Embodiment 1

[0046] (1) Take out the decocted ginkgo leaf residue extracted from the ginkgo leaf extract, drain the water, and then use a dryer to dry at 100-300°C (7-12 hours), and then use a vibrating ultrafine pulverizer to pulverize into 500-mesh superfine powder to obtain ginkgo biloba residue powder;

[0047] (2) Collect the fresh waste liquid from the Ginkgo biloba decocting extract in the processing of Ginkgo biloba extract, which flows out after the macroporous adsorption resin column absorbs Ginkgo flavonoids, put it into a vacuum rotary evaporator, and put it into a vacuum rotary evaporator at a temperature of 65°C and a vacuum degree of -0.1 Concentrate under the condition of MPa until the specific gravity of the waste liquid is 1.35 (measured at 40°C) to obtain the concentrated liquid;

[0048] (3) Weigh 255 kg of ginkgo leaf residue powder obtained in step (1) and 85 kg of concentrated solution obtained in step (2) respectively, place them in a tank mixer and stir fully, and ...

Embodiment 2

[0055] (1) Take out the decocted ginkgo leaf residue extracted from the ginkgo leaf extract, drain the water, then dry it in a hot air drying oven at 100-300°C (7-12 hours), and then pulverize it with a vibrating ultrafine pulverizer into 800-mesh superfine powder to obtain ginkgo leaf residue powder;

[0056] (2) Collect the fresh waste liquid from the Ginkgo biloba decocting extract in the processing of the Ginkgo biloba extract, which is absorbed by the macroporous resin column to absorb the ginkgo flavonoids, and put it into a tube-type evaporating concentrator. Concentrate under the condition of -0.085MPa until the waste liquid has a specific gravity of 1.4 (measured at 40°C) to obtain a concentrated liquid;

[0057] (3) Weigh 204 kg of ginkgo leaf residue powder obtained in step (1) and 102 kg of concentrated solution obtained in step (2) respectively, place them in a tank mixer and stir fully, and add an appropriate amount of water during the stirring to make the materi...

Embodiment 3

[0064] (1) Take out the ginkgo leaf residue after decocting the extracted ginkgo leaf extract, drain the water, and then use a dryer to dry at 100-300°C (7-12 hours), and then use a universal grinder to grind it into 100 Purpose fine powder, get ginkgo biloba residue powder;

[0065] (2) Collect the fresh waste liquid from the Ginkgo biloba extract in the processing of Ginkgo biloba extract after passing through the macroporous adsorption resin column to absorb the ginkgo flavonoids, put it into the concentration tank, and put it into the concentration tank under the conditions of temperature at 75°C and vacuum degree of -0.09MPa Concentrate under low pressure until the specific gravity of the waste liquid is 1.4 (measured at 40°C) to obtain a concentrated solution;

Abstract

The invention in particular discloses a method for preparing a single-cell protein feed additive by utilizing ginkgo leaf processing wastes. The method comprises the following steps: processing ginkgo leaf to extract the ginkgo leaf extract (GBE), drying the ginkgo leaf residues, grinding into ultra-fine powder, concentrating the outflow liquid waste subjected to macroporous resin adsorption in the ginkgo leaf extract preparation process into the concentrated solution, mixing at the weight ratio of the ginkgo leaf residue powder to the concentrated solution being (2-3) to 1, adding 15 weight percent of compound microbial fermentation agent for performing fermentation cultivation, carrying out Maillard reaction, drying at low temperature, pressing into granules, and packaging, thereby obtaining the single-cell protein feed additive product. According to the scheme in the invention, the technical gap of the domestic single-cell protein feed additive prepared by utilizing the ginkgo leaf processing wastes is filled, novel methods, process and technical routes are provided for recycling the waste residues and liquid waste in the ginkgo leaf processing waste processing production, and the feasibility is provided for industrialized operation.
