Problems solved by technology
Among them, most of the enterprises use electromagnetic vibrating vortex powder removal sieves. There will always be a little fine powder on the surface of the medicine particles treated by this powder removal sieve, which will bring greater damage to the subsequent coating and / or packaging processes. quality risk
In addition, this kind of powder removal sieve also has disadvantages such as high working noise, high energy consumption, high failure rate, complicated cleaning and installation, and low comprehensive powder removal efficiency.

The invention discloses a method and device for removing fine powder on the surfaces of tablets. The method for removing the fine powder on the surfaces of the tablets includes the steps of enabling the tablets to fall from the high positions, enabling the tablets falling from the high positions to be in contact with an elastic element or a component with the elastic element, and enabling kinetic energy generated by tablet falling to have the mutual effect with the elastic element to shake off the fine powder attached to the surfaces of the tablets. By means of the method for removing the fine powder, the kinetic energy generated by the fact that the tablets fall from the high positions is effected with the elastic element to shake off the fine powder attached to the surfaces of the tablets, the aim of fine powder removing is achieved without additionally adding any other power source, and large noise, large energy waste and the like cannot be generated accordingly.
Description
technical field [0001] The invention relates to the technical field of pharmacy, in particular to a method and a device for removing fine powder attached to the surface of tablet pharmaceutical preparations. Background technique [0002] In the pharmaceutical industry, during the compression process of tablet production, there will be some fine powders on the surface. These fine powders not only affect the appearance of pharmaceutical preparations and cause pollution, but also affect the weight inspection of the preparations and the subsequent packaging of the preparations. big impact. For example, when the aluminum-plastic blister packaging machine packs medicine granules, due to the large amount of fine powder attached to the outer surface of the medicine granules, the bonding effect between the aluminum foil and the plastic is greatly reduced, which cannot meet the requirements of pharmaceutical packaging, resulting in poor quality of medicines. Pass or scrap. [0003] ...
