[0027] The connecting pipe 13 passes through one side of the evaporation tank 1 and extends to the interior of the evaporation tank 1. The connecting pipe 13 is connected to the interior of the condensing coil 8.

[0028] The liquid outlet valve 6 is connected to the interior of the condensing coil 8, and the water inlet pipe 11 is fixedly connected to the condensing bin 12;

[0029] The water inlet pipe 11 is connected to the interior of the condensation chamber 12, and the input end of the water pump 10 passes through the top of the cold water tank 5 and extends to the bottom end of the interior of the cold water tank 5;

[0030] Specifically, if Figure 1 and Figure 2 As shown, during the processing, the steam inside the evaporator 1 enters the interior of the condensing coil 8 through the connecting pipe 13, and the electric control valve 19 is started to extract the cold water inside the cold water tank 5 and introduce it into the interior of the condensing bin 12 through the water inlet pipe 11. After the cold water enters the interior of the condensing bin 12 and flows through the outside of the condensing coil 8, it can quickly exchange heat with the steam inside the condensing coil 8, thereby cooling and liquefying the steam. After that, the liquid outlet valve 6 is opened to collect it, and the cooling water flows back to the interior of the cold water tank 5 through the return pipe 7 to realize circulation, thereby realizing rapid cooling of the steam.

[0031] Example 2: The top of the evaporator 1 is fixedly connected to a drive motor 16, the top of the interior of the evaporator 1 is fixedly connected to a fixed sleeve 15, the interior of the fixed sleeve 15 is movably connected to a rotating shaft 14, the bottom end of the rotating shaft 14 is fixedly connected to a connecting arm 24, both sides of the connecting arm 24 are fixedly connected to scrapers 22, the bottom end of the evaporator 1 is fixedly connected to a discharge port 23, and the interior of the discharge port 23 is movably connected to a bottom cover 25;

When the material volume reaches the specified height, the liquid level sensor 21 transmits a signal to the controller 17, and the controller 17 closes the electric control valve 19 through the connecting line 18. After the electric control valve 19 is closed, the feeding is stopped. At the same time, the electric control valve 19 can be started at a time on the controller 17, so as to automate the feeding for continuous processing. During the processing, the steam inside the evaporation tank 1 enters the interior of the condensing coil 8 through the connecting pipe 13, and the electric control valve 19 is started to extract the cold water inside the cold water tank 5 and introduce it into the condensing coil through the water inlet pipe 11.
