PURPOSE: A food waste disposer is provided to remove water by using diatomite and to minimize the volume of the food waste disposer by obtaining electric energy by solar panels and converted into the same into an AC current in motors for compressing and pulverizing. CONSTITUTION: A food waste disposer comprises a pulverizing motor fixing plate(3), and a compressing motor(2). The pulverizing motor forms the main body. The pulverizing motor for fixing plate supports a pulverizing motor(1). The compressing motor compresses by using power. The pulverizing motor fixing plate is used as an intermediary. The power is delivered to a blade shaft(6) by the pulverizing motor. The blade shaft delivers the power to a blade(8) which pulverizes food waste. Water remaining water after compressing is absorbed by using diatomite.
