Key principles of frozen food storage

Maintaining freshness, quality and preventing microbial proliferation are the most important objectives of the freezing process. When exposed to low temperatures, <strong>vegetables, fruit, fish, seafood, meat and bakery products</strong> can reach customers and consumers with the highest quality despite the passage of time since harvest. The storage of frozen food plays a very important role in this process, due to the maintenance of controlled conditions tailored to the type of product. As Greenyard Logistics Poland, we make sure that freezing has a positive impact on foodstuffs and ensures the safety of consumers. We apply several principles that we can tell you about.

The right storage temperature for frozen food

What does this mean? The freezer in each of our company’s logistics centres is equipped to provide temperatures down to -22°C, which is the optimum temperature for storing fruits, vegetables and other food products. Temperature fluctuations have a negative impact on product quality, which is why our control systems constantly monitor the conditions in the freezer warehouses.

Warehouse insulation and efficient refrigeration systems

Both elements have a direct impact on each other. Good thermal insulation combined with advanced cooling systems helps to reduce operating costs. The storage freezer or warehouses generate lower costs, which translates into increased product competitiveness. Controlled conditions also ensure stable storage.

Individual and bulk packaging

Fruits and vegetables must be stored in moisture-resistant packaging. Moisture penetration could damage the products. In addition, the storage of frozen food requires the protection of items in bulk and individual packaging, depending on the customer’s requirements. Separation helps to avoid the transfer of odours.

Labelling, co-packing and product identification

The logistics process for frozen fruits and vegetables requires precise product identification. At Greenyard Logistics Poland, we perform co-packing, labelling and additional services for storing, packing, securing and shipping frozen food. Thanks to these procedures, freezer storage is under strict control.

Highest level of hygiene and experienced staff

Controlled freezer conditions help to maintain safe and adequate hygiene for the storage of products. This does not change the fact that our refrigerated containers and freezer spaces are periodically disinfected. The team receives up-to-date food safety guidelines to maintain the highest safety standards.

Types of freezers and how to adapt their parameters to the product

Adequate storage space is required for the proper storage of food products. In our company, we primarily rely on storage freezers. These are large-area and tall freezer spaces in which products are stored in low, medium and high bay systems. This makes it much easier for staff to access the products, which results in better management of storage resources.

The freezer store is always kept in a closed structure. This makes it possible to control the temperature, humidity and prevent unauthorised access. By choosing multi-level storage, space is saved and access to goods is made easier.

All freezer areas can also be subdivided according to the height of the temperature inside. The most common types of freezers are:

blast-freezing – advanced freezer warehouses that cause foodstuffs to be suddenly frozen while preserving their appearance, quality and nutritional value,

deep-freezing – the temperature prevailing in Greenyard Logistics Poland warehouses is -22°C. These are ideal conditions for vegetables, fruits and other food products resistant to low temperatures,

semi-deep-freezing – higher temperature freezers (-12°C to -18°C), as opposed to deep-freezers, are designed for products that are less sensitive to long periods of cold storage. These can include, for example, certain types of bread, confectionery and some ready-to-eat products,

higher-temperature freezers – freezers with even higher temperatures (-5°C to -12°C) are used to store products that require moderate temperatures, such as certain types of meat, cold cuts, cheese and other products sensitive to excessively low temperatures.

Another type of freezers are refrigerated containers. They provide ideal conditions for the transport and shipping of deep-frozen and blast-frozen products. At Greenyard Logistics Poland, we use these types of transport freezers for distribution, national, international and sea transport.
