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.

Abstract

The invention discloses a konjac glucomannan separation method and device. The konjac glucomannan separation method comprises the following steps of: pre-treating, separating, drying and cooling and post-treating. The device comprises a rack platform, a power distribution cabinet, continuous rolling and separation equipment and an alcohol metering container, wherein the rack platform is provided with the power distribution cabinet, the continuous rolling and separation equipment and the alcohol metering container; the continuous rolling and separation equipment is connected with a power grid of the power distribution cabinet; the continuous rolling and separation equipment comprises a feeding pot, cyclone separation devices, liquid discharging pipelines, a material pumping pipeline, waste material discharging pipelines and a waste material collecting device; the feeding pot is provided with the waste material discharging pipelines; the waste material discharging pipelines are connected in series through the cyclone separation devices. According to the konjac glucomannan separation method and device disclosed by the invention, the activity is guaranteed while the content of konjac glucomannan is improved; the content of sulfur dioxide in the konjac glucomannan is reduced; after the separation, the viscosity of konjac fine powder is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of food deep processing, and in particular relates to a method for separating konjac glucomannan and a device thereof. Background technique [0002] Konjac is a perennial herb. The underground tubers are flat spherical, large, with thick petioles, cylindrical, light green, with dark purple spots, and palmate compound leaves. They grow in sparse forests and have the functions of lowering blood sugar, blood lipids, and blood pressure. Pulse, weight loss, appetizer and other functions. Konjac is a beneficial alkaline food. For people who eat too much acidic food of animal origin, eating konjac together can achieve the balance of acid and alkali in food, which is beneficial to human health. Chinese folk planting and processing konjac has a history of more than 2,000 years, but it was only eaten sporadically in the southwest region before. Since 1985, with the development of the establishment economy and the im...
