The biggest mistake in biscuit line selection is confusing theoretical capacity with effective output. A nameplate rating of 1,000 kg/h typically shrinks to less than 800 kg/h of actually saleable finished goods after deducting downtime, sheeting trim, baking rejects, weight‑deviation overfills, and packaging breakage.A real‑world case: forcing line speed up by 30% caused uneven baking, boosting the reject rate from 2% to 9% – and the total cost per tonne of qualified product actually rose by 15%.Two often‑overlooked profit killers are uneven dough‑sheet thickness (responsible for 80% of baking inconsistencies) and weight inaccuracy – a mere 0.3 g overfill per biscuit wastes tens of tonnes of raw materials annually.For smart selection, follow the “Three Don’ts” – don’t fixate on top speed, oven length, or total power. Instead, ask the “Three Dos”: ① stable speed at under 3% reject rate, ② changeover time, and ③ oven‑zone temperature uniformity.A professional equipment supplier’
