58 MILLER / NOVEMBER 2018 “Pneumatic conveying represents an important topic in engineering and is encountered in a variety of industrial processes. Widely used in flour industry to handle and transport dry and free-flowing powdered and granular material because it is suitable for variety processes. Fine particles of lees 1 micron, as well as 15 mm rocks, can be conveyed vertically and/or horizontally from distances of few meters to a few kilometers at rates of hundreds of tons per hour requires less control and maintenance, and it is cleaner easier to automate. Great progress bulk transport improves the hygiene of production systems totally enclosed, and dust generation is minimized.” Main purpose to present multiple sour- ces of studies to explore what exist behind scenes and realize scope activities of flour milling industry and bulk transportation addresses a lots of verification and valida- tion facts of safety quality assurance. Food and Drug Administration FDA “Current Good Manufacturing Practices and Ha- zard Analysis and Risk-Based Preventative Control for Human Food”. The Flour Milling industry is considered a low-risk area within the food handling enterprises since the flour is mainly used for baking purposes. However, there are pathogens that produce toxins that can be heat stable and can cause illness even after the product has been baked such as Bacil- lus and Staphylococcus species.
