Cooling issues of PET polyester chips
Thread Content
For PET polyester chips, after drying during the production process, they need to be cooled to the packaging temperature, and it is necessary to prevent discoloration caused by excessive temperatures. What are some good cooling methods?
Powder flow static water cooler, plate-type heat exchange: two stainless steel plates are spot-welded together and then expanded into shape; water flows inside the plates while the material flows on the outside. This design enables efficient heat exchange through water cooling, eliminates dust emissions, reduces energy consumption, occupies less space, and replaces traditional fluidized bed cooling methods.
How can slicing be done without cooling down? ? ? Doesn’t the pelletizer have built-in cooling for its three water streams?
