Description

A drying device for grass granule production

Technical Field

The utility model relates to the technical field of forage grass granule processing devices, in particular to a drying device for grass granule production.

Background

With the continuous development of animal husbandry, forage grass pellets are widely used as a high-quality feed form. The forage grass particles have the advantages of small volume, high density, convenient storage and transportation, and the like, can effectively reduce the nutrition loss of forage grass in the storage process, and improve the utilization rate of the forage grass. In the production of fodder particles, drying is a critical element which directly affects the quality and shelf life of the fodder particles.

The traditional forage grass granule drying equipment mainly comprises an oven, a tunnel dryer and the like. The oven drying is to put the fodder particles in a closed box, and evaporate water in the fodder particles by heating air. In the drying process, because the forage grass particles are in a static state, hot air is difficult to uniformly contact each particle, so that the drying is uneven, part of the particles may be excessively dried, the loss of nutrient components is serious, and part of the particles are insufficiently dried and are easy to mold and deteriorate. Moreover, the space of the oven is limited, the single drying amount is less, the drying efficiency is low, and the requirement of mass production is difficult to meet.

The tunnel drier is to make the fodder particles move slowly on the conveyor belt and dry by the hot air in the tunnel. Although this approach solves the problem of small single drying of the oven to a certain extent, as the forage particles are accumulated on the conveyor belt, uneven heat distribution occurs when the hot air penetrates the particle layer, the particles near the hot air inlet are dried quickly, the particles inside and at the bottom are dried slowly, and the defect of uneven drying also exists.

In summary, the conventional forage granule drying equipment has obvious defects in terms of drying uniformity and drying efficiency, and is difficult to meet the requirements of modern animal husbandry on efficient and high-quality production of forage granules. Accordingly, there is a need to develop a new type of drying apparatus for grass pellet production that overcomes the drawbacks of the prior art.
