Embodiment 1

[0052] see figure 2 , embodiment 1 is that the technology of producing fuel ethanol Elaeagnus erae polysaccharides as raw material is as follows:

[0053] Add 30kg of the date powder from which impurities and fruit stones have been removed, and add process water with a pH of 3.5 to 5.0 to make a slurry to obtain date pulp.

[0054] The jujube pulp is separated from the solid and liquid, and the clear mash is sent directly to the fermentation tank; after the separation, the solid is composted or dried to produce feed;

[0055] The clear mash directly enters the fermentation tank, inserts yeast, adds antibacterial agent, and stirs and ferments at 30-34°C for 36-40 hours; in the tank, it is fermented by yeast to generate alcohol, and sterile air is introduced during the fermentation process to keep the yeast Vitality, when the concentration of residual sugar in the mash is lower than 0.5%, the fermentation is terminated to obtain fermented mature mash;

[0056] The mature mash...

Embodiment 2

[0066] see image 3 , embodiment 2 is that the technology of producing fuel ethanol Elaeagnus erae polysaccharides as raw material is as follows:

[0067] Add 175kg of the date powder from which impurities and fruit stones have been removed, and add process water with a pH of 3.5 to 5.0 to make a pulp to obtain date pulp. The mass concentration of the date pulp is controlled to be 15 to 30%, and the sugar content is about 15%;

[0068] Jujube pulp has been subjected to three solid-liquid separation processes such as beating, washing, and separation (such as Figure 5 shown), the clear liquid after each separation is collected, the clear liquid of the second solid-liquid separation is used for beating of the first solid-liquid separation, and the clear liquid of the third solid-liquid separation is used for the beating of the second solid-liquid separation , the clear liquid collected by the first solid-liquid separation is subjected to multi-effect evaporation and concentrati...

Embodiment 3

[0079] see Figure 4 , Figure 5 , embodiment 3 is that the technology of producing fuel ethanol Elaeagnus erae polysaccharides as raw material is as follows:

[0080] Add 220kg of the date powder from which impurities and fruit stones have been removed, to process water with a pH of 3.5 to 5.0 containing nutrient salts, and beat to obtain jujube pulp. The mass concentration of the jujube pulp is controlled to be 20 to 35%;

[0081] The jujube pulp is preheated to 30-60°C by the heat exchanger through the steam waste heat from the distillation and dehydration section, and pectinase is added in a proportion of 0.05-0.1%, and kept for 1-2 hours, and then undergoes multiple grinding, washing, and separation. Collect the supernatant liquid, carry out multi-effect evaporation and concentration, and concentrate the supernatant to a sugar content of 16-24%; the concentrated mash is directly sent to the fermentation tank; the separated solids are composted or dried to produce feed; ...

Abstract

The invention discloses a method for producing fuel ethanol and elaeagnus angustifolia polysaccharide by using elaeagnus angustifolia fruits as raw materials. The method comprises the steps of elaeagnus angustifolia pretreatment, pulping, solid-liquid separation, fermentation, ethanol distillation, dehydration and elaeagnus angustifolia polysaccharide extraction. According to the method, the elaeagnus angustifolia fruits are used as raw materials to produce the ethanol through fermentation. The method is simple; the sugar alcohol conversion efficiency basically keeps consistent with that of fermentation by using starchy substances such as corn as raw materials; and a byproduct of the elaeagnus angustifolia polysaccharide can be used as a medical raw material, so that the processing value of the elaeagnus angustifolia is greatly increased, and the benefits of enterprises are increased.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of sandy dates, in particular to a process for producing fuel ethanol and polysaccharides from sandy dates. Background technique [0002] Elaeagnus angustifolia L., alias: Yinliu Hudaozi (Northeast Woody Plant Illustrated), Guixiang Liu (Henan), Yinliu (Liaoning), etc. This tree species grows in semi-arid, arid, semi-desert, and desert areas. It is distributed in the northwest desert, semi-desert area, North China, Shandong, and northeast regions of China. Elsewhere is also one of the few tree species that can survive on the Gobi Desert. First, it is known as the "treasure tree" of deserts and saline-alkali lands. [0003] Elaeagnus radix leaves contain 4% of protein, 2.4% of crude fat and 15.7% of sugar, and are high-quality feed. The pulp powder of sand date contains 6.76-7.94% of crude protein, 1.34% of crude fat, 43-59% of sugar, and 3%-11% of polysaccharide, which can be used for no...
