In the ancient times of China, wheat processing method has been conformed to modern powder technology standard. In western countries, stone roller was used at the very beginning, the wheat flour was sieved after grinding, and the windmill was used as driving force. 17th century, the Britain began to use a hydraulic drive two millstone. 1
8th century Hungary created steel mill. In 1823, the flour mill
factory which first applied roller flour mill was established in Poland, first realized the wheat powder mechanization and continuous production. To 20th century, roller grinding mechanism powder technology had spread successively in the countries all over the world, and gradually developed into classified powder producing, repeated screening powder new technology. China in the late nineteenth century introduced roller mill
machine, in the coastal regions some flour factories were established. After the year of 1949, the flour mills gradually moved to raw material origin of wheat. By 1978 the number of flour mills had reached more than 3000, flour yield was 23.4 times than that in 1949. The varieties of wheat flour developed from the original simple production to special flour step by step.
When you are buying a grain mill, you must think about many things, details and ensemble. A good grain mill is adjustable at any time, of high flour products fineness, need not to accompany with special sieving machines. All the flour machine parts is made of the special wear-resisting material or hard alloy, wear-resisting performance is good, replacement parts is of low cost and easy to obtain, conform to the hygiene standards. Generally, the body of the flour machine is not made of casting material, welded the steel plate, in addition to special cutting function, inside the flour machine a sorting device is needed, crushed material by the flow function will be sorted by the sorting device, sorting device is usually replace the crushing equipment sieve, can finish fine crushing and micro powder sorting processing two working procedure at the same time, once into powder without slag, the rate of end product is 100%. Whether the flour machine has anti-block and clearing material function is also very important, flour machine ensures the normal operation and automatic cleaning and crushing a variety of different materials. Mixing evenly, process wheat into flour without residue and circulation crushing, can guarantee the various components of the homogeneous water content. Flour machine can feeding materials with any size, need not crushing can be directly into the machine, and can adapt to all kinds of material of different water content, do not need to match drying equipment. Quality of flour processing machinery is a big problem because it affects the quality of wheat flour directly. That is the reason why you are suggested to buy flour milling machine from reliable manufacturers. Flour processing technology is simple, you can operate it on your own. As the flour is edible, the sanitation of your flour processing place must meet up with the standard.
