With the continuous development of the domestic fishmeal industry, the number of fishmeal factories is also gradually increasing. The rapid development of fishmeal processing industry has also brought a series of environmental problems. Some small-scale fishmeal processing factories have relatively backward equipment and processes. The operation and management are not standardized, and the odor pollution is more obvious. In recent years, environmental complaints have occurred frequently due to fishmeal processing.

The source of odor from fish meal processing

Fish meal processing is a process of high-temperature steam cooking, pressing, drying, and crushing of fish and shrimp raw materials or scraps, and then making fish meal. These processes will generate a series of sewage and waste gas that need to be treated.

The main sources of odor are:

Organized emission sources: high-temperature cooking exhaust gas of wet drying furnace, drying exhaust gas of dryer;

Unorganized emission sources: raw material storage yard, waste water, waste water treatment station, raw material transfer in production, etc.

Among them, high-temperature cooking, raw material storage yard, and raw material transfer are the main sources of odor.

Malodorous gas composition analysis

The odorous gas produced during the processing of fish meal has complex chemical components and many influencing factors. There is no comprehensive composition analysis data yet. The known components are mainly acrolein, butyric acid and valeric acid, oil degradation products, and hydrogen sulfide. , ammonia, and trimethylamine. It will even produce some toxic substances, such as hydrogen sulfide, so it is necessary to reduce emissions and control odors!

Odor characteristics of fish meal processing

Regarding the waste gas generated in the processing of fishmeal, we found that although the composition of fishmeal odor is relatively complex, it also has the following characteristics: easy to collect, low odor concentration, and good odor biochemical properties.

Fish meal processing odor control method

There are many ways to control the odor of fish meal processing:

Oxidative combustion deodorization

Odor is oxidized and catalytically burned by utilizing the reducing properties of most odorous substances. The former can sometimes recover heat, and the instability of production in small and medium-sized fish meal factories makes heat recovery more difficult; the latter can be operated at low temperature, but the catalyst is easily poisoned. , block, use less. It is characterized by high efficiency and high cost.

Adsorption and deodorization

Adsorbent activated carbon, activated clay and other odorous substances are used to adsorb odorous substances, with high deodorization efficiency and low power consumption. It is suitable for waste gas with low odor concentration and no particles, and is not suitable for fish meal production.

Chemical deodorization

Borrowing the chemical unit operation theory, it is suitable for the treatment of waste gas with high concentration of odor pollutants. The technology is mature, the operation is stable, the area is small, and the treatment efficiency is high.

Water-soluble deodorant

Dissolving odorous gas with water to remove odor is characterized by lower investment and operating costs, but the purification effect is not good, and the amount of wastewater produced is too large.

Biological deodorization According to the characteristics of fishmeal waste gas, combined with the advantages of chemical deodorization and adsorption deodorization, the biological trickling filtration technology is especially suitable for the waste gas pollution of fishmeal processing plants, which can improve the deodorization efficiency of fishmeal processing and reduce operating costs. For the purpose of producing fish meal with complex odor components, this method is applicable.

Fish meal production is a crucial process in the animal feed industry, providing a high-protein ingredient for livestock, poultry, and aquaculture feeds. One of the essential steps in fish meal production is the concentration of protein water. This step is vital for enhancing the nutritional value of the final product and ensuring efficient resource utilization. In this article, we will explore the protein water concentration process in fish meal production, highlighting its significance and the techniques involved.

What is Protein Water Concentration in Fish Meal Production?

Protein water, also known as stickwater, is a by-product of the fish meal production process. It contains dissolved proteins, peptides, amino acids, and other nutrients extracted during the cooking and pressing stages of fish meal production. Concentrating this protein water is essential to reclaim valuable nutrients and improve the overall yield and quality of fish meal.

Techniques for Protein Water Concentration

Several methods are employed in the fish meal industry to concentrate protein water effectively. Here are the most commonly used techniques:

Evaporation:

Multi-Effect Evaporators: This method uses multiple stages of evaporation to concentrate the protein water. The multi-effect evaporators are efficient and energy-saving, making them a popular choice in fish meal plants. The process involves heating the protein water to evaporate the water content, leaving behind concentrated protein-rich liquid.

Centrifugation:

Decanter Centrifuges: These devices use high-speed rotation to separate solids and liquids based on density. In fish meal production, decanter centrifuges effectively concentrate protein water by separating the solids (proteins) from the liquid. This method ensures a high recovery rate of proteins.

Membrane Filtration:

Ultrafiltration and Reverse Osmosis: Membrane filtration techniques such as ultrafiltration and reverse osmosis are used to concentrate protein water by allowing only water and small molecules to pass through the membrane, retaining the larger protein molecules. This method is effective in producing high-purity protein concentrates.

Benefits of Protein Water Concentration

The concentration of protein water in fish meal production offers several advantages:

Nutrient Recovery: Concentrating protein water helps recover valuable nutrients that would otherwise be lost. This enhances the nutritional profile of the fish meal, making it a more effective feed ingredient.

Resource Efficiency: By concentrating protein water, fish meal plants can maximize the use of raw materials, reducing waste and improving overall efficiency. This aligns with sustainable production practices and environmental conservation.

Cost-Effectiveness: Efficient protein water concentration processes can lead to cost savings by reducing the need for additional raw materials and lowering disposal costs for waste streams.

Improved Product Quality: Concentrated protein water can be added back into the fish meal, enhancing its protein content and overall quality. This results in a superior product that meets the nutritional requirements of animal feeds.

Application in Fish Meal Plants

Fish meal plants around the world utilize advanced technologies to concentrate protein water effectively. For instance, multi-effect evaporators and decanter centrifuges are widely implemented due to their efficiency and reliability. Additionally, membrane filtration systems are gaining popularity for their ability to produce high-purity protein concentrates.
