Method and device for measuring gel strength

Abstract

The invention relates to a method and device for measuring gel strength, which are characterized in that: 1) preparing a measuring device and a gel solution with a mass percent content of 1.5%; 2) placing the gel under the gravity of the measuring device on the sensing platform; 3) use the data reset key of the keyboard of the measuring device to reset the weight data of the measuring device to zero; 4) adjust the ratchet tightening screw of the measuring device so that the detection head is pressed on the surface of the gel to be tested, and the screw The stretcher drives the detection head to apply pressure to the gel surface; 5) Use the gravity sensor on the bottom surface of the gravity sensor platform to collect the pressure information on the gel surface, and send the information to Controlling the processing unit for processing; 6) When the gel is broken by gravity, the control processing unit locks the maximum pressure on the surface of the gel before it is broken and the duration of the maximum pressure. The invention has the characteristics and beneficial effects of simple structure of detection equipment, high precision, short measurement time and high efficiency.

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...
