Stage 3 Grinder: Industrial Fresh & Frozen Mincer (CM-250)

The Stage 3 Grinder (Model CM-250) is the "workhorse" of the industrial bone processing line. Constructed from high-quality stainless steel with a low-noise, reliable structure, it uses a powerful rotary screw mechanism to push material to the precut-plate with immense force.

Designed to accept the 15mm output from Stage 2, it refines the product into a consistent, commercially viable ground meat/bone mince using precise relative movement between the knife and hole-plate.

Step 3: Integrated Workflow

Input Requirement:

For Pet Food & Bone Lines: When intended for dog food production, this machine is optimized to process pre-crushed material (approx. 10mm - 20mm). For the smoothest operation and highest throughput in these applications, this unit should be fed directly by our Stage 2 Roller Crusher. The consistent small chunks ensure the grinder runs at maximum efficiency without jamming.

For Standard Meat Processing: For other standard heavy-duty applications (such as fresh or semi-frozen meat blocks), this powerful unit functions excellently as a standalone grinder and does not require pre-crushed input.

Input Material: Stage 2 Crushed Bone Mince

INPUT: Output from Stage 2 (15mm Chunks)

Operational Output: Precision Mincing

To create an excellent cutting result, different hole-plates (from φ4mm to φ35mm) can be selected according to your specific processing requirements.

Dual-Application Technology

The CM-250 is versatile enough for both fresh and frozen applications by utilizing specialized interchangeable screws:

Fresh Meat Screw: Optimized for cutting fresh meat cleanly without smearing.
Frozen Meat Screw: Essential for processing frozen blocks or meat/bone mix between -3°C to -10°C. This screw is designed to make the raw meat reach the required product texture efficiently.
Low Noise & Reliable: The main body and food contact areas are made of quality stainless steel with a reasonable structure for reliable, quiet performance.

OPTIONAL Step 4: Do you need Emulsified Paste?

If your product requires a "soupy" or paste-like consistency (e.g., for hot dogs, lickable pet treats, or liquid fertilizer), the ground output from Stage 3 must be emulsified.

We recommend the Model CM-240 Paste Maker to turn this ground meat into a superfine, micron-level paste.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
