초록 ▼

A pellet warming system includes a charging unit capable of warming a plurality of pellets contemporaneously. Each of the plurality of pellets comprise an internal heating element which resistively heats the body of the pellet from a regulated electrical current that is provided from the charging unit. The charging unit also comprises a controller board with means to control the duration of electric current supplied to each of the pellets as well as means for cycling electrical current to each of the pellets in order to maintain the resistively generated heat. Once heated, each pellet may have comestible goods disposed indirectly thereon through a plate, the pellet maintaining the comestible goods at an elevated temperature for an extended period of time. The charging unit further comprises means for a user to connect their PC to the controller board in order to alter its internal programming and view its operational history.
