应用于冰浆湿冷差压预冷系统的包装箱开孔结构实验研究
Experimental Study on Opening Structure of the Packaging Box Applied to Ice Slurry Wet Cooling Differential Pressure Precooling System
摘要
Abstract
Aiming at the problems of low humidity and high dry consumption in the present differential pressure precooling room,the combination of the ice slurry wet cooling system with the differential pressure precooling is proposed,and a novel differential pressure ice slurry wet precooling test platform is designed and built in this paper.Taking tomatoes as precooling objects,the effects of opening structure of packaging box on the system and tomatoes are studied.The results showed that the number of openings has little effect on the precooling time and the precooling rate of tomato,while the increase of opening ratios shorten the precooling time and increase the precooling rate.The more the number of openings and the greater the opening ratio,the smaller the peak value of the temperature variation coefficient during the precooling process,that is,the better the precooling uniformity.When the number of openings is 9(the opening rate of 20%)and the opening rate is 25%(the number of openings of 4),the peak values of temperature variation coefficient are 0.004 6 and 0.003 6,respectively.The weight loss ratio of tomatoes increases with the increase of the number of openings and decrease with the increase of the opening ratios.The overall weight loss ratio is about 0.1%,which is much lower than that of tomatoes in the traditional differential pressure precooling system.关键词
