[0031] In this embodiment, the liquid inlet pipe 5 is located at the lower end of the side of the jacket 2, and the liquid inlet pipe 5 transversely penetrates the jacket 2 and extends to the lower end of the interior of the kettle body 1. The cooling liquid can pass from the liquid inlet pipe 5 into the lower end of the liquid outlet pipe 6 inside the kettle body 1, and then enter the bottom of the condenser 7 from the lower end of the liquid outlet pipe 6, so that the cooling water enters at the low end and exits at the high end.

[0032] In this embodiment, the liquid outlet pipe 6 is vertically arranged, and the liquid outlet pipe 6 vertically penetrates the kettle body 1 and extends inward to the lower end of the inner part of the kettle body 1. The vertically arranged liquid outlet pipe 6 can allow the incoming cooling liquid to enter the condenser 7 downward and flow downward from the bottom of the condenser 7, thereby filling the condenser 7 from bottom to top and exchanging heat with the liquid in the kettle body 1. By arranging the condenser 7 inside the kettle body 1, the heat exchange area of ​​the unit kettle body can be increased, the temperature process requirements of the product can be effectively controlled, the heating or cooling operation can be completed in time, and the quality of the product can be guaranteed.

[0033] In this embodiment, the condenser 7 is installed on the left and right sides of the inside of the kettle body 1 through the liquid inlet pipe 5 and the liquid outlet pipe 6, and the condenser 7 is vertically arranged. The vertically arranged condenser 7 can fully contact the liquid in the kettle, ensuring the contact area between the condenser 7 and the liquid in the kettle, thereby ensuring the heat exchange area of ​​the condenser 7.

The liquid outlet pipe 6 vertically penetrates the condenser 7 and is connected to the upper and lower ends of the condenser 7. The cooling liquid can pass from the liquid inlet pipe 5 into the lower end of the liquid outlet pipe 6 inside the kettle body 1, and then enter the bottom of the condenser 7 from the lower end of the liquid outlet pipe 6.
