19 APPENDIX B19.1 PARAMETER DEVELOPMENT - FOODS INDUSTRYFollowing are the guidelines for developing parameters.TEST TEMPERATURESBe sure to use a temperature that is high enough to drive off all the moisture but doesnot degrade the material in any appreciable way.If, after establishing a test temperature, a shorter test time is desirable, try usingHISTART temperature control. Begin with a HISTART temperature that is 20°Chigher than the test temperature.STANDBY TEMPERATURE: 80°CAdjust only with materials that would be affected with this elevated standbytemperature.When using small sample sizes of materials that lose moisture quickly, it isrecommended that the pan or the pan w/filter paper (if used) be cooled after the pantare and before adding the sample. This can be done quickly and easily by removing thepan or pan w/filter paper and fanning them back and forth a few times.ENDING CRITERIA:If expected moisture content is greater than 20% or less than 0.5%, use RATE. Ifgreater than 20% adjust rate in increments of 0.25/minute.IE:0.50%/minute0.75%/minute1.00%/minute1.25%/minuteIf less than 0.5%, adjust rate in increments of 0.05% beginning at 0.25% and adjustdown as needed.If expected moisture is between 0.5% and 20%, use PREDICT.MAX-1000 - Relaxed predict72
