WX-SJ series Tunnel Pasteurizer is also called water spraying type bottle warming/cooling machine. Different from directly heating type flash sterilizing machine, this series tunnel pasteurizer could sterilize liquid product together with its package (glass bottle or can). It can kill mostly all bacteria which possible exist in liquid product or package. Liquid product and its package are heated to sterilizing temperature, keep this temperature for a certain time, and then drop temperature to surrounding temperature by spraying cool water onto package. Containers and the inclusion is heated to the required sterilization temperature and maintained at that temperature for some time, and then down to ambient temperature. This machine contains 8 temperature zones, the minimum temperature difference between zones confirms good sterilizing effect, and also reduce bottle broken rate. Hot water is recycled to use in temperature sections in order to save heat energy and reduce water consumption.

This Tunnel Pasteurizer mainly consists of three sections: heating section, constant temperature section and cooling section. Can input conveyor transfers full bottles onto mesh belt from bottle input conveyor. All bottles in the machine are arranged in order and pass through three sections one by one, and achieve requirements of processing technology. At last, bottle output conveyors transfer bottles to discharging chain. Following is description about three sections on: used for bottles and cans.
