Embodiment 1

[0052] Example 1: Extraction of raw sugar juice with sugarcane and extraction of residual sugar from its residue.

[0053] ① Weigh 100kg of cane stems and stalks without cane roots, leaves and cane sheaths, and take a small sample for measurement; sugar content is 16.7%, reducing sugar is 0.85%, crude fiber is 6.3%, ingredients are 0.8%, organic non-sugar content is 1%, moisture content is 75.3% %

[0054] ②Put the sugarcane into a fast-rotating stalk cutting and granulating machine (UE series stalk cutting and granulating machine produced by Xiamen Wuhua Tianbao Biological Engineering Co., Ltd.). 0.2-3mm, 0.2-1.5mm thick, thin strips and fine needles or small flakes of hard fibers that have been separated from the pulp core; at the same time, the sugar-filled pulp core composed of countless vascular bundles without fibers has been cut into about Small particles with a diameter of about 1-3mm. Due to the fast cutting speed and the extremely brittle sugarcane, the mixture of ...

Embodiment 2

[0063] Example 2: Extraction of raw sugar juice with sweet sorghum stalks and extraction of residual sugar from its residue

[0064] ① Weigh 100 kg of sweet sorghum stalks without sweet sorghum roots, leaves and small spike heads, and take a small sample to measure the sugar content of 17.2%, reducing sugar 1.1%, crude fiber 7.4%, ash content 0.92%, organic non-sugar content 1.2% %, moisture 73.8%.

[0065] ②Put the sweet sorghum stalks into a fast-rotating stalk cutting and granulating machine (UE series cutting and granulating machine produced by Xiamen Wuhua Tianbao Biological Engineering Co., Ltd.), the hard and dense outer skin of the sweet sorghum stalks is quickly cut to grow 10-45mm in width. 0.2-1.5mm has been detached from the pituitary thin strips and needles or small flake-like fibers, and the fiber-free pulp core composed of countless vascular bundles is also cut into small particles with a diameter of about 1-3mm very quickly mixture with a volume of 0.61m 3 , ...

Abstract

The invention relates to a method for centrifugally extracting sugar juice from cane and sweet sorghum stalks; the method comprises the steps that (1) the sugar cane and sweet sorghum stalks are cut and broken continuously and fast, and the hard and dense herbaceous lignocellulose husk is cut into strand, needle or thin slice shaped objects which is 5 to 60 mm long , 0.2 to 3 mm wide, and 0.2 to 1.5 mm thick, meanwhile, the fibreless core which is abundant with sugar juice and consists of numberless tiny vascular bundles is cut into tiny particles with a diameter from 0.5 to 3.5mm; (2) the cutstripy fiber and granular core particles mixture are put into solid-liquid separation centrifuge to be decentralized for 5 to 8 minutes, and more than 80 percent of the raw juice sugar solution can be obtained. The invention method is characterized by short technical process, less application equipments, small investment, less water consumption, fast sugar juice extracting and high juice yield and is a novel method with convenience, high efficiency and energy saving; the method of the invention is also applicable for extracting sugar juice from raw material like sugarbeet, sweet corn stalks,etc.

Description

technical field [0001] The present invention relates to a method for extracting sugar juice from sugarcane and sweet sorghum stalks, in particular to extracting from the mixture of thin needle-like outer skins and small granular pith cores obtained by cutting and crushing sugarcane and sweet sorghum stalks by centrifugal method The method of a large amount of raw sugar juice. Background technique [0002] As we all know, the extraction of sugar juice from sugar cane and sweet sorghum stalks in the world usually uses the "pressing method" and "exfiltration method". Explain its problems and shortcomings: [0003] 1. "Squeeze method": put the light stalk sugarcane from the cane leaves and sheaths into operation on the chain conveyor, first cut into small sections of about 30 cm by the cutter, and then enter 1 to 2 tearing machines, the sugarcane The segments are torn into strips or fragments, and then leveled by the leveling mechanism, iron and impurities are removed by the i...
