GN has been leading the development of centrifugal decanters from 9 inches to 30 inches with high quality materials and durability, with technology and precision in the assembly, receiving good comments from our end customers every day. The centrifugal decanter that GN has been activating the increasingly efficient process industry and maximizing resources to the full.
One of the processes used by the centrifugal decanter for the development of separation of solids and liquids is the fish industry.
For the fishmeal process, it begins its flow with cooking for the coagulation of the protein, with this process the bound water and oil are released, the separation by pressing of the coagulated product obtaining), a liquid stage (Press Liquor ) containing water and the rest of the solids (oil, dissolved or suspended protein, other nutrients such as vitamins and minerals) and a solid stage called (Press Cake).
The main part of the sludge in the Press Liquor is removed by centrifugation in a Decanter and the oil is by default extracted by centrifugation, due to the high G forces that our GN Decanters have and their materials used make an efficient separation. The Cola Water is concentrated in a multi-effect evaporator and the Concentrate is mixed vigorously with the Press Cake, which is then usually dehydrated in a sedative. The dried material is ground and stored in bags or in bulk. The extracted oil is stored in custom-designed tanks for later use or treatment that may be done in another process.
The functionality that GN offers in its centrifugal decanters in its wide range of models allows preventive maintenance to be carried out in longer periods and with less economic impact, making the end customer maximize their production costs; seeing as the best option the GN Solids control equipment is a safe and guaranteed investment in the short and long term.
