daniela, the procedure for erev pesach is to state that everything that is left over/falls/crumbs etc. will be batel before they become hametz. If you have a wood fire going, then of course you sweep up and toss it in the fire. You could also flush it down a drain. It helps if you are a micro op and your cycle is way shorter than 18 minutes.
Saluf pan: Saluf is a teimani fluffy pita type bread made in present times in a cheap aluminum deep fry pan, with a electric element added, and a plug, very much like a free hand manual toaster, but with more wattage. It can be used over a skillet on a stove, or stand alone with just another fitting lid. The single heater set-up is used with the heat above the bread as a boiler.
For (ashkenazi)matzos, you want heat from above and below, so the saluf pan over a heated skillet, or a double saluf pan with heater top and bottom. My setup is 54cm round, and I do one, or two matzos per cycle, and my matzos are small, heavy whole wheat. If you can do only one at a time a smaller version 25-27cm fits on a stove top like a large pot. These things weigh almost nothing. I don’t know what you would do to make them suitable to 110V. Here you can get oven elements made to order. The down sides are that like a pizza oven, you don’t see the baking, you need to know your dough and oven and have the timing down, otherwise the matzos can be easily incinerated. They are unspeakably cheap junk, and the labels indicate they are made in Jordan or in the PA. I have plans to build my own, in welded steel, with rectangular elements to get away from the cheap.
For the handy, anything that can bake a pita, with some slowing down, or heating up, can bake the much thinner, less water containing matzo. I have seen a table top pita baker that had a metal mesh link belt and internal toaster arrays. The wet pitas were fed onto the belt, and they came out the other side baked and puffed up. If the mesh were narrowed to hold a matzo, either slowing the transit or beefing up the heater would do the job, and the belt always moving past the heaters is continually kashered.
