Walnut oil leaching characteristics of equipment with leaching method, oil
1, the main equipment: there are many species of walnut oil equipment, mainly has intermittent, continuous.Continuous immersion, spray type and hybrid 3 kinds.All kinds of leaching is a continuous, advanced process equipment, production efficiency is higher.
2, the principle of leaching rule of oil, walnut oil equipment using the features of oil soluble in some organic solvents, can be in by squeezing the remaining bran bread in the kernel oil extraction, oil recycle nuclear, unlike in the boiling point of the solvent evaporation, kernel oil is separated from the solvent, this is the theoretical basis for oil extraction of legal system.In chemical unit operations is also known as stupid or extraction.This method due to high cost of solvent, rarely used in large-scale oil system in our province, is a chemical or chemical test chamber adopts.
3, oil leaching legal process: according to the raw material of different can be divided into direct leaching method or preloading method two kinds.Walnut oil content is high, should first after squeezing and will remain hard to squeeze out the oil in the bran bread, leaching method is used to extract.Squeeze can be broken into the oil leaching, after the process is: mixing oil evaporation Lv stripping, wet meal steaming, solvent recovery processes, etc.
4, leaching solvent and recycling: walnut oil equipment ideal leaching solvent should have the grease has good solubility, volatile, better chemical stability, non-toxic, not easy to catch fire explosion and boiling range is appropriate, in the water and small solubility properties.And low acid value, can guarantee the supply, etc.Widely used in our country at present the leaching solvent organic solvent are aliphatic hydrocarbons.
