The purpose of fish meal drying is to remove the moisture of the cooked or crushed fish meal to obtain preliminary coarse fish meal. The drying process and effect of the dryer directly affect the quality and digestibility of the fish meal. Therefore, it is very important to choose the correct drying equipment.
First, choose the type of dryer
At present, there are many types of dryers on the market, mainly indirect drying and direct drying. Different processes include drum dryers, fluidized bed dryers, spray dryers, disc dryers, paddle dryers, coil dryers dryer etc.
vThe application industry of the dryer is very wide, and it can be used in sludge drying, feed drying, distiller's grain drying, starch, fish meal, meat and bone meal and other industries.
In the fishmeal industry, disc dryers and coil dryers are widely used. The processing technology of these two kinds of dryers is similar, and the main difference is that the structure and shape of the dryer are different.
Second, choose the dryer manufacturer
After determining the appropriate type of dryer, the next job is to choose a suitable fishmeal dryer manufacturer. Since the domestic fishmeal processing industry has progressed relatively late compared to foreign countries, the domestic research and development and manufacturing of fishmeal equipment is also relatively late. With the rapid development of the domestic fishmeal industry, the research and development and manufacture of fishmeal production equipment have also achieved unprecedented development.
Our company has been engaged in the research and development and manufacture of fishmeal equipment for many years. The FM series fishmeal dryer launched by our company is well recognized by customers. It adopts unique hidden welding seam design, compact design, larger heat exchange area, and adopts steam indirect drying. Compared with traditional hot air drying, the mass transfer resistance is very small, and the temperature of the exhaust gas is kept above 100 °C, which is easy to be recycled. If it is equipped with condensation, compression and other devices, it can be recycled and reused, so the thermal efficiency is high. In addition, because the heat capacity of steam is 1 times larger than that of air, the consumption of drying medium is significantly reduced, so the unit energy consumption is low. At the same time, it also has a large heat transfer coefficient, a small amount of steam, no danger of explosion and fire, and is conducive to environmental protection and sterilization and disinfection.
Feeds Machinery provides the design, manufacture, installation, commissioning and after-sales maintenance of a complete set of fishmeal and fish oil equipment production lines, and provides customers with complete sewage and waste gas treatment solutions to achieve pollution-free fishmeal industry.
Based on years of R&D and production experience of fishmeal equipment production lines, Feeds Machinery has launched the Fishmeal Process (FMP), a wet-process fishmeal production process, suitable for the production of fishmeal with raw material capacity up to 15 tons/hour and above. The produced fishmeal has better quality, high digestibility, low energy consumption and simple operation. If a complete fishmeal and fish oil production and processing system is adopted, the production capacity can be increased by 5% (the digestibility is increased by 3%), and the whole process can be achieved without pollution.
