Introduction

Fruit transport within a sorting line plays a critical role in maintaining product quality. Soft fruits such as blueberries and apples are particularly sensitive to mechanical damage.

The choice of transport method directly affects:

• product quality
• shelf life
• waste levels

---

Problem: Mechanical Damage

Mechanical handling often causes:

• bruising
• micro-damage
• invisible structural defects

– which may only appear during storage

---

Mechanical Transport – Limitations

Typical systems (belts, channels) involve:

• contact with hard surfaces
• pressure points
• impacts between elements

Result:
– higher product losses
– reduced quality

---

How Water Transport Works

Water transport is based on:

• water flow
• buoyancy
• absence of direct pressure

– fruit moves smoothly and naturally

---

Advantages of Water Transport

1. Minimal mechanical stress
No pressure points reduces bruising

2. Gentle handling
No contact with hard surfaces

3. Stable product flow
Consistent and controlled movement

4. Reduced waste
Higher share of premium-quality fruit

---

Impact on Shelf Life

Fewer defects result in:

– longer storage time
– better final product quality
– fewer complaints

---

Comparison: Mechanical vs Water Transport

Parameter	Mechanical	Water
Damage risk	high	very low
Flow consistency	medium	high
Shelf life	shorter	longer
Final quality	variable	stable

---

When to Use Water Transport

Especially recommended for:

• soft fruits
• high quality standards
• high-capacity processing lines

---

Conclusion

Water transport:

• reduces damage
• extends shelf life
• improves overall efficiency

– making it essential for modern fruit sorting lines
