Description

 

A plastic honeycomb dehumidifier dryer machine removes moisture from plastic materials by using a continuously rotating desiccant rotor in a closed-loop air system. The process involves adsorption, regeneration, and drying of the plastic pellets.

 

 

 

Working Mechanism

The system operates in a continuous cycle involving several key stages:

 

Drying Process Air Loop:

1.Humid air from the drying hopper (which contains the wet plastic pellets) is drawn into the dehumidifier.

 

2.This air passes through a filter and then the honeycomb rotor, which contains hygroscopic materials (like silica gel or molecular sieves) that act like a sponge, absorbing the moisture from the air.

 

3.The resulting dry air, with a very low dew point (often as low as -40°C or -50°C), is then heated to the specific drying temperature required for the plastic material.

 

4.This hot, dry air is blown into the drying hopper, passing through the plastic pellets and effectively drawing out their internal moisture.

5.The air, now humid again, returns to the dehumidifier, and the closed loop cycle repeats.

Honeycomb Dehumidifier - Hopper Dryer Benefits

1)Ultra-Low Dew Points: Reaches consistent dew points of -40°C to -50°C. dew points of -40°C is our standard design,optional purchase is dew points of -50°C.

This level is essential for extracting internal moisture from engineering plastics.

2)Elimination of Structural Defects: Prevents common injection molding and extrusion flaws. It successfully stops bubbles, silver streaks, cracks, and poor transparency during plastic processing.

3)Contamination-Free Operation: The solid molecular sieve rotor structure avoids degradation. It prevents the dust contamination common in older dual-barrel desiccant bead designs.(that is a key advantage of molecular sieve rotor technology.)

4)Energy and Thermal Efficiency: Insulated hopper designs utilize downward-blowing air and cyclone exhausts. This recycling loop minimizes heat loss and lowers power consumption.

5)No Moisture Regain: Closed-loop feeding systems feature integrated shut-off and suction cutting valves. This ensures no dried material remains stagnant in tubes to reabsorb ambient humidity.Closed-loop conveying systems prevent dried materials from absorbing ambient moisture by eliminating stagnant material in the transfer lines.

The continuous rotation of the honeycomb wheel ensures that one section is always actively dehumidifying the process air while another section is being regenerated, allowing for uninterrupted operation and stable, low-dew-point air essential for high-quality plastic processing. This process prevents common plastic defects such as bubbles, silver lines, and poor transparency caused by moisture.

Honeycomb Dehumidifier – The Definitive FAQ Guide 

How do I choose the right dryer for the plastic processing industry?

we can explore factors to consider, such as the specific plastic material .To determine the appropriate size for a drying hopper, use the formula: hopper load (kg) = throughput (kg/nr) drying time (hr). Then, adjust for a safety factor by multiplying by 1.2.

What Is the diference between conventional dryers and honeycomb dehumidlifers in the plastic processing industry?

Common design dryers use high temperatures to dy materals, which can be less effective in humid envronments as exteral moisture affects the drying effciency. These are typically more suitable for materials with low moisture absorption. especially in colder regions. on the other hand.dehumidiying dryers such as honeycomb dehumidifiers, maintain a low dew point that is not influenced by external humidity. making them ideal
for materials with high moisture absorption, like nylon,PET,PA

What is a Honeycomb dehumidifier?

PET Honeycomb Dehumidifier is the equipment you can use to eliminate the moisture from various plastic materials.Honeycomb dehumidifier Plastic auxiliary Equipment works with humidity control. It has high adsorption ability, energy-saving, and fast-absorbing speed.

Honeycomb dehumidifier dryer can effectively reduce the material's moisture content and shorten the product drying cycle time. PET Honeycomb dehumidifier dryer will help you achieve the high quality or end product through injection molding or plastic extrusion processes.
