In this study, the storability of maize that dried using a newly designed solar bubble dryer (SBD), solar cabinet dryers (mixed and indirect), and open sun drying at two sample loads—thick layer (21.74 kg/m2) and thin layer (10.87 kg/m2) were evaluated. The dried maize grains were stored in four different farmer houses for 6 months. Storage loss of the grain was recorded over 6 months, at an interval of 2 months. The chemical compositions and germination capacity of dried maize were assessed after drying. The results revealed that significantly lower mean values of total live insect counts, percentage weight loss, percentage of insect‐damaged kernels, and percentage loss of bulk density were recorded in thin layer dried maize across all storage periods. Drying methods posed significant effect on the total live insect count up to 4 months of storage, the lowest number was observed for open sun and solar bubble‐dried grain. Percentage germination was significantly affected by the amount of sample load. The present study showed that drying can slow down insect population development and associated losses during storage. Therefore, SBD can be promoted as part of integrated postharvest handling technique to reduce postharvest loss of maize.

谷物干燥方法对玉米收获后害虫侵袭及理化特性的影响

在这项研究中,使用新设计的太阳能气泡干燥器(SBD),太阳能柜式干燥器(混合式和间接式)以及在两个样品负荷下(厚层(21.74 kg / m 2)和薄层)的开放式阳光干燥干燥的玉米,具有保存性。层(10.87 kg / m 2)进行了评估。干燥的玉米籽粒在四个不同的农舍中存放了6个月。在6个月内,每2个月记录一次谷物的储藏损失。干燥后评估干燥玉米的化学组成和发芽能力。结果表明,在所有存储期间,薄层干燥玉米的活昆虫总计数,重量损失百分率,虫害百分率百分数和体积密度损失百分率均显着降低。干燥方法对最多存储4个月的活昆虫总数有显着影响,在开阔的阳光下和太阳经气泡干燥的谷物中观察到的数量最少。发芽百分比受样品上样量的显着影响。本研究表明,干燥可以减缓昆虫种群的发展以及在储存过程中的相关损失。因此,SBD可以作为收获后综合处理技术的一部分进行推广,以减少玉米收获后的损失。
