Example Embodiment
[0026] Example 1
[0027] A sugar clarification production line, including a mixed juice box 3, a decanter centrifuge 4, a first heating device, a sulfur fumigation device, a second heating device, a multi-stage ceramic membrane ultrafiltration system 16 and a plate and frame filter press which are connected in sequence 机18.
[0028] A first buffer box 5 is connected between the decanter centrifuge 4 and the first heating device, a second buffer box 11 is connected between the sulfur fumigation device and the second heating device, the second heating device and the multi-stage ceramic membrane A third buffer tank 15 is connected between the ultrafiltration systems.
[0029] The inlet of the mixed juice box 3 is connected with the squeezing and extracting section 1 of the sugar cane sugar factory and the lime milk tank 2. The outlet of the mixed juice box 3 is connected with the inlet of the horizontal screw centrifuge 4, and the outlet of the horizontal screw centrifuge 4 is connecte...
Example Embodiment
[0035] Example 2
[0036] This example is an example of actual production using the sugar clarification production line described in Example 1. The specific operation steps are as follows:
[0037] (1) Ashing: add 8.0°Be lime milk to the mixed juice of the sugar cane sugar factory, adjust the pH value of the sugar cane juice to 7.6, prevent the sucrose in the sugar cane juice from transforming under acidic conditions, resulting in the loss of sucrose. Add gray sugarcane juice;
[0038] (2) Coarse filtration: Use a horizontal screw centrifuge with a pore size of 50.0μm to filter the ashed sugarcane juice to obtain coarse-filtered sugarcane juice;
[0039] (3) The first heating: use a tubular heat exchanger to heat the coarsely filtered sugarcane juice to 55°C, which is conducive to the effect of the sugarcane juice on SO in the next sulfur fumigation process. 2 The absorption of sugarcane juice for the first time;
[0040] (4) Sulfur fumigation: Use a sulfur fumigation device to perform...
Example Embodiment
[0052] Example 3
[0053] This example is another example of actual production using the sugar clarification production line described in Example 1. The specific operation steps are as follows:
[0054] (1) Ashing: add 8.5°Be lime milk to the mixed juice of the sugar cane sugar factory, adjust the pH value of the sugar cane juice to 7.5, prevent the sucrose in the sugar cane juice from transforming under acidic conditions, resulting in the loss of sucrose. Add gray sugarcane juice;
[0055] (2) Coarse filtration: use a horizontal screw centrifuge with a pore size of 150.0μm to filter the ashed sugarcane juice to obtain coarse-filtered sugarcane juice;
[0056] (3) The first heating: use a tubular heat exchanger to heat the coarsely filtered sugarcane juice to 65℃, which is conducive to the effect of the sugarcane juice on SO in the next sulfur fumigation process. 2 The absorption of sugarcane juice for the first time;
[0057] (4) Sulfur fumigation: Use a sulfur fumigation device to pe...
