Aquaculture

Dosing units, silos, and various conveyors.

Gentle feed handling is crucial in the production of feed handling equipment for aquaculture, where Helland Silosystem has been producing and supplying silos and conveyors to national and international customers since the 1980s.

In recent years, the silo manufacturer has also developed feed dispensers for the aquaculture industry and delivers to facilities both in Norway and abroad.

The equipment is customized for each individual customer, and a dedicated test facility at the factory in Gjesdal municipality in Rogaland ensures that everything produced meets each customer’s quality requirements and needs.

Silos for Aquaculture.

Helland Silosystem produces outdoor silos, big bag silos, indoor silos, modular silos, and low-profile silos, and customizes these to each individual customer’s needs. The silos are also adapted to various filling methods, whether it’s from bulk trucks, bulk boats, blowing systems, or big bags.

Regardless of the solution, the following always remain the focus: even filling and emptying of the silo, gentle feed handling, and quality.

Dosing units for feed

Our dosing units are designed with an emphasis on gentleness, functionality, and precise and even dispensing, so that the fish have the best possible conditions for good growth. A circular container with a round, smooth cone ensures good emptying.

The dosing units can be adapted to different control systems and can also be integrated into existing facilities and control systems.

Dosing unit 400

This is a small and compact dosing unit adapted for small feed. The dispensing has gram precision and is used for initial feeding and in tanks requiring smaller amounts of feed.

The dosing unit can be mounted on a walkway, tank edge, or floor stand. A transparent container provides good visual control of the feed in the tank.

Characteristics:

  • Volume: The container is available from 50 liters up to 100 liters
  • Feed size: 0.3mm to 3mm
  • Application: Initial feeding and fry.

Dosing unit 600

This dosing unit is a versatile dispenser that covers most needs. It is available with several container sizes and can thus be adapted to different tank and pellet sizes. The dispenser is gentle on the feed and provides an even dispensing so that the volume in the tank is utilized as efficiently as possible. The dispensing tube is adapted to the pellet size, and the dispensing holes are tailored to the tank’s design.

The dispenser can be mounted on a walkway, tank edge, or floor stand. The cone is round and without internal bolts, which ensures good emptying. A transparent container provides good visual control of the feed amount.

Characteristics:

  • Volume: The container is available from 100 liters up to 300 liters
  • Feed size: 0.5mm to 9mm
  • Application: Growth, pre-smolt, smolt, and post-smolt

Dosing unit 950

This dosing unit is designed for larger aquaculture facilities where feed is often stored by the tank. The unit is adapted for larger feed types and equipped with an inspection glass, making it easy to see the level in the container.

Characteristics:

  • 45-degree cone for good emptying
  • The container is available from 500 liters up to 1000 liters
  • Feed size: 6mm-12mm
  • Application: Post-smolt and grow-out

Feed Weight

In order to control the amount of feed stored, and to ensure the correct amount is fed to the fish, it’s important to have good weighing solutions.

For this, we customize the solution and weighing cells according to the feed amount to be processed.

We provide several solutions for this:

  • Weighing cell on silo
  • Feed weight that weighs up batches
  • Weighing cells on the feed dispenser for precise dosing.

Portable Blower Unit

The blowing unit is used to empty big bags and transport feed to a silo. The equipment is designed for gentle handling of the feed and has a capacity of between 10-12 tons per hour, making it practical for logistics involving large quantities of feed. It is supplied to fit the 102mm Perrot system or the 160mm system.

Supplied with:

  • 1500 or 2300L bag funnel, knife cross, and grid
  • Blowing unit with 15 or 18.5 kW power. Custom-developed inlet and outlet for the sluice
  • Can be moved with a forklift
  • Supplied with electrical control and connection for extension cable
  • Feed size: 1mm-9mm
