Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a household mixing and extruding device for general raw food dough.

Conventionally, in this field, when preparing foods such as dough at home, the ingredients, namely flour, water, and/or eggs, are mixed in a machine and the mixture is made into a dense powder.
Finish until an elastic food mass is obtained, then transfer the food mass onto a perfectly smooth surface, roll it out using a rolling pin until it becomes a thin sheet, and continue rolling. It is cut into the desired shape and size using an ordinary knife or using an appropriately shaped tool according to the desired shape.

To date, various attempts have been made to mechanize the home cooking of foodstuffs as described above, in order to reduce the labor expended by workers, shorten working time, and without sacrificing quality. It has been done.

In particular, various manual or motorized devices have been proposed for obtaining a final product with a desired shape and dimensions from a previously separately prepared dough.

These known mechanical devices mainly consist of at least two rolling rollers, which rotate in opposite directions at a constant distance from each other, into which a pre-conditioned formulation is artificially introduced. The sheet is brought into contact with the roller, and the shape of the sheet is determined at that time.

The sheet thus formed is then fed to a similarly suitably shaped roller mechanism where the sheet is cut into the desired shape and size.

To produce food products such as dough, it is now possible on an industrial scale to both formulate the dough and form the final product in one mechanical device without the need for any human intervention. is being done.

The reason why it is possible to do something like this is
This is because the shaping of the product takes place by ejecting the dough into an extrusion cylinder which is connected to the bottom of the mixing bowl.

The main feature of this industrial-scale process is that, beyond the production speed issues stemming from the fact that it is possible to obtain the final product without going through an intermediate step for forming the sheets,
Dough products of all desired shapes, including tubular products such as noodles, macaroni, spaghetti, etc., can be obtained by mechanical production, which is not possible with conventional mechanical equipment in the field of art; That's what it means.

However, it is not possible to transfer the technology that has hitherto been adopted for industrial-scale production to domestic use, since the operating conditions would be substantially changed. It had not been done.

In particular, domestic machinery is obviously limited in volume due to the reality that only small amounts of final product are generally required, and therefore the mixing of dough and the power required during the extrusion process, usually employed in industrial machinery, both for preparing the dough and for transferring it from the mixing bowl to the extrusion cylinder; It has not been possible to generate such power in domestic machinery as is required for thorough mixing of the dough in the extrusion screw.

The present invention is a household device, which is a single mechanical device, and
It makes it possible to both formulate the dough and form it into the desired shape and dimensions with a minimum of power, thereby eliminating the difficulties associated with such processing in general, and in particular the dough The purpose of this invention is to overcome the difficulties involved in feeding the mixture from its mixing vessel to an extrusion device.

According to the present invention, there is provided an apparatus for blending and extruding all types of raw foods such as dough, a means for blending a dough mixture, and a dough in a desired shape and size without going through an intermediate step. extrusion means are provided.

The above-mentioned mechanical preparation means for preparing dough mixes and prepares the various materials, and also applies a thrust action to the prepared dough so that the dough is formed into a desired shape and size. is configured to be transferred to the extrusion means for extruding.

More specifically, the mechanical device according to the present invention is provided with one or more mixing blades as a dough mixing means, the mixing blades rotating on a vertical axis within a cylindrical mixing bowl, It is inclined at an angle to the bottom of the mixing bowl, which angle is acute to the direction of rotation of the mixing vane.

The blending means is also connected to an openable and closable communication opening between the bowl and the extrusion section, and the dough extrusion means is disposed in the hollow cylinder opposite the terminal extrusion port. It consists of a rotatable spiral body/screw.

This extrusion port is replaceable, and the extrusion hole provided in the extrusion port can be formed to obtain a predetermined shape.

A further feature of the invention is that the communication opening between the mixing bowl and the extrusion cylinder is provided with a slidable sliding member for keeping both parts separated during the mixing stage of the dough. It is that you are.

The opening in the mixing bowl for feeding out the dough has a mixing and
A downward protrusion is provided on the opening edge on the opposite side (far side) as seen in the rotational direction of the thrust means and integrally with the mixing bowl.

In other words, this protrusion has a thicker wall near the opening edge, and the dough hits the protrusion and is more smoothly delivered to the extrusion cylinder below.

According to another aspect of the invention, the transfer of the blended formulation in the mixing bowl to the extrusion unit is made more efficient and consumes less power, resulting in higher production efficiency. It will be done.

This advantage can be completely obtained by separating, in the mixing and thrusting means, the function of mixing the materials and the function of forcing the prepared formulation through suitable openings into the extrusion unit.

In detail, the mixing member consists of a preferably helical mixing blade that projects in the vertical direction, and rotates on the vertical axis in the bowl together with a spinner inserted into the rotating shaft of the electric reduction gear. It is further characterized in that the spinner is provided with a thrust member consisting of an auxiliary radially inclined vane made of elastic material.

The mixing of the materials is therefore carried out by a rotary movement of the mixing vanes, preferably having a helical shape, and the prepared mixture is forced into the sliding opening by means of radially inclined vanes. However, due to the fact that the inclined vanes are made of elastic material and are therefore suitable for absorbing part of the resistance provided by the formulated dough itself, the power therefor is significantly reduced. 《It is something that can be alleviated.

In addition, the sides of the mixing bowl are provided with several ridges, preferably of circular cross-section, suitable for cooperating with the mixing vanes to ensure optimal mixing of the above-mentioned materials. Alternatively, a protrusion may be provided.

Finally, to mention a further characteristic point, the mechanical device according to the present invention has a mechanism in which the rotation of the mixing blade and the thrust blade and the rotation of the extrusion screw are controlled by a twin take-off shaft (twintake-off axis).
It is characterized by being driven by a single motor connected to a suitable reduction gear having a shaft.
