What are the reasons for the poor sugar extraction rate in sugar extraction equipment?

1. The pressing efficiency is generally measured by the processing capacity and extraction rate of the sugar pressing equipment.

Generally speaking, under certain conditions of sugar extraction equipment, if the extraction rate is to be increased, the extraction rate will often decrease. On the contrary, if the extraction rate is to be increased, the extraction rate will be affected, so the processing capacity and extraction rate are contradictory and mutually restrictive. , Comprehensive consideration, setting a suitable pressing speed not only requires a certain amount of pressing, but also does not cause the extraction rate to be too low.

2. The fiber in the sugarcane expands when it leaves the outlet of the press after being compressed. At this time, the compressed fiber will absorb a part of the sugarcane juice that has been squeezed at the outlet with its own expansion. It is impossible to squeeze out all the sugar in the press. The technical principle of "increasing the load of the front roller to reduce the load of the whole machine to improve the pressing efficiency" is adopted to change and reduce the opening and opening ratio of the front and rear rollers of the press to improve the juice yield of the front roller. The pressure of the roller to discharge the juice can reduce the re-suction and the water content of the bagasse, so as to achieve the ultimate goal of improving the extraction rate of the single machine and the whole machine row and reducing the energy consumption of the press machine.

3. The crushing degree and shape of the sugarcane material are also the premise to ensure the extraction of the primary press. The sugarcane has a good degree of fragmentation, the juice can be easily squeezed out, and the extraction rate will increase. Of course, there are certain requirements for the sugar extraction equipment.

4. The uniform thickness of the sugarcane layer conveyed from the sugarcane conveyor is very important to improve the extraction rate. If the cane layer is too thick, the pressing is not clean; if the cane layer is too thin, the cane layer cannot be pressed, both of which will affect the extraction rate.

5. As the wear of the press roll becomes more and more serious, the gap of the press roll expands and the extraction rate decreases.
