Milling (Crushing) of Grain
Milling, also known as crushing, is a process of breaking down cereal grains into smaller pieces to prepare them for further processing in food production. This process is commonly used in the milling industry and in brewing to produce flour, grits, or malt grist. Milling is an important step to make the nutrients in the grain accessible and to facilitate further processing.
Characteristics and Advantages of Milling
- Nutrient retention: Milling largely preserves the nutrients of the grain.
- Efficiency: The process allows for quick and effective crushing of large quantities of grain.
- Versatility: Various types of grain such as wheat, barley, oats, and corn can be milled.
- Improved processing: Milled grain is easier to process further.
Milling Methods
- Roller mills: Grain is crushed between rotating rollers. This method is commonly used in the milling industry to produce flour and grits.
- Hammer mills: Grain is crushed by rapidly rotating hammers that force the material through a screen. This method is often used in animal feed production.
- Grain mills: Traditional mills where grain is crushed between two millstones. This method is often used to produce coarse grist and wholemeal flour.
Applications of Milling
- Milling industry: Production of flour, grits, and other grain products.
- Brewing: Milling malt for beer production to make the starch accessible for the brewing process.
- Animal feed production: Crushing grain for the production of animal feed.
- Home kitchens: Using small grain mills to produce fresh flour and grist for personal use.
Safety and Environmental Aspects
When milling, appropriate safety measures should be taken to prevent injuries from rotating parts and dust formation. This includes wearing protective clothing, gloves, and respiratory masks. Environmental aspects include minimizing waste and proper disposal of milling by-products.
Conclusion
Milling is an important grain crushing process used in many industries. It enables the efficient processing of grain into flour, grits, and other products and contributes to the production of high-quality food.
