The water in the scraper evaporator has to be continuously cooled. Under our long-term operation, there will be some microorganisms and corrosive substances in the water. This is because we have not treated the water, so the copper pipe There will be some dirt on the inner wall, which will affect our heat transfer and may damage the entire machine over time.
The common solution is chemical method, which is to pickling the scraper evaporator, which is more convenient and short, but it is easy to have corrosion. Of course, we can also use cleaning agents, which can decompose the organisms in the water, and of course can treat the dirt in the water. Not only can it be used directly, but it can also be diluted, but the cost is also relatively high.
In daily use, if you do regular cleaning and maintenance work, you can reduce the appearance of scaling on the scraper evaporator. If there is a mistake in cleaning and maintenance and scaling occurs, don't worry, the problem can be solved by the method described above.
In addition to performance, energy consumption is another concern of scraper evaporators, because in actual use, the energy consumption of evaporators has always been very high, occupying a large part of the finished product. There is a reason why the energy consumption of the scraper evaporator is relatively high. On the one hand, the evaporator itself is an energy-efficient configuration that requires a certain amount of energy to ensure its normal operation.
On the other hand, it may also be caused by the increase in the efficiency of the evaporator. After the evaporation process is developed and used, the supporting evaporation equipment must be strengthened. The basis for achieving this goal is the consumption of more energy. .
On the other hand, it is related to the problems of the scraper evaporator itself. For example, the evaporator is not properly maintained, and the internal structure of the heating tube is serious, which reduces the heat transfer coefficient. Therefore, in order to reach the temperature required by the process, it can only be achieved by increasing the heating time. In this way, more energy will naturally be consumed.
