A separation tank for measuring crude fat content and a device for measuring crude fat content

Abstract

The invention relates to a separation tank used for crude fat content measurement, and a crude fat content measurement apparatus, and belongs to the technical field of fat content test. The separation tank used for crude fat content measurement comprises a tank body used for containing an immersion liquid and accommodating a corresponding separation cylinder, an immersion supporting structure arranged in the tank body and used for supporting the separation cylinder to make the separation cylinder be partially or completely immersed in the immersion liquid, and a centrifuge supporting structure used for supporting the separation cylinder to make the separation cylinder be completely disengaged from the immersion liquid and being in rotary fit with the separation cylinder. The separation tank used for crude fat content measurement can realize immersion and centrifuge of samples in the separation cylinder in the same tank body, is convenient for repeating immersion and centrifuge, greatly improves the dissolution efficiency of fats in the immersion liquid, and is especially suitable for measuring a large amount of samples.

Description

technical field [0001] The invention relates to a separation tank for measuring crude fat content and a crude fat content measuring device, belonging to the technical field of fat content testing. Background technique [0002] At present, the device for measuring the crude fat content in feed and food is a Soxhlet extractor. Using this device to determine the crude fat content is not only time-consuming and requires a large amount of solvent, but also requires a special Soxhlet extractor and a special constant temperature water bath. The water pipe must be connected for condensation, otherwise there is a risk of ether leakage or explosion. The number of samples measured at the same time using the Soxhlet extractor is small. At the same time, the Soxhlet extractor is assembled from multiple parts, and the connecting parts are connected by grinding. Extra care must be taken during operation. Crushed, when using the Soxhlet extractor, special care is required, and the requirem...

Problems solved by technology

[0004] When using a Soxhlet extractor for the determination of crude fat content, the sample is wrapped by a filter paper bag and placed in the extractor, the solvent dissolved in crude fat will stay in the filter paper bag and the gap between the sample particles, and it is difficult to diffuse into the outside of the filter paper bag In this way, even if fresh solvent is continuously added to the extractor, the soaking liquid with a high concentration of fat in the filter paper bag is difficult to diffuse into the solvent

However, the soaking solution with high fat concentration in the filter paper bag and in the gap between the sample particles also hinders the continuous dissolution of the crude fat in the sample, resulting in low fat extraction efficiency.
