Industrial microwave defrosting and tempering of frozen fruits
Industrial microwave defrosting and tempering of frozen fruits was the solution chosen by a leading Czech food manufacturer producing different kinds of products, including fruit ice-cream. Currently the leading food distributor in the country for hotels and restaurants, their worldwide turnover is €9 billion.
Before adopting this solution, the customer used to place the fruit in a defrosting room for 24 to 48 hours, depending on the product. This method was extremely long and created many quality issues caused by the huge difference in temperature between the core and the surface of the batch after defrosting. Moreover this method caused major product drip-losses.
Frozen fruit processing challenges
The company was looking for a way to improve their fruit tempering process by reducing the defrosting time and eliminating drip-losses. The solution also needed to retain the taste and appearance of the product (mainly raspberries) and achieving a uniform temperature throughout the large quantities of fruit. Cost reduction was also a key requirement.
Our industrial microwave tempering solution for frozen fruits
To solve this customer’s problem, SAIREM provided a NutriTemp batch microwave tempering oven. The system includes 2 sliding tables, allowing them to load 10-15 kg of raspberries per batch. This industrial microwave defrosting and tempering of frozen fruits solution prevents drip-losses, preserves the quality of the product. Defrosting time is also considerably shortened. The process now takes only 6 minutes, compared to several hours previously.
Key benefits of industrial microwave fruit tempering
- Speed: thanks to very quick tempering from -18°C to -4°C / -2°C.
- Savings: the weight of the product before and after tempering is exactly the same because drip-losses are prevented.
- Quality: the quality of the fruit is fully preserved thanks to perfect temperature homogeneity after the tempering process.
The machine was installed in 2015 and has been running every day since. Moreover, 3 other machines have been ordered by the company to temper additional products such as meat, fish and vegetables.
NUTRITEMP RANGE
Our microwave and radio frequency tempering and defrosting solutions are designed for industrial food processing applications requiring fast, controlled, and uniform tempering and thawing. They support both packaged and unpackaged products, ensuring precise temperature control prior to further processing.
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.
Calculate your payback
How much is drip loss really costing 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.
