Problems solved by technology

Although China's ethanol processing industry has developed rapidly in recent years, the presence of aflatoxin in corn is still the biggest obstacle for China's self-produced DDGS to be used as feed raw materials
It is unavoidable that various toxins in DDGS feed exceed the standard due to the production of fuel ethanol from corn that has been stored for a short period or extended period

Embodiment 1

[0040] In this embodiment, the method for co-producing ethanol, fructose and various by-products with sweet sorghum stalks and corn comprises the following process steps:

[0041] (1) Pretreatment of sweet sorghum stalks: fresh sweet sorghum stalks are crushed and squeezed with special sweet sorghum juicing equipment to obtain sorghum juice with a sugar content of 20.2% and sorghum juice with a water content of 57.5% and a sugar content of 5.1%. Sorghum slag.

[0042] (2) Corn pretreatment: Grinding dry corn granules containing 63.5% starch to obtain corn flour for later use.

[0043] (3) Preparation of fructose syrup and fructose: Sweet sorghum juice is used to prepare fructose syrup and fructose. The fructose includes crystalline fructose and medicinal fructose, and the by-product fructose syrup can be directly used as a product.

[0044] The preparation of high fructose syrup includes the following processes: 1. After the sweet sorghum juice is coarsely filtered by a centr...

Embodiment 2

[0051] In this embodiment, the method for co-producing ethanol, fructose and various by-products with sweet sorghum stalks and corn comprises the following process steps:

[0052] (1) Sweet sorghum stalk pretreatment: Fresh sweet sorghum stalks are crushed and squeezed with special sweet sorghum juicer to obtain sorghum juice with a sugar content of 23.7% and sorghum juice with a water content of 59.6% and a sugar content of 5.4%. Sorghum slag.

[0053] (2) Corn pretreatment: Grinding dry corn granules containing 65.4% starch to obtain corn flour for later use.

[0054] (3) Preparation of fructose syrup and fructose: sweet sorghum juice is used to prepare fructose syrup and fructose, the fructose includes crystalline fructose and medicinal fructose, and the by-product fructose syrup can be directly used as a product;

[0055] The preparation of high fructose syrup includes the following processes: 1. After the sweet sorghum juice is coarsely filtered by a centrifuge, a flat c...

Abstract

The invention discloses a method for coproduction of alcohol, fructose and multiple side products by using sweet sorghum stalks and corn. The method comprises the following process steps: (1) pretreatment of the sweet sorghum stalks; (2) pretreatment of the corn; (3) preparation of fructose syrup and the fructose; (4) preparation of fuel alcohol; (5) preparation of DDGS (Distillers Dried Grains with Solubles) and liquefied natural gas; (6) preparation of silage feed; (7) recovery of carbon dioxide. The method disclosed by the invention has the beneficial effects that by utilization of the sweet sorghum stalks and the corn as raw materials, all products can be ensured to have more stable raw-material sources, coproduction of multiple products such as the alcohol, the fructose, the liquefiednatural gas and the feed can be realized, the energy consumption of final products can be reduced, the comprehensive cost of the raw materials is low, the utilization is high, and the method is energy-saving and environmentally friendly and plays an important role in fully utilizing and transformation of saline-alkali wastelands in the northeast region of China.

Description

technical field [0001] The invention relates to the technical field of comprehensive industrial deep processing of sweet sorghum stalks and corn, in particular to a method for co-producing ethanol, fructose and various by-products with sweet sorghum stalks and corn. Background technique [0002] sweet sorghum ( Sorghum dochna ) is a variant of grain sorghum belonging to the Gramineae family. It originated in Africa. It was spread to China through India during the Wei and Jin Dynasties. It has been planted for a long time as a feed and sugar crop. It is known as "northern sugarcane". Sweet sorghum has a wide range of uses. It not only produces grain, but also produces sugar and syrup. It can also be used to make wine, alcohol and monosodium glutamate. The fiber can also be used to make paper. It is not only a food crop, but also a cash crop, forage crop, and energy crop. Sweet sorghum is a high-energy crop, and its photosynthetic conversion rate is as high as 18% to 28%. Sw...
