Through the settings of the PLC controller 13, the flow valve 6 and the pH sensor 46, a suitable enzyme liquid preparation is prepared and transported to the primary enzymolysis tank 1. The settings of the first temperature sensor 45 and the first heating block 44 can ensure that the temperature in the primary enzymolysis tank 1 is maintained at the optimal temperature. The cutting component cuts the fruits and vegetables into pieces or slices of appropriate size and transports them to the primary enzymolysis tank 1. The settings of the first servo motor 7, the stirring shaft 8 and the stirring rod 9 are combined to improve the enzymolysis effect. , thereby improving the utilization rate of raw materials and reducing the loss of nutrients. The transmission rod 30 and the gear 29 are driven to rotate by the second servo motor 31. The rotation of the gear 29 can drive the rack 27 and the slider 26 to move in the slide groove 25. The movement of the slider 26 can drive the first cutting blade 28 to move, so that the fruits and vegetables beyond the range of the cutting groove 19 can be cut, avoiding the situation where the fruits and vegetables are over-extruded and damaged when the hydraulic cylinder 22 and the hydraulic movable rod 21 are used to drive the push plate 20 to move. At the same time, the top of the cutting groove 19 can be blocked to ensure the transportation effect of fruits and vegetables. The limiting block 36 is driven to move by pulling the pull rod 38 to make the limiting block 36 detach from the inside of the limiting hole 35. At this time, it can be The mounting frame 33 can be disassembled, and the damaged second cutting blade 34 can be disassembled and replaced through the setting of the bolts and the second cutting blade 34. The fruits and vegetables pushed by the push plate 20 can be cut by the setting of the mounting frame 33 and the second cutting blade 34. The third servo motor 42 drives the third cutting blade 43 to rotate, and then the fruit and vegetable fragments cut by the second cutting blade 34 are cut for a second time to obtain blocks or slices of suitable sizes, thereby improving the enzymolysis effect. Through the setting of the secondary enzymolysis tank 47, the filter screen 52 is used to filter the residual solid impurities in the solution after the primary enzymolysis, and the arc-shaped sealing plate 51 and the filter screen 52 can be disassembled by rotating the bolts to remove the residual solid impurities in the solution after the primary enzymolysis. The impurities on the filter 52 flow into the secondary enzymolysis tank 47 through the primary enzymolysis solution after passing through the filter 52. The temperature and the added enzyme solution are controlled by the processor module 12, so that the residual macromolecular substances in the fruits and vegetables can be further decomposed through the secondary enzymolysis, making the product more delicate and uniform, which is helpful to prepare ultrafine fruit and vegetable powders with smaller particle size and more uniform distribution. The vacuum freeze dryer 59 can provide a vacuum environment. At the same time, in the vacuum environment, the ice crystals are directly sublimated into water vapor and discharged, so as to obtain dry fruit and vegetable powder. The dry fruit and vegetable powder is transported to the ultrafine grinding tank 60, and is crushed again by a plurality of ultrafine grinding blades 63 to obtain the desired freeze-dried ultrafine powder fruits and vegetables.
