Technic Characteristic and Application
Fields
与普通有机溶剂提取法相比，超临界CO2萃取技术具有无毒、常温、不易燃、无污染等特点，可确保原有的色、香、味不因受热破坏；更能确保其中热敏性、易氧化物质不被破坏；更为可贵的是在萃取过程中可同时对萃出物进行分离纯化。该技术适宜于萃取高价值的油脂（包括天然功能性油脂和天然药物中的油脂）、精油、内酯等极性较低的天然产物有效成份，在食品、香料、医药等行业中有广泛的用途。
Extraction may be defined as the decomposition of mixtures
into the individual constituents by means of suitable solvents, traditionally
low-boiling organic substances, such as methanol, ethanol, dichloromethane,
etc. However, because some of these substances are toxic and now being made to
avoid their use. A substitution to these solvents is Supercritical CO2.
This extraction method is based on the principle that substances dissolve at a
much higher rate in supercritical CO2 than would normally be
expected at a given vapor pressure. CO2 has proven especially well
suited for the extraction of natural substances. The low critical temperature
of31℃allows particularly gentle handling
of natural substances. Moreover, CO2 is not only readily available,
but may also be obtained at relatively low prices.
操作流程
Operate Flow
液体CO2由高压泵2加压到萃取工艺要求的压力并传送到换热器3，将CO2流体加温到萃取工艺所需温度后进入萃取器4，在此完成萃取过程。负载溶质的CO2流体在分离器中改变温度压力，溶解度降低使萃取物得以分离。分离萃取物后的CO2流体再经换热器液化后回到储罐1中循环使用。
Liquid CO2 flows collecting vessel (1)
to pump(2),which compresses it to the requires extraction pressure and
transfers it to heat exchanger(3), where it is heated to the extraction
temperature and transferred to the extraction vessel or column (4). The
substances to be extracted are dissolved in the CO2 as they pass through
the extraction vessel or column (4). The CO2, laden with the
dissolved substances is then fed to separator (5). By adjusting the pressure
and/or the temperature, the dissolving power of the CO2 inthe separator (5) is reduce, thus
causing the extracts to be precipitated. This may take place in several stages,
thereby allowing extract fractions of different qualities to be obtained. The
gaseous CO2 from the separator is liquefied in a refrigerated
condenser (6) and collected in collecting vessel (1). The use of several
extraction vessels for the extraction of substances in the solid state permits
virtually semi-continuous operation.

分子蒸馏
Molecular Distillation Technology
技术特点及适用范围
Technic Characteristic and Application
Fields
分子蒸馏是一种在高真空、低于沸点的条件下，利用分子热运动程度不同的特点完成的液体分离过程。分子蒸馏是在高真空（1Pa以下）下进行的，且被蒸馏物受热时间很短，能确保一些高沸点而又对氧、对热敏感的有机物质在蒸馏时不会被氧化、聚合、分解而变质。因而特别适用于高沸点、热敏性物质的分离。在医药、油脂、香料、化工等工业部门都有广泛的前景。
Molecular distillation is a kind of special high vacuum
distillation. Some organic compounds with high boiling point may not be distilled in conventional conditions
because thermal decomposition and/or polymerization occurs temperatures below
their boiling points. Molecular distillation is operated at high vacuum
condition (bellow 1 Pa), in which the materials are distilled at temperature
below their boiling point and heated in a very short time (generally tens of
seconds). Hence some easily oxidized and heat-sensitive organic compounds with
high boiling point are assured not to be deteriorated in molecular distillation
due to oxidization, polymerization and decomposition. So it is a very suitable
technique for separation of multiple-component organic materials, the
refinement of oil and fat, the concentration of Vitamin and the decolorization
of final products. Guangzhou Masson new separation technology company Ltd is
specialized in manufacturing the laboratory and industry Molecular distillation
equipment for about 30 years and welcome the clients for purchasing the
equipments. Also we provide this advanced technique to the clients for their
equipment refreshment and creating more economy benefit.
操作流程
Operate Flow
图中被蒸馏物的物M进入预热器1预热，然后经泵P1输送到蒸馏柱2进行脱气处理，再由泵P2输送到蒸馏柱子3进行****次分离，馏出物M1经泵P3直接输送出来，剩余的物料再经过泵P4输送到蒸馏柱4再次分离。馏出物M2从泵P5送出。剩余物M3从泵P6送出。
As the operating process shows,the raw material is
fed into the preheater (1), and heated,than pumped into the distilling
column(2) by pump(P1) for degasification, All of that, it is transmitted by
pump(p2) into distilling column (3) for
the first stage separation, Then the distillate M1 is dischanged directly by pump
(p3) and the residue is transmited by
pump (p4) into the distilling column(4),for the second stage separation. at
last, the distillate (M2) is pumped out by (P5) while the residue (M3) by (P6).
装置特点
Equipment Characteristic
1、操作真空度可达1Pa以下，因此蒸发温度可大大降低，特别适合于高沸点、热敏性物料的分离；
2、物料在蒸发面上形成薄膜，传热效率高，蒸发速度快；
3、物料停留时间很短，避免物料长时间受热而变化；
4、蒸发部分快速得到冷凝，避免产品裂解
The operation pressure can be less than 1
Pa, then the evapourating temperature can be much decreased, ideal for
separating materials with high-boiling point and thermal decompositine
substances ;
A piece of thin film will be formed on the
surface of the raw materials during evapouration, which increase the efficiency
of heating and evapouring;
It can prevent the materials from
transmating when heated for a long time because the material is transmit stage
by stage swiftly;
the evapourated condences rapidly,thus the
products decomposition.
