3.Spices and traditional Chinese medicine,pepper, mustard seed, purple perilla, etc;
4.Good quality oil,pure physical squeeze, high oil, does not destroy the organic components of oil.

Raw material

Without shell nuts (sea coconut), maple seed kernel (traditional Chinese Medicine), seed kernel (traditional Chinese medicine),Cinnamomum camphora (traditional Chinese Medicine), castor bean (traditional Chinese Medicine), five seeds, safflower seed and so on.

Working priciple

Generally, sunflower oil production line does the following manufacturing processes: cleaning of the seeds, grinding of the seeds, pressing and extracting crude oil from these seeds, and then further refining the oil obtained before packaging.
Cleaning the Seeds
The harvested oil-bearing seeds are passed over magnets to remove any metal traces, and other impurities are being got rid of by cleaning sieve and destoners. Then the outer covering (hulls) of the seeds are removed to obtain pure seeds.
Grinding the Seeds
The de-hulled seeds are ground into coarse meal to provide a larger surface area to be pressed. Hammer mills or grooved rollers are used to crush the coarse meal into uniform fine particles. Then the meal is heated to enable oil extraction, though impurities are released with oil during this process and such impurities should be removed before the oil is declared edible.
Pressing
The heated meal is fed into a screw oil press which progressively, at the same time, the oil is squeezed out through the slots in the barrel and recovered.
Refining of the Oil
Oil refining involves removal of the bitterness, color, and odor. First, the oil is heated at temperatures between 40 0C and 85 0C. Then it’s mixed with an alkaline substance like sodium carbonate or sodium hydroxide. The oils are degummed by treating them with heated water at temperatures between 85 0C and 95 0C or with acidified water. This precipitates out most of the gums usually phosphatides. Then centrifugation is done to remove the dregs.

Advantage

1. High oil yield, low oil residual in cake. The oil left in cake is less than 6%; The cake thickness can be adjusted when machine stops running;
2. Pure oil quality: Machine surface is made of stainless steel, in line with food hygiene standards; Besides, with two vacuum oil filters, residual can be removed by simple filtering;
3.This machine has simple structure and it is easy to operate.
4.It has high oil extraction rate ,and the oil is of fine quality.
5.Oil press machine is fully adopted mechanical driven, it connects a series small oil processing equipment together to realize continuous oil extraction with easier operation and higher rate of oil yield.
