How to choose aquatic feed equipment?
Aquatic feed is specially formulated feed for aquaculture, and aquatic feed equipment refers to the processing machinery specifically used to produce such feed. There are various types of aquatic feed with different applications. In terms of shape (feed characteristics), it can be classified into extruded feed, pellet feed, and powdered feed, as well as premixed, compound, and concentrated feed. In terms of application (species being fed), it can be divided into shrimp feed, fish feed, crab feed, etc. The main raw materials for production include grains, oils, fishmeal, etc., with grain raw materials and fishmeal accounting for more than half of the feed cost during the production process.
With the development of China's aquatic feed industry and the continuous emergence of new processing technologies, the quality of aquatic feed has been effectively improved. The special processing techniques for aquatic feed originate from the specific requirements of aquatic feed processing quality, which in turn stem from the physiological characteristics of aquatic animals' feeding, digestion, and absorption.
China has a wide variety of aquaculture species, which can be classified into freshwater and marine species based on water salinity, and into fish, crustaceans, amphibians, reptiles, etc., based on biological classification. According to the different feeding habits of aquatic organisms, aquatic feed can be processed into various forms, such as powdered feed (mostly used for special aquatic species like eels and turtles; before feeding, a certain amount of water is added and mixed into a paste-like consistency using a small ribbon blender), hard pellet feed (suitable for most freshwater fish, marine and freshwater shrimp and crabs, ornamental fish, etc.), extruded feed (mostly used for marine cages, shallow sea mudflats, high-value freshwater fish, ornamental fish, etc., and is recognized as a sustainable and healthy feed), and micro-particle feed (also called starter feed, such as shrimp flakes, mainly used for seedling rearing), among others.
Compared to terrestrial animals, aquatic animals differ in living environment, habits, and physiological functions. Most fish lack a stomach, and even those with a stomach have digestive functions that differ significantly from terrestrial animals. Therefore, the intestine is the main digestive organ for fish and shrimp. The length of the digestive tract determines the ease with which animals utilize nutrients, and its physiological characteristics mean that finer food particles are more conducive to digestion and absorption in aquatic animals. The general differences between aquatic and terrestrial animals are as follows: 1. Aquatic animals live in water throughout their lives, requiring feed with good water stability to prevent nutrient loss and reduce pollution of the aquatic environment; 2. Aquatic animals have shorter digestive tracts, lower digestive enzyme activity, and weaker digestive capacity than terrestrial animals, thus requiring finer grinding of feed ingredients to improve digestion, absorption, and utilization; 3. Different species and growth stages of aquatic animals, due to differences in living habits and feeding behaviors, have varying nutritional requirements and feed form preferences. Therefore, compared to terrestrial animal feed processing, the processing techniques and equipment for aquatic feed differ.
Jinan Datong Machinery Equipment Co., Ltd. has extensive research experience and achievements in industries such as aquaculture, aquatic feed production, and production equipment manufacturing. In the aquatic feed production process, the grinding process is one of the main processes for feed manufacturers. The quality of grinding directly affects related variables such as feed quality and output. The grinding process also depends on the mechanical equipment involved in the grinding procedure. Commonly used feed grinding equipment includes hammer mills, drop-shaped hammer mills, vertical shaft hammer mills, micro mills, and ultra-fine mills. Jinan Langzheng Machinery Equipment Co., Ltd. produces and sells various models and types of food machinery, including one of our innovatively developed and patented complete sets of aquatic feed equipment.
In the actual operation of aquatic feed manufacturers, different feeding targets should choose different aquatic feeds and aquatic feed equipment. For producing aquatic feed, the aquatic feed equipment manufactured by Jinan Datong Machinery is recommended. Datong equipment not only features high cost performance, safety, and efficiency, but also, during the production process of aquatic feed, regardless of the stage in the production process, it can not only maintain the original physical state of the raw materials but also produce aquatic feed varieties that are rich in nutrition and diverse in shape.
In recent years, the aquatic feed industry has shown a trend of high growth and high profits, attracting more and more small and medium-sized enterprises to join, but competition is also intensifying. The entry barrier for small and medium-sized enterprises is relatively low, but to thrive in the industry, they must not only rely on advanced business concepts, future planning, and the professionalism and dedication of management personnel, but also choose brand aquatic feed equipment that can be used long-term and offers continuous innovative services. Jinan Datong Machinery Co., Ltd. aims to serve food and feed producers, growing and developing together with entrepreneurs through professional industry experience, high-quality mechanical equipment, and thoughtful services.
