# Industrial Specification: Rotary Fruit and Vegetable Blanching Drum

## 1. Technical Definition
Rotating drum component for uniform thermal processing of fruits and vegetables.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.2-1.5 MPa steam pressure, 70-100°C water temperature, 2-15 rpm rotation speed**. Failure boundary: **Drum shell stress exceeds 250 MPa yield strength of 304 stainless steel, bearing temperature exceeds 120°C lubricant breakdown point, or rotational imbalance exceeds 0.5 mm vibration amplitude**, Mechanism: **Thermal fatigue from cyclic heating/cooling (ΔT=30-80°C) causing stress concentration at weld joints, cavitation erosion from steam bubble collapse at 0.8 MPa pressure differential, or torsional resonance at 8-12 Hz matching drum natural frequency**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.

- **Caution**: 

### Q: What are the main advantages of using a rotary blanching drum for fruits and vegetables?
**A**: The rotary blanching drum ensures uniform thermal processing through continuous rotation, preventing uneven cooking and maintaining consistent texture and color. Its internal baffles promote even heat distribution, while food-grade materials prevent contamination.

### Q: How does the stainless steel 316L construction benefit food processing applications?
**A**: Stainless Steel 316L offers superior corrosion resistance against acidic fruits and vegetables, meets food safety standards, is easy to clean and sanitize, and maintains structural integrity at high operating temperatures.

### Q: What maintenance is required for the rotary blanching drum components?
**A**: Regular inspection of drive shaft alignment, cleaning of drum shell and baffles after each use, lubrication of support rollers, and checking material thickness for wear. The food-grade polypropylene components should be inspected for cracks or degradation.
