PROCESSING OF COLD WATER SHRIMP

 

Highly technical experience gathered from equipping more than 200 factory trawlers with Carsoe processing plants is at the disposal of ship owners contemplating new projects. Beginning with a thorough evaluation of the production needs of a trawler, Carsoe ensures that the processing capacity and finished product are strictly in accordance with the individual requirements of each trawler.

CONVEYOR SYSTEM

Robust and sturdy design that withstands the rough environment onboard. The conveyor belts are of plastic modules, rubber or stainless steel and the belts are equipped with different kinds of flights depending on product and incline.

BY-CATCH SEPARATOR

An increase in capacity, staff reduction and a long service life are tangible benefits to be achieved with Carsoe’s flexible by-catch separator.

Automatic separation of small fish is crucial for an efficient and cost-effective shrimp production onboard. Carsoe’s separator ensures a higher capacity than manual separation which besides being far less efficient also demands more staff on the line. Furthermore, with this unit a much cleaner product is achieved and further processing on shore made considerably easier.

It is the difference in surface texture on shrimp and fish that enables the separation process. The fish is transported upwards whereas the shrimp slides downwards. This also makes the separator suitable for separation of soft shelled shrimp in seasons where those swarm the waters.

The separator is equipped with an electrical cylinder that makes the adjustment of the angle of the conveyors less time consuming. A unique tilting system makes for an even spread of product on the conveyors in case of heeling and thus a more efficient separation process. The drive drums on the conveyors are made from rubber which ensures a substantially longer service life.

Focus in the design of the separator has also been for easy maintenance and easy cleaning. The open construction makes for optimized production hygiene through quick access to critical areas

SHRIMP GRADER

The Carsoe grader type CS 1014 is designed for grading shrimp in different sizes, and it is applicable for plants both on board and on shore. The grader offers a gentle and accurate thickness grading and is available for both cold water and warm water shrimp.

A feeding chute distributes the shrimp evenly on two oscillating screens with individually adjustable rails and the shrimp are led out at a suitable gap. Grades from 4 up to 7 sizes, leading the small shrimp out first while the larger ones continue till the edge of the screen. A carrier chain ensures a continuous

grading process without any product accumulation. The grader is equipped with either electric or hydraulic motor on request. A quick adjustment system for easy change to other shrimp sizes is optional extra. Furthermore, equipment for collection and recirculation of processing water is optional extra.

The open stainless steel design facilitates daily cleaning. The grader is equipped with automatic lubricant injectors and requires but a minimum of maintenance.

BELT GRADING MACHINE

High capacity, no vibrations, low water consimption, flexible quick size adjustment system. Applicable for shimp, herring, mackerel, sprat, trout and carp ranging from approx. 100g up to 2 kilos. It provides a very gentle fish grading up to 5 sizes.
