Litchi dry processing technology
Harvested lychees with yellow stems, bright red skin, fully mature and juicy, are used as the main raw material for this process. Key processing steps: 1. Sweating and Grading: After picking, the lychee fruits should be spread out in baskets for 5 to 10 days. They should be turned regularly to allow some moisture to evaporate, causing the skin to turn from red to a darker shade. Once the fruit is slightly dehydrated, it is sorted by size for further processing. 2. Drying: After grading, the lychees are sun-dried during the day in a well-ventilated area with direct sunlight. At night, they are roasted to ensure even drying. It's important to turn them frequently during the baking process to achieve uniform dehydration. The temperature should remain stable throughout. In the first one or two days, use a low heat setting, keeping the temperature between 35–40°C. From the third to the fourth day, increase the heat to 45–60°C, and on the fifth and sixth days, reduce it to below 50°C. The entire drying process should be consistent, typically taking 7 to 10 days. Alternatively, you can use a far-infrared oven, which usually takes about 4 to 5 days per batch. 3. Quality of Dried Lychees: High-quality dried lychees should maintain their shape, be plump, dry, with a brownish skin that is light and elastic. When shelled, the flesh should be soft and sweet, offering a rich and delicious flavor. This traditional method ensures that the natural sweetness and texture of the lychee are preserved, making the dried product both flavorful and long-lasting. Whether used in desserts, teas, or as a snack, properly dried lychees are a prized delicacy in many cultures.
