Rotary evaporator evaporating suspensions, initiating crystallization used in dairy, food processing


Rotary Evaporator

Rotary Evaporators are mainly used to evaporate light boiling components under normal pressure or vacuum. When used in pilot plant and small scale production they are also suitable for semi-continuous evaporation. They are characterized by providing a gentle thermal treatment for temperature-sensitive mediums and provide a higher evaporation rate as non-stirred glass distillation flasks. Compared to other evaporation processes the unique process feature of rotary evaporators is their ability to evaporate all volatile media providing at the end a dry product in the flask. The process conditions are limited by the maximum temperature of the heating bath ( max. ~ 180°C) , the temperature of the cooling liquid (e.g. ~ 15°C tap water) for the condenser and the vacuum generator ( e.g.~10mbar).The liquid to be processed in the rotary evaporator is either charged batch wise by garvity, by a pump or succed-in by vacuum into the evaporation flask. During the evaporation process further feed can be added by means of a pump, gravity or by the operating vacuum through the PTFE-hose pasing the rotating shaft and ending in the spherical vessel.

Rotary Film Evaporator

Rotary Film Evaporator is preferred by both research and production facilities and has been used by laboratory and chemical, pharmaceutical and biotechnological industries. It is essentially a thin film evaporator. The rotating flask continuously covers a large surface area with a thin film which is ideal for rapid heat transfer. Fortuitously, the thin film also ensures uniform heat distribution without local heating. The facility to work the unit under full vacuum further facilitates evaporation at as low temperature as possible. It is suited for evaporation of heat sensitive material. It is equally successful for evaporation of suspension in crystallization processes, drying of powder/ granules etc.

Rotary Film Evaporator

Rotary Film Evaporator glassware consists of an evaporating flask, a receiving flask & a condenser. The evaporating flask holds the sample to be evaporated. Once a sample is placed in the evaporating flask, it is lowered in to a heated water bath and is rotated in the water bath. The rotation of the evaporation flask creates a thin film of sample on the inside of the glassware. Increase surface area encourages evaporation of the molecules. Heated water encourages the free flow of molecules to move toward the condenser to be collected in the receiving flask. The receiving flask collects the condensate that comes from the condenser for evaluation of the pure solvent or proper waste disposal.

Rotatory Evaporators

Rotatory Evaporators principle is the most universal method, as it is an efficient, fast and gentle way to separate liquids. The rotating flask continuously covers a large surface area with a thin film, which is ideal for rapid heat transfer.The facility to work the unit under full vacuum further facilities evaporation at as low temperature as possible. These features, combined, renders rotary film evaporator to be ideally suited for evaporation of heat sensitive material. It is equally successful for evaporation of suspension in crystallization processes drying of powder / granule etc.Rotatory Evaporators is designed especially for solvent separation-miscible & immiscible, crystallization. Its control panel located on the front of the unit thereby protecting the user from the hot water bath,construction of vacuum seal is made of PTFE, which extends its life and reduce down time,indigenously developed vacuum seal mechanism in PTFE giving competitive edge against well-established Rotary flask of International or other Indian make.

Wiped Film Evaporator

Wiped Film Evaporator 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. 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.
