Embodiment 1

[0026] 1) Pretreatment: take fresh Dendrobium officinale medicinal materials, remove impurities, wash with water, and cut into 2-4cm sections;

[0027] 2) Freezing at low temperature: spread out the Dendrobium candidum segments obtained in step (1) and freeze at -5°C.

[0028] 3) Low-temperature pulverization: pulverize the Dendrobium candidum segment obtained in step (2) at a low temperature of -5°C, and sieve to obtain a coarse powder of 40-100 meshes.

[0029] 4) Low-temperature vacuum microwave drying: Dry the coarse powder of Dendrobium candidum obtained in step (3) by low-temperature vacuum microwave drying, turn on the power, adjust the microwave power: 1kw, the total time of microwave drying: 2h, drying temperature: -5°C; vacuum degree: 0.04Pa. In the microwave drying process, the microwave treatment method of heating for 30 seconds at an interval of 30 seconds can be adopted (that is, stop heating for 30 seconds every 30 seconds, continue heating for 30 seconds, stop...

Abstract

The invention discloses a method for preparing dendrobium officinale super micropowder. The method comprises the following steps: (1) pretreating, namely weighing a fresh dendrobium officinale medicinal material, removing impurities, washing with water, and cutting into pieces; (2) freezing at low temperature; (3) grinding at low temperature to obtain coarse powder of 40-100 meshes; (4) carrying out low-temperature vacuum microwave drying to obtain dendrobium officinale dried powder; (5) grinding the dried powder to be below 300 meshes at low temperature by ultrasonic flow to obtain dendrobium officinale superfine powder; (6) carrying out resonance grinding to enable grain size to be between 10-300 nanometers so as to obtain super micropowder; and (7) subpackaging and packaging to obtain a finished dendrobium officinale super micropowder. The method is performed at low temperature, the activity of dendrobium officinale effective ingredients can be effectively maintained, the average grain size of the prepared dendrobium officinale super micropowder can be 10-300 nanometers, and the dissolution and absorption of the effective ingredients of the dendrobium officinale super micropowder can be remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine ultrafine pulverization, and in particular relates to a preparation method of dendrobium officinale ultrafine powder Background technique [0002] Superfine pulverization technology is a new technology in recent years. It can process raw materials into micron or even nanometer ultrafine powder, which has been widely used in various industries. In recent years, with the rapid development of modern industrial technology and medical science and the interpenetration of disciplines, the application of ultra-fine pulverization technology in traditional Chinese medicine processing has attracted more and more attention. change. In order to meet the needs of the modernization of traditional Chinese medicine, a new type of Chinese medicine decoction piece developed on the basis of ultrafine pulverization technology - Chinese medicine superfine powder decoction piece came into being. N...
