Two tunnels for fish and vegetables: tempering in under 10 minutes
A Finnish producer of frozen vegetables, fish and ready meals thawed its raw materials for several days in a thawing room. Two NutriTemp continuous microwave tunnels now temper them in under 10 minutes and have cut drip loss by 3 %.

Customer
A Finnish producer with more than 400 employees. It supplies frozen vegetables, fish ingredients and frozen ready meals, and is the leading brand of vegetable-based ready meals in its country.
Challenge
The plant had no fast thawing solution and used a thawing room where ingredients took several days to thaw. The customer needed to temper 10–20 kg blocks of vegetables and fish from −18 °C to −4/−2 °C faster and more evenly, without hot spots or drip loss. Because of allergens, fish and vegetables had to stay separate.
Solution
Sairem supplied two continuous lines:
- NutriTemp Compact for fish,
- NutriTemp Flex, a larger tunnel, for vegetables.
Each product has its own line, so there is no risk of allergen cross-contamination.
Results
- Under 10 minutes of tempering instead of several days.
- 3 % less drip loss, which adds up to significant money at large volumes.
- Better quality thanks to fast tempering and the same temperature throughout the block.
- Less waste: exactly the amount needed for the day is thawed.
- Safety: fast, even tempering prevents microbial growth on the block surface.
