Abstract

The invention relates to a domestic machine substantially shaped as a parallelepiped, constructively comprising a hollow space that can be closed at the top, either by a completely closing cover or by a cover provided with a hopper. Within the hollow space suitable fittings for either kneading, extruding or mincing are horizontally mounted as required. Such fittings comprise: a) in the first case a rotatable mixing blade; b) in the second case a rotatable screw with an associated cylindrical chamber, this latter being further provided with suitable dies at its output end; c) in the third case a rotatable screw carrying a bladed knife with an associated cylindrical chamber, this latter being equipped at its output end with suitable plates with holes against which abuts the rotating bladed knife.

Description

The machine and its accessories enabling, in separate operations, the kneading of a domestic or pasta dough, the extrusion of these doughs, and the grinding of meat and similar materials

Technical field

It is well known that today there are a large number of household food processing machines on the market, with both manual and electric drive.

Some of these machines are simple, others less simple, some can only perform one activity, while others can be adapted to perform more than one job by appropriate intervention.

BACKGROUND OF THE INVENTION

Machines containing plain rolls or tubes and machines containing grooved rollers are known in the field of edible dough production, the first type being intended for kneading and the second for producing real food (noodles, strips, patches, etc.)

Also known are machines capable of kneading by mixing, as well as machines which are equipped with accessories and which, due to minor interventions by the user, can drive the individual components and make the pasta ready for extrusion by various suitable matrices.

Another known household machine is a meat grinder comprising a substantially cylindrical housing or chamber, the first part of which is shaped as a hopper, a screw provided with a blade knife at the end, a plate with holes and an end thread ring and a crank for turning the screw. .

SUMMARY OF THE INVENTION

The machine and its accessories according to the invention have been designed in such a way that with a single basic structure, provided with each suitable accessory, it is possible to achieve:

(a) kneading of raw materials (eg flour and eggs),

(b) extrusion of material suitable for use in various forms and assemblies;

(c) grinding meat or other food.

This brings cost savings by providing a single base machine with few elements instead of three different machines, further reducing space requirements, because in confined spaces of the home it is possible to store only one machine and several auxiliary parts instead of three separate machines.

The base machine has a substantially parallelepiped shape with a spacious cavity approximately in the shape of a bath tub. On one of the short sides there is a chamber provided with two outwardly directed openings for receiving a drive crank, the chamber further having a substantially inwardly directed opening for driving active rotating components.

A gearwheel is provided within the chamber to enable driving at two rotational speeds by inserting the crank into one or the other hole in the outer wall of the chamber.

On the other short side of the base structure, i. on the side opposite to the gear drive compartment, a wide opening is provided with two diametrically opposed wide slits for receiving the components of the individual accessories and attaching them with a bayonet lock.

Above the cavity of the base structure, either a full lid can be provided if the cavity is used all over the dough or the lid is provided with a funnel-shaped hopper connecting the mouth of the housing to the exterior, the inside of the housing rotating the extrusion or grinding screw.

Machine accessories intended for kneading raw materials are:

(a) a suitably shaped kneading knife carrying, on the opposite ends of its axis of rotation, a cylindrical pin and a prismatic pin for driving purposes;

(b) a cylindrical insert provided with two flush and diametrically opposed extensions as well as a cylindrical central seat;

(c) a lid to completely close the top of the cavity.

The mixing knife is placed in the machine by inserting a prismatic pin into the drive bore and the cylindrical pin into the middle seat of the insert, the insert being inserted into the corresponding circular opening in the front wall of the machine and fixed there by rotation.

The accessory assembly of the base machine equipment necessary to extrude the just kneaded dough into a mass suitable for use in various shapes and embodiments includes:

(a) a housing having central orifices and end openings, wherein the front of the housing is provided with a strong external thread and suitably positioned projections for insertion into the annular opening of the front wall of the base machine and for connection to the opening with a bayonet closure;

(b) a worm equipped with a cylindrical axle seat formed at the front end and a protruding cross member at the rear end, intended to be received in the front of the housing;

(c) a connecting shaft, with a cross-connector at the front end and a prismatic protrusion at the rear end, intended to be fitted in the rear of the housing;

d) a die (one of many available) provided with a central cylindrical projection acting as a support and centering device for the screw;

(e) a threaded locking ring for fixing the die to the front of the housing;

f) fixing forks for mounting in respective guides located in the front wall of the base structure and adjacent to the flat surfaces of the housing to prevent the bayonet closure from detaching from the housing;

(g) a lid fitted with a funnel-shaped hopper which is connected to its mouth at its lower end.

The accessory kit for equipping the construction of a basic machine for mincing meat and similar materials includes:

(a) a sleeve which is the same as the extrusion sleeve;

b) a screw for receiving in the front part of the housing, provided with a coaxial shaft protruding from its front end and provided with a front part of a cylindrical cross-section and the following part, a prismatic cross-section and carrying a cross insert at its rear end;

(c) a connecting shaft which is the same as that used for extrusion;

d) a blade knife for that section of the front shaft of the screw that has a rectangular cross-section,

(e) a perforated plate (one of the available series) which is scraped by the different edges of the blade knife, with a central cylindrical seat to support and center the screw;

f) a threaded locking ring for fixing a perforated plate which is the same as the ring used for extrusion;

(g) a locking fork which is the same as that used for extrusion;

(h) a lid for a funnel-shaped hopper which is the same as the lid used for extrusion.

The above features will be explained by means of the attached drawings.
