BEER SERVER

摘要

A compact, inexpensive, and low-power-consumption beer server that controls beer temperature at nearly 0° C. and prevents the beer from freezing. The beer server includes a beer tank 12, a primary cooling tank 16, and a secondary cooling tank 18. Beer in the beer tank 12 is cooled to 2 to 5° C. in the primary cooling tank 16. Thereafter, the beer is cooled to 0° C. in the secondary cooling tank 18. A control unit 50 controls agitation fins 22 so that a beer temperature T1 at an outlet of the primary cooling tank 16 is a predetermined temperature of 2 to 5° C. The secondary cooling unit 18 is composed of two heat exchangers 30a and 30b. The control unit 50 controls refrigerant supplied to heat exchangers 30a and 30b so that a beer temperature T2 at an outlet of the secondary cooling tank 18 is a predetermined temperature of nearly 0° C.

主权项

1. A beer server comprising:
a beer tank that stores beer; a primary cooling unit having a cooling tank storing cooling water, an agitator that agitates the cooling water, a beer cooling pipe disposed in the cooling water and through which the beer flows from the beer tank, and a refrigerant evaporation pipe disposed in the cooling water; a secondary cooling unit having a heat exchanging part that directly exchanges heat between the beer primarily cooled by the primary cooling unit and a refrigerant not through a heat medium so as to secondarily cool the beer; a dispensing nozzle that dispenses the beer cooled by the secondary cooling unit; a freezer that supplies a low temperature refrigerant to the refrigerant evaporation pipe of the primary cooling unit and to the secondary cooling unit; a first temperature sensor that detects a beer temperature at an outlet of the primary cooling unit; a second temperature sensor that detects a beer temperature at an outlet of the secondary cooling unit; and a control unit into which detected values of the first temperature sensor and the second temperature sensor are inputted, the control unit being configured to control an operation of the agitator to set the beer temperature at the outlet of the primary cooling unit to a predetermined value, and to control an amount of the refrigerant supplied to the second cooling unit to set the beer temperature at the outlet of the secondary cooling unit to a predetermined value.
