4. Equipment Applications

A food industry

1. Production of monoglycerides

Molecular distillation rectification extraction technology is widely used in the food industry for the separation of mixed fats and oils to obtain food emulsifiers (monoglycerides of fatty acids)> 90% of high purity products. The use of molecular distillation and rectification extraction technology can obtain high purity products with monoglycerides >90%. This method is a commonly used and effective method in the industrial high-purity monoglyceride production method at present, and the monoglyceride can meet the requirements of food grade. Molecular distillation and rectification to extract monoglycerides gradually replaced ordinary monoglycerides with low purity and deep color. The market prospects are considerable. Molecular distillation and rectification to extract monoglycerides can bring huge profits to enterprises.

2. Refining of fish oil

To extract natural products from animals, molecular distillation and rectification extraction techniques, such as refined fish oil, are also widely used. Therefore, molecular distillation is an effective method to separate and purify EPA and DHA.

3. Deacidification of grease

In the process of oil production, the crude oil extracted from the oil contains a certain amount of free fatty acids, which affects the color, flavor and shelf life of the oil. The use of molecular distillation and rectification extraction technology has a good effect on the deacidification of high acid value oils and has broad application prospects.

4. Refining of high-carbon alcohols

High-carbon fatty alcohols refer to straight-chain saturated alcohols with more than twenty carbons, which have a variety of physiological activities. After extraction and purification by molecular distillation, the purity of high-carbon alcohol reaches w (higher alcohol) = 96%, of which w (octacosanol) = 16 7%. Using molecular distillation and rectification extraction technology to refine high-carbon alcohols, the process is simple, the operation is safe and reliable, and the product quality is high.

Application of B in fine chemicals

Molecular distillation extraction technology can be used in the fine chemical industry for the separation of hydrocarbons, crude oil and the like; the purification of surfactants and the preparation of chemical intermediates; the deodorization and decolorization of lanolin and its derivatives; plastic plasticization Refining agents and stabilizers, and refining silicone oils, paraffin oils, and high-grade lubricating oils. In the separation of natural products, many aromatic oils are refined and purified by molecular distillation to obtain high-quality essential oils.

1. Purification of aromatic oil

Molecular distillation rectification extraction technology is an effective method to purify essential oils. It can concentrate a certain main component in aromatic oil, remove odor and colored impurities, and improve its purity. It is carried out under high vacuum and lower temperature, and the heating time of the material is extremely short, which guarantees the quality of essential oils, especially for aromatic oils with high boiling point and heat-sensitive ingredients, which shows its superiority. Different types of effective ingredients and their relative contents can be obtained by adjusting different distillation temperatures and vacuum degrees, and relatively high effective ingredients can be obtained by adjusting suitable distillation temperature and vacuum degrees.

2. Purification of polymer intermediates

Molecular distillation rectification extraction technology can excellently protect the quality of polymer products, improve product purity, simplify the process, and reduce costs.

3. Extraction of lanolin

Lanolin and its derivatives are widely used in cosmetics. Separate the components by molecular distillation extraction technology, and modify different components by physical and chemical methods to obtain polyoxyethylene lanolin, acetyl lanolin, lanolin acid, isopropyl ester and wool polyoxyethylene resin, etc. Lanolin products with excellent performance.

Biology, home textiles, etc.

5. Equipment features:

1). Ordinary distillation is carried out at the boiling point temperature. The molecular distillation extraction equipment can be carried out at any temperature. As long as there is a temperature difference between the hot and cold sides, the separation can be achieved.

2). Ordinary distillation is a reversible process of evaporation and condensation. The liquid phase and the gas phase can form a phase equilibrium state; while in the molecular distillation extraction process of molecular distillation, the molecules escaping from the evaporation surface directly fly to the condensation surface. It does not collide with other molecules, and theoretically there is no possibility of returning to the evaporation surface. Therefore, the molecular distillation process is irreversible.

3). Ordinary distillation has bubbling and boiling phenomena; the molecular distillation extraction process is free evaporation on the surface of the liquid layer without bubbling.

4) The separation factor of ordinary distillation separation ability is related to the ratio of the vapor pressure of the component, and the separation factor of molecular distillation extraction separation ability is related to the ratio of the vapor pressure and molecular weight of the component, and can be obtained from the relative evaporation speed.
