Most operations and instrumentation in sugar industry are pneumatically controlled. To operate in peak efficiency, clean, dry, compressed air is required. Compressed air cannot be used directly because it contains contaminants like dust, oil, moisture etc. While filters may remove dust and oil, moisture can only be removed by using a Compressed Air Dryer.
Moisture Problems
Sugar is extremely hygroscopic, i.e. it absorbs moisture very quickly. Thus, the moisture must be kept under control at every process during the manufacture of Sugar
Failure to remove moisture from compressed air used for instrumentation typically leads to problems like failure of electro-pneumatic signaling device which in turn results in the valve to ‘fail’ and thus, the whole operation is disrupted.
Apart from problems like malfunctions of instrumentation and control system, production loss due to break downs and increased maintenance costs, and other harmful effect of moisture in compressed air, particularly in the sugar industry in product contamination. Sugar, being a food product, if contaminated, can have fatal effect. Thus, the importance of having clean dry compressed air cannot be overlooked or ignored at any cost.
Another typical problem of sugar Industry arises during the process of sulphur burning. Sulphur reacts with moisture to form sulphuric acid, damaging them irreparably.
The Delair Solution
The only positive means of moisture removal from the compressed air stream is the installation of an air dryer. Water vapour can economically be removed by two methods; one is cooling the air and the other method is by adsorption.
Delair offers a wide range of both refrigeration dryers and adsorption dryers for all your needs.
For general plant and instrumentation air where requirement is between 3°C PDP to 6°C PDP, delair refrigeration dryers, – FDI Series, does the job.
If the application requires extra dry air and PDP below 2°C then delair has a large range of adsorption Dryers – DC Series and engineered systems.
Delair has countless Compressed Air Dryers working in the Sugar Industry to provide moisture free, “bone dry” compressed air for trouble free operation of instrumentation and tools and contamination free sugar.
