Abstract
The invention relates to a method for processing konjac powder with a wet method. The method comprises the following steps: sending konjac pieces or konjac dumplings into a grinding machine to be ground, and sorting through a cyclone separator and a vibrating screen to obtain below 80 meshes, 80-120 meshes and over 120 meshes of primary powder; sending each mesh of primary powder into an anti-swelling tank with the alcohol concentration being 35-45 percent to be immersed, stirred and washed; carrying out centrifugal liquid removal and vacuum drying to the washed powder, and recollecting an anti-swelling solution to obtain purified konjac powder; the weight ratio of the primary powder in the anti-swelling tank and alcohol is (1: 3.0)-(1: 4.0). The primary powder is screened and is immersed, stirred and washed under different conditions, so that the alcohol dosage of the anti-swelling solution is reduced, and the cost is reduced. A complicated operation process is not needed, and the operation is easy. The konjac powder produced by the method has low impurity content, high purity, high viscosity and good transparency, and the method is a low-consumption efficient konjac powder processing method.
Description
Technical field
The present invention relates to food processing technology field, be specifically related to a kind of method of wet processes konjaku powder.
Background technology
The core of konjaku powder processing is separation and extraction konjac glucomanna from the konjaku stem tuber, is actually the material such as the starch removed wherein, protein, fiber and obtains comparatively pure konjac glucomanna particle.
At present, extract the method for konjac glucomanna from konjaku, summarizing has two large classes: a class is dry method, and another kind of is wet method.The fine powder purity that the conventional dry working method is produced is lower, and yield is also low, and it is not high to cause product utilization to be worth.For solving the existing problem of traditional method, people develop the method with the wet processes konjaku powder, namely utilize organic solvent to make machining medium, prevent the konjac glucomanna swelling, under the machining medium condition, pulverize to grind, separate again, drying, better with the fine powder quality of this method acquisition, but its consumption edible ethanol amount is large, causes production cost high.
" a kind of working method of konjak glucomannan fine powder " (CN1314349C), the Rhizoma amorphophalli glucomannan meal to be sent in the cryogenic mill grind, obtain elementary fine powder through the cyclopneumatic separator sorting, it is to soak pressing down in the swollen tank of 30-70 that elementary fine powder is sent into ethanol concn, stir, washing, powder after the washing is ground refinement, centrifugally deviate from ashes and moisture, vacuum-drying, oven dry, reclaim pressing down swollen solution alcohol, elementary fine powder after the oven dry is sent into vibration in the low temperature oscillating grinding tool again, the whirlwind sorting obtains Rhizoma amorphophalli glucomannan purifying fine powder or micro mist.
Summary of the invention
The objective of the invention is for above-mentioned present situation, aim to provide that a kind of to press down swollen solution alcohol consumption few, cost is low, the method for the wet processes konjaku powder that the product foreign matter content is low, purity is high, viscosity is high, transparency is good.
The implementation of the object of the invention is, a kind of method of wet processes konjaku powder, taro sheet or taro angle sent in shredder grind, obtain below 80 orders through cyclopneumatic separator and vibratory screening apparatus sorting, 80-120 orders, the elementary fine powder that 120 orders are above, it is that concentration is 35-45% the fully immersion in the swollen tank that presses down that the elementary fine powder of each order is sent into ethanol concn, stir, washing, powder after the washing carries out centrifugal dewatering, vacuum-drying, to press down swollen solution collects again, obtain the purifying konjaku powder, pressing down the interior elementary fine powder of swollen tank and the weight ratio of alcohol is 1:3.0-1:4.0.
The present invention soaks elementary fine powder sub-sieve, stir, wash under different condition, makes to press down swollen solution alcohol consumption minimizing, has reduced cost; Do not need complicated operating process, processing ease.
The konjaku powder that the present invention produces, foreign matter content is low, purity is high, viscosity is high, transparency is good, is a kind of low consumption, efficient konjaku powder working method.
Embodiment
Repeatedly study discovery through the applicant, fine powder granular size and its solvent swelling state in machining medium is closely related, and the control temperature of reaction will improve the konjac glucomanna yield greatly.For reducing the consumption that uses edible ethanol in the production process, improve the fine powder quality product, the present invention obtains the different-grain diameter type with elementary fine powder sorting, under the certain temperature condition, soak, stir, wash according to different condition, powder after the washing is carried out centrifugal dewatering and vacuum-drying, to press down simultaneously swollen solution and again collect, recycle, obtain purifying konjaku powder (konjak gum).It is few to press down swollen solution alcohol consumption, and cost is low.
The present invention sends into taro sheet or taro angle in shredder and grinds, and obtains sorting through cyclopneumatic separator and vibratory screening apparatus sorting and obtains below 80 orders 80-120 orders, the elementary fine powder that 120 orders are above.
Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
1000kg taro sheet, taro angle are sent in shredder and ground, obtain elementary fine powder 674kg below 80 orders through cyclopneumatic separator and vibratory screening apparatus sorting, the elementary fine powder 193kg between 80-120 orders, the elementary fine powder 78kg that 120 orders are above.
It is 35% press down in the swollen tank that the elementary fine powder of 80 orders is sent into ethanol concn, fully soaks, stirs, washs under 30 ℃ of conditions.Elementary fine powder is 1:4.0 with pressing down swollen solvent feed ratio.Powder after the washing carries out centrifugal dewatering, and 60 ℃ of lower vacuum-dryings are carried out homogeneous to vacuum drying konjaku powder, obtains purifying konjaku powder (konjak gum) 553kg.The alcohol in the tail gas in the vacuum-drying is reclaimed actual consumption alcohol 272kg by alcohol recovery device.
It is 40% press down in the swollen tank that elementary fine powder between 80-120 orders is sent into ethanol concn, fully soaks, stirs, washs under 40 ℃ of conditions.Elementary fine powder is 1:3.5 with pressing down swollen solvent feed ratio.Powder after the washing carries out centrifugal dewatering, and 60 ℃ of lower vacuum-dryings are carried out homogeneous to vacuum drying konjaku powder, obtains purifying konjaku powder (konjak gum) 164kg.The alcohol in the tail gas in the vacuum-drying is reclaimed actual consumption alcohol 67kg by alcohol recovery device.
It is 40% press down in the swollen tank that elementary fine powder more than 120 orders is sent into ethanol concn, fully soaks, stirs, washs under 50 ℃ of conditions.Elementary fine powder is 1:3.0 with pressing down swollen solvent feed ratio.Powder after the washing carries out centrifugal dewatering, and 60 ℃ of lower vacuum-dryings are carried out homogeneous to vacuum drying konjaku powder, obtains purifying konjaku powder (konjak gum) 68kg.The alcohol in the tail gas in the vacuum-drying is reclaimed actual consumption alcohol 39kg by alcohol recovery device.
