LWS550 three phase centrifuge technology for avocado oil extraction

 

Avocado Oil Extraction
Avocado oil is generally only used in the cosmetics industry as the extraction process progresses. Now, avocado oil is also used as cold-pressed edible oil and in the chemical industry. Today, avocado oil has reached the same popularity as olive oil. And the market is growing. The extraction of avocado oil can be compared with the extraction of olive oil.

 

SEPARATION Decanters for Avocado Oil Extraction Process
Decanter Centrifuge provides the best solution for avocado oil production. The equipment can be used for the extraction and production of cold-pressed avocado oil. The avocado oil factory only needs to peel and clean the avocados and then use the centrifuge to separate the avocado pulp into pulp, oil, and water. Then, a separator is used to refine the oil phase and remove ultrafine impurities. The use of RS centrifuges for avocado oil extraction can ensure higher products and better quality.
Simultaneously, the centrifuge has been treated with wear resistance, can automatically adapt to the load level, and can operate continuously and stably.

Decanter centrifuges process characteristics
The separation process in a decanter centrifuge relies on a few process characteristics such as centrifugal force or G-force, sedimentation rate and separating factor, differential speed between the conveyor and bowl, and clarity of the liquid discharge.Decanter centrifuges require a centrifugal force for the separation of the solids from the liquid. This characteristic is dependent on the radius of the centrifuge and its angular rotational speed. A decanter centrifuge applies a force equivalent to several thousand G's, which reduces the settling time of the particles. It is also favored to maintain a large G-force, which will result in an improved separation.
The rate at which sedimentation occurs is an important characteristic of the decanter centrifuge separation process. The
sedimentation rate is influenced by the particle size, the shapes of the particles, their differential densities and the viscosity between the particles and the liquid. This process characteristic can be improved by utilizing flocculating agents. The sedimentation rate is also dependent on the separating factor of the decanter centrifuge, which is related to the centrifugal force.
The exterior bowl and the scroll conveyor rotate at different high speeds. This differential speed between the two is accountable for the sedimentation throughout the decanter centrifuge cylinder. A high differential speed results in a smaller residence time of the cake settlement, so it is necessary to keep the cake thickness to a minimum to avoid impairing the discharge quality.
Keeping the cake thickness to a minimum also aids in the improvement of the cake dewatering process. For this reason, it is necessary to obtain an optimal differential speed to balance the cake thickness and quality.
The characteristic above all affects the clarity of the liquid output which is dependent on the volumetric throughout rate, where a higher flow rate will result in a poor liquid clarity. Another characteristic that influences the clarity of the liquid output is the differential speed. A low differential speed results in a better clarity, therefore, aiding in the separation process. The G-Force also plays a role in the clarity of the liquid discharge. Higher G-force results in an increase in the separation of the solid particles from the liquid and yields a better clarity.

Extraction Flow Chart

 

1.Virgin olive oil:It is an oil product directly prepared from olive fruit by mechanical and physical methods (including cleaning, decantation, centrifugation or filtration, but excluding high-temperature heating and leaching with organic solvents). Without refining, it is rich in various original nutrients of olive fruit, with high nutritional quality.Among them, "extra virgin olive oil" can be said to be the "first oil" squeezed from olive fruit for the first time, with the highest nutritional quality.
2.Refined olive oil:It is the oil made from the fruit residue after the first press and several times of press. It can be eaten
only after refining. The processing technology of refined olive oil includes organic solvent leaching and high temperature
heating, which destroys or removes the original nutrients of olive fruit. Therefore, although the purity of refined olive oil is higher, the nutritional quality decreases. In short, virgin olive oil contains many "good impurities", such as phytosterols, squalene, chlorogenic acid, lignans, vitamins and minerals. Refined olive oil removes these "good impurities", and only fatty acids can be provided to consumers.
3.Mixed olive oil:It is a mixture of virgin olive oil and refined olive oil. Its nutritional quality is also between the two.
On the market, there are few products sold directly in the name of "refined olive oil", and refined olive oil is mostly used to
produce mixed olive oil.
4.Olive pomace oil:It is extracted from pressed fruit residue with organic solvent. Its quality is obviously lower than that of
real olive oil, but it can still be eaten after refining, and the price is usually much cheaper.
According to the requirements of GB 23347-2009, this olive pomace oil shall not be sold in the name of "olive oil".
5.Olive blend oil:Olive blend oil and pure olive oil are basically two different things. Olive blended oil is mostly prepared from olive fruit residue oil and other vegetable oils, such as rapeseed oil and palm oil. Its nutritional quality is far from that of olive oil, and its price is much lower.
In order to protect nutrition, when cooking olive oil, whether virgin or refined olive oil, you should avoid too high temperature. On the contrary, those olive blended oils are more suitable for cooking dishes at high temperature. Olive oil is also widely used in various cosmetics and skin care products, which can make the skin smooth and smooth and delay aging.

