SHX Three-Layer Oil/Gas-Fired Oven: Extended Hot Air Circulation Drying Equipment

The SHX three-layer oil/gas-fired oven is used for drying various puffed snack foods and semi-puffed food doughs.The equipment employs a three-layer stainless steel mesh belt for reciprocating conveying. Utilizing heat from the combustion chamber in conjunction with circulating fans to create a hot air circulation system, it enhances material capacity and drying uniformity within a compact footprint.The equipment supports variable frequency speed control, allowing the conveying speed and drying temperature to be set according to the characteristics of the material.

Main Technical Parameters

The net belt transmission drive power is 1.1 kW, the circulating fan drive power is 4 kW, and the burner drive power is 0.11 kW.Equipped with a Buderus BTG-11 burner, thermal power 48.8-99kW, can use methane gas or liquefied petroleum gas.Heating temperature ranges from room temperature to 250°C, with a mesh belt effective length of 18 m and width of 1 m. Overall dimensions are 9000×1500×2500 mm.

Installation and Drying Control

The equipment should be installed on a well-ventilated, dry, level, and sturdy floor, with the suction duct, pneumatic conveying machine, and exhaust chimney properly connected.Check the safety status of the mesh belt, waste box, drive system, and burner under no-load conditions. Start the circulation fan before igniting the burner to prevent excessive combustion in the combustion chamber.In actual production, snacks can be dried within a temperature range of 120–150°C in approximately 5–10 minutes, with product moisture content adjusted by coordinating the mesh belt speed and temperature control settings.

Safety and Maintenance

The oven is a high-temperature device; the observation door must not be opened during operation. Before addressing any abnormalities, turn off the heat source and allow the oven to cool.Clean the bottom waste box every 2-3 hours. Do not store flammable or explosive materials around the oven.Regularly inspect the sealing of gas pipelines, the tension of mesh belt chains and V-belts, and replace the reducer's lubricating oil according to the scheduled intervals.
