Technical Field

[0001] The invention relates to the technical field of deep processing of agricultural and sideline products, in particular to an industrial concentrated kudzu root juice and a preparation method thereof. Background Art

[0002] Pueraria root is the root of wild kudzu or sweet kudzu vine, a plant of the genus Pueraria in the leguminous family. It is a food and medicine agricultural product approved by the Ministry of Health of China. It is known as "Southern kudzu and northern ginseng". Pueraria root is rich in starch, eight essential amino acids, multiple vitamins and trace elements, etc., and has extremely high nutritional value. It is also rich in isoflavones, which have the functions of clearing away heat and detoxifying, promoting body fluid and quenching thirst, nourishing the kidney and spleen, benefiting the stomach and calming the nerves, nourishing and beautifying, delaying aging, clearing the heart and improving eyesight, and sobering up. It has great development prospects. At present, many beverage products have been developed on the market with kudzu root as the main raw material.

[0015] S8: The first concentrated kudzu root juice is concentrated by low temperature vacuum concentration to obtain second concentrated kudzu root juice and kudzu root natural essence, and the kudzu root natural essence is added back into the second concentrated kudzu root juice to obtain concentrated kudzu root juice.

[0016] Preferably, in S1, the fresh kudzu root is placed in a cleaning machine, and the dirt impurities on the surface of the fresh kudzu root are removed by the cleaning machine, and the cleaning time is 20 minutes.

[0017] Preferably, in S2, the weight ratio of Pueraria root to water is 1:1.3-3.6, and the water temperature is set at 45°C-70°C.

[0018] Preferably, in S2, the fresh kudzu root is sent to a crusher for crushing, and the fresh kudzu root is crushed to 90-100 meshes.

[0019] Preferably, the liquefying agent in S3 is an enzyme preparation for liquefaction, generally amylase.

[0020] Preferably, the clarifier in S5 is an enzyme preparation for clarification, generally one or a combination of saccharifying enzyme, pectinase, protease, pectinesterase is selected, the clarification temperature is set at 50°C-66°C, the clarification time is 0.8h-2h, and the pH value is 5.2-6.1.

[0021] Preferably, the filter membrane of the membrane filtration in S6 is a ceramic membrane, a filter cloth, a filter screen or a filter bag, and the pore size of the filter medium is 0.3nm-3nm.

[0022] Preferably, the concentration membrane of the membrane concentration in S7 is an organic membrane, and the membrane pore size is 18 μm-140 μm.

[0023] Compared with the prior art, the invention has the following beneficial effects: the industrial concentrated kudzu root juice and preparation method:

[0024] 1. When preparing concentrated kudzu root juice, fresh kudzu root is put into the cleaning machine, so that the fresh kudzu root can be cleaned by the cleaning machine, and then water and the cleaned fresh kudzu root are added to the crusher, and the cleaned fresh kudzu root is crushed by the crusher to obtain kudzu root pulp. At this time, the baffle plate is moved to the right side by the extension of the first cylinder, so that the kudzu root pulp can be discharged into the separation chamber through the connecting pipe, so that the preliminary separation between the kudzu root residue and the kudzu root liquid can be achieved through the filter plate. At the same time, the extrusion plate is squeezed by the extension of the second cylinder, so that the kudzu root residue and the kudzu root liquid can be separated again, so that the residue of the kudzu root liquid in the kudzu root residue can be reduced as much as possible, thereby avoiding the waste of the kudzu root liquid, and at the same time, it can help to speed up the separation speed between the kudzu root residue and the kudzu root liquid. Since one end of both sides of the filter plate is rotatably connected to the separation chamber through a pin shaft, and the two ends of the third cylinder are respectively rotatably connected to the separation chamber and the other end of the filter plate through a hinge seat, after the discharge hopper is opened, And in the process of extension of the third cylinder, the filter plate can be deflected with the pin shaft as the axis, so that the extruded kudzu root residue can be discharged from the discharge hopper. In this process, the kudzu root pulp is sent to the processing tank, and a liquefier is added to the kudzu root pulp, and the kudzu root pulp is liquefied by the liquefier. The liquefied kudzu root pulp is centrifuged by a centrifuge to obtain kudzu root juice, and a clarifier is added to the kudzu root juice, and the kudzu root juice is clarified by the clarifier. The clarified kudzu root juice is filtered through a membrane to obtain kudzu root clear juice, and the kudzu root clear juice is concentrated through a membrane to obtain a first-level concentrated kudzu root juice. The first-level concentrated kudzu root juice is concentrated by low-temperature vacuum to obtain a second-level concentrated kudzu root juice and kudzu root natural essence, and the kudzu root natural essence is added back to the second-level concentrated kudzu root juice to obtain concentrated kudzu root juice. In this way, through the above operation, multiple separations between kudzu root residue and kudzu root liquid can be achieved when preparing concentrated kudzu root juice, so that the residue of kudzu root liquid in kudzu root residue can be reduced as much as possible, thereby avoiding the waste of kudzu root liquid.

[0025] 2. When crushing the fresh kudzu root, add the fresh kudzu root into the first crushing chamber. At this time, the output end of the driving motor drives the meshing crushing roller to rotate under the action of the gear group, so that the cleaned fresh kudzu root can be crushed by the crushing roller. The fresh kudzu root after the initial crushing falls into the second crushing chamber. At this time, water is added to the second crushing chamber. At the same time, because the worm and a crushing roller are linked through the pulley group, and the worm wheel is meshingly connected with the worm, the worm wheel, the support shaft and the crushing knife rotate together, so that the crushed fresh kudzu root can be crushed by the crushing knife, and then the fresh kudzu root can be crushed by multi-stage crushing, so that the crushing effect and efficiency of the fresh kudzu root are improved, thereby improving the production efficiency of concentrated kudzu juice.
