Medical evaporator construction

October 29, 2020

Evaporation (or concentration) refers to a process in which a solution containing a non-volatile solute and a volatile solvent is concentrated by evaporation, which is obtained by vaporizing a part of a solvent in a solution by heating. Evaporation process is widely used in pharmaceutical production. For example, in traditional Chinese medicine, the extract is concentrated by evaporation to obtain a concentrate or a flow extract, and as in the production of antibiotics, it is used for fermentation filtrate, resin eluent and various extractions. Concentration of the liquid. Since the products produced by the pharmaceutical industry are usually biologically active substances or temperature-sensitive substances, this is a problem that is of particular concern when evaporative concentration operations are applied in pharmaceutical production.
Evaporation equipment is generally called an evaporator. Its structure and variety are numerous, and its development history is long. The form of its evaporator construction has also been gradually improved. Firstly, the jacket heating type was replaced by the horizontal tube heating type, and then the vertical tube heating type was improved, and the latter was further improved in extensive use. In order to avoid the influence of the static pressure of the solution, a liquid film evaporator was created, correspondingly Increased evaporation intensity. From the operation mode, it can be divided into single-effect evaporation, multi-effect evaporation and direct contact evaporation. According to the fluid circulation method, it can be divided into non-circulating evaporation, natural circulation evaporation, forced circulation evaporation, wiped film evaporation and centrifugal thin film evaporation.
Oxygen Cylinder Filling System

With PSA principles, ETR Oxygen Cylinder Filling system can produce 93%Â±3% purity oxygen gas from compressed air directly. ETR oxygen cylinder filling system is consisted of Atlas screw air compressor, refrigerated air dryer, compressed air filter, air buffer tank, ETR Oxygen Plant, oxygen buffer tank, oxygen booster, cylinder filling station and HMI control cabinet.

Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%Â±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure. With an oxygen booster, the oxygen pressure can be to 150bar and fill in cylinders.
