Liquid Liquid Extractor - LLE / Extractor | Concept Process Equipments

Liquid – Liquid Extractor (LLE) is having shell with eccentric agitator giving a series of mixers and settlers. It is a mass transfer equipment where desirable component from liquid feed is get extracted in immiscible solvent which has greater affinitytowards desirable component in feed. After extraction we get, solvent with desirable component as extract and feed with very little of desired component as raffinate. Continuous and dispersed phase is decided based on properties of two phases. Concept process equipment is ISO certified company established in year 2014 with strong motivation and objective to manufacture value for money process equipment, which could offer as low as payback period of less than 6 moths to our customer majorly in distillation and drying areas, based on a thin film technology. We deals in pharmaceutical, food and chemical industry. We can proudly say that, we have 25 years plus of similar field experience, with which we can not only manufacture equipment’s but also help to our prestigious customer in conceptual process studies, basic and detail process designing of systems, installation as well as commissioning. We believe in provide best services to our customers satisfaction. To build the confidence before taking commercial decision of huge investment, mobile lab/pilot plant set-ups available on rent basis. We are committed to deliver continual improvements, growth, quality, safety and service. Operating principle of short path distillation unit (SPDU) is similar to thin film evaporator except internal condenser. Here internal condenser is installed inside rotor cage assembly. The feed enters the unit at top and get distributed into a thin film on the inside surface of shell. Heating medium passing through the jacket evaporates volatile component in feed. The vapor generated flow across the rotor and condense on internal condenser. This short path of vapor eliminate pressure drop. Hence evaporation can be done at high vacuum as 0.001 mbar(a). The distilled product and balance bottoms are taken out through separate outlets. High vacuum distillation of bulk drugs, natural or synthetic vitamins, esters, 7 epoxy resins, fatty acids, glycerides, tocopherols. Operation pressure as low as 0.001 mbar(a). Hence production can be distilled at lower temperatures to avoid degradation The Wiped Film Evaporator (WFE) is used for concentration, distilling, stripping, dehydration and deodorisation of products which are heat sensitive or viscous. The equipment can handle a very wide range of feed compositions ranging from 1% to over 95% concentration. WFE has several advantages as stated in the table below. The operation is continuous with a single pass; the self cleaning continuous contact wipers produce and renew the thin film. Such an operation improves product yield, avoids residue and colour formation. It has an internal condenser (optional) that minimizes the pressure drop and maintains vacuum. The operation process in the WFE is simple but yet effective. Feed is introduced at the top of the unit and spread on the shell inner surface by the rotating distribution plate. Specially designed wipers wipe the feed thus creating and renewing the film. This thin film enables an efficient heat transfer even for highly viscous fluids. The low boiling component evaporates and passes through an entrainment separator. This minimizes the carry over of liquid droplets along with the vapors. The vapors are removed through the vapor line to an external condenser (optional) and condensed. For specific applications which demand low pressure drop, the central section of the evaporator is provided with a condenser, thus making the unit a short path/molecular distillation unit. In this case, the vapors are allowed to condense on the outside of the tube bundle and flow out of the vaporator via the condensate outlet provided at the centre. A Rising Film Evaporator (RFE) is combination of vertical shell & tube heat exchanger and vapor- liquid separator mounted on top. The feed is given at bottom of shell & tube type heat exchanger and rises in tubes. Heat is given on the shell side by heating medium. As feed receives heat, vapor generated pushes the liquid on the wall as a film and lifts the liquid upwards. The mixture of liquid & vapor are separated at top in vapor- liquid separator. Good thermal performance is achieved because of high velocity generated by vapor lift. This upward movement against the gravity has the direct effect of creating a high degree turbulence in the liquid. This is one of its biggest advantage for viscous products which have a tendency to foul against the heating surfaces. Forced Circulation Evaporator (FCE) is a combination of shell and tube heat exchanger, a separator and circulation pump. Circulation pump is axial flow pump with high discharge and low head. The Pump maintains good velocity of liquid in tubes. This combination with adequate hydrostatic head above top tube sheet suppresses boiling inside the tube. Therefore scaling of tube during evaporation is minimized. Rotary vacuum dryer offers clean, simple and effective method of drying wet cake, powder and even slurry.
