Marigold lutein subcritical biotechnology extraction equipment

'' -: -: -:Subcritical biotechnology
'' -: -: -:Technical advantages of low-temperature extraction of marigold ointment

r__ '' -: -: -:, Low processing cost
-: -: -: Since the solvent consumption for extracting marigold ointment is less than 100%/raw material, no steam is required, only ℃ hot water is required. The production cost is generally around RMB/ton of raw materials.
-: -: -:, Marigold lutein quality
-: -: -:., Extraction rate:
-: -: -:Subcritical biotechnology
-: -: -: Extraction rate % of marigold lutein.
-: -: -:., Trans-lutein: Because the solvent (boiling point -.℃) extracts marigold at normal temperature (&;℃), the solvent is removed at low temperature (&;℃), vacuum (-.) is carried out in a very short time, so the pigment extract will not be oxidized or carbonized when the solvent is removed. The resulting pigment has a high preservation rate and a high trans-lutein content (generally above). Good quality pigments have low solvent residue.
-: -: -:, meal quality
-: -: -:Subcritical biotechnology
-: -: -:When solvent leaching marigold, the temperature at which the solvent is removed from the meal is generally The protein in the meal obtained when it is carried out under vacuum (-.) at ℃ ~ ℃ is basically not destroyed and the moisture content is low. It can be widely used in pig feed and is very popular among farmers; it can also be used in food. Selling price is high.
-: -: -:, safer

-: -: -:, process flow introduction
-: -: -:under normal temperature and certain pressure (.& ;.) Using
-: -: -:Subcritical Biotechnology
-: -: -:Counter-current extraction of marigold particles and then vaporizing the solvent gas in the extract and meal under reduced pressure It is then compressed by the compressor, condensed and liquefied, and then recycled. Part of the heat required for solvent vaporization during the desolvation process comes from the system itself and the other part is supplied by the heating system.
