Overview of the Multi-Bread Production Line
The multi-bread production line is a complete continuous flatbread plant. Dough enters at the chunker and leaves the line in sealed bags. Between those two points it is sheeted, laminated, dusted, brushed, docked, cut, proofed, baked, cooled, counted, stacked and packed without an operator handling the product.
What sets this configuration apart from a single-product line is the baking section. Two tunnel ovens run in parallel from one shared make-up and proofing front end, so products with incompatible bake profiles no longer have to share a single time-and-temperature curve.
Why the Line Carries Two Ovens
A pocket pita and a thick, docked pita bun come from the same dough family but need opposite bakes. Pocket bread depends on a very short, very hot bake: the sheet has to separate into two skins before the crust sets. A pita bun is docked precisely so that it will not puff, and needs a longer, more gradual profile to build colour and finish the crumb.
Running both through one oven means one product is always a compromise — an underdeveloped pocket, or a bun that colours before it is baked through. Two ovens remove that trade-off:
- Infrared with Ribbon Burners Tunnel Oven: combines infrared radiant heat with multi-ribbon gas burners for the shortest, hottest profiles — typically the route for pocket-forming breads.
- Ribbon Burners Tunnel Oven: direct-flame ribbon burners with a longer, more controllable profile — typically the route for thicker, docked, pocketless products where surface colour and crumb matter more than puffing.
Which product runs on which oven is confirmed during product trials rather than assumed from the product name. Both ovens are fed from the same proofer through a transfer section, so the line runs one product at a time on the oven that suits it.
The Line, Stage by Stage
- Dough feeding and chunking. Bulk dough is loaded into the hopper and cut into a controlled, continuous flow onto the first belt. See the dosing hopper.
- Progressive sheeting. A satellite dough sheeting head reduces the sheet gradually and with low stress, followed by a dough lamination head and a series of gauging stations linked by dough sheeting conveyors.
- Cross sheeting. A cross sheeting unit rolls across the direction of travel to even out cross-web thickness and improve formed-product geometry.
- Dusting and brushing. A flour sifter feeds the flour duster, and upper and lower brushes remove the excess before the sheet is cut.
- Docking and cutting. The dough docker perforates products that must not puff; the rotary dough cutter cuts round or square blanks from the sheet, and scrap removal conveyors return the surrounding web.
- Proofing. A multi-layer cascade belt proofer holds the residence time and proofing conditions in a compact footprint.
- Baking. A transfer section routes the product to the infrared or the direct-flame ribbon burner oven.
- Cooling. A spiral cooling tower brings the product down to packing temperature; cascade and hanging cooling conveyors are alternatives where floor space or layout dictates.
- Counting and stacking. The counter stacker builds the retail count.
- Bagging. The bread bagging machine places the stacks into pre-made bags.
- Accumulation. A rotating table collects finished packs for case packing or manual removal.
Breads This Line Produces
The approved product list is fixed during the project, but this configuration is built around the following range:
Adding a product outside this list is often possible, but it is a trial question rather than a settings question: dough behaviour, forming route and bake window all have to be validated first.
Every Line Is Custom-Built for Your Plant
There is no catalogue version of this line. Farhat customizes each multi-bread production line around the customer’s products, required output and available floor space, so two lines built from the same stage list can differ in almost every dimension.
What is specified per project rather than fixed in advance:
- Machine selection. The stage list above is the full route; a project carries only the machines its approved products actually need. A line that never makes a pocket bread does not need the second oven.
- Working width and rows. Belt and sheet width, the number of lanes and the product pitch follow the piece size and the target output — they are not a standard frame you have to design around.
- Oven length and zones. Bake time and the number of independently controlled zones come from the products and the throughput; oven length is then whatever that profile requires.
- Proofing capacity. Residence time decides the number of tiers and the footprint of the cascade belt proofer.
- Cooling method. A spiral tower, a cascade conveyor or hanging conveyors, chosen against your ceiling height and floor area rather than by default.
- Layout shape. The line can run straight or be folded into an L or a U using transfer and curved conveyors, so it fits the building you already have.
- End of line. Stack count, bag format, bagger model and the interface to case packing follow your packaging specification.
- Level of automation. How much of the line is automated, and where operators stay in the process, is a labour and budget decision taken with you.
Send the plant drawing with ceiling heights, column positions, door openings and utility points together with the product brief, and the proposal comes back as a layout for that building — not a standard line you have to make room for.
Capacity and Line Balance
Output is set by the narrowest stage, not by the fastest machine. Sheet width, product pitch, number of rows, proofing residence time, bake time and the speed of the counter-stacker and bagger all constrain each other. A line that runs one product at full rate may run another slower simply because the piece is larger or the bake is longer.
Farhat quotes net sellable output per product, measured at the end of the line, rather than a single headline figure taken from one machine in isolation.
Changeover Between Products
Changeover time is a design input, not an afterthought. On this line a product change can involve roller gap settings, docker and cutter tooling, proofing residence time, oven selection and zone recipe, stack count and bag format. Stored recipes hold the settings; the tooling changes and the cleaning required between them are agreed for the actual approved range.
Hygiene, Utilities and Installation
Food-contact materials, guarding, access for cleaning, removable parts and the dry- or wet-clean method are defined in the final design. Gas, electrical, compressed air, water and extraction requirements are confirmed against the plant, together with elevations, transfer heights and the space needed around the ovens and the proofer.
Planning a Multi-Bread Production Line
To scope this line, Farhat needs the product range you intend to run with a reference sample or specification for each one, the recipe or key dough parameters, target weights and dimensions with tolerances, required net output per product, package format and count, your factory layout with available utilities, and the installation country. Related configurations include the bread production line, the pita bread line, the continuous sheeting production line and the dough make-up line.
