Dwell time in tablet compression
WebSep 2, 2011 · Elastic tablets tend to expand after compression, thus causing a decrease in measured tablet hardness. Figure 1: Half-normal plot of tablet hardness. The half-normal plot indicates that factors A, C, D, and E, and interactions CD and CE significantly affected the hardness response. WebIf the tablet needs more dwelling time, pre-compression can be done twice with a higher force the second pre-compression step. 3. Slow the Press Down. By decreasing the speed of the press, the dwell time or the time that the tablet is under pressure is increased.
