In order to imitate biological gait subtly and develop the movement potential of the hexapod robot comprehensively, kinematics analysis and dynamics analysis are made to be foundation of mathematics. The adaptation of the analysis method is improved and the hexapod robot single-leg workspace equation is got with combining vector method and geometric method. Based on the relative motion theory, a method...
For investigating moisture content variation law of thin layer carrots during hot-air drying, In this paper, the dynamic modeling and drying characteristics were studied, two models were used in the experimental data, the effects of air temperature, air-flow rate and sample thickness on drying kinetics of carrot slices were investigated, and the moisture effective diffusion coefficients were calculated...
Antioxidant-rich fractions were extracted from sea buckthorn (Hippophae rhamnoides) seeds using various solvents, including acetone, methanol, ethanol, ethyl acetate, water and mixtures of different solvents, and analyzed for their phenolic components. The antioxidant activity of the extracts was evaluated using a copper-catalyzed lecithin liposome oxidation assay. At 250 µg/mL concentration, the...
The mechanism of honeysuckle quality degeneration in hot air drying was studied by measuring honeysuckle appearance color, relative conductivity, the content of chlorophyll, total phenol and chlorogenic acid. Results showed that enzymatic browning was determined as the major factor in the quality degeneration of hot air dried honeysuckle. Chlorogenic acid as the main substrate of the enzymatic browning...
Ultrasound can enhance mass transfer rate inside and outside materials during dehydration, so it's often used to strengthen osmotic dehydration. Yet osmotic dehydration can't obtain dry products and is usually applied as pretreatment for other drying process. Ultrasonic osmotic dehydration combined hot-air drying process is investigated in this paper. The influences of operation parameters such as...
