Sunflower seeds preparation & oil pressing line

Generally, large scale sunflower seeds oil pressing line has two parts--sunflower seeds preparation and sunflower seeds oil pressing. Specifically speaking,the whole sunflower seeds preparation and oil pressing line include sunflower seeds cleaning, dehulling, nut&shell separating, flaking, cooking, pressing seven steps. Henan Doing Company can manufacture 30-2000tpd sunflower oil pressing line and provide turn-key project service for customers. The following is the details about large scale sunflower seeds oil pressing line.

1. Sunflower seeds preparation part:

Sunflower seeds has two kinds, edible sunflower seeds and oil sunflower seeds. Oil sunflower seeds has high oil content, 45-54%, which is one of main oilseeds in many countries. First of all, using oilseeds cleaning machine to remove impurities from sunflower seeds, prevent damage to the machine.

A complete set of sunflower seeds dehulling machine can remove the shell of sunflower seeds and separate peel and seeds. And the sunflower seeds that didn't dehull can return to the sheller automatically. The advantage of dehulling sunflower seeds is to get high oil yield and better oil color.

Sunflower seeds flaking machine:

It is the process of making use of the mechanical action to flake the sunflower seeds. Sunflower seeds flaking machine is to destroy sunflower seeds tissue, and after flaking, the materials is becoming thinner than before. It is good for absorb moisture and heat in cooking process, and it is much easier for getting sunflower oil in sunflower seeds oil pressing process.

Sunflower seeds cooking machine:

Usually, use multi-layer oilseeds cooking machine. Mix the sunflower seeds flaker with steam, and adjust the sunflower seeds flaker with moisture 13-14%, at the same time cook the sunflower seeds flaker. Heating will increase oil yield and get high quality sunflower oil. It is a most important step before sunflower seeds oil pressing.

2. Sunflower seeds oil pressing part:

After flaking, sunflower seeds flaker will be sent to sunflower oil press machine. In large capacity sunflower seeds oil pressing line, we recommend sunflower oil pre-press machine, which is with an auxiliary roaster. It has high oil yield and long duration characteristic.

Specific parameters of sunflower oil pre-press machine:

Capacity 16~22t/24hrs
Power (kw) 30+15V(380V,50Hz)
Net Weight 5500 kg (approx)
Overall Dimensions(mm) 2900×1850×3640(L×W×H)
Electric motor Y225-M-6, 1000R.P.M. 30kw. 220/380V, 50Hz
Residual oil content in cake 13% (approx)

The feature of sunflower oil pre-press machine:

1. High capacity, less installation space, little power consumption and simple control & maintenance.

2. Pre-pressed cake, being loose but not crushed, is helpful to solvent penetration.

3. The percentage of oil and water content in cake are suitable for solvent extraction.

4. The sunflower oil got from the sunflower oil pre-press machine is of higher quality than that obtained by single pressing or single solvent extraction.
