falling film evaporator in the cannabis industry

  During the process of processing cannabis, there is one step using falling film evaporator. Falling film evaporator is in charge of separating substances from the mixture. In cannabis-processing process, falling film evaporator is to get ethanol evaporated. In this way, we can get purer cbd, and ethanol can also be recycled.

falling film evaporator pharmaceutical

  Falling film evaporator is also used in pharmaceutical field. People use falling film evaporator to extract or concentrate some medical substances, in order to get purer or thicker substances. Besides pharmaceutical field, falling film evaporator is also used in chemical engineering, food-making and other fields.

falling film evaporator cleaning

  Falling film evaporator has automatic cleaning system, which means it can clean the whole equipment by itself. Cleaning equipment is very essential for the working equipment, so cleaning the falling film evaporator regularly is very essential. An automatic cleaning system is very convenient for users, which it can save so much energy and time for users.

falling film evaporator separator

  In falling film evaporator equipment, separator is an essential part of this equipment. Separator is the device that separates different substances. During the working process of falling film evaporator, some substances are concentrated, in the meantime some substances are extracted. So separator can separate these different substances.

falling film evaporator sugar industry

  Falling film evaporator has been used in sugar industry for a long time. During the working process, sugar juice is distributed on the vertical tubes and flows into the bottom in films. Then the sugar juice is heated into gas by heating chamber. And then the gas-phase sugar juice will be condensed and collected .

falling film evaporator heat transfer coefficient viscous

  In falling film evaporator equipment, heat transfer coefficient can be influenced by feed concentration and pressure. Scientists specially have some experiments to prove that. In these experiments, scientists used control variate method to design the operating processes. And it turns out that heat transfer coefficient has something to do with fluid properties, geometric parameters and flow rate.

climbing and falling film evaporator uses

  Climbing film evaporator and falling film evaporator are both efficient evaporators, which are widely used in chemical field, industrial field, food-making field and other fields. People use these two evaporators to separate, concentrate substances from mixtures. For example, the extraction of hemp; the concentration of sugar.

falling film evaporator advantages and disadvantages

  Falling film evaporator has some advantages and disadvantages. For example, the advantages are: dividing materials into thin films is beneficial for the evaporation of materials, which increases the evaporating efficiency; higher efficiency than the traditional evaporator. The disadvantages are: it is not suited for salting or scaling materials; the headroom requirements of falling film evaporator is really high.

application of falling film evaporator

  There are so many applications of falling film evaporator, because falling film evaporator is used in industrial factories,chemical process industry, food-making field and other fields. For example, in industrial factories, people always use falling film evaporator to separate ethanol from the mixture to get a pure hemp during the extraction of hemp. Whats more, there are other separation examples of falling film evaporator.

falling film evaporator principle

  The working principle of falling film evaporator is that, putting the materials into the falling film evaporator top, which will be divided into thin films then. The film-shaped materials are easy to be evaporated. Then the evaporated gas -phase substances will be separated and then condensed into liquid-phase, which is convenient to be collected. Then users will collect the liquid-phase substances.

Parts of a falling film evaporator

  In falling film evaporator equipment, there are several essential parts in it, for example, falling film evaporator heat exchanger, separator, preheater, condenser, condensate tank, circulation pump and other components.

Ethanol

ethanol evaporation temperature

  The temperature that ethanol gets evaporated is the boiling point of ethanol. There are two ways to calculate the boiling point of ethanol, which are Fahrenheit and Celsius. In Fahrenheit, the ethanol evaporation temperature is 212 degrees Fahrenheit. In the meanwhile, in Celsius, the ethanol evaporation temperature is 78 degrees Celsius. The boiling point is much higher than water’s boiling point.

ethanol extractors

  Ethanol is widely used in the extraction and separation of substances. It is always used to extract substances out of the mixtures as the washing solvent. Ethanol is used as washing solvent in so many ethanol extractors, for example, falling film evaporator, industrial centrifuge, molecular distillation, closed loo extractor and other extractors.

falling film evaporator for ethanol recovery

  As we all know, falling film evaporator is a separation equipment for concentrating or separating substances, especially heat sensitive substances. What’s more, ethanol also can be made by falling film evaporator. Falling film evaporator can achieve the recovery of ethanol by recycling ethanol after extracting sample materials.

does ethanol evaporate

  Ethanol has a quite low boiling point, which means ethanol is very easy to be evaporated. The boiling point of ethanol is lower than water, which is about 78 degree. So that means when ethanol is in the environment that the temperature is under 78 degree, ethanol can get evaporated. Therefore, ethanol does evaporated and the evaporation can happen very easily.

  
FAQ

what is a falling film evaporator

  Falling film evaporator is a industrial separation equipment, which is used to separate substances, especially for the heat sensitive components. There are two different types of falling film evaporator, which are vertical falling film evaporator and horizontal falling film evaporator. These two falling film evaporators have different systems, so they are used differently on the materials.

What is a falling film evaporator used for?

  Falling film evaporator is widely used in many fields, including industrial factory, chemical engineering, petroleum and other fields. Falling film evaporator has a high efficiency on the separation of substances, so it is used on milk, glucose, starch, pharmaceutical, chemical, biological engineering, environmental engineering, waste liquid recovery and so on.

How does a falling film evaporator work?

  In falling film evaporator equipment, sample materials will be added from the top of falling film evaporator. Then the materials will be divided into thin films, in order to get heated and evaporated more easily. The heating temperature will be set on the boiling point of substance’s boiling point, which is about to get evaporated. After evaporating the substance, the mixture and substance will be separated.

How falling film evaporator extracts cbd

  Falling film evaporator is suitable for heat-sensitive substances, so using falling film evaporator to extract cbd is a right choice. During the extracting process , hemp is added to the upper tube of the heating chamber, and evenly distributed into the heat exchange tubes through the liquid distribution and film forming device. Under the action of gravity and vacuum induction and airflow, it flows into the uniform film from top to bottom. During the flow, the cannabis is heated and vaporized by the shell-side heating medium. The generated steam and the liquid phase enter the separation chamber of the evaporator. The vapor-liquid is sufficiently separated, and the steam enters the condenser for condensation (single-effect operation) or into the next evaporation. The device acts as a heating medium to achieve multi-effect operation, and the liquid phase is discharged from the separation chamber.
