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
process is appr--:imate'_y 30 to 35%. further advantage is
considered in _-e less labor .1.ntens.i':e ..reatmeP.t 'Jf _.~.e

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.

to the assembl1 clate of a tran.sporzer. 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

10.3 and so fcrth ;ust as in Figure 4.
... In position 10.1 a potato (2) to be produced is with its
largest iength measurement aimed iP_ the transport dlrectlon of
the holders, placed in the sleeve shaped punch cutter.
... In cosition 10.2 the level of the punching tools are
controlled.
... In position 10.3 the punching tool (47) is lowered by
pressure mechanism not shown in detail. Thereby the potato 4-s
pushed outside the punching cutter over a portion of its height
measurement in such a way that substantial portion of the potato
remains clamped tight in the sleeve shaped knife and the punched
out peeling drops outside this sleeve shaped cutter and lands on
top of the openings in Figure 1 indicated by (21, 23, 25, 27).
... In position 10.4 the peelings, cut by means of cutting edces
(19) of the tabs (11, 13, 15, 17), are removed in four sections
(112, 114, 116, 118) through the openingz (21, 23, 25 and 27) by
peeling removal element, which shows a number of plate shaped
attachments. The plate shaped attachments are indicated in
Figure 1 by a dotted line (104, 106, 108 and 110).
... In position 10.6 the holder has landed under the first
guide track, whereby the pre-punched potato is relocated, in
height direction, in the sleeve shaped cutter and with a section
(120) in all its positions, in which the guide track (51)
functions, is shifted out of the punch cutter over a
predetermined distance. In this position, the potaco is
processed over a conical surface on its lengths ends by the
rotatable cutting structure according to .7ig'ares 8 and 9. I'h e

132) ... The positions 10.10 and 10.11 are reserved cutting
positions.
...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. The peelings that are removed are
indicated respectively by (134, 136, 138 and 140).
... The positions 10.17 and 10.18 are positions for reserve
cutters.
... In. position 10.19, the potato is pushed out of the sleeve
shaped punching cutter by a suitable pressure mechanism (81).
This mechanism can be equipped with additional knives to cut the
potato in two parts (68 and 70).
... In position 10.20, a pressure mechanism is set up, similar
to the pressure mechanism for position 10.19, which is equipped
to divide a peeled potato into four parts (72, 47, 76 and 78)
In the aforementioned description, its is assumed
that the sleeve sftaped punch cuter shows a hollow cylindrical
design up to its cutting edge. Because it is important that the
potato, after the punch o0eratloI'1, ls held tight yet in a
