Strayfield's RF dryers for quality throughout and enhanced productivity of baked products

When it comes to drying baked products after they come out of the oven, Radio Frequency (RF) drying is a game-changer. By utilizing electromagnetic energy to generate heat directly within the products, RF drying offers efficient and speedy drying, resulting in baked goods of superior quality.

RF drying brings a host of advantages that make it the ideal choice for high-volume production environments. Firstly, it significantly reduces drying times compared to other methods, allowing for faster production cycles and increased output without compromising on the quality of your baked products.

One of the key benefits of RF drying is its gentle process. The quick completion time minimizes the risk of over-drying or heat damage, preserving the integrity and flavour of the baked goods. Additionally, RF drying ensures uniform drying throughout the batch and throughout the width of the conveyor belt, eliminating issues such as under-dried or over-dried areas. This means you can consistently deliver top-notch baked products to your customers.

In addition to its efficiency, RF drying is an energy-saving solution. By generating heat directly within the products, it minimizes energy consumption compared to traditional drying methods that rely on heating the air or other mediums. This not only benefits your business economically but also contributes to sustainability efforts.

Upgrade your post-baking process by investing in Strayfield’s RF drying equipment and experience the benefits it brings to your production line. With RF drying, you can efficiently dry your baked products while maintaining their quality, enhancing productivity, and reducing energy consumption.

FAQs for our RF dryers

How does RF drying technology eliminate product cracking and checking?

RF drying technology utilizes controlled and uniform heating throughout the product, reducing the formation of moisture gradients that cause cracking and checking. This ensures that the product dries evenly, minimizing the risk of surface defects.

What are the benefits of moisture profiling through the product cross-section?
Moisture profiling allows for uniform quality and improved shelf life.
How can Strayfield RF Drying Machines increase the productivity of preinstalled ovens?
Strayfield RF Drying Machines can increase the productivity of preinstalled ovens by up to 40%. The efficient RF drying process reduces overall drying time and lowers energy costs, allowing for faster throughput and increased production capacity. Since heat is generated directly within the baked product when it is exposed to RF energy, there is no reliance on the temperature, thermal properties, or case hardening effects of the baked product or oven to heat and eventually dry the product.
What impact does longer shelf life have on the quality and profitability of baked goods?

A longer shelf life translates to improved product quality and increased profitability. With Strayfield RF Drying Machines, the drying process helps remove excess moisture, reducing the risk of spoilage, mold growth, and staleness. This extends the shelf life of baked goods, enhancing their overall quality and market value.

What makes Strayfield's RF Drying Machines more energy-efficient compared to other options?

Strayfield’s RF Drying Machines boast the highest energy efficiency in the industry. We incorporate a filtered oscillator design and a double electrode balanced output, which minimises energy losses, optimises power distribution, and reduces RF emissions. This ensures maximum energy utilisation and compliance with industry standards.

Can you explain the significance of the filtered oscillator design and its compliance with standards?

The filtered oscillator design in Strayfield’s RF Drying Machines is crucial for meeting compliance standards, such as EN55011 and CE. This design reduces electromagnetic interference and ensures that the emitted RF energy is clean and well-controlled, adhering to regulatory requirements and maintaining a safe operating environment.

How do the automatically adjusting electrodes contribute to controlled power and arc suppression?

The automatically adjusting electrodes in Strayfield RF Drying Machines enable precise control of power delivery during the drying process. This ensures consistent and controlled heating, minimizing the occurrence of arcs. The result is improved drying performance, reduced downtime, and enhanced safety.

Why is the staggered electrode design important for uniform and gentle drying?

The staggered electrode design plays a vital role in achieving uniform and gentle drying. By utilizing this design, the power density is distributed more evenly across the product, reducing the risk of localized overheating. This ensures that the drying process is gentle and uniform, preserving the quality and integrity of the baked goods.

Are there any operational advantages of using RF Dryers in baking?

Integrating RF dryers can increase the throughput of conventional ovens and reduce the overall footprint required for drying equipment, thereby optimizing bakery floor space and reducing energy consumption.

What types of baked goods can benefit from RF Dryers?

A wide range of baked products, including crackers, crispbread, biscuits, and confectionery items like sponge cakes and wafers, can benefit from the uniform drying provided by RF technology.
