This thesis deals with the consideration of dough cooling systems in terms of qualitative properties, as well as energy and environmental aspects.
In a literature study, the individual systems are first compared to each other. The information generated is then used in expert interviews and questionnaires to help answer various questions. In particular, it discusses the opportunities and risks in the bakery industry for different dough cooling systems and how these are used in the bakeries.
In the further course of the work, this information is used to make general statements regarding energy consumption, carbon dioxide emissions and possible alternative courses of action.
In terms of energy consumption, it has been found that brine is the cheapest alternative, with the lowest emissions. However, as brine is not fully usable, the use of binary- or slurry-ice is recommended. Direct cooling via cryogenic gas such as CO2 is not competitive with any of the systems described in this paper.
As the "Quelleis"-system, which is an binary-/slurry-ice system, seems to be relatively unknown, it could not yet establish itself on the market, despite its great potential, also with regard to a cross-industry commitment.
