Litchi dry processing technology
Freshly harvested lychees with yellow stems, bright red skin, and fully mature flesh are used as the raw material for this process. These lychees are carefully selected to ensure quality and flavor before proceeding to the next steps. Key processing steps include: 1. Sweating and Grading: After being freshly picked, lychees should be spread out in baskets for 5 to 10 days. They need to be turned regularly during this time to allow moisture to evaporate. As the fruit dries, the skin will gradually turn from red to a darker shade of black-red, and the fruit will become more compact. Once this stage is complete, the lychees are sorted by size to ensure uniformity in the final product. 2. Drying Process: After grading, the lychees are dried either in the sun during the day or in a dehydrator at night. It's important to frequently turn the fruit to ensure even drying. The temperature during the initial stages of drying should be kept low—around 35 to 40°C for the first two days. As the process continues, the temperature can be gradually increased to 45 to 60°C for the next two days, and then reduced to below 50°C for the last two days. The entire drying process typically takes 7 to 10 days. Alternatively, a far-infrared oven can be used, with each batch taking about 4 to 5 days to dry completely. 3. Quality Characteristics of Dried Lychees: The final product should have an upright shape, large size, dry texture, and a brownish skin that is light and slightly elastic. When the shell is removed, the flesh should remain soft and naturally sweet, maintaining the original flavor of the fresh fruit. This traditional method ensures that the lychees retain their rich taste and nutritional value, making them a popular choice for both local consumption and export.
