Producing fish sauce with solar energy

Shorten fish sauce production time to 6 months, instead of 10-12 months as before. Obtain more than 30% of fish sauce with traditional production. All these benefits are due to . solar energy.

The topic 'Production of solar energy fish sauce' has attracted the attention of numerous visitors at the Demonstration and Connectivity of technology supply and demand in the North Central region in 2012, which took place in the city. Ha Tinh street over the weekend. The project was researched and completed by Mr. Le Van Danh, the Center for Advanced Science and Technology Application of Ha Tinh.

More production time

Engineer Le Van Danh said that the technological process is basically the same as the traditional sauce making process, except that the process of turning and roasting and drying will not use the traditional fuel but use the heat from the plates. solar collector. This solution has an optimal substitute for many main stages of the fish sauce production process (roasting, stirring, filtering).

The new process is done as follows: in the morning, people will turn on the pump, the fish sauce system will go through the solar heat-radiating system, from here, the fish sauce is increased to the optimal temperature. This process is carried out continuously, brightly, and in a short way, so the labor cost is also reduced because there is not much need for the islanders. Nearly all stages are automated. Due to the active heat source, the system also helps to process fish sauce even in the cold rainy season.

The most outstanding advantage of this technology compared to traditional technology is the reduction of fish sauce production time by half. Besides, with solar collector plate, the production stage will skip the opening of the compost bin, so it will not evaporate, the quality of fish sauce so it will be more delicious and less draining. According to calculations, the amount of fish sauce is 30% more than the traditional stage and maximized by the optimal temperature. It is noticeable that this process is very clean, does not pollute the environment. Another advantage is the automation process so the stages are less directly affected by rudimentary tools such as stirring shovel, ladle . so the food safety and hygiene are also more assured.

Changing production practices

Ms. Tran Thi Thuc, Chairman of the cooperative of Bac Hai fish sauce processing, Ky Xuan commune, Ky Anh district, Ha Tinh province, the pilot unit to implement this fish sauce production process cheerfully said, the production technology Solar energy fish sauce has really changed the way of production so long, and importantly, has helped increase productivity and product quality. Ms Thuc said, at the beginning, each laborer reached 800,000 VND / month, after acquiring this technology, after deducting production costs, the income increased by 1.5-2 million VND / month.

Taking visitors to visit the production model, Ms Thuc said, if before, the stage in the fish sauce pond requires a lot of workers but now only 1-2 people are enough. A supervisor, a system operator according to the specified time.

The production time of fish sauce is shortened to 6 months instead of 10-12 months as before. More importantly, the installation of a solar heating system is simple and easy to operate, according to Ms Thuc: 'Anyone can do it'.

Le Van Danh said that after the success of the pilot model at Bac Hai Fish Sauce Processing Cooperative, many people have come to apply for this new technology. The expectation of the research team is to change traditional fish sauce practices, instead applying a new production process. To do this, Ha Tinh Center for Advancement of Science and Technology application continues to research to improve production technology, along with the technology demonstration to producers.
