Technical Field

The present invention relates to a shredding machine arranged for shredding meat or meat and vegetable mixtures into small pieces without crushing them for use in various dishes, in particular kebabs and lahmacun.

State of the Art

Shredding machines are preferred for mincing meat in kebab and lahmacun-like dishes. Shredding, unlike turning meat into minced meat, is the process of turning meat into very small pieces without crushing them. In traditional methods, a spring-shaped blade for the shredding process contacted with the meat by the chef by applying force from the ends of the two knives respectively and accordingly the meat is divided into small pieces without crushing.

Although the traditional method has been used for a long time, it is a great disadvantage in terms of both workforce and time. For this reason, various studies are carried out on machines that can perform the shredding process.

TR2019/19251 discloses a shredding bench. The shredding bench is provided oval, and there is a shredding blade at one end of the bench that is rotatably connected to the bench. When the user moves the shredding blade from the handle, the cut meats are poured into the center of the oval counter and the meats can be collected quickly. Although acceleration has been achieved in this device, the cutting process is still manpower dependent.

TR2015/03456 discloses a machine that prepares the meat for use in various types of kebabs. In this system, since meat is obtained in the form of minced meat, the traditional kebab flavor cannot be reached with the meat prepared. TR 2016/11763 discloses a shredding machine. In the invention, during the preparation of the kebab meats, the arc-shaped shredding blades move along the movement duct on the chopping table, and the meats are chopped with the help of the chopping order and then the stripping apparatus are scraped from under the shredding blades and taken through the duct without requiring manual intervention. Although the movement of the shredding blade was tried to be imitated, the desired results could not be obtained.

As a result, all the problems mentioned above have made it imperative to innovate in the relevant technical field.

Brief Description and Objects of the Invention

The main object of the present invention is to provide a shredding machine structure arranged for shredding meats or meat and vegetable mixtures. Accordingly, the present invention comprises a drive group comprising at least one drive element to ensure that a slot provided on a body and said body, a platform provided in the slot and a container on the platform, a blade with its sharp edge directed to the container, a scraper extending towards the bottom of the container to scrape the meat in the container, said platform and the scraper rotate relative to each other and said blade move towards and opposite to the container.

Thus, with said rotary movement, it is possible to shred the meat with a more homogeneous size distribution by preventing some meat pieces from seeing more impact by the blade.

Another object of the invention is to enable the adjustment of the distance between the blade container by means of the adjustment mechanism.

Another object of the invention is to protect the container from external influences during operation and to ensure occupational safety thanks to the protector.

Another object of the invention is to prevent the operation of the drive elements until the protector is completely closed and/or the container is completely placed on the platform thanks to the sensors. An object of the invention is to save energy by means of a shredding machine that can be controlled by a single drive element.

Another object of the invention is to ensure that the blade and platform drive are provided by different drive elements and that they are controlled separately from the two elements.

Another object of the invention is to prevent the meat from being damaged during the process by providing a coating on the scraper.

Another object of the invention is to enable the user to obtain processed meat in different settings with a control unit and input unit controlling the drive elements.

Another object of the invention is to reduce the shredding efficiency by ensuring that the blade is provided at an angle to the base of the container and that the blade is struck at an angle to the meat.

Detailed Description of the Invention

It relates to a shredding machine arranged for shredding meat or meat and vegetable mixtures into small pieces without crushing them for use in various dishes, in particular kebabs and lahmacun.

Referring to Figure 1, the shredding machine of the invention is configured for shredding meats or mixtures of meats and vegetables placed in a container (5) by the preferably linear movement of a blade (92).

The container (5) is arranged on a platform (7). A blade (92) is arranged on the said platform (7). The blade (92) is positioned with its sharp end facing the container (5). A scraper (101) extending into the container (5) is further provided with the blade (92). Although in Figure 1 the blade (92) is shown inside the container (5), the scraper (101) is shown outside the container (5), preferably the blade (92) and the scraper (101) are configured to enter the container (5) at the same time and to exit the container (5) at the same time.

At least one of the said blades (92) and scraper (101) and platform (7) is associated with a drive group. Said drive group comprises at least one drive element (3), preferably a motor providing a rotational output, especially braked motors.

The drive group provides the necessary drive to perform the movement provided by the blade (92) to cut the meat into the container (5) and, preferably, to provide the same movement for the scraper (110). In addition, the drive group further rotates at least one of the platforms (7) and the scraper (100) and provides a relative rotational movement between these two elements relative to each other. With this movement, the meat is kept in constant motion, allowing a homogeneous cut by the blade (92).

