Test and Study on Small-scale Precooling Equipment Used in Fruit and Vegetable Producing Area
摘要
Abstract
The necessity of developing small-scale precoohng equipment for monomer farmers was analyzed, the technical requirements of pre-cooling equipment were pointed out. On the basis of this, a new kind of small-scale precooling equipment in which cooling package is separated from refrigeration machine was proposed, single-layer and multi-layer experiments were done in an insulation package using stainless steel balls filled with water as study material. The results showed that, in single-layer experiment, the temperature variation law of stainless steel balls could be fitted with an equation of y = 22.57e-0.0023x, determination coefficient R2 = 0.984 7, 1/2, 3/4, 7/8 precooling time 39, 70 and 104 min respectively. In multi-layer experiment, the temperature of up layer balls decreased fast, while bottom balls decreased slowest. The temperature decreasing situation of topside balls was similar with that of single-layer balls, approaching to index variation law, the fitted curve equation was y = -0. 1098x + 25. 619, R2 = 0.9667; temperature increased from topside layer to lowest layer, so the bottom layer fruit and vegetable temperature should be viewed as the index whether up to setting value; 1/2, 3/4, 7/8 precooling time were 55, 91 and 130 min. The study will provide reference for development of precooling equipment in producing area.关键词
