Embodiment 1

[0033] according to figure 1 The operation process is as follows:

[0034]Select commercially available golden jujubes (dried jujubes) with neat appearance, natural color, no insects, no mildew, and wash them with tap water (for example, 2-3 times) to remove the dirt on the surface of the jujubes, and dry them in the air , quickly sliced ​​by a slicer, placed in a vacuum drying oven for dehydration and drying at 10°C, put the dried jujube slices into a commercially available airflow ultrafine pulverizer for ultrafine pulverization, collect ultrafine jujube powder with a particle size of 1.5 microns, and put the ultrafine jujube powder The powder is packaged in a sealed bag.

Embodiment 2

[0036] Select commercially available Hetian jade dates (dried dates) with neat appearance, natural color, no insects, no mildew, and wash them with tap water (if it can be washed 2-3 times) to remove the dirt on the surface of the dates, and dry them in the air , quickly sliced ​​by a slicer, placed in a vacuum drying oven for dehydration and drying at 100°C, put the dried jujube slices into an airflow ultrafine pulverizer for ultrafine pulverization, collect ultrafine jujube powder with a particle size of 500 microns, and seal the ultrafine jujube powder bag package.

Embodiment 3

[0038] Select commercially available Xinzheng jujubes (dried dates) that are neat in shape, natural in color, free from moths and mildew, and cleaned with tap water (if it can be washed 2-3 times) to remove the dirt on the surface of the dates and dried in the air , quickly sliced ​​by a slicer, dehydrated and dried in a vacuum drying oven at 80°C, put the dried jujube slices into an airflow ultrafine pulverizer for ultrafine pulverization, collected ultrafine jujube powder with a particle size of 20 microns, and sealed the ultrafine jujube powder bag package.

Abstract

The invention discloses ultra-micro Chinese date powder and a preparation method thereof. The method for preparing the ultra-micro Chinese date powder comprises the steps of 1) cleaning and air-drying dried Chinese dates; 2) slicing the air-dried Chinese dates; 3) dehydrating and drying the sliced Chinese dates in vacuum under the condition of temperature of 10 to 100 DEG C; and 4) performing ultra-micro smashing on the dehydrated Chinese dates, and collecting the Chinese data powder with the particle sizes of 1.5 to 500 microns. The dispersion degree, the dissolving degree, the dissolving rate, the adsorbility, the biochemical activity and the like of the ultra-micro Chinese data powder prepared by the method are better than those of the ultra-micro Chinese data powder prepared by the conventional smashing method; and compared with the conventional smashing method, the preparation method has the advantage that the biological utilization rate and the health protection effect are greatly improved.

Description

technical field [0001] The invention relates to a jujube powder and a preparation method thereof, in particular to an ultrafine jujube powder and a preparation method thereof. Background technique [0002] Jujube has been a traditional Chinese medicine since ancient times.
