Scraper assemblies for removing carryover material from a conveyor belt or roller are disclosed. In some embodiments, the scraper assembly includes a rotatable cam that causes a scraper blade to remove between a lowered position and a raised position in which the blade contacts a belt or roller. Movement of the blade in the raised position may be bound by a crown of the cam and a cam finger that extends from a main body of the cam.

A belt cleaner is provided which does not damage the belt surface during the scraping operation where tips on an arcuate scraper held in a holder are inclined and pushed against the belt surface with rotary shafts of the holder rotated by a resilient force. A scraper (20) is provided with a flat slope (29) extending in parallel with the belt surface from top edges of the tips (21) in the belt running direction (F), said flat slope (29) is made to contact with the belt surface in a manner of surface-contact connection when the tips are shifted up the posture from a vertical posture to an inclined posture, and a width (W) of said flat slope (29) in the belt running direction with respect to the thickness (t) of said tip (21) is formed under the condition of t<W.

A food production apparatus includes a conveyor belt and a wire scraper. The conveyor belt supports and transports a food product. The wire scraper includes a wire and a motor. The wire is located above and extends across the conveyor belt to temporarily separate the food product from the conveyor belt. Operation of the motor causes the wire to continuously cycle back and forth between 1) movement in a first direction above and across the conveyor belt and 2) movement in a second opposite direction above and across the conveyor belt.
