    Cleanliness of potatoes determines their success in further processing. While cleaning is not complicated, you must do it correctly for it to be effective. The basis is established by natural laws, such as floating power and specific gravity.

    As a result of our extensive experience, we have developed a technology for optimal water flow, as well as a specific design of the rinse basin. The technique produces a potato that is free of any stones or greens and removes any poor-quality potatoes, which can be processed further without future problems occurrence.

    Cyclone destoner

    The cyclone destoner is used to remove stones and clay shells. Gradients and flow rates determine the optimal result. Among the many distinguishing features of the cyclone destoner are a reliable stainless-steel pump, a 5-mm thick plate steel and a polyurethane layer that functions as wear-resistant material. A practical and reliable system that delivers results with no-nonsense technology. The system is available in different capacities, up to 70 tons per hour.

    Details

    Drum washer

    The drum washer will remove soil, clay, and sand from the potatoes through the principle of mutual friction. Steel strips alternately positioned on the surface of the direct driven drum and on either side contain smooth and trim edges. This means that no unevenness will damage the potato. This washer's excellent access means it's easy to maintain. Naturally, the device also reduces your water consumption.

  • Peeling

    Over the years, Kiremko has become one of the leading specialists in potato peeling due to continuous innovation in this technology. To achieve excellent results when peeling potatoes, Kiremko knows what temperature setting is necessary along with an accurate depth measurement determined to within millimeters. With less peel removed, your process will yield better results.

    All Kiremko peelers are manufactured with the latest technologies, incorporating easy maintenance and easy cleaning, giving them a low energy consumption and robust performance.

    STRATA Invicta

    By offering maximum yields at the shortest cycle time, STRATA Invicta sets a new standard in steam peeling systems. The potatoes are peeled with a blade thinner than any other machine, where only the skin is removed, leaving the cooking rings untouched. Fast, accurate and reliable, the STRATA Invicta® will really steam things up in your potato processing line.

    Details

    Dry Brush Machine

    Dry brush machines are used to remove the potato peel after steam peeling. A rotating brush will make sure that the smooth surface of the peeled potato remains intact. The gear-drive system is strong, durable, wear-proof and automatic to ensure vibration-free, wear-proof and fault-free operation. This will make maintenance episodes extremely short and easy to manage, resulting in minimal cleaning and maintenance intervals.

    Details

    PeelGuard

    PeelGuard is an optical measuring and weighing instrument that detects residual peels and the presence of dark, green or black spots. This machine will ensure optimum monitoring during the final stage of peeling. PeelGuard increases yield of the final product by compensating for changes in peel thickness or peel definition. This way, the results are tailored to your specific needs, therefore making the most of your potatoes.

    Details
  • Cutting

    Producing a high-quality product requires accurate cutting tools. Due to this, Kiremko has made major contributions to the creation of the market standard with the QuadraFlow. The tensioning knives guarantee further improvements in cutting results.

    A revolutionary potato reaper uses an ingenious water pressure guide that allows potatoes to pass through the cutting grid at speeds between 10 and 14 meters per second. The potatoes are oriented in the most efficient direction, so waste and feathering are avoided. Regular shapes and cutting quality can also be ensured this way.

    Potato Sorter

    With the potato sorter, you will be able to sort peeled potatoes using their diameter. The potatoes are sorted depending on their size using conical rollers fitted with increasing pitches and multiple adjusted valves. This working procedure will prevent products from being retained in the sorter and to maintain a smooth sorting process.

    Details

    QuadraFlow

    QuadraFlow's many benefits range from fantastic results on French fries, wedges, and slices, to easy operation and user-friendliness. With an exchanger, the knife block can also be changed in minutes, ensuring great quality and a stable process. Blockages may be removed without stopping the process altogether and any additional tools will not be needed. Thanks to the use of stainless-steel pumps and the use of minimum mechanics, maintenance and water usage have also been greatly reduced.

    Details

    KnifeGuard

    Kiremko KnifeGuard is an innovative knife identification system specifically designed for the QuadraFlow hydro cutter. Using RFID tags, an internal hydro cutter is programmed to detect whether it has the correct combination of the inlet, knife block, and outlet for the selected size of the cut. KnifeGuard keeps track of how long the knife block has been working, guaranteeing the best possible quality of French fries.

    Details
  • Sorting

    With Kiremko, there are a variety of mechanical and optical sorting solutions available.

    Quality improvement, production yield, and customer requirements determine the most effective solution for each specific situation. These factors apply to potatoes as well as cut products.

    Having a variety of sorting options, easy adjustments, and maintenance-free technology assures a reliable and flexible production process.

    Sliver Remover

    This sliver remover will remove as much as 98% of the cutting residue on your product. The stainless steel used for the fabrication of this machine makes it low maintenance and corrosion-resistant. The roller drive has been hermetically sealed on the inside to prevent any contamination. The sliver remover is also constantly adjustable, and its high level of accuracy is determined largely by the diameter and rotation speed of its rollers.

    Details

    Length Sorter

    With the French fry sorter, you can arrange the French fries in one, two, or three layers of different lengths to suit the end product you wish for. The vibration chute is provided with two decks of interchangeable sieves that determine the accuracy of sorting, which can even be exchanged during the process. The imbalance motors are responsible for ensuring that the product is transported and sorted properly by manipulating vibrations within the motors.

