Embodiment 1

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

[0027] 2) Low-temperature freezing: spread out the Dendrobium officinale section obtained in step (1) for freezing, and the freezing temperature is -5°C.

[0028] 3) Low-temperature pulverization: the Dendrobium officinale section obtained in step (2) is pulverized at a low temperature of -5°C, and sieved to obtain 40-100 mesh coarse powder.

[0029] 4) Low-temperature vacuum microwave drying: The crude Dendrobium officinale powder obtained in step (3) is dried by low-temperature vacuum microwave, the power is turned on, and the microwave power is adjusted: 1kw, total microwave drying time, 2h, drying temperature: -5°C; vacuum degree: 0.04Pa. In the microwave drying process, a microwave treatment method of 30s interval and 30s heating can be adopted (that is, the heating is stopped for 30s every 30s, and then the heating is continued for 30...

Embodiment 2

[0034] 1) Pretreatment: Take fresh Dendrobium officinale medicinal materials, remove impurities, wash with water, and cut into 2~4cm sections;

[0035] 2) Low temperature freezing: spread the Dendrobium officinale section obtained in step (1) for freezing, and the freezing temperature is -40°C.

[0036] 3) Low-temperature pulverization: the Dendrobium officinale section obtained in step (2) is pulverized at a low temperature of -40°C, and sieved to obtain coarse powder of 40-100 mesh.

[0037] 4) Low-temperature vacuum microwave drying: The crude Dendrobium officinale powder obtained in step (3) is dried by low-temperature vacuum microwave, the power is turned on, and the microwave power is adjusted: 15kw, total microwave drying time, 0.5h, drying temperature: -40℃; vacuum degree : 0.09Pa. During the microwave drying process, a microwave treatment method with an interval of 30s and heating for 30s can be adopted (that is, the heating is stopped for 30s every 30s, and then the heatin...

Embodiment 3

[0042] 1) Pretreatment: Take fresh Dendrobium officinale medicinal materials, remove impurities, wash with water, and cut into 2~4cm sections;

[0043] 2) Low-temperature freezing: spread out the Dendrobium officinale section obtained in step (1) for freezing, and the freezing temperature is -20°C.

[0044] 3) Low-temperature pulverization: The Dendrobium officinale section obtained in step (2) is pulverized at a low temperature of -20°C and sieved to obtain coarse powder of 40-100 mesh.

[0045] 4) Low-temperature vacuum microwave drying: The crude Dendrobium officinale powder obtained in step (3) is dried by low-temperature vacuum microwave, the power is turned on, and the microwave power is adjusted: 6kw, total microwave drying time: 1h, drying temperature: -20°C; vacuum degree: 0.06Pa. During the microwave drying process, a microwave treatment method of 30s interval and 30s heating can be adopted (that is, the heating is stopped for 30s every 30s, and then the heating is continu...

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 ultrafine pulverization processing of traditional Chinese medicine, and particularly 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 ultra-fine powder, and has been widely used in all walks of life. In recent years, with the rapid development of modern industrial technology and medical science, as well as the mutual penetration of disciplines, the application of ultrafine grinding technology in the processing of traditional Chinese medicine has attracted more and more attention. Chinese herbal medicines and their decoction pieces are experiencing a huge Change. In order to meet the needs of modern Chinese medicine, a new type of Chinese medicine decoction pieces developed on the basis of superfine pulverization technology-Chi...
