Daily Operation & Maintenance Instructions for Continuous Frying Production Line

Equipment Operation Sequence:

 
  1. Cleaning: Remove hard objects and residues from the fryer pot and pipelines.
  2. Trial Run: Start the residue scraper belt, upper and lower mesh belts, lifting mechanism, fume exhaust fan, and circulation pump in sequence. Check the rotation direction, jamming, and oil leakage.
  3. Oil Filling: Thoroughly remove water, hard debris and residues from the pot and pipelines before adding oil. Fill oil to 30–50 mm above the lower mesh belt (adjust according to actual products).
  4. Heating: Ensure the oil level fully covers the lower mesh belt before heating.
  5. Operation: Turn on the temperature controller, set the frying temperature as required. Start production only after reaching the set temperature.
  6. Start the fume exhaust fan, residue scraper belt, upper and lower mesh belts, and circulation pump in sequence.
  7. Check pipelines and valves for leakage. Start the circulation pump before normal production.
 

 

Special Safety Notes:

 
Operation: Never leave the equipment unattended during operation. Cut off the main power supply when leaving.
 
Oil Filling: Do NOT turn on the heating elements if the oil level is below the required position.
 
Coarse Filtration: Lift and clean the filter every 30 minutes according to residue amount.
 
Residue Box: Empty immediately when full. Residues must not stay inside the equipment for more than 1 hour. Cool filtered residues completely in water and keep away from equipment.
 
Scraper Belt: Keep running for 15–30 minutes after production to remove most residues.
 
Lifting Mesh Belt: Turn off heating after frying. Lift the belt bracket only after 30 minutes to prevent residue ignition from residual heat.
 
Safety Pin: Insert the safety locking pin fully after lifting the equipment before any maintenance.
 
Fire Suppression System: After removing the solenoid valve safety pin, do NOT cut off the fire extinguisher control power after frying. Operate according to the extinguisher manual.
 
Electrical Safety: The equipment casing and electric control cabinet must be reliably grounded. Regularly check the temperature controller sensitivity and electric components for heating elements.
 

 

Daily Maintenance:

 
  1. Tighten all bolts weekly, especially AC contactor terminals, chains and screws.
  2. Do NOT use strong acid or alkali to clean the frying equipment.
  3. Clean the equipment every two weeks. At least two persons must be present during cleaning; ensure no unattended operation.
  4. After production, turn off control switches. Fill cool oil to lower temperature below 130°C, wait 20 minutes, then lift the mesh belt and drain all oil.
  5. During cleaning, raise the upper cover and mesh belt to the designated position and insert the safety pin before cleaning.
  6. Inspect and clean the exhaust duct monthly to ensure unobstructed ventilation.
  7. Clean the oil tank thoroughly to ensure no water in the oil tank and oil discharge pipe for each use.
  8. Cleaning Method: Fill with water, add edible alkali or detergent, heat to about 50°C, run the mesh belt continuously for 60 minutes. Clean oil stains on the mesh belt, support and inner pot with a soft brush. Rinse attachments with a water spray gun.
  9. Do NOT spray water on the electric control cabinet or heating elements. Clean the control cabinet monthly to prevent short circuits.
  10. Clean the equipment completely if not used for a long time.
  11. For long-term shutdown: heat oil to 170°C and run equipment for more than 10 minutes every 15 days.
     
    Heating elements must not be soaked in water continuously for more than 10 hours.
