Crude fish oil production process
With the in-depth development of fishmeal processing, the deep processing of fish oil produced during the processing has been pushed to the forefront by the market. Our company has been well received by users since the three-phase horizontal snail was put into the fishmeal processing production line in 2011. In this production process, our company cooperated with some fishmeal factories to further improve the quality of fish oil in fish oil
production and developed a mature set. Deep processing of crude fish oil.
Fish oil from fishmeal factories and aquatic animal oils from oil-melting plants, although there are few water and
mechanical impurities in the oil, this oil does not meet the requirements of some advanced oils and further processing, and needs further refinement, including Detoxification, dehydration, deacidification.
Decontamination and dehydration can be treated together in the process of deacidification
Deacidification refers to the removal of free fatty acids from the oil. Free fatty acid content. It is an important indicator of the quality of fat, usually expressed as acid or free fatty acid (F.F.A)%.
Although there are many methods for deacidification, it is commonly used in the industry to use alkali neutralization methods such as sodium hydroxide (NaOH) or sodium carbonate (NaCO3), among which sodium hydroxide neutralization method is the caustic deacidification method. It is most common because in addition to being effective in neutralizing free fatty acids, this method also has a decolorizing effect. The disadvantage is that the neutral oil loss is relatively large. The process of caustic soda deacidification is as follows:
Determination of the amount of caustic soda (the amount of caustic soda required to neutralize 100 kg of oil)
Animal protein disc separator is mainly used for animal protein extraction and separation, also used for refining animal fat in meat processing, or used for fish oil concentration and separation in the processing of aquatic products. This model is also suitable for the mother liquor high content of heavy liquid separation and clarification treatment, to obtain a higher purity heavy or light liquid phase, Also apply to animal fats, offal, wool sewage treatment and other animal oil industry. Separator’s parts which contact with materials is made of stainless steel, conform to food hygiene requirements.
Welcome all who care engaged in the separation and filtration to work with us,and we are also looking for the qualified world wide agents to provide better service and deep marketing.
