Specifications of sunflower seed  oil prepress machinery :

Cooking oil press machine

1.Pre-pressed cake residual oil≤14-16%

2.Noiseless oil press equipment 

Brief description of sunflower seed oil pre-pressing  machinery  and its advantages:

1.Continuous production,  stable product quality, low energy consumption;

2. Adopt spiral oil press with high production capacity, which obtains the advantages of large production capacity, less power consumption, low transportation cost and residual oil rate, the structure of dry cake is loose and uncrushable, and it is easy for solvent penetration.

 Technology process of sunflower seed oil pre-pressing machinery :

1. Dehulling process

Cleaned  sunflower seeds  are crushed into the toothed roll decorticator (two pair). Then oilseeds are squeezed strongly by the relative rotation of the two fluted rollers with different linear velocity.

Moreover, the alveolus can split and cut the hulls of oilseeds. Thus the dehulling effect will be achieved. 

2. Kernel and hull adjustment

The separated sunflower seeds kernel are conveyed into the kernel and hull adjustment screen through the conveyer scraper, because the higher hull content in the kernel is, the lower protein content in the finished sunflower meal is. Due to the need of cotton meal with different protein content in the market, the process is mainly to adjust the hull content in sunflower seeds kernel and process cotton meal with different protein content.  

3.Flaking

 The main purpose of flaking is to destroy cell wall within sunflower seeds kernel so that oil within sunflower seeds kernel can be extracted out.After the process of flaking,the thickness of material will be reduced and its surfacearea will be increased,which are in favor of moisture penetration and heattransfer towards the inside of particle in the cooking process.

4. Cooking

After wetting, heating, steaming, frying and other processing, the raw embryos come up complicated physical chemistry change in its interior and become mature embryos. Thus creating a better condition to extract the oil, the heat treatment process is called cooking.

5.Pressing process

Embryos after cooking are called cooked flakes,crude oil containing slagsfrom presser is pressed into oil settling tank through oil scraper blade,after the slag is removed,the crude oil is sent into oil filter tank,and then itis sent into horizontal screw centrifuge for purification.Pre-pressed cake from oil presser is conveyed into extraction plant by cakecollecting scraper and cake scraper, and thenenters into the following process.

YZCL series cooker is a main equipment in oil production, mainly used for the cooking of vegetable oil seed. By moisturizing, steaming and cooking, the flaked seed turn into cooked flakes, which fulfills the requiremnt of prepressing and improves the quality of oil.

 

Model ZY28 oil press is a large continuous oil extraction equipment suitable for one press, such as rapeseed, cottonseed, tung-seed, sunflower seed, cottonseed and other high oil contained plants seed oil press. The advantages of the equipment are as follows: large processing quantity, low power consumption, low running charge, pre-pressed cake with good structure and easy solvent permeation, low residual oil content, etc.
