Cold press oil machine 5-600TPD

The production capacity of a Cold press oil machine 5-600TPD is between 1.5 and 10 kg of solid per m2 of filtering surface. For every filter press model, the chamber volume and the filtering surface depend on the number of Cooking oil making machine of complete set certificated by CE ISO BV plates.In practical terms pressing times are less then four hours. Filtration time depends on:cake thickness,sludge concentration,specific resistance,compressibility coefficient.One of the advantages of the Shandong Leader Machinery Co.,ltd. is that it can accept sludge with average filterability. Cold press oil machine 5-600TPD is always advantageous to optimally thicken sludge before filter press operations.When the Cooking oil making machine of complete set certificated by CE ISO BV has stopped, the filtrate circuits and central duct, which is still filled with liquid sludge, are purged by compressed air.Shandong Leader Machinery Co.,ltd. Washing of clothes should be carried out every 15-30 processing oprations. For mid- or large units this take place on press using water sprayers at very high pressure (80-100 bar).

1. Introduction

At present, soybean/sunflower/rice bran/corn germ/peanu/rapeseed/canola/cottonseed cooking oil production process have two kind 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 Here have some example of hot pressing and cold pressing method.

1.1.1 Process and methods of soybean seeds pressing.

There are two ways of pressing of special seeds: cold press and hot press.

(1) seeds cold press process: Soybean---Filtering---Press(suitable moisture)

(2) Hot press process: Soybean---Cleaning---Prepressing---Crude soybean oil---Filter---Twice pressing---Crude soybean 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.

1.1.2 Process and method of rapeseed press:

The rapeseed 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:Rapeseed/vegetable 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, during steaming add 2-3% water, will start milling after the seeds become brown and the temperature is 110-120°C.

1.1.3 The process and method of peanut kernel 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.

1.1.4 Character of seeds press/mill/expeller machine

1.2 The leaching(extraction) method is to use solvent naphtha (6#) after fully immerse oil meal raw material to high temperature (260 degrees) and extract the oil from seeds meal, after a "technology of six” (degreasing, degumming, dewatering, decoloring, deodorization, deacidification). The biggest characteristic is high oil yield and low production cost, the price is lower than squeezing method.

The extraction(LEACHING) method is widespread used in the market. Because of high oil yield and low production cost, the extraction(leaching) machine is hot sale in the worldwide.

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

The extraction method applies to vast oil seeds. Especially those high nutritional value but low oil yield seeds. Due to the advantage of leaching, this method is widely used in the cooking oil industrial. Approximately 90% of the oil in the world is using extraction method.

3. Crude cooking oil refining process

(1)Pump crude edible oil into refining tank and heat with conduction oil, and the temperature will reach about 70°C-80°C after one hour.

Add acid or alkali to separate according to the acid value. After one hour's processing and 4-6hours deposit, then convey soap stock to storage tank.

(2)Pump refined oil into decoloring tank. When it is up to 90-110°C after one hour's heating, add clay into tank for 20min's processing. Then separate clay and oil with filter.

(3)Put decolorizing oil into deodorization tank with vacuum pump. Heat and process with steam for odor removal. After filtering, you will get final oil product.

3. Raw material

soya cooking oil machine

After finish degumming process about Cold press oil machine 5-600TPD, at once add into lye carrying alkali refining deacid, lye concentration 16 ° Be ′, super alkali is 0.1to0.3% oil weight, after finish adding, continuous stirring 30min, when soap particles accumulated condensing, should reduce stirring speed, 30r/min avoid emulsion. After adding alkali, gradually rising temp to the end temp 65 ° C, see to that the rising temp speed should control at 1 degree per minute, not too fast. Shut off neutral pot drive part, theoil settled in the pot 6-8 hours, make oilseparate from soap.
