Bone paste grinder

Turn “Waste” into High-Value Paste for Bakso, Sausages, and Broth Concentrates

Stop treating animal bones like garbage.

Last month, I walked into a fish ball processing plant in Semarang, and I saw them tossing 200kg of fish frames into the bin every shift. That isn’t waste; that is pure calcium, protein, and flavor that you are paying to throw away.

In the competitive food markets of Vietnam, Thailand, and Indonesia, the margin is in the yield. If you are still using old-school colloid mills to grind bones, you are burning money—literally. Friction heat kills protein.

The GN Series Bone Mud Machine is not a standard grinder. It is a cold-milling system engineered with German Tungsten Carbide technology that turns chicken skeletons, fish frames, and beef bones into a smooth, 300-mesh paste (mud) without cooking the meat during the process.

Description

The “Cold Grinding” Reality Check

Here is the problem with 90% of the machines sold in Southeast Asia: Heat.

When you grind hard bone against steel in a humid, 35°C factory, friction raises the paste temperature instantly. If your bone mud hits 45°C, the protein denatures. Your Bakso loses its “bounce” (kekenyalan), and your Chả Lụa goes sour faster.

The GN Series is different.

  • Feature:We use HRC 65+ Tungsten Carbide grinding heads with a dual-zone geometry.
  • Advantage:The head cuts the bone rather than crushing it through brute force friction.
  • Benefit:The residual heat increase is <1°C. Your bone paste comes out raw, fresh, and bright pink, preserving the binding quality of the protein. This allows you to reduce expensive lean meat usage by up to 30% without customers noticing a texture difference.

 Why This Machine Survives Tropical Factories

I’ve spent 15 years fixing machines that rusted out in Jakarta’s humidity. We built this one to last.

1. No “Sand” Texture (160-300 Mesh)

A common complaint with cheap bone grinders is the “gritty” mouthfeel. It ruins the product. Our GN series achieves a particle size of 50-180 microns.

  • The Result:When you add this paste to your sausage or meatball mix, it is undetectable. It acts as a natural binder and calcium supplement.

2. The “Anti-Jam” Overload System

Bones vary in density. A thick beef femur is harder than a chicken neck.

  • The Engineering:If the machine detects a hard blockage, the motor auto-reverses instantly to clear the jam, then resumes. You don’t have to stop the line and dig out bone fragments by hand.

3. CIP-Ready Hygiene (Crucial for HACCP)

In our climate, bacteria multiply in minutes. The GN machine features a mirror-polished (Ra 0.4μm) interior.

  • Pro Tip:When cleaning, do not use a high-pressure jet directly on the bearing seals at a 45-degree angle—you’ll force water into the grease. Use the CIP (Clean-In-Place) cycle. It cleans the internal teeth in under 10 minutes without damaging the seals.

 

 Technical Specifications & “Real” Capacity

Don’t trust the “Max Capacity” on the sticker. That’s for water. Here is the real-world throughput when processing raw chicken carcasses or fish frames.

Model Real Capacity (kg/h) Power (kW) Dimensions (mm) Best Used For
GN-200 100-200 5.5 780×500×1250 Small Batches / R&D Labs
GN-300 600-1200 15 1020×560×1380 SME Factories (Most Popular)
GN-300T 1000-2000 18.5 1500×700×1480 Continuous Sausage Lines
GN-500 2500-3500 37 2010×980×2300 Large Scale Industrial Plants

The Efficiency Trap: Competitors will promise you 5 tons/hour. But in reality, when processing frozen chicken frames (-4°C), their efficiency drops by half. The GN-500 is geared with high-torque motors that maintain 85% efficiency even with semi-frozen loads. In a double-shift plant, that’s an extra 5 tons of output per month compared to standard mills.

 

Applications: Where to Use Bone Mud?

  • Bakso & Meatballs:Replace 20-30% of lean meat with chicken bone paste. It lowers cost significantly while adding natural calcium.
  • Instant Noodle Soup Base (Pho/Ramen):Grind the bones to a paste before You extract flavor in 40 minutes instead of boiling whole bones for 12 hours. Energy savings are massive.
  • Pet Food:Produce high-calcium raw diets (BARF) with zero thermal degradation—this is a booming market in Thailand and Vietnam right now.

 

❓ FAQ: Straight Answers to Tough Questions

Q: Can this machine grind beef bones?A: Yes, but with a condition. Fresh beef bones must be crushed to <50mm (using a bone crusher) before entering the GN machine. If you throw in a whole cow femur, you will break the machine. For chicken and fish, you can feed whole frames.

Q: How often do I need to change the grinding head?A: This depends on your material. If you run chicken skeletons 8 hours a day, the German carbide head lasts about 1.5years. If you run harder pork bones, expect 0.5 years. Compare that to standard steel heads that lose sharpness in 3 months—that’s the difference in TCO (Total Cost of Ownership).

Q: Will the bone paste taste “metallic”?A: Absolutely not. The grinding head is Tungsten Carbide, and the chamber is SUS304. There is no iron oxidation. The paste tastes exactly like the raw material.

Q: Do you support 220V single phase?A: For the GN-200, yes. But for the GN-300 and above, you must use 380V 3-phase. You cannot get the torque required to crush bone with single-phase power. Don’t let anyone tell you otherwise.
