Design and Experiment of Ultrasonic Cleaning for Crops

Abstract

This paper aims to design an ultrasonic cleaning machine for crops to provide the engineers with very useful information. First, the new practical model is designed, including the body shell, cleaning tank, ultrasonic generator and control system. Second, three vegetables (lettuce, cabbage and potato) are used in the experiment. The result shows the damage percentage after washed was 0%. The root vegetables are cleaned faster in this machine.

Use of Ultrasonic Cleaning Technology in the Whole Process of Fruit and Vegetable Processing

“…Ultrasonic pressure causes the bubble to contract, thereby increasing the temperature, on the assumption that the hydrostatic pressure P 1 in the air is equivalent to that in the bubble and is compressed by the adiabatic process [ 34 ]. Before the bubbles contract, the pressure was P 0 and the water temperature was T 1 .…”
