Method for producing alcohol raw material utilizing sugar plant mud waste sugar

Abstract

This patent provides a method to produce alcohol using discarded sugar materials from sugar refinery's mud. In the sugarcane refinery, the sugar juice is filtered in the press filter as normal technology, stop filtering when the filter mud is spreaded all over the press filter. use sugar condensed water to wet the mud until saturation, then continue to filter the mud for 1-6 min. Collect the filtered sweet water, send to the alcohol factory to replace the molasses diluted water of alcohol fermentation process, clean up the mud in the press filter, then filter sugar juice over again. Using the sweet water instead of molasses's diluted water during the alcohol fermentation, water consumption can be saved, the burden of sludge treatment can be alleviated, and the alcohol productivity can be increased 0.5-1%, all of which contributed to increase enterprise's efficiency.

Description

technical field [0001] The present invention relates to a new method of alcohol production. In particular, the use of waste sugar in the filter mud of the sugar industry to produce alcohol. Background technique [0002] The sugar press filter mud still contains a small amount of sugar, which has no economic value in sugar production, but the sugar left in the carbonation filter mud will bring greater difficulties to the treatment of the filter mud. Poor treatment of carbonic acid filter sludge will bring certain pollution to the environment. It has been a subject of research for many years to extract the sugar from the filter mud of the carbonic acid process of sugar production to the maximum extent with economic value.

Problems solved by technology

2. The carbonic acid filter mud contains too much CaCO 3 and Ca(OH) 2 , it is difficult to produce fertilizer

[0003] From the above public documents, we can know that, except for document 4, which proposes that the sugar in the filter sludge of the sulfitation process sugar factory can be used to produce alcohol, there is no article mentioning that the sugar in the filter sludge of the carbonic acid process can be used
