BoxFreezer

AAT-FREEZING – Innovative, Flexible and Powerful

Our BoxFreezers are full of innovations. Their design is thought through in every detail: saving space and achieving excellent adaptability.

Transverse Air Stream

The freezing blowers are arranged on the side of the BoxFreezer, so that the airstream blows directly into the product stack. The freezing air reaches the product faster and shortens the freezing time. The total air path is shorter than in other systems, because the air only has to cross the width of the plant. That means that if the plant is 30 metres long and 6 metres wide, then the system only has to chill the 6 metres. The result is a better temperature curve and more uniform freezing of the products.

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

AAT-FREEZING

Advantages of an AAT BoxFreezer:

  • Simultaneous freezing of different product types with different freezing times
  • Improved, guaranteed freezing quality
  • Labour saving operation
  • Savings on energy costs due to optimised freezing times
  • Savings on energy costs due to the multi-zone design concept – where zones are not needed, they can be simply switched off
  • Compact design enables high loading volumes
  • Long operating times between defrosting operations
  • Automatic loading and unloading devices with clear display of movement configuration and freezing times
  • Flexible, configurable loading and unloading strategy enables fast adjustments to changing production conditions
  • Scheduled unloading procedures can be programmed by computer
  • Database option allows storage and archiving of production records and data by the plant control system or by computer (Ethernet)
  • High availability and fast fault analysis via remote maintenance module or the Internet

 

AAT-FREEZING – Optimal Refrigeration Quality for Your Products

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

AAT-FREEZING – Assures Your Product Quality

Meat products are very sensitive and must be handled accordingly. With our BoxFreezer, the products are frozen as quickly as possible so that they are optimally preserved. Overall, our advanced freezers contribute to improved product quality.
 

AAT-FREEZING – Designed in Detail

Up to three freezing zones are available for products that need different refrigeration processes. This is just one of the innovations in our BoxFreezers.

  1. Presorting:
    Here the incoming products are presorted.
     
  2. Air locks:
    Thanks to the flexible design, the loading and unloading airlocks can be positioned at any point in the refrigeration cycle. It is also possible to install two loading airlocks and two unloading airlocks. To avoid ice formation in our systems, we use Munters air dehumidifiers.
     
  3. Insulation:
    The BoxFreezer is completely enclosed in insulation to ensure efficient freezing without unnecessary waste of energy.
     
  4. Air coolers:
    The air coolers are mounted laterally relative to the direction of flow. This allows for even cooling along the entire system. In addition, this optimises the air flow to the product.
     
  5. Innovative product carriers (Airflow Shelves):
    The Airflow Shelves are designed to allow the air to flow through the sides, above, and below the product. This will cool the product faster and more efficiently.
     
  6. Palletizing station:
    Here, the products are sorted for shipping or storage in an refrigerated warehouse.
     
  7. Freezer zones:
    The system can be designed with multiple freezing zones and can therefore adapt flexibly to your needs.
     
  8. Lifting station:
    The lifting system moves the products to the programmed level and ensures optimal filling of the BoxFreezer.

  • Damaged package
  • EAN code unreadable

The BoxFreezer delivers an optimal freezing curve and gentle handling of the packaging. The rapid freezing means your product spends the shortest possible time in the BoxFreezer.

AAT-FREEZING – BoxFreezer Systems for All Your Needs

Don’t settle for poorly designed systems. We are sure to have the right solution for you.

  • BoxFreezer
    In many variants ‘out of the box’. We are also the place to come for special designs. Our experts will analyse your requirements exactly, so that you get a BoxFreezer that is perfectly configured for the way you need to use it. We put efficiency and cost savings top of the list. For you that means optimum utilization, product safety and quality.
     
  • Pre-Sorting and Output Station
    We supply the complete pre-sorting system including the conveyor technology and control mechanisms to make sure your product workflow is as good as it can be. The same applies to the output station. We can also supply the subsequent steps such as manual or robotic packaging or transport to a high-bay warehouse. We can supply any special variants of these processes you wish for.

 

 

Multitemp – the innovation

Our BoxFreezers have three freezer zones that can be programmed independently. For example, one zone can be used for shock freezing at -20 °C and another zone can be switched off to save energy costs. The multitemp option is an exclusive innovation of our company.

 

Airflow shelves

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

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 pallet 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 travel is shorter than with other systems. Consequently, the temperature curve is optimised, 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.

AAT-FREEZING – Optimal Refrigeration Quality for Your Products

Best Possible Freezing Quality

A key aspect of our BoxFreezer is the outstanding freezing quality. The BoxFreezer delivers an optimal freezing curve and gentle handling of the packaging. The rapid freezing means your product spends the shortest possible time in the BoxFreezer. The colour and surface of your products are less affected and their appearance remains more appealing.

Presorting

Conveyor system and product sorting. Identification using the EAN code or RFID chip to ensure that only the same products are loaded together.

Input station

Before the freezing process is started, the presorted products are loaded onto the pallets of the BoxFreezer via a friction-free loading and unloading conveyor.

Transport

into the  corresponding freezing zone. The product carriers (Airflow Shelves) are transported via the lifting system to the pre-programmed freezing zone. At the same time a pallet is unloaded from the freezing cycle and transported to the output station.

Palletizing station

The product groups called up by the customer are now transported from the BoxFreezer to the pallet station and then prepared for shipping or storage.

In my point of view the BoxFreezer of AAT-FREEZING combines the most important basic principles of such a system, namely: The opportunity to drive at the same time different freezing times, the product is not moved by the BoxFreezer, but it is protected in the pallets, energy-saving fans through a split airflow, low maintenance, due to less moving parts in the BoxFreezer. These principles were very well developed and implemented by AAT. Additionally, necessary conveyor systems such as sorting and palletizing areas can be delivered perfectly. For this reason a complete transport concept can be delivered by AAT. If the product packaging allows a good heat transfer the BoxFreezer guarantees optimum freezing times. Based on my experience I can therefore highly recommend the BoxFreezer of AAT-FREEZING.
