Constant drying rate equation
WebFeb 12, 2024 · The general rate law is usually expressed as: Rate = k[A]s[B]t. As you can see from Equation 2.5.5 above, the reaction rate is dependent on the concentration of the reactants as well as the rate constant. However, there are also other factors that can influence the rate of reaction. WebDrying is a mass transfer process consisting of the removal of water or another solvent [1] by evaporation from a solid, semi-solid or liquid. This process is often used as a final production step before selling or packaging products.

WebJun 20, 2024 · Drying rate can be calculated by two ways. These are the equations I found in literature for calculating the constant drying rate for flash/pneumatic drying. (Free moisture is only evaporated. particle temperature normally doesn't exceed 50 Celsius) w = drying rate (kg/ m2 s) k = mass transfer coefficient. Ts = Solid temperature = 303 K = 30 C. Webvalidated by drying unripe plantain chips in a batch dryer at air velocities between 0.66 and 1.20m/s at corresponding temperatures between 42 and 66oC. Based on the analogy of heat and mass transfer rate equations for constant drying period, the prediction from the developed model agreed reasonably with the experimental data.
