AUTOMATIC DEVICE FOR FRESH HOT BEVERAGES PREPARATION Russian patent published in 2019 - IPC A47J31/60 

FIELD: manufacturing technology; satisfaction of human vital needs.

SUBSTANCE: invention relates to a beverage preparation machine for fresh hot beverages, in particular coffee beverages, having at least one water heater, brewing device intended for supply of hot water from water heater, water pump supplying drinking water from supply pipeline for drinking water into water heater, and a flow-through flow meter for determining the volume of drinking water supplied by the water pump. Automatic device for freshly prepared hot beverages preparation has water heater (10, 20), brewing device (50) intended for receiving hot water from water heater (10, 20), water pump (11, 21) supplying drinking water from supply pipeline (30) for drinking water into water heater (10, 20), which is a flowing water heater, and flow meter (12, 22) for determining volume of drinking water supplied by water pump (11, 21). Automatic beverage preparation machine is also equipped with automatic scale removal system (40) for automatic descaling from flow-through water heater (10, 20). Automatic machine has mixing tank (41) for solution preparation of scale removal device, installation point of accumulation tank (42) for liquid concentrate of scale removal device, as well as dosing pump (43) for supply of doses of concentrate of descaling means from accumulation tank (42) to mixing tank (41), in which concentrate of descaling means is mixed with water to obtain solution of descaling means. On the suction side, water pump (11, 21) is made with possibility of a switched connection with collecting pipeline (49) of mixing tank (41) in order to supply the first distribution valve (44) in the switched position, the descaling means from mixing tank (41) to water heater (10, 20). On the pressure side, water pump (11) can be connected in a switched manner to supply water (47) of mixing tank (41) for supply of drinking water in the switched position of the second distribution valve (45) to mixing tank (41).

EFFECT: fast and accurate preparation of hot beverages, lowering frequency of maintenance and repair, as well as reliability and simplicity of operation for working personnel.
