A door 46 pivotally mounted on the conveyer frame is connected to the tube 42 and pivots to close the opening when the tube 42 moves downwardly under a predetermined weight of food. The amount of food is varied by moving a weight 90 along calibrated balance arm 51, an auxiliary weight 92 and adjusting screw 93 also being provided. Means are provided for returning the balancing means to their original position after the food is discharged from the tubes.
