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.
