Why Stone Milling?

Stone Milling has been known as the oldest practical means of grinding food products. Advances in milling technology have introduced roller mills with higher capacities and the ability to separate the germ from other parts of the seed easier. This, however, came at the cost of taking away the natural seed composition. 
Recently the need to eat healthy and more natural have become the cornerstone of every consumer's shopping list. The realization of health risks of processed foodstuffs combined with the obvious benefit of more natural food formed the drive for more natural processing methods. For this reason, Stone Milling has made an astonishing comeback and regained its popularity as the preferred choice of milling. In the last 5 years, the dramatic demand for stone-milled products is evident in the higher prices that stone-milled product get. 
 

Heat

The endosperm, bran, and germ remain in their natural, original proportions when using stone milling. Because the stones grind slowly, the wheat germ is not exposed to excessive temperatures. Heat causes the fat from the germ portion to oxidize and become rancid much faster and much of the vitamins to be destroyed.

Thiamin

Stone Milled product is relatively high in Thiamin compared with roller milled product. Vitamin B1, thiamin, or thiamine, enables the body to use carbohydrates as energy. It is essential for glucose metabolism, and it plays a key role in nerve, muscle, and heart function.

Roller Mills and Other mills

Roller mills, plate mills and impact mills all have metal grinding parts. These milling processes creates a metal taste in the final product that is very easily detected and disliked in some foods.

Flavour

Stone Mills use an open-textured, porous but tough stone that easily absorbs the flavor and aroma of the product essential oils. The stone milling process rubs this aroma into the product similar to rubbing a leave between the fingers releasing a much stronger product aroma distinct and well known to stone millers. A massive advantage is the much longer-lasting aromas in spices and herbs.

Stone Milling

Whether it be herbs, spices or teff seed, Stone milling has made a comeback as the preferred milling process. Introducing lower heat to the germ and providing a more complete product composition, less destructive to vitamins and much stronger final product aroma it is difficult to believe Stone Milling Lines normally requires less starting capital input.

Facts on Wet Milling

1

Heat

Converting a solid product into a liquid within seconds generates a lot of heat. The ability to control the heat in the product is one of the key factors of the design on such a line.

2

Oil Content

The oil content in a product is one of the biggest factors if it will be able to mill or be converted into a paste. Adding oil to the product very seldom have any effect on it's ability to be converted. 

3

Roasting

A products ability to release oil during the milling stage can be drastically changed by roasting the product before hand. Roasting temperature and time is critical. Also the amount of time between roasting and milling is important

4

Mill Design

Converting from solid to liquid takes a lot of power. The conversion process is thus heavy dependent on power. By using a more effecient mill production cost can be cut between 30-40%.

Dry Milling

Dry Milling is the means to grind smaller either seed, spice or herbs to a specified size. The uniformity of the final product is highly dependable on the mill and plant design. Uniformity normally determines the perceived quality of the final product for the buyer.  

Control by Wire

Our Mills is completely controlled electronically. This makes final product more consistent with less breakdowns and minimum interference.
