Hopper Dryer | The Definitive FAQ Guide

The Hopper Dryer FAQ Guide is a free, easy-to-read guide with everything you need to dry various plastic materials using your Hopper Dryer successfully.

The guide contains information on hopper dryers, parts of the hopper dryers, types of hopper dryers, technical specifications, the kind of plastic materials you can dry with your hopper dryer, and much more.

This guide will offer you practical information about hopper dryers that you will not find anywhere.

1. What Is A Hopper Dryer?

A hopper dryer, also known as a plastic dryer, is a drying machine commonly used in plastic extrusion and blow molding to rapidly and efficiently remove moisture from plastic pellets, flakes, granules, and powder.

The moisture content of the pellets is referred to as their “raw moisture content.”

The raw moisture content will vary from material to material, with common values being 4-6% for PVC pellets, 6-10% for ABS pellets, and 10-15% for PS (Polystyrene) pellets.

2.How does a hopper dryer work?

The hopper dryer firstly heat the ambient air by heater coil, and then pass through plastic resin hopper . So the mositure from the resin pellets are dried up and brought out of the hopper.

3. How Hopper Dryer Is Beneficial In Injection Molding and Extrusion Processes?

The Hopper Dryer plays a crucial role in the injection molding process. It is used to remove the moisture from different plastic materials injected into the molding machine. The drying process takes place before the parts are transferred to an oven.

The Hopper Drier is used to reduce the moisture content of extruded plastic pellets before they are processed into finished parts. This process provides an uninterrupted flow of raw materials for all extrusion processes.

4. How Many Kinds Of Hopper Dryer In Yushine Company?

Yushine company offers 2 types of hopper dryers:

Hot Air Hopper Dryer

A hot air hopper dryer is used to dry plastic granules by allowing the hot air to pass through the material placed within a hopper. In this dryer, the temperature can reach up to 1800C. You can use it to remove non-hygroscopic materials, including ABS, PS, and PP.

Hot Air Chiller

Insulated Hopper Dryer

An insulated hopper dryer is a device used to dry materials containing moisture. The stainless-steel hopper is double insulated. This increases the efficiency and effectiveness of the drying process.

No heat losses are associated with the insulated hopper dryer. The temperature in this type of hopper dryer reaches up to 2000C.

5. What Are the Main Parts of Hopper Dryer?

Various parts, when combined, make up your hopper dryer. Without a single of these parts, your hopper dryer will be unable to perform its function. These components include:

Air Filter

Air filters are one of the most important components integral to the smooth operation of hopper dryers. It helps maintain a better airflow which indirectly prevents any accumulation of lint and dust inside it. This elongates the life of the hopper dryer.

Air Filter

Blower

The primary benefit of a hopper dryer is the circulation of dry, hot air into the hopper. These blowers consist of scroll compressors and fan motors to effectively circulate the air. This circulation causes moisture to evaporate, so less water remains inside the grain and generates a higher quality product at the end of drying.

Blower

Heater

The heater is the essential component of the hopper dryer. It contains a programmable timer, power density, and excess temperature control. The main role of the heater is to raise the temperature of the air when it passes through it. You can specify the temperature or set its value. This will help you speed up the drying while also giving you control to prevent excessive temperatures.

6. What Are the Applications of Hopper Dryer?

There are many industries that need hopper dryers. Below is a list of main applications :

The plastic industry uses this product to remove the moisture from material so that the end products are of high quality. The pharmaceutical industry utilizes hopper dryers to produce high-quality drips, syringes, oxygen masks, and much more.

The food industry uses a hopper dryer to completely dry out recyclable plastic products, including disposable glass, tea mugs, plates or spoons, and much more.

Different beverage products, including recyclable glasses and beverage containers, also utilize hopper dryers in their manufacturing process. You cannot ignore the importance of hopper dryers in these industries.

7. What Plastic Polymers or Materials Do You Dry Using Your Hopper Dryer?

Multiple materials you can dry using your hopper dryer. Some of the main materials include:

ABS (Acrylonitrile Butadiene Styrene)

ABS is a synthetic polymer widely used in manufacturing to be molded into almost any shape. It’s fairly easy to develop and yet very durable. The versatility that comes from this unique property makes it the most commonly used plastic and one of the most widely used manufactured materials.

PP (Polypropylene)

Polypropylene is a thermoplastic polymer produced from the polymerization of propylene. It is used in various applications, including films, bottle caps, packaging, injection molded parts, and lids for food and beverage cans.

PS (Polystyrene)

PS (Polystyrene) or poly(styrene) is a synthetic aromatic polymer made from the monomer styrene. It is one of the most widely used plastics. PS is an alternative to most plastic materials when making a wide range of products like Electronic items, Furniture products, Shoes, and toys.

8. How Air Filter Contributes to The Material Purification in Hopper Dryer?

The air filter is an important part of the hopper dryer. It is used to purify the air of bacteria and dust particles to achieve a better drying effect. Air enters the hopper through the grating, leaving most foreign matters stuck in the filter.

It prevents these contaminants from harming your hopper dryer and the material you will dry with it. In this way, the material you obtain from the hopper is completely purified and cleaner.

Without the Hopper Air Filter, the fumes from the heating process would be difficult to control, and it would not be possible to achieve an efficient, pollutant-free drying environment.
