Sugar Storage

Moisture Solution for Sugar Industry from Bry-Air

Dehumidification Drying

Sugar is extremely hygroscopic, i.e. it absorbs moisture very quickly, creating innumerable operational problems during storage and packing. Refined sugar is fed via belt conveyers to sugar bins or hoppers. At this point the sugar is at about 48°C (118°F) with moisture content approximately 0.035% of its weight. This sugar, however, has to be cooled to about 38°C (100°F) to 40°C (104°F) before it can be packaged. If cooled by the conventional method, the cooling process takes about 12 hours during which condensation takes place on the bin ceiling. This results in lumping of the top layer and deterioration in quality .

Moisture Problems during conveying

  • Moisture absorption while conveying affects the final product and spoils the material
  • It inhibits the smooth transfer of sugar.
  • It corrodes the equipment.
  • Maintenance related downtime.
  • Flow is hindered because of agglomeration
  • Sanitation problems.

It is generally recommended that during conveying the RH be maintained at < 40%.

Moisture Problems during storage

Sugar becoming sticky during storage is if proper conditions are not maintained is a common problem. Moisture also causes mold growth and ultimately spoilage. Condensation inside silo leads to corrosion and so to increased maintenance costs.

Surround sugar with dry air during conveying and storage

Moisture control protects equipment from corrosion even during idle months

Steel starts to corrode if the relative humidity is above 60%. So even during the idle months the machinery of sugar refineries have to be kept in properly dehumidified conditions. Machinery in the sugar refinery can be kept free from corrosion even during the non operational months through proper dehumidification.

Bry-Air Dehumidifiers for sugar that does not lump, stick or cake

Bry-Air Desiccant Dehumidifiers can effectively maintain the most stringent humidity conditions required for sugar storage and packaging since they are capable of maintaining RH as low as 1% or even lower at a constant level, regardless of ambient conditions.

Bry-Air has a large range of standard as well as engineered dehumidifiers which are packaged to ensure dry packaging of sugar whether in sachets or in cubes.

 

Now you too can install a Bry-Air Dehumidifier and be one-up on your competitors.
