The precept behind the impingement freezing methodology is that ice crystals are fashioned on the floor of meals merchandise. These crystals can solely develop to a smaller measurement, because of the processing pace. This prevents them from getting broken throughout the freezing course of and leads to a wonderfully easy completed product.

The principle good thing about utilizing this methodology over different sorts of freezers is that it’s quicker than standard freezing strategies however produces a better high quality product too! You may also use it to create smaller batches than regular freezers, which makes it splendid for small companies that don’t want as a lot freezing completed.

Meals security
