When drying the leather, in addition to paying attention to the quality of the leather, how to save energy and reduce the enterprise cost is also undoubtedly the important considerations for the leather enterprise. We are mainly introduce the key nodes of the leather drying process:
- The dried leather after tanning and fatliquoring generally contains over60% of water content, however, the moisture content of the finished leather material is required to be 12-18%. Wet leather is of high ductility, and the leather fibers has not been shaped, which cannot conduct mechanical works, whereas dried leather, whose skin fiber has been shaped, are easy for collection and cleaning.
- Hanging the leather on a rod or rope, controlling the moisture content of the leather at 30-40% before drying, and send it to the drying room.
- The Shuntec heat pump drying room is equipped with heating systems, heat dissipation system, blasting system, and air supply facilities, which will not be directly affected by the environment and climate. The main characteristic of Shuntec drying equipment is high efficiency.
- Making the moisture distribution in the leather skin becomes more even, and the dried leather should be stacked for over 12 hours in order to balance the moisture content in the leather skin.
Summary: by using heat pump dryer for drying the leather could make the drying temperature relatively uniform, and there will be no pollution to be discharged during the drying process. No personnel are need to guard if you chose Shuntec dryer, as they are equipped with a microcomputer control system to control the operation of the dryer equipment. In addition, the whole drying process is intelligently.
