The maintenance and care of coffee grinders are crucial for maintaining their good performance and extending their service life. Here are some key maintenance tips for coffee grinders:
First, daily cleaning and maintenance
Bean silo and flour outlet
Cleaning of the coffee beans bin: After each use of the coffee grinder, the remaining coffee beans in the bin should be cleared to prevent overnight storage, which may cause the beans to become stale or deteriorate. Use a sponge and detergent to gently wipe the inner walls of the bean curd bin to remove oil stains and dander.
Cleaning of the coffee grounds outlet: Use a vacuum cleaner to clear the openings of the coffee grounds outlet and the grinding chamber to prevent coffee grounds from remaining and causing blockage. For deep residual powder, you can use special cleaning tablets for bean grinders or raw rice for cleaning.
Grinding chamber and cutter head
Grinding chamber cleaning: Regularly disassemble the fixed grinding discs on top and use a brush or air blowing to remove coffee grounds and grease residues from the grinding chamber. For users who are not familiar with the manufacturing of the grinding machine, it is recommended to use special cleaning tablets for grinding machines for cleaning.
Cutter head maintenance: Check if the cutter head is worn or damaged. Replace it in time if necessary. Avoid using hard objects to scratch the cutter head to prevent damage to its surface.
Shell and operation panel
Shell cleaning: Use a soft damp cloth to wipe the shell and operation panel of the coffee grinder to remove dust and stains. Avoid using corrosive cleaners to prevent damage to the surface of the machine.
Second, regular deep cleaning and inspection
Regular deep cleaning
Deep cleaning of the grinding chamber: Depending on the frequency of use, a deep cleaning should be carried out once after grinding a certain amount of coffee beans (such as 25 kilograms). Disassemble the grinding chamber and use professional cleaning tools to thoroughly remove any remaining coffee grounds and grease.
Circuit and motor inspection: Regularly check the circuit and motor connection of the grinding machine to ensure that the wires are not aged, cracked or loose. If any abnormality is found, professional maintenance personnel should be contacted in time for inspection and repair.
Replace the vulnerable parts
Sealing ring replacement: If there is a sealing ring in the boiling head of the grinding machine, it should be checked regularly to see if it is aged, cracked or deformed. If there is any abnormality, it should be replaced in time to avoid affecting the sealing and performance of the grinding machine.
Filter replacement: If the water quality used is poor or the consumption is large, the filter of the grinding machine should be replaced regularly to prevent scale and impurities from causing damage to the machine.
Third, precautions for use and storage
Use correctly
Avoid overloading: Do not put in too many coffee beans at one time to prevent the grinder from being overloaded or damaged.
Choose the appropriate grinding degree: Select the right grinding degree based on the coffee-making method and personal taste to avoid overly fine or coarse grinding that may affect the coffee’s flavor.
Safe storage
Moisture-proof and dust-proof: When the grinding machine is not used for a long time, it should be stored in a dry and well-ventilated place to avoid damage to the machine caused by moisture and dust.
Avoid direct sunlight: The grinding machine should be kept away from direct sunlight for a long time to prevent the surface of the machine from fading or aging.
Fourth, other maintenance suggestions
Regular calibration
Grinding degree calibration: After long-term use, the grinding degree of the grinding machine may change. Calibration should be carried out regularly to ensure that the ground coffee powder is uniform in thickness.
Professional maintenance
Seek professional assistance: If the grinding machine malfunctions or malfunctions, contact professional maintenance personnel promptly for inspection and repair. Do not disassemble or repair it by yourself.
