IQF batch freezers

Cryogenic batch equipment is ideal for food and metal treatment.

In the case of food, it is especially relevant for freezing and chilling food that require no linear or continuous procession along a line, e.g. in small companies or product lines, testing applications or institutions with inhouse cafeterias. In terms of metal treatment, cryogenic batch freezing is often used for sub-zero treatment in the auto, aviation, aerospace, and machine tooling industries.

Our cryogenic batch freezers and batch chillers are based on the same freezing process, where liquid is sprayed, and vapor is circulated by fans to ensure rapid freezing and chilling. Controlled over-pressure inside the equipment pushes the excessed gas out – this is also known as 'passive exhaust'. This makes the solution easy to install, as it doesn’t need an external exhaust blower or a gas purge.

The batch chiller and freezer have adjustable nozzles to handle changing requirements or items requiring slower freezing or chill time to prevent surface fractures.

Our range of batch freezers and batch chillers cover a freezer that comes in a single and double batch version and a cryogenic treatment chamber.

Batch freezer variants

Flexible batch freezing and chilling

Our batch freezer is suitable for deep freezing or very fast crust freezing and batch chilling for handling and packaging of delicate and soft food, such as bakery products, red meat, fish, and poultry.

A batch chiller or freezer is ideal for small to medium-sized businesses as they are designed to handle varying volumes of frozen food. A batch freezer has a low footprint, is easy to clean, and requires a relatively low capital investment. On top of that, it also ensures high and uniform food quality and improved yield.

Depending on your needs, the batch freezer machine is available in two versions. A single batch freezer and a double batch freezer with the capacity of two regular freezers.

Freezing, cooling, and heating for your industry

Batch freezing of pharma

Batch freezing is relevant for many industries where food safety and food quality are of the essence. That is why we offer customized IQF freezing for all types of industries such as baked goods, seafood, meat, poultry, and dairy products. It is also relevant in the nonfood industries, such as pharma and metal. At DSI Dantech, we offer the global food industry the possibility of one supplier of all thermal treatment solutions.


Cryogenic IQF for extremely fast freezing

Batch freezing is part of our cryogenic product range - the fastest IQF freezing method on the market. In cryofreezing, the items are sprayed or immersed directly in liquid nitrogen or carbon dioxide and frozen almost instantly. The method prevents the formation of macro crystals – which is preferable, as large ice crystals rupture the food’s cell membranes and cause fluid loss. The lack of macro crystals results in the highest product quality of frozen and chilled food that sustains its natural nutritional value, taste, and shape.
