Method for extracting bamboo juice

The invention relates to the technical field of bamboo processing and treatment, and discloses a bamboo juice extraction method which comprises the steps that a bamboo chip is taken, the bamboo chip comprises a bamboo wall section and a bamboo joint connected with the bamboo wall section, a pair of pressure faces apply 0.5-6 MPa pressure to the bamboo chip from the bamboo green face side and the tabasheer face side of the bamboo chip, and the bamboo green face side and the tabasheer face side of the bamboo chip are sealed; and the pressure is kept until the water content of the bamboo chips is reduced to 5-15%, the pair of pressure surfaces has the temperature of 120-200 DEG C, and the bamboo juice is collected at the ends of the bamboo chips. The extraction method has the advantages of low-temperature safety, high extraction efficiency and high bamboo juice yield, and the obtained bamboo juice is relatively high in purity and free of impurities; meanwhile, the bamboo obtained after the bamboo juice is extrac
