The equipment process of the fruit drying production line mainly includes raw material processing, pretreatment, drying, and packaging. Each step requires corresponding equipment to ensure product quality and production efficiency. Below is a detailed description of the process flow and equipment:

‌1. Raw Material Processing‌
‌Cleaning and Sorting‌: After entering the production line, raw materials are first cleaned using a roller washing machine, which removes surface dirt and impurities with high-pressure water flow and brushes. For soft fruits (e.g., bayberries, strawberries), the water pressure is recommended to be controlled at 0.3-0.5MPa to prevent fruit damage; for hard fruits (e.g., kiwis, apples), it can be increased to 0.8MPa‌1.
‌Sorting Equipment‌: Equipped with an optical sorter, which uses CCD cameras to identify color and shape, removing moldy or insect-infested fruits. Color difference parameters should be set according to fruit characteristics, e.g., the color difference range for mango ripeness determination should be set at ΔE≤5‌1.
‌2. Pretreatment‌
‌Slicing/Cutting‌: Suitable slicers are selected based on fruit characteristics. For example, serrated blades are recommended for pineapples, with a thickness of 5-8mm to ensure uniform drying‌1.
‌Peeling and Pitting‌: Halving machines or pitting knives are used to remove pits, and peeling agents or hot alkali solutions (e.g., 1.0-2.5% sodium hydroxide solution) are used for peeling, followed by rinsing with clean water.
‌Color Protection‌: The processed fruit slices are immersed in a 1-3% salt solution to prevent oxidation and discoloration.
‌3. Drying‌
‌Drying Equipment‌: Air energy dryers or hot air drying equipment are used, with temperature, humidity, and time controlled via PLC touch screens. Initial low-temperature heating and dehumidification (humidity 60%, temperature 42℃) are followed by gradual heating (humidity 30%, temperature 50℃), and finally color fixation and humidity control (humidity 15%).
‌Drying Process‌: The processed materials are sent to the drying room, with the initial temperature set at 55℃ and the final temperature at 65℃. The end relative humidity is controlled at 20-30%, and the drying time is adjusted based on material thickness and characteristics.
‌4. Packaging‌
‌Grading and Packaging‌: The dried fruits are graded by size and color using grading equipment, then sealed using packaging machines to ensure product hygiene and shelf life.
‌Metal Detection and Coding‌: After packaging, metal detection equipment is used to detect foreign objects, and coding machines are used to mark production dates and batch information.
‌5. Other Functions‌
‌Multifunctionality‌: The fruit drying production line can also be used to produce fruit and vegetable chips and crispy slices, with flexible equipment configurations that can be adjusted according to customer needs.
‌Automation and Hygiene‌: The production line adopts a modular design with a high degree of automation. All parts in contact with materials are made of 304 stainless steel, meeting food hygiene standards.

Features

• The equipment is divided into three sections, each of which controls the temperature and speed of the material.
• When the material enters another section of equipment, it will be turned over to ensure the uniformity of material drying.
• The inside of the drying chamber is heated by steam to ensure that the moisture of the material is fully evaporated while avoiding the phenomenon of being baked and smashed.
• The steam used in the equipment will be fully utilized and recycled during the production process to ensure unnecessary energy loss.
