The maintenance points of a coffee grinder when it is working continuously in a coffee shop are of vital importance, as they directly affect the taste of the coffee and the service life of the grinder. The following are some key maintenance points:
First, daily cleaning
After each use:
Clean the coffee bean barn: Pour out the remaining coffee beans to prevent them from deteriorating or developing unpleasant odors due to long-term storage in the barn.
Clean the coffee grounds outlet: Use a brush or air blowing to remove any remaining coffee grounds from the coffee grounds outlet and the grinding chamber to prevent blockage.
Wipe the machine body: Use a clean damp cloth to wipe the outer shell and operation panel of the grinding machine to keep them clean and hygienic.
Daily cleaning
Deep cleaning of the grinding chamber: If the grinding machine is used frequently, it is recommended that after the end of each business day, the detachable parts (such as the cutter head, filter screen, etc.) be disassembled, and the remaining coffee grounds and grease be thoroughly removed with a soft brush or air blowing.
Check the cutter head: Inspect the cutter head for any wear or damage. If necessary, replace it with a new one in a timely manner.
Second, regular maintenance
Weekly maintenance:
Comprehensive cleaning: Conduct a thorough cleaning of the grinding machine, including the body, bean chamber, grinding chamber, powder outlet and other parts.
Calibrate the grinding degree: Conduct grinding tests using standard coffee beans and adjust the grinding degree based on the test results to ensure that the ground coffee powder is uniform in thickness.
Monthly maintenance:
Deep descaling: Depending on the local water quality conditions, deep descaling treatment should be carried out once a month or once a quarter. Special descaling agents or vinegar solutions should be used to remove scale and impurities inside the grinding machine.
Check vulnerable parts: Inspect the wear of vulnerable parts such as the filter screen and sealing ring. If necessary, replace them in a timely manner.
Third, precautions for use
Avoid overloading: Do not put in too many coffee beans at one time to prevent the grinder from being overloaded or damaged. Add coffee beans reasonably according to the rated capacity of the machine.
Choose the appropriate grinding degree: Select the suitable grinding degree based on the coffee-making method (such as espresso, drip filter, French press, etc.) and personal taste.
Keep the machine dry: After each cleaning, ensure that the interior and exterior of the grinding machine are dry to prevent moisture from causing rust or damage to the machine.
Regular calibration: After long-term use, the grinding degree of the grinding machine may change. It is recommended to conduct calibration every six months or once a year to ensure grinding accuracy.
Fourth, professional maintenance and inspection
Regular maintenance: It is recommended to have a professional maintenance and inspection of the grinding machine at least once a year, including the inspection and maintenance of key components such as the circuit, motor, and cutter head.
Timely maintenance: If any malfunction or abnormal noise is detected in the grinding machine, its use should be stopped immediately and professional maintenance personnel should be contacted for inspection and repair.
Fifth, other suggestions
Train employees: Provide training to the staff of the cafe on the operation and maintenance of the grinding machine to ensure they understand the correct usage methods and maintenance points.
Record maintenance logs: Establish a maintenance log for the grinding machine, documenting the time, method and result of each cleaning and maintenance, so as to promptly identify and solve problems.
Regularly replace the cutter head: According to the usage frequency and wear condition, regularly replace the cutter head to ensure the grinding effect and extend the service life of the machine.
By following the above maintenance points, the good performance and extended service life of the coffee grinder during continuous operation in the coffee shop can be ensured, providing customers with a high-quality coffee experience.
