[0021] Preferably, the distillation barrel 1 is made of stainless steel, the barrel wall of the distillation barrel 1 is provided with a hot water chamber 6, and the hot water chamber 6 is wrapped with a heat preservation layer 10. The wine liquid is complex and it is difficult to accurately control the temperature of the wine liquid by the heater 2.
