The Newin 300T is a 12-inch semi-automatic commercial meat slicer designed for butcher shops, supermarkets, restaurants, hot pot kitchens, delis and other commercial food preparation environments. It uses a 300mm blade, a 450W copper-core motor and an adjustable slicing thickness system for different meat preparation requirements.
The machine has a full stainless steel body and a built-in safety sharpening device. Its 300mm blade provides a larger cutting area than smaller commercial slicers, while the semi-automatic design keeps the operation straightforward for regular meat slicing work.
For businesses comparing different blade sizes, the 300T sits between smaller 8-inch and 10-inch semi-automatic models and larger 14-inch machines. This makes it a practical option when a 12-inch blade is preferred for daily commercial meat preparation.

300mm / 12-Inch Slicing Blade
The 300T uses a 300mm diameter slicing blade, giving the machine a 12-inch cutting format suitable for commercial meat preparation. The specified mutton cutting size is Ø140mm, while the rectangular cutting size is 210 × 140mm.
The larger blade format is useful for businesses that regularly prepare larger portions of meat and want a commercial slicer positioned above compact 8-inch and 10-inch models.
For smaller operations that do not need a 12-inch blade, the 220T 8-inch semi-automatic commercial meat slicer and 250T 10-inch semi-automatic commercial meat slicer provide smaller blade options within the same product range.
Semi-Automatic Slicing Operation
The 300T is designed as a semi-automatic commercial meat slicer. It combines powered blade operation with operator-controlled meat positioning, making it suitable for businesses that need a straightforward slicing machine without moving to a larger fully automatic system.
This configuration can be used for routine meat preparation in butcher shops, supermarket counters, restaurant kitchens and other commercial food-service environments where operators need to adjust the slicing process according to the product being prepared.


Full Stainless Steel Body
The 300T features a full stainless steel body designed for commercial food preparation environments. The stainless steel construction provides a practical machine surface for regular cleaning and helps keep the working area organized during daily operation.
After processing, meat residue should be removed from the blade area and other accessible working surfaces. The machine should be cleaned and dried according to the supplied operating instructions.
Built-in Safety Sharpening Device
A built-in safety sharpening device is included with the 300T. Keeping the slicing blade in suitable condition is important for maintaining consistent cutting performance during normal operation.
The integrated sharpening arrangement also keeps the sharpening function with the machine instead of requiring a separate sharpening setup. Operators should follow the manufacturer’s instructions when sharpening or handling the blade.
Adjustable Slicing Thickness
The 300T provides adjustable slicing thickness, allowing operators to select the desired slice setting according to the meat product and preparation requirements.
Different applications may require different slice thicknesses. For example, retail meat counters, restaurant kitchens and hot pot preparation may use different cutting settings depending on the product being prepared.
The exact operating setting should be selected according to the meat type, product size and required finished slice.
450W Copper-Core Motor
The 300T is equipped with a 450W copper-core motor for powered slicing operation. The rated input power is 450W, with a rated voltage of 220–240V and a rated frequency of 50Hz.
For commercial buyers, the electrical specification should be checked against the power supply available at the installation site before ordering. Voltage requirements can also be confirmed with Newin when discussing an order.
Cutting Size
The specified mutton cutting size for the 300T is Ø140mm. The rectangular cutting size is 210 × 140mm.
These dimensions are useful when checking whether the machine’s cutting area matches the size of the meat rolls or portions used in your production process. Buyers should compare the actual product dimensions with the machine’s specified cutting size before selecting the model.
Suitable Applications
The Newin 300T can be considered for a range of commercial meat preparation applications, including:
- Butcher shops and meat counters
- Supermarket meat departments
- Restaurant and hotel kitchens
- Hot pot restaurants
- Delis and food-service businesses
- Catering and central kitchen preparation
- Small and medium commercial meat processing operations
The best application depends on the required cutting format, meat size, daily workload and available electrical supply.
Choosing the 300T for Your Application
The 300T is a suitable model to consider when a commercial operation needs a 12-inch semi-automatic meat slicer with a 300mm blade and 450W motor.
If blade diameter is the main selection factor, Newin’s semi-automatic slicer range provides several sizes. The 220T uses an 8-inch blade, the 250T uses a 10-inch blade, while the 300T uses a 12-inch blade. Businesses requiring a larger 14-inch semi-automatic format can also compare the 360T 14-inch semi-automatic commercial meat slicer.
For applications that require automatic rather than semi-automatic operation, a different product family may be more appropriate. For example, the 300KR 12-inch automatic frozen meat slicer is positioned for automatic frozen meat slicing.
Installation and Power Supply
Before installation, make sure the machine is placed on a stable working surface with enough surrounding space for operation, cleaning and routine maintenance.
The rated electrical specification of the 300T is 220–240V / 50Hz with a 450W input power. Confirm that the local power supply matches the machine specification before operation.
The machine dimensions are 560 × 530 × 570mm, so buyers should also check the available installation space before ordering. The package dimensions are 650 × 550 × 455mm for shipping and handling reference.


🛠️ Maintenance Tips
- Clean meat residue from the cutting area after each use.
- Clean and dry the cutting components after washing.
- Check the knife condition regularly and maintain or replace the cutting components when necessary.
