Abstract
A system (1) and a method for cooling freshly baked bread under sub-pressure, which system includes: a sub-pressure chamber (2) which is adapted for receiving freshly baked bread for the cooling thereof; a sub-pressure source (3), such as a vacuum pump, which is connected to the sub-pressure chamber (2) for exhausting fluid from the sub-pressure chamber (2) and creating a sub-pressure inside it; a condenser (4) for cooling steam exhausted from the sub-pressure chamber and separate condensed water (19) from it. The system also includes a heating tank (5) with a first heat exchanger (6) in which the heat generated by the condenser (4) is used for heating water.
Claims11
A method of cooling freshly baked bread under sub-pressure, the method comprising:
- placing freshly baked bread in a sub-pressure chamber for the cooling thereof;
- exhausting fluid from the sub-pressure chamber by a sub-pressure source and creating a sub-pressure inside the sub-pressure chamber;
- condensing steam exhausted from the sub-pressure chamber by a condenser and separating condensed water from the sub-pressure chamber;
- and
- heating water in a heating tank in which the heat generated by the condenser is used for the heating.
The method according to claim further comprising heating the condensed water that has been separated from the fluid exhausted from the sub-pressure chamber with the heat generated by the condenser.
