A high-throughput measurement system for waxy corn grain starch viscosity

Abstract

The invention relates to a high-flux measurement system for measuring the viscosity of waxy corn grain starch, wherein each measurement unit comprises a flat bottom cylinder which is used for containing cooked waxy corn grains; a cylinder object is arranged in the center of the interior of each cylinder in a coaxial way, and a circle of slit is reserved between each cylinder and the corresponding cylinder object; the upper end of each cylinder object is connected with a force measurement device; each force measurement device consists of a magnetic coded disc, a rotating shaft, a spring chuck, a magnetoresistor and an ampere meter; each cylinder object is connected with the rotating shaft of the corresponding force measurement device by the corresponding spring chuck; each rotating shaft is connected with a motor; the measurement units are assembled in the same plane in parallel in a form of 10*10 matrix. According to the high-flux measurement system, the viscosity of the grain starch of the cooked fresh-eating waxy corn is measured by a rotating cylinder method, so that the system is rapid and standard in measurement and high in flux; furthermore, the viscosity values of 100 parts of materials can be measured and recorded at the same time, so that the combination of accuracy, high speed and high flux can be realized in the real sense.

Description

technical field [0001] The invention relates to the field of waxy corn starch viscosity, in particular to a high-throughput measurement system for waxy corn grain starch viscosity. Background technique [0002] In the prior art, in the process of cultivating new varieties of fresh waxy corn, the viscosity of the starch after the grains are cooked is an important indicator. The rapid viscosity analyzer (RVA instrument) can accurately and systematically measure the viscosity properties of starch, but this method has high requirements for starch samples, and the measurement time of a single sample is long (about 20 minutes), which is not suitable for large-scale breeding in the breeding process. Batch determination. Another commonly used method is to rely on actual tasting by scientific researchers, but the human factor is high, the experimental error is large, and the test data made by different scientific researchers lack horizontal comparison, which hinders the process of b...
