# Industrial Specification: Temperature-Controlled Shelves

## 1. Technical Definition
Temperature-regulated shelving system within drying chambers for precise material handling during dehydration processes.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **40-80°C**. Failure boundary: **Below 35°C causes condensation formation; above 85°C initiates polymer shelf degradation**, Mechanism: **Thermal expansion mismatch between aluminum shelf frame (α=23.1×10⁻⁶/K) and polycarbonate load surface (α=70×10⁻⁶/K) creates stress concentrations exceeding yield strength at ΔT&gt;45K**.

### 2.1 Analytical Physics Model
Governed by the **Heat Sterilization F0 Lethality Model**:

> **Primary Equation**: $F_0 = \int_{0}^{t} 10^{(T-121.1)/z} dt$  
> **Engineering Impact**: Validates microbial reduction integrity for aseptic packaging.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| T | Process Temp (°C) | **$T \in [40-80°C]$ °C** (Per `temperature_range`) |
| t | Exposure Time (min) | Engineering Constant |
| z | Z-value | **10 °C** (Standard for *C. botulinum*) |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
