Before the product is fried, it should be properly dried. This will raise the quality of the end result of the frying process, which results in a more crispier endproduct.
For the drying process, recovered heat may be used, for example heat released from the frying process. This technology combines high quality with sustainability.
Retro gradation is a process that takes place within the potato itself when it is cooled down after boiling or blanching. It changes the structure of the cells inside the potato.
A retro gradation machine will cool down the potato over a longer period of time, which will partly remove the water from the starch, while reinforcing the cell wall. This is an important process in the hash brown line.
