When the temperature inside the kettle body 1 exceeds the critical value, the central processing unit 10 cuts off the power to the heating plate 8 and stops heating. When the temperature inside the kettle body 1 is lower than the critical value, the central processing unit 10 powers on the heating plate 8 for heating, which is convenient for temperature adjustment.

A second pressure sensor 13 is fixedly connected to the inner bottom wall of the kettle body 1. The second pressure sensor 13 is connected to the central processing unit 10 by signal. When the pressure value detected by the second pressure sensor 13 is lower than the standard value, it means that the inside of the kettle body 1 needs to be fed. The central processing unit 10 opens the feed valve 6 to automatically feed the inside of the kettle body 1. A control panel 101 is provided on the front of the kettle body 1. A display screen and a timing component are provided on the control panel 101. The user can set the temperature and hydrolysis time on the control panel 101.

[0033] It should be noted that by providing a pressure relief component, it is convenient to monitor the internal air pressure of the hydrolysis kettle in real time and to relieve the pressure of the hydrolysis kettle.

[0034] Specifically, during the production and processing of furfural by the hydrolysis kettle, the air pressure sensor 14 monitors the air pressure value inside the kettle body 1 in real time. When the air pressure inside the kettle body 1 exceeds a critical value, the central processor 10 opens the pressure relief valve 15 to relieve the pressure inside the kettle body 1.

[0035] The working principle of the above embodiment is:

[0036] (1) The hydrolysis kettle for furfural production automatically feeds and discharges materials. During the production and processing of furfural by the hydrolysis kettle, the user sets the temperature and hydrolysis time through the control panel 101. When the pressure value detected by the second pressure sensor 13 is lower than the standard value, the central processing unit 10 opens the feed valve 6, and the furfural production raw materials in the storage box 4 enter the interior of the kettle body 1 through the feed valve 6. When the furfural production raw materials in the kettle body 1 reach the position of the first pressure sensor 7, the first pressure sensor 7 detects the pressure, and the central processing unit 10 closes the feed valve 6 to stop feeding. The heating plate 8 is energized to heat the furfural production raw materials in the kettle body 1, the stirring component 2 stirs the furfural production raw materials, and the steam pipe 3 transports steam to the interior of the kettle body 1 to process the furfural production raw materials in the kettle body 1.
