What you make decides what you need. A restaurant doing its own bread, its own juice and its own mezze will want three machines from three different parts of a catalogue.
Dough
Spiral mixers, planetary mixers, dough sheeters, dividers and retarder-provers. For bakeries, and for any kitchen where the dough itself is the point.
Fruit and vegetable
Vegetable cutters, cutter mixers, food processors, peelers, juicers and citrus presses. Usually the biggest volume in the prep window, and the first place a kitchen runs out of time.
Pastry
Planetary mixers, sheeters, moulders and proving. Pastry punishes a variable batch, so the machine has to hold its settings.
Pizza
Spiral mixers sized to the dough batch, dough rollers and portioning, sitting alongside the deck or conveyor oven.
Pasta
Extruders, sheeters and cutters for kitchens making their own, and the cold storage that fresh pasta immediately requires.
Sandwich and deli
Slicers, contact grills, portioning and refrigerated prep counters. On an assembly line the hold-up is usually how far someone has to reach, so the counter matters as much as the machine.
Mezze and regional
Hummus, moutabel, tabbouleh and kibbeh, in the quantities a busy service gets through. A cutter mixer will do the batch inside the prep window and hold the texture from one day to the next.
Meat preparation
Mincers, bandsaws, slicers and portioning, for kitchens that break down their own product. It pays where the menu needs cuts you cannot buy reliably, or where whole carcass works out cheaper than portioned. Dry aging sits alongside this and is covered under refrigeration.
Packing and holding
Vacuum packers for portioning, shelf life and sous-vide, plus the blast chilling and cold storage that prep-ahead depends on.
