Rotocel Extractor

1. Adopt stainless steel fixed grid plate and increase the horizontal grid plates, which can prevent the strong miscella from flowing back to the blanking case, so as to ensure good extraction effect;

2. The rotocel extractor is driven by rack, with unique rotor of balanced design, low rotating speed, low power, smooth operation, no noise and quite low maintenance cost;

3. The feeding system can adjust the rotating speed of airlock and main engine according to the feeding quantity and maintain a certain material level, which is beneficial to the micro negative pressure inside the extractor and reduce the solvent leakage.

4. The advanced miscella circulation process is designed to reduce the fresh solvent inputs, reduce the residual oil in meal, improve the miscella concentration and save energy by reducing the evaporation capacity.

5. The high material layer of the extractor helps to form immersion extraction, reduce the meal quality in miscella, improve the quality of crude oil and reduce the evaporation system scaling.

6. Specially suitable for the extraction of various pre-pressed meals.

Main Paramaters

1.Deacidification
Sodium hydroxide antagonize free fatty acids,and subside phospholipids,to remove the insoluble impurities,then after the separation of soapstock, neutral oil was washed in soft water,last drying in vacuum.
2.Bleaching
Used to remove off pigments, bleaching oils and grease dehydrate

3.Deodorization
Using high temperature and high vacuum steam stripping method deodorization temperature commonly 180, vacuum degree 9.3 104 Pa can achieve ideal results
4.Dewaxing
Dewaxing can ensure the colour of the oil to be clear bright at room temperature and frozen temperature. to reduce the oil in the wax content to 10 parts per million to get crystal clear 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 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.
