Wet comprehensive processing method of konjak

Abstract

The invention discloses a wet comprehensive processing method of konjak. A waste alcohol suspension solution generated by all links of wet-method processing of konjak fine powder is subjected to solid-liquid separation to obtain a solid matter, namely wet ash powder; one part of clarified waste alcohol obtained by processing and separating the ash powder returns back to a konjak fine powder processing link and the other part of clarified waste alcohol is used for extracting alkaloid in konjak peel residues; an extraction solution separated by extracting is firstly subjected to decompression and evaporation and alcohol is recycled; after the alcohol is concentrated to a certain degree, strong alcohol is added into a concentrated solution to carry out alcohol precipitation and separation; a separated solid matter returns back to a peel residue alkaloid extraction procedure; separated liquid is concentrated into an extract, thus obtaining rough alkaloid; the wet ash powder and the extracted peel residues are respectively subjected to decompression for desolvation and alcohol recycling, and then are dried to obtain dry ash powder and dry peel residues; finally, the dry ash powder and the dry peel residues are ground or crushed to prepare commercially available ash powder and peel residue powder.

Description

Technical field [0001] The invention belongs to the technical field of agricultural and sideline product processing, and relates to a comprehensive wet processing method for konjac. Background technique [0002] At present, the domestic deep processing of konjac mainly concentrates on the extraction of glucomannan from konjac powder. There are two main types of konjac flour processing: dry and wet. Among them, the wet processed konjac flour has good quality and is very popular among users. However, the current domestic wet process has the following defects: ① Only one product of konjac powder is produced, and all other components of konjac are discharged as waste, which reduces the utilization rate of konjac and pollutes the environment. ②High alcohol consumption. Although there are also processing techniques that use water as the medium, they either require high operational requirements and are difficult, or use harmful chemical reagents such as borate, which reduces the safet...

AI Technical Summary

Problems solved by technology

However, the wet process currently adopted in China has the following defects: 1. only one product of konjac fine powder is produced, and other components of konjac are all discharged as waste, which not only reduces the utilization rate of konjac, but also pollutes the environment

②Large consumption of alcohol

Although there are also processing techniques using water as the medium, either the operation requirements are high and difficult, or harmful chemical reagents such as borates are used, which reduces the safety and use of the product; ③Alcohol recovery is difficult and consumes a lot of energy; ④Engineering High construction and production costs
