A Guide to Short Path Distillation System

Distillation Definition

Distillation is a thermodynamic separation process that utilizes the different boiling points of each component in a mixed liquid or liquid-solid system to evaporate the low-boiling component and then condense to separate the entire component. It is a combination of two unit operations of evaporation and condensation.

Compared with other separation methods, such as extraction, filtration crystallization, etc., its advantage is that it does not need to use other solvents other than system components, thereby ensuring that no new impurities are introduced.

Short Path Distillation System

Short path distillation systems are called by various names, depending on the manufacturer and the compound being distilled.

Short-path distillation is a relatively new liquid-liquid separation technology, which can solve many problems that cannot be solved by conventional distillation technology.

The main components of short-path distillation mainly include: molecular evaporator, degassing system, feeding system, heating system, cooling vacuum system and control system.

Molecular evaporators are the core part of short-path distillation, and there are three main types: falling film, wiped film, and centrifugal.

In order to improve the separation efficiency, it is often necessary to use multiple stages in series to achieve multi-stage separation of different substances.

Short Path Distillation vs Conventional Distillation

1. Short-path distillation: separation can be carried out at any temperature, and the operating temperature is much lower than the boiling point of the material.

Conventional distillation: separation is carried out at boiling temperature.

2. Short-path distillation: free evaporation on the surface of the liquid film, low operating pressure and short heating time.

Conventional distillation: there is bubbling and boiling.

Short Path Distillation in the Cannabis Industry

Short path distillation has the ability to separate compounds. Cannabis processing manufacturers use this feature to isolate and purify the cannabinoids in cannabis. A high-purity, high-quality concentrate is obtained that can be sold individually or further processed into various products.

High-quality concentrates require high-quality equipment. The short-path distillation of Henan Lanphan Industrial Co., Ltd. is well received by customers and is in a leading position in the industry. There are 2L 5L 10L 20L to choose from.
