# Industrial Specification: Sieve Basket

## 1. Technical Definition
The rotating cylindrical component in a centrifugal sieving machine that separates starch particles by size through centrifugal force.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **300-1200 rpm rotational speed, 0.5-3.0 mm aperture diameter, 50-200 kg/h starch throughput**. Failure boundary: **Material yield strength exceeded at 1500 rpm (316L stainless steel: 290 MPa yield), aperture deformation beyond 10% dimensional tolerance**, Mechanism: **Centrifugal stress exceeding material yield strength (σ_c = ρω²r²/2), where ρ=8000 kg/m³, ω=angular velocity, r=0.25 m radius; fatigue from cyclic loading at 10⁷ cycles (S-N curve for 316L)**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Starch slurry pH &lt;4.5 causing chloride stress corrosion cracking | 8 | Radial crack propagation from basket periphery, leading to catastrophic structural failure at 1200 rpm | Material upgrade to duplex stainless steel (2205) with 0.2% chloride tolerance limit, implement real-time pH monitoring with automatic shutdown at pH 4.8 |
| Unbalanced mass loading exceeding 0.5 kg·m at 1000 rpm | 8 | Resonant vibration at 16.67 Hz (1× rotational frequency) exceeding 5 mm/s vibration velocity, causing bearing seizure | Dynamic balancing to ISO 1940 G2.5 standard (2.5 mm/s residual vibration), install vibration sensors with trip point at 4.5 mm/s |

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

### Q: What materials are recommended for food-grade sieve baskets?
**A**: Food-grade sieve baskets typically use stainless steel grades 304 or 316 for corrosion resistance and hygiene, or high-strength alloy steel for demanding applications requiring extra durability.

### Q: How does a centrifugal sieve basket separate starch particles?
**A**: The rotating cylindrical basket uses centrifugal force to push starch slurry against a perforated screen, allowing smaller particles to pass through while retaining larger ones, enabling precise size separation.

### Q: What maintenance is required for sieve baskets in food processing?
**A**: Regular inspection of the perforated screen for wear or clogging, cleaning to prevent contamination, and checking mounting components like flanges and support frames for secure operation are essential maintenance steps.
