GMP Food Workshop Compliance Guide: The Core of Cleanroom & Purification Engineering

Many food companies, when pursuing compliance, tend to focus only on raw materials and production processes, while overlooking the critical role of the cleanroom. Uncontrolled temperature and humidity, along with substandard cleanliness, directly lead to product mold and excessive bacterial counts. This not only affects production capacity but also poses potential compliance risks.

Purification Engineering ≠ Ordinary Decoration – Fit is Key

A professional purification project must follow GMP standards and food hygiene regulations, adhering to “no dead corners, easy cleaning, controllable” principles. The right selection of core equipment is critical.

Three Core Equipment Systems Working Together

1. Clean Air Handling Unit – The Environmental Control Hub
   Three-stage filtration (pre-filter, medium, HEPA) captures 99.99% of particles ≥0.3µm. Temperature/humidity control within ±1℃/±5% RH. For example: low-temperature meat products require 10-15℃, ≤60% RH; bakeries need 25-30℃, 40-50% RH.
2. Air Shower + Steel Door – Dual Access Protection
   Air shower uses 25m/s high-speed airflow to remove dust and hair from clothing. Steel door (304 stainless steel, double silicone seals) maintains ≥5Pa pressure differential, is impact-resistant, easy to clean, and corrosion-resistant – effectively isolating clean from non-clean areas.
3. Ozone Sterilization – Tackling Hidden Microbial Contamination
   Broad-spectrum, residue-free, no dead corners. Ozone kills bacteria and mold on surfaces and in the air, then decomposes into oxygen – no secondary pollution. Works with the air handling unit and air shower for full-area disinfection.

Professionalism Throughout – Synergy for Long-Term Success

Every step – from site survey and zoning to installation, commissioning, and maintenance – must strictly follow GMP standards. Floors and walls use seamless, easy-to-clean materials; corners are rounded to eliminate dust traps. Cleanliness levels from Class 100,000 to Class 100 are customized based on production scale and product type.

Cleanliness is the foundation; compliance leads to sustainability. Investing in professional purification engineering is not a burden, but a solid guarantee for competitiveness, risk reduction, and long-term growth.
