In a subsequent step 70, the cast masses are then dried in the drying room 53 for 48 hours to reduce their moisture content.
After this, in a subsequent step 71, cast food substitutes formed from the dried masses are created in the powder mogul casting machine 54, which are either gum-like or foam-like.
The food substitutes undergo cleaning in the cleaning unit 56. The cleaned food substitutes then undergo stream-treatment in the steam-treatment unit 57.
