Peanut pretreatment & pre-pressing machine is the first step to process peanut and get peanut oil.Peanut processing generally refers to the process of extracting oil from oil seeds. The whole peanut oil processing begins with oilseed cleaning, and ends with oil refining.The peanut pretreatment & pre-pressing machine include cleaning section, crushing section, flaking section, softening section, cooking section and oil press section.

Peanut pretreatment & pre-pressing machine before peanut oil extraction:
Different kinds of oilseeds have different oil content and physical properties. So the pre-treatment process varies slightly from one kind of seed to another. But most seed pre-processing includes cleaning, husking, crushing, flaking,cooking and cooking. Below are typical oil seed pre-treatment processes of soybeans, canola seeds and sunflower seeds.

Peanut oil extraction machine——cleaning machine

Cleaning: Remove impurities such as leaves, sticks, stones, sand, dirt, spoiled seeds and metal contaminants. This processis commonly referred to cleaning and scalping equipment including sieve, destoner, peeling machine, magnetic devices, and beltconveyor etc.The cleaning machine is good for peanut oil pretreatment and pre-pressing machine.

Dehulling: Most oilseeds need to remove the abrasive shells before oil extracting, since the oil content of shells and hulls is less than 1%. Besides, shelling can not only improve the capacity of oil extraction equipment, increase the efficiency of oil production, but also can reduce wear of oil expeller. Dehuller is commonly used in peanut oil pretreatment and pre-pressing machine.

Crushing & Flaking: Most oilseeds require size reduction prior to oil extraction. Crusher and flaker are used in peanut oil pretreatment and pre-pressing machine. Some small seeds such as corn germ, rapeseed and canola don’t need to be cracked.

Peanut oil extraction machine —— cooking machine

Cooking: Heating the seed is an option, but not necessary. It can increases efficiency of extraction and protein availability.

Peanut oil extraction machine——prepressing machine

Pre-pressing:The oilseeds pre-pressing machine adopts domestic mature DY series pre-presser which specialized for peanut, the oil residue in cake after pre-pressing is about 10-18%, the peanut cake can adopt solvent extraction method to get more oil. The most features of this machine is low energy consumption, less occupied area, etc which is the first choice for peanut pre-pressing.
