MAGNETIC DRIVENONION PEELERTYPE OP-120
The Magnetic Driven Onion Peeler operates as follows:
- The onions are fed into the hopper and are trans-
ported up via adjustable fingers. A wiper system
assures that onions are singulated before they are
positioned in cups which move into the peeling
section.
- An operator has to position the onion horizontally
in the cup, after which the onion is topped and
tailed via the topand tail knives that dynamically
follow the shape of the onion. As the onion moves
through the peeling section it is kept in the cup via
an adjustable pressure system.
- An incision cutting mechanism makes a horizontal
incision at the back and at the front of the onion to
ease the removal of the outer skin of the onion.
The depth of the cutting can be set to cut one or
morelayers depending on the required quality.
After the horizontal incisions have been made the
Magnetic Driven peeling wheel takes the onion off
the cup and rotates the onion, completely frictionless,
in a double horizontal Magnetic Driven onion holder.
All rotating, clamping and opening actions of the
Magnetic Driven peeling wheel occur completely
frictionless, based on magnetism, without springs,
belts or other components.
The technology used in nowadays fruit- andvegetable processing machinery is based on classic mechanics. Motion and action inside the machine is achieved by springs, friction drive belts, and other moving components.
All causing wear and requiring frequent maintenance. FTNON Dofra has applied a technologyusing permanent super magnetism, eliminating the use of wires, tubes, belts and springs resulting in a machine running with frictionless components, tremendously reducing the costs of maintenance.
Product description
NEW
While rotating the onion around its own axes, another
incision is made around the entire circumference of
the onion. The incision depth can be regulated so
that either one or more layers can be cut.
A directed jet of air, limiting the air consumption,
blows the cut skins from the onions. The waste is
transported to a waste hopper via a funnel.
The out-feed of the peeler has an adjustable
centrifugal fan, which keeps the loose skins in the
machine and separates them from the peeled onions.
Economic impact
Characteristics in shortThe Magnetic Driven onion peeler has a significant
positive impact on the following cost factors that
determine the economic return of an onion peeler
in his process:
- The yield of the onion peeling process is higher
(up to 90% reduction of onions lost during peeling
due to centrifugal forces in the conventional
peeling process).
- The human labor costs for daily cleaning and
periodical maintenance are less since the Magnetic
Driven peeling wheel consists of far less components
and is thus much easier to clean and requires far
less time to maintain.
- The onions to be peeled can have a far wider
range in diameter without having to adjust the
machine’s setting due to the better processing
control of the Magnetic Driven peeling wheel.
Less time for machine setting, less time for onion
grading results in a higher economical return.
- Components moving with friction (belts, springs,
arms etc.) are replaced by frictionless operating
super magnets which highly increase the reliability
of the machine and give a longer “up time”.
- Machine components are placed with more space
between them, in a more open con-struction,
greatly improving the hygiene of the machine and
the ease and effectiveness of cleaning.
InnovationThe uniqueness of this product lays in the application
of a technology that is completely new. Because of
the application of this new technology machines
can be build and maintained easier with less compo-
nents, are more hygienic because of less components
that are easier accessible, are more sustainable since
permanent super magnets do not wear and run
without friction and the technology is used to replace
components that do wear (springs, belts, moving
components
John de Groot, CEO of FTNON Dofra“We realized that if we wanted to offer our clients a good solution to the inconveniences of today’s machines, we had to look at machine engineering from a complete different perspective. Avoid springs that can break, avoid metal arms that can tear, avoid belts that can stretch, avoid friction that causes wear, reduce the number of components to increase hygiene and make maintenance easier.Quite a challenge. But we have realized huge improvement on all these issues via the application of atechnology using super magnetism. It took us three years of dedicated research and development which was subsidized by the European union. The results are impressive.”
TechnologyFTNON Dofra has developed and applied a
technique using permanent super magnets. Using
this technology Dofra is able to position, rotate,
clamp and release onions in a machine environment,
based on the physical position of the onion in the
machine. Frictionless!! The machine is equipped with
various kinds of super magnets which were researched
by Dofra for a period of three years under subsidy of
the European community. The related technology
of applied super magnetism in food processing
machinery is patented worldwide by FTNON Dofra.
QualityIn the same workspace as before, productivity is
increased by 50% as the capacity of the machine
increased by 50% due to the applied super magnets.
The super magnets that are applied in the onion
holders have been constructed in such manner that
big onions do not get crushed and smaller onions
do not get lost, without leaving deep (holding)
marks in the onion.
The onion that leaves the Magnetic Driven onion
peeler has an identical quality as a hand peeled
onion. For quality aspects on maintenance and
hygiene see Productivity.
ProductivityThe Magnetic Driven peeling wheel works with
6 onion holders compared to 4 onion holders in
conventional onion peelers, increasing the peeling
capacity with 50%. The Magnetic Driven peeling
wheel moves with more onion holders at a lower
rotational speed. This results in a better control of
the onion peeling process with up to a stunning
90% reduction of onions that are lost during the
peeling due to centrifugal forces in the conventional
peeling process. The conventional peeling wheel
in an onion peeler consists of some 600 parts.
The Magnetic Driven peeling wheel consists of
around 150 components. This greatly reduces the
complexity of maintenance and thus the costs of
maintenance. As the construction of the Magnetic
Onion peeling wheel is an open construction with
rounded components and without the conventional
springs and belts it is far more hygienic and easier
and faster to clean.

SustainabilityAll components that move and have friction, such as
friction belts, springs, arms moving on a curve disk,
have wear and require periodical replacement, using
up the earth’s resources. The permanent super
magnets used by FTNON Dofra have a permanent
magnetic field, with no loss of strength, no wear.
The clamps are driven by magnets, opening and
closing the clamps completely frictionless, thus no
wear. The rotation of the onion in the onion clamp
holder is done by magnets, without physical contact,
thus completely frictionless with no wear. If ever a
technology excels in sustainability, it is the super
magnetism technology patented worldwide
by FTNON Dofra.
