Gutting and filleting machines


Kroma A/S is a family-owned company that is deeply rooted in the Danish engineering industry. The company dates all the way back to 1915, so we have a long tradition of manufacturing machinery for the industry in both Denmark and abroad.

1975 marked the beginning of Kroma’s production of machinery for the fish processing industry. The primary product was the popular Ravnstrup trout portion gutting machine.

In the beginning, it was only equipment for the trout industry that was developed and manufactured. It was first in the middle of the 1980s that we developed our first mackerel gutting machine. This machine was sold exclusively to smokehouses in Denmark and abroad.
At the beginning of the 21st century, the company changed its name to Kroma A/S. The focus also shifted much more towards product development – with an added strategic approach.

More products were launched on the market throughout the 2000s, but they were all related to the primary fish processing industry.
As Ivan Kristensen took over the controlling interest in the company in 2013, Kroma A/S moved to its current premises at 22, Rævevej in Skive.
