| 中文摘要: |
| 为了提高单缸立式软冰淇淋机生产的冰淇淋的膨化率，课题组对其浮动刮刀片的刮削机理进行了理论研究及力学分析，并
对螺旋搅拌结构原理进行了探究，确定了搅拌器工作时的最小转速。通过试验得出在冷冻过程中影响冰淇淋质量的主要因素为缸筒内冰淇淋浆液的加入量、粉料
与水的配比以及设定的电流极值，并进行了正交试验。实验结果表明：冰淇淋机搅拌器的最小转速为155.6 r/min；当加入的浆液量0.9 L，粉料与水的配比（质量比
）为1[DK]∶3.0，电流极值设定4.5 A时可得最高的膨化率82.0%；缸筒内浆液量的多少是影响膨化率的最关键因素，浆液宜采用齿轮泵间歇式引入冷冻缸内的方式
来提高膨化率。 |
| 英文摘要: |
| In order to improve the expansion rate of ice cream produced by a single cylinder vertical soft ice cream machine，the oretical research and
mechanical analysis of the scraping mechanism of the floating scraper were carried out. The principle of the spiral agitating structure was investigated，and the minimum rotational speed of
the agitator was determined. Through experiments，the main factors affecting the quality of ice cream in the freezing process were the amount of ice cream slurry in the cylinder，the ratio
of powder to water and the set current limit，and the orthogonal test was carried out. The experiment result shows that the minimum speed of the ice cream mixer is 155.6 r/min. When the
amount of slurry added is 0.9 L，the ratio of powder to water is 1:3.0 (mass ratio)，and the current value is set at 4.5 A，the highest puffing was obtained. The rate is 82.0%. The amount
of slurry in the cylinder is the most important factor affecting the expansion rate. The slurry should be introduced into the freezing cylinder intermittently by gear pump to increase the
expansion rate. |