How it works

How does it work
The feed product is pumped into the decanter centrifuges through the inlet. Feed goes into a horizontal bowl, which rotates. The bowl has is composed of a cylindrical part and a conical part. The separation takes place in the cylindrical part of the bowl. The fast rotation generates centrifugal forces up to 4000 x g. Under these forces, the solid particles with higher density are collected and compacted on the wall of the bowl. A scroll (also screw or screw conveyor) rotates inside the bowl at a slightly different speed. This speed difference is called the differential speed. This way the scroll is transporting the settled particles along the cylindrical part of the bowl and up to the end conical part of the bowl. At the smallest end of the conical part of the bowl, the dewatered solids leave the bowl via discharge opening. The clarified liquid leaves through a paring disc (internal centripetal pump).
3-phase separation with a decanter

With a 3 phase decanter centrifuge, it is possible to separate 3 phases from each other in one process step only. For example, two liquids which cannot be mixed because of different densities (e.g. oil and water) are separated from a solids phase. The heavy liquid (water) collects in the middle between the oil and the solids layer. Thus the two liquids separated from each other can be drawn off from the decanter. The solids are transported via the scroll to the discharge openings as it happens also in 2-phase separation.
Typical applications of 3-phase separation are the production of edible oils such as olive oil, oil sludge processing, the
production of biodiesel etc.
Parameters and influencing factors of the separation

Feed, throughput and residence time

Through the feed, the separation medium to be processed can be input into the center of the infeed chamber of the scroll, where it is accelerated. The throughput will have an influence on the residence time.
Decanter Centrifuges Acceleration
The separation medium reaches its maximum speed in the decanter bowl, causing the solids to settle on the bowl inner diameter. A characteristic feature of the bowl is its cylindrical/conical shape.
Differential speed

There is a differential speed between the decanter bowl and the scroll, which is created by a gear unit on the industrial decanter centrifuges. The differential speed determines the solid content in the outfeed.
Filling volume / Weir discs or overflow weir
The clarified liquid flows to the cylindrical end of the bowl in the decanter centrifuge, from where it runs out through openings in the bowl cover. These openings contain precisely adjustable weir discs/weir plates by means of which the pond depth in the bowl can be set. The weir discs determine the filling volume of the bowl.

Advantages and limitations over competitive processes
Generally the decanter centrifuge has more advantages than disadvantages; however, there are some limitations when compared to other processes.
Decanter Centrifuges Advantages:
* Decanter centrifuges have a clean appearance and have little to no odor problems.
* Not only is the device easy to install and fast at starting up and shutting down but also only requires a small area for
operation compared to other competitive processes.
* The decanter centrifuge is versatile as different lengths of the cylindrical bowl section and the cone angle can be selected for different applications. Also, the system can be pre-programmed with various design curves to predict the sludge type, while some competitive processes, such as a belt filter press, cannot change the belt type to operate for different sludge types. Its versatility allows the machine to have various functions such as operating for thickening or dewatering.
* The machine can operate with a higher throughput capacity than smaller machines. This also reduces the number of units required.
* The device is simple to optimize and operate as it has few major variables and reliable feedback information.
* The decanter centrifuge has reduced labor costs compared to other processes, as it requires low continuous maintenance and operator attention.
* Compared to some competitive process such as the belt filter process, the decanter centrifuge has more process flexibility and higher levels of performance.

Decanter Centrifuges Limitations:
* The decanter centrifuges cannot separate biological solids with very small density differences, such as cells and viruses. A competitive process that is capable of separating these difficult-to-separate solids is the tubular-bowl centrifuge.
* The machine can be very noisy and can cause vibration.
* The device has a high-energy consumption due to high G-forces.
* The decanter centrifuge has high equipment capital costs. Hard surfacing and abrasion protection materials are required for the scroll to reduce wear and therefore reduce the maintenance of the scroll wear.
