Abstract

The invention relates to a device for dispensing liquid yeast in a bakery, including: an inner panel ( 2 ) of a refrigerated chamber ( 6 ) onto which an inner circuit ( 20 ) for the flow of liquid yeast is pre-mounted, wherein said inner circuit is intended to be connected to a liquid yeast vessel ( 4 ) and includes a pumping unit ( 21 ); an outer panel ( 1 ) of a refrigerated chamber ( 6 ) onto which a liquid yeast metering device ( 16 ) and a metering table ( 10 ) are pre-mounted, wherein said metering table is intended to receive a vessel ( 3 ) to be filled with an amount of liquid yeast metered by said liquid yeast metering device ( 16 ). Said inner panel ( 2 ) and said outer panel ( 1 ) are structured such as to be attached sandwiched onto the wall ( 5 ) of a refrigerated chamber ( 6 ) for containing said vessel ( 4 ). Said liquid yeast metering device ( 16 ) is intended to be connected, through a wall ( 5 ) of the refrigerated chamber ( 6 ), to said inner circuit ( 20 ).
