Drying green walnuts is a process that can help preserve the flavor and quality of this nutritious food. Here, we will explore 5 effective methods for drying walnuts, ranging from traditional techniques to the use of modern technologies.
Drying Walnuts in the Oven
To dry walnuts in the oven, first remove the green husks and select the healthy walnuts. After washing, allow them to dry completely. Arrange the walnuts in a single layer on a baking tray, ensuring there is space between them. Set the oven temperature to about 40 to 43 degrees Celsius and let the walnuts dry slowly. During the process, turn the walnuts over a few times to ensure even heat distribution. After a few hours, check the kernel of one of the walnuts; if it is completely dry and crunchy, you can package them.

Drying Walnuts in Sunlight and Shade
Drying walnuts in sunlight is another traditional method. Place the walnuts on a tray or mesh and expose them to gentle sunlight. This process usually takes several days. In this method, during the nights and in rainy conditions, move the walnuts to a dry, covered environment. Additionally, to avoid direct sunlight, you can dry the walnuts in the shade; this helps preserve the quality of the walnut kernel.
If you are drying the walnut kernels, place them in a thin layer on a mesh and move them every few hours. The drying time depends on the humidity of the environment and weather conditions.
Using a Dehydrator and Freeze-Drying
To dry walnuts using a dehydrator, place the peeled walnuts on the trays of the device and set the temperature to about 40 to 43 degrees Celsius. This method gradually removes the moisture from the walnuts due to the continuous flow of warm air. Additionally, in the freeze-drying method, the kernels are first frozen and then the moisture is removed under vacuum conditions. This method is more suitable for industrial production and requires precision and special equipment.
Ultimately, by choosing one of these methods and following the necessary tips, you can prepare delicious and high-quality walnuts for use throughout the year.
