Great progress bulk transport improves the hygiene of production good storage and transportation required ac- curacy & reliable dosing ingredients is an essential part of ensuring production efficiency obtaining a homogeneous consistency test with good properties. If the properties of the test do not correspond to the required parameters, it is usually difficult to provide ap- propriate subsequent processing to obtain cookies of the desired quality. The require to indicate special attentio in transport the ingredient, and development of equipment a well-known tanker and railway wagons with lifting ca- pacity from 5 to 100 tons, for the transportation of raw material in powdered and liquid some technical aspect of bulk transport systems are diverse, the following in- formation should be sufficient understand the general principles. In addition, the technical issues devoted the wheat flour ingredient. Flour is normally supplied in bulk PD trucks and rail cars. Of these, flex it is fed into the bankers with air (from the installation on the tank or the Blowers companies). To unload 20 - 30 tons usually requires 20 - 30 minutes. Pneumatic transportation of flour usually a large air flow and to avoid significant drying of flour should pay attention to its temperature and humidity. The analyses of sensitivity on weights show that the ranking robust with either cereals and grains or dried protein products always being in the top position. Wheat flour & Corn Flour ranking the highest grains Moisture content. Why is it important to know the Grains Moisture content? Determining moisture content is an essential first step in analyzing Wheat or Flour Quality since this data is used for other tests. Flour millers adjust the moisture in wheat to a standard level before milling. Moisture content 14% is commonly used as a conversion factor for other tests in which the result are affected by moisture content. Moisture is also an indicator of grain storability. Wheat or Flour with high moisture content over 14.5% attracts mold, bacteria, and insects, all of which cause deteriora- tion during storage and transportation. Wheat or Flour with low moisture content is more stable during storage. Moisture content can be an indicator of profitability in milling. Flour is sold by weight, grain is bought by wei- ght, and water is added to reach the standard moisture level before milling. The more water added, the more weight and profitability gained from the wheat. Wheat with too low moisture, however, may require special handling & processes equipment before milling to reach the standard moisture level and special vehicle for bulk transportation. In-Line Filter Remove Contaminations From Pneu- matic Trailer Air Supply Contamination of product is one of the biggest concer- ns for carriers that use pneumatic trailers to haul food, plastics, or other high-purity commodities. Microscopic particles carried by the conveying air can cause major contamination problems. Extremely fine airborne pollutants can elude an air in- take filter. Material from the air intake filter and lubrica- ting oil from a blower can enter the conveying air. All of these can result in product loss, silo cleanup costs, and downtime. Moving air transports dry, free-flowing gra- nular materials within conveying line. The basic types of pneumatic conveying are dense and dilute phase. Dilute phase pneumatic conveying is the method most commonly used in the general process industry and on dry bulk trailers. Dilute phase conveying uses a relatively low pressure (less than 18 psi) and high air velocity (1000 cfm). The conveying material occupies less than 40% of the cross-sectional area of the conveying line. Bulk con- veying equipment includes a vacuum and dense-or dilute pneumatic conveying.
