FMG-100 Series Industrial High-Efficiency Frozen Meat Grinder / Heavy-Duty Mincer - Technical Specifications & Operation Manual

FMG-100 Series Industrial High-Efficiency Frozen Meat Grinder

I. Product Overview

1. Basic Equipment Information

  • Equipment Name: High Efficiency Industrial Frozen Meat Mincer Meat Grinder
  • Product Series & Models: FMG Series (Standard baseline model: FMG-100; high-capacity options: FMG-120, FMG-130, and FMG-160)
  • Equipment Type: Floor-Standing Heavy-Duty Industrial Dual-Use Frozen & Fresh Meat Grinder
  • Industry Positioning: Solves three major operational bottlenecks in commercial meat processing: long thawing times, drip loss of nutritious meat juices, and frequent motor stalling/burnout in standard grinders. Extensively utilized in sausage and ham production, meatball and patty processing lines, frozen dumpling/bun filling preparation, central kitchen fresh portioning networks, and raw pet food manufacturing.

Construction & Engineering Highlights:

  • Food-Grade 304 Heavy-Gauge Stainless Steel Body: The housing and all contact surfaces are constructed from seamless-welded food-grade stainless steel with a brushed finish, offering resistance to acid, alkali, and brine corrosion while easily withstanding high-pressure washdowns.
  • Deep High-Capacity Gravity-Fed Hopper: Engineered with an angled feed chute that allows entire boxes of tempered or frozen meat chunks to be dumped directly into the hopper. Gravity combined with auger traction ensures continuous, smooth intake without splashing or bridging.
  • Heavy-Duty Anti-Vibration Base: Engineered with a low center of gravity and height-adjustable vibration-dampening feet to maintain smooth, low-noise, and stable operation even during high-torque shearing of rock-hard frozen blocks.

2. Core Functions & Working Principle

The FMG series utilizes a high-power three-phase industrial motor coupled with a heavy-duty reduction gearbox to drive an alloy feed screw auger at calibrated speeds:

  • No-Thaw Power Feed & Shearing: When frozen raw materials (meat blocks, trim sheets, poultry cartilage, etc.) enter the hopper, the heavy-duty screw auger applies progressive compression, forcefully propelling the meat forward.
  • Instantaneous Precision Orifice Cutting: As meat reaches the discharge head, high-speed rotating hardened-alloy cross blades work against precision-machined perforated plates (grinding dies) to generate shearing force, cutting the meat into uniform particles before extruding them cleanly.
  • Low-Temperature Rise Preservation: Thanks to the short cutting path and rapid extrusion cycle, frictional heat generation inside the barrel is minimal. This prevents fat smearing and protein denaturing, preserving natural meat coloration, texture, and bind.

3. Core Value: Why Choose the FMG Series?

  • Eliminate Lengthy Thawing & Prevent Drip Loss: Conventional thawing consumes cold-storage energy, takes up valuable floor space, and results in 3%–5% purge/drip loss. The FMG-100 grinds frozen meat directly, optimizing yield and nutrient retention.
  • 500 to 3,000 kg/h Industrial-Scale Output: The entry-level FMG-100 delivers 500–800 kg/h, while the top-tier FMG-160 exceeds 3,000 kg/h, effortlessly supporting continuous automated processing lines.
  • Customizable Coarseness via Interchangeable Plates: With standard and optional orifice plates ranging from φ4 mm to φ30 mm, operators can switch from fine emulsion prep (emulsified sausages, smooth meatballs) to coarse grinds (burger patties, coarse salamis) simply by swapping plates.

II. Production Workflow & Standard Operating Procedure (SOP)

To maintain consistent high-load operation and ensure factory floor safety, strictly adhere to the following standard operating procedures:

1. Ingredient Preparation & Pre-Treatment

  • Raw Material Standards:
  • Frozen Meats: Ideal product temperature ranges between -18°C and -2°C (pork, beef, mutton, deboned poultry, etc.).
  • Fresh Meats & By-Products: Chilled aged meats, frozen fat trimmings, pork rinds, soft poultry frames/carcasses (e.g., chicken backs/necks), and dehydrated root vegetables.
  • Input Sizing: Oversized frozen meat blocks should be pre-portioned using a frozen meat block flaker or bone saw to fit the hopper intake (recommended block size: within 10 × 10 × 15 cm). Never feed uncrushable dense bones (such as whole beef or pork femur bones) into the unit.

