What should be paid attention to when using radar level gauge in starch production?

Starch is no stranger, it is an additive in many industries, such as pharmaceutical industry, food industry, etc. For the production of such a substance, would a radar level meter be used?


In the production process of starch, there is a necessary process, namely "soaking". Grain is removed from the husk by soaking, and the husk can be used as an animal feed additive after drying. In large starch factories, large quantities of corn and wheat need to be processed every year, and the chaff needs to be stored in silos before going to the next process. In order to continue production and avoid interruptions, continuous monitoring of grain stocks by instruments is required. Therefore, starch production requires level measuring instruments such as radar level gauges.


Since it is necessary, what working conditions need to be paid attention to when the radar level gauge is used in such occasions?

First of all, chaff, also called bran, is a low-reflection medium, and there will be condensation and dust on its surface. When choosing a radar level gauge, pay attention to the influence of condensation water and dust on radar waves.

 

There was a company that used a radar level gauge with a horn antenna in the bran warehouse. As a result, the antenna head needs to be cleaned regularly. Not to mention the time spent, the cleaning production must be interrupted, which is a huge loss for the company.

 

From this case, it is not difficult to see that if you want to avoid the above problems, you need to choose a suitable radar level gauge, which is not affected by dust and condensed water as much as possible, and is maintenance-free or less maintenance.

 

Secondly, the grain is stored in the barn, and the surface will be uneven due to unevenness, which will also have a certain impact on the radar level gauge, which should also be paid attention to.

 

For the case of uneven interface, FM radar level gauge can be selected. FM radar level gauge has higher frequency, smaller launch angle, more concentrated energy, and stronger echo signal.

In starch production, there are many places where radar level gauges are used. When choosing, you can choose a suitable model according to the actual working conditions, so that you can save costs on the premise of improving production efficiency.
