Mechanically Deboned Meat and Bone Separation: Equipment Options for Poultry and Fish Processors
Poultry carcasses, fish frames and trimmings still carry usable meat after primary cutting and filleting. Mechanically deboned meat and bone separation systems help processors recover this material in a structured way, turning by‑products into defined raw materials for further processing.
This guide explains key concepts and equipment options for mechanically deboned meat and bone separation in poultry and fish processing plants. It compares deboning presses, bone separators and recovery lines, and describes how to plan layouts, capacities and workflows so that frames, carcasses and trimmings move smoothly through your plant.
Who should use this mechanically deboned meat and bone separation guide?
Mechanically deboned meat (MDM) and bone separation systems sit between primary processing and further processing. This article is especially useful if you are:
- Poultry processing plants handling broiler carcasses, backs, necks and wings after cut‑up and deboning.
- Fish processing plants handling frames, heads and trimmings from filleting lines for further utilization.
- Further processors and central kitchens using mechanically recovered poultry or fish meat as an ingredient in formed products, emulsions and fillings.
- Growing processors looking to move from manual trimming of frames to structured meat and bone separation equipment.
If you are deciding whether to install a standalone deboning press, a bone separator or a more complete recovery line, the sections below give a practical framework for discussion with your team.

What should you clarify before choosing mechanically deboned meat and bone separation equipment?
Before looking at specific machines, it helps to define how MDM and recovered meat will fit your overall process:
- Which species and raw materials will you process: poultry backs, carcasses, necks, wings, fish frames, heads, trimmings or a combination?
- How will mechanically recovered meat be used: as an ingredient in emulsions, sausages, patties, fillings or other further processed products?
- What daily or shift‑based volumes of frames and trimmings do you expect at peak times?
- How close will meat and bone separation equipment be to primary lines, cold rooms, mixing and forming areas?
- Will you operate one centralized MDM line for several primary lines, or smaller systems near each primary process?
Clear answers help you choose the right scale of mechanical deboner or bone separator and plan how frames, trimmings and recovered meat move through your plant.
Which types of MDM and bone separation equipment fit poultry and fish processors?
Meat and bone separation systems follow similar principles but are adapted to different products and volumes. The table below compares common options.
| Equipment type (card) | How it is typically used | Best suited for | Planning points to review |
|---|---|---|---|
|
Poultry mechanical deboner / meat and bone separator Press‑type deboner for chicken or turkey frames. |
Poultry frames, backs, necks and similar materials are fed into the machine. Pressure and a perforated surface separate soft meat from bone and harder material, producing a stream of mechanically recovered meat and a separate bone fraction. | Poultry processing plants with continuous flows of carcasses and frames from cut‑up and deboning lines, and further processors using poultry MDM in cooked products. | Review infeed format (whole frames, pre‑crushed material), required throughput range, available floor space and how recovered meat will be collected and transferred to mixing or storage. |
|
Fish bone separator / fish meat recovery machine Meat recovery from fish frames and trimmings. |
Frames and trimmings from filleting are fed into the machine. A belt or drum with a perforated surface helps separate soft fish flesh from bones, skin and other hard components, generating a recovered fish meat stream and a bone fraction. | Fish processing plants handling species where frame meat can be used in further processed products, such as formed portions, fillings or emulsions. | Check compatibility with your main species, frame sizes and trimmings. Plan how recovered fish meat will be cooled and stored before further processing. |
|
Compact mechanical deboner for mixed applications Smaller deboner for varied raw material streams. |
Used in plants with lower volumes or a wide range of raw materials. Batches of frames or trimmings are fed according to internal schedules, often with more manual loading and handling than large continuous systems. | Smaller poultry or fish processors and central kitchens that want structured recovery of meat from frames without building a full MDM line. | Consider flexibility versus throughput, cleaning access for frequent changeovers and how easily the machine can be repositioned if layouts change. |
Many plants start with a compact mechanical deboner handling one product type and later extend to larger or additional machines as volumes and product ranges grow.
How does a meat and bone separator fit into your overall poultry or fish line?
