The invention belongs to the field of licorice, wheat and jujube soup preparation processes, and particularly relates to a licorice, wheat and jujube soup preparation process and production equipment, S1, 50 kg of licorice, 100 kg of wheat and 150 kg of jujube are extracted by dry weight, the raw materials are mixed together, the mixture is put into a mixer, water with the weight 8 times that of the medicinal materials is added, boiling extraction is performed twice, an extracting solution is filtered by a 200-mesh sieve, and a filtrate is obtained; s2, concentrating the filtrate under reduced pressure in an environment with the vacuum degree of-0.06 Mpa and the temperature of 70 DEG C until the relative density is 1.20-1.25 (50 DEG C) and the water amount is 8 times that of the filtrate; the chlorophyll derivative (CPD) separated from the mixed light wheat silkworm excrement has an inhibition effect on in-vitro liver cancer tissue culture cells, in-vitro tests show that 0.04 g (crude drug) ml or 0.01 g (crude drug)/ml of silkworm excrement water extract has an anti-bovine thrombin effect, the coagulation time of human fibrin can be remarkably prolonged, and anxiety depression is inhibited.
