Embodiment 1

[0020] 1. Select the tail ginseng processed by the drying method according to the requirements, cut into thin slices, and set aside;

[0021] 2. Extraction. Weigh above-mentioned flake 100kg and carry out water extraction. Add 1000kg of water for the first extraction, control the temperature at about 70°C, extract for 3 hours, and then filter to obtain 800kg of the first extract and medicinal residues; then perform the second extraction, add 800L of water, keep the temperature at 78°C, and extract for 4 Hour, filter, obtain extract 730kg, merge twice extract, obtain 1530kg extract.

[0022] 3. Filtration and clarification. The 1530kg extract that merges in the B step is filtered with a ceramic membrane of 0.22 microns, and the soluble solids obtained are 3.5% clarified tail ginseng extract 1430kg;

[0023] 4. Concentrate. Concentrate 1430kg of the extract obtained in step C with a nanofiltration membrane, and control the temperature below 45°C until the soluble solids are ...

Embodiment 2

[0027] 1. Select the tail ginseng that has been sun-dried, cut into thin slices, and set aside;

[0028] 2. Extraction. Take by weighing 200kg of the above-mentioned flakes and carry out water extraction. Add 4000L of water for the first extraction, control the temperature at about 60°C, extract for 4 hours, and then filter to obtain 3700kg of the first extract and dregs; then perform the second extraction, add 1200kg of water, keep the temperature at 75°C, and extract 2 Hour, filter, obtain extract 1100kg, merge twice extract, obtain 4800kg extract.

[0029] 3. Filtration and clarification. The 4800kg extract that merges in the B step is filtered with a microfiltration membrane to obtain 2.5% soluble solids of the clarified tail ginseng extract 4700kg;

[0030] 4. Concentrate. Concentrate 4700kg of the extract obtained in step C with a nanofiltration membrane, and control the temperature below 40°C until the soluble solid content is 8.5%; then use a centrifugal thin-film ...

Embodiment 3

[0034] 1. Select qualified tail ginseng, cut into thin slices, and set aside;

[0035] 2. Extraction. Take by weighing 500kg of the above-mentioned flakes and carry out water extraction. Add 3000kg of water for the first extraction, control the temperature below 80°C, extract for 2 hours, and then filter to obtain 2300kg of the first extract and dregs; then perform the second extraction, add 5200kg of water, keep the temperature at 70°C, and extract 4 hour, filtered to obtain 5100kg of extract, combined twice of extract to obtain 7400kg of extract.

[0036] 3. Filtration and clarification. The 7400kg extract that merges in the B step is filtered with a ceramic microfiltration membrane to obtain a soluble solid content of 3.7% clarified tail ginseng extract 7200kg;

[0037] 4. Concentrate. Concentrate 8000 kg of the extract obtained in step C with a nanofiltration membrane, and control the temperature at about 25°C until the soluble solid content reaches 9.0%; The product ...

Abstract

The invention aims to provide a polygonatum particle and a preparation method thereof. The method is to treat polygonatum, and obtain a crystal solid particle product by adoption of the technology of extraction, filtration, primary concentration through a nanofiltration membrane, continuous concentration through a centrifugal membrane evaporator, belt-type low temperature continuous drying, crushing, packaging and the like. The product has the advantages of low cost, novel technology and good quality, reserves most part of active substances of the polygonatum, and can be subjected to industrialized large-scale production.

Description

technical field [0001] The invention relates to a plant product and a preparation method thereof, in particular to a ginseng granule product and a preparation method thereof. Background technique [0002] Tail ginseng, also known as Polygonatum odoratum, is used as medicine with rhizomes. The rhizome is sweet and slightly bitter, and has the effects of nourishing yin and moistening dryness, promoting body fluid and quenching thirst. It is suitable for the treatment of diseases such as lung and stomach yin injury, dry-heat cough, dry throat and thirst, and internal heat and thirst. It can also be used as a high-grade nourishing food and delicacy and drinks. The traditional processing methods are sun-dried and steamed, and the tail ginseng is dried, and then made into medicinal raw materials or eaten. Due to the low efficiency of the drying method and the steaming method, the product quality is unstable and inconvenient to use; the steaming method will also cause some biolog...
