4、 Main advantages and features of the equipment:

A、 Mechanical part:

1. The steamer box body is made of 4mm 09CuPNiCr-A weather resistant plate or SUS316L stainless steel plate (depending on customer requirements) and anti-corrosion treatment is carried out on the wall panel to extend its service life.
2. The steam circulation part inside the steamer is made of 09CuPNiCr-A weather resistant plate or SUS316L stainless steel plate (depending on customer requirements), and undergoes anti-corrosion treatment to enhance its corrosion resistance, extend its service life and effectiveness.
3. The roller body with a diameter of 50mm inside the steamer is lightweight and sturdy. It rotates along the track during use to avoid defects such as horizontal marks. And according to different processes and fabrics, three types of hanging rollers can be selected: embedded rubber strip type, four wing type, and fine tooth type.
4. The unique humidification device can be disassembled without shutting down the equipment, cleaning the clogged nozzle of dirt, and easily and quickly restoring it, without affecting production and ensuring product quality in the process.

B: Process humidification and temperature control section:

1. At the feeding loop, there is a unique blowing loop for moisture, and the blowing device directly increases the humidity of the fabric surface, making the color more complete and the loop stable, and can achieve the function of eliminating static electricity;
2. A separate steam spraying device with a large supply of saturated steam is designed directly below the space of about 1 meter in length at the ring forming point, so that the fabric can obtain a large and sufficient amount of saturated steam during the process reaction, making the fabric more fully colored and vibrant;
3. The latest humidification device uses the siphon principle to fully atomize water, and under the action of auxiliary steam, it quickly circulates through the fan and evenly adds it to the steamer, stably controlling the temperature and humidity inside the steamer.

C: Process adaptability section
1. Dispersion process: This machine is equipped with 2 natural gas heating furnaces, with the front one heating the feeding ring box and 2 middle box bodies, and the rear one heating the 2 middle box bodies and the discharging box bodies; Ensure that the temperature inside the steamer is stable and consistent before and after; The temperature difference is extremely small, with a process temperature of ± 1 ℃. The unique ring forming steam humidification makes the hair color more vivid; (Medium pressure steam and heat transfer oil are rolled plate radiators)
2. Active process: On the basis of a constant temperature configuration in the dispersion process, when the active process is rapidly heated to around 102 ℃, the unique saturated steam generator begins to exert its maximum moisture content. The steam with the highest moisture content is uniformly input into the steam box through the circulating fan in the fastest way possible, so that the fabric in the steam box fully absorbs moisture and releases heat at the same time. During the heat release process, the temperature in the steam box rises, and multiple temperature measurement points in the steam box start the humidification device at the same time. The ultra-fine and large amount of steam mist is added to the steam box together under the action of the circulating fan, balancing the set process temperature and keeping the relatively high humidity in the steam box constant; Make the fabric fully colored, with bright and full flower patterns.
3. Carving process: With constant humidity and stable temperature, through unique mechanical design and continuous improvement, the Beifa steamer has broken through the bottleneck of stable processing that only foreign steamers can handle. It truly achieves both single and double frame processing, carving patterns with clear edges, full patterns, realistic colors, and strong three-dimensional sense; Practice has proven that in terms of process stability and quality consistency, it has also reached or even surpassed imported steamers from abroad.