In the preferred embodiment, said scraper (101) is provided fixed to the container (5), to its base, except for the movement it makes towards it, and the platform (7) is rotatable by the drive group. Here, the meat taken into the container (5) constantly changes position with respect to the blade (92) by the movement provided by the platform (7) to the container (5), and the scraper (101) is turned upside down in the same way. Alternatively, the scraper (101) can be provided rotating, and the platform (7) can be provided stationary, but where the platform (7) allows the meat to move only with the effect of the scraper (101), which is undesirable.

Here, the scraper (101) is provided so that it almost contacts or contacts the base of the container (5) to provide effective scraping and mixing. Preferably, the scraper (101) is provided parallel to the base of the container (5).

In the illustration in Figure 1, the blade (92) and the platform (7) are moved by a single drive element (3), preferably a motor providing rotational output. Herein, the rotational output of the motor is transferred to the platform (7) with a transfer element (A). Herein, if the transfer element (A) is required, it may comprise elements that will change the direction or axis of movement from the output of the said motor. The movement transmitted from the motor allows the platform (7) to rotate on its own axis.

A lower pulley (82) is connected to the output of the same motor. The lower pulley (82) is associated with a belt (83) or a similar element to transmit rotational movement to an upper pulley (82). The upper pulley (83) comprises another transfer element (A) arranged to convert the rotational movement into linear motion. Preferably, a crankshaft (85) and a connecting rod (86) connected to said crankshaft (85) are used as the transfer element (A). Herein, the transfer element (A) is further connected to the blade (92). Herein, the linear movement allows the blade (92) to contact the meat in the container (5) in a linear manner.

Alternatively, separate drive elements (3) for the blade (92) and the platform (7) may also be used. In this case, the rotational output motors, and the transfer elements (A) may also be used, but also as the drive element (3), for example with linear motors, pistons or the like that give direct linear drive for the linear movement of the blade (92).

Referring to Figures 2 and 3, the shredding machine is configured on a body (1). The said housing (1) comprises a housing (Y) in which to place the platform (7) and the container (5) arranged on the said platform (7). Herein, the housing (Y) can be provided in the form of a recess that extends towards the inner surface of the body (1). In addition, the body (1) also stores the blade (92) and the scraper (101) together with the drive elements (3).

There is also a guide (G) on the body (1). The guide (G) is provided in the form of a longitudinal aperture. Preferably, there may also be a longitudinal rail in the guide (G). The guide (G) is arranged for connecting a protector (K). The protector (K) is used as a cover and protects the meat from external influences during the process by closing the mouth portion of the housing (Y) and prevents the user from inserting his hand into the container (5) during cutting. Here, the protector (K) is slidably connected to the guide (G) or rail. Alternatively, the protector (K) is connected to the body (1) with a hinge, such as a door, and can close the opening portion of the housing (Y) by moving relative to the hinge axis.

Preferably, the protector (5) is made of a transparent material so that the user can see and control the meat during the process.

The shredding machine may also include sensors that detect whether the protector (K) is closed or not. Said sensors may be provided on the guide (G) to which the protector (K) is connected or at points where the protector (K) contacts the body (1) when it is closed. Said sensors form a response that will prevent the drive elements (3) from operating if the protector (K) is not closed, or a response that will allow the drive element to operate if the protector (K) is closed in a similar manner.

As previously described, the shredding machine has a drive group comprising at least one drive element (3). Herein, the outputs of the drive elements (3) in the drive group are controlled by a control unit (KB). The control unit (KB) may further comprise an input unit. From the input unit, users can provide inputs for how long the drive elements (3) can operate and/or how fast these drive elements (3) will operate, and/or how many blades (92) pulses will be hit as a result of the output from the drive element (3) or how many turns the platform (7) will rotate. Accordingly, the input unit may include various keys or a touch screen.

Referring to Figures 3 and 4, said platform (7) is arranged on a container adjustment mechanism (6). The container adjustment mechanism (6) changes the distance between the container (5) and the blade (92) by changing the position of the platform and therefore of the container (5).

The container adjustment mechanism (6) comprises a primary cylinder (61). The primary cylinder (61) is arranged concentrically with the platform (7) below the platform (7). The diameter surface of the primary cylinder (61) has threads perpendicularly provided with respect to the platform (7). Optionally, the primary cylinder (61) can be seated on a lower cylinder (62).

