菠萝皮干燥工艺研究

A Study on the Drying Technology of Pineapple Peel

本实验采用了不同的干燥温度和物料厚度对菠萝皮进行干燥,对其干燥曲线进行分析,得出物料厚度对干燥效率影响较大,而干燥温度对菠萝皮的干燥速率呈正相关性。不同干燥温度得到的成品的营养成分是有差别的。通过实验得到,菠萝皮采用厚度为6kg/m2,干燥温度为70℃所得到的产品,均匀松散,颜色均匀,且带有浓郁的菠萝香味。

The drying technologies of pineapple peel were investigated by varying the drying temperature and material thickness, The analysis of the drying curve showed that the material thickness had higher effect on the drying efficiency than the other examined factor and a positive relevance was found between the drying temperature and drying rate. It was also found that the nutrition component of the dried pineapple peel was influenced by the drying temperature. The optimum material thickness and drying temperature were determined as 6 kg/m^2 and 70℃, respectively, under which the product was rich in pineapple aroma, loose-textured and with a uniform color.
