How to ensure high stability during feed storage?

The working principle of pellet feed cooler is based on countercurrent heat exchange technology, which is to directly and effectively exchange heat between high-temperature and high-humidity pellet feed and cold air, so as to achieve rapid cooling and dehumidification. Specifically, the high-temperature pellet feed that has just been pressed by the pellet mill enters the cooling chamber of the cooler through a specific conveying device. In the cooling chamber, the cold air is driven by the fan and contacts the pellet feed from bottom to top in countercurrent, taking away heat and excess moisture. This process not only quickly reduces the temperature of the feed, but also adjusts the humidity of the feed to achieve the ideal state for storage.

In terms of technical characteristics, counterflow pellet feed coolers usually use vibrating or rotary feeding mechanisms to ensure that the pellet feed is evenly distributed in the cooling chamber and improve the cooling efficiency. At the same time, temperature sensors and hygrometers are often provided at the outlet of the cooler to monitor the temperature and humidity of the feed in real time to ensure that the cooling effect meets the preset standards. In addition, some advanced coolers are also equipped with automatic control systems that can automatically adjust the cooling time and wind speed according to the type and specification of the feed to achieve the best cooling effect.

The pellet feed that has been cooled shows higher stability during storage, and this improvement is mainly reflected in the following aspects:
The temperature of the cooled feed is close to room temperature, which is crucial for the long-term storage of the feed. Feed in a high temperature environment is prone to heat stress, resulting in loss of nutrients and changes in physical properties. The feed that has been cooled has a moderate temperature, which can effectively avoid the quality degradation caused by heat stress.

Humidity is another key factor affecting the storage stability of feed. A high humidity environment easily causes the feed to absorb water and agglomerate, which not only affects the appearance and fluidity of the feed, but also may cause local concentration or loss of nutrients. The pellet feed cooler adjusts the humidity of the feed to an appropriate range through effective dehumidification treatment, greatly reducing the risk of feed agglomeration due to a high humidity environment.

The moisture content in the feed is one of the decisive factors affecting its storage period. Excessive moisture content not only causes the feed to deteriorate, but also may become a hotbed for mold growth. Cooling not only reduces the temperature of the feed, but also helps to reduce the moisture content in it, further inhibiting the growth of mold and the deterioration of the feed.

After the feed is cooled, its temperature, humidity and moisture content are all in the ideal state for storage, which not only improves the feed's readiness and palatability, but also significantly extends the feed's shelf life. For feed producers, this means higher product quality and longer sales cycles, which brings better economic benefits.

In practical applications, pellet feed coolers have shown many advantages, but they also face some challenges. In terms of advantages, the cooler can significantly improve the storage stability of the feed, reduce returns and complaints due to quality degradation, and improve customer satisfaction. At the same time, the cooled feed is easier to package and transport, reducing logistics costs. In addition, the application of automated control systems makes the cooling process more efficient and accurate, reducing labor costs.

However, challenges cannot be ignored. The design and manufacture of pellet feed coolers require high-precision processes and technologies to ensure their cooling effect and stability. Different types of feed have different requirements for cooling conditions, and the equipment needs to be flexible to adapt to different needs. The heat and moisture generated during the cooling process need to be effectively discharged to avoid adverse effects on the environment and equipment.

With the continuous development of the feed industry and the continuous advancement of technology, pellet feed coolers are developing in a more efficient, intelligent and environmentally friendly direction. On the one hand, the cooling efficiency and energy-saving performance of the cooler will be further improved to meet the needs of large-scale production. On the other hand, the application of intelligent technology will make the cooling process more precise and controllable, reducing errors caused by human factors. In addition, the application of environmentally friendly materials and the effective treatment of waste heat and waste gas will also become an important trend in the development of coolers in the future.

From the perspective of market demand, with the intensification of competition in the feed industry and the improvement of consumers' requirements for feed quality, the market demand for pellet feed coolers will continue to grow. Especially in areas with high requirements for feed storage stability, such as animal husbandry and aquaculture, the application of coolers will be more extensive.
