Food Ingredient Defrosting and Tempering
Defrosting & Thawing Process
Tempering and defrosting are key steps in processing frozen products.
Uniform temperature ensures consistent operations, preserves product quality, and maintains food safety, while traditional methods like defrosting rooms or tumblers may not always guarantee full uniformity, especially for large or dense products.

Calculate your payback
How much is drip loss really costing you?
How much could microwave defrosting save you ?
Every thawing cycle comes with hidden losses. Depending on your product and process, drip loss can reach up to 8% of total weight, directly impacting your margins before production even begins.
With just a few inputs, you can estimate your actual financial losses and identify how much you could recover with a more efficient defrosting solution.

Available in batch, compact, and modular designs, our space-saving tempering and defrosting equipment adapts to different production volumes, site constraints, and product types. With remote control connectivity for monitoring and process optimization, our systems deliver consistent product quality, reduced lead time, and stable, efficient production flow across a wide range of operating conditions.
Here’s a questions-and-answers section about our microwave and radio frequency tempering solutions.
Tempering and defrosting involve heating or thawing products to an optimal temperature before processing, cooking, or further handling. Our solutions use microwave and radio frequency technology to quickly and uniformy temper or defrost products, reducing time and product losses compared to traditional methods.
Our systems are designed to handle a wide variety of food products, including butter, meat, poultry, seafood, fruits, vegetables, and other frozen foods. Our range of solutions can adapt to the tempering or defrosting needs of your products, and in some cases, products such as sunflower butter can even be melted.
Compared to conventional methods such as thawing chambers or defrosting tumblers, microwave and radio frequency tempering and defrosting dramatically reduce processing time. While traditional defrosting methods often require several hours, microwave and RF systems can temper or defrost products in minutes, significantly increasing production throughput.
The fast and controlled heating ensures a more uniform temperature distribution, limiting quality degradation and reducing product losses caused by uneven thawing or overheating. This results in improved yield, consistent product quality, and a more efficient and reliable production process.
Yes, microwave and radio frequency tempering can be effectively combined with thawing chambers and defrosting tumblers as part of a hybrid defrosting process. When used as a pre-treatment, these technologies help reduce the overall defrosting lead time while maintaining controlled and uniform temperatures.
Depending on the product type, size, and initial temperature, this combined approach can reduce total defrosting lead time to around 6 hours, compared to more than 10 hours when using conventional defrosting methods alone. This allows for improved production flexibility and throughput, while preserving product quality.
