In the formula, G is the mass of dry material in a batch of operations, kg, S is dry area, M2.
In this experiment, the self-made microwave temperature-controlled drying equipment was used to dry the treated peanuts with the lowest power (120 W) until no loss of water.
microwave drying equipment
1.5 method of perception evaluation
The quality of drying is evaluated mainly from the color of peanut kernels.
1 test results and analysis
1.1 conventional microwave test results and analysis
The higher the microwave power, the steeper the drying curve, the shorter the drying time, the higher the microwave power and the higher the temperature. At the beginning of drying, the temperature rises rapidly, and when the temperature reaches the highest point, the moisture content has not reached the requirement. The microwave oven continues to work. After the temperature rises inertia, it returns to a relatively stable range.
1.2 temperature control microwave test results and analysis In order to reflect the influence of drying power and temperature range on drying rate, the minimum drying power and the maximum drying power were selected as 1.20 W/g and 3.52 W/g, and the temperature range was 50-55 C and 35-40 C. The drying characteristics of peanut under microwave drying were observed.
