The tea re-humidification machine is an integral component of the tea production line. This hygienic production line addresses the issues of poor sanitary conditions and low levels of automation in the processing of white tea, effectively reducing the physical strain on tea pan operators, lowering labour costs and enabling hygienic production. This production line utilises a touchscreen and electrical controls to enable automatic feeding and tea discharge, facilitating continuous white tea processing and making the production process faster, more efficient and more hygienic. In actual production, this production line offers high practicality, reliability and ease of maintenance.
