Embodiment 1

[0021] A preparation method of drum-dried kudzu root powder, comprising the following steps:

[0022] Take 3kg of fresh kudzu root and wash it thoroughly, crush and make a pulp. The kudzu pulp uses a vibrating screen to separate the crude fibers, and the slurry uses a cyclone desander to remove solid inorganic particles. The technological conditions are that the aperture of the vibrating screen is 30 mesh, and the working pressure of the desander is 0.5Mpa.

[0023] After desanding, the slurry is subjected to three-stage fine grinding with a wet ultrafine grinding machine. The process conditions are that the speed of the ultrafine grinder is 14000 rpm / min, and the fineness of the feed liquid after grinding is 6 μm.

[0024] After ultra-fine grinding, the feed liquid is dried by a drum dryer. The process conditions are that the drum material film thickness is 2mm, the drum speed is 6rpm / min, and the drum outer wall temperature is 55°C. Finally, the whole pueraria pueraria pow...

Embodiment 2

[0027] A preparation method of drum-dried kudzu root powder, comprising the following steps:

[0028] Take 5 kg of fresh kudzu root and wash it thoroughly, crush and make a pulp. The kudzu pulp uses a vibrating sieve to separate the crude fibers, and the slurry uses a cyclone desander to remove solid inorganic particles. The technological conditions are that the aperture of the vibrating screen is 50 mesh, and the working pressure of the desander is 0.6Mpa.

[0029] After desanding, the slurry is subjected to three-stage fine grinding with a wet ultrafine grinding machine. The technological conditions are that the speed of the ultrafine grinder is 15000 rpm / min, and the fineness of the feed liquid after grinding is 5 μm.

[0030] After ultra-fine grinding, the feed liquid is dried by a drum dryer. The process conditions are that the thickness of the drum material film is 3mm, the drum speed is 7rpm / min, and the temperature of the outer wall of the drum is 100°C. Finally, the...

Embodiment 3

[0033] A preparation method of drum-dried kudzu root powder, comprising the following steps:

[0034] (1) Thoroughly clean the surface silt of fresh kudzu root, crush and make a pulp. The kudzu pulp uses a vibrating sieve to separate coarse fibers, and the slurry uses a cyclone desander to remove solid inorganic particles. The process conditions are as follows: the aperture of the vibrating screen is 20 mesh to 60 mesh, and the working pressure of the desander is 0.10 to 0.70Mpa.

[0035] (2) After desanding, the slurry is subjected to three-stage fine grinding with a wet ultrafine grinding machine. The process conditions are that the speed of the ultrafine grinder is 10000rpm-18000rpm / min, and the fineness of the feed liquid after grinding is 5-10μm.

[0036] (3) After ultrafine grinding, the feed liquid is dried by a drum dryer, and then pulverized by a pulverizer to obtain powdered kudzu root powder. The process conditions are that the material film thickness of the drum ...

Abstract

The invention provides a preparation method of drum-dried kudzuvine root whole powder, and belongs to the field of deep processing of agricultural and sideline products. The method comprises the following steps: crushing and pulping cleaned fresh kudzuvine roots, sequentially separating crude fibers by using a vibrating screen, removing solid inorganic particles by using a cyclone desander, carrying out whole-process wet grinding, drying by using a roller dryer, and crushing by using a crusher to obtain a kudzuvine root whole powder finished product. The kudzuvine root whole powder is preparedby adopting a whole-process wet process, a large number of effective nutritional ingredients in kudzuvine roots are effectively reserved, and the utilization rate of kudzuvine root raw materials is increased; compared with a dry process, the content of puerarin in the prepared kudzuvine root whole powder is remarkably increased, and the kudzuvine root whole powder is particularly suitable for requirements of people suffering from diabetes, hyperglycemia and hyperlipidemia and middle-aged and elderly consumers. The kudzuvine root whole powder is prepared by completely adopting a wet process, so that the loss of nutritional ingredients in the processing process is avoided, and the nutritional ingredients in the kudzuvine root are more comprehensively reserved; the method is an innovative upgrade of a traditional dry-method kudzuvine root whole powder processing technology.

Description

technical field [0001] The invention relates to the technical field of food and health products, and at the same time relates to the deep processing technology of agricultural and sideline products, in particular to a method for preparing drum-dried kudzu root powder. Background technique [0002] Pueraria lobata is the root of Pueraria mirifica or Pueraria vine, which is a plant of the genus Pueraria in the leguminous family. It has been included in the list of "medicine and food with the same origin" by the National Health and Medical Commission, and is known as "Southern kudzu and northern ginseng". "Compendium of Materia Medica" records: "Kudzu, sweet, pungent, flat, non-toxic, cures mainly: diabetes, body fever, vomiting, various disadvantages, yin qi, and detoxification." Modern research shows that kudzu root is rich in starch, dietary fiber, essential amino acids, trace elements, etc., and its nutritional value is extremely high; it is also rich in isoflavones, which ...
