Extend the shelflife of your flour Herman Roux 1 Bühler
Extend the shelf life of your flour Factors which can influence the shelf-life of flour High amount of bacteria and molds Infested flour High content of moisture levels Micro-organisms Micro-organisms includes bacteria, yeasts and molds High amount of bacteria in lighter particles for grain impurities Conditions for bacteria to grow 2 Bühler IAOM 2014 " Extend the self life of your flour"
How can millers extend the shelf life of flour In order to reduce contamination, one must know in which stage of the process it can be done most efficiently. During the milling process, millers can achieve a substantial reduction of impurities Well designed cleaning flow diagram Pre selection of equipment Optimized process from an engineering approach Sound knowledge of sanitation 3 Bühler IAOM 2014 " Extend the self life of your flour"
How can millers change the shelf life How can the miller extend the shelf-life of flour Reduce the bacteria and molds Control the moisture level of grain Remove live infestation Reduction of bacteria count during the milling process First cleaning reduce : 70% Dampening increase : 20-30% Second cleaning reduce : 30-50% Finish product : 2-20% 4 Bühler IAOM 2014 " Extend the self life of your flour"
