Key Components and Functions of a Freeze-Dried Fruit Packaging Machine

A professional freeze-dried fruit packaging machine typically integrates the following modules to form an automated or semi-automated production line:

1. Feeding and Metering Filling System

Challenge: Freeze-dried fruits are large, lightweight, and fragile.

Solutions:

1) Weighing Filler (Multi-Head Scale): The most accurate and commonly used method. It achieves high-speed, high-precision weighing (accuracy up to ±0.1-0.5 grams) through the combination of multiple weighing hoppers, and is highly adaptable to product shapes.

2) Volumetric Filler: Suitable for products with uniform particle size. Weight is controlled by measuring volume; it is faster, but accuracy is affected by changes in product density.

3) Vibrating Feeder/Conveyor Belt: Gently conveys the product to the filling port, preventing breakage.

2. Vacuum-Filled Nitrogen System (Core)

Workflow:

a. Bag/Can Opening: Position the empty packaging container.

b. Filling: Add precisely measured amounts of freeze-dried fruit.

c. Vacuuming: Forcefully extract the air (containing oxygen and moisture) from the packaging container.

d. Sealing: Perform heat sealing (bags) or screw cap/compression cap (cans) in a nitrogen environment.

3. Sealing System

1) For bagged products: Use heat sealing to ensure a firm, smooth, and leak-free seal. A cooling device may be required to quickly set the seal.

2) For canned products: Use an automatic capping, screw capping, or compression capping device to ensure a tight seal.

4. Control System and Monitoring

1) PLC Control: Precisely control parameters such as time, vacuum level, nitrogen filling volume, and temperature at each step.

2) Residual Oxygen Detector (Optional but Important): Online or sampling detection of oxygen content within the finished product packaging is a direct indicator of packaging effectiveness and shelf-life assurance. High-quality freeze-dried packaging typically requires residual oxygen levels below 2%-3%, or even lower.

5. Auxiliary and Downstream Equipment

1) Vibration Leveler (Canning): Gently vibrates the can after filling to ensure a tighter product arrangement, reducing top space, saving nitrogen, and improving packaging stability.

2) Labeling Machine/Installation Machine: Prints production date, batch number, and other information.

3) Cartoning/Packaging Machine: Completes secondary packaging.
