The material stuck in the loop because too little material remains and the temperature isn't rising

Here in this screenshot I am melting Phosphorite, but my loop is now stuck because there is too little phosphorite remain, 312 mcg left and no new phosphorite can come in. How could i deal with this?

Ha yes, the classic "less than 1 gram of mass doesn't transfer heat" problem. I found no better solution than to route some packets back to where they came from at regular intervals. Tiny packets eventually find their way out and get merged back into the source pile that way. Using a weight plate to ensure the input pile is large enough to prevent such scenarios may also work.

You could add a detector that lets a packet through if the thermal sensor keeps things blocked for too long. If normal heating takes, say, up to 100 sec and the sensor blocks for 200 sec, let that packed through and just drop it. Eventually enough will accumulate that it takes heat again.

I ran into the same issue melting ice. My solution was to set up automation with a thermo sensor, weight plate, and a conveyor meter.  If there's no weight on the plate, and the temperature is high enough, trip the conveyor meter.  It opens up, feeds a set amount, turns off.  The set amount drops onto the plate until it melts and the liquid sloshes away to start the cycle over.
