Jackstone Inline Tunnels
The Inline can be used as a Freezer, Chiller or Conveyor, ideal for seafood, fruits, vegetables, meat, bread & pastries.
The Jackstone Inline Freezer is our simplest, straight through design, with custom made belt widths & lengths depending on your product & line requirements. The belts are at a convenient working height for your workforce.
These machines are economical, hygienic and low maintenance. Site installation is straightforward, with little disruption to your factory.
Jackstone are pioneers in the Dual Airflow System, which can dramatically increase freezing times.
By the use of a dual air system, with air mixing, velocities over the product can be increased to between 10 to 25m/s.
When freezing thin products, such as beef burgers, freezing times using air at -45 deg C, are comparable to those using liquid Nitrogen.
High velocities are achieved by the use of two sets of fans, shown the diagram, one set using a low face velocity across the refrigerated coil, resulting in reduced fan power, the other set maintaining an even and higher air velocity over the products. The two air streams mix providing the refrigeration effect on the product.
