Centrifuge
Separator RSE / RSI for Edible Oil Refining
GEA offers an extensive portfolio of separators for the refining of edible oils, both from vegetable as well as animal origin. The disk-stack centrifuges are used for degumming, neutralization and dewaxing process stages and are ususally the heart of the process lines.
Fine-tune your separation results
Our oil refining separators feature the GEA finetuner, a combination between a centripetal pump and a paring tube. It is characterized by a substantially improved efficiency factor compared to conventional centripetal pumps.
This is the ratio of the conversion of rotational energy into pressure. The effect is viscous media such as gums from super degumming installations can be discharged without difficulty. The adjustment of the finetuner diameter can be done by a manual hand wheel or by a pneumatic actuator from the control unit.
Working principle of RSI separator with finetuner and integrated direct drive
Maximum uptime with Integrated Direct Drive from GEA
There are different drive concepts available for our oil refining separators: the conventional gear drive, flat-belt drive with power transmission from the torque-controlled motor to the bowl spindle vial single flat belt, direct drives with the motor directly mounted to the spindle and the newest evolution in drive technology from GEA: integrated direct drives. The integrated direct drive also transfers the motor power directly to the bowl but is integrated into the centrifuge’s housing.
Thus, our separators need up to 35 percent less space and operate much more quietly. The entire technical concept has been simplified and the number and variety of parts reduced. Bowl and motor can both be removed as a single entity reducing the downtime for maintenance considerably. . Our integrated direct drive concept maximizes the availability of our separators making sure your oil mill is working to capacity.
Edible oil refining separator series RSI
Resource efficient solution
The GEA Advanced Water Supply optimization concept is an example of how further savings potential can be unlocked at any point within the process chain. In this case, it is the smart reduction of the consumption of cooling and operating water without any negative impact on performance.
With optimized control matched to the technical conditions, it is possible to optimize the consumption of operating water for a self-cleaning centrifuge as well as the cooling water for the direct drive, the hood, and the solids catcher, resulting in water savings of minimum 48%.
*The Add Better label relates to the serial product Edible Oil Refining Separator RSI, released in November 2024.
The comparison refers to its predecessor model, the RSI series without GEA Advanced Water Supply.
Gentle product treatment for highest yields
The hydrohermetic feed system developed by GEA protects the product from exposure to the high shearing forces, which would break up the gums or soap particles and consequently making separation a lot more difficult. Emulsification is avoided at this point especially during washing and winterisation. The also featured hydrohermetic vapor seal (sealing by liquid) prevents vapors from rising out of the feeding chamber into the lower centripetal pump chamber. This has a positive effect in case of higher separating temperatures (> 90°). Additionally, liquid can be fed into the bowl through a separate bowl flush water channel.
Features & Benefits:
GEA finetuner
- For optimum adjustment of the separating zone
- Flexibility of the separators: a single machine can carry out all refining processes without the need for converting the machine
- For improved operating reliability and no oil losses
Hydrohermetic feed
- Protects the product from exposure to high shearing forces through gentle product feed
- No mechanical seal and therefore no additional cooling water consumption
- No oxygen pick-up
Hydrohermetic vapour seal
- The hydrohermetic seal prevents vapours in the inlet space from causing turbidity in the oil
Bowl flush
- A highly viscous heavy phase can be diluted to improve its flow characteristics
- Also available for use in explosion hazarded surroundings
Integrated direct drive
- Very small footprint
- Fast maintenance and maximum availability
- Reduced energy costs due to direct power transmission
- Fewer wearing parts
- Reduction of noise level
- GEA direct drives meet all explosion proof requirements
