What Are The Components Of A Tea Extraction Machine Configuration?

Several parts make up the tea extraction machine functional.

These include:

Extraction Tank

This is the part responsible for extracting the final product from the raw material.

Concentration Tank

Here, the machine will concentrate the extract that has low solid content. It does this by applying a low-temperature concentration vacuum that maintains low temperature and degree here.

Also, it lowers the water’s boiling point thereby making it evaporate rapidly.

Oil-Water Separator

This component will make sure you achieve the best recycling process in the tea extraction machine.

Pipeline Sight Glass

This component allows you to see the extraction process such as the direction of flow, average flow rate, and flow condition.

Safety Valve

It is the part that will release materials automatically when the temperature and pressure levels exceed the limits. They will therefore maintain safety during the operation of both you and the machine.

Control Panel

This is the part containing a PLC and an HMI. It assists you to input the extraction parameters and monitor the process.

Temperature Controller

This is the part that makes sure you achieve an accurate temperature in the whole extraction process. It has buttons that you can manually set the correct temperature for the production process.

Water Ring Pump

This impeller is star-shaped and will eccentrically rotate in a housing that contains liquid. Also, the vanes here will dip in liquids at different depths and as it revolves, forms gas-filled cavities.

The cavities will form between the vanes and the liquid. Water ring pumps are good for pumping gas since the gas-filled cavities will increase or decrease as it revolves.

Heat Exchangers

It is responsible for providing heat to the materials thereby improving the extraction and concentration processes. For instance, a jacketed heating technique ensures that you achieve uniform heating.

How Does A Tea Extraction Machine Work?

Here is how this machine operates:

Step One: Injecting An Aqueous Solvent

This is the part where you introduce a liquid solvent to the extraction tank. It will then flow to the product you are extracting through a safety hose and conduct the extraction.

Besides, how long the process takes and the pressure here will depend on the type of aqueous solvent of choice. Also, the soaking time is the duration the aqueous solvent is in contact with the material you are extracting.

Step Two: Extraction Process

The extract from the material will collect in the extraction chamber. Also, the machine applies pressure which pushes the solution automatically through silkscreens.

It will then go to the separator and finally settle in the collection chamber.

Step three: Collection

In this stage, the machine evenly applies heat to the solution and the solvent will start to evaporate. This process of evaporation increases pressure and makes it go out of this chamber via valves. Once this happens, the extract remains behind.

Step Four: Recovery Of Solvent

Once the solvent settles in the vessel after evaporation, recovery pumps withdraw it via connectors.

Applying heat will make the process move quickly.

Also, a desiccant filter cleans the extract as it heads to the recovery pump from expansion filters. Pulses drain the solvent, fumes settle, and they the machine discharges it to the operating tank for recycling purposes.

Industrial Tea Extraction Machine

Which Are The Common Extraction Techniques Used In Tea Extraction Machine?

These include:

Conventional Solvent Extraction

This is an old, time-consuming, labor-intensive, solvent-consuming process that is not very efficient. Besides, it has a low yield efficiency.

Some of the main phytochemical recovery applications in this method are hydro-distillation, maceration, reflux, and soxhlet. This process offers better yield when you use fresh leaves rather than mature leaves.

Also, refluxing has a better result than maceration. The efficiency of this method relies on the extraction solvent depending on polarity, and suitable heat treatments.

Besides, this method can degrade thermo-sensitive ingredients and have an incomplete extraction.

Some limitations include using large amounts of substrates, solvents, and sorbents. This means you have a high production cost and disposal of these products is an environmental hazard.

Ultrasound Assisted Extraction [UAE]

This process entails propagating ultrasound pressure waves in the medium then forming cavitation bubbles. Since bubbles cannot expand over a specific limit, they will implode and form micro-turbulence.

This will disrupt the cell membrane and enhance its permeability thereby increasing solvent dissolution of the material. Besides, an ultrasonic bath is less efficient than ultrasound probes.

This method is suitable for tea extraction because it is efficient at low temperatures. Extraction at high temperatures can degrade the extract and increase pectin and protein extraction. This will interfere with the quality of the tea by forming cream.

Microwave Assisted Extraction [MAE]

When the product absorbs microwave energy, it changes to thermal energy through dipole rotation and ionic conduction.

As the microwave energy passes through the substance, there is a rapid increase in temperature.

This will make the internal water vaporize and disrupt the cell and plasma of the biomass. There will be an increase in permeability and this will enhance the dissolution by increasing the temperature.

The only limitation in this process is high-temperature levels which may cause degradation.

Factors that will affect the yield in this method are:

1. Power of microwave
2. Frequency of microwave
3. Number and duration of microwave radiation
4. Size of particle and moisture content of the sample plant
5. Concentration and the type of the solvent
6. Solid-liquid ratio
7. Pressure and temperature of the extraction process

High Pressure Processing [HPP]

This is a low-temperature technique that retains freshness and has microorganism inactivation. To increase the solubility and permeability of the extract, this method will apply pressure.

Some limitations of this process are chances of protein degradation and structural alterations of some food components. This process will increase the longevity of a product.

The types of HPP you can use for tea extraction are:

1. Ultrahigh pressure extraction [UPE]
2. High hydrostatic pressure extraction [HHPE]

Supercritical Fluid Extraction [SFE]

This process needs fewer new environmentally friendly technologies especially for the extraction of tea catechin.

Some main issues with this technique are less time consumption, higher selectivity, and avoiding organic solvents.

Fluid changes to a supercritical fluid that has higher diffusivity and low viscosity than liquids. This happens when the temperature and pressure go beyond a specific level.

The industrial application will make use of carbon dioxide to achieve this as it is abundant, recyclable, and has a low critical point.

To extract tea fluidizes carbon dioxide through high pressure in adsorption columns helps with the extraction. This process is suitable for decaffeination techniques and its limitation is the loss of tea catechins.

What Determines The Filtration Accuracy Of The Filter Device In Tea Extraction Machine?

In-built double filter meshes will determine the filtration accuracy of this machine.

Examples of the available meshes are:

• 100 mesh
• 200 mesh
• 400 mesh

What Is The Role Of Concentration Tank Of Tea Extraction Machine?

The main purpose of this tank is to concentrate the extract from the plant material as it has low solid content.

It will make use of a low-temperature vacuum concentration and heat exchangers.

It will also protect all the active ingredients and the material properties of the extract.

The concentration tank will vaporize the water content from the liquid leading to the formation of a concentrate.

Does Tea Extraction Machine Retain The Tea Flavor In The Final Product?

Yes, the machine has mechanisms that will minimize the loss of flavor during the production process. It will capture the flavor of the raw materials before the machine subjects it to high temperatures.

The machine captures the flavor notes of the tea product at the peak early in the extraction process.

After that, it will add this flavor back to the concentrate at the end of the tea extraction process.

Can You Process All Types Of Tea Using Tea Extraction Machine?

Yes, the machine can process a variety of tea such as black tea, green tea, and oolong with no equipment change.

Why Is Heating Vital In The Vacuum Concentration Tank Of Tea Extraction Machine?

This is because it increases the quality of the concentrate by a large percentage when you compare it to not heating.

Also, heating will shorten the time it takes for the extract to concentrate.

Vacuum Low-Temperature Vacuum Concentration Equipment

Is It Possible To Control Product Quality In Tea Extraction Machine To Meet Expectations Of Target Market?

Yes, you can adjust the operating parameters to control the concentration and aroma profile of the product.

As a start, you can change the aroma profile through several production parameters in the tea extraction machine.

This makes it possible for you to process a product that suits the expectations of the target market.
