The present invention relates to an apparatus for making potatoes of various sizes and shapes for use in restaurants and canteens - Anordning for the production of potatoes of different sizes and shapes for restaurant and canteen use and for canteen use. An example of a potato shaped in this way is a spherical Parisian potato, which will hereinafter be used in this specification as an example. However, the invention is not limited to the production of a spherical potato, as long as the shape is such that it can be processed using rotating blades.

The design of Parisian potatoes can take place with a variety of devices, all of which have significant drawbacks. They are essentially too slow for modern industrial processing. First, a Parisian potato can be made by hand using a cup-shaped tool to engrave one or more cups the size of a cup from a large-sized potato. In this case, the percentage of potato wastage is high and the amount of handicraft is very considerable.

The spherical Parisian potato can also be produced by grinding equipment, but the quality of the product obtained varies and the production costs in this case are very high, and the wasted part of the potato can generally not be used in any way.

A method and apparatus for the mechanical production of Parisian potatoes are also known from Finnish patent publication 63664. The device disclosed in this patent has certain similarities with the principles of the present invention, e.g. the Parisian potato is processed using a rotating tool from the starting product and a ring-like part remains in the holding holder, but the device 70706 according to said patent is still relatively slow compared to the present device and the investment costs are substantially the same, the cost of the method according to this known patent is thus unnecessarily high.

It is therefore an object of the present invention to provide an apparatus for producing Parisian potatoes from a small-sized raw potato with high efficiency. The object of the invention is to be able to overcome the disadvantages caused by the slowness and high cost of previously known devices and to enable a particularly efficient apparatus and consequently an inexpensive method for producing potatoes of different sizes and shapes for restaurant and canteen use.

In order to achieve these objects of the invention, the apparatus according to the invention is characterized by what is set forth in the characterizing part of claim 1. This combination contains various factors and the combination of these can achieve the desired result compared to the prior art.

Preferred embodiments of the invention are set out in subclaims 2-5.

An important advantage of the apparatus according to the present invention is that a small-sized potato, which would otherwise have no economic use, can be used as a raw material.

With the apparatus according to the invention, potatoes of different shapes and sizes can be provided by means of a shaping unit 8, into which the potato blank is fed one by one to the workpiece 5. For this workstation, the potatoes are fed by a metering wheel 1. There is an exchange point 4 between the metering wheel 1 and the impeller, where the potato enters the gripping member of the impeller, leaving the cup-like part of the metering wheel.

706 6 6 3

Before the potato arrives at the exchange point, there are adjustable cutting blades 3 on the sides of the metering wheel 1, by means of which the excess part is removed from the sides of the potato and a diameter slightly larger than or equal to the length of the final desired piece is obtained.

Potatoes can be fed by means of a metering wheel 11e with the aid of various feeding basins. In the shaping unit, a part of the desired shape is cut out of the blank and this machining step will be described in more detail below, after which the finished part is removed to the discharge chute 11e on the side of the work circle using a suitable removal member. This removal member can be mechanical, but very fast operation can be achieved by using compressed air blowing.

An annular portion of the blank remains on the workpiece, which is then removed from the workpiece in the next step using a separate removal lever.

In particular, the invention can be illustrated by means of a preferred embodiment thereof with reference to the accompanying drawings, in which Figure 1 shows the apparatus seen from the front. Fig. 2 shows the apparatus in a side view, i.e. as in Fig. 1, viewed from the right.

The starting potato is fed from the feed silo to the metering wheel 1, where the holder or transfer cam 2 moves the potato, cutting off both sides before the transfer point, by means of separate blades 3. After this cutting, the potato arrives at the exchange point 4, whereby the transfer cam 2 moves away from the potato, releasing the potato onto the working ring 5, where the cam 6 locks it against the member 7.

This perimeter and the perimeter holding the shaping cutter blades move forward at the same speed and during this rotation the blades 8 of the shaping unit process the potato in its specified 70666 4 processing step. At the end of the movement, a blank of the desired shape is formed from the blank and a ring-shaped residue is left out.

The shaping units 8 obtain their axial movement required for machining from a suitable control element, e.g. an eccentric wheel. Under the influence of these institutions, the shaping units 8 move in opposite directions of the wheels at the same time. This rotation in opposite directions is advantageous, since the potato to be produced is then subjected to the smallest possible joint force which releases the grip in the blank.

There are, for example, four pairs of shaping units on the impeller. These pairs of blades each in turn process their own potatoes at the same stage of the movement of the wheel under the control of the control unit. After shaping, the finished product leaves the workpiece on a separate removal chute, which can thus be located with respect to the transfer movement at the destination. This removal point is followed by the removal of the annular portion of the potato blank to the side of the work circle.

The mechanical details of the structure, e.g. the provision of rotational movement by different machining blades 11e 8, the gripping movement of the potato gripping cams 6 and 7 and other similar details, are likely to be easily obtained by a person skilled in machine design. As a result, no further attention has been paid to them in this patent specification.

However, some details can be extracted from the structure of the device, as they are capable of providing an efficient and consequently usable unit.

First, the dispensing wheel 1 can be formed as can be seen in Fig. 1 from three parallel plate-like parts, whereby in Fig. 1 only the outermost plates 1 'are more clearly visible with the central plate 1 "in the center of them. m. off.

Dosing can be made very secure and simple by placing more of these dosing cams 2 in the dosing wheel than there are impeller holders. In this case, the circumferential speed of the metering wheel can be made lower than the transfer speed of the machining holders. Correspondingly, the metering wheel then acts more reliably, lifting the potatoes from the feed tray to the impeller.

It should be noted that with respect to the shape of the Parisian potato to be prepared and other details of the apparatus, they may vary within the scope of this invention in a number of different ways that any person skilled in the art can obtain from this description and the appended claims.
