AI Technical Summary

Technical Problem

Existing methods for producing biofuel from winemaking waste face limitations due to a narrow raw material base and low consumer characteristics of the resulting pellets, such as ash deposits and high content of coloring compounds that clog filters and chimneys.

Method used

A method involving aqueous vacuum extraction of grape pomace at specific ratios and conditions to remove aromatic and coloring substances, followed by grinding, moistening, molding, and cutting into cylindrical granules, ensuring a solid fraction free of these substances, which is then formed into pellets.

Benefits of technology

The method enhances the combustion efficiency and reduces environmental impact by preventing ash deposits, improving the consumer qualities of the pellets and expanding the production methods for winemaking waste biofuel.

Abstract

FIELD: biofuel production.SUBSTANCE: invention relates to methods for producing biofuel from waste of plant origin, in particular to the production of pellets from winemaking waste and can be used in the fuel industry and for municipal and domestic needs for the utilization of biological material in the form of plant residues and waste from the winemaking industry. The method for producing pellets from grape pomace involves grinding waste from the wine industry, further forming by forcing the ground raw material through a matrix, cooling and cutting into cylindrical granules, whereas the residue, in the form of a solid fraction obtained during the process of aqueous vacuum extraction of grape pomace, is used as waste from the wine industry.EFFECT: implementation of a method for producing pellets from waste of plant origin, in particular winemaking waste, which ensures a reduction in the environmental load and an improvement in the end-user qualities of the pellets.1 cl, 1 tbl, 1 ex
