Development of Red Pepper Washer Using Ultrasonics and Brush

Abstract

It is essential to wash the foreign matters on the surface of red peppers. Therefore, this study was carried out to develop the red pepper washer using ultrasoincs and rotary brushs. To reduce the damage of red peppers and to increase the washing rate of them, the horizontal brush types of red pepper washer were tested and analyzed. As a results, it was clear that the washing water temperature and the rate of adsorption didn't affect the weight and quality of red pepper. Ultrasonics, newly devised rotary and fixed brush combination increased the washing rate and discharge capacity remarkably.
