Refrigeration equipment is at the heart of any semi-prepared food production plant and food processing facility. In this article, we will look at where such systems are used, the problems that blast freezing solves, and the solutions employed on modern production lines. We will also focus specifically on equipment from Dalgakiran and its use in the production of frozen meals and semi-prepared foods.
Where refrigeration equipment is used for frozen semi-finished products
In the food industry, refrigeration units maintain the desired temperature conditions during the preparation of raw materials, the production of food products and subsequent storage.
Most often, such refrigeration equipment is installed at facilities producing semi-prepared and ready-made products for supermarkets, restaurants and delivery services. These may include dumplings, pizza, meat or vegetable mixes, as well as various ready meals.
Main areas of application:
Rapid food freezing lines.
Freezer chambers for storage.
Packaging and sorting areas.
Finished product warehouses.
Industrial refrigerators ensure safe storage conditions across all production areas within the industry.
‘In the production of frozen foods, it is not just the capacity of the equipment that matters. Far more important is the stability of the temperature regime at all stages — from preparation to packaging and transport. It is precisely this that affects the quality and shelf life of the products,’ the experts point out, highlighting another interesting detail.
The main objectives of blast freezing
Flash freezing is used to rapidly cool products to very low temperatures in order to preserve the structure of the ingredients, their flavour and nutritional properties. This is vital for the production of ready meals and semi-prepared foods, which are subsequently transported and stored in a frozen state. In the modern food industry, this technology has become the standard.
The main objectives of flash freezing are:
rapid cooling of the product after preparation;
preserving the structure of the ingredients;
reducing the risk of bacterial growth;
extending the shelf life.
Once this stage is complete, the products can be stored in freezers for long periods without any loss of quality.
Dalgakiran chillers for freezing tunnels
Chillers — water or glycol cooling systems — are often used to operate freezing tunnels. They operate as part of large production lines where a stable temperature is required.
Chillers are used in various parts of the production line.
Line component
Purpose
Freezing tunnel
Rapid cooling of products
Freezing chambers
Long-term storage
Heat exchange systems
Heat transfer between circuits
This enables the plant to maintain a stable temperature regime even under heavy loads on the production lines.
Cooling towers and heat exchangers in semi-finished product lines
Heat exchangers and cooling towers are used in large cooling systems. They help to remove heat from the refrigeration unit and stabilise the operation of the entire complex.
In the production of semi-finished products, these components are used for:
cooling process water;
maintaining equipment temperature;
reducing the load on the refrigeration unit or chiller.
This enhances the capabilities of the entire production system.
Compact air conditioners and heat pumps for packaging areas
Packaging areas also require precise temperature control. If the air in the workshop is too warm, this can affect the quality of frozen products. Compact air conditioners or heat pumps are used for such areas. They also help maintain a stable climate in rooms where finished products are handled.
Special attention should be paid to situations where the packaging area is adjacent to a freezer room. In such cases, the temperature difference between the zones can cause condensation to form on surfaces and packaging, which impairs the product’s appearance and shortens its shelf life. This is precisely why refrigeration equipment for such premises is selected comprehensively, taking into account heat flows between zones, air humidity and the intensity of staff movement.
Thermostats for stable freezing
Various sensors and thermostats are used to ensure a stable freezing process. They monitor the temperature in the chambers and transmit data to the control systems.
Such devices are used for:
monitoring the temperature in tunnels;
monitoring storage facilities;
managing the operation of refrigeration units.
As a result, the production process remains predictable, and the products meet standards and are safe for consumption.
