PURPOSES OF DRYING In food technology, drying is carried out for one or more of the following reasons: 1. To avoid or eliminate moisture which may lead to corrosion and decrease the product stability. 2. To improve or keep the good properties of a material, e.g. flow ability, compressibility.

The working principle of this pump is, it pushes the underground water to the surface through changing energy from rotary to kinetic and finally into pressure energy. This process can be done through the water being dragged into the water pump first, where the revolution of the impeller drives the water using the diffuser.

A drilling rig is an integrated system that drills wells, such as oil or water wells, in the earth's subsurface.Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called augers.Drilling rigs can sample subsurface mineral deposits, test rock ...