Mechanically deboned meat and bone separation systems sit between primary cutting and further processing. The table below shows typical positions in a plant layout.
| Line section (card) | Typical position of MDM / bone separation | Suitable operations | Layout notes |
|---|---|---|---|
| Poultry cut‑up and deboning area | Meat and bone separators are often positioned near the end of cut‑up lines, receiving carcasses, backs and frames in tubs or via conveyors for continuous feeding. | Poultry plants supplying fresh cuts and further processed products from the same building, where frames are generated all day long. | Plan separate flows for frames entering the deboner and recovered meat leaving it. Provide space for tub or bin rotation and staging of bone fractions prior to removal from the area. |
| Fish filleting and trimming area | Fish bone separators are often placed near filleting lines, receiving frames and trimmings and feeding recovered meat toward mixing, forming or storage areas. | Fish processors that want to utilize frame meat in further processed products or supply recovered fish meat as a raw material to other plants. | Consider the direction of fillet and frame flows, room temperature conditions and how recovered meat will be cooled or transferred to adjacent rooms. |
| Further processing and mixing area | In some plants, mechanical deboners are close to mixers and forming lines, so recovered meat enters blending and recipe steps soon after separation. | Integrated plants where MDM and recovered fish meat are used primarily for on‑site sausage, patty or filling lines. | Plan for smooth transfer from deboner outlets to mixers or storage tubs, and align capacities so that recovered meat is handled promptly according to your internal procedures. |
Simple flow diagrams showing primary, recovery and further processing sections help you see how MDM equipment ties the plant together.
What operational questions does mechanically deboned meat equipment help you address?
Mechanically deboned meat and bone separation systems influence more than the recovery step. They affect how you plan raw material flows, recipes and staffing.
| Operational question (card) | Role of MDM / bone separation equipment | Typical scenarios in poultry and fish plants |
|---|---|---|
| How can you make better use of frames and trimmings? | Deboners and bone separators turn carcass frames and offcuts into a defined stream of recovered meat that can be built into recipes and planning alongside primary cuts. | Poultry cut‑up lines generating large volumes of backs and carcasses, and fish filleting lines producing frames suitable for meat recovery. |
| How can you structure further processing around recovered meat? | A consistent recovery process makes it easier for mixing and forming teams to plan recipes, batch sizes and production scheduling based on expected recovered meat volumes. | Plants producing products where mechanically recovered poultry or fish meat forms an ingredient in emulsions, patties or fillings. |
| How can you simplify handling of bone fractions? | Meat and bone separation equipment produces a defined bone fraction stream that can be routed to dedicated bins, containers or further utilization processes according to your internal plans. | Poultry and fish plants coordinating removal of bone fractions from production areas to centralized collection points or external partners. |
Mapping how frames, recovered meat and bone fractions move through your plant helps you define where mechanically deboned meat systems add the most value.
How should you size mechanically deboned meat and bone separation lines?
Capacity planning is central to selecting meat and bone separators. The aim is to align recovery capacity with upstream frame generation and downstream further processing.
| Planning area (card) | Questions to ask your team | Design notes for poultry and fish plants |
|---|---|---|
| Frame and trimming volumes per shift | What approximate quantities of frames, carcasses and trimmings do you expect from each primary line during typical and peak shifts? | Align the nominal capacity range of the deboner or bone separator with expected frame volumes, leaving margin for peaks and future growth where space allows. |
| Connection to upstream and downstream steps | Will frames arrive in a continuous flow via conveyors, or in batches using tubs, bins or trolleys? Where will recovered meat go next: to mixing, cooling or storage? | Choose infeed and outfeed solutions that suit your existing equipment and give operators consistent, manageable tasks when loading and unloading the deboner. |
| Staffing and access around the machine | How many operators will work at the deboner during each shift, and how will they move between frame staging, machine controls and recovered meat handling? | Plan clear walkways, access to controls and safe areas for bin changes so that operators can work comfortably and respond quickly if adjustments are needed. |
Simple block diagrams showing primary lines, MDM equipment, mixing areas and cold storage can help you evaluate whether proposed capacities and layouts are practical.
What practical points should you consider when selecting MDM and bone separation equipment?
Beyond headline capacities, day‑to‑day usability influences how well mechanically deboned meat systems fit into your plant. The table below outlines key aspects to review.
| Selection aspect (card) | What to discuss internally and with suppliers | Why it matters in daily operation |
|---|---|---|
| Raw material compatibility and format | Clarify which species, frame shapes and trimming types the equipment should handle and whether any pre‑crushing or cutting is needed before infeed. | Matching raw materials to the machine helps operators feed the system consistently and reduces the need for unplanned pre‑processing steps. |
| Controls, adjustments and repeatability | Review how operators select and adjust settings, and how easily they can repeat preferred settings for particular raw materials or product types during shifts. | Clear, repeatable controls help different shifts run the equipment in a similar way and support more predictable performance across the week. |
| Cleaning and maintenance access | Check how easily covers, belts, drums and contact parts can be accessed, removed and reassembled according to your cleaning and inspection routines. | Straightforward access can support regular cleaning and visual checks, which in turn help maintain stable operation during daily production. |
Involving maintenance, production and quality teams when reviewing equipment options helps ensure that the final choice supports all aspects of daily work.
