The device uses highly efficient ceramic corrugated packing. The distillation column body is made of stainless steel, thus preventing the iron filings from filling the filler and prolonging the service life of the device. All parts of the device that come into contact with alcohol, such as condensers, surge tanks, and cooling coils, are made of stainless steel to ensure that the finished alcohol is not contaminated. The W-type distillation kettle adopts a detachable U-shaped heating tube. During the inspection, the U-shaped heating tube can be moved out of the kettle to facilitate the cleaning of the outer wall of the heating tube and the inner wall of the distillation kettle.
       The ZW type eliminates the need for an indirect heating still. Condenser tube heat exchanger, but also according to user requirements to supply spiral plate heat exchanger, cooler coil cooler, using coil cooler and matching supply tank and specific gravity measuring device.

Uses:
        This device is suitable for the recovery of diluted alcohol in pharmaceutical, food, light industry, chemical industry and other industries. Also suitable for the distillation of other solvents such as methanol. According to the user's requirements, this device can dilute about 30° dilute alcohol to 90-95° alcohol. The higher the alcohol requirement of the finished product, the larger the reflux ratio can be, but the output is reduced accordingly.

Device composition:
        W-type has five kinds of specifications, each specification includes the corresponding configuration of steam distillation tower, distillation kettle, condenser, cooler, regulator tank, specific gravity measuring device. Among them, the W-200 and W-300 distillation towers are installed directly on the distillation still. The W-400, W-500, and W-600 distillation columns were installed separately from the distillation stills.
        ZW-type ZW-200, ZW-300 two specifications, each specification includes the corresponding supporting preheater, distillation tower, condenser, cooler, regulator tank, specific gravity measuring device.
        Other auxiliary equipment and instruments such as metering tanks, storage tanks, transfer pumps, rotameters, temperature indicating instruments, etc. are provided by the user. Our factory can also provide additional processing or ordering and supplying according to user requirements.

Technical parameters:
       ■ Feed concentration 30%～80%
       ■Feeding concentration: 90%～95%
       ■Reflux ratio: R=13 (according to inlet and outlet material concentration )
       ■ Residue discharge containing alcohol concentration: W type ≤3% , ZW ≤ 1%
       ■ Production capacity (kg/h): see table
