A material-handling conveyor means for food materials or the like including a horizontally disposed support beam having a first bearing means secured thereto adjacent one end thereof and a second bearing means adjustably movably mounted at the other end thereof. A driven shaft extends through the first bearing means horizontally from the beam and an idler shaft is mounted in the second bearing means and extends horizontally therefrom. The shafts support pulleys which have an endless conveyor belt mounted thereon. The conveyor belt is mounted in a casing which is secured to and supported by the support beam. One side of the casing is closed by a removable cover to facilitate the cleaning of the interior of the casing. A belt-takeup assembly is connected to the second bearing means to permit the idler shaft to be moved with respect to the driven shaft to adjust the tension in the conveyor belt. The takeup assembly includes means to maintain the idler shaft in a parallel relationship to the driven shaft as the tension in the conveyor belt is adjusted.
