The working principle of double screw press:

The squeezing cage in two (upper and lower, horizontal lines) to screw axis in the squeezing chamber are mutually engaged, produced with continuous extrusionpressing cage constant driving force, the material in the germ oil squeezed out.Double stage structure design of high compression ratio, achieve radial pressurestrong, so that the oil may only press, the press is more thorough, residual oil ratethan single screw oil press oil rate lower, oil crops, oil yield is higher, suitable for anyoil crop cold and hot press.

Has the following 8 characteristics:

1, double screw press mechanism without smoothbore meshing screw technology,promote the squeezing chamber, the pressure is large, a squeezing clean, oil ratereaches above 93%, low dry cake residual oil rate.

The double helix axis 2, special design, theory compression ratio, oil in the squeezing chamber after 5 times of compression and expansion, achieving a strong press thick material layer and the thin layer combination.

3, wearing parts adopt carburizing steel manufacturing and the strict heat treatment,high strength, low temperature impact toughness, toughness, wear resistance, long service life.

4, double screw press low-temperature cold pressing technique to cancel the heatpressing, crushing, softening flaking, steaming and stir frying process, productionequipment, no environmental pollution, low power consumption, low manufacture cost.

5, the unique cake mechanism so that the screw axis centering support, when thecake thickness can be timely adjustment;

6, the pressing cage in a vertical plane triangulation, and two ends of the hingesupport. So the squeezing cage no slag accumulation, smooth oil discharge,convenient maintenance and repair;

7, low temperature pressing can retain the integrity of natural bioactive compounds in vegetable oil, such as unsaturated fatty acid, lecithin, vitamin, protein and trace elements. Squeeze the vegetable oil to keep its essence of natural color, smell andtaste of nature.

8, the cold pressed out of the strip pressing cake (meal) is a high value-added food,can be used for animal feed, fertilizer, fuel and protein extraction.‍

increase the oil rate

Rapeseed oil press machine yield is only thirty percent. The following skills, can use the oil rate twenty-five percent.

1 screen to sediment in the process of sediment will reduce oil, rapeseed oil yield.Should first screen to sediment before processing.

2 oil equipment general control the fire pan fried vegetables seed, are all cooked again when the opening of the rapeseed poured out, each time 1.5-2 kg rapeseed sticky burnt at the bottom of the pot. Therefore, when rapeseed Chaodao eight mature, will open the upper stove mouth, seal the lower air inlet, to control the fire. Specific operation method is: in the stove mouth on the walls of a movable groove, a movable plateembedded, need to fire, put the plate up, seal the mouth; when the need to slow fire,put the plate down, sealed air.‍

Press use common trouble causes and Solutions

1, the sieve cloth oil mill plantgo unilateral. When the examination, if it is not equal to screen surface horizontal level, should be adjusted so that the length of the screen body; if the emergence of torsion, adjustable eccentric shaft to the frame vertical. If it belongsto the stone screen surface oil go unilateral, can adjust the level of machine frame; if the air is not uniform, which can adjust the air regulating plate, so that the uniform airflow blows to the screen surface. If the screen net rate is low, should be replaced with new brush or brush length adjustment, adjust the tilt angle of the flat screen.

2, not to mention the material belt at. The main reason is, bucket elevator convey or lower oil mill accumulated too much, causing blockage, can open the conveyor lower door,clear the accumulation of oil.

3, on a steaming pot billet uneven. When the examination, if the dryer steam jet hole plug or rust, should clear the steam jet holes. If it is blank in the middle and lower thepaste pot, adjustable scraper and the distance; if the scraper twisted wear, replace the scraper; if it is blank cooking cooked unevenly, should adjust the limit switch,contactor and floating plate, so that the motor coordination.

4 roller does not rotate, overload. Exclusion method: start between rolls if there is oil,can loosen the roll adjusting bolts, remove roll oil; if they are feeding too much too fast, the feeding opening inserting plate closed; if the thickness of billet rolling out of uneven, nuts should be re adjust the roll gap, tighten the loose.‍

oil processing

Key oil press before start:

1, before starting the first gear box with 10 kg of oil.

