What Is The Difference Between Solvent Extraction And Solvent Distillation?

The main difference between solvent extraction and solvent distillation is that the latter is able to purify both liquid and solid phase substances.

Solvent distillation, on the other hand, is only able to purify substances that are in a liquid mixture.

Solvent distillation is mostly used in the petroleum and solvent industry. Solvent extraction is commonly used in industries like fragrances, food products, pharmaceuticals, and essential oils.

The techniques which are used in solvent distillation include vacuum, simple, zone, steam, fractional, air-sensitive vacuum, and short path distillation.

Insolvent extraction processes the most common types include liquid-liquid extraction and solid-liquid extraction.

Which Are the Solvent Types Used in Solvent Extraction Machine?

The solvent types used in solvent extraction include:

  • ethyl acetate
  • diethyl ether
  • ethyl acetate
  • chloroform

What Are the Properties Of The Best Solvent To Use In A Solvent Extraction Equipment?

The perfect solvent for use in solvent extraction equipment should possess the following properties:

  • It should be miscible with the liquid supposed to be extracted.
  • Be immiscible with the other components of the mixture or should react with the solute.
  • Have a low boiling point that is below the solute’s melting point to evaporate easily after collection.
  • Possess a favourable temperature coefficient
  • Not toxic and not flammable because it may harm the instruments used for extraction
  • Volatile: the solvent should be very volatile in a way that it can be removed with ease from the extracted material through distillation.
  • Should not dissolve impurities.
  • To help in easier separation, the compound’s density should be different from that of the required component.

Why Is Hexane the Common Solvent To Use In Solvent Extraction Equipment?

Which Are The Main Stages Of Extraction Process In Solvent Extraction Machine?

The extraction process in solvent extraction machine is categorised into the following stages:

  1. Preparation Of Raw Material: materials should be well prepared to ensure that the solvent must meet all of the material’s oil-bearing cells.

    Smaller material sizes allow for perfect solvent penetration to oil-bearing cells although they should not be too fine to inhibit the process.

  2. Extraction Process: the material which is prepared gets into the extractor via the rotary air seal.

    During movement, the extractor’s bed is continuously washed at several points using miscella of decreasing concentration and finally a fresh solvent.

  3. Desolventization Of Extracted Material: after a wash by fresh solvent the material is removed from the band conveyor to a chain conveyor conveying it to the disolventiser.

    The material is heated to 100°C using jacketed steam and then discharged via an airtight seal to the pneumatic conveyor then to the bagging section.

  4. Distillation Of Miscella
  5. Recovery Of the Solvent by Absorption: in the dissolventiser, the solvent which is absorbed is evaporated into vapours.
  6. Meal finishing and bagging.

What Are the Extraction Techniques Employed in Solvent Extractor Machines?

The techniques employed in solvent extraction include:

  • Batch Extraction: it is used with small-scale chemical industries and the process is conducted using a separator funnel.
  • Continuous Extraction: it is used on components that require multi-stage extraction. That is, they need materials to be separated at every stage.
  • Counter-current Extraction: it is well performed by using a disc disintegrator that is toothed to produce fine slurry. In the counter-current extraction method, the material which is to be extracted moves in one direction and the solvent in the other direction.
  • Phenoxy process: removes phenol from the effluent of catalytic cracking in petroleum refinery.
  • Super critical fluid extraction technique
  • pressurized liquid extraction.
  • microwave assisted extraction
  • Maceration: Involves extraction of thermolabile components
  • Percolation: continuous process in which the saturated solvent is constantly being replaced by fresh solvent.
  • Decoction: The extract from decoction contains a large number of water-soluble impurities.
  • Reflux extraction: requires less extraction time and solvent.
  • Soxhlet extraction
  • Supercritical fluid extraction (SFE)
  • Ultrasound assisted extraction (UAE)
  • Microwave assisted extraction (MAE)
  • Pulsed electric field (PEF) extraction

Which Are the Products That You Can Process with Solvent Extraction Equipment?

Some of the products you can process with solvent extraction equipment include:

  • Soya bean seeds
  • Cotton seeds
  • Sunflower seeds
  • Corn or maize
  • Rice bran
  • Peanuts or groundnuts
  • Castor seeds
  • Palm kernel
  • copra
  • Canola or rapeseeds

Can You Recycle the Solvent During The Operation Of The Solvent Extraction Machine?

