Experimental Study in of Pressure Pre-cooling of Grape

Abstract

Abstract: According to the principle of pressure pre-cooling,an experimental device has been set up.The experimental cooling velocity has been conducted in five different test conditions of different air vent holes and five different test conditions of different air pressures.The curve of temperature decrease has been drawn during 2.5 hours.The results of this test proved that the reasonable choice of pressure and air vent hole was the critical element for cooing velocity and cooling uniformity.

Key words: , Grape Pressure pre-cooling Pressure Size of vent hole；
