Dehumidifying Dryer

PET resin drying is the first step to have good quality bottles. Moisture must be taken out before injection. We always recommend to use dehumidifier which recycles heat to use energy wisely and to get PET dew point to -40°C or blow so that PET exhibits its optimum nature.

Most people choose one of the two options as shown below.

Why Use Dehumidifier Dryer?

Have you seen defects on the products such as bubbles, silver lines, flaws, poor transparency? 80% of problems in PET manufacturing are linked to the drying process. This is due to the fact that PET (polyethylene Teraphthalate) is a very hygroscopic material - meaning it absorbs water into the molecular structure. The moisture absorption occurs through exposure to the environment during transit and storage. To insure optimum properties, PET must be dried to less than 0.02 % moisture prior to melting. Proper drying means a better products. Using general hopper dryer certainly is not sufficient. Dehumidifier can provide dried air to dew-pont down to -40°C which can dramatically reduce the moisture of PET resin and optimize its nature.

Hopper Dryer

For some plastic resins such as PP, PE, ABS, PS, ... it might be acceptable to use hopper dryer only because these materials usually don't have as much moisture as PET does. Choose these reliable hopper dryers below for your plant.  They will satisfy your need.

Note: Optional parts such as preheating timer, filters at the entry and/or air discharge, magnetic grid, floor stand and suction box can be selected upon request at extra charge.

 

 

Autoloader

Several types of autoloader, split or one-piece set, carbon brush or induction, 1 to 1 or 1 to 2 autoloader can be selected according to specific project. In some cases, both split and one-piece autoloaders will be required. For example, the Layout B, the first one-piece autoloader is for bringing material to the hopper dryer and the second split autoloader is for delivering dried material to the injection molding machine. The table below shows some models to selection.
