Comprehensive Guide to Fruit Sorting and Washing Machines
Fruit sorting and washing machines are essential equipment in the food processing industry, specifically in facilities that handle fruit and vegetable sorting, grading, and washing. These machines not only streamline the processing but also enhance the hygiene and quality of the produce. Here, we’ll break down the different types of fruit sorting machines, washing equipment, and the technical features they offer, which vary depending on processing needs, from small-scale operations to industrial settings.
1. Plastic Crate Washing Machine
Plastic crate washing machines are designed for cleaning crates, trays, and baskets used for storing and transporting fruits, vegetables, seafood, and other food products. These machines are commonly found in central kitchens, fast-food chains, and logistics centers where cleanliness and sanitation are crucial.
Washing Modes
The washing machine includes four washing modes to ensure efficient cleaning:
- Pre-washing: Soaks crates, softening dirt and attachments.
- Main washing: Utilizes high-pressure water to clean.
- Rinsing: Reuses clean water from previous stages.
- Final washing: Employs fresh water for a thorough wash.

| Material | Constructed from 304 stainless steel for durability and rust resistance |
| Water Recycling | Circulates water from previous modes to reduce water usage |
| High-Pressure Pump | Allows full cleaning without chemicals |
| Power-Off Protection | Prevents dry heating if water levels are low |
| Temperature Control | Each water tank has independent temperature control for efficiency |
| Nozzle Rotation | Offers 360° cleaning coverage |
| Disassembly for Cleaning | Connection parts can be removed for easy maintenance |
2. Fruit Sorting Machines
Fruit sorting machines are used to grade fruits by size, weight, or shape, improving quality by separating damaged or undersized produce. Two main types include rolling rail and weight grading fruit sorting machines.
Types of Fruit Sorting Machines
| Sorting Machine Type | Description | Capacity |
|---|---|---|
| Rolling Rail Sorting Machine | Uses spiral tracks with rollers for size-based sorting, suitable for apples, onions, and strawberries. | 1-20 tons/hour |
| Weight Grading Machine | Measures the weight of produce using load cells for precise categorization by weight. | 120 pcs/min |
| Diameter-Based Sorting Machine | Gradually increases belt spacing to sort by fruit diameter. Suitable for delicate produce like kiwi and litchi. | 0.5-3 tons/hour |
Rolling Rail Fruit Sorting Machine
The rolling rail sorting machine uses rotating spiral tracks and rollers for accurate sorting based on fruit size. Fruits tumble freely on rollers, ensuring they are evenly exposed for better sorting accuracy.
