How should output temperature rise be tested on a meat grinder?

Fix the raw-material starting temperature, ambient conditions, plate hole size, continuous run duration and probe locations before testing, then grind one homogeneous batch and compare feed versus discharge temperature. For fatty formulations, also check whether fat smears or clings to the plate. Log temperature rise, throughput and all test conditions; housing surface temperature is not a criterion. File the measured rise within your real product window together with post-clean residue findings, and treat the trial sample as a reference for future spare-part matching.
