How does Freeze-Drying Equipment for Aquatic Feed affect the nutritional value of aquatic feed?

Freeze-drying technology, as an efficient water removal method, can remove water by sublimation at low temperature, avoiding the damage of heat-sensitive nutrients in aquatic feed caused by high temperature process. Compared with traditional drying methods, Freeze-Drying Equipment for Aquatic Feed can significantly maintain the nutritional value of aquatic feed. The specific effects are as follows:

(1) Retaining protein and amino acids

Protein in aquatic feed is the main source of growth for fish and other aquatic animals. In the traditional heat drying process, protein is easily denatured at high temperature, resulting in the loss of amino acids and decreased digestion and absorption rate. Freeze drying removes water under low temperature and low pressure conditions, which can effectively avoid protein denaturation, thereby preserving its original structure and biological activity to the greatest extent. Maintaining the integrity of protein helps aquatic animals to better digest and absorb, thereby improving growth rate and health.

(2) Retaining vitamins and minerals

Aquatic feeds are rich in water-soluble vitamins (such as B vitamins and vitamin C) and fat-soluble vitamins (such as vitamins A, D, and E). These vitamins are easily degraded during the traditional hot air drying process, resulting in a decrease in their nutritional value. Freeze drying can effectively retain these sensitive components by avoiding high temperature exposure. Aquatic feeds processed by freeze drying technology have obvious advantages in retaining vitamins and minerals, which is crucial for improving the immunity of aquatic animals and promoting their growth and reproduction.

(3) Preventing fat oxidation

Aquatic feeds usually contain a high fat content (especially fish meal and fish oil rich in omega-3 fatty acids). Fat is easily oxidized under the action of high temperature and oxygen, producing harmful peroxides and free radicals, which reduce the nutritional value of the feed and affect the health of aquatic animals. Freeze drying equipment reduces the occurrence of oxidation reactions by performing low-temperature treatment in a vacuum environment, thereby effectively retaining unsaturated fatty acids in aquatic feeds, especially omega-3 fatty acids that are beneficial to the health of aquatic animals.

(4) Improving the bioavailability of aquatic feed

Freeze drying not only preserves the nutrients in aquatic feed, but also changes the structure of the feed, making it easier for aquatic animals to digest and absorb. Traditional drying methods may cause the feed particles to harden, reducing their efficiency in being ingested by animals. Freeze drying improves the palatability and digestibility of the feed by maintaining the cell structure and particle morphology of the feed.

What differences should be paid attention to when handling different types of aquatic feed?

Different types of aquatic feed vary greatly in terms of raw material composition, water content, fat content, etc., which requires freeze drying equipment to be able to adjust accordingly according to specific production needs. The flexibility of Freeze-Drying Equipment for Aquatic Feed enables it to cope with these differences, which are as follows:

(1) Differences between low-fat and high-fat feed

Low-fat feed (such as plant-based feed) and high-fat feed (such as fish meal or feed with high oil content) have different handling requirements during the freeze drying process. High-fat feeds are prone to oil precipitation and aggregation during freeze drying, which may cause uneven drying of feed particles and even affect their quality. Therefore, freeze drying equipment needs to precisely control temperature, pressure and time to prevent oxidation or destruction of fat components during the drying process. In contrast, low-fat feeds have a lower risk of oxidation during drying due to their lower fat content, and the equipment can use a higher sublimation temperature to improve drying efficiency.

(2) Differences in particle morphology and particle size

Different types of aquatic feeds have different particle morphologies and particle sizes. For example, feeds with larger particles (such as some granular fish feeds) may require longer sublimation times and lower heating rates during freeze drying to ensure that the internal moisture can be evenly removed. Small particle feeds may require more efficient drying parameters to avoid over-drying or structural damage of the particles. Freeze drying equipment needs to adjust drying conditions according to the characteristics of different particles to ensure uniform drying effects.

(3) Differences in water-soluble components

Some aquatic feeds are rich in water-soluble components (such as amino acids, minerals and B vitamins, etc.), which may be destroyed by changes in temperature and humidity during freeze drying. Therefore, freeze-drying equipment must pay special attention to temperature and time control when processing these ingredients to avoid the loss of ingredients. For these highly water-soluble ingredients, the heating rate during the freeze-drying process should be kept low to ensure the stability of the ingredients.

(4) Differences between compound feed and single-ingredient feed

Compound feed is usually made from a mixture of multiple raw materials (such as fish meal, plant meal, animal fat, etc.). When freeze-drying, it is necessary to adjust the temperature according to the physical and chemical properties of different ingredients. For example, the freeze-drying requirements of protein and fat are different from those of plant fiber or minerals. Freeze-drying equipment needs to flexibly adjust temperature, pressure and humidity to ensure that all ingredients are dried evenly and effectively.
