圆盘制曲机在根霉曲生产上的应用研究

Application of Disc Rhizopus Propagation Machine in the Production of Rhizopus Starter

研究了圆盘制曲机在根霉曲生产上的应用,确定了生产工艺参数：物料5000 kg,加水1600 L,加种曲150 kg,拌匀,入圆盘制曲机。入圆盘时物料品温28～31℃,静置培养14～18 h,室温维持在28～32℃之间,湿度维持在70%～90%,待菌丝结块后翻曲,继续通风培养18～20 h,品温维持在32～34℃之间,室内湿度维持在60%～80%,待品温降至30℃左右时结束培养,制得成品曲的糖化力为33.2 g/100 g,比浅盘培养根霉曲糖化力高1.4 g/100 g。

The application of disc Rhizopus propagation machine in the production of Rhizopus starter was studied. The production technical pa- rameters were determined as follows： 5000 kg raw materials mixed with 150 kg yeast with the addition of 1600 L water, then the mixed raw ma- terials temperature kept at 28～31 ℃, and then static incubation in the disc lasted for 14～ 18 h at 28～31 ℃ with the humidity of 70 %～90 % and room temperature between 28 ℃ and 32 ℃, after the caking of hypha, starter turned over and static incubation continued for 18～20 h with product temperature maintained from 32 ℃ to 34 ℃ and room humidity maintained from 60 %～80 %, as the temperature of the product dropped to 30 ℃, the incubation ended. The saccharifying power of the produced starter was 33.2g/100 g,l.4 g/100 g higher than that produced by shallow tray Rhizopus propagation machine.
