If you are unaware of the product, then you are at the right place.

In this write-up, you will come to know about the dehumidifying dryer.

What do You know about Dehumidifying dryers?

The dehumidifying dryer is equipment that is framed in such a way to do away with humidity present in plastic material prior to processing.

Air is passed across the desiccant bed for best dry. Air is again heated at a specific temperature, which is supplied to a drying hopper containing the material to be dried.

The desiccant holds the moisture for a short period before drying out, and the current of air is robotically redirected to another desiccant bed to continue the drying process.

The initial desiccant bed is regenerated in this period to eradicate the moisture again, put to cool, and then becomes ready to sucks the moisture.

The dehumidifying dryer comes in 2 in 1 and 3 in 1 range which is assembled as a single unit.

What Is the Purpose of Dehumidifying Dryer?

Have you ever encountered silver marks, black spots, bubbles, poor transparency, or blisters on plastic material? This all occurs in PET due to ineffective drying.

Moisture saturation occurs in the resin due to contact with the surrounding during storage or transmission of material.

Dehumidifying dryer supplies dry air to the dew point of -40⁰C, which conclusively lessen the humidity of PET resins and stabilize its’ nature.

The dehumidifying dryer is a need to remove the moisture for a better quality of plastic. The moisture must be less than 0.002% before the dehumidification starts.

Dehumidifying dryer results in an increase of strength and uplifts the speed of the drying process.

Which Steps Are Required to Clean PET With Dehumidifying Dryer?

Certain steps are needed by dehumidifying dryer for cleaning of PET resins from the material. These are mentioned as:

Airflow

It is the 4th important parameter in the process of drying.

This medium transfers the dehumidifying low dew-point air from the dehumidifying dryer to plastic pellets.

When the airflow is not optimum, then the drying process takes time. However, intense airflow thermally deteriorates the plastic material.

In this way, airflow must be done with some speed in the dehumidifying dryer.

Drying Temperature

It is the main feature when considering the drying process. Elevated temperature loses the tensile strength of the material and results in water leakage.

The drying process for PET is done at a possible given temperature.

Saturated Air Temperature

This temperature depicts the humidity content in the plastic material. When the process is done in dehumidified air, then the air sucks all the moisture from the material due to increased absorbing capacity.

Time of Drying

PET material needs time for proper dry. When it is given heat at a low dew-point, then time must be provided for the perfect removal of water droplets from the product.

Explain the Characteristics of Dehumidification Dryer?

The characteristics of the dehumidifying dryer are as follow:

  • Possess PID control microprocessor
  • It consists of blowers with high pressure
  • Dew point gained is -40⁰C

  • It consists of converse alarms

What Are Various Types of Dehumidifier?

A dehumidifier is a device or equipment that is used to remove the moisture from the materials. Let’s take an insight into various types of the dehumidifier.

  • Refrigerant type
  • Desiccant type

Refrigerant type

This kind of dehumidifier is helpful to remove the humidity from the surroundings. It operates on the principle of the Vapor Compression Cycle.

This type of dehumidifier cools the air below the dew point. Humidity is removed due to the condensation method.

The dried-up air is again heated at possible room temperature and supplied to the surrounding.

Desiccant type

This kind of dehumidifier sucks humidity from the surrounding into the plastic or desiccant materials.

The air which needs to be dried is passed via the rotor in single air pressure. The rotor brings the humid desiccant back to the reactivation air pressure to provide it heat.

The moisture is sucked out of the desiccant material in the form of vapors. Hot air is ducted outside.

In this way, a separate air stream moves on a different path to eradicate any dirt out of the processed air, and the dried air is circulated back to the original point.

What Is the Difference between Plastic Dehumidifying Dryer and an Ordinary dryer?

The plastic dehumidifying dryer and an ordinary dryer are differentiated in such ways:

The plastic dehumidifying dryer is essential in lifting and dehydrating plastics electronically after they are pressed and washed.

The dehydration rate reached is 90% which improves the quality of cleaning and saves energy intake.

Ordinary dryers make use of electric heating and warm air to dry the materials present in the area at elevated temperatures to evaporate water.

In ordinary dryers, incoming air is heated as it contains a high rate of moisture, so the material is difficult to dry.

Working Principle of Dehumidifier Dryer

Clean and compressed plastic material is added to the feeding system of the machine. The motor is set to motion. The motor firstly drives the fan. When the first fan rotates with speed, a large amount of pressurized air is generated with the help of it.

The generated air slowly gets rid of all ductile material and blows into the spiral tube. Shut-up valves are opened, and the dry power falls into the tube.

The current of air blows the powder and plastic simultaneously when they come in contact with the water on ductile material. Moisture is absorbed.

The final end of the motor also rotates the initial gear. Initial gear sets another gear into motion.

When the ductile material moves through the circulating ring of the elastic strips, elastic strips brush the material, and the rotating direction of the plastic material is altered.

In this way, surfaces of the ductile material interact with the dry powder and become dry.

What Are the Applications of Honeycomb Dehumidifier Dryer?
