GB/T 41376-2022 in English

Core technical requirements for beer machinery design and manufacturing

Key material standard system

Precision machining process indicators

The material contact surface shall have a maximum roughness of Ra0.8μm, such as the plug valve seat must be ground. The brewing tank stirring shaft shall preferably use the electrochemical polishing process, and the grinding height of the tank inner wall weld shall not exceed 2% of the parent material.

Key points of safety protection design

Testing and certification specifications

• Noise test: Sound pressure level ≤85dB(A) at 1m from the equipment under no-load conditions
• Electrical safety: 500V DC insulation withstand voltage not less than 1MΩ
• Dynamic balance test: Residual unbalance of rotating parts <5g·mm/kg

Health and safety management of process equipment

CIP cleaning system specifications

The CIP design of the fermentation tank meets the requirements of the recovery liquid flow rate ≥1.5m/s, and the three-level alarm is set on the online monitoring interface of the cleaning agent concentration. Typical parameters: 80℃/2% caustic soda solution circulation for 60min.

Key technical paths for standard implementation

Analysis of difficulties in the application stage

• Selection of food-grade lubricants compatible with 225°C sterilization conditions
• Verification of multi-point temperature compensation steam sterilization process
• Dynamic balance deviation compensation of high-elastic couplings such as frequency conversion
