Disclosed are a supply apparatus for a fixed amount of washed rice and an instant rice manufacturing system having same. The supply apparatus for a fixed amount of washed rice according to one embodiment of the present invention comprises: a washed rice hopper provided at one side of an apparatus body and forming a place where washed rice is stored therein; a plurality of upper chutes which are provided in the lower region of the washed rice hopper and through which the washed rice in the washed rice hopper falls individually; a plurality of lower chutes provided in the same number as the upper chutes, spaced apart from each other in the lower region of the upper chutes, and supplying the washed rice falling from the upper chutes to instant rice containers; and a washed rice delivery unit which is disposed between the upper chutes and the lower chutes, is at least partially movable, and simultaneously delivers the washed rice on the upper chute sides to the lower chutes.

A grain cart includes a supplying container and a grain transfer element coupled to and configured to receive grain from the supplying container. The grain transfer element is inclined upwardly, forwardly, and laterally outwardly from the supplying container. A control spout is coupled to and projects laterally outwardly from the grain transfer element. A first control spout actuator is configured to move the control spout about a first axis between a forward discharge direction and a rearward discharge direction to direct discharged grain forwardly and rearwardly into a receiving container. A second control spout actuator is configured to move the control spout about the second axis between a generally downward discharge direction and a laterally outward discharge direction to direct the discharged grain generally downwardly and laterally outwardly into the receiving container.

A method for transferring proppant that has been delivered to a worksite by a transport vehicle to a blender includes creating a pile of the proppant, using an unloader and/or a stacker, at a proppant inlet of a self-feeding conveyor and transferring the proppant, using the self-feeding conveyor without operator interaction and a metering conveyor, from the pile to the blender. The method further includes controlling a mass rate, using the metering conveyor, to vary at least one of a speed of the self-feeding conveyor, a speed of the metering conveyor, or a variable opening onto the self-feeding conveyor and/or the metering conveyor; and supplying the proppant, using the metering conveyor, to the blender at a selected rate.
