Shock freezing is a modern method for long-term preservation of the freshness and beneficial properties of vegetables. It can be carried out in various ways, but the optimal solution in several aspects is the use of specialized containers capable of rapidly cooling the products to the required temperature. You can always order them from Global Container Service – we have equipment for freezing vegetables of various types and modifications, which we are ready to promptly deliver to the port of any country in the world.

Shock freezing of vegetables in a reefer container – features and relevance

Shock freezing of vegetables is a process of rapidly cooling them to very low temperatures (around -30 to -50 degrees Celsius). This method instantly halts all biochemical processes in the products, allowing them to retain their original structure, taste, and nutritional properties. Unlike traditional methods, the shock freezing technology does not lead to the formation of large ice crystals that can damage cells and reduce the quality of the product.

Advantages of using shock freezing

Rapid freezing of vegetables has many undeniable benefits, making it optimal for processing carrots, broccoli, spinach, peppers, green peas, and other products, ensuring:

• Complete preservation of nutrients and vitamins, which is impossible with regular freezing.
• Hassle-free storage of chilled products for several months.
• Reduction of risks associated with vegetable spoilage due to the absence of ice inside the cells.
• No changes in vegetable texture and full retention of their original taste.
• Rapid freezing with minimal costs, which is extremely important for modern production.

Frequently Asked Questions

Do vegetables need to be pre‑treated before blast freezing?

Yes. Before loading into the blast container to ensure uniform freezing and preserve product quality, vegetables must be sorted, cleaned of dirt, and, if necessary, washed, blanched, or dried according to the processing technology for the specific crop.

How many vegetables can be frozen in one cycle in a 40‑foot container?

A 40‑foot blast freezing container with a usable volume of 66.7 m³ can freeze between 1.5 and 5 tonnes of vegetables per cycle. However, the actual load depends on the stacking method, the vegetable variety, product size, and the capacity of the refrigeration unit.

Is the blast freezing container suitable for seasonal crop processing?

Yes. The blast freezing container is widely used during seasonal vegetable processing when large volumes of vegetables, berries, or fruits need to be frozen quickly close to the harvest site in order to best preserve quality and reduce product losses during long‑term storage.

Can an existing reefer container be upgraded for vegetable blast freezing?

Yes, it can. To do this, the standard refrigeration unit is replaced with a more powerful one, thermal insulation is modified if needed, and high‑capacity air coolers are installed inside.

What are the operating costs of a blast freezing container?

When operating a blast container, you need to account for electricity consumption, diagnostics and scheduled maintenance of the refrigeration unit, repair and replacement of the most wear‑prone container parts, and sanitary cleaning and washing of the chamber before loading and after unloading the product.
