Triple-Stage Stainless Steel Molecular Distillation

1. Overview of molecular distillation

Wiped film vacuum distillation

 

is a special liquid separation equipment, which is different from traditional distillation such as rotary evaporator and reactors,

 

stainless steel short path distillation

 

has its unique separation principle, it relies on the different average free path of molecular movement rather than the different boiling point.

Short path wiped film distillation kit

 

has its special advantages which with high distillation efficiency and low temperature physical distillation property.

technology is widely used in distillation, purification, solvent removing, decoloration, and deodorization of many substances, especially the heat-sensitive substance.

2. Features of molecular distillation
(1). The operating temperature of the short path molecular distillation kit is far below the boiling point of the material, and the residence time of the material is really short, which is beneficial to separate materials with the high boiling point, heat sensitive and easy oxidized.
(2). The stainless steel short path distillation can effectively remove substances in liquids such as organic solvents, odors, etc, which is a very effective method for liquid desolventizing after solvent extraction.
(3). The vacuum degree of the wiped film vacuum distillation can reach below 0.1Pa ensures the material not to be oxidized easily during distillation.
(4). The triple-stage stainless steel molecular distillation can form a liquid film less than 0.5mm, which make sure that distillation with high efficiency of heat transfer.
(5). Stainless steel short path distillation with a high degree of separation can be used to separate by conventional substances that are not easily be separated.
(6). Using short path molecular distillation kit there is no boiling or bubbling phenomenon.
(7). The wiped film vacuum distillation is a physical separation method, toxic-free harmless, pollution-free and no residue, which confirms to obtain pure and safe products.
(8). The surface of the stainless steel short path distillation was contacting with materials is made of 316L stainless steel, and the exterior surfaces of the stainless steel short path distillation are made of 304 stainless steel. Which ensures the overall thermal expansion performance and thermal insulation performance of the stainless steel wiped film molecular distillation are really good.
3. Why triple-stage stainless steel molecular distillation is needed?

Stainless steel short path distillation is a distillation method operated in a high vacuum state. This method of separating liquid mixtures by using the different free path of the molecular movement of each component in the liquid material, this wiped film vacuum distillation is widely used in food, medicine, fine chemical, and other industries applications.

However, single-stage short path molecular distillation kit also has certain defects. Because single-stage stainless steel short path distillation equipment has only one heating surface and one condensation surface, for liquid materials composed by multiple mixtures entering to the wiped film vacuum distillation, there is only once distillation in the single-stage short path molecular distillation kit, which can remove most of the lightweight molecular fractions in multiple mixed liquids, and a small portion of the lightweight molecular fractions are still present in the multiple mixed liquids, due to the mixed liquid its own characteristics or the thinness of the liquid film can not be distilled sufficiently in the single-stage stainless steel short path distillation.

If there are multiple substances need to be distilled in multiple mixed liquids by single-stage short path molecular distillation kit, then the single-stage wiped film vacuum distillation must be used again and again by adding the previous distillation product to the single-stage stainless steel short path distillation equipment and reset the distillation temperature every time.

In this way not only has complicated operation and high cost, but also the product after previous distill by the wiped film vacuum distillation equipment cannot guarantee the quality and purity, due to the influence of temperature, liquid film thickness, distillation time and other factors. Therefore, the production of a multi-stage short path molecular distillation kit is very meaningful. Then the triple-stage stainless steel molecular distillation not only can get the different components from the mixed liquids at one time but also the distillation quality and purity can be improved, which can largely avoid repeated operations, labor loss and material loss.
