Grain Mills
What it is: Grain mills are specialized installations designed to process cereal crops into flour and other products. They can range from small household mills to large industrial units capable of handling large volumes of grain.

What they can produce:
• Flour: various types, including wheat, rye, corn, and others.
• Groats: for example, buckwheat or oatmeal.
• Bran: a by-product that can be used for animal feed or in bakery production.
• Finely ground products: such as flour for specialized diets or recipes.

How it works:

1. Grain loading:
   o Grain is fed into the mill from a pre-cleaned and prepared batch. Cleaning includes removing impurities, stones, and other contaminants.

2. Grinding:
   o Depending on the type of mill, the grain passes through various mechanisms such as millstones or hammer systems.
   o Millstones can be flat or conical and provide a more uniform grind.
   o Hammer mills use hammers to break the grain into small particles.
   o The grinding process can be multi-stage: first coarse grinding, then finer grinding, producing flour of the required fineness.

3. Sorting:
   o After grinding, the finished product passes through sorting machines that separate flour by type and quality. This ensures a uniform product and removes any large particles.

4. Packaging:
   o Finished flour and other products are packaged in bags, containers, or other packaging for storage and transport. Packaging can be automated using packing machines.

Advantages of using grain mills:
• Flour quality: Modern mills ensure high-quality products while preserving nutrients.
• Product variety: Mills can produce different types of flour and groats to meet various market needs.

• Texture and flavor retention: Rapid freezing prevents cell damage, maintaining original texture and flavor.
• Extended shelf life: Frozen products can be stored for long periods without quality loss, making them convenient for use at any time.
• Production flexibility: Blast freezing allows manufacturers to quickly process large volumes, which is especially important during harvest season.

Freeze-drying equipment is designed to remove moisture from fruits and vegetables using a sublimation process in which ice turns into steam, skipping the liquid phase. This method helps preserve the nutrients, flavor, aroma and texture of the food, and allows for long-term storage without preservatives.

The process begins with preparing the food: it is washed, peeled and cut. In some cases, fruits and vegetables are blanched to preserve color and texture. The food is then frozen in special chambers, after which it is placed in a vacuum chamber. Here, low pressure is created and the temperature gradually increases, which allows the ice to turn into steam. This process removes 90-95% of the moisture, leaving the food light and durable. Finished freeze-dried food is packed in airtight containers to protect it from moisture.

The benefits of freeze-drying include preserving nutrients, easy storage and transportation, a long shelf life without refrigeration and ease of preparation – just add water to reconstitute the food
