__________ was used to describe relationship between the water activity and equilibrium moisture content.

__________ was used to describe relationship between the water activity and equilibrium moisture content. Correct Answer GAB model

GAB modelwas used to describe relationship between the water activity and equilibrium moisture content. In Guggenheim, Anderson, de Boer (GAB) model, the sample is kept in the desiccators which contains saturated Potassium nitrate solution to maintain the relative humidity at 90% at 40°C and are kept in a temperature controlled chamber. Moisture content and water activity of each sample is determined using hot air oven and water activity meter.

200 kg of solids (on dry basis) is subjected to a drying process for a period of 5000 seconds. The drying occurs in the constant rate period with the drying rate as, Nc = 0.5 × 10-3 kg/m2.s. The initial moisture content of the solid is 0.2 kg moisture/kg dry solid. The interfacial area available for drying is 4 m2/1000 kg of dry solid. The moisture content at the end of the drying period is (in kg moisture/kg dry solid)
In a laboratory test run, the rate of drying was found to be 0.5 × 10-3 kg/m2.s, when the moisture content reduced from 0.4 to 0.1 on dry basis. The critical moisture content of the material is 0.08 on a dry basis. A tray dryer is used to dry 100 kg (dry basis) of the same material under identical conditions. The surface area of the material is 0.04 m2/kg of dry solid. The time required (in seconds) to reduce the moisture content of the solids from 0.3 to 0.2 (dry basis) is