2, available dry cake with proper water about 6-8%, stir evenly and feeding hopper pressing chamber, the press bore polish, begin feeding, dry cake should be slowly,not too fast, the discharge is normal, and appropriately increase the feeding quantity,repeated use of the cake moisture gradually reduced, the appropriate water. If the cake to feed too fast, too dry can make the pressing chamber pressure surge, caused the press bore blockage, causing the machine accident.

3, oil machine the squeezing chamber temperature is appropriate, there will be good pressing effect, therefore, should try to improve the pre pressing pressing chamber temperature. The method of blank can be fried hot, dry cake can also be used to heat water mix, slow feed mill, repeatedly, until the temperature rises, until the outer surface of hot date, then the normal press.‍

Preparation of crude oil

Pretreatment of oil

The main oil plant are herb oil and woody oil two. Herb oil soybean, peanut,cottonseed, rapeseed, sesame, sunflower seeds and so on; woody oil, tea seed oil,coconut, walnut, olive oil, tung oil etc.. Incidentally, the current national regulations by using genetically modified oil edible oil must be marked "genetically modified" wordson the packaging. Pretreatments including oil cleaning, drying, peeling, cashmere,crushing, softening, flaking and cooking process. The treated oil will enter the next link, used to produce crude oil.

Preparation of   crude oil production

Primary oil and edible vegetable oil press process, also is the crude oilproduction, there are two ways: press and solvent extraction. The press is a physical expression way, method of extracting oil from oil, oil production method which originated from the traditional workshop, but pressing now is industrialized operation.Leaching method is used in chemical engineering principle, a method is proposed foroil extraction from oil with food grade solvents. The development history of edible oil extraction technology from the world's point of view, oil extraction process is internationally recognized as the most advanced production technology. Leaching method is first developed and applied, in developed countries in recent years,leaching oil technology in oil production in  China in a wide range of applications

Edible oil which has several processing technology

At present the industrial production of edible oil only "press law" and "extraction" two.Pressing method is by physical oil press machinedirectly from the separated oil; extraction rules using organic solvent oil out of raw materials extraction, after the "six off" to remove the solvent, the national standard allows a limited solvent residue. Tell thepress method more natural theory, leaching yield higher. There is also a supercritical extraction method laboratory, using carbon dioxide extraction, this method is the most advantage, the industry is generally used only for extracting essence, essential oils,haven't seen in edible oil.

cold oil press, hot pressing are pressing method, oil crops, oil rate is high after heating (like fried peanuts more fragrant), so the heat pressing is common practice within the industry. In recent years, oil heating (or repeated heating) effects some demonized, therefore, only enterprises using cold pressing this concept, but the cold pressing is to control the temperature in a certain range, much impact on oil, or cold pressing, hot pressing in edible oil, nutrition security differences there is no difference, and exact description and remarkable, after all, the national standard of edible oil to squeeze method is an index.

Improvement measures of oil press

oil mill plant is by means of mechanical forces, extrude the oil out from the oil in the machine. Currently on the market of press is divided into multiple series, such as pressing refining one frying machine series, refining machine series, auxiliary equipment series, series of economic type oil press, oil filter, the large refining oil production line series, rapeseed screening impurity removing machine, hoisting machine, filling machine, portable centrifugal refining machine etc.. So we have in the use of press attention when what improvements?

First, we increased press series, technical expert group on the core components of vegetable oil plant technology research. The new process principle pressing chamber multistage propulsion, gradual pressure increase, series of press, the press from the original level three, level Four, level five, upgrade to level six, level seven, level eight press, the oil yield is improved by about 3%-5%, capacity benefit, economic efficiency.

Second, the need to increase the diameter and length, the press bore adjusting pitch,increasing the pressing chamber pressure point, further improve the production capacity

Third, also need to add the press bore oil guide slot, in order to avoid out of the grease to dip into the cake dry again, the oil guide groove is arranged in the device the squeezing chamber, the oil and cake rapid separation, improved the yield of oil.

Fourth, additional built-in infrared heating system, according to different requirements for temperature oil varieties, can be customized to meet the best pressing temperature, pressing the best conditions, so as to achieve the best efficiency of oil.
