Demand for Compressed Air in Food Industry and Granklin Air Compressor Solution

1. the core application scenarios of compressed air in the food industry

1. Production and processing links

• pneumatic equipment drive:
  • mixing, mixing, slicing, packaging and other equipment rely on compressed air to provide power to ensure uniform processing of food ingredients (such as flour mixing, meat products cutting).
  • Typical demand: Air pressure stable 0.5-0.7MPa, fluctuation range ≤ ± 0.02MPa, to ensure the accuracy of equipment operation.
• Spraying and coating:
  • food surface coating food grade paint (such as candy coating, baking food moisture treatment) need compressed air atomized paint, air purity is required to avoid pollution.

2. Packaging and Conveying Systems

• pneumatic conveying:
  • powdered raw materials (e. g. milk powder, starch) or granular food (e. g. confectionery) are transported through compressed air-driven ducts, requiring low humidity air to prevent agglomeration of raw materials.
  • Key requirement: compressed air dew point ≤ -20 ℃ ensure a smooth delivery process.
• Vacuum packaging:
  • compressed air drives the vacuum pump to extract the air in the package to extend the shelf life of the food. Oil-free air is required to avoid polluting the packaging environment.

3. Cleaning and drying process

• equipment cleaning:
  • high-pressure airflow purges residues on the surface of production equipment (such as flour and oil stains), and requires air to be free of oil and particles to prevent secondary pollution.
  • Standard: compressed air oil content ≤ 0.01mg/m³, particle diameter ≥ 0.5μm ≤ 100,000/m & sup3;.
• Food drying:
  • the drying process of water-based foods (such as vegetables and fruits) requires the assistance of compressed air, which requires low humidity air to accelerate the evaporation of water.

Quality Requirements of Compressed Air in 2. Food Industry

1. Oil-free demand

• industry sensitivity: When food is in direct contact with compressed air, the oil content may cause the following problems:
  • pollution risk oil seeps into the food, affecting the taste and safety, in violation of the National Food Safety Standard.
  • Obstacles to compliance: Export food needs to pass the international oil-free standard certification (such as ISO 8573-1. Level 0).
• granklin solution water-lubricated oil-free technology completely eliminates oil pollution, and the oil content of compressed air is close 0 mg/m³.

2. Drying and Cleanliness

• moisture control: Dew point of compressed air shall be ≤ -40 ℃(water vapor content ≤ 127.34 ppmv), avoid:
  • raw material caking: Moist air causes damp and deterioration of powdered food.
  • Equipment rusting: Metal parts are corroded by condensed water, which shortens the service life.
• particulate filtration through the five-stage filtration system (including activated carbon and bacterial filtration), to ensure that the air cleanliness in line with food-grade requirements.

3. Pressure stability

• process requirements: Spraying, packaging and other equipment need to stabilize the air pressure, fluctuation range ≤ ± 0.01MPa ensure machining accuracy and efficiency.
• granklin technique: The Internet of Things monitors pressure in real time, combined with frequency conversion adjustment, realizes constant pressure gas supply, and reduces equipment idling and energy consumption.

Application Value of 3. Grankering Air Compressor in Food Industry

1. Quality improvement

• food safety guarantee oil-free air to avoid food contamination.
• Equipment life extension: Clean air reduces the wear of pneumatic tools and prolongs the service life of mixers, packaging machines and other equipment.
• Environmental Compliance oil-free design avoids oil emissions and meets green plant and carbon neutral targets.

2. Cost optimization

• maintenance costs: Oil filter and oil replacement are exempted, and annual maintenance cost is reduced by more than 30%.
• Energy consumption reduction: The combination of frequency conversion technology and high-efficiency motor saves 15%-20% energy than traditional air compressors.
• Production efficiency: Stable air pressure and low failure rate reduce downtime and increase overall productivity.

3. Security and stability

• explosion-proof design: In the environment involving combustible dust (such as flour), can be equipped with explosion-proof air compressor, reduce the risk of fire.
• low fever: Water lubrication structure reduces the surface temperature of the equipment and avoids safety hazards caused by high temperature.
