Zhengzhou Yuanyang Edible Oils Engineering & Technology Co., Ltd. is located in Yong He International Square, Zhengdong New Area, Henan Province. Our company was successfully reformed in 2005 with the registered capital of RMB10 million. Now we are a leading enterprise specialized in the technology design & research and engineering construction of oil preparation, oil refining & fractionation and biodiesel. After years of practice, we have won a high reputation and accumulated solid strength. We have undertaken more than 100 construction projects all over the country.

1. Introduction

Method of pretreatment and prepress line

Vegetable oil press production line includes two parts, one is pretreatment line, the other is oil seed press machine.

Pretreatment part is used for cleaning and adjusting texture of the materials , it can improve oil yield rate, reducing breakdown of the machines. General speaking, the pretreatment machines include Magnetic drum, Cleaning sieves, Sheller, Crusher, Flaking roll, Cooker, Softening pot , Puffing machine and so on. After pretreatment, the materials will be sent to oil expeller, then the crude oil got. Different materials have different pre-press methods. We usually collocate proper press line according to the customers' materials.

2. The difference of pressing and extraction(leaching):

Squeezing method due to the yield is low, so the raw material for squeezing must be seeds of high oil content, and itself is probably oil crops; Due only to squeeze at the same time, the residual oil in the cake is high, so the modern enterprise in order to save resources, the pursuit of efficiency of cases will be to squeeze the oil cake with leaching rule of oil again

3. Introduction of solvent extraction line

The whole oil extraction machine workshop is selected on the base of safety, reliable, energy-saving, less fault, easy maintenance, and long using life, adopting world advanced technology and equipment to achieve the best process effect.

Process flow:

The material(for pretreatment) is sent to the extractor by the airtight packing auger. The mateiral will be sprayed for extraction by the solvent(Hexance) or mixed oil after they fall into the extractor. The wet dreg(after dripping), falling into the conveyor and be sent to the evapo-separated machine. After steaming, baking and desolventizing, the dreg will be sent to the dreg storehouse. Mixed oil after extraction enters into the first and second long tube evaporator for seperating the steam and solvent, and then flow into the stripping tower for desorption the remaining solvent of crude oil. The extracted oil from the last process will be sent into the crude oil tank for refining plant. The solvent vapors from the extractor, evapo-separated machine, evaporator, stripper tower will be recycled in the cooling system. The solvent after cooling will be collected in the fresh solvent tank for reusing in the process.

Main equipment:

Rotocel extractor(loop type extractor), evapo-separated machine, Long tube evaporator, stripper tower, condenser, absorber, conveyor, sealing auger and so on.

5. Biodiesel production line

New tech for recycling used frying oil, waste cooking oil and oil seeds to get biodiesel, the esterification method is a hot and renewable technology of the world.

Biodiesel can be substitute of petroleum oil. The biodiesel is already widely applied as engine fuel in tractor, cars, sedans.

The advantages of bio diesel oil:

1. Green energy sources, environment friendly;

2. Sustainable energy sources, raw material is rich and steady;

3. Widely application and achieve the international standards.

4. It not belongs to dangerous cargo, easy to transport.

5. The supply of bio diesel is not controlled by OPEC, it’s benefit to the stability of international petroleum market.
