Device and method using centrifugation for extracting a liquid and heat loss compensating means

摘要

A method for producing a liquid extract from food ingredients in a beverage producing device that has a brewing unit driven in centrifugation. The method includes providing food ingredients in the brewing unit, supplying heated liquid in the brewing unit, centrifuging the brewing unit thereby generating centrifugal forces forcing liquid to flow through the food ingredients, and dispensing the liquid, along with an operation for compensating the thermal losses of the liquid extract in the brewing unit or the collecting unit.

主权项

1. A beverage production device for preparing a liquid extract by interaction between a liquid and food ingredients to form the liquid extract by centrifugation of the liquid passing through the ingredients, comprising:
a centrifugal brewing unit for receiving the food ingredients, a collecting unit for collecting the liquid extract centrifuged outside the centrifugal brewing unit, with the collecting unit having an impact wall forming a surface of impact for the centrifuged liquid extract and a receiving cavity which is a member that is separate from and is located below the impact wall for receiving the liquid extract impacted on the impact wall, driving means connected to the centrifugal brewing unit for driving the centrifugal brewing unit in rotation, liquid supply means being connected to the centrifugal brewing unit to supply liquid in the centrifugal brewing unit, a heater for heating the liquid supplied in the centrifugal brewing unit to a brewing temperature, and additional heating means arranged to heat the liquid extract; wherein the additional heating means is separated from the heater and includes a heating element that is (a) in contact with the receiving cavity or (b) is a thermoblock located below the impact wall and below but in thermal association with the receiving cavity, wherein the heating element of (a) or (b) provides heat to the extract in the receiving cavity after its formation and collection without heating the impact wall, so that the liquid extract leaving the centrifugal brewing unit has a temperature that is near the temperature of the liquid supplied to the centrifugal brewing unit.
