Abstract
It is proposed that, for the industrial dry peeling of potatoes or similar produce, the potato to be peeled be subjected to a punching operation in such a way that each potato is stripped of its skin at its largest circumference and at that point an oval- cylindrical zone (150) shows and subsequently the potato is peeled in a number of sections and tracks (124, 126, 128, 130, 132, 134, 136, 140) on both sides of that zone cutting operations.

EQUIPMENT AND METHOD OF OP ERATION rCR. T-_. DRY PEELING OF
POTa TCES PVD S.I:vIILAR PRCDUC E.
I general !rrc~ri c,.~ge to ct~.r_p potatoes and similar ~ rCdi: Ce of t s g:_ their outer layer 1n an industrial CCeSS. In this pr~CeSS many types of rolling, scrapi ng, peeling and cutting machines and so forth UtiliZed on a~.ary~e scale that subject the potatoes and similar prociuce to a nt:.-n.ber of operations requirlrig large quantltleS of 'Nater. TheSe operaticns continue until all outer layers and blemished parts have been removed from the potatoes or similar produce. The cuttings, ground together with the water, are removed as a slushy mi:;ture. These operations result in a substantial loss of the potato body. Th4s loss can amount to approximately 60% which results in a significant production cost increase in the peeled potato industry.
Thus the negative feature of the known processes is the large quantities of water uti'_ized which is removed as a slushy effluent and is regarded as a pollutant requiring a costly cleaning process to separate the effluent componerits.
The resulting sludge is considered a waste of little use.
The objective of the invention is to design equipment and methods of operation which in contrast to known peeling Drocesses, can be used without water and the cutting used for productive purposes such as a supplement to cattle fodder. T!ie method of operation for the industrial dry peeling of potatoes shows herewith the features mentioned in claim 1. Through this method of operation the potato to be processed is machine punched to its largest circumference, giving the potato a preferably oval-cylindrical peeled surface through which the ,0 potato shows a reference level in a singular manner for all further ooeraticns. A s'_eeve shaped punch-cutter, that shows the features in claim 2, is used to its advantage. This method cf oceration offers the possibility in a reiatively simple way to subject a sinaularly identified potato to a variety of manipulations to croduce a peeled potato with a mini:-rium o=
waste. Tests ln C'_Cat tnat tne waste produced ,.'~,y t':''.;S

It 13 ~.h us l;ilportarit that the potato is clamped t=,ht in the punc:: cutter yet :re:~ains movable.
According to t:~.e inventicn, with this method of operation the rounded zone obtained by t:ne punching cutter is of a preferably oval-cylindrical shape; this shape is the c?osest match to the average shape of tne potato. The invention is also applicable to other cross-section shapes such as for example an oblong shape with almost parallel zone parts.
The invention also provides for a structure to execute the previously described method of operation. This structure shows the specific details which are identified by the distinguishing marks of claim 2. This structure can be equipped with a stepwise rotating assembly plate with holders for punching cutters and whereby the various means of operation are in a stationary position. Naturally another stepwise movable transporter with holders for punching cutters can a',so be utilized, such as for example a chain transporter with which the holders with _he cutters are moved along a partially linear path.
The invention further provides for the special operating ways of the various means positioned ir. the operating stations for the execution of further cutting and peeli;:g operations. T:n!e are mentioned in the claims and are further explained in tne description hereafter following.

The holder (1) contains a sleeve shaped stainless punching cutter (5) which has an oblong, prefer;;bly ova=, cross section shape and where the sleeve can wall (6) sho,Pls an oval-cy'_ir.dr':cay sizape. The top (7) and also the bottcro side (9) of this pu~:ch cutter are constructed as a'..nife edge. The cutter (5) is attached to the holder (1) through welding the stainless steel tabs (11,13,15 and 17) . The tab walls show cutting edges on their upper and lower sides (19 respectively 20).
Bet,Neen the punch cutter (5), the holder (1) and the aforementioned tabs are four spaces in which plate shaped elements ( 21, 23, 25 and 27) can be moved. T'his will be discussed in more detail in another section.
According to the invention, in its first model a transporter is used which is designed as a rotating, step wise rotatable assembly plate. This type of movement is not a part of the invention and is thus not described in more detail. Or. this assembly plate (39) are a large number of cutter holders (1) of the described type, specifically 24 pieces fitted evenly. The movement structure of the cutter holders (1) is indicated by 41.-Near the periphery (43) of the assembly plate (39) are a large nl.:mber of stationary processing stations positioned, each of which are structured to perform an appropriate procedure. These stations are indicated in figure 4 by 10.1, 10.2, 10.3, 10.4 and so forth.

The in Figures 5, 6 and 7 displayed cutting structure, for use by stations 10.7, 10.8, 10.9 and 10.14, 10.15 and 10.16, contains a spring loaded (80) vertically movable shaft (81). This shaft contains a height adjustable sliding plate (83) which can be fastened with a screw (85). Further there is a jacket (91) bcrdered by f-'ar_ges (87 an 89). Attached to these flanges is a cutting knife. This cutting knife takes a slanted angle with respect to the cer:ter line (95) of the shaft (81) and the direction of movement c: the holders (1). The distance (a) is adjustable with a screw and determines the thickness of the peelings. The shaft (81) is mounted in a housing (82), which is designed in such a manner that the entire cutting structure is movable to process potatoes in every way and manner desired.
The cutting structures in Figures 8 and 9, which can be applied to the s-zations 10.6 and 10.13-3, contain a 'r.c'_der (97) which is rotatable by means of - schematically indicated power source (98) . ln -;:e manner il_..stratea, a kriifeblade ;99) is attached to t'.':e hOldar.

...In position 10.12, the potato, which no has been peeled also on the bottom side, is moved up in tha sleeve shaped cutter by an upward pressing mechanism in such a way that the potato with its peeled rounded zone remains partially within the punching cutter and the outside top portion extends above the cutter.
... On passing the positions 10.13, 10.14, 10.15 and 10.16, the potato is held back the guide track (65), while it is being subjected to the cutting operations of the cuttina units (67, 61, 63, 64) iP. a manner as previously described at the positions 10.6, 10.7, 10.8, 10.9.
