Embodiment 1

[0016] Produce dry powder with the concentrated liquid of alcoholic fermentation liquid, the concentrated liquid of alcoholic fermented liquid accounts for 92% of raw material gross weight, rice bran accounts for 8% of gross weight, every ton of raw material adds 4 kilograms of yeast strains, ferments at normal temperature for 30 hours, obtains finished product. Its composition is: organic matter 45.4%, moisture 10%, potassium oxide 8.7%, pH 5.7.

Embodiment 2

[0018] Produce dry powder with the concentrated liquid of alcoholic fermentation liquid, the concentrated liquid of alcoholic fermented liquid accounts for 87% of raw material gross weight, and rice bran accounts for 13% of gross weight, adds 3 kilograms of yeast strains per ton of raw material, ferments at normal temperature for 36 hours, obtains Finished product: organic matter 49.3%, moisture 9%, potassium oxide 7.3%, pH 6.1.

Embodiment 3

[0020] Produce dry powder with the concentrated liquid of alcoholic fermentation liquid, the concentrated liquid of alcoholic fermentation liquid accounts for 83% of the total weight of raw materials, rice bran accounts for 17% of the total, add 5 kg of yeast strains per ton of raw materials, and ferment at room temperature for 25 hours to obtain finished products : Organic matter 49.3%, moisture 8.7%, potassium oxide 6.2%, pH 6.7.

Abstract

The invention discloses a method for making dry powder of concentrated molasses alcohol fermentation liquid and is characterized in that the method comprises the following steps of: mixing a concentrate of molasses alcohol fermentation liquid having a concentration of 50 to 60 Baume degree with rice bran, wherein the concentrate of molasses alcohol fermentation liquid accounts for 83% to 92% the weight of the mixture and the rich bran accounts for the balance; inoculating yeast 3 to 5 kg per ton of raw materials and allowing fermentation at room temperature for 24 to 36 hours; and heating to dry and grinding to obtain dry powder. The method utilizes the molasses alcohol fermentation liquid which causes serious environmental pollution in cane sugar industry, recycles the molasses alcohol fermentation liquid as complete organic liquid fertilizer for sugarcanes, makes dry powder of molasses alcohol fermentation liquid, not only eliminates inconvenience of use, transport and storage of liquid fertilizers, but also achieves the purposes of turning waste into treasures, improving soil fertility and increasing sugar yield, realizes zero discharge of pollutants and clean production, prevents environmental pollution, and promotes sustainable development of sugar industry.

Description

technical field [0001] The invention relates to a method for preparing dry powder from concentrated molasses alcohol fermentation liquid. Background technique [0002] Guangxi is the largest sugar industry base in my country, and its cane sugar production accounts for about 70% of the country's total. The cane sugar industry is an important economic pillar of Guangxi, and the use of molasses fermentation to produce alcohol, lysine, yeast, etc. is an important way for the comprehensive utilization of sugarcane by-products. However, due to the technical and cost issues of using molasses fermentation liquid to produce more off-line products have not been well resolved, most of the molasses fermentation liquid is discharged as waste liquid, causing serious environmental pollution. In fact, the ingredients in the molasses fermentation liquid are mainly various nutrients absorbed by sugarcane from the soil and various organic substances synthesized in the body, which are the nitr...
