Method for preparing full-nutrient solid cane molasses

Abstract

The invention relates to a method for preparing full-nutrient solid cane molasses, namely the traditional liquid cane molasses is processed into full-nutrient solid cane molasses. The method comprises the following steps: putting liquid cane molasses without any pretreatment directly in a vacuum drying machine; removing moisture under the heating and vacuum condition; and smashing after cooling, thus powder full-nutrient solid cane molasses is obtained, wherein the drying temperature is controlled at 50-130 DEG C, and the vacuum degree is controlled within minus 0.05-minus 0.10 MPa. By adopting the method provided by the invention, the liquid cane molasses with 20-30% of water content can be converted into the full-nutrient solid cane molasses with 0.5-2.5% of water content, and the original nutrition components of the cane molasses can be preserved without influencing the using efficacy of the original cane molasses; the storage and transportation costs can be lowered; the cane molasses is convenient to use; the quality guarantee period of products is prolonged, and the application range of the products can be widened; and the method has less operation steps, has low production cost, and is easy to be industrialized.

Description

technical field [0001] The invention belongs to a method for treating by-products in the sugar production process, in particular to a method for processing traditional liquid sugarcane molasses into full-nutrition solid molasses. Background technique [0002] Sugarcane molasses is a by-product of sugarcane sugar factory, referred to as molasses, commonly known as orange juice, it is made of sugarcane as raw material, squeezed to extract juice, clarified, purified, filtered, evaporated, concentrated, crystallized, The output of the brown viscous liquid separated again is about 2.5% to 3.0% of that of the raw material sugar cane. Although the sugar cane sugar production process is processed by clarification process and evaporated and concentrated into syrup before being sent to the boiled sugar crystallization process, the purification efficiency of clarification is very limited, so there are still many organic or inorganic impurities in the syrup. These impurities affect Wit...
