Peanut peelerer for better peanut oil

Can the peanut pressed oil with the shell? Is it better to squeeze with a shell or without it?

Can the peanut with shell squeeze the oil?

Peanuts with shells can squeeze the oil.

However, the direct oil extraction of the shell peanuts without treatment will reduce the oil yield and quality of the peanut oil, and the soil, gravel and other impurities outside the peanut shell will also increase the difficulty of cleaning the equipment, and the impurities mixed in the subsequent wool oil will also be more, which will increase the difficulty of filtration. After the peeling peanut treatment, the subsequent pressing process will be more smooth, the oil and the oil cake come out will be more smooth. Therefore, Ruian Every Machinery recommend you press peanuts oil without shell is better.

Why do peanuts don't squeeze oil with a shell?

Frankly speaking, because the oil in peanuts is mainly concentrated in the peanut kernel, the amount of oil contained in the shell is very small. If the oil is pressed with a shell, not only does not produce the oil, but will absorb the oil residue in the oil cake, reduce the oil rate. On the contrary, before the peanut pressing, the peeling treatment, on the one hand, can speed up the oil rate, accelerate the quality of gross oil and oil cake, also conducive to reduce the wear of the equipment, prolong the service life of the equipment, increase the reasonable production of the equipment.

The conventional peanut oil process flow is shown as follows:

with shell peanut- -peeling- -cleaning- - -crushing- -flaking- -frying- - -pressing- - -filtering

At first, the peanut is peeled by the peanut peeling machine, and then the cleaning equipment is used to remove the impurities in the peanuts. Then, the peanuts are adjusted to a good state suitable for pressing by crushing, flaking and frying. Finally, enter the oil press machine to press and after simple filtration by the filtration equipment, the filtered peanut oil can be obtained.
