The daily maintenance of frozen meat slicers (such as commercial meat slicers and meat grinders) is crucial for equipment lifespan, cutting efficiency, and food safety. The following is a detailed maintenance process and precautions:
1. Clean after daily use
(1) Power outage and disassembly
Turn off the power, unplug the plug, and ensure safety.
Disassemble detachable components: blades, cutterhead, meat tray, protective cover, etc. (operate according to the instructions).
(2) Cleaning steps
Blade and disc:
Soak in warm water and neutral detergent, wipe with a soft cloth to avoid scratching the blade with hard objects.
Stubborn fats can be soaked in food grade degreasers (such as alkaline solution) and rinsed.
Body and meat delivery system:
Wipe the surface oil stains and meat residue with a damp cloth, focusing on cleaning the meat delivery track and gear gaps.
Do not directly rinse the motor part with water to prevent short circuits.
disinfect
Spray the contact surface with 75% alcohol or food grade disinfectant, let it stand for 3 minutes, and then dry it.
(3) Drying and rust prevention
All components should be thoroughly dried or dried to prevent rusting.
Stainless steel components can be lightly coated with food grade lubricating oil (such as mineral oil) to prevent oxidation.
2. Blade maintenance and replacement
(1) Daily inspection
Sharpness: If the cutting is uneven or the meat pieces are stuck, it is necessary to sharpen the knife or replace the blade.
Blade status: Check for gaps, curled edges, or cracks to prevent the risk of breakage.
(2) Sharpening method (applicable to grindable blades)
Use a specialized sharpening stone or sharpener to evenly polish at the original factory angle (usually 15 ° -20 °).
Remove metal debris after sharpening to avoid contaminating food.
(3) Replace the blade
Disassemble the old blade according to the instructions, and pay attention to the direction when installing the new blade (with the blade facing correctly).
Tighten the fixing screws to ensure no looseness.
3. Mechanical system maintenance
(1) Lubrication and maintenance
Gears and transmission components: Add food grade lubricating grease (such as white lithium grease) every month.
Bearings: Check, replenish or replace lubricating oil every 3-6 months.
(2) Belt/chain adjustment
Check the tightness of the belt. If it is too loose, it will cause slipping, and if it is too tight, it will increase the load on the motor.
The chain needs to maintain moderate tension and be adjusted or replaced if necessary.
(3) Motor maintenance
Regularly clean the motor cooling holes to prevent dust accumulation and overheating.
Monitor the running sound, abnormal noise may indicate bearing wear or loose components.
