Edible cooking oil refinery plant | small coconut oil extraction machine

 1. Introduction of edible cooking oil refinery plant | small coconut oil extraction machine    

   At present, soybean/sunflower/rice bran/corn germ/peanut/rapeseed/canola/cottonseed cooking oil production process have two kinds of processing method: pressing and leaching(extraction).
Pressing method is by physical pressure and get oil directly from the oil seeds.
The whole process does not involve any chemical additives, to ensure product safety, health, pollution free. The expeller method is divided into cold pressing and hot pressing.
The difference of cold pressing and hot pressing is whether use high temperature process or not. Hot pressing using a high temperature,can improve the oil yield,but destroy nutrients;cold-pressed not to use high temperature, the oil is low, but the complete nutritional ingredients.

1.1 There are two ways of pressing of special seeds: cold press and hot press in Edible cooking oil refinery plant | small coconut oil extraction machine.

(1) seeds cold press process:

oil seeds--Filtering---Press(suitable moisture)

(2) Hot press process: Soybean/sunflower/rice bran/peanut ---Cleaning---Prepressing---Crude oil---Filter---Twice pressing---Crude oil after twice pressing---Filter

(3) Introduction of process: Will screen soybean and cleaning soybean first, then crushing soybean and add 7-8% of water to soften the seeds, 

send soybean to cooker, steam until about 115°C, then will press seeds.

1.2 Process and method of cooking oil press:

 The edible oil press have two ways of pressing, cold press and hot press. To improve the oil yield and oil quality, generally the hot press is used.

(1) Cold press:oil seeds---Screening---Squeezing---Steaming----Pressing, First, Screening the rapeseed and check the moisture content of rapeseed, if the rapeseed too dry, we need to add 2.5-3% water, later put the seeds into the expeller.

(2) Hot press: Rapeseed/vegetable seeds---Screening---Squeezing---Steaming----Pressing,Filter the rapeseed and remove the residue, and then enter the flaking machine for seeds flaking.After flaking,will go into the cooker for steaming and roasting,steaming add 2-3% water, will start milling after the seeds become brown and the temperature is 110-120°C.

1.3 The process and method of edible oil  pressing.

Hot press and cold press is suitable for peanut kernel, generally we use hot press. Hot pressing, the first crushing or flaking the peanut kernel, then placed in the steamer for 1.5-2 hours.When the  cake’s temperature arrives 120°C and water content is 3%, will start normal squeezing.
Peanut----Cleaning---First milling---filter----Press two times---Crude oil----Refinery---Press third times---Crude oil after pressing----Filter----Cake after pressing.  

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 edible oil solvent extraction line

 
The whole extraction 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 of edible oil extraction line:

 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 of edible oil extraction line:

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

 A.More than 40 years manufacturing experience.

B.26 technical engineers research on new efficient processing craft and instruct manufacturing and installation work.

C.76 technicians professional installation team with rich and mature installation and training experience.

D. CE & ISO9001&BV&TUV certificate.
