The milling process in larger commercial mills combines a number of operations that produces higher quality and higher yields of white rice from paddy or rough rice. The process involves: 1. Pre-cleaning the paddy prior to milling 2. Removing the husk or outer layer from the paddy 3. Polishing or whiting the brown rice to

Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.

Jet mills operate in compressed air, gas or high pressure superheated steam. Jet mills have no moving parts, thereby eliminating contamination due to contact with external grinding media. It is also an ideal process to grind heat-sensitive and waxy material because no attritional heat is generated. Jet mill works on fluid energy.

Step 4: Pressing. The peanuts are transfer by conveyor and fed through the hopper of screw press machine. Continuous transport of material by the screw shaft causes pressure to increase to a level needed, which increases friction inside the screw press and generates heat which lowers viscosity of the oil in the crushed seeds thereby increasing the oil flow rate.