Yes, you can recycle the solvent during the operation of the solvent extraction machine as this makes the process economical.

To recycle the solvent, the solute requires stripping from the solvent and then the solvent should be recycled back into the process.

This ensures indefinite recycling of the solvent until it degrades due to radiolytic degradation or hydrolysis of the acid.

Also, it may degrade if its composition changes because of solubility in the aqueous phase.

What Are The Benefits Of Integrating A Solvent Recycling System With Solvent Extraction Equipment?

Benefits of Integrating a solvent recycling system with solvent extraction equipment include:

  • Reduces the solvent’s consumption
  • Cuts down the production costs
  • Ensures production safety
  • Improves products’ quality

How Does Bed Type Affect The Performance Of Solvent Extractors?

The type of bed affects the performance of the solvent extractor in various ways some of which include:

  • The shallow bed design ensures the solvent is distributed evenly and there is consistent percolation in the material’s bed.
  • Due to the shallow bed design, the material is not well compacted. This causes the percolation rate to remain high despite the quality of the product prepared.
  • The shallow bed type also tends to eliminate dry spot formation because there are no internal vertical dividers or cells.
  • Deep extractors tend to suffer from compression of materials, poor percolation, slow drainage, long extraction times, and high solvent carry-over.
  • Uniformity is not available whit the deep extractor bed type and thus may produce varying content of solvent and different densities.
  • Deep bed extractors tend to also damage fragile materials
  • Slow drainage may also be caused by deep bed extractors. This tends to cause the high solvent to carry over to plant steam consumption.

Which Are The Main Parameters To Control When Using Solvent Extraction Equipment?

Some of the main parameters you should control include the following:

Temperature

Sufficient temperature must be present at the solvent extractor equipment inlet for the entire equipment to operate near or at solvent’s boiling point.

The extraction process entails mixing, dissolving, and flow processes and it functions faster and better when hot.

Solvent

The ratio of solvents to solids entering the solvent extractor should pass through an adequate number of effective wash stages.

The stages should be concurrent to the declining oil concentration until it reaches the final solvent pure wash.

Time

Ensure there is sufficient time for dissolving and for the flow process to take place.

This is best utilized if the bed is kept at full depth to ensure maximum solvent extraction equipment volume and depth.

Contact

It needs correctly prepared material and extractor suited for most effective drainage and washing for several material ranges even those of low quality. A shallow flake bed reduces the time at each stage in the process and even in the final drainage.

What Is The Meaning Of Miscella In Solvent Extractor?

Miscella refers to a solution of solvent and oil that flows evenly onto the bed through weirs or distributors. It is formed once the raw material has been treated by use of hexane, then the oil is recovered through distillation.

How Do Batch Solvent Extractor And Continuous Solvent Extractor Compare?

Here is all you need to know about these techniques:

Batch Solvent Extraction Machine

It entails extracting the solute from a single immiscible layer into the other by shaking the two layers until equilibrium is got.

Once this is done, the layers are allowed to settle then sampling is done.

Batch extraction is mostly used on small scale like in chemical laboratories. The common apparatus used in carrying out batch extraction is a separatory funnel.

Continuous Solvent Extractor

It is used primarily for fractional purposes, and it is achieved through difference in density between the fluids which are in contact.

In vertical columns, the denser phase enters the top and exhibits a downward flow.

The phase that has a less density flows upwards and gets in at the bottom.

The suitable method to select will generally depend on the solute’s value of the distribution ratio and separation factors of the material interfering.

Continuous Solvent Extraction Machine

Continuous Solvent Extraction Machine

What Is the Output Of Your Solvent Extraction Equipment?

Our solvent extraction equipment recovers averagely the entire oil and only leaves a very small percentage of residual oil in the raw material.

In case of use of mechanical pressing, the remaining oil in the oil cake maybe about six to fourteen percent.

The solvent extraction equipment can be directly applied to ant materials of low oil content.

Our solvent extraction equipment will make sure that you recover a high percentage of oil and can be used to extract pre-pressed oil cakes.

Do You Manufacture Mini Solvent Extraction Plant Machinery?

Yes, we do manufacture mini solvent plant machinery once you confirm the capacity that you need.  We will ensure that it is designed to suit your specifications.

Is Solvent Extraction Equipment Environmentally Friendly?
