Problems solved by technology

[0003] Fruits and other agricultural products often encounter the following problems when performing juice centrifugation testing. For example, after cutting fruits such as apples and pears, the juice contains easily oxidized components, which will cause browning due to contact with the atmosphere after cutting. The problem of juice detection error is caused, and the second is that suspended substances in the environment after cutting are easy to attach to the cut surface in the air flow disturbance, and then placed in the test tube in the subsequent juice extrusion operation, causing poor purity of the juice after centrifugation , the resulting detection error problem

Abstract

The invention provides centrifugal sample separation equipment for agricultural product detection, and a centrifugal sample separation method thereof, and relates to the field of centrifugal detection equipment. The centrifugal sample separation equipment comprises a machine body and a box body, the box body is fixedly connected to the top end of the machine body, and a centrifugal frame is arranged in the box body; the centrifugal frame comprises lantern rings, a bearing sleeve, an internal thread sleeve, a shaft rod and connecting handles, the shaft rod is fixedly connected to a driving shaft extending out of the machine body, the connecting handles are symmetrically fixed to the side wall of the shaft rod, and the other ends of the connecting handles are fixedly connected with the internal thread sleeve; the bearing sleeve is arranged above the shaft rod, and the top end of the shaft rod is sleeved with the bearing sleeve; the lantern rings are symmetrically fixed on the side wall of the bearing sleeve; and a material processing device is arranged at the centrifugal frame and comprises a pumping and discharging pipe, a squeezing assembly, a juicing cup and a collecting assembly. The processing mode can effectively avoid the problems that after fruits in the atmospheric environment are sectioned, due to rapid oxidation, the juice property changes, and impurities are mixed into the juice.

Description

technical field [0001] The invention relates to the field of centrifugal detection equipment, in particular to a centrifugal sample separation device and a centrifugal sample separation method for agricultural product detection. Background technique [0002] Centrifugal detection equipment is an instrument that uses the centrifugal force generated by the rotating rotor to separate substances of different densities and particle sizes in suspensions or emulsions, or to analyze them while separating. It has a wide range of applications and is suitable for chemical, Food, pharmaceutical, environmental protection, mining, teaching and other laboratories. [0003] Fruits and other agricultural products often encounter the following problems when performing juice centrifugation testing. For example, after cutting fruits such as apples and pears, the juice contains easily oxidized components, which will cause browning due to contact with the atmosphere after cutting. The problem of...
