Production method of special plant feed additive for aquaculture

Abstract

The invention provides a production method of a plant feed additive for aquaculture. The production method comprises the following steps: drying fresh leaves of eucommia bark, grinding the leaves, adding deionized water to extract the ground leaves for 4-6 hours, carrying out suction filtration on the extracting solution and pumping the extracting solution into a storage tank, re-adding deionized water for secondary extraction, mixing the extracting solutions, carrying out refined filtration on the extracting solution mixture and carrying out vacuum concentration until the Baume degree is 35-38 degrees Be, thus preparing a eucommia bark natural extract capsule core; preparing a capsule wall material into a capsule wall material solution; mixing the capsule core with the capsule wall material solution in a weight ratio of 1 to 1 to prepare a suspension and stirring the suspension uniformly until the Baume degree is 20-25 degrees Be; pumping the obtained mixed liquid into a spray drying tower by a high-pressure homogeneous pump, carrying out airflow atomization and instantaneously drying the atomized grains into microcapsules at high temperature being 170-180 DEG C. The production method has the beneficial effects that the produced feed additive has enhancement of flowability, is easy to mix uniformly, has strong buoyancy and is beneficial to being eaten by fish; the functional component use degree is high after aquatic animals are fed with the feed additive.

Description

technical field [0001] The invention relates to a production method of an aquaculture plant feed additive, in particular to the production of microcapsules based on Eucommia leaf extract, and the product is specially used as an additive for aquatic premixed feed or compound feed. Background technique [0002] Eucommia ulmoides is a unique Chinese medicinal material in my country. The plant tissue contains more than 80 kinds of natural active substances such as lignin, phenylpropanoids, iridoids, flavonoids, polysaccharides, oils, amino acids, etc. The ingredients, especially the content of chlorogenic acid in Eucommia leaves are as high as 3%, which have pharmacological effects such as antibacterial, anti-inflammatory, detoxification, choleretic, blood pressure lowering, increasing white blood cells, significantly increasing gastrointestinal motility and promoting gastric juice secretion. [0003] In addition to being used in traditional Chinese medicine to treat diseases, Eu...

Problems solved by technology

[0004] Eucommia ulmoides is a plant-extracted, refined, and spray-dried powder of Eucommia ulmoides leaves. When used in feed processing and animal breeding, the dosage form is relatively simple, especially when the bait is put into water in aquaculture, functional components such as chlorogenic acid are easily soluble in water. , reducing the effect of using
