Key points for GMP acceptance inspection of food factories
GMP equipment acceptance in food factories focuses on verifying the compliance, hygiene, and stability of various production, purification, disinfection, and testing equipment to eliminate production contamination risks and ensure the entire food production process is standardized and controllable.
Cleanroom equipment is the primary focus of acceptance, mainly including cleanroom air conditioning, FFU fan units, air showers, and material transfer windows. Acceptance emphasizes checking that filters are intact, cleanroom pressure differentials meet standards, equipment interlocks and disinfection functions are normal, and instrument calibration records are complete, ensuring a clean workshop and preventing cross-contamination.
Raw material pretreatment equipment includes washing, crushing, mixing, homogenizing, and conveying equipment. All food contact surfaces must be made of 304 or 316L food-grade stainless steel, with no dead corners, easy disassembly and cleaning, and strictly prohibiting material accumulation and oil leakage. Food-grade lubricating oil must be used to prevent material contamination.
Heat processing and sterilization equipment is a critical control point, encompassing autoclaves, UHT/pasteurizers, jacketed kettles, and baking equipment. The acceptance inspection focuses on ensuring the temperature control and pressure recording devices are intact, instruments are within their calibration validity period, and heat distribution and sterilization parameter records are complete, guaranteeing the sterilization process is compliant and effective.
Filling, dispensing, and packaging equipment directly affects the quality of the finished product. Equipment piping must be free of blind pipes and cleaning dead zones, and support CIP online cleaning. Accurate filling and metering with no drips are required, as well as tight sealing equipment to ensure a clean and traceable packaging process.
The cleaning and disinfection system primarily consists of CIP automatic cleaning stations, disinfection tanks, ozone, and ultraviolet disinfection equipment. Acceptance verification includes ensuring full coverage of cleaning sprays without blind spots, monitorable and recordable cleaning concentrations, normal operation of disinfection equipment, and separate use of tools to avoid cross-contamination.
Cold storage, quick-freezing equipment, constant-temperature fermentation equipment, and raw material storage tanks, among other temperature-controlled storage equipment, must have 24-hour continuous temperature recording capabilities, and temperature probes must be calibrated regularly. Equipment must be well-insulated and sealed, with no risk of condensation contamination, and storage tanks must have no dead zones for material accumulation, ensuring the safe and stable storage of raw materials and semi-finished products.
Laboratory testing equipment, including laminar flow hoods, autoclaves, incubators, precision balances, and ATP analyzers, is crucial for quality control. Acceptance requires that all metrology and testing instruments possess valid calibration certificates, be in good working order, and meet daily quality and microbiological testing needs.
Public utilities are also included in the acceptance scope, primarily including pure water equipment, oil-free compressed air systems, and protective facilities such as fly control, rodent control, and explosion-proof lighting, comprehensively ensuring clean and safe production conditions in the workshop.
In summary, GMP equipment acceptance uniformly requires: compliant equipment materials, easy-to-clean structure, reasonable layout, separation of raw and cooked food processing areas, and complete equipment maintenance, cleaning and disinfection, and validation records to ensure the safe, compliant, and stable operation of the entire production system.
