Another critical principle at play in these machines is the separation process. Simultaneously with mechanical pressing, an internal sieve within the equipment acts as a filter. As the fruit and vegetable waste undergoes compression, the moisture is forced to pass through the sieve, while the solid components are retained. This efficient separation ensures that water and solids are effectively isolated. The separated water exits the machine through a drainage outlet, while the solid waste continues to be pressed until most of the moisture is removed.

Operating Process

The operational process of fruit and vegetable waste dewatering machines generally encompasses the following steps:

1. Feeding: Introduce the fruit and vegetable waste into the screw press machine, initiating the dewatering process.

2. Mechanical Pressing: The internal screw shaft starts to rotate, applying pressure to the waste, expelling moisture from the solid portion.

3. Separation: Simultaneously, water is forced through the sieve, and the solid waste is obstructed by it.

4. Drainage: The separated water is directed out of the machine through a drainage outlet for further treatment or recycling.

5. Solid Waste Collection: After dewatering, the solid waste retains a significantly reduced moisture content, making it easier to manage through incineration, composting, or other disposal methods.

Advantages and Applications

Screw press machines for fruit and vegetable waste dewatering offer several advantages:

1. Volume Reduction: Dewatered solid waste occupies less space, facilitating its subsequent handling and transportation.
