Embodiment Construction

[0019] Wash and drain 100 kg of oily beans with water, add 200 kg of 0.2% sulfurous acid solution, soak at 50°C for 48 hours, remove and drain, and reserve about 230 kg of soaking water for sugar extraction. Then add 500 kg of clear water to soak at room temperature for 30 minutes, and then refine through a refiner with the function of separating pulp and slag to obtain about 350 kg of primary slurry, and add 300 kg of clear water to the residue for secondary refining, and the separation of pulp and slag to obtain a secondary slurry of about 210 kg, about 560 kg of combined primary and secondary slurry is used to extract starch and oil, and about 240 kg of wet residue is used to extract sugar.

[0020] After refining, the slurry is passed through a 200-mesh sieve, the oversize and wet residue are combined for sugar extraction, and the undersize is centrifuged with a centrifuge at a speed of 3500r / min for 10 minutes to obtain the upper layer of oil-water mixture and the lower la...

Abstract

The invention relates to agricultural product deep processing, and relates to a production technology for continuously extracting starch, oil and sugar from cyperus esculentus. The method comprises the steps that: raw materials are crushed and grinded into a first slurry; water with a volume two times than that of the residue from the previous step is added to the residue, and a second grinding step is carried out; an obtained slurry is separated such that a second slurry is separated from the residue; the first slurry and the second slurry are mixed for extracting starch and oil, and the residue is used for extracting sugar; oil is extracted through an aqueous enzymatic method; the obtained oil is layered through centrifuging and is enzyme-killed, such that upper layer oil and cyperus esculentus crude oil are obtained; sugar is extracted; extracted sugar is in a form of transparent light yellow syrup, and serves as a raw slurry for the preparations of various sugars.

Description

technical field [0001] The invention belongs to the category of deep processing of agricultural products, and in particular relates to a production process for continuously extracting starch, oil and sugar from oily bean. Background technique [0002] The underground tuber (dried fruit) of Youshadou has an oil content of 25-30%, a sugar content of 15-20%, a protein content of 10-15%, a starch content of 20-25%, and a vitamin content of 8-14mg / 100g. The comprehensive nutritional content exceeds that of wheat and corn . It is a new type of multi-purpose oil crop with great development prospects. Planting oily bean has a good market prospect and application value. [0003] Yousha beans have a high yield and high economic value. Yousha beans can be used for oil extraction, sugar refining, wine making, and milling. Distiller's grains, powder dregs, and cakes are still high-quality feed. [0004] After hydroxymethylation of oily bean starch, both hot paste and cold paste have g...
