Large Capacity Concrete Workshop Wheat Flour Mills

A. Wheat Cleaning and Dampening

A cleaning system composed by professtional machines used to remove out all impurities mixed with wheat seeds, such as dust, metal stuff, soil block, stone, light straw, etc. Perfect cleaning is the most basic foundation to produce high quality flour and guarantee longer services life in machinery. Dampening followed after impurities cleaning to make sure the seeds are in the required moisture to flour milling. Accurate moisture adjustment is critical in increasing flour exrtracting rate and bran separation.

B. Wheat Flour Milling, Sieving and Purifying

By functions of cutting and grinding in Pneumatic Roller Mills, the seeds will crushed into powder mixture of flour and bran. Cyclical movement of flour milling, sieving, and grading gives more and more satisfied flour to next step, and bran also collected in different place for animal feed. Purifiers offer high quality in flour, and more flour types for different usage, such as semolina. This is a most complicated system in wheat flour milling industry, dozens of roller mill, square plansifter and purifier work together to carry out designed productive capacity required. 

C. Flour Moving and Calculating Process

Satisfied flour will be collected step by step from milling section and delivered to storage bins waiting for packing. Screw conveyors empolyed to flour delivery, and electric scales are usually used to calculated the flour extracting rate in a certain period. Bran brushers can separate more flour from bran to higher the total flour extracting rate in the whole productive process. 

D. Flour Storaging and Sample Inspecting

The large flour mills usually running 24 hours a day, and more than 26 days a month. Flour bins then demanded for temporary storage, and several automatic flour packing machine required to pack flour in different weight, like 1kg, 2kg, 5kg, 10kg, 25kg, 50kg, etc. Flour inspecting is required to examine the content of nutritions such as gluten, protein, whiteness, etc.

E. PLC Control System

PLC is widely used in big and large wheat flour mill for operating and monitoring on the whole productive process to save hands and cost. Strong MCC cabinet, Schneider electric components, high-temperature resistant cable and wires. Only 4-5 workers needed per shift in a large flour mill with PLC system.
