The vacuum suction system comprises the following elements:

  • Vacuum tank, where the negative pressure required for the transfer is generated.
  • Power unit, with the vacuum pump, motor and valves for the operation of all the elements of the system.
  • Control panel and control unit to adapt the pump performance  to the working conditions at all times.
  • Suction and ejection manifolds for product distribution.



Function of the tank

Watertight stainless steel tank, designed for transferring fish waste by means of vacuum.

A vacuum pump generates a negative pressure or vacuum inside the tank to suck the viscera from a heading machine.

Once the tank is full of viscera, it is discharged by gravity through the opening of a gate.

The capacity and shape of the tank are designed according to the application.

In order to obtain the necessary airtightness inside the tank, the tank has inlet and outlet ports of nominal diameter according to the size of the product to be transferred, equipped with pneumatic valves governed by a PLC control system, which opens or closes them depending on a given pressure.
