[0024] As Figure 2 shown, each cup pressure includes a cup pressure cover 23 and a cup pressure rod 24. The cup pressure cover 23 is fixed at the lower end of the cup pressure rod 24 and matches the cup body 20. Small holes are evenly distributed on the cup pressure cover 23.

[0025] The utility model is provided with a PLC touch screen 11 installed on the top plate, which is connected to the first servo motor 1-1 and the second servo motor 1-2 through a PLC controller to realize automatic control of the operation of the servo motors, and controls the entire working process and the working status displayed on the touch screen through the PLC controller; the PLC touch screen 11 is provided with buttons such as "1 group manual / automatic", "2 groups manual / automatic", "1 group sugarcane", and "2 groups sugarcane".

[0026] The utility model can also realize the sliding cooperation connection between the pressing plate and the bracket column by arranging a slide rail on the bracket column and cooperating the two ends of the pressing plate with the bracket column through the slide rail.

[0027] The use method of the utility model bagasse digester is as follows:

[0028] 1. Before using the bagasse cooking device of the utility model, the electric heating device must be started more than 30 minutes in advance to boil the water in the water bath 10, and then the sample is weighed according to the unified analysis method. After adding the specified amount of water, the bagasse cup is placed in the water bath 10 for cooking. At this time, the water level in the water bath 10 should be adjusted to two-thirds of the outer edge of the bagasse cup, so that the cooking state is in the position of half of the steam bath and half of the water bath.

[0029] 2. Follow the instructions on the PLC touch screen 11. If you want to analyze bagasse, place the sample in the front bagasse cup (named "Group 1"), first press "Group 1 Manual / Auto" to switch to automatic, then press Group 1 "Start Bagasse" key to put Group 1 into automatic mode; place the sample in the back bagasse cup (named "Group 2"), first press "Group 2 Manual / Auto" to switch to automatic, then press Group 2 "Start Bagasse" key to put Group 2 into automatic mode. Start timing, and the cooking time enters the setting program. If Group 1 bagasse analysis is selected at this time, Group 1 enters the daily bagasse analysis program. When the time is about to reach 30 minutes, the PLC touch screen 11 issues a command to start the servo motor, and the servo motor drives the piston rod of the electric cylinder to move up and down, and the piston rod of the electric cylinder drives the pressing plate to reciprocate and squeeze the cup 5 times; at 45 minutes, it squeezes up and down 5 times again; when it reaches 60 minutes, repeat the above actions; and an alarm is triggered to remind the analyst that the automatic cooking process has been completed. Take out, cool and weigh, and measure the sugar content. To cancel the alarm, press the PLC touch screen 11.

[0030] 3. If you choose sugarcane analysis, put the sample in group 1 and press the "1 group sugarcane" key, and put it in group 2 and press the "2 group sugarcane" key. It is used for field sugarcane analysis or special analysis. Similarly, when the time reaches 30 minutes, start squeezing (that is, the servo motor drives the piston rod of the electric cylinder to drive the pressing plate to reciprocate and squeeze the cup), and it is performed once every 15 minutes (squeezing 5 times), and the cooking process is a total of 90 minutes, and it is performed 5 times in total.

[0031] By repeatedly squeezing up and down like this, the sucrose in the bagasse can be fully exuded. Take it out, cool it down, weigh it, and conduct a sugar content determination.
