MAGNETIC DRIVEN ONION PEELER
NEW
TYPE OP-120 The technology used in nowadays fruit- and vegetable 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 The Magnetic Driven Onion Peeler operates as follows: - The onions are fed into the hopper and are transported 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.
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 short The 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.
Innovation The 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 components, 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 a technology using super magnetism. It took us three years of dedicated research and development which was subsidized by the European union. The results are impressive.”
Technology FTNON 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.
Quality In 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.
Productivity The 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.
Sustainability
Technical Data
All 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.
The peeler is completely made in stainless steel 304, except motor drives bearings etc. and equipped with fully enclosed bearings. Air connections: ½”. Optional water connection.
