncontrolled or intermittent material supply.
Slack belt design for more stable accuracy
The MWF-ES belt is driven from the head pulley located at the outlet end of the feeder, rather than the tail pulley located at the end inlet. This permits lower belt tension during operation for better sensitivity and more stable accuracy. The head pulley is crowned to prevent belt tracking problems and is sheathed in rubber lagging to prevent belt slippage.
Inlet dimensions custom tailored
Ensures uniform withdrawl of material from storage. Very careful consideration is given to density, particle size and handling characteristics of your material.
Speed sensor mounted at idling tail pulley
Measures the true speed of the belt via rotation of the idling pulley, not an inferred belt speed based on motor speed. Belt slippage or breakage is immediately detected because the idling pulley stops rotating.
Automatic calibration
Thayer Scale’s optional automatic test weight mechanism provides a means for applying a precision test weight to allow completely automatic calibration. The calibration sequence can be initiated via the weigh belt instrument keypad or via a contact closure. The need for test chains is eliminated.
Screw adjustable idler alignment
The idlers adjacent to the weigh idler are mounted on jacks for easy alignment in the field. All idlers are mounted on individual CEMA brackets, permitting removal to either side without major framework disassembly or belt removal.
Full length adjustable skirt boards
Tapered and flared from the inlet to the discharge to prevent pinching of material between the skirt and the belt. Skirt boards are located inside the belt flanges to provide two barriers to contain material and prevent spillage.
