Process for cleaning sugar cane juice in sugar production from sugar cane

Abstract

The invention discloses a novel process for cleaning sugar cane juice in sugar production which comprises the steps of, low-temperature phosphor floating treatment, pre-decolorizing with diatomaceous earth and activated charcoal, then loading to boil the sugar. The neutral filtering mud produced in the low-temperature phosphor floating method can be directly used as fertilizer. The process can eliminate the generation of alkaline sieving mud in sugar production.

Description

technical field [0001] The invention relates to a clean process for producing sugar cane juice from sugarcane, which belongs to the category of clean production process. technical background [0002] my country's sugarcane sugar industry has long adopted traditional production methods: one is carbonic acid and the other is sulfurous acid. The quality of sugar products produced by the carbonic acid production process is good, but the process is complicated, the cost is high, and the amount of filter mud is large. For every 10,000 tons of sugarcane squeezed, 800 tons of filter mud are produced. The filter mud is strongly alkaline and cannot be used as a fertilizer. Alkaline filter mud has a high content of organic matter (about 11-13%) and cannot be directly used to burn cement. It needs to be stored for more than 5 years before burning cement, so it is necessary to build a large area of ​​storage yard. In addition, secondary pollution is generated during the storage proces...

Problems solved by technology

But this technology still has the following main problems: (1) alkaline filter mud directly burns cement, the cost is higher, and is difficult to be accepted by cement manufacturers; ; (3) The process is longer than the traditional carbonic acid process
