Milling and processing - IRRI Rice Knowledge Bank

Milling is a crucial step in post-production of rice. The basic objective of a rice milling system is to remove the husk and the bran layers, and produce an edible, white rice kernel that is sufficiently milled and free of impurities. Depending on the requirements of the customer, the rice should have a minimum number of broken kernels.

What are the Steps in Milk Processing? (with pictures)

Clarification is a step in milk processing that ensures the milk will be free of bacteria and debris. Milk is put into large vats that continually spin. The spinning causes the milk to separate from debris and floating bits of bacteria. After clarification is completed, the milk is spun once again to separate heavier and lighter milks.

Key factors affecting milk production and quality - Jacoby

Heat and humidity are the factors with largest impact. If nighttime temperatures cool, cows get a chance for cover even in hot seasons.
