The invention relates to a leaf thread material feeding process and equipment, which belong to the technical field of tobacco processing. The invention is characterized in that the leaf thread feeding process sequentially comprises the working procedures of thread cutting, temperature increasing and humidifying loosening, air separation loosening and material feeding. The equipment applicable to the process comprises a thread cutting machine, a quantitative material feeding machine, a vibration vulcanization bed, an air separation loosening device and a vertical material feeding machine which are sequentially ranged, wherein each equipment is connected through material conveying mechanisms, the vertical material feeding machine comprises a material feeding cavity, a material inlet airlock and a material outlet airlock are respectively arranged on the top and the bottom of the material feeding cavity, a material scattering mechanism is fixed on the upper part of the material feeding cavity, a material liquid atomizing system is communicated with the material feeding cavity through an air inlet pipe and a air return pipe of a hot air circulation system, and a sealed cyclic feeding system is formed. The process and the equipment can solve the problems of large thread cutting pulverization products of low-water-content tobacco flakes and material feeding aggregation of tobacco threads, the material liquid atomizing effect is good, the material liquid absorption velocity by the tobacco threads is high, the material feeding uniformity and the effectiveness are improved, in addition, the material storing time after the material feeding is shortened, and the production efficiency is high.
