The Physics of Hot Pockets

StartsWithABang (3485481) writes "You've all had the experience: you're all excited to microwave your favorite snack. So you pull it out of the freezer, you throw it in, and you let it rip. A minute or two later, you pull it out, and there it is: boiling on the outside, frozen in the middle. Finally, a physicist answers the eternal question: why do microwaved foods remain frozen on the inside when they reach scalding temperatures on the outskirts?

      Of course there are microwaves made with competent stirrers and well-placed feeds. Panasonic makes microwave ovens that feature both (the feed is at the bottom of the cavity), so no rotation is necessary. They also use variable fast pulse width modulation to drive the magnetron, resulting in a smooth output power, thus avoiding another common contribution made by on-off duty cycles to burnt skin / frozen middle problems especially at lower power settings. (Triac controlled magnetrons can only go on and off; most PWM microwave ovens not driven by an inverter supply do a cycle on the order of 30 seconds.) There is work on continuous phase shifting, which will avoid heating the same islands in food even in pessimal cases (like poorly conducting food put in the centre of a rotating tray). Finally, there is still substantial research going into probes inserted into food so as to provide feedback to the driver logic (dynamically or for capture into programs which take food type mass as variables) and whether non-invasive probes can provide useful dynamic feedback every time the oven is in use.

The critical path and most visible extra cost to the first time buyer is mainly in the design of trays and dishes which work well under arbitrary conditions in a combo oven, and avoiding damage when someone uses the wrong tray, dish or tool for a given programme.

This is a global problem, not unique to the USA.

      I think your comment is misleading, for it incorrectly implies that the main problem is cheap microwave ovens and directions to "the masses" about how to use them on food packages. In my opinion, this is wrong for the following reasons.

      Firstly, the stirrer technology is you refer to is just a some rotating metal near the magnetron. It is more than 20 years old. By and large, it sucks. That's why it has been replaced by the rotating carousel, which is far superior and why you cannot, actually, buy it easily today in a new microwave-capable oven unless rotation is ruled out for a different reason. However, field unevenness in no way is the main cause of the problems discussed in the article, which is not one-sided heating, as can be the case in non-rotating ovens, but that heating is concentrated in already defrosted areas and food edges/corners.

      In other words, even with a perfect EM radiative bath the edges and corners of a hotpocket will still burn or be overcooked if heated rapidly enough while the center is still frozen. That's why even if you buy the most expensive microwave oven on the planet, it will still have this same problem of producing food that is overcooked on the edges and the corners, which experience the highest EM radiation. The cause is not any unevenness of EM modes in an unloaded oven cavity. Rather, it is the shielding effect of food and the relatively small field skin depths to food size ratios.

      Your comment about pyrolytic surfaces is interesting, but also misleading, for it implies that convection microwave ovens solve the problems discussed in the blog post. The problem is that microwave ovens use steam cooling of the corners, which boil and splatter food all over the oven as the steam turns things like beans into tiny bombs. Even with simultaneously convective and microwave ovens, of which I own one, one still has a frozen center burnt corner issue, since convective heating is even worse at edge heating. The reason is of course that the convective oven relies upon thermal conduction, which is entirely skin heating, although in truth one gets some infrared radiation which can penetrate a little bit.

      You asked,

      why not cook with microwaves and brown with the grill simultaneously?

      Great question. Ceramic would work for that, but it is expensive. Traditional stainless steel grills are conductive, so they would reflect the EM radiation back into the magnetron, which will shorten it's life. So here is where your comment is spot on; it is indeed a cost and consumer ignorance issue, although grills have other issue I won't go into here. Regardless, dual mode ovens do not fully fix the underlying issue anyway, which, again, is over the overheating of food portion edges and corners.

      The primary reason one probably sees less burning in dual-mode ovens may come as a surprise. This just my hunch, but, in my opinion, it is primarily because dual-mode microwave/convection ovens tend to have a larger cavity. The FCC regulates how much leakage can occur in a microwave oven, and there is more cavity area. So larger ovens have to have less maximum magnetron power, due to the FCC. Therefore, dual mode ovens tend to use less magnetron power, which gives more time for conductive heating to defrost the food centers. Another alternative reason has to due with the amperage limitations of most nema (or other) sockets. If there is power going to a heating coil, that's less power for the magnetron. Same effect, however; longer time to cook = more time to thaw cent

The directions are usually for a 1000 Watt microwave (some products calibrate for 1100W for some reason). That's what my current unit is, so that's easy. If the microwave is 900W, you nuke the food for 10% longer, so if the directions call for 3.5 minutes you convert that to seconds (210) and add 10% (21), giving 231, then convert that back to minutes and seconds, which is what the microwave groks (3 min 51 sec). Stupid easy.

    I have had the author's described problems when heating up leftovers, especially stews.

    Microwave bacon.

    Seriously. This coming from a bacon lover who saved the rendered bacon lard from all his bacon frying adventures. Once you go microwave bacon, you never go back. Perfectly crispy every time.

    But you don't get to save all the bacon lard, unfortunately. Good thing I still have a solid 8 oz. left from my frying days.

    I'm aware of the rack, but I've already got way too much shit in the kitchen. One day, it came down to the microwave bacon rack or the immersion blender, and I decided the immersion blender was way more valuable to me.

    Finally someone who got it right. GP is wrong about the Joule heating; ultra-pure water with near-zero conductivity heats just fine in the microwave, as do oil and dry carbohydrates, and insects do die if they don't manage to go sit at a node in the standing wave, only they seem to actively seek these nodes by moving to where it feels least hot. That said, it seems plausible that there is some joule heating in actual food, and it could even help explain some weird heating patterns; it's just not the most important contribution overall.

    TFA at the very least used unfortunate wording suggesting rotational resonance, which would also be wrong. This is a pervasive urban legend even amongst people who should know better, and can even be found in some entry-level textbooks (see the scan in TFA). The misconseption is based on the fact that molecular rotations for gases are indeed located in the microwave spectrum. However, molecules don't really rotate freely in the condensed phase (and the peaks for water vapor are at 22.2 and 183GHz anyway so the frequency of the microwave oven would be far off). Dielectric heating is the only correct explanation. That said, it does seems plausible that the dielectric heating of liquid water is more efficient than that of ice because of the more persisten hydrogen bonds, so TFA probably got that part right.

    In summary, both GP and TFA got their basic mechanism wrong but contain some good arguments nevertheless.

    Perhaps you missed the direction about cooking the hotpocket inside the crisper it comes with in a 1100 watt microwave oven; preferably in a microwave with a rotating carousel. Or possibly the direction to let it sit for 5 minutes after cooking.

    A minute or two later, you pull it out, and there it is: boiling on the outside, frozen in the middle. Finally, a physicist answers the eternal question: why do microwaved foods remain frozen on the inside

    Because the microwaves are high energy, they are absorbed or dispersed near the surface, when they come into contact with compounds such as water.

    The heat takes much longer to conduct through the material, than microwaves take to hit the material, therefore: the center takes longer to be heated.

    Would microwaving frozen food in a vacuum (or conversely under high pressure) make any useful difference in how evenly the food cooked? A lower pressure would lower the boiling point and a higher pressure would raise it. What about subtly modifying the wavelengths or amplitude? I'm not a physicist so I have no idea. Just throwing that out there to see if someone smarter than me can make it stick.
