Overview

VAKI has developed an automatic Feeding System in cooperation with fish farmers and delivered their solutions to many farms in Iceland and Scotland. The system is installed in containers and simple to use, and is specially designed for smaller farms. The system utilizes one or more feed storage silos, which is useful when different sized feed is used.

The feeding system can be set up as refilling system for smaller feeding hoppers. Both as single revolver system and multi slave system.

Features

Components

Funnel

Is used to guide the feed dropped from the silos into the airlock. On the top of the funnel is plastic cover to prevent the dust.

 

Air Lock

Allows feed to enter the compressed airflow without losing air pressure or scattering the feed.

 

Sensor

The sensor on the funnel stops the system if the funnel becomes blocked or is full of feed.

 

Blower

Sends compressed air through the main pipe to transfers feed from the airlock to selected cage via the revolver.

The blowers are selected for the requirement of each system.

 

Rotator Selector Valve

The rotators  controlled with encoder and PLC which Selects correct pipe.

 

Pipes

Pipes from cage are connected to Rotator.

 

Optional Components

  • Cooler
  • Feed storage silo
  • Augers from silos
  • Pipes to cages

How It Works

Feeding operation is based on feed from the storage silo the silo empties into a feed dosing auger. The auger moves this feed into a funnel which make sure that the feed goes to airlock and then into the main transport pipe. Air blower blows air into the distribution valve where it is directed into the individual feed pipes and transferred to specific cages.

The operation of the system is controlled by Programmable Logic Controller (PLC). Programmed computer software is used to interface and program the feeding system. The software controls feeding operation such as feed rates, meal times, feed types, etc. The operator, can monitor, interface, reprogram or override the automatic operation of the system.

VAKI Feeding System are used today for farming salmon and trout.

Technology

Advanced Software

The operation of the system is controlled by a PLC. Computer software is used to interface and program the feeding system. The system software controls feeding operation such as feed rates, meal times, feed types, etc. The operator can monitor, interface, reprogram or override the automatic operation of the system.


Maximum Fish Growth

The VAKI Feeding System controls the quality of the feeding and thereby helps attain maximum fish growth and health. In other words the control sees to it that the fish utilizes a maximum of the nutrients in the feed for growth, while a minimum of nutrients are lost to the water. A more efficient uptake of nutrients in the fish doesn’t only benefit the environment, but it also improves farm economy.
