摘要

这项工作的目的是通过萨卡特卡斯州首府地区的太阳辐射特征,减少番石榴(Psidium guajava)切片的水分含量。采用自然对流和强制对流两种方法来实现本研究的目的。所选番石榴来自萨卡特卡斯的哈尔帕市。用OHAUS MB45热重量表评估水分,然后将番石榴片放置在长34.2 cm、宽24 cm的聚合物网状托盘中。它们被放入一个透明的干燥器中,该干燥器的底座尺寸为74厘米× 80厘米,正面高度为13厘米,后部高度为40厘米。在干燥机内放置一个Checktemp 1温度计来评估干燥过程中的温度。干燥8 h后,番石榴的初始湿度为50.51%,自然对流和强制对流的最终湿度分别为8.08%和8.32%。

Deshidratación de guayaba (Psidium guajava) en forma de rodaja mediante radiación solar en un secador directo
The objective of this work is to reduce the moisture content of the guava (Psidium guajava) cut in slices, through the solar radiation characteristic in the area of the capital of the state of Zacatecas. Natural convection and forced convection were used to achieve the objective of this study. The selected guava comes from the municipality of Jalpa, Zacatecas. Moisture was evaluated with an OHAUS MB45 thermogravimetric scale, then the guava slices were placed in polymer mesh trays with dimensions of 34.2 cm long and 24 cm wide. They were introduced inside a transparent dryer with dimensions of 74 cm x 80 cm of base and a frontal height of 13 cm and posterior of 40 cm. A Checktemp 1 thermometer was placed inside the dryers to evaluate the temperature in the drying process. The initial humidity of the guava was 50.51%, the final moisture obtained in the natural convection was 8.08%, while in the forced convection it was 8.32%, after 8 hours of drying.
