Pretreatment Process

a. Cleaning device: To remove various impurities in oilseeds, such as: iron, stones, clump, such as the plant leaf, clean up till impurity content does not exceed 0.2%.

b. Crushing machine: Oilseeds are crushed into 6-8 pieces. In order to meet the requirements of crushing, the peanut is suitable for crushing with the moisture of 7% to 12%.

c. Softening Process: The purpose of softening is to adjust the moisture and temperature of oil, and make it soft.

d. Flaking process: Rolling raw material into flakes, and the purpose is to increae surface area, destroy the peanut cell tissue, shorten the way of oil out from cake.

e: Cooking process: Use steam cooking, inject direct steam and cook the flakes to meet the requirement of oil press.

f. Prepress: Press the flakes to leave about 16%-18% in the cake. The cake will go to extraction process.

g. Second oil press: Press the cake till the oil residue is about 5%.

Sunflower Oil Production Line Consumption in Operation:

1. Introduction

(1) Function: Edible oil extraction machine is an oil extractor through soaking or spraying pre-pressed cake by a certain organic solvent. The principle of this part is the different solubility of solvent.

(2) Use range: Edible oil solvent extraction fits for pre-press extraction of high oil- content materials and direct once time extraction of low-oil-content materials.

(3) Main parts: The edible oil extraction making series includes rotary extractor, toaster, 1st evaporator, 2nd evaporator, stripping tower, condenser, etc.

2. Main parts function

(1) Solvent pumps: continuously spray solvent to the rotary-typr extractor.

(2) Roary extractor: spray and soak the pre-pressed cake with solvent so that oil fats can be dissolved in solvent (form miscella). After processing, you can get wet meal and miscella (mixed oil).

(3) DTDC: used to separate the solvent from the wet meal.

(4) Miscella tank 1st: pump the miscella ( oil with solvent) into the miscella 1st, then add 10% saline water to it. The phospholipid and impurities in the miscella will react with the saline water, at last the reactant precipitate, reaching the goal of purifying.

(5) Miscella tank 2nd: the purified miscella will be pumped into it.

(6) Miscella stripping: it will remove the remaining solvent in miscella. And the solvent will be discharged to condenser for recycling.

(7) Condensers: used to cooling the solvent gas separated from the wet meal and miscella for recycling.

3. Main Process

(1) The material (for pretreatment) is sent to rotary extraction by the scraper conveyor. The material will extracted by the solvent or mix oil. After this step, we will get meal and mix oil.

(2) Meal is send to toaster. Through the toaster, the solvent in the meal will seperate from the meal.The solvent goes to condenser and is recycled to rotary extraction.

(3) After the mix oil from the rotary extraction enters into 1st evaporator and 2nd evaporator, most of the solvent in the mix oil is separated.

(4) The mix oil from 2nd evaporator goes to stripping tower and almost all the solvent is separated. From the stripping tower, we can get crude oil and solvent. The solvent is sent to condenser and is recycled to rotary extraction.

4. Advantages

(1) High oil yield, obvious economic benefit

(2) Less residual oil rate in the dry meal.

(3) Improving the quality of the meal.

(4) Low processing cost, high labor productivity.

Q: How to ask quotation?

A: Please note us what tpye of raw seeds , and how many tons of raw seeds you want to treat per day, then we will send you quotation as soon as we can.

Q: What's the difference between sunflower oil process and soybean oil process?
A: The biggest difference between these two is that the sunflower oil need dewaxing after refining.

Q: Why need extraction ?

A:If only pressed, oil residue inside cake is very high at lease 6%. But after extraction, the oil residue will be less than 1%, which greatly increases the oil yield.

Q: What chemical is used in oil extraction machine, and this chemical can be recovered?

A: Solvent n-hexane, most of this chemical can be recovered for recycling use.

Q: What will be happened if without good dewaxing?

A: Without good dewaxing, the final oil will be not so transparent as the oil with good dewaxing, especially in cold weather, the oil will easily become milky, or some solid inside.

Q: Do you offer oversea installation ,commissioning and training?
A: Yes. We will send experts to install, commission the plant and train workers.
