The syrup (or molasses) is concentrated to a certain saturation in the boiling sugar tank, and the sucrose crystals that meet the requirements are precipitated and the crystals are raised to make a good sugar pasteThe mother liquor is discharged through the crystallization and centrifuge to obtain good crystalline granulated sugar, and the whole operation process is to boil the sugar. Most of the sugar tanks in China's sugar factories are carbon steel structures, at the beginning of a new crushing season, they must be cleaned and rusted, in addition, during the use of the sugar tanks, a layer of sugar paste will be attached to its inner wall, and the residual sugar paste needs to be cleaned up regularly.
At present, most of the domestic sugar factories are still using traditional manual operations, which is not only time-consuming and time-consuming, but also has a great labor intensity, and the tank wall is thinned year by year due to corrosion, which seriously affects the service life, and the production cost is also increased accordingly. And manual brushing of the boiled sugar tank, easy to cause scratches to the tank, for this reason, we have gone through a lot of tests, and finally recommend the use of DP 400 45EM high-pressure cleaner to solve the problem of rust removal of the boiled sugar tank, the equipment pressure is 400bar, the flow rate is 45L min, the cleaning pressure is adjustable, can work continuously for a long time, and has water shortage safety protection, the operation mode is through manual handheld high-pressure water gun operation, with high efficiency, high quality, pollution-free, low cost, The characteristics such as not damaging the object to be cleaned are explained in detail below.
Normally, the high-pressure pump completes a suction and discharge process of water, and sends a certain amount of water to the high-pressure pipeline, so that it reaches the nozzle with a certain energy, and the aperture of the nozzle is much smaller than the diameter of the high-pressure pipeline, so the amount of water that reaches the nozzle must be accelerated if it wants to flow out of the nozzle hole. In this way, the water that accelerates through the nozzle orifice to condense at an accelerated rate forms a jet. When the high-pressure water jet is continuously sprayed to the scale layer, the energy is transmitted to the scale layer intensively, and the scale layer is broken down, so that the phenomenon of "dripping water through the stone" that can only be observed with perseverance can be completed in an instant. Because the high-pressure water jet has the composite crushing effect of scouring, wedge, shearing, grinding, etc., the scale can be broken and washed away immediately, so as to realize the separation of the scale layer and the pipe wall. Therefore, it is several times to dozens of times faster than the traditional simple mechanical and manual cleaning methods.
Let's take a sugar factory in Guizhou as an example, at first, the factory used manual beating to remove rust from the boiled sugar tanks, and it took 4 to 5 people to clean only one boiled sugar tank, and it took a whole day. Since the DP 400 45EM high-pressure washer was used, only 2 people were required to cooperate with the operation, and the entire rust removal operation could be completed in one and a half hours, which greatly saved labor and operation time. And because the high-pressure water jet can shoot to the dead corners such as the juicer and the bottom of the tank that cannot be reached by manual rust removal, the rust removal effect is very good. In addition, manual knocking to remove rust is very harmful to human health, while using DP 400 45EM high-pressure cleaner to remove rust is harmless to the human body.
To sum up, we can see that the use of DP 400 45EM high-pressure cleaner to remove rust can save a lot of manpower and time, is a simple and effective way to reduce the insoluble content of white sugar water, reduce the output of unqualified sugar, in addition to the 400bar high-pressure cleaner can meet the cleaning of dirt on the surface of equipment, such as for the surface of the heat exchanger in sugar factories.
