The alkaline bath is the signature step that sets pretzel biscuits apart from regular biscuits.
Alkaline Water Pool: Raw dough pieces pass through a food-grade pool containing sodium carbonate (Na₂CO₃) or food-grade sodium hydroxide (NaOH) solution.
Temperature Control: The solution is maintained at the correct temperature to ensure even dipping.
Precise Timing: Dipping time is controlled to a few seconds, ensuring proper coating without damaging biscuit structure.
The alkaline dipping process initiates a chemical reaction on the biscuit surface that:
Produces the signature golden-brown color during baking (via the Maillard reaction).
Enhances crispness and a unique crunchy bite.
Creates the authentic alkaline biscuit flavor recognized worldwide.
Immediately after dipping, the biscuits may undergo a topping application stage:
Common toppings include salt crystals, sesame seeds, or spices.
The alkaline coating allows toppings to adhere firmly, ensuring they stay intact during baking and packaging.
Once dipped and optionally sprinkled, the biscuits are transferred into the tunnel baking oven.
Baking Process: Controlled heat ensures even baking.

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’
