枸杞有很多健康益处,如含有抗氧化剂、肥胖控制和多酚,它有助于降低患心血管疾病的风险。
水是枸杞中各种成分的生化反应所必需的。随着枸杞水分含量的增加,茶叶的变化也会加快。当水分含量在7%以上时,没有保存技术来保持其风味。因此,为了更好的储存和更高的质量,茶需要干燥。经过干燥处理后,枸杞的含水量在4%~6%左右,可以延长其保质期。
枸杞干燥不仅可以去除茶叶中的水分,而且对枸杞的品质也有很大的影响。干燥是控制枸杞中酶活性的关键。干燥过程中会发生化学变化,从而增强茶的色、香、味、形,减少苦味,提高枸杞的品质。
枸杞网带式烘干机适用于块状、条状、片状和颗粒状的商业作物,如:洋葱、大蒜、辣椒、杏子、瓜子、花生、红薯、土豆、木薯、枸杞、红枣、香草、甜瓜、蔬菜、水果等。
枸杞网带式烘干机也可以做茶叶烘干,与微波烘干机相比,容量更大,烘干速度更慢。茶叶可以从料斗通过输送机送到带式干燥机的上层,然后流到带式干燥机底部的卸料窗口。由于每层的传送带可以在一层上进行两次往复干燥,因此获得了宽的干燥区域,实现了紧凑和节省空间的结构。
Materials are uniformly put on the mesh-belt by the feeder. The mesh-belt uses generally 12-60 mesh stainless steel wire net and it is drawn and moved inside the drier by a transmission device. The drier is composed of several units. For each unit, the hot air is circulated separately. Some exhausted gas is discharged with a special moisture elimination blower. The waste gas is controlled through an adjustment valve. The hot air passes through the mesh-belt covered with the material from the top to the bottom or from the bottom to the top and this will complete the heat and mass transfer process. This process will bring the material water away. The mesh-belt moves slowly, running speed can be freely adjusted according to the material temperature. The final products after drying will fall into the material collector continuously. The top and low circulation units can be freely equipped according to the users’ demand. The unit number can be selected according to the demand.
DW series multi-layer belt dryer is a continuous drying equipment for batch production. It is suitable for large-scale production of difficult-to-dry materials with low drying rate. The equipment has compact structure, small floor area, simple operation, convenient maintenance and stable operation.
