Attachment Nr. 1 is a fermentation chamber for the production area. The salami goes in there for a couple of days. You can regulate temperature, humidity and cooling. The first 2 - 5 days are crucial in fermented sausage production. Attachment Nr. 2 is a maturing chamber which can be placed in the retail area of the store. Here you can ripen the salami. This machine is available in a version for salami maturing or for dry-aging beef. This would definitely enhance the retail store and create a good shopping experience for customers.
