  Awesome! 😀
  
  #-Link-Snipped-# - Sir, do you have any way to slow down the melting of ice? I guess, the caging itself slows down the process, but any extra medium that we can combine with? Thanks in advance.

  any way to slow down the melting of ice?

  If there is no air flow the thermocole box will slow down the ice melting. If the fan runs there is no escape from the mCp(delT) (airside) from melting an equivalent quantity of ice. Slowing the fan will slow it at the cost of reduced cooling.

  #-Link-Snipped-# - Sir I was asking about any material which can be mixed with ice to slow down its melting. Is it possible?

  The basic problem is that if any heat is added to ice it will melt consistent with its latent heat. In this case the fan is blowing outside warm air into the chamber. The higher temperature of the air melts the ice.
  Unfortunately, any addition to the water will depress the melting point leading to faster melting.

  I have heard of salt OR pepper being added to salt to make it melt slower.
  Not sure if it's true. Here's a link:

  to make it melt slower.

  Not really. What is said in the reference is the same mentioned in my post. Adding salt lowers the melting point, does not affect the amount melted.

  AS AKNITHA SAID IS CORRECT ADDING SALT TO ICE IT LOWER THE MELTING POINT I HAD DONE IT practically 😀

  The total cooling capacity is still invariant. The latent heat does not change.
