The lactometer reading and temperature of milk are recorded at the same time. This is the lactometer reading (LR). The corrected value or corrected lactometer reading (CLR) is obtained from the standard table for corresponding temperature. The SNF and/or TS content are calculated using the given formulas. Percent SNF = CLR/4 + (*fat %) +

The working principle is that cement is removed from the mill before overgrinding has taken place. The cement is then separated into a fine fraction, which meets finished product requirements, and a coarse fraction which is returned to mill inlet. ... For more than 50 years vertical mills have been the mill of choice for grinding raw materials ...

When working with huge quantities of milk, chilling is an essential step, even if pasteurization is not a part of it. At temperatures above ambient, milk exits the cow's udder, encouraging fast bacterial proliferation that hastens deterioration. Storing products between 2 and 5 degrees Celsius stops bacterial growth and metabolism.

ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materials become very abrasive; therefore, they are not suitable for highspeed hammer mills. In a typical jet mill, grinding action is caused mainly by particleparticle collisions, so wear to the mill's internals is less of an issue.
