锥形罐啤酒发酵温度的调节与控制

Adjustment of and Controls on the Fermentation Temperature of Beer in Tapered Shaped Tank

锥形罐啤酒发酵温度的调节与控制关键是对控制工艺方法的选取,发酵周期长短对温度的影响控制;控制温度调节对啤酒风味的影响;控制好主发酵期的温度变化;双乙酰还原期温度的变化;降温阶段的温度的调节与控制;冷却贮存阶段温度的调节控制应使罐体内温度一致,一般从5～7℃降至0～-1℃,速度为0.1℃/h。（孙悟）

The key points to adjustment of and controls on the fermentation temperature of beer in tapered shaped tank were as fol-lows: selection of proper control techniques; controls on the effects of the length of fermentation on temperature; controls on the ef-fects of temperature adjustment on beer flavor; controls on temperature changes during chief fermentation period and biacetyl reduction period; temperature controls and adjustment in temperature dropping periods, generally, temperature dropped from 5~7 ℃to 0^-1℃ with the dropping rate 0.1 ℃/h; and temperature adjustment during cooling phase and storage.(Tran. by YUE Yang)
