REFRIGERATION EQUIPMENT

WIPO Patent Application WO/2023/151342

A1

Refrigeration equipment (1000), comprising a decanting device (300). The decanting device (300) is configured to extract wine liquid from a wine bottle (10a), and inject air into the extracted wine liquid for decantation. The decanting device (300) comprises a wine outlet mechanism (1), a first one-way valve (141), a first control valve (512), a second control valve (513), a first pump (501), a second pump (502), an air-mixing decantation cavity (40), and a wine outlet pipe (41). During wine extraction, the first pump (501) works, such that air enters the first control valve (512) and enters the wine bottle (10a) through the first pump (501), the second control valve (513) and an air flow channel (11) so as to increase the gas pressure above the wine liquid in the wine bottle (10a). Under the action of the gas pressure, the wine liquid enters a wine suction pipe (20) and flows out of the wine outlet pipe (41) through a first liquid flow channel (12) and the air-mixing decantation cavity (40). Moreover, the second pump (502) works, such that air enters the air-mixing decantation cavity (40) from the second pump (502) and is mixed with the wine liquid in the air-mixing decantation cavity (40) to achieve air-mixing decantation.
