Technical description • Model / internal code: HL-DTTO-09. • Equipment type: industrial continuous gas tunnel oven for bakery and food production. • Configuration: double tray line. • Total length of commercial configuration: 9m. • Baking area of commercial configuration: 7m. • Continuously adjustable conveyor speed: 240–1200mm/min. • Adjustable baking time: 5–25 minutes. • Temperature range: 25–350°C. • Fuel: LPG or natural gas. • LPG consumption: 3.5kg/h. • Natural gas consumption: 4.5m³/h. • Electrical supply: 380V, 50Hz, three-phase. • Specified electrical power: 3kW. • Exterior cladding in 1.5mm SS201 stainless steel. • Baking chamber interior in 0.8mm aluminised steel plate. • 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. • Gas regulator box. • Independent electrical control panel. Commercial description The Hongling HL-DTTO-09 is an industrial continuous gas tunnel oven designed for industrial bakeries, baked-goods factories, pastry production plants, prepared-food manufacturers and food-processing lines requiring a continuous baking process. Its double-tray-line configuration provides two product positions across the conveying system, making it suitable for facilities seeking increased processing surface without relying on a longer single-line tunnel oven. The commercial configuration has a 9m total length and 7m baking area. Conveyor speed can be continuously adjusted between 240 and 1200mm/min, allowing product residence time inside the oven to be adapted between approximately 5 and 25 minutes according to recipe, product thickness and required baking conditions. Its 25–350°C operating range supports different bakery, pastry and baked or pre-cooked food applications. The oven is particularly suitable for continuous processing of empanadas, laminated pastries, bakery products, savoury pastries, bread, biscuits, pre-cooked foods and other products compatible with tray-based baking, subject to the tray dimensions and final production configuration selected for the installation. The system can operate with LPG or natural gas, providing flexibility according to the fuel infrastructure available at the production facility. Specified consumption is 3.5kg/h for LPG or 4.5m³/h for natural gas, while the electrical system operates from a 380V/50Hz three-phase supply. Its construction combines a 6mm A3 carbon-steel main structure, 1.5mm SS201 stainless-steel exterior cladding and 0.8mm aluminised plate inside the baking chamber, using different materials according to the function of each section. The #430 stainless-steel gas burner carries an 8-year manufacturer-specified component warranty. The combination of a double tray line, continuous conveying, adjustable speed, broad temperature range and dual-gas capability makes the HL-DTTO-09 particularly suitable for operations seeking to maintain a stable flow of trays, adapt baking time to different recipes and reduce dependence on manual batch processing.
