Configuration of Double-Layer Biscuit Production Lines And Key Equipment Selection

A Thai biscuit and OEM bakery manufacturer upgraded its ageing 500 kg/h production line with Wenva Machine’s 1000 Series automated biscuit production line. Featuring PLC centralised control and a hybrid tunnel oven, the 800–1,000 kg/h solution improved baking uniformity, colour consistency, operational simplicity, and capacity. The project’s success led to a repeat equipment order.

Wenva Machine helped a leading Jakarta snack manufacturer overcome a year of unstable potato-cracker trials. Its customised 1,200 mm automated line, featuring precision forming and a 160 m tunnel oven, reached stable 24/7 output of 800 kg/h within two weeks of commissioning.

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’

This article reviews a real project by Wenva Machine in Malaysia, documenting the complete journey of a biscuit manufacturer building a new production line from scratch. The client, facing capacity constraints, insufficient oven length, and lack of potato cracker production process, connected with Wenva in 2019 through an existing customer referral. Wenva provided a customized 160-meter 1000-type complete line with an extended tunnel oven and dispatched a process specialist from China to Malaysia to address the process gap, helping the client double production capacity and successfully launch a new product line. The project encompassed needs assessment, solution design, cross-border manufacturing and shipping, installation and commissioning, training and acceptance. The client subsequently placed a repeat order for a steel-belt gas-fired oven, with cumulative cooperation exceeding one million yuan. The article summarizes lessons in needs assessment, process capability, cross-border ada
