Industrial freezer for storing raspberries

Raspberries are one of the most popular and tender berries. It is used in the food industry for the production of juices, jams, desserts and other products. However, due to its structure, raspberries have a short shelf life in fresh form. For long-term preservation and year-round access to this berry, manufacturers use industrial freezers that allow preserving its taste, nutritional and visual qualities.

Why is it important to freeze raspberries?

Raspberries have a very thin skin, flesh with a high water content and vulnerability to temperature changes, which makes it particularly susceptible to spoilage. Even under refrigeration conditions, it is not stored for more than a few days without loss of quality. That's why freezing is an ideal method for extending its shelf life. Quick freezing allows:

Preserve the taste, aroma and texture of raspberries;

Support its nutritional properties, including vitamins and antioxidants;

Ensure availability throughout the year, regardless of the season.

These characteristics make raspberries popular among producers who offer frozen berries that can be used in various recipes and industrial processes.

Basic requirements for industrial freezers for raspberry storage

To preserve raspberries on an industrial scale, freezers must meet a number of requirements. In particular, this applies to the temperature regime, the freezing rate and the conditions for maintaining stability.

Storage temperature. Long-term storage of raspberries requires a temperature of -18°C to -25°C. This temperature regime ensures the absence of microbiological spoilage and allows the berry to be stored for up to 12 months, which is the optimal period for maintaining quality.

Fast freezing. Shock freezing, carried out at temperatures below -35°C, ensures the rapid formation of small ice crystals inside the berry. This is especially important for raspberries, as a large ice crystal can damage the cellular structure, resulting in a loss of texture. Shock freezing minimizes such losses, preserving the softness and appearance of raspberries.

Humidity control. The optimal level of humidity helps to prevent dehydration of the berries, which is important for maintaining the texture and weight of the product. Industrial freezers must have a humidity control system so that the berries remain juicy after defrosting.

Uniform circulation of cold air. The uniform circulation system ensures the same temperature throughout the entire volume of the chamber. This helps to avoid the formation of cold and warm zones, which allows you to freeze large batches of raspberries with the same quality.

Energy efficiency. Freezers must be energy efficient, because large volumes of frozen products require significant resources. Equipment with a high energy efficiency class allows you to reduce the company's electricity costs.
