Introduction
Analysis of the core content of the standard
| Technical dimensions | GB/T 38458-2020 requirements | Typical parameters of the industry |
|---|---|---|
| Production capacity | ≥rated value, efficiency≥95% | 2000-6000 barrels/hour |
| Filling accuracy | ≤±1% | ±0.5%-1.2% |
| Qualified rate of finished products | ＞99.7% | 98.5-99.9% |
Key technical requirements
The standard puts forward three core requirements for full-automatic flushing, filling and capping machines:
- Flushing system: 100% inner surface coverage and flushing must be achieved, and the residual water quality must meet drinking water standards
- Filling seal: opening torque fluctuation ≤±0.4N·m, leakage rate 0%
- Material safety: surface roughness of finished product water contact area Ra≤0.8μm, bearings require food-grade seals
Safety control system
A certain brand of equipment meets the standard requirements through the following designs:
- Adopt PLC safety circuit (PLc level) and IP65 protective electrical components
- Set up triple interlock protection (stop filling due to lack of barrel, alarm due to lack of cover, shutdown due to abnormal pressure)
- Install 25mm limit devices on key moving parts
Implementation suggestions
When introducing equipment, enterprises should focus on:
- Verify the dead angle rate of the CIP cleaning system
- Test the adaptability of different barrel types (4.5L-20L)
- Establish a regular calibration system (monthly filling accuracy inspection)
