Technical description • Model / internal code: HL-STTO-16. • Equipment type: industrial continuous gas tunnel oven for bakery and food production. • Commercial configuration: single tray line. • Configured total length: 16m. • Baking area: 14m. • Compatible tray formats: 400×600mm and 600×800mm. • Simultaneous capacity: up to 37 × 400×600mm trays or 18 × 600×800mm trays. • Baking chamber width: 750mm. • Baking chamber height: 300mm. • Continuously adjustable conveyor speed: 600–3000mm/min. • Specified reference output: 1.5–7.5 trays/min. • Adjustable baking time: 5–25 minutes. • Temperature range: 25–350°C. • Fuel: LPG or natural gas. • LPG consumption: 4.5kg/h. • Natural gas consumption: 5.6m³/h. • Electrical supply: 380V three-phase. • 220V and 420V available as optional electrical configurations. • Specified electrical power: 3kW. • Main structure manufactured from 6mm A3 carbon steel. • Gas burner manufactured from #430 stainless steel. • Manufacturer-specified gas burner warranty: 8 years. • Manual ignition system. • Independent electrical control panel. Commercial description The Hongling HL-STTO-16 is an industrial continuous gas tunnel oven designed for industrial bakeries, baked-goods factories, pastry production plants, prepared-food manufacturers and automated food-processing lines requiring a continuous flow of trays through the baking process. The commercial configuration has a 16m total length with a 14m effective baking area, allowing the oven to operate as an integrated stage within a continuous production line. Conveyor speed can be continuously adjusted between 600 and 3000mm/min, providing approximately 5–25 minutes of baking time depending on the product, recipe and selected operating conditions. Its 25–350°C temperature range supports a broad variety of bakery, pastry and baked or pre-cooked food applications. The oven accommodates standard 400×600mm and 600×800mm trays, with a specified simultaneous capacity of up to 37 × 400×600mm trays or 18 × 600×800mm trays. This makes the system suitable for continuous processing of bread, pastries, laminated products, empanadas, savoury baked goods, biscuits, pre-cooked foods and other products processed on baking trays. Continuous conveyor adjustment allows residence time to be adapted to products with different thicknesses and baking requirements without stopping the complete production line. LPG or natural gas operation provides flexibility according to the fuel infrastructure available at the installation site, while the independent electrical control panel centralises the main operating controls. The 6mm A3 carbon-steel main structure is intended to support a long industrial installation, while the #430 stainless-steel burner carries an 8-year manufacturer-specified component warranty. Continuous conveying, adjustable operating speed, a broad temperature range and compatibility with two widely used industrial tray formats make the HL-STTO-16 particularly suitable for facilities seeking to increase baking throughput while reducing dependence on manual batch processing.
