Hello all! First time posting here. I have briefly searched the forums and I haven't (yet) seen anyone with experience who can confirm whether what I am suggesting is possible. We ideally want to build as sustainable a miniature kitchen as possible within 145cm across by 120cm tall by 230cm deep cattle trailer. We are likely to raise the roof or make it removable. The sort of rocket stove design I am imagining is a row of steel chambers insulated within an oblong outer-container to create a row or platform of hobs. the woodfeed and air-flow would protrude from the bottom-sides or front of the stove I imagine. The idea is on heat for cooking, not for heating. we're also gonna have a sink/basin for cold-ish Russian washing, a platform for food prep, lots of clever under and overhead storage, and maybe some clever steel platform heat distributor that will make a big flat hot-plate type thing for frying. A deep friar would be awesome too (vegan scotch eggs and tempura guys!!!) but I predict it will be dangerous if not impossible to control the heat necessary to deep fry food.
big loves to you guys, we've already got the trailer so if someone says the plans impossible because the stove will erode too quick, it won't be able to be driven, trailers not strong enough, fire hazards, pesky health'n'safety and food regulations.... then just throw some ideas into the proverbial RMH pot and we'll see what will happen
What's the total weight rating on the trailer, and how much weight do you think you can allow for the stove? Max axle weights? Will you be putting it over the axles? Can you link to a picture of what you mean (a cattle trailer where I live is huge)?
Your measurements seems pretty small for a kitchen, are they right (esp height)? Is that just the space for the cooker?
The notion of a "sustainable" mobile trailer kitchen is amusing... the materials and use case are inherently unsustainable But that aside, it sounds like you could build a workable rocket stove using mostly insulated metal components, leaving just the combustion zone to be lined with masonry. I think a design that allows firebricks to be replaced when deteriorated, and locked in place to avoid vibration movement, could work. An all-metal unit with heavy steel combustion zone if used infrequently might even work for a good while. How frequently do you envision moving it, and how far? How often do you plan to use it?
I have a steel camping rocket stove which is 4 inch, 100mm square tube into an L its 12 x 16, 300mm x 400mm (long side) and 8 x 12 200mm x 300mm (short side). I put in a metal box filled with perlite as insulation and this improved its performance considerably. The big question is how long it will last as steel has a short life with rocket stoves. I think a J style would be a lot easier to use than the L that I built and if I make another then I will go that way.
Deep frying can be done in a wok, which would give you more control but it sounds like you want to produce commercial quantities so this may not suit you. Remember that temperature control is essential when deep frying both for food qualitity and to stop it turning into a raging inferno!!
