For potato growers, maintaining the quality of the potato during storage is essential. The longer you maintain the quality of the potato, the better you can pick the right trading moment and achieve maximum profit. Mechanical cooling is an excellent method for potato storage with the longest shelf life and without quality loss.
With mechanical cooling, the refrigeration is specifically designed for your product. We have already built many mechanical cooling installations at several clients, for, among other things, the storage of carrots, onions, and potatoes. We can maintain product quality for a longer period of time than with traditional ventilation systems, thanks to the specific design of the installation and the highly accurate tailoring of both temperature and humidity. The management of the installation controls the system in such a way that it automatically adapts to the characteristics of your product. Environmental factors no longer have any influence because the environment is entirely isolated.
With mechanical cooling, you always ensure a stable temperature and humidity while storing potatoes, which benefits the quality of your product. The potato sprouts slower and retains its size and weight. Minimal aging of the potato also occurs, because fewer sugars are formed in the potato. As a result, less post-processing is required and this leads to lower energy consumption and therefore a cleaner production process.
The manner in which potatoes are stored and grown, are becoming increasingly important. More often, French fries producers and fast-food chains are being asked to explain how their suppliers have organized their production processes and how they use raw materials. Therefore, potato growers must produce in a more sustainable and energy-efficient way, for example by replacing synthetic refrigerants with natural refrigerants. These resources are environmentally friendly and often more energy-efficient, without compromising the cooling capacity.
Our client, Borgmann, opted for a sustainable cooling installation based on natural refrigerants. Henk Tebben, Project Manager at ENGIE Refrigeration says: “Cooling independently from the outside air results in considerably less dehydration of the product. This is what we have seen at our client Borgmann. Dehydration of 10% is common, but with our innovation, we achieved less than 3% dehydration. This resulted in increased weight, better product quality, and therefore higher yields.” In addition to that, Borgmann now produces in a much more energy-efficient manner.
