Screw oil press machine

Operating principle:

1.When oil press is on work, material enters the extruding chamber from the hopper and then moves forwards by the rotating pressing screw and is pressed.

2.Under hightemperature condition in the chamber, there is quite strong friction among press screw, chamber and the oil materials.

3.On the other hand, root diameter of the pressing screw carries larger from one end to the other.

4.Hence when rotating, the thread not only pushes particles moving forwards but also turns them outwards as well.

5.Meanwhile, particles adjacent the screw will rotate along with screw’s rotating, causing every particle inside the chamber to possess different speed.

6.Therefore, relative movement among particles creates neat which is necessary during manufacturing because of helping protein change property, damage colloid, increase plasticity, decrease oil’s elasticity, resulting in high oil.

Construction features:

6YL series spiral oil press is mainly composed of 7 major parts of screw axis, press cage, feed mechanism, cake yielding mechanism. transmission system, electric control part and vacuum filter part. All the parts are assembled on the frame and screwed as a whole.

Simple design , easy to operate , wide suitability , continuous operation, high productivity and high oil product ratio.

Advantage

Energy saving-----equal 40% lower electric power production, with the average small 6 KWH saving calculation, electricity production can save 30 yuan.

Saving of labor-----the same production can save Labour 60%, 1 to 2 people to organize production.

Widely used------ multi-usage, squeeze peanuts, sesame, rapeseed, soybean, canopy, flax ,more than 20 oil crops. Level 3 press, a squeeze net.

Oily pure----- vacuum filter residue and ensure the pure oil, conform to the health and quarantine standards.

Covers an small area----- oil mill only needs 10 to 20 square meters can satisfy the production need.

Brief introduction for the refining equipment:

Refining pot: Also named dephosphorization and deacidification tank,under 60-70℃, it occurs acid-base neutralization reaction with sodium hydroxide, After stirring by reduction box, it can decrease the acid value in oil and separate the impurity, phospholipid which will enter into soap stock. The oil can be refined further.

Bleaching pot: Also named bleaching, dewatering pot,it removes water from oil by vacuum. The bleaching earth is breathed into bleaching pot, after stirring,filtrated by filter and change the color of the oil.

Vertical blade filter machine: Equipped with vertical leaf filter to remove used bentonite from the oil, operating conveniently and continuously, low laboring tense, keeps environment well, keeps oil residence in deposable bleaching earth in low level.

Deodorization pot: It uses USU 304 stainless steel plate, under the vacuum condition of vacuum and high temperature (220-240℃, The deodorization system can remove fatty acid and other rare delicacy high efficiently. Meanwhile, the pot has the advantage of lowering steam consuming and avoid of the hydrolyzation of oil;

Process characteristics of 3T/D edible oil refining equipment.

Process description:

The whole process of intermittent refining:

Oil inlet→heating up→deacidification→dealkalizing→washing 2-3 times→dry dehydration. The total time is about 24 hours.

According to the difference of alkali thickness and oil temperature, the process of dealkalizing is divided into two types, one is low temperature with thick alkali (its initial temperature is 20 ~ 30 ℃, alkali thickness is 20 ~ 30 Be) and another one is high temperature with light alkali (its initial temperature is 75 ℃, alkali thickness is 10 to 16 Be). The former is generally applied and the latter is mainly used for crude oil which has low acid value, light clour and lustre, and less impurity.

I. Low temperature with thick alkali:

Adjust the oil temperature to 20~30℃, then put in 20~30Be alkali liquor in 5~10 minutes, and stir it about 20~60 minutes on condition of 60r/m. Increasing the temperature slowly when notice the separate of neatsoap after reacted, 1℃ per minute, when it reach 60℃, stop stiring, keep still and make soap feet settlement, it will takes nearly 6~8 hours, then let out the soapstock.

Ⅱ. High temperature light alkali operation:

Firstly,determine the alkali thickness in accordance with the alkali value of crude oil(according to the table below), account the alkali and water added in, when the alkali value is under 5, for each unit acid value, the total water added into per ton oil is 23 kg. When the alkali value is over 5, no more than 12% of the oil heavy, the exceeded alkali is only 0.005~0.002%.

When operating, first mix the crude oil, heat the temperature to be 70 ~ 75 ℃ diluted saline or phosphoric acid (concentration 90%) , when particles appear, add alkali, then continue to stir for 40 ~ 50 minutes and heat up to be 90 ~ 95 ℃ until soap grain obviously separated, and put into nigre after 2 ~ 3 hours' static.

Ⅲ. Washing:

After releasing the nigre, grease heated up to boom 90℃, then add in the hot water for washing, stirring. Water temperature should be about 5 ~ 10 ℃ higher than the oil temperature, for low water temperature tends to emulsification. After adding the water, continue to stir for 5 minutes, then rest 4 hours for precipitation, and release the soap water, wash 2 ~ 3 times depending on the oil quality and decide. Washed oil slowly heated up to 105℃, stirred dehydration for 1 hour, washed oil can also direct inhaled decoloring pot and vacuum drying 30 minutes.

Method of operate for descoloring

1 start the vacuum pump,vacuum degree ≥700mmHg

First, after washing of alkali refining inhaled decoloring pot, stirring, at the same time warming up to 90 ℃, and stir another 30 minutes, decrease moisture below 0.1%, then inhale a few decoloring agents "white earth, activated carbon >, the quantity depends on the oil color, generally, oil amount 2 ~ 4%, stirring 30 minutes, cooled to 70 ℃, use compressed air pressure to filter oil machines to separate the white earth and oil, then get decoloring oil.

Method of operate for deodorizating

l By vacuum pump oil bleaching inhaled deodorization pot, up to 755 mmHg in vacuum degree , begin distillation and deodorization timing;

l Deodorizating time : 4 Hours

l Deodorization temperature: 240℃/755mmHg~260℃/759mmHg

l Deodorization vacuum degree: above 755mmHg

l There is steam distillation during the whole timing process.

l After deodorization, shut off the direct steam in vacuum condition , close conduction oil,open the valve for cooling water.,until the oil temperature nearly 40~80 ℃,shut off the vacuum pump valve,make test of the oil sample,if it is passed inspection,packing and finish all the manufacturing of edible oil.

Characteristics

l Both short mixed and long mixed process are adapted in washing sector, which ensures washing effectiveness.

l Equipped with vertical leaf filter to remove used bentonite from the oil, operating conveniently and continuously, low laboring tense, keeps environment well, keeps oil residence in deposable bleaching earth in low level.

l Due to accurate stirring method, decreased the maximum distance between the oil of cooling facet so as to ensure the same temperature of crystal with same quality. Better guaranteed that in the process of crystallization, crystal will not cluster in a intense area.

l Flexible system, cooling curve can be easily altered by changing water temperature, thus the kinds of products can be changed easily.

l Stabilization of product quality.
