Equipment Description:
- Overall dimensions of the furnace: the total length of the wire body is 9.7 meters, the outer width is 1 meter, the mesh width is 100-500 meters, the total height is 1.5 meters, the length of the discharge belt cold cutting part is 2.5 meters, the length of the drying part is 6 meters, divided into 3 sections, and the length of the feeding and discharging part is 1.2 meters.
- The whole machine shell is high-temperature electrostatic spray painted (not ordinary paint), which has the characteristics of corrosion resistance, wear resistance, rust resistance, non aging, and easy cleaning. The rack design allows for movable casters and foot cups, making it easy to transport and adjust the levelness of the entire machine.
- Furnace body: The inner liner has 3 furnace chambers, each section is 2.0 meters long, with a total length of 9.7 meters. The inner liner material is made of SUS # 202 stainless steel plate, with a height of 0.20 meters in the furnace chamber and a net height of 0.10 meters at the feeding port. It is equipped with an adjustable baffle plate, with a 100mm thick high-temperature silicate insulation rock wool in the middle. The bottom of the mesh belt is equipped with a high-temperature insulation layer to prevent the outside of the furnace from getting hot. The bottom is equipped with a ventilation motor to make the temperature more uniform. Each section of the furnace cover can be opened independently for easy cleaning and maintenance inside the furnace. High temperature silicate insulation rock wool is laid in the middle of each section of the furnace cover, and high-temperature resistant sealing silicone is added around it to achieve good sealing effect, avoid unnecessary heat loss, make the temperature outside the furnace not hot, and the insulation effect inside the furnace is good.
- Heating system: Using the latest cutting-edge technology of high-tech materials - infrared heating tubes, with the characteristics of fast heating speed, far-infrared radiation penetrating the workpiece, and thermal energy reflection, the principle of thermal conductivity, converts electrical energy into thermal energy.
- Control section: The temperature of each section can be independently controlled and displayed. The temperature control system is equipped with PV and SV digital display windows, and the output is controlled by a thyristor rectifier. The output power can be automatically adjusted according to the error size of the temperature to make the temperature more accurate. The dual temperature controller is equipped with an over temperature upper limit temperature controller to prevent damage to the product due to the main temperature controller losing control. The functions include PID self-tuning calculus control, automatic constant temperature, over temperature alarm, leakage protection, motor overload protection, etc; Equipped with an emergency stop button to ensure safety.
- Transmission part: Double pitch quarter roller chain with triangular aluminum support rod installed.
- Air duct design: Design an air pressurized return air duct, where the air is circulated and heated before being drawn into the furnace by a fan, allowing hot air to dissipate throughout the tunnel furnace and preventing cold air from entering the furnace, thus achieving the goal of energy conservation. The double inner layers of the furnace cover are equipped with air ducts, and a diversion plate adjustment device is designed to make the temperature inside the furnace more uniform; Each furnace chamber is equipped with an independent temperature control system, making it convenient to set different temperatures.
- The furnace cover is opened by a cylinder on one side or lifted by four corners.
- Exhaust system: A diagonal exhaust plate is designed at the discharge port to prevent cold air from entering the furnace and hot air from being discharged from the furnace, thus ensuring the storage of heat.
- Heating device: The heating tube is installed above the conveyor belt, and the installation height of the heating tube can be adjusted according to the height of the baked goods (adjustment range 0-150mm), thereby reducing the baking space and achieving energy-saving and energy-saving effects. And each heating tube is equipped with thermal energy reflective materials, which have the functions of reflecting light, heat energy, and heat accumulation. The system has a thermal energy utilization rate of over 30%.
11 . Cooling system: Design an air cooling device in the discharge area with double-layer cooling. |
