The present invention relates to a process of extracting haw pits by dry distillation and the device used therein. The process includes the following steps: removing the impurities of haw pits and drying them; immersing haw pits in water and then dripping and charging the dried pit into the furnace for dry distillation; gradually raising the temperature and dry distilling the haw pits at two temperature ranges of 105-195° C. and 305-380° C. respectively and collecting the distillate; mixing together the distillate, allowing them to separate into layers by specific gravity difference and separating out the final brownish red transparent liquor by siphon. The method of the present invention can provide high yield of extraction and the present device is simple in structure. Further, the present invention is easy to be employed on the industrial scale.
A method for extracting liquor from haw pits by dry distillation, comprising the following steps:
A device for dry distillation of haw pits, which substantially consists of furnace body, porous inner pipe, eduction pipe, condensing pipe and condenser, which is characterized in that, the said porous inner pipe was inserted into the haw pits and the other end of the porous inner pipe was connected to the eduction pipe, and the eduction pipe was connected to the condensing pipe, in such a way, a passage was formed by the inner pipe, the eduction pipe and the condensing pipe, and through the said passage, the distillate obtained by the dry distillation can flow out of the device.
