Optimize your biscuit production with Bellaex food-grade biscuit rollers. We offer custom CNC engraving for rotary moulds, durable sheeting rolls, and cookie dough rollers with anti-stick coating. Precision engineered for OEMs and factories.
Product Overview
Precision Engineered Mill Rollers for the Grain Industry
Content Paragraph: Shandong Zibo Jintai Roll Co., Ltd (Bellaex) combines decades of metallurgical expertise with advanced CNC engraving technology to produce biscuit dough rollers that perform flawlessly under continuous industrial operation. We don't just supply metal cylinders; we provide engineered surfaces that optimize dough rheology and release properties.
Our product range covers the critical stages of the biscuit forming line:

Q: Can Bellaex manufacture custom biscuit moulds based on a sample or photo?
A: Yes. We specialize in custom biscuit roller design. If you do not have the original CAD drawings, our engineering team can reverse-engineer your existing roll or biscuit sample to create a precise digital model. We use high-precision CNC engraving to ensure the replicated pattern matches your product specifications perfectly.
Q: What materials do you use to ensure food safety?
A: Hygiene is our top priority. We manufacture food-grade biscuit rollers using certified materials such as high-quality Carbon Steel (45#), Alloy Steel, or Lead-free Bronze for rotary moulds. All rolls can be supplied with specific surface treatments (e.g., hard chrome plating or specialized non-stick coatings) to meet international food contact standards.
Q: Are your rolls compatible with major biscuit machinery brands?
A: Absolutely. Bellaex manufactures replacement rolls that are fully compatible with equipment from major global manufacturers. We strictly adhere to OEM tolerances for bearing fits and gear locations to ensure a seamless installation.
Q: Do you offer re-engraving or repair services for worn rollers?
A: Yes, for valuable bronze rotary moulds, we often provide re-engraving services to restore the pattern definition, extending the roller's lifespan and saving you replacement costs. Please contact our technical team to assess if your roller is suitable for refurbishment.
Q: How do you package heavy rollers for international shipping?
A: To prevent damage and corrosion during sea freight, all biscuit rollers are coated with food-safe anti-rust oil and wrapped in moisture-proof barriers. They are then secured in fumigation-free wooden crates designed to withstand impact, ensuring they arrive at your factory in perfect condition.
Material & Manufacturing
Content: At Bellaex, we understand that a biscuit roller is more than just a machine part—it is a food-contact surface that requires strict hygiene and metallurgical stability. We control every variable in the manufacturing process to ensure premium quality.
We strictly utilize certified food-grade materials to ensure safety and compliance:
Unlike traditional casting methods that may lack definition, our rotary moulds are processed using multi-axis CNC engraving centers. This digital manufacturing process ensures:
To solve the common headache of "dough sticking," we offer specialized surface treatments including Hard Chrome Plating and PTFE (Teflon) Coatings. These finishes create an ultra-smooth, non-porous surface that allows for easy cleaning and effortless dough release, even with sticky high-sugar formulations.

Key Features
Why Leading Bakeries Choose Bellaex Biscuit Rollers
In industrial baking, even a 1-gram deviation per biscuit adds up to significant raw material loss over a year. Bellaex utilizes high-precision CNC engraving to ensure every mould cavity has identical volume.
The Benefit: You achieve strict dough weight consistency, reducing "giveaway" (overweight products) and ensuring uniform baking color and texture.

Sticky dough leads to machine downtime and deformed products. Our rolls feature advanced surface treatments, including Hard Chrome Plating and Food-Grade PTFE (Teflon) coatings, tailored to your specific dough moisture and sugar content.
The Benefit: Drastically reduces production stoppages for cleaning and ensures perfectly shaped biscuits, even with difficult, sticky formulations.
Standard steel rolls wear out quickly under the friction of abrasive ingredients (like whole grains or sugar crystals). Bellaex employs Chilled Cast Iron and wear-resistant Alloy Steel with superior surface hardness (up to HS 75).
The Benefit: Our rolls maintain their pattern definition longer, extending the replacement interval and lowering your Total Cost of Ownership (TCO).
Running an older line without original drawings? No problem. We can reverse-engineer your existing worn-out roller or simply take a physical biscuit sample to recreate the exact mould design digitally.
The Benefit: You get a drop-in replacement that fits your existing bearing housings and drive gears perfectly, eliminating the need for expensive machine modifications.
