AAT-FREEZING – Systems

We offer fully automated shock freezing systems, cooling systems, short-term storage systems and tempering systems for food in boxes or cartons.

AAT-FREEZING systems are among the most advanced freezing systems on the market. These systems are automatically loaded with the products through an air lock. After shock freezing, the finished products are automatically transported out. The Small BoxFreezer has a throughput of 100 kg to 2 tonnes per hour. As a result of specific adjustments, this is also compatible with the industry standard 4.0.

Advantages of AAT-FREEZING Small BoxFreezer:

The system can be easily extended or relocated due its modular structure.
Low assembly costs on site – the system is delivered in finished modules.
The Small BoxFreezer comes with an insulated foundation system – only a normal hall foundation is needed on site.
The Small BoxFreezer is available with a matching refrigeration system. The customer only needs the electrical power supply for the system.
Little to no ice formation in the Small BoxFreezer due to dehumidifying at the air locks.
Due to the Airflow Shelf principle, the products in the Small BoxFreezer are ideally circulated with air.
The Small BoxFreezer can be used for a wide range of products – cartons, crates, ice cream containers, dairy products, convenience food and many other types of product packaging.
An ingenious loading and unloading system, which works without pushing out the products, does not cause damages to the cartons, boxes or other product packaging. As a result, there is no dust, wear or dirt due to damage to the products.

AAT-FREEZING – Optimal Refrigeration Quality for Your Products

The Small BoxFreezer is designed to ensure gentle handling of the packaging at the same time as maximum freezing performance.

IDEAL FOR PRODUCTS IN SMALL PACKAGING

The Small BoxFreezer is a cost effective, automated refrigeration or freezing system for products in small packaging or in small volume production such as cartons, crates, ice cream containers, dairy products, convenience food etc. The system is ideal for products with different freezing times.

Thoroughly designed down to the last detail

In contrast to comparable freezing plants, such as spiral freezers or cold rooms, products with different freezing times can be cooled with the Small BoxFreezer. This is just one of the many innovations that our Small BoxFreezer has to offer.

AAT-Freezing Small BoxFreezer Description

Input and output station:
The input station forms the interface to the other production areas, such as slaughter, cutting or packaging lines. As a seasoned expert in conveyor systems and special machine construction, AAT-FREEZING also offers a broad product portfolio in all of these areas.
Air locks:
It is possible to install a combined loading and unloading air lock or two separate locks for loading and unloading the system. To avoid ice formation, we use a MUNTERS air dehumidifier in our Small BoxFreezer.
Loading and unloading conveyor:
The loading and unloading conveyor ensures trouble free loading of the product carriers (airflow shelves). The products are gently placed on the product carrier by the conveyor system.
Lifting station:
The lifting station moves the products to the prescribed level and ensures optimal filling of the Small BoxFreezer. Product sorting according to freezing times is possible as well.
Insulation:
The Small BoxFreezer is completely encased in insulation to ensure efficient freezing and not wasting any unnecessary energy.
Innovative product carriers (Airflow Shelves):
The Airflow Shelves are designed to allow the airflow to pass through, above and below the products. As a result, they are cooled faster and more efficiently.
Refrigeration system:
The system is available with an efficient refrigeration system, which has been designed specifically for the plant. The Small BoxFreezer can also be connected to an existing refrigeration system.
Control cabinets:
The system is equipped with high quality electrical components, such as Siemens, SEW, SICK and Pepperl + Fuchs.
Air coolers:
The air coolers are mounted laterally relative to the direction of flow. This enables an even cooling along the entire system. In addition, this optimizes the air flow towards the product.

MODULAR INGENIOUS

AAT-FREEZING Small BoxFreezer horizontal extension

AAT-FREEZING Small BoxFreezer vertical extension

Modular extendable

In order to be able to assemble the entire system at the customer's site with a minimum assembly and commissioning time, the system is already assembled in advance in Austria, operationally tested and then dismantled into appropriate transportable modules (container size). Due to its modular design, the Small BoxFreezer can grow with the customers´ needs without constantly having to invest in new, larger systems. Extension is possible both in the horizontal and vertical direction, thus allowing for adaptation to the spatial conditions on site.

Airflow Shelves

The cold air stream flows around the product in a circuit. As a result, the product is cooled quickly and efficiently.

The ingenious design of our Airflow Shelf directs the air ideally and in a controlled manner over the product. Your product is frozen faster and more gently. This saves you time and money. The arrangement of the cooling unit allows a continuous flow of cold air through the open Airflow shelf floors. As a result, the cold air reaches the products faster, which significantly reduces the freezing time. Since the air only has to be distributed across the width of the system, the total distance that the cold air has to cover is shorter than with other systems. Consequently, the temperature curve is optimized, ensuring uniform freezing of the products.

Cold airflow

Air flow speed of 4-6 m/s
Temperature down to -42°C

Munters dehumidifiers

To avoid ice formation in our systems, we use Munters dehumidifiers. This ensures that there is no ingress of moisture into the BoxFreezer from the surrounding areas (slaughter or production rooms, etc.) and the products. This process is adapted to match individual conditions and ensure optimal freezing of the products.
