How should I select a meat grinder for eight hours of continuous operation?

For an eight-hour duty cycle, first confirm the maker rates the machine for continuous load rather than intermittent use. Check how heat is dissipated, along with bearing grade and the reduction gear, since these govern temperature rise and stability over a long run. Give the supplier your daily hours, batch weight, cleaning frequency and output target so the model suits your actual duty. During a trial, run a full shift and log current, temperature rise, vibration and net output, watching whether the plate and feed still perform late in the run. At handover, process your own product continuously, measure core temperature, and treat those figures as the pass mark for going into production.
