Concentrated fruit juice production line and technological process thereof

The invention relates to a concentrated fruit juice production line and a technological process thereof. The concentrated fruit juice production line comprises an enzymolysis tank, the enzymolysis tank comprises a tank body and a bottom plate, the upper end of the tank body is fixedly connected with a supporting frame, the supporting frame is fixedly provided with a first motor, the first motor is fixedly provided with a stirring shaft, the stirring shaft is slidably connected with an adsorption disc, the adsorption disc is detachably connected with a plurality of sleeves in the circumferential direction, a plurality of through holes are formed in the sleeves, activated carbon particles are arranged in the sleeves, a mixture of fruit juice and pulp slurry is added into the tank body, then pectinase and amylase are added into the tank body, the pulp slurry after enzymolysis is precipitated to the lower end of the tank body, and the fruit juice is located at the upper end of the tank body. The first motor drive
