Examples
Embodiment 1
[0038] Put 200 Kg of konjac fine powder in 28% alcohol with a volume ratio of 4 times, stir and soak for 1 hour, enter the cyclone for ladder washing and desulfurization in the forward and reverse directions, and separate through the high-pressure cyclone reverse rolling continuous separation device to obtain 180Kg konjac Glucomannan (including secondary cyclone recovery section). Konjac glucomannan is dried to a moisture content of 8% and then cooled. After screening, grading, mixing and homogenization, the finished product of konjac glucomannan is obtained. The content of glucomannan is 90% after inspection, and the activity of glucomannan ( Viscosity (mpa.s) is 36000, sulfur dioxide content g / kg is 243ppm.
Embodiment 2
[0040] Put 200 Kg of konjac fine powder in 45% alcohol with a concentration of 3 times the volume ratio, stir and soak for 3 hours, enter the cyclone for ladder washing and desulfurization in the forward and reverse directions, and separate through the high-pressure cyclone reverse rolling continuous separation device to obtain 182Kg konjac Glucomannan (including secondary cyclone recovery section). Konjac glucomannan is dried to a moisture content of 10% and then cooled. After screening, grading, mixing and homogenization, the finished product of konjac glucomannan is obtained. The content of glucomannan is 95% after inspection, and the activity of glucomannan ( Viscosity (mpa.s) is 36050, sulfur dioxide content g / kg is 251ppm.
Embodiment 3
[0042] Put 200 Kg of konjac fine powder in 20% alcohol with a volume ratio of 4 times, stir and soak for 2 hours, enter the cyclone for ladder washing and desulfurization in the forward and reverse directions, and separate through the high-pressure cyclone reverse rolling continuous separation device to obtain 177Kg konjac Glucomannan (including secondary cyclone recovery section). Konjac glucomannan is dried to a moisture content of 9% and then cooled. After screening, grading, mixing and homogenization, the finished product of konjac glucomannan is obtained. The content of glucomannan is 93% after inspection, and the activity of glucomannan ( Viscosity (mpa.s) is 36200, sulfur dioxide content g / kg is 285ppm.