2. Pre-Start Inspection & Electrical Verification

  1. Verify that the unit is connected to an industrial 380V 3-phase AC power supply by a certified electrician, with reliable electrical grounding.
  2. Ensure the front locking collar (retaining ring) is tightened securely so the cross blade sits flush against the hole plate without binding.
  3. Momentarily jog the start button to check the rotation direction of the auger against the directional indicator arrow on the machine (reverse rotation will damage the cutter and auger).
  4. Run the machine empty for 1–2 minutes to confirm smooth gearbox operation with no abnormal friction, noise, or overheating.

3. Continuous Feeding & Grinding Operations

  1. Place a stainless steel meat cart or transfer conveyor directly under the discharge port.
  2. Press the green start button and let the motor reach full operational speed.
  3. Feed the prepared frozen meat blocks steadily and continuously into the hopper.
  4. Safety Protocol: The machine is self-feeding via gravity and auger pull. Never use metal shovels, iron hooks, or bare hands to push meat into the throat of the hopper. If necessary, use only the dedicated food-grade plastic safety plunger.
  5. Monitor output extrusion to maintain continuous, unobstructed discharge.

4. Changing Cutter Blades & Grinding Plates

  1. Always shut down, disconnect power, and execute Lockout/Tagout (LOTO) before replacing tooling.
  2. Unscrew the front locking ring counter-clockwise, then remove the perforated plate and cross knife in sequence.
  3. Install the desired plate (e.g., changing from 6 mm to 12 mm): First place the cross knife onto the square drive shaft (cutting edges facing outward toward the plate), align the plate pin with the keyway on the housing, and slide the plate into place.
  4. Hand-tighten the retaining ring clockwise until snug, verifying that the assembly seats squarely without over-tightening.

5. Post-Shift Sanitation, Teardown & Maintenance

  • At the end of every operating shift, turn off the main breaker and disconnect the power supply.
  • Remove the retaining ring, orifice plate, cross knife, and feed screw auger.
  • Rinse the hopper, barrel, and all disassembled components with warm water; scrub thoroughly using a food-grade foaming alkaline detergent, followed by sanitization.
  • Dry all parts completely. Apply a food-safe protective coating of white mineral oil or vegetable oil to the auger splines, knives, and hole plates to prevent surface oxidation.

IV. Frequently Asked Questions (FAQ)

  • Q: Can the FMG series really grind frozen meat blocks directly without thawing? Will it stall the motor or break the blades?
  • A: Yes. The FMG series is built specifically for frozen product processing. Featuring 5.5 kW to 15 kW high-torque motors, industrial-grade reduction gearboxes, and deep-fluted variable-pitch screw augers, it generates massive feeding and crushing force. Coupled with heat-treated alloy cross blades, as long as the material falls within normal frozen parameters (-18°C to -2°C) and fits into the hopper opening, it shears and extrudes immediately without jamming or overloading the motor.
  • Q: Why is "minimal temperature rise" critical during high-speed frozen meat grinding? How does it impact product quality?
  • A: Proteins and fats in meat are sensitive to thermal exposure. Significant friction-induced heat during grinding can melt fat, cause discoloration, and break down protein fibers, leading to rubbery texture loss in meatballs and fat separation/greasiness in sausages. The FMG series features optimized auger flighting and discharge flow paths that ensure short residence times, limiting temperature rise to just 1–2°C and keeping the muscle fiber network and natural binding properties intact.
  • Q: Can this machine also handle fresh meat, soft bone poultry frames, or vegetables?
  • A: Absolutely. The unit is fully dual-purpose for both frozen and fresh ingredients. In addition to hard-frozen meat, it efficiently processes chilled fresh meat, poultry carcasses with soft bones (e.g., chicken backs), pork rind, beef fat, and aromatics such as ginger, garlic, and chili peppers, making it an adaptable solution for food manufacturing plants.
