Alfalfa is rich in high-quality protein, is a kind of high quality livestock feed. The newly harvested alfalfa has a high moisture content, which is not easy to storage. Drying alfalfa can greatly preserve its protein and vitamins, prolong storage time, and improve economic benefits. However, there are many kinds of alfalfa drying machines on the market, and the prices of different types of machines vary greatly. How to choose?

Detailed explanation of the three mainstream types of alfalfa dryers

Rotary dryer

The alfalfa rotary dryer adopts a horizontal drum with a spiral conveyor shaft or impeller installed inside. The material is lifted and falls inside the drum, forming air convection and improving heat exchange efficiency, thereby achieving rapid and uniform drying. The rotary dryer has a large processing capacity and is suitable for continuous and large-scale production. It has strong adaptability to material moisture content and can directly process high humidity alfalfa (65% -75%) with a moisture content of 65-75%. The structure is mature, the operation is stable, and the maintenance cost is relatively low. The overall investment is moderate.

Belt dryer

The alfalfa mesh belt dryer adopts heat-resistant stainless steel mesh belt or conveyor belt, and the material continuously enters the drying room through the belt conveyor system. Hot air flows inside the drying room, and materials are dried on the mesh belt through natural convection. Due to the use of low-temperature drying, the mesh belt dryer can preserve the color, protein, and nutritional components of alfalfa to the maximum extent possible. The drying process is highly controllable, the product quality is good, and the degree of automation is high, making it suitable for fine processing. The overall investment is moderate to high.

Bale Dryer

The alfalfa hay bale dryer is designed specifically for hay bales and is mainly a large vertical or horizontal drying room. By circulating hot air and penetrating the inside of the bundle, rapid drying is achieved to prevent mold growth. Solved the problems of difficult drying and uneven internal humidity in traditional hay bales, greatly improving the storage efficiency of silage or hay. It can directly dry whole bales of alfalfa, effectively solving the problems of high moisture and easy mold inside the bales. The drying is uniform, greatly improving storage safety and transportation stability. The unit processing investment is relatively high, but the supporting facilities are flexible and do not require complex pre-processing.

Applications

Rotary dryer

Suitable for the production of alfalfa pellets, grass powder processing plants, feed plants, and export grade alfalfa hay processing projects.

Mesh belt dryer

Suitable for producing high-end feed and pet feed using alfalfa, with high requirements for appearance and nutritional retention.

Bale dryer

Suitable for processing hay for pasture and personal use, exporting alfalfa bales, and long-term storage projects.

The above is an introduction and price analysis of common types of alfalfa drying equipment in industry. It is necessary to choose the appropriate type of alfalfa dryer according to the actual situation. Zhengzhou Jiutian has over 20 years of experience in alfalfa drying, with equipment exported to more than 100 countries. Please feel free to inquire at any time!
