Freezing and Cooling Tunnel

SRT (Single Retention Time)

Today SRT freezing and cooling tunnels from Hans Jensen Engineering are installed world-wide. The first tunnel was installed in 1972 at a Swedish customer, and it is still running daily.

The individual tunnel is customized according to required capacity, dimensions and integration of the total production cycle from filling machine to packing machine. HJE delivers a turn-key solution inclusive evaporators and insulating panels, doors and Stainless Steel floor.

In order to ensure optimum product flow it is recommended that HJE also supply all conveyors from filling machine to tunnel and from tunnel to packing room/storage facilities. The control of these conveyors and evaporators will be an integrated part of the advanced program of the tunnel.

All tunnels are assembled at our own workshop, where they will be tested, dismounted and forwarded to the customer. Due to this procedure, installation and starting up can be made within relatively short time, thus minimising the duration of production stops.

Our tunnels are continuously developed as a result of our corporation with customers and their requirements to efficiency, reliability and safety of food as well as flexibility. Frequently, from our present customers we hear the following statements of our tunnels and the ongoing corporation with HJE:

  • High reliability
  • High flexibility
  • More output capacity than expected
  • Technically reliable solutions
  • Impressive finish
  • Effective and quick support from HJE.

As standard, all new tunnels are prepared for internet connection. Consequently, HJE can within a short time assist and support the customer on-line – saving both time and money for the customer.

Configurations

SRT´s flexibility is characterized by the fact that in each case the tunnel is customized according to the needs of the customer and not the other way round.

Due to this flexibility of construction of the individual tunnel, the customer gains optimum utilization of available space, which is very difficult with other types of tunnels, where the customer has to adjust space to the tunnel.

Apart from flexibility of size, we also have various choices as to input and output of products.

Advantages of SRT:

  • Can be used as a buffer storage over night or over weekends
  • Capable of handling different sizes of products at the same time
  • High reliability and long lifetime
  • Easy to clean and maintain
  • Dehumidifier System (Optional)
