Soaking screw conveyor for salmon – 25440

2 pcs. soaking screw conveyor for salmon processing designed and manufactured by BEMA.

Key points of the design of the soaking screw conveyor

1. The trough acts like a tank and are filled with water during the transport of salmon
2. The tank has 2 purposes:
   1. Thawing of frosen salmon or bleeding the salmon right after slaughtering
   2. Ensuring the salomon to have a specified retention time during the transport
3. The screw flights of the soaking screw conveyor are manufactured with screw flight with holes for water to pass through
4. The screw flights are manufactured like a meccano system. The screw flights are bended in a conventional bending machine. In this case there is no need for it to be smooth

Due to handling salmon which is a food ingredient the soaking screw conveyor is manufactured in accordane with EC-1935/2004 – “the food directive”

The screw conveyor for salmon is acting as a process machine.

Description of the process features

1. The soaking screw conveyor is transporting the salmon from an inlet point to another point in the manufacturing process
2. During the transport the salmon is bleeded

The only unknown is the retention time, which can be controlled by using a frequency inverter together with the electrical motor.

In BEMA we strongly recommend to be cautious when you design process screw conveyors:

• You should not implement more than one process component into the screw conveyor

In the actual case for the soaking screw conveyor, the process component is the retention time. If you add several processes into the screw conveyor you have a great risk to make a design error. In case one of the processes fail, you will not be able to adjust on it without affect on the other processes. This is very important to understand.

In BEMA we have engineers and technicians that can assist you during the design. With the right cooperation you will be able to get a workable solution in cooperation with BEMA.
