The traditional vanilla curing process can take up to three months. Although vanilla pods can be dried in an oven, faster drying methods can result in inferior quality and high costs. The objective of this paper was to evaluate the participatory development of a vanilla pod dryer, adapted to local conditions and based on the four principles of sustainability, to improve vanilla producers' traditional vanilla bean drying process. In participatory workshops attended by 11 participants and four facilitators, the traditional vanilla curing process was analyzed, and the basic constructional and functional parameters for a vanilla pod dryer were defined. Two models of solar dryers were constructed and tested in cooperation with the vanilla producers over a period of four months. The direct model performed better than either the indirect model or traditional sun drying. The vanilla dried significantly faster in the direct solar dryer. The drying rate in the solar dryer model was significantly higher than the drying rate of sun drying. No statistically significant difference was found in the content of vanillin for treated and untreated pods. However, the vanillin content of solar-dried vanilla is slightly higher than that of sun-dried vanilla, meaning that use of the solar dryer model did not affect vanillin content and therefore quality. In the endogenous development focus, participatory learning processes are fundamental to promoting intervention strategies, optimizing resources, and empowering local actors.

传统的香草腌制过程可能需要长达三个月的时间。虽然香草荚可以在烤箱中干燥，但更快的干燥方法可能会导致质量低劣和成本高昂。本文的目的是评估香草荚干燥机的参与式开发，该干燥机适合当地条件并基于可持续性的四个原则，以改进香草生产商的传统香草豆干燥工艺。在由 11 名参与者和 4 名主持人参加的参与式研讨会上，分析了传统的香草腌制过程，并定义了香草荚干燥机的基本结构和功能参数。与香草生产商合作，在四个月的时间内建造并测试了两种型号的太阳能干燥机。直接模型比间接模型或传统晒干的表现更好。香草在直接太阳能干燥机中干燥得更快。太阳能干燥机模型的干燥速率明显高于阳光干燥的干燥速率。处理过的豆荚和未处理过的豆荚中香草醛的含量没有发现统计学上的显着差异。然而，晒干香草的香草醛含量略高于晒干香草，这意味着使用太阳能干燥机模型不会影响香草醛含量，从而影响质量。在内生发展重点中，参与式学习过程对于促进干预策略、优化资源和增强当地参与者的能力至关重要。
