AI Technical Summary
Existing drying equipment is prone to damaging crops under normal pressure, while vacuum drying equipment has large air leakage and high energy consumption, resulting in high drying costs and the inability to achieve continuous cycle drying.
A multi-effect negative pressure continuous drying device is designed, which adopts staggered tubular and trough heat exchange mechanisms to form a continuous folding heat medium and steam flow channel. It combines high temperature, medium temperature and low temperature heat energy for multiple uses, and uses jet tubes to form traction force to realize continuous drying of materials and recycling of heat energy.
It reduces the energy consumption of drying equipment, improves the drying effect, realizes continuous cycle drying, reduces costs, and improves thermal efficiency and economic benefits.
