GB/T 33753-2017 in English

This standard specifies in detail the terms, models, technical requirements and test methods of rotary automatic viscous liquid filling and sealing machines (hereinafter referred to as "filling and sealing machines"), which are suitable for the filling and sealing of viscous liquid materials such as edible oils, condiments, and daily chemicals with a dynamic viscosity of $\mathrm{0.03~Pa\bullet s{\sim}10~P a\bullet s}$.

With the rapid development of the food packaging machinery industry, rotary automatic viscous liquid filling and sealing machines are increasingly widely used in production lines. This standard provides unified technical specifications for the design, manufacture and inspection of equipment to ensure that product quality and safety performance meet industry requirements.

Professional terms and practical application cases

Term analysis

• Rotary fully automatic viscous fluid filling and capping machine: Automatically completes the filling and capping of viscous fluids through rotary motion.
• Dynamic viscosity: An important parameter for measuring the fluidity of viscous fluids, which directly affects the design and operation efficiency of the equipment.
• Qualified finished product rate: When the filling and sealing machine is in stable production, the proportion of finished products with qualified appearance quality and filling accuracy is not less than $\mathrm{99\%}$.

Actual application case

Take a beverage production line as an example, when using a rotary fully automatic viscous liquid filling and capping machine, the following conditions must be ensured:

• The dynamic viscosity of the filling liquid ranges from $\mathrm{0.03~Pa\bullet s{\sim}10~P a\bullet s}$.
• The rated voltage and frequency of the equipment meet the on-site power supply conditions, and the deviation does not exceed $\mathrm{\pm10\%}$.
• The compressed air pressure is controlled at $\mathrm{0.6~MPa{\sim}0.8~MPa}$, and the air quality meets the solid particle level 4, water level 4, and oil level 2 standards in GB/T 13277.1.

Equipment selection and configuration

Select the appropriate type of filling and sealing machine according to the production process requirements, focusing on the following factors:

• Filling capacity range: ensure that the equipment can meet the maximum production capacity requirements of the production line.
• Applicable bottle and cap sizes: confirm equipment compatibility to avoid production interruptions due to size mismatch.
• Control system: give priority to intelligent equipment with automation functions and fault alarms.

Daily maintenance and care

To ensure long-term stable operation of the equipment, the following measures are recommended:

• Regular inspection: Check the air circuit, lubrication system and pipeline sealing every month to ensure no leakage.
• Cleaning and disinfection: Carry out CIP/SIP cleaning procedures according to production requirements, especially the electrical components in the filling liquid contact area and splash area must reach the $\mathrm{IP65}$ protection level.
• Lubrication maintenance: Replace the lubricant according to the instructions to ensure the normal operation of the transmission system.

Safety management and training

Operators need to receive professional training and master the safe operation procedures of the equipment:

• Check the effectiveness of the emergency stop device before starting to ensure that an emergency can be responded to quickly.
• Carry out safety drills regularly to simulate equipment failures and emergency handling procedures.
• Establish maintenance record files and update equipment status and maintenance history in a timely manner.
