Wafer Biscuit Production Line

Short answer: A wafer biscuit production line mixes a thin batter, bakes it between heated plates into crisp sheets, spreads cream between sheets, cools the stacked “books” and cuts them into finished wafers, with chocolate coating as an option. Sheet size, plate pattern and the cream recipe decide the oven, spreader and cutter.

How it works

1. Batter mixing – flour, water and small amounts of other ingredients are mixed into a smooth, low-viscosity batter.
2. Baking – batter is dosed onto heated plates that close and pass through the oven; each pair produces one sheet.
3. Sheet cooling – baked sheets cool and stabilise on a conveyor.
4. Cream preparation and spreading – cream is mixed and spread onto sheets by rollers.
5. Stacking – creamed sheets are stacked into multi-layer books, topped with a plain sheet.
6. Cooling – books pass through a cooling tunnel so the cream sets.
7. Cutting – books are cut into fingers, bars or squares with wires or saw blades.
8. Coating and packing – wafers can be enrobed in chocolate, then packed.

Which configuration fits

Form	Suits	Watch out for
Flat wafer	Cream wafers, wafer sticks and bars	Cutting waste, cream setting time
Hollow wafer	Cones and shaped shells to be filled	Separate moulds, filling line
With chocolate coating	Premium coated bars	Enrober and cooling tunnel space, chocolate handling

The oven decides line output; the creaming and cutting sections are sized to keep up with it. Number of plate pairs, bake time and sheet size together set how many sheets per hour the oven delivers, so a change in sheet size changes capacity. Cutting waste (edge trim and broken pieces) is usually reworked into cream, which is worth planning for.

Where it sits in a line

The wafer line often sits next to a biscuit production line and shares packing. Finished wafers are typically packed in flow wraps, then passed through a food metal detector and an in-line checkweigher. Cleaning and conveying between sections can use hygienic conveyors.
