Description

technical field [0001] The invention relates to a supercritical substance preparation technology, more specifically, to a multifunctional supercritical particle preparation system. Background technique [0002] The so-called supercritical state refers to a special state of matter. When a certain substance is above the critical temperature and critical pressure, the properties of the gas phase and liquid phase of the substance will tend to be similar, and finally a homogenous phase (Homogenous) will be achieved. The state at this time is called supercritical state, and this special fluid is called supercritical state. It is a supercritical fluid (Supercritical Fluid, SF). Supercritical fluids are compressible like gases and have fluidity like liquids, and their densities are generally between 0.1 and 1.0 g·ml -1 between. Due to its liquid-like dissolving ability, supercritical fluid can be defined as a heavy gas with controllable dissolving ability, or a state of matter in...

Problems solved by technology

However, most of the currently widely used supercritical systems have a single function and can only realize one of the above-mentioned functions, and very few have two functions. working status

Therefore, in order to be able to realize the multi-functional supercritical preparation function, it is necessary to repurchase the corresponding supercritical preparation system, but the supercritical device is generally expensive, and the cost required is very high, which is difficult for customers to bear.
