The problems related to product drying are typically : Quality of Drying & Speed of Drying Conventionally; products are dried with hot air. However, most products, which require drying, are temperature sensitive. We are amongst the reliable Providers of the Dehumidifiers. Our Dehumidifier is appreciated for ease-of maintenance and high power efficiency.
Moisture is present in the products as : Free moisture in form of surface moisture generated due to washing or mixing the product with water prior to drying; Hygroscopic moisture which is held within the product; or a combination of both. Drying operations involve the removal of all moisture to the required level. Surface moisture (and it is often assumed that it is only type of moisture present) is conventionally removed by raising the product temperature by using hot air to vaporize the moisture. However this can result in product spoilage as many products like cocoa, gelatin, coffee etc. are temperature sensitive and need to be dried at low temperature. Proper removal of the hygroscopic moisture depends on the difference between the relative humidity of the air surrounding the product and of the product's equilibrium condition. If the RH of surrounding air is lower, then the product will give up its hygroscopic moisture to the drier air to be in equilibrium with its surrounding velocity of the air over the product has little or no bearing on the drying speed.
Product Drying application are typically
Bulk (Batch) drying when material is loaded into a compartment and entire load is dried as a batch. Continuous drying is when the wet material continuously is fed into the drying room/chamber and it leaves the chamber, dried to the desired result.
As every material has different physical characteristics, with determine how it holds or gives up moisture, and published air-drying equipment must be done experimentally. Usually the sudden change in drying rate (at the critical point) donates where the initial drying via removal of free moisture ends, and hygroscopic drying takes place over. In other words, the product has lost its free moisture but is still hygroscopically saturated. However the net effective drying surface and hygroscopic properties cannot be determined in any of the way.
Advantages : Dehumidification is the most cost effective and easy method to ensure drying without spoilage as the drying is based on the difference in vapor pressures of water in the product and the surrounding air. By physically removing the moisture from air, through the condensation the evaporative potential of the air is maximized.
