How often should you need to clean the bean grinder? We seem to be cleaning it every 3 days which seems excessive
No brand or model? Okay, general reasons why grinders clog up. Most common I've found is worn out burrs. The plates, depends on composition and usage. Metal plates last longer but not forever. If your grinding thousand pounds of beans don't expect it to last. I've seen massive grinders fail within a month. It all depends on two factors; How much and how fine. Large grind size will increase life and fine grinds wear the burrs out very fast. Especially Turkish settings. Fine grinds also generate a lot of heat. This can cook the coffee again and make it change in flavor. Heat also forces the oils in the bean to coat the burrs and make them dull out which causes more heat. Prolong grinding will also burn out motor.
* Worse case senario; Very oily beans ground to espresso fine. This is usually the case with 'local' roasters. Poor quality beans, extreme roasting (pushing the max on toasting limits), and extreme fine grinds for a particular roast. Fine grinding tends to work on dryer beans. Heavy moisture (under roasted or beans not aged enough to outgas and dry out) will gum up any grinder. Let your roaster know what your trying to do. Otherwise go with a name brand and correct bean for the flavor profile your looking for. Don't expect 5 star espresso from a cheap roast.
* Final, most likely worn burrs needs to be changed out. Off chance the motor is burnt out or starter capacitor needs replacement. If it is the motor or cap, then you need to review your grinding methods as grinder motors are usually tough enough to handle the range of grinds listed in the specs. burning the motor is a clear sign of abuse.
* Have your vendor look at the grinder. They will know right away what's wrong.
