Abstract

The invention discloses a device for aging yellow rice wine by using a deep ultraviolet LED (Light Emitting Diode) and a control method thereof. The device comprises a deep ultraviolet light source, an irradiation chamber, a wine inlet, an exhaust window, a temperature control system and a control unit, the deep ultraviolet light source is fixed to the top of the irradiation chamber, and an LED is provided with an AlN ceramic substrate and an aluminum radiator; the temperature control system monitors and adjusts the yellow wine temperature; the control unit controls on and off of the LED, irradiation time and temperature adjustment. The method comprises the steps that yellow wine to be aged is filtered and then placed in a closed container; a deep ultraviolet LED is adopted to irradiate the yellow wine, the LED emission wavelength is 255-275 nm, the irradiation intensity is 30-50 W / cm < 2 >, the irradiation distance is 10 cm, and the irradiation time is 10-30 days; the temperature is kept at 20-25 DEG C in the irradiation process; and after the irradiation is completed, standing and packaging in a dark environment. According to the method, the yellow wine can be naturally aged for 1-5 years within 10-30 days, the aging time is remarkably shortened, the storage cost is reduced, and the aging effect is stable and controllable.
