Description of the equipment

The rotafilm apparatus is designed for drying of the hydratable sludge (gums) releceived during the hydration of the oil.

Operating principle

The rotafilm apparatus is a horizontal vessel mounted on a frame, with a steam jacket and a conical rotor rotating inside. The phosphatide emulsion is supplied to the blades of the conical rotor Due to the centrifugal forces emulsion is spread over the inner surface of the housing and gradually moves in the form of a thin film along the housing. The steam-gas mixture resulted by evaporation is aspirated by a vacuum system, and the phosphatide concentrate with a residual moisture content of less than 2% is discharged into a storage container or for further processing.

Frequently Asked Questions about Rotary Film Machines
What is the principle of operation of rotafilm apparatuses for vegetable oil processing?
The rotafilm apparatus is designed for drying of hydration sludge (gums) separated in the process of vegetable oil degumming. Phosphatide emulsion is fed to the blades of the rotating conical rotor, under the action of centrifugal forces is applied to the inner surface of the body and progressively moved in the form of a thin film along the body. The vapor-gas mixture formed as a result of evaporation is sucked out by vacuum system, and phosphatide concentrate with residual moisture content less than 2% is removed to a storage tank or for further processing.
What are the advantages of rotafilm apparatuses?
Rotafilm apparatuses have a number of advantages: compact size and relative ease of machine maintenance and operation.
What is the price and lifetime of rotafilm apparatuses?
The price of rotafilm apparatuses depends on the model and equipment. The service life of rotafilm apparatus is from 10 to 20 years depending on the operating conditions and quality of service.
