What is A WKIE LAB Thin Film Distillation

We now get to the core of the discussions. The thin-film distillation is basically a way of separating mixtures and separating substances through the process of distillation. It makes use of the low evaporation temperatures and low vacuum to tackle the chore. In the course of doing that, it greatly cuts down the residence time as well.

Its wipe film variant generates a thin film of liquid on the inner surface of the vertical evaporator by use of a wiper system. A typical thin-film evaporation goes through three critical steps. Here below, we delineate those steps and explain their suitability and roles in the entire process.

Step I: Fermentation

In its entirety, the process commences with fermentation. At this stage, the substances to be distilled are left to basically rot. In the process, the yeast breaks down the heavy molecules in small and manageable sizes. It is mainly followed in the case of working with organic particles. The step is unnecessary when dealing with inorganic compounds and substances.

Step II: Filtration

The second stage entails sieving out the coarse and insoluble particles from the solutions or substances. This is accomplished in several ways depending mainly on the volume of substances to be handled. A small sieve would do for limited volume whereas a larger one is handy for similarly larger volumes.

Step III: Distillation

At this stage, the resultant solution is introduced in a heating chamber. At the chamber, the solution is super-heated to the point of boiling.

The temperature is adjusted upwards slowly and steadily till it gets to around 190 degrees (F). It turns into a vapor that subsequently rises through a column into a condensation chamber.

Step IV: Condensation

As the vapor gets to the condensation chamber, it turns back into liquid form. The condenser has a thick wall that prevents the loss of heat. In regard to this, it facilitates the conversion from the vapor or gas to the liquid stage. The condenser is connected to a collection container using a special network of pipes.

Step V: Finishing

It is the step that precedes the packaging or bottling. The exact thing that happens at this stage depends mainly on the nature of the industry or installation wherein this process is employed. In food packaging, the preservatives are added. In a beer production setting, the flavoring is done, and so on.

Two Methods of Thin Film Distillation

As is the norm, with any other chemical or industrial process, thin-film distillation is also available in numerous shades and forms. That brings with it the need to identify and find out the most suitable pick for the job. But just what methods is the best? We start out by examining the two main kinds:

Short Path Distillation

This is a condensed version of the thin-film evaporator. In this sense, the condenser is paired with or attached to the center of the evaporator. As such, the distance between the condenser and the evaporation surface is severely shortened. This also eliminates the loss of pressure in the course of a distillation.

Thin-Film (Wiped Film) Distillation

In this sense, the condenser and the evaporator are separated into distinct components. They are nonetheless interconnected by a nozzle. Whereas it is a great method to tackle huge quantities of substances, it suffers greatly from the loss of pressure not to mention taking up too many mounting spaces.

Of these two, the short path distillation is undoubtedly better. It is truly energy-efficient and also tackles the task of distilling substances more fairly and effectively. Thus, you have it for your prioritization. Choose a thin film if you have a huge volume of substances to tackle.

The Features of WKIE LAB Thin Film Distillation

To be able to discharge its roles appropriately, the thin film distillation is packed with a host of unique features. It is certainly a great thing to know these features and what each stands for. This forms the basis of our explanations in the following sub-segment of our discussions:

Vertical Glass Cylinder

Its premier trait is the vertical glass cylinder. This is the one that holds the substances to be distilled firmly in place. The cylinder is paired with a heating medium that furnishes the heat necessary to trigger the distillation process. Though made of glass, the cylinder is super strong and resistant to damages.

Rotating Wiper Elements

The rotating wiper elements come in next. They are used to stir and spread the substances that are being distilled. In the course of doing that, they give rise to more uniform outcomes not to mention cutting down the overall time that would be taken to bring about the necessary outcomes.

Centrifugal Forces

To be able to have the rotating wipers perform their designated tasks well, they rely heavily on the centrifugal forces. These forces are generated by a motor and transmit the necessary force to the inner chambers of the container. They result in a more uniform distribution of the liquid film.

Cooling Thermostat

A cooling thermostat exists at the condensation chamber of the distillation system. Its role is to hasten the process of condensing the vapor into liquid form. In many models, this thermostat occupies the place that is right at the center of the glass evaporator to allow for easier impacts.

Adjustable Rotation Speed

Overall, the equipment gives you the leeway to adjust the rotating speed as per your expectations. Due to this capability, you will be able to accrue the distillation process in a manner that is wholly acceptable and convenient for you. That also cuts down the waiting time you may have to put in.

Excellent Controls

Throughout the system are some excellent controls. You will use these to regulate the various parameters of the distillation process. Among these parameters are the speed of the wiper motor, thermostat, power supply for the vacuum pump, prevailing temperature, and the vacuum itself. They jointly put ahead of the game of distillation.

Super-tough Structural Makeup

When all factors are put into consideration, the distillation system is made of super-tough structures. These include the hard-covering, PTFE slide coating, and Aluminum, to name but a few! They prevent unnecessary accidents from arising not to mention ensuring long-term use and applications. With them at your fingertips, you also spend less to maintain the system.

System Requirements

For this system to discharge its roles, it makes use of its constituent parts and components. Each part plays a unique role in the entire mix. Let us now break down these parts to know what each stands for and what role each plays in the entire system:

High Vacuum Pump

The high vacuum pump ranks first among the list of its many features. It plays the role of eliminating the molecules of the air and other gases from the distillation chamber. The purpose of this is to create an environment that allows the liquids to boil at extremely low pressures.

Chiller/Heater

It is the chiller or the heater that ups or lowers the temperature levels of the liquids inside the chamber. The chiller cools the liquid whereas the heater warms it. These two are the ones that regulate the pace of the distillation process, overall. You will find them at the base of the chamber.

Cold Trap Requirements

It is the cold trap that actually condenses the vapors into the liquid form. A cold trap comprises a thicker outer layer that prevents the ambient heat from interfering with the interior settings or environments. The cold trap occupies the center of the container’s chamber and is also the most outstanding.

Feed

The feed is an entry-point or pathway via which the fluids may be fed into the system. A feed is larger and spacious. It is attached to a narrow tube or pipe that leads to the container. Being the most significant part or component of the system, it is placed strategically for easier viewing and notice.

Entrainment Separator

In the course of the fluids evaporating, it is not uncommon for the mist to rise and mix with the vapors. This is not only confusing but also comprises the final outcomes considerably. The entrainment separators exist to set these two by-products apart from each other to give rise to purer outcomes.

Rotor

As part of the inner workings of the system, it has to streamline the flow of the gases into the cooing chamber. The part that performs this task of streamlining the gases is the rotor. It contains some radiating aerofoils that fan the gases and streamline their flows appropriately.

Mechanical Seal

A mechanical seal exists at the top of the container and plays the role of fastening the opening of the container to prevent any moisture or vapor from escaping. That goes a long way in preserving the interior contents from escaping out in the atmosphere unnecessarily.

Bottom Bearing

At the bottom of the container is a bearing. It fastens and loosens the bottom of the container to regulate the outflow of the concentrate in the collecting container. In many cases, it is fastened or loosened by hand. For this reason, it has to be greased and lubricated to facilitate the smoother motions.
