    Project in the spotlight: Condenser drying system

    In their new storage for organic products, Maatschap Van Stee in Swifterbant opted for condensation drying 3 years ago. In addition to the lower energy costs, the higher storage yield was also an argument. “If I had to do it over again, I would do it the same way,” says Frans van Stee. The arable farm of Maatschap Van Stee consists of 70 hectares. Frans runs the company together with his brother. 4 years ago they opted for a gradual switch to organic farming. Onions, carrots and potatoes are their main crops. In addition, the crop plan consists of spinach, beans, fodder beets, sweet… Read more

    Potato storage disease control in both theory and practice

    During the summer period, we often remember well how the previous storage season went. Meanwhile, the new harvest is growing in the field and we can still make small adjustments for the coming storage period that will start again in a few months. In addition to the right storage technique, the right use is at least as important for this reason TOLSMA GRISNICH is answering: When and how long to dry in which situation. How quickly can the temperature be brought down? And if diseased tubers are present, how should we handle drying and cooling? In this article, information is given on the most… Read more

    Box filler and tipper combined in one

    Storing 50.000 tons in 3 weeks
 and then everything in boxes too. Then a capacity of 100 tons per hour is the starting point for the box filler. A challenge for our engineers, which ultimately led to a great product for an international potato processor. A combination of these machines is new on the market. By also equipping the box filler with a box tipper, a multifunctional machine has now been created, which means that the machine can be used all year round within the company. To meet the requested capacity of the customer, no fewer than 3 receiving stations have been built, each… Read more

  • Tips to prevent potato sprouting without the use of Chlorpropham

    Tips to prevent potato sprouting without the use of Chlorpropham

    A lot of experience has now been gained in Europe with the new germination inhibitors in the first storage season without chlorpropham. Halfway through the ‘20/’21 storage season, it is now time to draw up an interim balance and look ahead to the rest of the storage season Some batches of potatoes were stored late and cold and it was not easy to dry these batches quickly. Drying has proved almost impossible without the use of heaters. After the batches had dried, the application of the various inhibitors was often started quickly, also because sprout growth could soon be seen on a… Read more

  • Potato receiving and bin installation in Canada

    Potato receiving and bin installation in Canada

    At the end of December, no fewer than 11 containers were loaded and shipped to Canada. The shipment finds its destination in Grand Falls. There, at the beginning of the year, they start the installation work for a Potato receiving- and bin installation, in completely stainless steel. Stainless steel is a great advantage especially in a wet environment, is more durable and requires less maintenance. The process line starts with a receiving bin and an through conveyor. This conveyer exist out of a stable side frame made of bent material that is welded together by bent 3mm profiles. The… Read more

  • Storing carrots: do it well or don’t do it

    Storing carrots: do it well or don’t do it

    Growing conditions have a major influence on the storage result of carrots. Especially the amount of rain and the disease pressure are strongly decisive. The first aspect that will play a role in storage is the product temperature during harvesting. If the harvest takes place at a high soil temperature and humidity, the start of storage will be more difficult. Cooling then takes longer because both the heat from the product and the moisture from the adhering soil must be removed during cooling. Twice the product temperature during storage requires twice as much time to cool down. In… Read more
