DeLaval Cream Separator Guide 1940
This DHC series milk cream separator is considered as one of the most precise machines in the milk production line. The product is basically used to separate cream from the milk. It offers such functions as clarification, degreasing, and purification. All connectors are constructed from stainless steel.
Previous to 1878, butter was produced altogether from cream that has been separated in the form of the gravity system. The process was gradual, the cream was typically sour, and the separation was so incomplete that appreciable cream was left in the skim-milk. The gravity method is still used on several farms in this country, but it" has been displaced typically by the machine called the centrifugal cream separator, for which De Laval is liable. The separation of liquids by way of centrifugal force is said to have been first used by the Chinese, but so far as known they never utilized this knowledge to the separation of milk.
From ancient times it's been understood that centrifugal force would separate materials of different specific gravities. Centuries past the Chinese separated juices and oils from fresh fruit pulp by whirling the crushed material in a calabash gourd at the conclusion of a cord. About 1850 experiments began in earnest to apply centrifugal force for separating sugar-cane juice and about 1859 the separating of cream from milk by centrifugal force Was suggested.

This process considerably facilitated the process of separation. The skim milk particles, being the weightier, were compelled against the bottom side of each disc, traveling toward the periphery of the bowl, while the cream particles went along the upper-side of each disc toward the center. This way no clash of cream and skim-milk, occurred, which fact materially raised the skimming efficacy of the Alpha-disc bowl, while itthe capacity of certain size of bowl basically delivered cream in sander and better state.
Avoid bacterial pollution of fresh eggs through the use of an egg separator of some sort rather than the broken egg-shell. I know that television chefs do this all the time--you continually see them breaking eggs nicely right across the center and pouring the yolk from half-shell to half-shell to split up. But do not do it! That damaged shell has germs on the exterior that aren't inside the egg! You introduce germs into the egg white or yolk by performing the distinguishing with the shell. You'll also find the equivalency table on the box or bottle to let you know how much egg white you want for your recipe.
