Homogenizers | Dairy Processing Handbook

Homogenization theories. Many theories of the mechanism of high pressure homogenization have been presented over the years. For a low-viscous oil-in-water dispersion like milk, where most of the droplets are in the order of one µm (10 –6 m) in diameter, two theories have survived. Together, they give a good explanation of the influence of different parameters on the homogenizing effect.

MODULE 3 – BREACHING-BREAKING-CUTTING- BURNING

Cement is a fine gray powder, and once mixed with water, sand, gravel or stone becomes concrete. The strength and durability of concrete depend chiefly on the amount of water used. If too much water is used the cement paste will be too weak to hold the aggregates together. Generally, within limits the less water used the stronger the concrete.
