Technical Field
The present invention relates to a food grinding attachment for a kitchen machine, which may be a dedicated, stand-alone grinding machine drive, or may be a multi-purpose kitchen machine (e.g. a stand-alone blender) configured as a primary device for the attachment.
Background
Such accessories are well known and are generally made to be driven by an electric motor incorporated into the main device for grinding, for example, meat and related products. These attachments comprise a powerfully fabricated body member which houses a working grinder member, typically comprising a scroll-type elongated screw configured as an extruder, which rotates within a specially shaped cavity within the body member, pulverizes the meat and transports the pulverized meat to and through an apertured end plate attached to the body member. Meat is introduced into the cavity in the body member via the feed tube and is typically pressed into engagement with the screw by a pusher tool which is pushed into the feed tube by a user. Typically, a hopper device is provided for insertion into the open end of the feed tube to facilitate the addition of meat to the grinder.
Accessories of the kind just described work satisfactorily in most respects, and in particular are well suited to handle the large forces and pressures generated within the body during the meat grinding process operations. However, difficulties arise in cleaning the accessory, and in particular, the cavity within the main body, and the present invention aims to facilitate this cleaning without unduly compromising the ability of the accessory to withstand the forces generated in the above-described operation.
Disclosure of Invention
According to the present invention there is provided a food grinding attachment for connection to a rotary drive outlet provided by a main device; the accessory includes: a main body part having a substantially tubular hollow portion for connection to a main device; a rotatable scroll-type extrusion tool rotatable within a cavity formed within the tubular portion of the main body member and equipped with a member that engages with the rotary drive outlet when the main body member is connected to the main device; means for enabling food to be introduced into the cavity within the tubular body portion and engaged with the extrusion tool for grinding and delivery towards the outlet port of the accessory; wherein the body member comprises a first part and a second part, the first part being separable from the second part and configured to be secured together to operate the accessory, and wherein the parts are adapted to be separable from each other to provide access to the cavity for cleaning.
In some preferred embodiments of the invention, the first and second members are configured to be slidable relative to each other in a direction substantially parallel to the axis about which the extrusion tool rotates; said slidable movement of said parts is performed in one direction to fasten them together and in the opposite direction to separate them.
In other preferred embodiments of the invention, the first and second parts are hingedly mounted to each other. In these cases, the hinge arrangement may be configured to apply pressure to the joint between the components.
Preferably, the abutting edges of the first and second parts are formed using a connecting member by means of which the two parts are securely locked together. In some such embodiments, the connecting member includes a mating tongue and groove configuration.
In some preferred embodiments, the first and second components also have respective portions of external threads for engagement with internal threads of a nut that secures the components together.
In some preferred embodiments of the invention, the joint between the first and second components is provided with a sealing member adapted to resist liquid being squeezed through it. Alternatively or additionally, the joint may be a labyrinth configuration.
The invention also covers a dedicated, independent grinding machine drive with an attachment according to any embodiment of the invention. The invention also encompasses a stand mixer with an accessory according to any embodiment of the invention.
The invention extends to an accessory substantially as described herein with reference to and/or as illustrated in the accompanying drawings. The invention also extends to a stand mixer substantially as described with reference to figure 1 and/or as shown in figure 1.
The invention extends to a method and/or apparatus substantially as described herein with reference to the accompanying drawings.
