Embodiment

[0027] The preparation method of the present invention is as follows:

[0028] (1) Crush Cordyceps sinensis into a powder with a particle size of 1-150 μm, control the water content to 3-7%, and control the tabletting temperature to -10-5°C;

[0029] (2) The micro-powder of Cordyceps sinensis is made into large plates by dry granulation and tabletting;

[0030] (3) Crush the large plate until it can pass through a 60-80 mesh sieve, and then perform tableting by dry granulation and tabletting again to obtain the finished product.

[0031] Wherein, the concrete process condition of a kind of preferred scheme is:

[0032] 1. Raw materials: Cordyceps superfine powder with a particle size of D90=25-45μm and a moisture content of about 7%.

[0033] 2. The speed of the tablet press is 15 / h, the tablet pressing temperature is set at 2°C, the pre-compression pressure is 8kN, the main pressure is 8kN, and pressed into large tablets; after crushing, the pre-compression pressure is 8kN,...

Abstract

The invention discloses a cordyceps sinensis pure powder tablet and a preparation method thereof, which solve the problems that in the conventional tabletting process, effective constituents of the cordyceps sinensis are damaged or reduced, and the production cost is high. According to the invention, the cordyceps sinensis micro powder of which the water content is 3-7% and the particle diameter is 1-150 microns is adopted, and the tabletting operation is performed by adopting dry granulation during tabletting, wherein the tabletting temperature is -10-5 DEG C, so that the tablet is prepared. According to the invention, the process of dry granulation re-tabletting is adopted to realize the preparation of the tablet under the conditions of low temperature, low pressure and low moisture; through the adoption of the process, the problems of large pressure stress and high temperature during tabletting can be avoided, and meanwhile, the defect that the effective constituents of the cordyceps sinensis are damaged or reduced due to the thermosensitive reaction can be overcome; moreover, the tablet prepared by the method has the advantages that the appearance is attractive, the spongy surface rate and splinter rate are low, the hardness, disintegration and friability of the tablet satisfy the quality requirements of the tablet.

Description

technical field [0001] The invention belongs to the fields of health food and medicine, and in particular relates to a pure powder tablet of Cordyceps sinensis and a preparation method thereof. Background technique [0002] Usually, those skilled in the art granulate and tablet the whole powder by dry method, then crush it into granules, and then compress it into tablets, and there are usually problems. During the dry granulation process, if the roller pressure is too high, the pressed dry granules will be too hard. If the dry granules are too hard, the compressibility will be lost when the tablet is pressed. Application and Research, Electromechanical Information, No. 17, 2011, No. 299, No. 4, P43-44, Chapter 1.2). If the extrusion heat generated by extrusion on the surface of the pressing wheel cannot be effectively cooled to prevent the material from sticking and sticking to the wheel when heated, the yield will also be greatly reduced (Equipment Application and Research...
