Preparation method for producing wet-process konjac powder by ball milling method

Abstract

The invention discloses a preparation method for producing wet-process konjac powder by a ball milling method. The preparation method comprises the following steps: sieving after coarse crushing, grinding at low temperature, grinding by a wet process, and grinding by a ball mill for a short time after drying. Through two dry and wet combined processing technologies, the particle size of the konjac powder is further reduced, the powder solubility is improved, the viscosity is reduced, the production efficiency is improved, liquid nitrogen is adopted for temperature control in the whole process, the temperature in a bin of a ball mill can be reduced, the color and the yield of the konjac powder are prevented from being influenced by heat generated by operation of the ball mill, and the production cost is reduced. And the phenomenon that the tank is exploded due to pressure rise in the ball-milling tank caused by volatilization of alcohol due to too high temperature can be prevented, effective substances in the konjac powder cannot be damaged due to high temperature under the combined action of low-temperature control and alcohol, the color is obviously improved, the color protection effect is obvious, and the product quality is improved. Meanwhile, other impurities except glucomannan in the konjac powder can be dissolved by the alcohol, so that the purity of the obtained konjac powder is higher.

Description

Technical field [0001] The present invention relates to the technical field of konjac concentrate powder preparation, specifically a ball milling method for producing wet konjac concentrate powder preparation method. Background [0002] Konjac essence powder, also known as konjac powder, or konjac glucomannan, is the main ingredient contained in konjac, the purity of konjac concentrate powder prepared in the prior art is not high, the particle size is large, the whiteness is low, for this reason we have designed a ball milling method to produce wet konjac concentrate powder preparation method. Contents of the Invention [0003] The present invention provides a ball milling method for the production of wet konjac concentrate powder preparation method can solve the problems in the above background technique. [0004] In order to achieve the above object, the present invention provides the following technical solution: a ball mill method for producing wet konjac fine powder prepara...

AI Technical Summary

Problems solved by technology

[0002] Konjac fine powder is also called konjac powder, or konjac glucomannan, which is the main component contained in konjac. The konjac fine powder prepared in the prior art has the disadvantages of low purity, large particle size and low whiteness. For this reason We have designed a preparation method for producing wet-process konjac fine powder by ball milling
