Abstract
In order to predict the weight loss of a powder on the dividing and packaging machine, adhesion of Lactose G® and Crystalline Lactose with sieving particle diameters of 32/50, 50/100, 100/200 and 200 mesh pass were investigated. The examination of the apparent adhesion to the polyethylene laminate glassine paper and to four types of materials (processed glass beads shot, teflon, ground and crude stainless steel 304) used in the dividing and packaging machine showed a larger adhesive in the smaller size of both lactoses. There were significant correlations between the apparent adhesion and weight loss to the glassine paper and to the ground stainless steel 304 in each of the lactoses. No correlation was seen between the adhesive force of polyethylene laminate glassine paper obtained from the shear test and wall friction test on weight loss.It is concluded that the measurement of apparent the adhesion of powder is suitable for the anticipation of weight loss.
