British mechanic dose and super cheap fish meal line

In order to take advantage of trash fish and trash fish (often discarded by fishermen in the sea), a mechanic in Ca Mau has successfully fabricated the fishmeal production line (previously imported from abroad at an expensive price). 3).

Fix . try

Song Doc is a large estuary in Ca Mau with nearly 1,000 fishing vessels carrying on land no less than 70,000 tons of fish and shrimp each year. That is not to mention a large amount of trash fish carrying heavy ships but not sold but fishermen leave on the sea.

Taking advantage of by-products from fishing, about ten years ago at this seaport, a fish meal processing plant named Sing Viet was raised.

The story began when Sing Viet imported equipment from Thailand (the fish meal processing line at that time in Southeast Asia, no country produced outside Thailand). Therefore, when the equipment arrives at Song Doc, your water engineers also follow to assemble because only they understand the 'core' of the technology line that is considered ' advanced ' at this time. . There are only a few engineers in the engineering force, so there is a need for skilled mechanic and electromechanical workers to do the extra work. Dang Loi was invited to assemble 'whisker' for the first fishmeal processing line at this seaport.

In Song Doc town (Tran Van Thoi district), Dang Loi is considered by everyone to be a mechanic, repairing young ships but highly skilled. For 'old-fashioned' train machines , without spare parts when damaged, he could 'make things' to assemble, helping the machine run smoothly . Therefore, before each trip to the sea Song Doc fishermen all give ships to Loi . 'examination'.

Loi remembers: 'I heard engineers tell each other that this line was connected by Thailand and Denmark, so the workers came here to assemble, each one only knew one stage; If only I was a country mechanic. However, when I heard them laugh, I was angry, thinking that I would make a better fish meal processing machine from foreign countries. '

For a few years, the fishmeal production line of Singaporean investment company in Song Doc has a bad problem. Contacting foreign partners to hire Thai engineers to repair at high prices but still cannot. Hearing this news, Dang Loi came to Sing Viet to "ask" to "examine" the whole line. Initially, the factory owner did not give, but persuaded forever, Loi was finally allowed to "fix it" and he quickly overcome the problem in a very short time.

. Come to work

The successful repair of fishmeal production line has helped Dang Loi get excited because he has been in contact with the thermal oil pump system, gearbox, furnace . of the massive machinery system. Also this time he found himself no longer "self-love" half because many people looked at him with admiring expressions.

One day in early 2003, Loi suddenly discussed with his wife to collect money to make an improved fishmeal production line. Supported by his wife, the next day Loi picked up the high-speed train to Ca Mau to buy all kinds of iron and steel and together with the mechanic's group of workers brought his name to draw a drawing, design a fish meal production line.

During the study of the whole chain to download and reduce investment costs, reduce input costs when loading materials ., Loi received an important contract to repair the heat transfer oil pipe for the fish meal factory. Ganh Hao (Bac Lieu) with a price of only VND 145 million. This factory has an investment value of over 7 billion VND from modern Japanese technology, but the heat pipe is damaged after the warranty expires (there is no replacement in the country).

Before signing the contract with Dang Loi, the plant manager contacted nearly a dozen famous units in the Southern mechanical industry but only two units responded, with the installation price double that of Loi's contract. .

Receiving the contract, Dang Loi and his colleagues had to "fight" both mind and force with the giant spring truss 4m long, nearly 1m in diameter, made of round iron pipe with a diameter of 102mm, 4mm thick. After careful research, Dang Loi made a gantry to roll each iron pipe straight into circles and welded it again. The rest, Loi works as fast as the hand; he was absolutely successful.

With this success, Dang Loi was more exposed to the fish meal production line and became famous in the mechanical village in Ca Mau. From here, he realized the operating principle of the entire chain, especially the method of reducing the investment costs of machinery and reducing production costs to increase profits.

Dang Loi said: 'I look at their technology and improve it to make it more convenient to produce quality products that cannot be' imitated '. Through research, I found that at the stage of cooling the product according to Thai technology, it is necessary to use the motor to pump water through the cooling basin and then use the conveyor to pass the tank. If going around like that would be very expensive, I put the whole step through the tank, but I designed an extra wrap around the swirl to cool it down during the conveyor process'.

With this approach, Dang Loi's fishmeal production line saves fuel in the washing pump, while saving electricity because no electric motor is needed.

Success "above expectations"

After many improvements, 'cutting' unnecessary equipment, finally the machine 'made in Song Doc' of Dang Loi should be shaped. In the early days of seeing this chain, everyone thought that it was very different from machines imported from Thailand, and like . 'monsters'.

On the opening of the fishmeal factory, Loi Loi announced that the investment cost was only 800 million dong (1/4 lower than the price of importing equipment abroad), everyone clapped hands. The whole line operates smoothly, does not emit bad smell (a difficult remedy of other factories).

From this success, dozens of partners across the country have come to Dang Loi to contract to assemble fishmeal production lines. He said: 'In addition to factories in Ca Mau, this small mechanical workshop has shipped over 10 assembly lines for fishmeal to be assembled in provinces such as Ben Tre, Ba Ria - Vung Tau, Kien Giang, Da Nang . At present, the average price of an improvement line has a capacity of 80-100 tons / day for about 3.8-4 billion VND. If the equipment is imported from abroad, it will be raised to about 9-10 billion '.

Loi also said that in addition to the improved fishmeal production line, he has just 'invented' successfully the high quality iodized salt production line from the method . producing sand sugar costs only 250 million dong. This line has now been transferred to an iodized salt production company in Bac Lieu with very efficient operation, the salt produced is of superior quality compared to other factories in the region.
