Technical requirements for rotary cut veneer dryer

It is understood that the rotary veneer dryer is a continuous boring equipment for mass production, which is used for the boring of sheet, strip, granular and some paste materials with good air permeability. It is especially suitable for high moisture content and heat sensitive materials such as traditional Chinese medicine pieces. It has the advantages of high drying rate, high evaporation intensity and good product quality. According to the different structure, the mesh belt dryer can be divided into many types. Common such as single-stage mesh belt dryer, multi-stage mesh belt dryer, multi-layer mesh belt dryer, impact mesh belt dryer and so on. Meanwhile, the working principle of the single-stage mesh belt dryer is that the dry material is evenly distributed to the mesh belt from the feeding end through the feeding device. The dryer box is generally divided into several units in order to independently control the operating parameters and optimize the operation. And there is a barrier section between the boring section, in which no boring medium cycle.

It is reported that the multi-stage mesh belt dryer is essentially composed of several single-stage mesh belt dryer in series, and its operating principle is the same as that of single-stage mesh belt dryer. Multi-layer mesh belt dryer is often used in the field of low boring speed requirements, long boring time, and stable process operating conditions during the whole boring process. It is reported that the multi-layer mesh belt dryer is widely used in dry grain materials because of its dry and uniform material, small footprint and simple structure. However, due to the repeated loading and unloading in the operation, it is not suitable for dry viscous and fragile materials. The impact mesh belt dryer is generally composed of two conveyor mesh belts, which can be separated into unit segments for independent control. The working principle is that after the dry medium is humidified, part of it is discharged, and the other part is returned to the fresh dry medium and then recycled. It is generally suitable for drying dry fabrics, tobacco leaves, surface coating of substrates and other flaky materials.

Now, veneer dryer in traditional Chinese medicine, dehydrated vegetables, grain boring and other fields with a wide range of use, in recent years with the increasing competition in the market, dryer equipment manufacturers are necessary to break the tradition, speed up the renewal of products promotion, in order to improve the core competitiveness of products in the market.
