Problems solved by technology

However, astragalus polysaccharides are very easy to absorb moisture in the air. When the product package is opened, astragalus polysaccharides will absorb moisture and become damp within 5 minutes, and will agglomerate within 15 minutes. The difficulties seriously affect the use and promotion of astragalus polysaccharides

Embodiment 1

[0013] Soak 100kg of Radix Astragali plus 6 times of water for 1 hour, heat to 100°C, extract twice for 1 hour, heat and concentrate to a relative density of 1.134-1.136. 30kg of the astragalus polysaccharide extract obtained, plus 55kg of starch and 15kg of dextrin, are placed in a one-step granulator for granulation and coating. The concentration of the coating agent acrylic resin solution is 5%. The process conditions are as follows: air intake: 4 gear, inlet air temperature 40-50°C, outlet air temperature 35-40°C, atomization pressure 1.5bar, nozzle diameter 1mm, spray speed 3-4ml / min.

Embodiment 2

[0015] Soak 100kg of Radix Astragali plus 6 times of water for 1 hour, heat to 100°C, extract twice for 1 hour, heat and concentrate to a relative density of 1.134-1.136. 30kg of the astragalus polysaccharide extract obtained, plus 60kg of starch and 10kg of dextrin, are placed in a one-step granulator for granulation and coating. The concentration of the coating agent acrylic resin solution is 5%. The process conditions are as follows: air intake: 4 gear, inlet air temperature 40-50°C, outlet air temperature 35-40°C, atomization pressure 1.5bar, nozzle diameter 1mm, spray speed 3-4ml / min.

Embodiment 3

[0017] Soak 100kg of Radix Astragali plus 6 times of water for 1 hour, heat to 100°C, extract twice for 1 hour, heat and concentrate to a relative density of 1.134-1.136. 28kg of the astragalus polysaccharide extract obtained, plus 52kg of starch and 20kg of dextrin, are placed in a one-step granulator for granulation and coating. The concentration of the coating agent acrylic resin solution is 6%. The process conditions are as follows: air intake: 4 gear, inlet air temperature 40-50°C, outlet air temperature 35-40°C, atomization pressure 1.5bar, nozzle diameter 1mm, spray speed 3-4ml / min.

Abstract

The invention relates to a method for producing astragalus polysaccharide particles. The method comprises the following processing steps: preparation of an astragalus polysaccharide extract: using astragalus mongholicus as a raw material and adding water of which the weight is 6 times of that of the astragalus mongholicus to soak the astragalus mongholicus for 1 hour; heating and extracting the astragalus mongholicus twice at the temperature of 100 DEG C, and then concentrating an obtained extractive to a relative density of 1.134-1.136 at the concentration temperature of 100 DEG C to obtain the astragalus polysaccharide extract; pelletization and coating of astragalus polysaccharides: putting the astragalus polysaccharide extract, starch and dextrin in a one-step pelletizer to carry out bottom-spray and pelletization and also carrying out coating while palletizing. The invention has the advantage that: after pelletization, the astragalus polysaccharides are packed by a macromolecularsubstance so as to ensure that the astragalus polysaccharides are isolated from external environment and not easy to absorb moisture and cake and have good flowability and more uniformity while beingmixed with feeds; the adoption of a water-soluble coating material does not influence the application of the astragalus polysaccharides with water; and the method also improves the availability of theastragalus polysaccharides, prolongs the retention period of the astragalus polysaccharide and is beneficial to the use and the popularization of the astragalus polysaccharides.

Description

technical field [0001] The invention relates to a production method of astragalus polysaccharide granules. The invention belongs to the technical field of feed and feed additives. Background technique: [0002] Astragalus is the root of leguminous plants Astragalus membranaceus and Astragalus mongolica. Astragalus membranaceus is warm and sweet in nature, enters the lungs and returns to the spleen meridian. It has the functions of invigorating qi and raising yang, strengthening the surface and antiperspirant, detoxifying and promoting muscle growth, diuresis and reducing swelling, etc. It is one of the most commonly used qi invigorating drugs in clinical practice. [0003] Astragalus polysaccharide is one of the main active ingredients of Astragalus, which can be used as an immune booster or regulator, and has anti-virus, immune-enhancing, anti-stress, and anti-oxidation effects. However, astragalus polysaccharides are very easy to absorb moisture in the air. When the prod...
