Bean grinding method and apparatus, electronic device, and storage medium

A bean grinding method, comprising steps of:

• acquiring a first grinding rate and a total ground powder weight set by a user;
• determining, according to the first grinding rate, a grinding duration corresponding to a second grinding rate, wherein the second grinding rate is a preset known grinding rate corresponding to a pipe residual powder weight and a kinetic energy residual powder weight;
• judging, when a grinding rate of a bean grinding machine reaches the first grinding rate, whether to start grinding at the second grinding rate under a current ground powder weight of a weighing sensor according to the first grinding rate, the total ground powder weight, and the pipe residual powder weight and the kinetic energy residual powder weight corresponding to the second grinding rate;
• and
• grinding at the second grinding rate if grinding is to be started at the second grinding rate, and sending a stop signal to a motor after the grinding duration;
• otherwise, continuing grinding at the first grinding rate, and going back to step of judging whether to start grinding at the second grinding rate under a current ground powder weight of a weighing sensor to proceed.
