Abstract: The present invention is an improvement upon such machines as the McGill #3 Rough Rice Milling Machine, and replica models like the McGill #3 Rough Rice Milling, by eliminating the 5 wear points associated with the machine: back plate, rear plate threaded collar, rear plate rings, back plate wear rings and excentric threaded locking nut. Since these five wear areas are of different structural material, back plate: cast aluminum, rear plate: mild steel, eccentric locking nut: cast bronze, the wear rate is not uniform or predictable, thus causing a draft or misalignment of the milling cylinder in the milling basket assembly. The break bars in the Milling Basket Assembly must be in perfect alignment with the shaft that the milling cylinder rotates on. If a misalignment occurs due to wear or uneven wear on the basket assembly then misrepresentative results of the milling yield will occur.

Abstract: A hulling apparatus having a main frame, a moveable support frame, a rotatable drum fixed in position relative to the main frame, a housing supported by the moveable support frame and a hulling chamber formed by the placement of the drum inside the housing. A contact element having one or more brush assemblies is attached to the drum such that the bristles project into the hulling chamber to engage walnuts, pecans or other food products and remove the outer hull therefrom. The walls of the housing are formed from one or more screened panels having openings therein to pass the removed hull material and spiral members thereon to help guide the food products through the apparatus. The housing moves up and down to increase or decrease the size of the hulling chamber. The apparatus speeds the process of hulling walnuts and pecans and more effectively utilizes the brush assemblies.

Abstract: In an apparatus for humidifying polished rice, a conveyor has a tubular housing which defines a predetermined transport path for the polished rice. The conveyor conveys the polished rice, while steering the same, along the transport path. A humidifier is arranged in association with the transport path for adding moisture to the polished rice conveyed along the transport path to humidify the polished rice. A blower is arranged in association with the transport path for causing air to flow therealong. A rice milling system comprises a rice polishing machine and the apparatus connected thereto. The rice polishing machine polishes brown rice to form the polished rice. Polishing of the brown rice to the polished rice raises temperature of the polished rice. The polished rice elevated in temperature is supplied to the housing of the apparatus.
