The Zhenhai County Specialty Products Company in Zhejiang Province learned advanced technology in the field, and through many experiments, it successfully reformed and promoted new tea drying stoves throughout the county. It was measured at the on-site appraisal meeting held on April 28. The tea consumption of 58 kilograms of coal is 50% less than the original 100 pounds, and is lower than the coal consumption in the advanced regions (60 pounds). The benefit is very significant, and it has been well received by tea experts and tea farmers.
