Natural gas direct combustion two-side hot air circulation network belt dryer
The natural gas direct-fired double-side hot air circulation net belt drier (patented product) is a new type of nut stir-fry drier developed and successfully developed by our company in China in 2014. In recent years, combined with the characteristics of drying nuts in China, the company has cooperated with foreign famous heater companies and made continuous improvement, making this dryer far ahead of other similar products at home and abroad in performance and energy consumption.
1. Reasonable air distribution and uniform temperature. By adopting double-side inlet air, hot air is blown in from both left and right ends of the box, enabling the material to be dehydrated evenly. With multi-layer design, the material can be turned over to achieve the same rate of dehydration of the material.
2. Advanced and scientific design is highly efficient and energy-saving, with energy consumption lower than 25% of similar domestic and foreign equipment; The output is 30-40% higher, and the overall performance is better than similar equipment at home and abroad.
3. Unique air and gas mixture design, natural gas combustion efficiency is close to 100%, reaching the minimum energy consumption;
4. Direct combustion of natural gas is efficient and energy-saving. No need of heat exchanger, boiler purchase, installation and operation to effectively reduce equipment operation and investment cost;
5. Clean combustion tail gas, produce melon seed sample to detect sulfur dioxide 0 residue, and ensure the quality of dry food;
6, warming faster, from room temperature to 120 ℃ only need 3-4 minutes; Fast thermal compensation is conducive to the adjustment of temperature in the drying process; Short preheating time effectively solve the problem of high cost in off-season production;
7. Accurate temperature control. Almost zero error between actual production temperature and set temperature;
8. Circulating use of hot air, low energy consumption, and effectively reduce equipment operating costs;
9. The equipment is provided with safety interlock device -- gas low-pressure interlock, high-temperature protection interlock, flame detection and other safety interlock devices, so as to make the operation of the equipment safer and more reliable;
10. This equipment is a dual-use type of thermal oil and natural gas. If the customer changes the heat source from thermal oil to natural gas direct combustion, it only needs to install gas device.
A. Moisture content of the supplied material >45% + / - 5
B. Moisture content of finished products < 3%
C. Thermal natural gas, thermal oil, steam
D. the drying temperature 40 ℃ ~ 220 ℃
Scope of application: drying of sunflower seeds, watermelon seeds, peanuts, pumpkin seeds, pecans, almond nuts, macadamia nuts, bigan nuts and other nuts, food, grain, oil, potato chips and other materials.
The sulfur dioxide residue was detected by the direct combustion net-belt drying machine. As the combustion efficiency is close to 100%, the exhaust emission is pure and the food safety is guaranteed
Measured production cost comparison (melon seeds) : the drying cost was 0.09--0.11 yuan /500g, and the equipment of other manufacturers saved 0.11 yuan /500g or more on a year-on-year basis. The output increased by 30-40% on a year-on-year basis by 15 tons per day, saving 3,300 yuan per day. (3 yuan for natural gas /m cubed)