    Details
  • Blanching

    A correctly blanched cut product will make further processing more efficient. A blanching process can influence the crispness after frying, the shelf life after packaging, as well as the colour and firmness of the end product. We combine an accurate blanching time and temperature setting with a robust, low maintenance design.

    Our many years of experience have helped us design well-considered and efficient blanchers for various processing lines. These are now exported all over the world and are maximizing tons of potatoes.

    Screw type blancher

    French fries, potato flakes, potato mash, and screw blanchers can all be produced with this type of blancher. We offer a variety of screw blancher types and sizes. Intense pump systems ensure an equal distribution of temperature, and product outfeed can be carried out by a ferris wheel, whether it is driven separately, by a pump, or by a screw. There is a solution that is perfectly suited to each application.

    Details
  • Drying

    It is important to dry the product properly before it is fried. By doing this, you will be able to achieve higher quality, crispier end product.

    The drying process may be carried out with heat recovered from the frying process. The technique combines high quality and sustainability.

    Dryer

    The belt dryer transports the product within a conditioned environment, where heated air provides control and equal drying. Freshly blanched hot product enters the belt dryer where it is dried by air circulation to prepare for the next step in the process. Achieving the right drying degree is a challenging but controllable process. The result will be an even and consistent product outfeed, which is necessary for your frying process.

    Details
  • Coating

    The coating of potato products requires special frying requirements. A complete coating system consists of the batter coating, the preparation of the coating, an efficient application of the coating and an extra fryer with integrated oil filter system.

    Coating has many uses. Various herbs and spices may be added to the batter, allowing different flavours to be applied to potato chips, wedges or slices. With a thin layer of starch, potato chips will remain crisper and hotter for longer. Drive-in restaurants and fast-food chains can benefit greatly from this type of potato chip production.

    Coating preparation system

    With the Kiremko coating preparation system, the batter is precisely prepared and kept in a cool condition in measured batches as required in the production process. A multiple-tank system can ensure ripening, setting, and redistribution of batter if needed. The temperature and viscosity are continually monitored and optimised, and lumps are avoided.

    Details

    Coating enrobing system

    As part of the enrobing system, batter is sprayed onto the product from above, coating it entirely. Using a special belt with bars, products are driven through the coating bath individually. During the process, a coarse conveyor belt contacts the product and scrapes off the excess coating, which thereafter is collected for re-use.

    Details
  • Frying

    Whether producing French fries, potato chips, or pellet snacks, frying is a critical process that requires a consistently high temperature, regular steam discharge, and a short transit time to achieve quality results.

    Kiremko fryers are regarded as a global standard of excellence.

    Our continuous innovation ensures that the technology we offer is keeping up with the most recent market demands, not only to produce a perfect potato product but also to maximise the energy efficiency and sustainability of our operations.

    CORDA Invicta

    The revolutionary design of the Kiremko CORDA Invicta Fryer is the result of 2 years of intense research, development, testing, and consultation with customers. Thanks to its 30% less oil content, 15% smaller footprint, hygienic design, and low-maintenance belt and pump system, the machine reduces oil content and is environmentally friendly. This makes the Kiremko CORDA Invicta Smart, Safe, Strong and Sustainable.

    Details

    EcoMiser™

    EcoMiser™ has been positioned as a green alternative to traditional methods of oil recovery after frying. Using the EcoMiser™, you'll experience the latest advancements in sanitation, noise reduction, and cleanliness, all while minimizing total cost of ownership. Enclosed conveyors with integrated catch pans control oil vapor, reduce noise, and maintain hygiene.

    Details
  • Cooling and Freezing

    After defatting, the potato product is cooled down from approximately 90ºC to 5ºC. To prevent the cooled down product, with congealed oil remains, from clogging together, the cooling tunnel will subsequently drop the loose products onto the conveyor belt of the freezer.

    This is done by means of an overflow point. As a result, the products can be frozen separately from each other within a few minutes, by means of fast-freezing technology. The first step will reduce the temperature back to -1ºC, after which the second step will achieve a final temperature of -18ºC right to the core of the product.

    Cooling-freezing combination

    An insulated casing with a conveyor belt is used in cooling tunnels. Air is blown vertically from beneath the belt through the product layer. Filters are available in several classifications, from normal to ultra-filtered air. Continuous belt cleaning is also available. The tunnel usually has a mechanical cooling system for ambient air, which cools the product even further until it's a few degrees above zero.

    Details
  • Handling

    As potatoes are processed from raw materials to final product, they are transported from machine to machine.

    Each step in the process has its own requirements for transportation. Cooling, weighing, sorting, dewatering, and defatting may also be part of the transport production process.

    KIremko offers a wide variety of applications for product handling and transportation. Vibrators and conveyor belts account for about 15% of the overall cost of a production line, so making the right choice is essential for achieving the best results.

    Product Pump

    As a successor to the VDKK, the VPCK has been specifically designed for the potato and vegetable industries. Thanks to its larger pump housing and fully engineered cast stainless steel impeller, the VPCK meets market needs for less product damage and better efficiency. It is constructed of high-quality electrolytic polished stainless steel, making it durable and hygienic. The most common applications for this technology include potato flakes, pre-cooked and fresh fries, and pre-cooked potatoes.
