Embodiment 1

[0017] 1) Chopping the collected fresh water hyacinth, blanching and killing it in an aqueous solution with a mass percentage concentration of ethoxyquin of 1% and a temperature of 100° C. for 5 minutes;

[0018] 2) in the sodium chloride solution that mass percent concentration is 1%, add ethoxyquin and propionic acid, make the mass percent concentration of antioxidant be 1% and the mass percent concentration 3% of preservative, will be scalded with hot water The water hyacinth after bleaching and killing green is put into it, cooled, infiltrated and dehydrated for 10 hours; then homogenized with a high-pressure homogenizer for 10 minutes to make pulp;

[0019] 3) Filter the filter press obtained in step 2), and dry the filter cake with a belt dryer until the water content is less than 15%, measure and pack to obtain dry aquatic plant powder, and return the filtrate to step 2) for recycling.

Embodiment 2

[0021] 1) Chopping the collected fresh Smilax, blanching and fixing in an aqueous solution with a concentration of 5% di-tert-butylhydroxytoluene and a temperature of 45° C. for 10 minutes;

[0022] 2) in the sodium acetate solution that mass percent concentration concentration is 20%, add di-tert-butyl hydroxytoluene and sorbic acid, make antioxidant mass percent concentration be 5% and preservative mass percent concentration be 0.001%, will pass hot water Put the water hyacinth after blanching and greening into it, cool, infiltrate and dehydrate for 10 hours; then use a high-shear emulsifier to homogenize for 2 minutes to make pulp;

[0023] 3) Filter the filter press obtained in step 2), and dry the filter cake with a tunnel dryer until the water content is less than 10%. After measuring and packaging, the dry powder of Smilax chinensis is obtained, and the filtrate is returned to step 2) for recycling.

Embodiment 3

[0025] 1) Chopping the collected fresh duckweed, blanching and finishing for 9 minutes in an aqueous solution with a sodium bisulfite concentration of 2% and a temperature of 55°C;

[0026] 2) Add sodium bisulfite and sodium diacetate to the copper chloride aqueous solution whose mass percentage concentration concentration is 10%, so that the antioxidant mass percentage concentration is 4% and the preservative mass percentage concentration is 2%. Put the water lotus after blanching and killing into it, cool, infiltrate and dehydrate for 5 hours; then use a high-pressure homogenizer to homogenize for 5 minutes to make pulp;

[0027] 3) Filter or centrifuge the obtained product in step 2), dry the filter cake with a drum dryer until the water content is less than 10%, measure and pack it to obtain dry duckweed powder, and return the filtrate to step 2) for recycling.

Abstract

An aquatic plant dry powder and a preparation method. The preparation method comprises following steps: (1) cutting collected fresh aquatic plant and blanching the fresh aquatic plant in an aqueous solution in which an anti-oxidant is 1-5% in mass percentage concentration and of which a temperature is 45-100 DEG C for 5-10 min for de-enzyme of the aquatic plant; (2) adding the anti-oxidant to an inorganic salt solution or an organic salt solution with a mass percentage concentration being 1-20% to prepare a hyperosmotic solution of which the mass percentage concentration of the anti-oxidant is 1-5% and the mass percentage concentration of a preservative is 1-3%, pouring the blanched fresh aquatic plant into the hyperosmotic solution, cooling the blanched fresh aquatic plant and performing osmotic dehydration for 5-10 hours, and preparing a slurry material through a high-pressure homogenization machine or a high-shear emulsifying machine; and (3) filtering or centrifugally separating the slurry material to obtain a filter cake, and drying, weighing and packaging the filter cake to obtain the aquatic plant dry powder, wherein a filtrate is recycled for the step (2).

Description

technical field [0001] The invention relates to the field of resource utilization of aquatic plants, in particular to a dry powder of aquatic plants and a preparation method thereof. Background technique [0002] Utilizing aquatic plants such as water hyacinth, water floating lotus and duckweed to control the eutrophication of rivers, lakes, ponds and reservoirs is a very effective method: (1) higher aquatic plants such as water hyacinth, water floating lotus and duckweed It can quickly absorb a large amount of nutrients in the water body for its own growth. Their root exudates can inhibit or kill algae and germs, effectively inhibit the growth of harmful algae and germs, and quickly improve water quality; Aquatic plants themselves are aquatic plants with ornamental value, which add beauty to rivers and lakes and beautify the water landscape. Compared with traditional sewage treatment methods, it has the advantages of less investment and low energy consumption, and is a ver...
