COOL DOWN

After the heat cycle the load must be cooled to a "comfortable" temperature.  Of course, "comfort" is an opinion.  For example, my wife believes that 110 degrees-F is a comfortable bath temperature, while I find that to be a little too hot for my liking.  The granddaughter needs a much lower bath temperature, of course.

 

Obviously, being fully immersed in a temperature is different than handling items of various temperatures.  For example, the new iPad, a handheld device, is said to reach temperatures of up to 116-degrees.  This temperature is not extreme, yet it may become uncomfortable to hold on to for an extended period of time.  

 

Unlike the iPad, when working with laundry, the hands are not in constant contact with the product.  Thus, temperatures can be much higher for laundry handling.

 

Finding the perfect cooldown temperature can be a very important issue for operator safety and comfort.

After the load is dry, a cooling process is required to prevent burned hands or to prevent product wrinkles or product damage.  Final temperatures used for the cool down process may depend on the type of products, themselves.  It may also be determined by the method in which the dryer discharge is handled.  For example, bath towels are typically cooled to a temperature range of 125-F to 140-F.  If no one will handle the towels until they are conveyed, dropped into a sling bag and railed to a finishing station, the operator might cool down to 140-F or higher, with the knowledge that these loads will cool further prior to human contact.   
 
Although cool down temperatures used are determined by each laundry, the following is a good rule of thumb to go by.

This little outdoor dryer has heat, rotation and airflow, just like an indoor unit, but cool down might require a push into the shade.
