1. Analysis of abnormal slice quality
1. Uneven thickness: Check whether the blade fixing bolt is loose and recalibrate the slice thickness adjustment device. If the blade wear exceeds 0.5mm, it needs to be replaced immediately.
2. Poor forming degree: The diameter of the raw potato should be greater than 50mm. Fresh potatoes with a storage time of no more than 30 days can achieve the best slicing effect. It is recommended to thaw at room temperature for 2 hours when used in winter.
2. Rust prevention of metal parts
1. Daily maintenance: Rinse with warm water below 60℃ after each use, and food-grade silicone oil maintenance can form a protective film. Do not use strong acid and alkali cleaners.
2. Long-term storage: The relative humidity should be controlled at 45%-65%. It is recommended to place a moisture-proof agent and power on and idle for 3 minutes every month to keep the motor dry.
3. Operation noise control
1. Mechanical inspection: The spindle bearing is filled with lithium-based grease every quarter, and the dynamic balance deviation of the knife disc shall not exceed 0.05g·cm.
2. Installation requirements: The equipment should be fixed on a concrete table with a thickness of ≥5cm. Installing a rubber shock-absorbing pad on the bottom can reduce noise by 15 decibels.
IV. Improved equipment durability
1. Standard operation: Continuous working time should not exceed 2 hours. If the motor temperature exceeds 70℃, it must be shut down for cooling.
2. Purchase suggestions: Give priority to products with 304 stainless steel body and copper wire motor, and check whether there is a CE or GB4706 certification mark.
Regular maintenance and correct operation can significantly reduce the failure rate. It is recommended to establish an equipment maintenance file to record each inspection and repair. For professional repairs, contact the manufacturer's authorized service point to avoid using non-original accessories.
