A food-processing device for blending and mixing food comprises a mixing vessel, a blade holder, and a motor base. The motor is a high power motor. The device has various safety features designed for the high power motor. The blade holder comprises a safety mechanism that prevents the motor base from operating without the mixing vessel covering the blade. On the surface of the motor base, it has raised area that is complementarily shaped with some recesses on the bottom of the blade holder to align the blade holder and the motor base. It also has a drainage hole that prevents the accumulation of liquid in the well of the motor base. The motor is mounted on the ceiling of the motor housing through a bracket with multiple dampers. The circuit of the motor has soft start and automatic turn off features.

1. A food processing device, comprising: a mixing vessel having a wall;a blade holder with a top surface and a bottom surface, the blade holder capable of being removably attached to the mixing vessel; the top surface having a blade rotatably mounted on the blade holder, a plurality of pin mechanisms, each mechanism having movable pin;the bottom surface having a gear, a recess with a particular shape, and the pin mechanisms; the pin mechanisms being located at a first set of locations on the bottom surface; the pin mechanisms operating across the top surface and the bottom surface, the pins being capable of protruding from the top surface and being capable of protruding from the bottom surface;the gear and the blade being connected through an axis, the axis being surrounded by a plurality of ball bearings, which are confined by a sleeve;a motor base having a bottom cover removably attached, a skirt removably attached, a motor housing with a motor located therein, and a well located on top of the motor housing, the well is capable of allowing the blade holder to be inserted therein;the motor housing having a ceiling and a bottom entrance, the motor being mounted on the ceiling indirectly only through a motor bracket, the motor bracket being mounted on the ceiling through a plurality of dampers; the dampers being located between the ceiling and the motor bracket and located underneath the motor bracket; the motor being connected to a fan at its bottom end and being also connected to an electrical circuit that controls the motor; the fan being located outside the motor housing and below the bottom entrance;the motor having at least 950 watt power;the well having a well surface with a raised area, an impeller, a plurality of actuators, and a drainage hole thereon; the raised area complementarily matching the particular shape of the recess on the bottom surface of the blade holder; the impeller being connected to the motor; the actuators being connected to the circuit and being located at a second set of locations on the surface of the well, and when the actuators are pressed, the actuators close the circuit; the drainage hole being connected to a third location below the motor housing through a tunnel;wherein, when the mixing vessel is connected to the blade holder, the wall of the mixing vessel causes the pin to protrude from the bottom surface; the matching in shape of the recess and the raised area aligns the blade holder and the motor base when the blade holder is inserted into the well of the motor base; and the first set of locations and the second set of locations match when the blade holder and the motor base align, causing the plurality of protruding pins to each depress the actuators individually; and the food processor is capable of automatically being turned on when the blade holder connected to the mixing vessel is inserted into the well of the motor base;the bottom cover comprising a plate and a cup shaped housing, the plate having a plurality of openings thereon, the cup shaped housing being partially located inside the motor housing when the bottom cover is attached to the motor base, and the cup shaped housing substantially isolating the motor housing from the third location, preventing liquid from the drainage hole from entering the motor housing;the skirt being located in between the motor housing and the bottom cover, the skirt being removably attached to the plate of the bottom cover and to the motor housing, the skirt being larger than the entrance to provide mechanical support to the motor base;the circuit having a soft start function and a timer that automatically turns off the motor after the motor has been operating for a predetermined amount of time; the circuit being connected to a switch mounted on the motor base; andthe switch having a released position, a first depressed position and a second depressed position; the released position opens the circuit while both the first depressed position and the second depressed position close the circuit, wherein the first depressed position automatically returns to the released position once the switch is no longer depressed, but the second depressed position stays the circuit closed when the switch is no longer depressed. 2. The device of claim 1, wherein the sleeve is made of stainless steel. 3. The device of claim 1, wherein the sleeve is made of nylon. 4. The device of claim 1, wherein a plurality of gripping members extend from an outer surface of the wall of the mixing vessel. 5. The device of claim 4, wherein the gripping members are ridges. 6. The device of claim 1, wherein a plurality of ridges extend from an inner surface of the wall of the mixing vessel. 7. The device of claim 1, wherein the mixing vessel has a closed top and a bottom opening being capable of removably attached to the blade holder. 8. The device of claim 1, wherein the mixing vessel is capable of removably attached to a plurality of different blade holders, each blade holder having a different kind of blade. 9. The device of claim 1, wherein the pin protrudes from the top surface when the mixing vessel detaches from the blade holder. 10. The device of claim 1, wherein the impeller comprises an outer ring and an inner ring, the outer ring being securely mounted on the well surface of the well, the inner ring rotatably mounted on the well and being capable of coupling with the gear on the bottom surface of the blade holder, driving the gear when the blade holder is inserted into the well. 11. The device of claim 1, wherein the dampers are made of rubber. 12. A system for detaching the mixing vessel from the blade holder, comprising: the device of claim 1;a wrench having, an elongated member having a first end portion and an opposing second end portion,a head region attached to the opposing second end portion, wherein the head region has a top wrench surface and a bottom wrench surface, wherein the bottom wrench surface of the head region has a second raised area, the second raised area being complementarily shaped to the particular shape of the recess on the bottom surface of the blade holder;whereby a user loosens the mixing vessel from the blade holder by applying torque to the elongated member. 13. The system of claim 12, wherein a plurality of gripping members extend from an outer surface of the wall of the mixing vessel whereby removing the blade holder from the mixing vessel is accomplished by the user gripping at least one of the plurality of gripping members with one hand and twisting the elongated member with a different hand. 14.
