Abstract: A mixer according to the present disclosure comprises: a mixer body including an outer container, a pulverizing blade and a blade driving unit for rotating the pulverizing blade; an inner container unit including an inner container disposed within the outer container, provided with the pulverizing blade, and having a lateral opening formed therein, and an inner container driving unit configured to rotate the inner container; and; and a dewatering unit including a dewatering container which has a dewatering hole formed therethrough and surrounds the inner container while blocking the lateral opening to receive a mixing object in the inner container, and a dewatering container speed change device for changing the rotational speed of the dewatering container, wherein a scraper protrudes from the outer side surface of the inner container to scrape down a blocking-component of the mixing object, which blocks the dewatering hole of the dewatering container.

Abstract: A blender includes a blender body including an external cylinder, a grinding blade, and a blade driving portion rotating the grinding blade; an internal cylinder unit including an internal cylinder, disposed in the external cylinder, in which the grinding blade is disposed, and an internal cylinder driving portion rotating the internal cylinder; and a controller electrically connected to the blade driving portion and the internal cylinder driving portion to control the blade driving portion and the internal cylinder driving portion. The internal cylinder has an internal side surface on which a projection is formed such that blending objects, flowing rotationally while being ground by the grinding blade, are caught.

Abstract: A blender includes a blender body including an external cylinder, a grinding blade, and a blade driving portion rotating the grinding blade; and an internal cylinder unit including an internal cylinder, disposed in the external cylinder, in which the grinding blade is disposed, and having an internal side surface, on which at least one projection is formed, and an internal cylinder driving portion rotating the internal cylinder, wherein the internal cylinder driving portion rotates the internal cylinder with an internal cylinder driving motor in a direction opposing a rotational direction of the grinding blade, and includes a blocking member preventing the internal cylinder from rotating in the same direction as the rotational direction of the grinding blade.

Abstract: A vacuum low-temperature cooker includes a main body having a heating unit immersed in fluid accommodated in an accommodation tub and heating the fluid, a vacuum packaging unit connected to the main body and vacuum-sealing a packaging film, and a control unit installed in the main body or the vacuum packaging unit, and electrically connected to the heating unit and the vacuum packaging unit so as to control the heating unit and the vacuum packaging unit.