The container adjustment mechanism (6) includes an adjustment cylinder (63) whose diameter surface faces the diameter surface of the primary cylinder (61), and which has a center axis perpendicular to the center axis of the primary cylinder (61). The adjustment cylinder (63) includes peripheral threads provided on the diameter surface to come into contact with the threads of the primary cylinder (61). Said adjustment cylinder (63) is rotatably provided on its axis and is accordingly hosted at its two ends on opposite handles. According to the amount of rotation of the adjustment cylinder (63), the platform (7) rises or falls.

In order to allow the user to easily rotate the adjustment cylinder (63), the adjustment cylinder (63) is connected to a shaft (631), and an adjustment lever (633) is provided at the end of said shaft (631). Said shaft (613) further comprises a shaft cove (632) extending in an axial direction, preferably having a multi-edge section, and correspondingly said adjustment lever (633) will include a protrusion to be placed on said shaft cove (632). Herein, the adjustment lever (632) is provided removably and may also serve as a locking mechanism. The container adjustment mechanism (6) may be configured to allow the adjustment lever (633) to extend out of the side or front surface of the body (1).

Alternatively, said adjustment cylinder (63) is connected directly or via shaft (631) to a drive element (3). The drive element (3) can adjust the height of the container (5) with the movement it provides. Preferably, this drive element (3) provides the drive according to the user input provided via the input unit.

Referring to Figures 2 and 5, it is noted that it preferably comprises a transfer element (A) at the outlet of the drive element (3) driving said platform (7). The said transfer element (A) comprises a reducer (4). The reducer (4) changes the axis of axial movement. A bevel gear (72) is placed at the outlet of the reducer (4). Another bevel gear (72) having an axis of rotation perpendicular to said bevel gear (72) is positioned so that its threads contact the threads of the first bevel gear (72). Herein, the second bevel gear (72) may further comprise another bevel gear (72) that also contacts the threads of the first bevel gear (72). A pinion (71) is provided on the bevel gear (72). The drive threads (73), which extend radially in the outer diameter of the platform (7), are arranged, and said drive threads (73) come into contact. Thus, the movement platform (7) from the drive element (3) rotates.

Referring to Figures 2 and 6, a blade drive mechanism (8) is used to drive said blade (9). Herein, the blade is driven by the common drive element (3), which is also shown in Figure 5. A lower pulley (81) is connected to the output of the drive element (3) selected as a motor providing rotational output and said lower pulley (81) is associated with a belt (83) and upper pulley (82). Thus, the movement from the motor can be transmitted to the upper pulley (82). The upper pulley (82) is coaxially connected to the crankshaft (85) and these two elements rotate together. The shaft part of the crankshaft (85) is bedded by the bearings (84). A connecting rod (86) is connected to the end of the crankshaft (85). The connecting rod (86) and the crankshaft (85) convert the rotational motion from the upper pulley (82) into linear motion. The connecting rod (86) is connected to at least one shredder group (9) having the blade (92).

Referring to Figures 2 and 7, the shredder group (9) is connected to the connecting rod (86) by a blade handle (91). Herein, the blade handle (91) is guided by a blade guide (93) connected to the body (1). There is a blade duct (921) at the end of the blade handle (91). The blade (92) is connected to the shredder group (9) by passing through this duct. Herein, the blade duct (92) presses against the blade (92) with its wings. The blade duct (921) allows the user to quickly replace the blade (92). Referring to Figures 2 and 8, the scraper (101) described earlier is part of the mixer (10). The mixer (10) has a scraper handle (102) and a scraper (101) at the end of the scraper handle (102). The scraper (101) is preferably coated with a polymer, in particular polyethylene, and is thus prevented from damaging the meat and the container (5). Accordingly, the inner surface of the container may also be provided covered with polymer, in particular polyethylene.

The scraper handle (102) is provided to pass through an electromagnet (103). Here, when the electromagnet (103) operates, it pulls the handle (102) towards itself and pulls it out of the container (5). Herein, the control unit (KB) allows the blade (92) and the scraper (101) to be positioned outside the container (5) at the same time.

Referring to Figure 9, in an embodiment of said shredding machine, the blade drive mechanism (8) is arranged to allow the blade (92) to contact the container (5) at an angle.

Accordingly, the crankshaft (85) is arranged to form a crankshaft angle (a) with the floor, i.e., the bottom of the container (5). Accordingly, although the movement transmitted through the connecting rod (86) is linear, the crankshaft angle (a) and the blade (92) contact the meat at an angle. Alternatively, a drive element (3) providing linear drive can be positioned at an angle to achieve the same technical effect. It is further advantageous here to use separate drive elements (3) for the blade (92) and the platform.
