VERFOODSOLUTIONS Preduster Flouring Machine with Air Flow System Delivered to Italy for French Fries Production

Recently, our Italian customer, who ordered a French fry processing line, made a repeat purchase.

Previously, the customer purchased a washing and peeling machine, a slicing and dicing machine, a blanching machine, a water cooling machine, and an air cooling machine. This time, they ordered a 600mm preduster flouring machine, which has now been manufactured and shipped. The customer uses this machine to process various potato products, such as 10×20 mm and 15×15 mm French fries, as well as 25×25 mm potato cubes.

The production process begins with the previous equipment, where potatoes are blanched and washed using salt water to remove surface starch. Afterward, they are drained and coated with flour. Applying flour before frying helps lock in moisture, facilitating the formation of a crispy crust during frying. This process also quickly sets the shape, enhances crispiness, and promotes more even flavor absorption.

In addition to the preduster flouring machine, the customer also ordered an air flow system to be used in conjunction with it. This system serves two key purposes: first, it helps remove dust, preventing airborne particles and maintaining a cleaner working environment; second, it blows away excess loose flour from the products, ensuring a smoother subsequent processing stage.

Next, let’s take a closer look at the 600mm preduster flouring machine and its airflow system.

1. Customized Feed Inlet Height  

The preduster flouring machine is designed to seamlessly integrate with the potato washing, blanching, and drying line. To facilitate a smooth connection, we have engineered the feed inlet height to be 750 mm. This height ensures that the machine aligns perfectly with the production line, allowing for efficient material transfer and streamlined operation.

2. Control Panel  

The preduster flouring machine is equipped with a user-friendly control panel, entirely in English, ensuring easy operation and precise control.

3. Flour Feeding Port  

The preduster flouring machine’s flour feeding port is fitted with an auger that thoroughly breaks up the flour during application. This prevents clumping and results in a more even, fine coating.  

Additionally, it features a protective mesh cover to ensure operator safety. The outer sealed cover prevents dust from escaping, maintaining a clean and tidy working environment.

4. Rollers

The preduster flouring machine features rollers that apply continuous pressure to the flour, gently pressing it onto the surface of the product. The rollers rotate synchronously with the passing products, ensuring even flour distribution and strong adhesion. This precise process helps prevent over- or under-coating, resulting in a uniform and consistent coating every time.

5. Dual-Belt System  

The preduster flouring machine employs a unique dual-belt system to ensure a consistent and uniform coating. The product is fed onto the lower conveyor belt, which passes through the material bed, while the upper conveyor applies a precise “spreading” spray from above. Together, these belts work in harmony to achieve an even coating. The dual-belt design minimizes material backflow and dust generation, promoting a clean, hygienic, and efficient working environment.

6. Adjustable Flouring Coating Thickness

The preduster flouring machine features an adjustable coating thickness, controlled by an internal baffle operated via a side handle. Raising the baffle allows more flour to fall, resulting in a thicker predust coating, while lowering it reduces flour flow for a thinner coating. This adjustable mechanism enables precise control over the coating thickness, ensuring optimal product appearance and flavor.

The entire adjustment process is clearly visible through the side viewing window, allowing operators to monitor and make real-time adjustments. Additionally, the handle can be secured in place with a nut for stable operation.

7. Vibrating Blocks  

The conveyor belt of the preduster flouring machine is equipped with vibrating blocks. Once the machine is operational, these blocks vibrate to remove any loose flour from the coated products as they pass through. This process ensures a thin, even coating, which is beneficial for achieving consistent quality in subsequent processing steps.

8. Safety Contact Switch  

The flour circulation column of the preduster flouring machine is designed with a safety contact switch. If the circulation column door is not properly closed, the machine will not power on, providing an essential safety feature to protect operators during operation.

9. Air Flow System  

When the product passes through the preduster flouring machine, some flour residue may remain after coating. To prevent loose flour from contaminating subsequent processing stages, an air flow system is installed. This system blows away any loose flour from the product surface, leaving only the flour that is firmly adhered. The residual flour absorbs moisture from the product surface, which is beneficial for subsequent baking and breading processes.

The blown-off dust is separated from the airflow using an advanced cyclone separator, effectively removing dust particles from the environment. The collected dust is stored in a dust collector’s bin, which can be emptied after operation for reuse. This design maintains a clean working environment and helps conserve flour, reducing waste.

10. Air Flow Pipeline  

The air flow system operates as a standalone unit that must be connected to the preduster flouring machine to achieve effective dust removal. The preduster flouring machine is designed with multiple airflow pipelines and outlets to enhance dust extraction efficiency.

Connecting the air flow system to the preduster flouring machine is straightforward: simply insert the pipes into their corresponding connections and secure them in place. Detailed instructional videos are provided below to assist with the setup.

11. Motor Protective Cover  

The motor of the air flow system is positioned on top of the machine. To ensure safety and protection, a motor protective cover is installed. The cover features a circular handle on top; loosening the clips allows you to lift the cover using the handle, providing access to the entire air flow system, including the motor, for maintenance or inspection.

12. Adjustable Casters

Both the preduster flouring machine and the air flow system are equipped with highly adjustable casters for easy repositioning. On uneven surfaces, the casters can be adjusted within a range of 10 cm to ensure the machines operate on a level surface, enhancing stability and safety during operation.

13. Stainless Steel Construction  

The entire preduster flouring machine and air flow system are constructed from 304 stainless steel. This material is not only aesthetically pleasing with a glossy finish but also highly durable, rust-proof, and corrosion-resistant. It will not deform over time, significantly extending the equipment’s service life.

14. Accessories

When you purchase a preduster flouring machine, we include essential accessories at no additional cost to ensure smooth and reliable operation. These complimentary accessories include a stainless steel conveyor belt, switch buttons, safety contact devices, air flow system ducts, clasps, and other necessary components. Designed for durability and long-term use, these accessories help you maximize the machine’s performance and maintain efficient production over time.

As essential components in the French fry manufacturing process, the preduster flouring machine and air flow system are vital for achieving the perfect crispy texture and enhancing flavor through the Maillard reaction. Their precise coating and dust removal capabilities ensure consistent product quality, improve processing efficiency, and contribute to a more appealing final product that meets consumer expectations.
