Process for making sugar by using sorgo

Abstract

The invention discloses a process for making sugar by using sorgo. The process comprises the following steps: pretreatment: tearing sorgo straws into straw filaments; squeezing: delivering the obtained sorgo straw filaments to a squeezer, extruding sorgo juice after three times of squeezing, letting the sorgo juice flow out of sieve pores on the wall of a chamber body of the squeezer and collecting the sorgo juice in a first container; filtration: delivering the obtained sorgo juice to a filter to obtain pure sorgo juice, separating the sorgo straw dregs and scraping the dregs with a first scrape blade to a second container; clearing: heating the obtained pure sorgo juice, adding lime milk to neutralize the juice, adding calcium hydroxide emulsion and acetic acid solution to stir, reacting at a constant temperature for 20-40 minutes, heating the solution, then adding a flocculation additive acrylamide, statically keeping the solution at a constant temperature, flocculating and settling to obtain clear sugar juice, and finally concentrating the sorgo juice to obtain concentrated syrup. The process has a good squeezing effect, a high juice yield, a good filtration effect, a good decolorization effect and little filtering sludge, and saves time and labor.

Description

technical field [0001] The invention belongs to the field of sugar production, in particular to a sweet sorghum sugar production process. Background technique [0002] Sweet sorghum, also known as sugar sorghum, is a variant of common grain sorghum. Sweet sorghum is a 4-carbon crop with high light efficiency. It is characterized by its stalks containing sugar juice. The stalk juice Brix is ​​generally around 17%-22%. It is known as a high-energy crop. The photosynthetic efficiency of sweet sorghum is 2-3 times that of soybean, sugar beet, wheat and other crops, so its stalk yield is also quite high, and the fresh stalk yield per hectare can reach 75-300 tons, which shows that its biological yield and sugar production are relatively high. Sugar beet and sugar cane have obvious advantages. Currently in the world such as Mexico, Italy, Australia, Israel, India, Brazil and other countries, sweet sorghum is cultivated as sugar crops. The purpose of clarifying sweet sorghum jui...

Problems solved by technology

Regarding the decolorization technology of sugar juice, sugar workers from all over the world have carried out a lot of research, and successively proposed ion exchange technology, membrane separation technology, ultra-freezing crystallization technology, biological enzyme method, inorganic-organic composite clarifier and its clarification process and other methods, but its cost is high and technical, and it has not been widely used in production in my country.
