Summer: Birds are chirping, flowers are blooming, and scrap rates are up!
这不仅仅是你;夏季的时间可以在加工和处理塑料材料 - 特别是潮湿的材料，易于服用水分的挑战。让我们快速看看为什么，以及如何帮助避免这些问题，无论月份如何，都要制作一致的产品。
In this blog, we will touch on 3 key considerations for drying plastics in the summer months:
- Dryer design
- Dryer Maintenance
How Dryer Design Impacts Drying Plastic in the Summer:
Single Blower Dryers:This means that the blower used to dry plastic is also used to purge the system of moisture. This loss in air from the system requires the dryer to make up the air from the surrounding room. This is typically done through a hole in the system that is located in the filter housing. In the summer, this air is very wet and humid.
双鼓风机烘干机：The alternative is separating the two functions to different blowers. In a dual blower design, one blower is for drying plastic, and a separate, smaller blower is for regenerating the desiccant or purging the moisture out of the system. At Conair, we use this “dual blower” design because it has the advantage where the only moisture that our dryer sees is that which is taken out of the plastic. It is a totally closed loop that is unaffected by the environment.
Dryers are designed to control four major variables in thedrying process:
However, there is another critical variable that dryers can’t control, and that is the initial moisture content of the material you are drying.
Plastic gains moisture depending on the type of material, the environmental conditions, and the time of exposure. In the summer, your environment is more humid, so material can gain higher amounts of moisture at much faster rate.
如果你想想initial moisture content like running a race, the further from the finish line you are, the longer it will take to get there and the more energy you will have to use.
To combat this issue, it is a good idea only to open the bags of material you plan you use within a few minutes or hours depending on your material and environment. Any unused materials should be put back in re-sealed bags and boxes.
如果你打算2018世界杯狗万滚球app, you may want to consider a dry air blanket to help maintain moisture while material sits idle.
Check for Air Leaks in Your Drying System
Air restrictions such as crushed hoses or dirty filters can hamper airflow in the system and rob the process of critical air required for drying.
Filters should also be cleaned frequently and changed regularly to ensure good airflow.
The actual frequency of filter maintenance depends on the quantity and quality of material that you process. If excessive fines or particulate are present in the material being dried—or in ambient plant air used in drying or regeneration—a dust collector can be added to the intake/return air circuit to reduce the burden on the filter and extend filter maintenance intervals.
Inspect the Effectiveness of your Dryer’s After Cooler
After cooler effectiveness can also play a part in your dryer’s efficiency and process stability.
To work efficiently, desiccant likes cold air. The after cooler plays a big part in cooling the air down.
该怎么办：If you are using a water-cooled dryer, make sure you have good flow and water temperature. It may also be a good idea to pull the coil periodically for a thorough cleaning.
Unlike our competitors, all Conair Dryers come with some sort of internal after cooler. It’s not an add-on or upsell. In some cases, this after cooler is air-cooled and in other cases, it’s water-cooled depending on dryer size and customer preference.
Keeping Plastic Material Dry No Matter the Season
That’s it. Running a dryer in the summer that’s as easy as one, two, three.
If it seems like a lot to remember, don’t get intimidated. All Conair Plus and Premium controls come withmaintenance alerts and remindersthat enable the dryer to tell you when it’s time to do the work.
