Technology to reduce fees and losses after seafood harvest

In order to preserve aquatic and marine products after exploitation and reduce post-harvest losses, Viet Duc Investment Consultant Joint Stock Company (Ho Chi Minh City) has successfully tested the installation of a permeable cooling system on fishing vessels. put into operation first on Japanese Nam ship, initially bring positive results.

The cold-absorbing technology researched and installed by Viet Duc Investment Consultant Joint Stock Company is a cold-generating system, including: a cold compressor with a capacity of 20 horsepower, which is directly hybridized from the main machine or the lamp Ship, through the intermediate system to the heat exchange pipe system installed around the body and the bottom of the vessel, creates a cold to maintain the ice does not melt. This system easily adjusts the temperature in the range of 0-4 degrees Celsius, is guaranteed for one year, life expectancy is about 3 years.

According to Mr. Nguyen Van Truong (Japanese shipbuilder), this is the third voyage since the use of a permeable cold system installed by Viet Duc Investment Consultant Joint Stock Company. In the past, the production of seafood after catching in the traditional way of preservation, the rate of fish lost about 10-15% of the output.

After installing this system, almost 100% of the fish are of good quality, fresh and fresh as they were caught, not being devalued when marketed. In addition, when applying the permeability cooling system, the fish preservation time is longer (about 1 month and 10 days), creating conditions for fishermen to extend the working time on the sea, increasing productivity and exploitation output. seafood and income after each trip.

Mr. Nguyen Minh Duc, Director of Viet Duc Investment Consultant Joint Stock Company, said that the advantage of this permeable cooling system is to keep the ice from melting during the process of fishing and seafood exploitation, helping preserved seafood will be better, fish will not break the intestine, the ink will not be red and peeling, lose weight, not lose the cost of products. Simple installation system, does not occupy much ship space and does not need to change any structure on the ship.

The application of permeable cooling system also saves ice and fuel. Mr. Truong, said: when not installing the permeable cold system, each ship consumes 2,500 ice plants to preserve seafood, after installing this system, the ship only consumes 1,200-1,300 ice plants. while saving fuel to transport this amount of ice out to sea.

According to Mr. Duc, the cost of installing cold-absorbent system is about VND 400 million for ships with capacity of 800-1,200CV, VND 330-350 million for ships with smaller capacity. With this cost, after only a few trips, fishermen can regain their investment and profits will increase significantly after that.

Each ship when installing permeable cold system, Viet Duc Investment Consulting Joint Stock Company will send its staff directly to the technology transfer ship, instructing how to use it for train operators to self-operate the system. .

In order to reduce the post-harvest loss in seafood exploitation to 10% according to the program of the Ministry of Agriculture and Rural Development, by 2020, it is necessary to have preferential policies to quickly test , perfecting and widely applying practice to production.
