# Industrial Specification: Drying/Evaporation Tunnel

## 1. Technical Definition
A heated chamber within a bottle sterilizer that removes residual moisture or evaporates sterilizing agents from bottle surfaces after rinsing.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **80-120°C with 0.5-2.0 m/s air velocity**. Failure boundary: **Material yield strength exceeded at 150°C with 0.1 MPa thermal stress or moisture content &gt;0.5% by weight**, Mechanism: **Thermal expansion mismatch between 304 stainless steel (17.3 μm/m·K) and heating elements (13.0 μm/m·K) causing stress concentration at welds**.

### 2.1 Analytical Physics Model
Governed by the **LMTD Logarithmic Mean Temperature Difference**:

> **Primary Equation**: $Q = U \cdot A \cdot \Delta T_{lm}$  
> **Engineering Impact**: Sizing validation for pasteurization and cooling tunnels.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| U | Heat Transfer Coeff | Engineering Constant |
| A | Area | Engineering Constant |
| \Delta T_{lm} | LMTD | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| PID controller integral windup causing 180°C overshoot | 8 | Polymer bottle deformation exceeding 2% dimensional change | Cascade control with secondary RTD sensors and anti-windup algorithm (Kp=2.5, Ti=120s, Td=30s) |
| Laminar airflow disruption from 15° angular misalignment of inlet vanes | 8 | Moisture gradient &gt;10% across tunnel cross-section | Laser-aligned vane installation with 0.5° tolerance and computational fluid dynamics validation |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What is the primary function of a drying/evaporation tunnel in beverage manufacturing?
**A**: The drying/evaporation tunnel removes residual moisture and evaporates sterilizing agents from bottle surfaces after the rinsing process, ensuring bottles are completely dry and ready for filling.

### Q: Why is stainless steel (AISI 304/316) used for this equipment?
**A**: Stainless steel AISI 304/316 provides excellent corrosion resistance, hygiene, and durability required in beverage manufacturing environments where equipment is exposed to moisture, heat, and cleaning chemicals.

### Q: How does the temperature control system work in the drying tunnel?
**A**: Temperature sensors monitor the tunnel environment, while controllers adjust heating elements to maintain optimal drying temperatures. Air circulation fans ensure even heat distribution for consistent evaporation.
