How Does Short Path Distillation Work?
In short path distillation machine, the heating time of materials is short, and the separated materials are quickly cooled and collected by the condenser after overflowing from the heating surface, so that thermal decomposition, polymerization or deterioration can be eliminated.
Short path distillation is based on molecular motion and high-vacuum evaporation:
- The material is heated and forms a thin film on the evaporation surface.
- Under high vacuum, light molecules evaporate quickly at low temperatures.
- Vapor molecules travel a very short distance directly to the condenser.
- Vapors are cooled and condensed into liquid, achieving separation.
- Heavy, high-boiling residues remain and are discharged separately.
In addition, because the distance between the heating surface and the condensation surface is very close and the resistance is very small, the pressure drop caused by gas transfer is low, so it is easier to obtain a lower evaporation pressure. As long as the free path of light molecules after overflowing from the evaporation surface is greater than the distance between the evaporation surface and the condensation surface, separation can be realized without heating to the boiling point of the separated substance, so the distillation temperature is much lower than that of conventional distillation.

Overview of evaporator types
In short-range distillation equipment, it is a key component responsible for heating the material to the evaporation temperature and separating light components from the mixture.
According to different classification criteria such as evaporation method, heating form, working pressure, efficiency, and retention time, it can be divided into multiple types.
Common types of evaporators include rising film evaporators, falling film evaporators, scraper evaporators, forced circulation evaporators, etc.
Common types and application scenarios of evaporators
Rising evaporator
Characteristics:
It enters from the bottom of the product through preheated material, rapidly evaporates in the heating tube, and forms a rising thin film. This is suitable for processing materials with low viscosity, difficulty in foaming, and low thermal sensitivity.
01
Falling evaporator
Features:
It evenly distributes the material on the outer wall of the heating tube through a film distribution device to form a thin film, which flows down along the heating tube under the action of gravity and evaporates. This has the characteristics of high heat transfer efficiency and low operating temperature.
02
Scraper evaporator
Features:
It forms a thin film of material on the heating surface through a rotating scraper, and promotes the flow and evaporation of the material through the scraping effect of the scraper. This is suitable for processing materials with high viscosity, easy crystallization and precipitation, and solid particles.
03
Forced circulation evaporator
Characteristics:
Itcirculates the material through a pump in the heating chamber, causing the material to form a thin film in the heating tube and evaporate. This has the characteristics of large processing capacity and stable operation.
04
The type of evaporator in Short path distillation equipment, as the core component of the entire distillation system, directly affects the efficiency, product quality, and production cost of the distillation process.
According to different process requirements and application scenarios, the selection of product type needs to comprehensively consider multiple factors such as material properties, production scale, operating conditions, and economic benefits.
Selection criteria for evaporator type
Material properties
(1) Viscosity
The viscosity of materials is one of the important factors affecting the selection of evaporators. For materials with low viscosity, a rising evaporator or a falling evaporator can be chosen. These can form a thinner liquid film, which is beneficial for rapid evaporation and heat transfer. For high viscosity materials, it is more suitable to choose scraper evaporators or forced circulation evaporators, which enhance the fluidity of the material through mechanical force or forced circulation to ensure the smooth progress of the process.
(2) Thermal sensitivity
For heat sensitive materials, which are prone to decomposition or deterioration at high temperatures, it types with short retention time and low operating temperature should be selected. For example, the falling evaporator, due to its thin liquid film and fast heat transfer characteristics, can achieve rapid evaporation at lower operating temperatures, reduce material heating time, and lower the risk of thermal sensitive material decomposition.
(3) Foaming property
Foaming materials are easy to form foam during evaporation, which affects efficiency and product quality. For such materials, evaporator types with large separation space can be selected, such as scraper or standard evaporator, to contain and separate foam. At the same time, it can also be considered to add appropriate defoamer in the process to reduce the production of foam.
Production scale
The production scale is also one of the important considerations when choosing the type of evaporator. For small-scale production, one can choose evaporator types that are compact in structure and easy to operate, such as rising evaporators or falling evaporators.
For large-scale production, it is necessary to consider the processing capacity and stability of the evaporator, and choose an evaporator type that can withstand high loads and continuous operation, such as a scraper evaporator or a forced circulation evaporator.
Operating conditions
The operating conditions include evaporation temperature, pressure, vacuum degree, etc. Different types of evaporators have different requirements for operating conditions. For example, it typically require operation at high vacuum levels to achieve efficient; The scraper evaporator, on the other hand, has relatively low requirements for operating temperature and can operate stably over a wide temperature range. Therefore, when choosing the type of evaporator, it is necessary to consider the specific operating conditions comprehensively.
Applications
As an important component of the food industry, the beverage industry has extremely high requirements for product quality and safety. With the increasing demand of consumers for healthy, natural, and high-quality beverages, beverage production enterprises need to continuously improve their production technology and process level to meet market demand.
Extraction of Natural Flavors
In beverage production, the extraction of natural flavors is a key step in enhancing product flavor. This device can efficiently and accurately extract volatile aroma components from plants, such as essential oils, terpenes, etc. These components play an important role in enhancing the aroma and taste of beverages. Through short-range distillation, the original flavor and nutritional components of natural spices can be maximally preserved, adding unique charm to beverage products.
Concentration and Purification of Beverages
For some beverage products that require concentration or purification, such as juice, syrup, etc., this device also has significant advantages. Under high vacuum conditions, short-range distillation can effectively remove water and other low boiling impurities, improving the concentration and purity of the product.
Meanwhile, due to the short evaporation path and low operating temperature, short-range distillation can effectively avoid the damage of thermosensitive components and the loss of nutrients, ensuring the quality and taste of the product.
Production of alcoholic beverages
This equipment is also widely used in the production process of alcoholic beverages. Through short-range distillation technology, the evaporation and condensation processes of alcohol can be precisely controlled to obtain pure alcohol products.
In addition, short-range distillation can also be used in the aging and flavor adjustment stages of alcoholic beverages. By adjusting distillation conditions and parameters, alcoholic beverages can obtain more complex and rich flavors.
Removing impurities from beverages
During the beverage production process, impurities and unpleasant flavor substances are often produced. This device can remove these impurities and unpleasant flavor substances from beverages through its efficient separation capability, improving the purity and taste of the product. Especially for high-end beverage products with extremely high requirements for impurities, the application of short-range distillation technology is indispensable.
