Dehydrator automatic timer shutdown circuit

For example, under normal circumstances, a certain dehydrator takes about 5 minutes to dehydrate a load of blank towels. However, it actually shuts down 4 minutes after it is turned on
. Then the inertia of the dehydrator can be used to meet the requirements. However, operators often fail to shut down the machine in time during actual operation,
resulting in a waste of electric energy. For this reason, a 555 time base integrated circuit to automatically shut down the dehydrator motor at a scheduled time to
save electric energy.
