Below you'll see a sampling plan that's designed for FTM, but you may find the schedule to be of assistance in how to attain your representative samples for a lot
This plan is used when the equipment is first installed, when major components are replaced (e.g. a separating drum or filter, separating screens, screen plates or perforated screen, feeding screw [i.e. worm], etc.) or when major repairs are made.
Under this sampling plan the operator must test each lot for calcium, protein and bone particle until 10 consecutive lots are in compliance. Once this is achieved, the monitoring plan can be used.
The sample to be analysed shall consist of 20 sub-samples taken during the lot run. If the shift is 8 hours (480 minutes) sampling must be done every 24 minutes (480/20 = 24 minutes). Likewise, if the scheduled lot run is 6 hours (360 minutes) sampling must be done every 18 minutes (360/20 = 18 minutes).
The shift must be a minimum of 4 hours to be considered in this start-up plan, unless the operator's normal operating shift is less than 4 hours.
Each sub-sample should be about 30 grams. The samples may be placed in the same container (e.g. a plastic bag) so that at the end of the lot run it will contain about 600 grams of product.
The tested lots are to be held until receipt of an acceptable laboratory report.
