Method for comprehensively processing konjak by wet method

Abstract

The invention relates to a method for comprehensively processing konjak by a wet method. The invention relates to the agricultural and sideline products processing technical field, and is characterized in that waste alcohol generated by processing konjak fine flour through the wet method enables standing and separating, the obtained solid object is wet ash powder; a part of the separated clarification waste alcohol is returned to a konjak fine flour processing link, another part of the separated clarification waste alcohol is used for extracting alkaloid in konjak residues, a leaching liquor enables pressure reduction and concentration, new thick alcohol enables alcohol precipitation, the separated solid object is returned to a residues alkaloid extraction operation, the liquid is concentrated to an extract to obtain crude alkaloid; the wet ash powder and the extracted residues enable pressure reduction and desolvation, and are dried to obtain dry ash powder and dry residues. The method for comprehensively processing konjak by the wet method can produce the konjak ash powder capable of being as a material for processing feed and food with the characteristics of low alkaloid content and no stench flavor, the konjak crude alkaloid and konjak residues powder (soil moisture retention material) which is harmless to plants, the alcohol consumption is little, the environmental pollution is less, the konjak utilization rate is more than 95%, and the relative processing cost is low.

Description

1. Technical field [0001] Technical field of agricultural by-product processing, specifically, the present invention relates to a wet comprehensive processing method of konjac. 2. Background technology [0002] At present, domestic deep processing of konjac is mainly concentrated on konjac fine powder (ie extracting glucomannan). The processing of konjac powder mainly includes dry method and wet method, among which the konjac powder processed by wet method is of good quality and is very popular among users. But there is following defective in the wet process that domestic adopts at present: 1. only produce a kind of product of konjac fine powder, other components of konjac are all discharged as waste, both have reduced konjac utilization rate, polluted environment again. ② Alcohol consumption is large. 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 borat...

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
