Decanter

Continuous centrifugal extractor with a horizontal axis auger is able to separate a solid phase from one or two liquid phases.

Since 1982 Ghedini Srl has been alongside companies, supporting them in various production and operational processes: we sell, buy, rent, install, repair, test and maintain decanter centrifuges for the best national and international brands.

Decanter centrifuges are indispensable in industrial production processes for many sectors: from the processing and refining of cooking oils and vegetable fats to the extraction and purification of wine, must and sparkling wine; from the chemical and pharmaceutical industry to the ecological sector; from the separation of animal fats to the chemical recycling of polymers; from the processing of fruit juices and multiple vegetable drinks to that of algae and precious metals.

Solid particles that have a higher specific gravity than they do in their liquid phase go outwards forming a layer that will be extracted by the augers.

Unlike separators, decanter centrifuges can be used for processing substances with a high content of solid parts.

Here are the main types of decanters:

  • Two-phase decanter: this type of decanter is used to extract the solid particles suspended in a liquid
  • Three-phase decanter: this type of decanter is used to separate the solid particles from a light liquid and a heavier liquid

Decanter maintenance

Decanter centrifuges need careful and periodic maintenance to sustain efficient performance in various fields of application: Ghedini Srl is a reliable partner that, for forty years, has stood alongside companies that use these machines in their operational and production processes.

Yeast

In yeast production, vertical nozzle centrifuges are often found.

Food flavors

The industry uses a huge variety of flavored extracts. These are produced using enzymes and/or alcohol and then distilled so that the alcohol separates from the dissolved flavors.

Vegetable degumming

Degumming is the process of refining vegetable oils where compounds that cause defects in the oil’s characteristics and preservation problems are removed, essentially extracting the gums (phospholipids).

Animal degumming

Similar to vegetable degumming, it is also possible to perform animal degumming, starting with animal-based oil (tallow).

Vegetation water

Vegetation water is a byproduct of the three-phase olive mill process.

Fish oil

The fish waste is cooked, and from the cooking process, we obtain an aqueous solution rich in solids (biomass). First, the solids need to be separated from the liquid, and a solid-liquid decanter is the suitable machine for this process.
