Continuous & Batch Baking

Tunnel & Baking Ovens

Start with the production pattern: a continuous baking band or batches on trays. Then compare electric, fuel-fired and hybrid tunnel heating against your product, available energy and required baking profile.

Diesel Tunnel Oven

A diesel tunnel oven is the practical answer for biscuit factories where pipeline natural gas simply does not exist — the reality across much of Africa, the Middle East, and South Asia. Wanttone’s diesel tunnel oven burns standard diesel or light fuel oil in high-efficiency burners, transferring heat to the baking chamber through a sealed heat exchanger so combustion gases never touch the product. The result is the same vigorous, stable bake that gas-fired ovens deliver — multi-zone control, even color, continuous 24/7 operation — powered by a fuel that is available and affordable in almost every market. Built in project-specific lengths with up to four zones and heavy rock wool insulation, this biscuit tunnel oven lets you locate your plant where the market is, not where the gas pipeline ends.

Electric Tunnel Oven

An electric tunnel oven is the cleanest and most precisely controllable baking solution for industrial biscuit production. Wanttone’s electric tunnel oven uses high-efficiency electric heating elements combined with multi-layer hot air circulation to deliver uniform heat across the full width of the baking chamber — with zero combustion gases, zero on-site emissions, and temperature accuracy within ±1°C per zone. Designed for continuous operation in medium to large biscuit, cookie, and cracker factories, this biscuit baking oven is available in standard 620 mm and 800 mm band widths, with oven lengths from 12 m to 60 m and up to four independently controlled temperature zones. For plants with a stable power supply, emission regulations, or clean-room production requirements, an electric tunnel oven is the lowest-risk, easiest-to-maintain choice on the market.

Gas Tunnel Oven

A gas tunnel oven is the workhorse of high-capacity biscuit manufacturing — and the most economical baking solution wherever natural gas or LPG is readily available. Wanttone’s gas tunnel oven burns fuel cleanly inside high-efficiency combustion tubes, delivering heat to the product through three simultaneous mechanisms: convection from circulating hot air, conduction through the stainless-steel conveyor band, and direct radiation across the baking chamber. The result is lower energy cost per ton, faster thermal response, and the strong, stable heat that crackers and hard biscuits demand. Built in lengths up to 60 m with two to four automatically controlled zones and digital temperature display, this biscuit tunnel oven runs on natural gas, LPG, or diesel — configured to your local fuel infrastructure and production targets.

Hybrid Tunnel Oven

A hybrid tunnel oven gives biscuit manufacturers something no single-energy oven can: the freedom to choose — or combine — the ideal heating method for every product and every zone. Wanttone’s hybrid tunnel oven integrates gas heating, electric heating, and infrared heating in one continuous baking tunnel, letting operators assign direct-fired gas to zones that need fast, vigorous heat, hot-air or electric heating to zones that need precision, and infrared where deep, even penetration is required. The result is one biscuit baking oven that handles hard biscuits, soft biscuits, soda crackers, butter cookies, and pretzels on a single line — with energy optimization built in and an optional waste heat recovery system that recycles exhaust energy back into the process. For multi-product factories and plants facing uncertain energy prices, the hybrid tunnel oven is the most future-proof investment in the category.

Tray Rotary Oven

A tray rotary oven — also called a hot-air rotary rack oven — is a batch-type baking oven in which a full trolley of trays rotates slowly inside a forced-convection chamber, so every tray receives identical heat and airflow. Wanttone’s tray rotary oven gives small and medium bakeries, in-store bakeries, hotels, and central kitchens industrial-grade baking quality without the footprint or capital of a continuous tunnel line: roll the loaded rack in, set the program, and roll out evenly baked bread, cookies, cakes, or pastries — top and bottom trays in the same color, no mid-bake tray swapping. Available in electric, gas, and diesel versions, the rotary rack oven is the most versatile single baking investment for growing bakery businesses.
