The invention discloses a preparation process of traditional Chinese medicine residue machine-made charcoal. The preparation process comprises the following production processes for the machine-made charcoal: preparation of raw materials, rod manufacturing, carbonization, dust and smoke treatment, selection and primary treatment of the raw materials, forming and drying treatment of the raw materials, curing and forming treatment, carbonization cooling and forming treatment and dust falling treatment. The specific steps are as follows: step 1, selection and primary treatment of raw materials; step 2, forming and drying treatment of the raw materials; step 3, curing and forming treatment; step 4, carbonization cooling and forming treatment; and step 5, dust falling treatment. The drying, forming and carbonation treatment can be carried out on the traditional Chinese medicine residues, so that the traditional Chinese medicine residues can become a good energy, and the utilization rate ofthe traditional Chinese medicine residues is improved.
