The bamboo chips for pulping as renewable green resources are one of the dominant raw materials for sustainable development in the papermaking field. The stable raw material quality, the orderly supply of the raw material quantity and the green and environment-friendly production process are important problems concerned by the bamboo pulp papermaking industry and key factors for restricting the bottleneck capacity, so that intensive storage, normalized drying and mechanized supply after the bamboo pulp is cut between the materials is an ideal operation mode for going through a modern development road. The existing production technology of bamboo pulp paper mill requires that the size of bamboo chip raw materials is small enough, the bamboo chips for industrial paper making are naturally stacked in the open air in a storage mode, the natural stacking and storage not only causes incomplete abandonment and waste of byproduct resources such as starch, saccharides and the like in bamboo materials, but also has low utilization rate of storage space. The storage cage is used for storing raw materials, the uniformity of the quality of the raw materials is kept to a great extent, so that the turnover rate and the utilization rate of a field are improved, the effect of supplying the raw materials in order in a standardized and stabilized mode can be achieved, and meanwhile, the production capacity is improved, and the quality is stabilized. The storage of the bamboo pulp material is an intermediate link for connecting the bamboo forest and downstream processing, and in terms of cost, when the demand is large, the price of the raw material is difficult to avoid fluctuation, and the bamboo which is not utilized in time plays a positive role in stabilizing the price of the raw material, ensuring the stability of supply and demand and the like. However, the existing storage form is simple and extensive, the resource loss is serious in the natural degradation process, the quality loss is generally 3% -5%, and the raw material uniformity of the bamboo chip storage yard is poor, so how to establish the standardization and intensive stacking of drying collection and raw material storage through a new storage facility becomes a key point and a hot point of research.
During natural storage, the bamboo is likely to be exposed to continuous weather of overcast and rainy, the moisture content of the raw materials is uneven due to poor drying conditions of the bamboo, the temperature of the center of the bamboo chip pile is increased, the humidity of the bamboo chip pile is increased, and mildew, insect pests and other phenomena are easy to occur during storage. At present, equipment for storing bamboo chips for bamboo pulp and a technology for drying materials for the papermaking industry are lacked in the market, and meanwhile, the temperature and the humidity inside a bamboo chip stack cannot be regulated and controlled by means of the circulation of raw materials and external air flow, so that the natural degradation degree difference of the bamboo chips at different positions is large, and further, the energy consumption is difficult to keep uniform in the cooking and delignification process.
