Analyze the advantages and disadvantages of the two heating and cooling schemes
Thread Content
A simple production process: Two powdered materials, A and B, are mixed evenly and then heated to 70–75 degrees Celsius. Material B is a thermoplastic with a melting point of 65 degrees Celsius; after thorough mixing, the mixture is cooled to 30–35 degrees Celsius before being filtered and packaged. Now, the following two processes are intended to be adopted: 1. Heat and mix using a double-cone dryer, then discharge the mixture and cool it with air flow in a fluidized bed or cyclone separator, before packaging it. 2 Use a heat transfer oil system with cooling functionality for one-time heating followed by cooling, with the resulting product being screened and packaged. I would like to ask which of these two options is more energy-efficient, and whether there is a better process flow that can be used. Thank you!
One of the problems is that the well-mixed material lacks fluidity, tends to get stuck on the mixing blades or in areas where it is difficult to reach; cleaning is likely the first thing that should be considered. My plan is to use ice machines for cooling and heat exchange; as for air cooling, I haven’t thought yet about what equipment could be used for that.
