Refrigeration equipment for fish processing and seafood

The cold chain in the fish industry requires special attention. If there is a breach at even one stage, the batch of seafood or fish is already unfit for consumption. That is precisely why companies that take quality seriously build their production processes exclusively around reliable refrigeration equipment. In this article, we will look at the systems used in fish processing and what Dalgakiran offers for this sector.

The importance of refrigeration equipment for fish processing and seafood

Fish and seafood are the food products most sensitive to temperature. Without high-quality freezing and refrigeration equipment, it is impossible to meet food safety requirements and compete in the market.

‘Most cases of food poisoning from fish and seafood are not linked to the quality of the raw materials, but to a break in the cold chain at one of the stages – often the simplest one.’

The main objectives of fish cooling and ice production

Cooling fresh fish immediately after receiving the raw materials is the first step in the production chain. Here are the main tasks performed by refrigeration equipment in production.

1. Rapidly lowering the temperature after raw materials are received.
2. Maintaining a stable environment in storage chambers.
3. Production of food-grade ice for transport.
4. Cooling of glazing lines.
5. Freezing finished products in freezing tunnels.

Carefully selected cooling systems enable the required conditions to be maintained in each section.

Dalgakiran chillers for glazing lines

An even layer of ice protects seafood and frozen fish from dehydration during storage. Industrial chillers are used to cool the water in glazing lines. Dalgakiran offers several current ranges: Pakcold — with a cooling capacity ranging from 6.4 to 150 kW, RWE — water-cooled chillers for indoor installation with capacities ranging from 6 to 87 kW, and EBHV-FC — from 124.1 to 962.0 kW for large-scale production facilities. All models are designed for round-the-clock operation in high-humidity environments.

Cooling towers and heat exchangers in fish processing facilities

In large-scale production facilities, cooling towers and plate heat exchangers remove heat from process operations and operate in conjunction with chillers. Here are some differences in their application:

Compact air conditioners and heat pumps for production halls

Excessive humidity and heat in the workshop compromise the safety of the production process. Compact industrial air conditioners solve this problem and can be easily integrated into existing ventilation systems.

They offer several practical benefits.

1. A stable air temperature in the workshop throughout the year.
2. Reduced humidity, which prevents the growth of bacteria.
3. The ability to operate in heat pump mode in winter.

‘A workshop with an unstable microclimate places an additional strain on the entire refrigeration system: equipment wears out faster, costs rise, and the end result is poorer,’ experts point out. 

Thermostats for keeping seafood fresh

For delicacy seafood — such as oysters, crabs and mussels — it is not just the cold itself that matters, but also precision. Modern thermostats maintain the temperature within ±0.5 °C. Refrigerators and storage chambers with this level of control enhance food safety and reduce customer complaints. When you choose Dalgakiran, you can be confident there will be no inaccuracies.
