Cooling device for liquid medicine production process

Abstract

The invention discloses a cooling device for a liquid medicine production process. The cooling device comprises a liquid medicine cooler, a cooling water cooler and a controller, wherein the liquid medicine cooler comprises a liquid medicine cooling box and a liquid medicine spiral tube fixedly mounted on the inner side of the liquid medicine cooling box; cooling water cooling fins are fixedly mounted on the outer wall of the liquid medicine cooling box; the two ends of the liquid medicine cooling box are connected with a water outlet tube and a water return tube respectively; a medicine inlettube connected with one end of the liquid medicine spiral tube is arranged in the water outlet tube; a medicine outlet tube connected with the other end of the liquid medicine spiral tube is arrangedin the water return tube; the medicine inlet tube extends out of the water outlet pipe and is connected with a medicine inlet pump; the medicine outlet tube extends out of the water return tube and is connected with a temperature sensor and a medicine outlet valve in sequence. The cooling device has the advantages of being good in cooling effect and capable of adjusting cooling temperature, facilitating follow-up processing and the like.

Description

technical field [0001] The invention relates to the field of medicine production equipment design, in particular to a cooling device in the production process of liquid medicine. Background technique [0002] In the process of liquid medicine processing, some steps need to heat the medicine for processing. For post-processing, it is necessary to cool the high-temperature liquid medicine. For a long time, the natural cooling method is adopted. It takes a long time, and standing still for a long time may cause pollution or changes in the properties of the drug in processing. Later, a device specially designed for liquid cooling in the process of liquid drug processing appeared, using a spiral pipe to cool the surface of the pipe.

[0002] In the process of liquid medicine processing, some steps need to heat the medicine for processing. For post-process processing, it is necessary to cool the high-temperature medicine liquid. For a long time, the natural cooling method is adopted. Natural cooling It takes a long time, and standing still for a long time may cause pollution or changes in the properties of the drug in processing. Later, a device specially designed for liquid cooling in the process of liquid drug processing appeared, using a spiral pipe to cool the surface of the pipe. The method of cooling the medicine liquid in the pipeline, this device greatly improves the cooling efficiency of the medicine liquid, makes the production process smoother, and the cooling effect is also very good, but the shortcomings of this device are:

[0003] 1. It cannot control the cooling temperature. For the pharmaceutical industry, the manufacture of certain medicines has high temperature requirements, so this device cannot be used when manufacturing such medicines that require temperature.

[0004] 2. The cooling of the medicine liquid is realized by circulating cooling water, but there are two ways to cool the cooling water. The first is to enlarge the cooling water tank to prolong the circulation period of the cooling water. The second is to use the cooling water Add heat dissipation device in the circulating pipeline, both of these two methods have the disadvantages of occupying too much space and high cost
