Requirements for air compressor room of food plant

The air compressor room of the food factory shall meet the requirements of site selection, environment, equipment layout, safety protection, air quality, daily management and other aspects, as follows:

1. site selection and layout

1. site selection requirements:

   • should choose a wide, good lighting place, away from the emission of explosive, corrosive, toxic gases, dust and other harmful substances in place, in order to reduce the unit wear, corrosion and the possibility of explosion.
   • The machine room should be set up independently to avoid sharing space with other equipment that may cause pollution or interference.
   • The floor of the machine room should be flat and hard, generally using cement floor, and keep it clean and free of debris accumulation, especially flammable and explosive materials.

2. Layout Requirements:

   • air compressor and post-processing equipment (such as gas tank, filter, dryer, etc.) should be reasonably arranged to ensure the space and lighting required for operation, maintenance and repair.
   • Adequate maintenance space should be reserved between equipment to facilitate routine maintenance and troubleshooting.
   • The air compressor should not be installed close to the wall, and a certain amount of ventilation and maintenance space should be reserved.

2. environmental requirements

1. temperature control:

   • room should maintain a certain ambient temperature, should not be higher than 40 ℃, should not be lower than 0 ℃. Try to control in a lower state, because the air compressor absorbs higher temperature air will reduce the exhaust volume.
   • In the summer high temperature, cooling equipment such as exhaust fan or industrial air conditioner can be installed to avoid excessive exhaust temperature of air compressor due to poor heat dissipation.

2. Humidity and ventilation:

   • the machine room should be kept dry, with good ventilation and fresh air, and try to avoid a dusty, oily and humid environment.
   • The air inlet should be equipped with a filter screen to prevent dust from entering the air compressor, which will aggravate the blockage of the filter element and the wear of the machine head. In humid areas in the south, dehumidifier can be placed in the machine room to avoid short circuit of electrical components.

3. Cleanliness:

   • dust should be cleaned regularly in the machine room to keep the floor and equipment surface clean.
   • It is forbidden to pile up sundries, especially inflammable and explosive articles, in the machine room to ensure the safety of the machine room.

3. Equipment Requirements

1. selection of air compressor:

   • according to the production needs of the food factory and the quality requirements of compressed air, select the appropriate air compressor type (such as oil-free screw air compressor) and specifications.
   • Oil-free screw air compressors can provide high-quality compressed air to meet the strict requirements of the food industry for air purity.

2. Post-processing equipment:

   • configure air storage tanks, filters, dryers and other post-processing equipment as needed to ensure that the quality of compressed air meets the requirements of the food industry.
   • The filter element should be replaced regularly to ensure the filtering effect.

4. safety protection requirements

1. fire prevention and explosion protection:

   • fire fighting facilities such as fire extinguishers shall be provided in the machine room and their effectiveness shall be checked regularly.
   • Pressure vessels such as gas storage tanks shall be regularly inspected by special equipment inspection agencies and shall be used only after obtaining a certificate of conformity.

2. Electrical safety:

   • the electrical system of the air compressor should comply with relevant safety standards to ensure good grounding and prevent leakage from causing danger.
   • Operators should be familiar with the equipment operating procedures, prohibit unlicensed operation.

3. Warning signs:

   • warning signs such as "No Fireworks" and "High Pressure Danger" shall be posted in the machine room to remind personnel to pay attention to safety.

5. Air Quality Requirements

1. compressed air quality:

   • the food factory has high requirements for the quality of compressed air, and it should ensure that the compressed air is oil-free, water-free, dust-free, and odor-free.
   • Compressed air is regularly tested to ensure that it meets the relevant standards of the food industry.

6. Daily Management Requirements

1. inspection and Record:

   • develop a daily inspection system to regularly check the operating status and key parameters of the air compressor (such as exhaust pressure, exhaust temperature, oil level, etc.).
   • Record the inspection results, find and deal with abnormal situations in time.

2. Maintenance and maintenance:

   • regularly maintain and maintain the air compressor, including replacing the filter element, cleaning the cooler, and checking the belt tightness.
   • Establish equipment files to record the model, factory date, installation time, maintenance records and other information of the equipment for subsequent maintenance and management.
