Customized Blades

The Core Application Of Irregular Blades In The Food Industry

Alien blades in the food industry have a wide range of applications in pre packaged food and meat processing, baking and packaging slitting, and special ingredient processing, as follows:

1.Complex ingredient cutting: The irregular blade can accurately cut irregular ingredients such as chicken feet and fish fins through customized blade design (such as curved blade, wavy blade), and can adapt to various processing needs of a single machine, improving the efficiency of processing pre made food ingredients.

2.Adaptation to automated production lines: Combined with a hanging chain conveyor system, the shaped blades can complete the fine decomposition of chicken and duck bodies (such as bone removal and wing separation), with a processing capacity of 800-1000 per hour on a single production line.

3.Baking food cutting: Using serrated shaped blades to cut cakes and puff pastry, avoiding squeezing and deformation, with a cutting flatness error of ≤ 0.2mm, ensuring the appearance quality of high-end baked goods. Customized low-temperature anti sticking blades (-10 ℃ working environment) for frozen dough to reduce the rate of food adhesion and damage.

4.Food packaging processing: Alien blades are used for cutting packaging materials such as aluminum foil and composite film, with a micrometer level precision (± 0.0005mm) at the cutting edge to achieve burr free cutting, suitable for synchronous operation of high-speed sealing machines. The dotted blade completes the easy to tear line processing on the snack packaging bag, and the cutting depth is precisely controlled to be 1/3-1/2 of the material thickness.

5.Processing of dairy and soy products: Cheese cutting uses a constant temperature shaped blade (10-15 ℃), combined with an obtuse angle blade design, to achieve 0.2-1.0mm thin slice cutting without residual debris. In the irregular cutting of soft food materials such as tofu and dried tofu, hydrophobic coating is added on the blade surface to reduce the attachment rate of food materials by ≥ 40%.

Alien blades, through non-standard customization and material innovation, improve food processing accuracy while reducing loss rates, becoming a core tool in the fields of pre packaged food, packaging, and special ingredient processing.

Material Type	Applicable Scenario	Performance Advantage	Typical Parameters
301 Stainless Steel	Cutting of fruits and vegetables and packaging film	Low cost and easy maintenance	Hardness HRC50-53
4cr13 Stainless Steel	Meat, baking and cutting	Wear resistance increased by 30%	Hardness HRC54-56
High-Speed Steel	High speed cutting of frozen meat and composite film	Thermal collapse edge	Hardness HRC62-64
Hard Metal	Treatment of bones and superhard ingredients	Life span ≥ 8,000 hours	Hardness HRC88-92

The food industry's irregular blades achieve full scene coverage from conventional cutting to high-strength processing through precise matching of materials and processes.

1.301/302 stainless steel: suitable for basic cutting scenarios, corrosion resistance meets food contact standards, hardness range HRC50-53.

2.3Cr13/4Cr13 martensitic stainless steel: The wear resistance is improved through heat treatment process, and the hardness can reach HRC54-56, suitable for meat cutting and packaging material cutting.

3.304/440C stainless steel: Made of high-purity material (with a carbon content of 0.9% -1.2%) that balances corrosion resistance and sharpness, it is used for precision processing of dairy products, baked goods, and other products.

4.White steel (such as W6Mo5Cr4V2) has a hardness of HRC62-64 and is used in high load cutting scenarios (such as frozen meat and composite film cutting) with outstanding anti chipping performance. Some blades are coated with high-speed steel alloy to improve the heat resistance of the blade edge (working temperature tolerance ≤ 300 ℃).

5.Hard alloy (tungsten steel): made by sintering tungsten carbide and cobalt, with a hardness of HRC88-92, used for cutting superhard food (such as bones and frozen food), with a wear resistance life 5-8 times that of ordinary steel.

Coating strengthening

Titanium based coating (TiN/TiAlN) reduces the friction coefficient by 30% -40%, reduces food adhesion, and is suitable for soft and sticky foods such as soy products and cheese.

Chromium nitride coating (CrN) enhances corrosion resistance and meets the requirements of CIP cleaning and high-temperature steam disinfection.

Special processing techniques

Laser micro level cutting technology: blade roughness ≤ Ra0.2 μ m, achieving burr free cutting (such as aluminum foil packaging materials).

Low temperature tempering process: Balancing hardness and toughness to prevent blade fracture under impact loads (such as pork rib cutting scenarios).

Wave Blade	The cutting edge is wavy	High-frequency meat grinder and vegetable shredding device for reducing food adhesion and improving cutting efficiency

Meat processing

Chopping and mixing machine: using a combination of curved and straight knives to achieve emulsification and mixing of minced meat.

Meat grinder: Irregular blades (such as nine shaped blades) are suitable for adjusting the thickness of different meats.

Baking and Frozen Products

Bread slicer: serrated shaped blade (such as stainless steel bread knife) ensures a smooth cut surface.

Frozen meat cutting machine: Hard alloy blades (such as V-shaped blades) are suitable for efficient cutting of frozen meat.

 

Selection principle

High frequency scenario: Prioritize hard alloy or titanium coated blades for better wear resistance.

Special requirements: Customization of blade density and outer diameter is required (such as customized aperture for mesh blades).

Maintain standards

Cleaning requirements: Rinse blood stains or food residue immediately after use to avoid corrosion (stainless steel blades need to be thoroughly cleaned weekly).

Replacement cycle: It is recommended to replace the blades every 200-300 hours for commercial high-intensity operations, and it can be extended to 1 year for household devices.

Irregular blades in the food industry are made of stainless steel materials (such as 420J2) and customized blade designs (curved blades, U-shaped blades, wavy blades) as the core, suitable for diverse scenarios such as chopping, meat grinding, and slicing. Mainstream manufacturers meet industrial and household needs through enhanced processes (vacuum heat treatment) and functional design (anti adhesion structure).
