# Industrial Specification: Agitation Mechanism

## 1. Technical Definition
A mechanical system designed to mix and homogenize yogurt culture and milk within a fermentation tank.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 m/s tip speed, 10-100 rpm rotational speed, 0.1-0.5 kW power input**. Failure boundary: **Shear stress exceeding 150 Pa at impeller tip, bearing temperature exceeding 80°C, shaft deflection exceeding 0.5 mm/m length**, Mechanism: **Fatigue failure from cyclic loading at 0.5-3 Hz operational frequency, bearing seizure due to lubricant breakdown at 80°C, shaft bending from unbalanced mass exceeding 0.1 kg at 0.5 m radius**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$  
> **Engineering Impact**: Calculates centrifugal force for vibratory sifters/feeders.

- **Caution**: 

### Q: Why is Stainless Steel 316L used for this agitation mechanism?
**A**: Stainless Steel 316L offers superior corrosion resistance against acidic dairy products like yogurt, meets food safety standards, and ensures durability in sanitary food manufacturing environments.

### Q: How does this agitation mechanism improve yogurt production?
**A**: It ensures thorough mixing and homogenization of milk and yogurt culture, promoting consistent fermentation, preventing stratification, and enhancing product quality and texture throughout the tank.

### Q: What maintenance does the seal assembly require?
**A**: The seal assembly should be inspected regularly for wear and cleaned to prevent contamination. Follow manufacturer guidelines for lubrication and replacement to maintain hygiene and prevent leaks in the fermentation tank.

## 6. Manufacturing Compliance
