Red wine has gradually entered ordinary families because of its health-preserving effect, but there are also some problems. If the red wine is not drunk in time, it will deteriorate, resulting in waste. The design of this product aims to extend the shelf life of red wine after opening. After verification, the best storage temperature of red wine is 5~15 ℃, so the product uses semiconductor refrigeration to control the storage temperature, and the automatic cleaning function and nitrogen pressure to take wine can effectively reduce the pollution of the external environment for red wine.
