Description
Technical Parameters
The core of the SPDU typically consists of a vacuum chamber, a heating source, a condenser, and a collection vessel. By operating under reduced pressure, the boiling point of the material is lowered, further enhancing the gentleness of the process. The heating element, often a bath filled with silicone oil or water, uniformly heats the distillation flask containing the sample.
Short-range distillation unit is a kind of separation equipment with high efficiency and environmental protection, which has a wide application prospect and significant technical advantages. With the continuous progress and innovation of technology, it will play an important role in more fields. At present, there are many brands of short-range distillation units on the market, these devices have differences in material, specifications, performance, etc., and the price range is also wide, ranging from several thousand yuan to several hundred thousand yuan. Users can choose the right equipment according to their needs and budget.

Applications
|
SPDU plays an important role in the application of cowboy refining high-carbon alcohol (also known as stearyl alcohol). Stearyl alcohol, also known as octadecyl alcohol, is a fatty alcohol with a distinct chemical structure characterized by an eighteen-carbon chain attached to a hydroxyl group (-OH). This long-chain alcohol finds its place in various industrial and consumer applications due to its unique properties. Derived primarily from natural fats and oils through a process involving hydrolysis and hydrogenation, stearyl alcohol is a waxy, white, solid substance with a mild, characteristic odor. Its molecular weight and saturated nature contribute to its stability and resistance to oxidation, making it an ideal component in formulations requiring durability and stability. In the cosmetics industry, stearyl alcohol serves as an emulsifier, stabilizer, and thickening agent. It helps create smooth, creamy textures in lotions, creams, and hair care products, enhancing their spreadability and moisturizing effects. Additionally, its emollient properties make it beneficial for soothing and protecting the skin. Furthermore, stearyl alcohol finds use in the manufacturing of surfactants, lubricants, and polymers. In surfactants, it aids in reducing surface tension, enhancing cleaning capabilities. As a lubricant, it minimizes friction and wear in mechanical parts. In polymer production, it acts as a modifier, influencing the final product's hardness, flexibility, and durability. |

Separate and purify high-carbon alcohol refined by denim. In this process, by heating and distilling the mixture, different components are separated at different temperatures, thus obtaining high-carbon alcohol products with high purity.
Impurities removal
Such as residual fatty acids, esters and other unnecessary components, in the refined high-carbon alcohol of denim. By adjusting the temperature and pressure, impurities can be selectively removed and the purity and quality of products can be improved.
Controlling product properties
Control specific properties of products, such as boiling point range, viscosity and color of target products. By adjusting the operating conditions, the product performance can be customized.
Visual Window
Visual window of SPDU refers to the window designed on short-range distillation unit for observing and monitoring distillation process.
Material selection
The visual window of distillation unit is usually made of materials with high transparency, high temperature resistance and corrosion resistance, such as high-quality glass or special alloy. This can ensure that the operator can clearly see the changes and products in the distillation process.
01
Design location
The visualization window is usually located between the evaporator and condenser of the device, so as to observe the flow and phase change of liquid in the device. Sometimes, visual windows are also set at other key locations such as collection bottles or fractionators.
02
Safety protection
In order to ensure the safety of operators, the visual window of unit usually has explosion-proof and leak-proof functions. For example, an explosion-proof device may be added to the edge of the window to prevent the window from breaking, and a sealing device may be provided to prevent gas or liquid from leaking.
03
Observation mode
The visualization window is usually designed as a transparent plate or a cylinder, which is convenient for operators to observe the distillation process through the window. Some visualization windows will also be equipped with magnifying glasses or cameras and other auxiliary devices to provide a clearer observation effect.
04
Cleaning and maintenance
The design of visual window should be considered for easy cleaning and maintenance. Some windows may be easily removed or opened for cleaning or replacement.

The working principle of the cooling system
In SPDU distillation units, the cooling system works in a relatively simple but efficient way. When the steam enters the condenser, it exchanges heat with the cooling medium, transferring heat to the cooling medium and condensing itself into a liquid. The cooling medium is constantly flowing under the action of the circulating pump, taking the heat away from the condenser and dissipating to the environment. The precise control of the temperature control system ensures that the temperature of the condenser outlet liquid is always maintained within the set range.
The cooling system characteristics and requirements
High efficiency condensation:
The cooling system should have an efficient condensing capacity that can quickly condense steam into a liquid to reduce heat loss and material degradation.
Precise temperature control:
The temperature control system should be able to achieve accurate temperature control of the cooling medium to ensure that the temperature of the condenser outlet liquid meets the product requirements.
Strong corrosion resistance:
The material and structure of the cooling system should have good corrosion resistance and be able to resist the erosion of the equipment by the chemicals in the distilled material.
Easy to maintain and operate:
The cooling system should be designed for easy disassembly and cleaning to reduce maintenance costs and time. At the same time, the operation interface should be intuitive and easy to use, convenient for operators to monitor and adjust.
Energy saving and environmental protection:
The cooling system should adopt energy-saving and environmental protection design and technology to reduce energy consumption and environmental pollution. For example, you can choose to use efficient cooling media and circulating pumps, as well as technologies such as waste heat recovery to reduce energy consumption.
Configuration of safety facilities and equipment
As an indispensable separation equipment in chemical, pharmaceutical and other fields, the operation process of short-range distillation unit involves high temperature, high pressure, flammable and explosive risk factors, therefore, well-configured safety facilities and equipment are of vital significance to ensure production safety and prevent accidents. The following is a detailed discussion of the safety facilities and equipment configuration of the short-range distillation unit.
