Gel strength measuring method and device

Abstract

The invention relates to a gel strength measuring method and device. The method is characterized by including the steps: 1) preparing the measuring device and gel solution with the weight percentage content of 1.5%; 2) placing the gel solution on a gravity sensing platform of the measuring device; 3) making zero for weight data of the measuring device by a data reset key of a keyboard of the measuring device; 4) adjusting a tightening adjustment screw of the measuring device, enabling a detecting head to pressure on the surface of gel to be detected, and driving the detecting head to apply pressure to the surface of the gel by a spiral expansion joint; 5) acquiring information of the surface of the gel bearing the pressure by the aid of a gravity sensor of the bottom surface of the gravity sensing platform, converting the information by an A / D (analog to digital) conversion module of the measuring device, transmitting the converted information to a control processing unit, and processing the information; 6) locking maximum pressure born by the surface of the gel before being broken and duration time bearing the maximum pressure by the control processing unit when the gel is broken by gravity. The measuring method has the advantages that the measuring device is simple in structure, high in accuracy and efficiency, short in measuring time and the like.

Description

technical field [0001] The invention relates to a method and device for measuring gel strength, which is particularly suitable for measuring the strength of gels such as agar and carrageenan. The invention belongs to the technical field of chemical product testing equipment. Background technique [0002] At present, food additives such as agar and carrageenan are widely used in technical fields such as food, medicine, biology, and chemical industry, and the demand at home and abroad is very large. Since gel strength is an important indicator of gels such as agar and carrageenan, it is necessary to test the strength of gels such as agar and carrageenan. [0003] In the prior art, to detect the strength of gels such as agar and carrageenan, there are mainly constant pressure rupture method, hydraulic method, physical property tester Pheo Meter method, etc. [0004] Fracture method: use 10 hammer series with increasing weights to fall at the same time, and press them on 10 st...
