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.
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.
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.

Edible oils and fats can be refined chemically or physically. Either way, GEA has extensive expertise for both process types.
Crushing
During crushing the crude oil is obtained from the original feedstock. Seeds are usually pressed while beans require extraction to separate the oil from the rest. Examples for seed oils are canola and sunflower, a typical oil bean is soy. Pressed oils are clarified in a decanter stage before the gums are removed by water degumming.
Press oil clarification
Feedstock: all oil types that are pressed, i.e. rapeseed or sunflower.

Benefits:
Water degumming
Feedstock: all oil types, beans or seeds, from pressing or extraction

If the chemistry is right..
... free fatty acids don't stand a chance. The caustic soda added to the crude oil reacts with the FFAs to form sodium soaps. Centrifugal separators then remove the soaps from the crude oil. The neutral oil is subsequently bleached and deodorized. This method can be used for reliably refining virtually all crude oils, including oils of low quality, with the exception of castor oil.
In chemical refining caustic soda is used to neutralize free fatty acids.
The standard neutralization process is called exactly this, Standard Neutralization. It is the most common method to neutralize pre-degummed oils or oils with only a low phosphatide content.
Feedstock: Virtually all oils, including and especially low quality oils, except castor oil.
What to consider:
Benefits:
Cold refining
Feedstock: for oils that contain waxes and have relatively low FFA contents, e.g. sunflower oil

Soapstock splitting
In physical refining the free fatty acids are removed by distillation in one stage during deodorizing. This method requires lower investment and is simpler in installation and operation compared to chemical refining. However, crude oils that are refined physically have to be degummed as far as possible because residual gums affect the oil quality during the extensive heat treatment in distillation. For some oil qualities this is only possible to a limited extend. Other oils, i.e. cottonseed or fish oil, are fundamentally not suitable for physical refining.
The crude oils from the crushing plants still contain high amounts of phospholipids. They have to be removed as they harm the oil's storage stability as well as further processing. Some phospholipids can be hydrated (HP), some cannot (NHP). Most of the HPs have already been removed during water degumming. Thus, the degumming stage in physical refining attends to the NHPs. There are myriad of possibilities to engineer a degumming stage, the actual realization usually depends on customer preferences and oil type and quality respectively. In general, we recommend either TOP or cold degumming (aka dewaxing). Why? Read on, please.

TOP degumming
What is so top about TOP degumming is that it is the only degumming method without waste water.
Feedstock: all oil types that do not contain waxes
What to consider:
Have we mentioned that this is the only degumming method that does not produce waste water? Well, it does incur of course, at least to some extend, but we have set up the process in such a way that the water is constantly recycled.
Benefits:
Cold degumming
Feedstock: for oils that contain waxes: sunflower, olive pomace or corn oil
What to consider:
You can also opt for dry dewaxing, a process that goes without centrifuges. In return you get higher product losses and filter aids. And with them the constant dealing, purchasing and disposal of the same. So either way, you have to invest. The question is only into what.
