Tests were conducted to determine the effects of drying conditions on the rate of fissure formation after drying and the resultant mechanical strength distributions of individual rice kernels. Long-grain varieties Cypress, Drew, and Wells at 21% harvest moisture content (HMC) were dried at 40°C, 45°C, 50°C, 55°C, and 60°C and constant 17% relative humidity (RH) to 12% MC. Immediately after dryi...

Spirals as internals are utilized to reduce the axial mixing of solids in fluidized beds, by routing the solids flow in a predetermined route or by localizing the solids mixing. The drying kinetics of continuous fluidized bed with and without internals has been compared and modeled using batch drying kinetics and residence time distribution analysis. The batch drying experiments were conducted ...

in this research the thin layer drying behavior of apricot (cv. ghavami and nasiry) at temperatures of drying air of 40, 50, 60 and 70 ºc and at drying air velocity of 2 ms-1 was studied. in order to select the best drying curve equation, 9 different thin layer drying models were fitted to the experimental data and were compared according to their coefficient of determination (r2), reduced chi-...

The influence of granulometric properties of the material and of the operational conditions on the drying kinetics of nonhygroscopic material was studied. Four fraction sizes of dolomite were chosen and dried in four dryers by different heating methods. Dolomite was dried in a microwave dryer under different microwave heating powers. During convective drying the effects of temperature and super...

with considering importance of post harvest operation on quality criteria of pot marigold (calendula offıcinalis l.), the effect of flower nutrient source (organic inputs such as cattle manure (25 t ha-1), municipal waste compost (20 t ha-1), spent mushroom compost (15 t ha-1), vermicompost (15 t ha-1) and control) as well as different drying methods including microwave (300, 600 and 900 w), ov...

Soil nitrogen is one of the crucial components for plant growth. An accurate diagnosis based on soil nitrogen information is the premise of scientific fertilization in precision agriculture. Soil nitrogen content acquisition based on near-infrared (NIR) spectroscopy shows the significant advantages of high accuracy, real-time analysis, and convenience. However, soil texture, soil moisture conte...

This paper describes an experimental investigation of the drying behavior and conditions of rosehip in a convective cyclone-type dryer. Drying experiments were conducted at air inlet temperatures of 50, 60 and 70 o C and air velocities of 0.5, 1 and 1.5 ms. The parametric values obtained from the experiments were fitted to the Newton mathematical models. Consequently, the drying model developed...

Freeze drying (FD) yields the best quality of dried sea cucumber but at the cost of long drying time and also the overall cost. Air drying (AD) gives an unacceptably poor quality product. To achieve faster drying along with a high quality product a microwave freeze drying (MFD) technique was developed to dry sea cucumbers. The relationship between corona discharge and microwave power at various...
