KR-102963486-B1 - Kneader with improved mixing efficiency

Abstract

The present invention relates to a food dough mixer with improved mixing efficiency, and more specifically, to a food dough mixer that uses rotational force to mix various powders used as food ingredients, such as flour, and in particular, allows for the simultaneous dispersion, kneading, and cutting of the powder during the mixing process to produce a stickier dough, as well as to maximize power efficiency by reducing rotational resistance and to minimize the occurrence of dead zones within the mixing container where rotational force does not reach, thereby enabling a more homogeneous dough.

Description

Food kneader with improved mixing efficiency The present invention relates to a food dough mixer with improved mixing efficiency, and more specifically, to a food dough mixer that uses rotational force to mix various powders used as food ingredients, such as flour, and in particular, allows for the simultaneous dispersion, kneading, and cutting of the powder during the mixing process to produce a stickier dough, as well as to maximize power efficiency by reducing rotational resistance and to minimize the occurrence of dead zones within the mixing container where rotational force does not reach, thereby enabling a more homogeneous dough. Typically, food mixers are predominantly rotary mixers that perform mixing by applying rotational force to powder loaded into a mixing container. These rotary mixers can be classified in detail according to the structure of the mixing blades. For example, while a structure with streamlined blades has the advantage of preventing powder from easily adhering to the blades, it has the disadvantage that powder may become stuck or dough may accumulate between the blades, causing a load during the mixing process and placing a heavy load on the power unit, thereby reducing its service life. Furthermore, it is obvious that efficient mixing cannot be provided due to the accumulation of dough, and there was a problem where dough mixing could not be performed uniformly due to the occurrence of dead zones where dough accumulated. As another example, in the case of a structure where the stirring blades extend perpendicularly from the central axis of the stirring shaft, the occurrence of blind spots can be relatively reduced, but there is a fatal disadvantage in that the rotational load is significantly applied to the dough placed in the rotational direction of the stirring blades, and rapid mixing cannot be provided due to the resulting decrease in mixing efficiency, as well as problems such as frequent breakdowns caused by overloading of the power system.

Detailed descriptions of known functions and configurations that are deemed to unnecessarily obscure the essence of the present invention are omitted. The food dough mixer with improved mixing efficiency according to the present invention (hereinafter referred to as the dough mixer) applies rotational force to powdered grain materials such as wheat flour, rice flour, etc., to disperse the powder in the initial stage of dough formation, and when the powder undergoes a phase change into a dough form having appropriate viscosity, it performs kneading and cutting actions on the dough so that the materials are evenly mixed and a homogeneous dough can be produced. To this end, the dough mixer according to the present invention can be broadly defined as comprising a dough container (1) and a dough unit (3). The dough container (1) has a body shape and can accommodate materials to be mixed inside, and the top can be formed open. A dough unit (3) is seated and connected to the open top to mix the materials introduced into the dough container (1). A pipe installation groove (1a) with a grid structure may be formed in the dough container (1), and a steam pipe (1b) may be installed in the pipe installation groove
