Chocolate cooling tunnels are machines used as a solution to the cooling needs of industrially produced products such as biscuits, chocolate, wafer, regret, Turkish delight. With the increase in production capacity, cooling tunnels should be used to cool the products coming out of the production lines in continuous flow without waiting. The most common area where chocolate cooling tunnels are used is the freezing of products such as cream biscuits, sandwich biscuits, wafers and cakes after the chocolate is coated or after the pattern is given in the decor unit.
