Molecular Distillation is a special liquid-liquid separation technology, which is carried out under high vacuum environment. It uses the differences in the free path of molecular motion of different substances to achieve separation.
Molecular distillation technique has been successfully utilized in many areas, such as foods, flavors, cannabis/hemp, garlic oil, cod liver oil and chemical and pharmaceutical industries.
DOVMXtech is China's best quality Molecular Distillation / Thin Film Evaporator equipment supplier.
There are three types of DOVMXtech series molecular distillation:Glass Molecular Distillation Unit, Hybrid Molecular Distillation Unit, Stainless Steel Molecular Distillation Unit. These are mainly applicable to the pilot production scale, especially the separation and extraction of high-quality hemp oil CBD / THC, fish oil EPA / DHA and plant essential oil.
Our short path molecular distillation system is very suitable for distillation/purification of heat sensitive material or high boiling point material. DOVMXtech wiped film molecular distillation unit has been widely used in fine chemical industry, medicine, perfume, essential oil, food and other industries. It has advanced technology, safety and reliability, convenient maintenance and continuous unattended operation.
Natural vitamin E is widely present in the green part of aloe vera and in the embryo of grass seeds. In the vitamin industry, both synthetic and natural vitamins require the use of molecular distillation technology in their production process. Molecular distillation is the preferred method for extracting natural vitamin E. Secondly, the use of molecular distillation technology can also extract natural vitamin A, which is also one of the early industrial applications of molecular distillation technology. With the continuous progress of technology, both molecular distillation technology and equipment have undergone significant changes, so molecular distillation is still used to extract natural vitamin A and other bioactive substances from cod, salmon, tuna, and other fish liver oils.
DOVMXtech wiped film molecular distillation is specifically designed and optimized for the extraction and purification of vitamin A and vitamin E. After treatment and purification, the purity of vitamin A and vitamin E can reach over 98%.
By eliminating common bottle necks, and enhancing the condenser configuration, we have created a machine that is more intuitive and efficient. Great for batch distillation or continuous processing, these systems come with heated gear pumps, and the option of rollers or wipers.
