Angle of repose is another important physical property used for characterization of the bulk of particulate foods such as seeds, grains, flours, grits, and fruits. When granular solids are piled on a flat surface, the sides of the pile are at a definite reproducible angle with the horizontal leveled surface (Fig. 3.8).This angle is called the angle of repose of the material.

Storage systems. Rice storage facilities take many forms depending on the quantity of grain to be stored, the purpose of storage, and the location of the store.. Storage systems can be through bag, bulk, or hermetic containers. Bag storage- g rain is stored in 40−80 kg bags made from either jute or woven plastic; Bulk storage - grain is stored in bulk at the farm or at commercial …

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Working Principle of Rolling Process: The rolling process is a metal forming process, in which stock of the material is passed between one or more pairs of rollers in order to reduce and to maintain the uniform thickness. This process is mainly focused on the cross-section of the ingot or the metal which is forming.
