Marigold lutein oil

To undertake marigold lutein ointment extraction complete equipment project

Our company supplies marigold lutein ointment processing equipment (Marigold Extract extraction equipment) complete production line. Our company has many years of experience in equipment process calculation and design of marigold lutein ointment extraction project, professional team production and installation, customized 10-100 tons / day marigold granule processing capacity of ointment project equipment production line for customers. Qi Kun, chairman of the board of the company, invented the patented technology of "LPG oil extraction process", which is widely used in plant pigment extraction industry. At present, it has been widely used in marigold lutein ointment processing industry.

Now take the production line of 30 tons per day as an example to explain as follows:

1. Project Name: 30t / D marigold granules butane subcritical low temperature extraction lutein production line equipment engineering

2. Project scale: 30t / D workshop of lutein extraction with butane subcritical low temperature in marigold granules.

3. Project content

3.1 provide a complete set of process design, equipment selection and layout;

3.2 provide power distribution electrical system and equipment lighting of supporting production line;

3.3 provide the civil engineering condition drawing design (excluding construction) of the supporting production line;

3.4 the qualification team provides equipment installation, pipeline connection, electrical installation, commissioning and after-sales technical services.

4. Technical advantages of low temperature extraction of marigold ointment with subcritical butane

4.1 the processing cost is relatively low. As the solvent consumption for extracting marigold ointment is less than 8kg / T of raw materials, steam is not needed, and only 80 ℃ hot water is needed. The production cost is generally about 380 yuan / T of raw materials.

4.2 quality of marigold lutein ointment:

4.2.1 extraction rate: the extraction rate of lutein from Tagetes erecta by subcritical biological technology was more than 97%.

4.2.2 trans lutein

As the solvent (boiling point - 0.5 ℃) is used to extract marigold at room temperature (< 45 ℃) and the solvent removal is carried out at low temperature (< 55 ℃) and vacuum (- 0.085mpa) for a short time, the pigment extract will not be oxidized or carbonized when removing the solvent. The pigment obtained has a high preservation rate, the content of trans lutein is generally more than 70%, and the solvent residue in the pigment is low.

4. 3. Meal quality

When marigold meal was leached by subcritical biotechnology solvent, the temperature of solvent removal was generally 45 ℃ ~ 50 ℃, vacuum (- 0.085mpa). The protein in the obtained meal was not easy to be destroyed, and the water content was less than 10%. Can be widely used in pigs, chickens and other feed, welcomed by farmers.

5. Brief introduction of technological process

Under normal temperature and certain pressure (0.3mpa-0.8mpa), marigold granules were extracted by subcritical biotechnology countercurrent. Then the solvent in the extract and meal was vaporized under reduced pressure. The vaporized solvent gas was compressed by compressor, condensed and liquefied before recycling. During the desolvation process, part of the heat absorbed by the solvent vaporization comes from the system itself, and the other part is supplied by the heating system.

6. Process flow diagram:
