1. What is a professional meat mincer?
A professional meat mincer is a machine designed to:
-
process large quantities of meat (from 100 to 1000+ kg/h)
-
operate continuously
-
maintain strict hygiene standards
-
allow fast disassembly and cleaning
-
use standardized plates and knives
It consists of:
- grinding unit → housing + auger + knife + plate
- cutting system
- auger (screw) → the spiral mechanism that feeds the meat forward
- plates → the perforated grinding discs
- knives
- reducer (gearbox) → reduces motor speed and increases torque
- motor
- hopper → the upper tray for meat
- body (frame)

2. Grinding unit — aluminium or stainless steel?
This is the most important choice after motor power.
Aluminium grinding unit
| ✔ lighter | ❌ cannot be washed in a dishwasher |
| ✔ cheaper | ❌ does not support the Unger system |
| ✔ suitable for standard workloads | ❌ less durable under intensive use |
Stainless steel grinding unit (AISI 304)
| ✔ highest hygiene | ❌ higher price |
| ✔ dishwasher‑safe | |
| ✔ more durable under heavy load | |
| ✔ supports the Unger system | |
| ✔ longer lifespan |
Recommendation:
- For butcher shops, supermarkets and production facilities → stainless steel
- For restaurants and medium workloads → aluminium
3. Cutting systems: Enterprise vs Unger
This is the internal assembly of knives and plates.

Enterprise system (standard)
1 knife + 1 plate
-
faster
-
easier to clean
-
standard on all machines
-
ideal for minced meat, kebab, kofta, burgers
Unger system (optional – only for stainless steel grinding units)
A multi‑component system (multiple knives + multiple plates):
-
finer grinding
-
more uniform texture
-
lower meat temperature
-
ideal for sausages, cured meats, delicatessen products
Important: The Unger system is NOT available for aluminium grinding units.
4. Meat mincer numbering
This is an international standard based on the diameter of the grinding plate.
| Mincer Number | Plate Diameter (approx.) | Suitable For |
|---|---|---|
| No.12 | ~70–82 mm | small kitchens, restaurants |
| No.22 | ~82–86 mm | medium‑size operations |
| No.32 | ~98–114 mm | butcher shops, supermarkets |
| No.42 | ~130 mm | production facilities |
The higher the number → the larger the plate diameter → the higher the throughput and the more powerful the machine.
The gold standard for professional use: #32
5. Motor power and performance
1.6 kW (300–500 kg/h)
Suitable for:
-
restaurants
-
small butcher shops
-
supermarkets with moderate workload
2.2 kW (300–500 kg/h, but more durable)
Suitable for:
-
butcher shops
-
supermarkets
-
small production facilities
-
intensive daily operation
3+ kW (500–1200 kg/h)
Suitable for:
-
industrial production
5.1 Single‑phase vs three‑phase machines — what should you choose?
It is important to understand that single‑phase and three‑phase meat mincers may have the same nominal power (watts), but they operate very differently. A three‑phase motor delivers power more evenly, has a higher starting torque, and works more stably under load. This allows the machine to run longer, quieter and with less heat build‑up — even when the wattage is identical.
This is a critical factor that customers often misunderstand.
Single‑phase (230V)
Suitable for:
-
restaurants
-
small kitchens
-
home use
-
locations without three‑phase power
Characteristics:
-
lower power
-
easier installation
-
lower price
-
less durable for continuous operation
Three‑phase (400V)
Suitable for:
-
butcher shops
-
supermarkets
-
production facilities
-
high‑load environments
Characteristics of three‑phase machines:
-
not higher wattage, but more stable power delivery
-
higher starting torque
-
smoother operation without power drops
-
quieter
-
longer motor lifespan
-
less overheating during prolonged use
6. Construction and materials
6.1 Body and hopper (top tray for meat)
Always choose stainless steel:
-
easier to clean
-
higher hygiene
-
longer lifespan
6.2 Gearbox (reducer)
The gearbox is the mechanical component that converts the motor’s high RPM into a slow but extremely powerful rotation of the auger. This allows the mincer to operate smoothly, without vibration or stalling — even when processing tougher cuts of meat.
Machines with an oil‑bath gearbox are:
-
quieter
-
more reliable
-
more durable
Avoid dry gearboxes.
Note on the auger (screw)
The auger is the spiral mechanism inside the grinding unit that pushes the meat toward the knife and plate. It ensures:
-
consistent feed
-
stable pressure
-
continuous grinding
The more massive and precisely machined the auger, the more stable and efficient the machine.
6.3 Cooling
A cooling fan is essential for intensive operation.
6.4 Safety features
-
micro‑switches
-
overload protection
-
reverse function
7. Plates and grids
| Size | Usege |
|---|---|
| 3–4 mm | fine grinding, pates |
| 6 mm | standard minced meat |
| 8 mm | coarser minced meat |
| 10–12 mm | sausages |
| 14–16 mm | coarse grinding, chorizo |
| 20+ mm | specialties |
8. Refrigerated meat mincers
Refrigerated meat mincers are a higher‑class category of professional machines designed for environments where meat stays in the hopper for longer periods or where the machine operates continuously. They have an integrated cooling system that keeps the temperature of the grinding unit and hopper within safe limits.
✔ What do they cool?
-
the grinding unit
-
the hopper
-
the housing around the auger
✔ Why is this important?
-
prevents bacterial growth
-
preserves the structure and quality of the meat
-
allows continuous operation
-
ideal for supermarkets, display counters and production facilities
✔ Examples
Here you can explore refrigerated mincer models No.22 and No.32, suitable for supermarkets and stores with a constant customer flow.
✔ When should you choose a refrigerated meat mincer?
-
when operating for more than 3–4 hours without interruption
-
when selling directly from a display counter
-
when high hygiene standards are required
-
when processing large quantities of meat
✔ When is it NOT needed?
-
restaurants
-
kitchens
-
butcher shops with portion‑based work
-
businesses that grind meat on demand
9. Semi‑professional meat mincers (Lacor)
These models are suitable for:
-
small restaurants
-
home kitchens
-
light workloads
Characteristics:
-
smaller grinding units
-
weaker motors
-
shorter duty cycles
-
not suitable for butcher shops or supermarkets

10. How to choose the right model?
Restaurant → No.12 or No.22, 1.6 kW
Butcher shop → No.32, 1.6–2.2 kW, stainless steel grinding unit
Supermarket → No.32, 2.2 kW, stainless steel + Unger system
Production facility → No.42, 3+ kW, stainless steel, Unger system
