Sparktech offers customized machine solutions for any application ar process to meet the individual  requirement of the customers

Different  degumming  prooesses, are carried out to remove phosphatides .For efficient and economic application of this procedure.

SPARKTECH  provides appropriate machines and equipments.

Water degumming

A large part of  the phosphatides (gums) cab be hydrated quickty and easily. If the pressed or extracted oil contains a considerable quantity of  gums the oil is subjected to the water decumming process immediately following extraction. In this process, Water added  to the oil. Arter a certain reaction period the hvdrated phosphatides can be seeparated either by decantation (settling) or continuously by means of centrifuges.

In  this process step a large part of hvdratable and even a small proportion of the non-hydratable phophatides are removed

The extracted gums can be processed into lecithin for food, feed or technical purposes.

The gum content in the ail is subsequenciy reduced according to the refining quality requirements.

in principle,the combination and concept of further processing stages in distinguished by

·         chemical refining and

·         physical refining

In chemical refining the free fatty acids are neutralized by caustic soda resulting so-called"soap stock"which is also seperated either

by decantation or continuously by means of centrifuges.

Simultaneously the non-hydratable phosphatides are also separated in this process.

In physical refining the gum content can be further reduced by different processes:

·         Dry acid degumming or

·         wet acid degumming.

Dry acid degumming

Dry acid degumming is particularly suitable for processing ails with law gum contents such as palm ail, coconut oil, palm kernel oil or animal fats. Intensive mixing is implemented following addition of acid to the pre-heated crude oil. The conditioned gums are absorbed into the bleaching earth and are separated by filtration.

The benefits of the dry acid degumming process are:

Efficiency as a result of

·         low energy consumption.

·         low operation and maintenance costs(sturdy and reliable control system),

·         long service life(the components are acid proof],

·         minimum footprint,

·         low investment costs,

·         environmental-friendly as no wastewater or soap stock occur.

wet acid degumiming

intially oils with higher gum contents (e.g corn oil) are similarly processed as in dry acid degumming.However, to achieve gum hydracion water is added  following acid apportioning  The gums are removed by a separation prior to bleaching. The process is beneficial as

·         centrifuges enable easy separation of gums in oil types with higher non-hydratable gums contents (e.g rape oil and saybeen oil )

·         The consumption of bleaching earth s reduced because the oil has allready been extensively degummed

Dry or wet acid degumming are not always sufficient to reduce gums to the value required in the oil prior to the combined deodorization and distillation process

 Thus we have developed a special degummimg process
