Problems solved by technology

For active products (which are sensitive to temperature) that have gradually emerged in recent years, the current high-temperature coating method has the following defects: 1. High temperature is easy to destroy the activity of the product and reduce its efficacy; 2. Coating consumption 3. The coating effect is not uniform, and the coating consistency of each grain cannot be guaranteed; 4. Special granulation equipment is also needed before coating; Technical issues of how active products are coated

Abstract

The invention relates to low-temperature coating equipment and a production process, and belongs to the technical field of pharmaceutical equipment. The coating equipment comprises a first forming device, a first filling device, a first quick-freezing device, a second forming device, a second filling device, a second quick-freezing device, a third filling device and a third quick-freezing device which are sequentially arranged above a packing material conveying mechanism. In the whole coating process, the active ingredient liquid can be always kept in a low-temperature state, the activity of the active ingredients sensitive to the temperature is effectively guaranteed, and the functional effect of the active ingredients is improved; a streamlined operation mode is adopted, manual interference is avoided, the efficiency is high, and the productivity is large; the productivity of a production line can be easily improved according to the productivity requirement; compared with conventional large-batch coating, the effect of single coating can be ensured; according to the invention, a final coating finished product is directly formed from a packing material, and other extra granulation equipment and the like are not needed; and the problems that in the existing coating process, the product activity is reduced, consumed time is long, and coating is not uniform are solved.

Description

technical field [0001] The invention relates to low-temperature coating equipment and a production process, belonging to the technical field of pharmaceutical equipment. Background technique [0002] In the prior art, in the field of medicine and food, in order to protect the product and improve the taste, a layer of coating is added on the surface of the product, especially for tablet products. However, most of the coatings currently use shot peening coating at high temperatures. Or dip coating technology. For active products (which are sensitive to temperature) that have gradually emerged in recent years, the current high-temperature coating method has the following defects: 1. High temperature is easy to destroy the activity of the product and reduce its efficacy; 2. Coating consumption 3. The coating effect is not uniform, and the coating consistency of each grain cannot be guaranteed; 4. Special granulation equipment is also needed before coating; The technical issue ...
