Grading live fish is a fairly hard and complicated process. The system normally
consists of three to four grades where the operator can dynamically adjust the grades
on the fly. The system falls under the category of a multi input, multi output system
(MIMO). The system is operated by two to four persons at a time and it is sensitive to
any changes, a small change to the input can cause a dramatic change in the output
and it’s not uncommon that 100 of
thousands
of fish are graded in one session
and
t
he
size range varies from few grams
to a few
hundred grams.
All these factors contribute in making the system fairly complicated and hard to tune
and more often than not results in
an unsatisfactory
output. It requires a lot of
knowledge about the system and a lot of practice to obtain a reasonable result.
SmartFlow connects all the devices used for grading fish in a hatchery to allow for an
automatic grading. SmartFlow is a control system that optimizes the grading process
by controlling the entire process. With SmartFlow you only need one person to
operate the whole system with fundamental knowledge of grading. You can control all
aspects of the grading from
within SmartFlow. Enter in your desired output and the
system takes care of the rest.
Set up
When setting up SmartFlow the following
system configuration is
required
:
●
A VAKI counter (Micro/Macro/EXEL).
●
A VAKI Smart
G
rader
●
A VAKI pump
●
A VAKI density controller
●
SmartFlow configured and running on
the
counter.

VAKI Smart Grader
The Smart Grader delivers accurate fish grading while minimizing the impact on your
fish as they pass through the outlets. The dewatering unit distributes the fish evenly
over the width of the grader, so all 10 tracks are used effectively.
Further the inclination of the main sorting unit can be adjusted from 5-14° with an
electric actuator. The opening of the grader is controlled with electric linear actuators
that can be manually operated from a control panel on the grader or automatically
from the VAKI Counter which counts, size measures and calculates the split between
the grades. The opening for each grade is displayed on a digital display. The grader is
built in high grade stainless steel 316L and selected plastic materials that are corrosion
and water resistant.
The rollers are machined with high precision laser welding tools and balanced out with
specialized equipment. It delivers an accurate grading of the fish. The outlets are
designed to minimize the impact on the fish and can be mounted to deliver the fish on
either side of the grader. These outlets can easily be removed for cleaning. The
rotation speed of the rollers can be adjusted with a frequency controller.
The grader functions by sliding the fish between two rolls, where the distance
between them gradually widens. Where two pairs of rollers rotate away from each
other to make sure that the fish doesn’t get squeezed between the rollers, but instead
lifted up and pushed forward so they fall through in the correct place. The expansion
of the slits on both ends can be adjusted. When operating the grader you have to
keep in mind that the grades are all related to one another. One single grader gap

2.2.2 Counting session controls
A.
Capacity indicator.
The bar will be
green at 0-70% of maximum counting
capacity, yellow at 70-100% and red at a
load over 100%. The risk count accuracy
decreases when the load is over 100%.
B.
Channel
. The name can be changed by
pressing on the channel name, the on-
screen keyboard will then appear.
C.
Total number of fish
counted. Double-
clicking the field will clear the number to
zero. The cleared number will be stored
in the report.
D.
Weight adjustment buttons
to select
the average size of the fish to be
counted. Choose the weight closest to
the expected average. Selected weight is
displayed directly above the buttons.
E.
Counting/Not Counting
indicates the
state of the counter. If this area is red,
"Not counting" is displayed and there is
an error message regarding visibility and
/ or calibration. See chapter Calibration
and Visibility for more details.

2.2.3 Tabs
Different information about the counter can be accessed by the tabs in the main screen. Each view
holds different information about the counter, and all of them assist in getting the best results out of
the counter.

2.2.3.1 Throughput
Graph will show the number of fish per minute passing
through the counter. The red line indicates the
maximum capacity and the blue line shows the actual
number of counted fish per minute.
2.2.3.2 Video
Real-time display of the camera's video. This can be
used to see fish passing through the counter, any
impurities or bubbles in the water, or residue on the
glass or mirrors.
2.2.3.3 Spread
A graphical representation of where fish are passing
through over the width of the counting channel.
