Tunnel Oven Cookie Production Line Weishaupt Burner 3800x1300mm Continuous Baking

Cookie colour is the first quality signal a buyer sees, and it is decided inside the tunnel oven. Uneven heat across the belt width produces dark edge cookies and pale centre cookies from the same batch, and the packing line then rejects a percentage of every run. This tunnel oven cookie production line uses a Weishaupt burner, three independent PID zones and ducted air circulation across a 3800 by 1300mm baking chamber to deliver consistent colour from edge to edge at 150 to 250 kg per hour.

The three zones are set as a baking curve: the first zone sets the base, the second develops colour and the third dries the centre. Profiles are stored per product, so a plant running butter cookies, filled cookies and shortbread recalls the correct curve with one touch. The stainless wire mesh belt is kept centred by a pneumatic tracking system, and the 100mm rock wool jacket holds heat while keeping the outer skin safe to touch, which reduces both gas consumption and operator risk.

• Weishaupt Burner: A Weishaupt burner is specified for stable modulation and clean combustion, and local service is available in most export markets, which matters when a burner needs attention.
• Three Zone Baking: Independent top and bottom PID zones let the operator build a baking curve that sets the base, develops colour and dries the centre in sequence.
• Even Colour Across Width: Air circulation ducts distribute heat across the full 1300mm belt width, so edge cookies match centre cookies and the rejection rate at the packing end falls.
• Automatic Belt Tracking: A pneumatic tracking system keeps the wire mesh belt centred, avoiding the edge fraying that stops a line on a weekend shift.
• Curve Editor: Baking profiles are stored per product, so a plant running four SKUs recalls the correct curve instead of rebuilding it by trial and error.
• Insulated Shell: The 100mm rock wool jacket keeps the outer skin cool, protecting operators and reducing the gas consumed to hold temperature.

Suits commercial bakeries, biscuit plants, frozen dough processors and contract manufacturers. It runs cookies, biscuits, shortbread, crackers and bar products, and it pairs with any depositor or wire cut forming machine on the same tray pitch.

The oven ships as bolted modules with numbered joints, the burner travels in its own crate with manufacturer documentation, and an installation drawing plus commissioning checklist is supplied. A spare thermocouple, belt repair kit and burner nozzle set are included.

Buyers comparing ovens usually ask two questions first: which burner, and how even is the colour across the belt width, because those two answers decide the rejection rate.
