A partnership that forms the basis for innovative solutions

For many decades now, GMF-Gouda has set the standard for industrial steam peeling lines and drum dryers. We have been able to do so because of our commitment to the industrial process and the product to be processed, the high degree of specialization of our engineers and technicians, and our extensive process knowledge. GMF has the capacity to develop a suitable solution for the process situation concerned, a solution built up from standard, practically proven components. A solution developed in part in our own test laboratory, where existing and new processes are subjected to pre-production testing to ensure that the desired end result will be achieved. A primary objective during development and engineering is that all process requirements be met exactly. Important aspects such as reduction of energy consumption and waste water, food safety, hygiene, automation and reduction of maintenance costs form the basis for the entire development process. And time and time again, fundamentally new solutions are found that meet the requirements of the customer and the environment. In the future too, the GMF technicians and engineers will be able to help you with the most innovative technologies. A bundling of strengths, expertise and experience that will result in a efficient, structured partnership.

New requirements yield new applications

From the moment our peeling equipment first rolled off the production lines, leading food processing companies around the world have opted for the robust, high-quality machines from GMF-Gouda. Originally, our equipment was developed for potato processing. Now, however, following research into new applications, optimization of the processes involved, and extensive testing in our pilot factory, our products can be found in many process lines of other kinds, where their qualities are highly valued. Today, GMF peeling lines are used primarily for the industrial peeling of potatoes, vegetables and fruit. Our equipment is, however, also highly suitable for shellfish and for the sterilization of herbs, spices and cocoa beans.

Significant cost savings and a short pay-back time

Peeling equipment from GMF-Gouda is characterized by high efficiencies and extremely short pay-back times. In most cases, the investment is recovered in full within one year. Furthermore, less peel waste means more end product per tonne input, a lower energy consumption and lower waste water costs. These cost savings and higher peeling efficiency are entirely due to the technically advanced methods applied in the manufacture and operation of the Sepa-Stator steam peeler and the Brush-'n-Belt dry peel remover. These unique machines, developed entirely by GMF-Gouda, differ considerably from traditional systems, which GMF abandoned at the beginning of the 1990s. In combination, the Sepa-Stator steam peeler and the Brush-'n-Belt dry peel remover provide the results you seek, namely minimal heat ring, substantially reduced waste water and water consumption, substantially reduced steam consumption, and peeling qualities that are significantly less dependent on the quality of the raw product.

There are other advantages too. For example the fact that all the tubers receive exactly the same treatment, both in the steam peeler and the dry peel remover. The higher dry matter content of the peel waste is also a plus point. When you consider all these advantages in terms of overall efficiency, you will understand why most companies recover the costs of their GMF-Gouda equipment within one year. In fact GMF-Gouda even guarantees - in writing - an efficiency at least 1% higher than that of all other manufacturers' peeling lines.

Your product is in good hands

To give you a better idea of how GMF-Gouda approaches the treatment of your product, we will now describe a typical GMF-Gouda peeling line. The process starts with the feed conveyor, which feeds the washed, destoned product to the filling hopper. The product is weighed and passes to the Sepa-Stator steam peeler. The unique thing about this steam peeler is its stationary cast steel pressure vessel. During steam exposure the product is permanently kept in motion in the pressure vessel with the aid of a specially formed agitator arm. Condensate is collected via a grid at the bottom of the pressure vessel and then removed. The highly uniform motion of the product in the pressure vessel and the removal of the condensate mean that each individual product item undergoes exactly the right steam treatment. The total exposure time can thus be reduced to the absolute minimum. The GMF-Gouda steam peelers have capacities of between 3 to 40 tonnes / hour. Rapid pressure drop After the product has been steam-treated, the pressure is reduced extremely rapidly with the patented GMF-Gouda "Ultra Blast Exhaust Valve". The consequence is the peel explodes from the product surface and the product is carried out of the pressure vessel to the outlet screw. This outlet screw equipped with a variable-speed drive, and the product is transported very smoothly to the next processing step. Having left the pressure vessel via the outlet screw, the product is transported, with the peel almost completely detached, to the Brush-'n-Belt dry peel remover. At the dry peel remover, the peel waste is removed from the product in a dry process by brushes and the adhesive action of the belt. The peel waste is removed by a scraper and then fed, in puree form, by the removal pump to a storage tank [whilst]. And the "clean product" is transported to the drum washer for final treatment. The final sticky layer is removed and the product is ready for further processing. The very brief, intensive steam treatment maintains product quality and the short retention time allows large quantities to be processed. Dry and wet designs Depending on the circumstances and your individual requirements, the expansion vessel used in this process can be supplied in either a dry or a wet design. Most of our clients choose the dry design, which works according to the cyclone principle and exhausts the clean steam into the atmosphere. In contrast, the wet design requires cooling water. Waste water is often used for this. In neither design are polluted particles exhausted through the chimney. Simple operation GMF-Gouda peeling lines are characterized by their simple operation. This is thanks to, inter alia, the electric control box with PLC, the completely automatic filling weight measurement, and the integrated automatic control using signals from the process. The cycle times can be set as desired with the aid of the touch-screen display which constantly shows the process parameters. A further advantage is that the apparatus can be easily accessed for maintenance and servicing. However, the choice of materials used and the robust design mean that the service intervals are kept to a minimum, and GMF-Gouda can guarantee downtimes that are only a fraction of a percent. In addition, the equipment is easy to clean and complies fully with the most recent directives on HACCP and EHEDG.

Commitment to client and technology

From raw product to end result. With this theme in mind, GMF-Gouda develops its standard peeling equipment into a client-specific solution. A solution based on a complete peeling line, comprising, inter alia, a Sepa-Stator steam peeler, a Brush-'n-Belt dry peel remover, and an afterwasher. Together the Sepa-Stator and the Brush-'n-Belt provide an unparalleled peeling efficiency. The product is subjected to an intensive yet extremely short steam treatment with intermediate condensate removal. The result is a minimal heat ring, low water pollution and consumption, high dry matter content of the peel waste, and minimal peel loss. In other words, a perfect peeling result. The process takes place at steam pressures as low as 4 bar. The Sepa-Stator steam peeler and the Brush-'n-Belt dry peel remover, which we developed ourselves, are protected worldwide by eight patents. They are the result of innovation coupled with increasingly strict customer requirements and statutory regulations, the fruit of a single-minded search for new methods and technical applications.

Flake lines to complete your production process

An equally important component of the potato processing plant is the flake line. The drying section of the flake line comprises a ricer, feed conveyor, drum dryer, flake transport and mill/sifter, with which flake sizes of 4 - 10 mm can be obtained. The drum dryer, with standard capacities of 100 - 650 kg flakes / hour, is a central component of the process. Building on the experience gained over the last century, GMF-Gouda supplies flake lines of unparalleled quality and efficiency. This is thanks to: Intelligent designs, which prevent mechanical damage and product contamination High drying capacities due to: - a special cast iron drying drum which providesgood heat conduction; - optimal configuration of drying drums and applicator rolls; - close-tolerance manufacture; - special designs for potato processing. Long service life of, typically, 30 - 50 years Low energy consumption of approx. 1.2 - 1.5 kg steam / kg water evaporation
