Crude fat measuring instrument with enhanced cooling function

Abstract

The invention discloses a crude fat measuring instrument with an enhanced cooling function. The crude fat measuring instrument comprises a containing box, a plurality of measuring pipe assemblies, a water outlet main pipe and a water inlet main pipe, wherein the plurality of measuring pipe assemblies are arranged in the containing box in parallel, the water outlet main pipe is connected to a drainage water pipe, and the water inlet main pipe is connected to a tap water pipe; each measuring tube assembly comprises three parts, namely an electric heating water bath part, an extraction part and acondensation part; each electric heating water bath part comprises a water container and a heating pipe, wherein the heating pipe is arranged in the water container; each extraction part comprises asolvent bottle, a sample containing bottle and an evaporation pipe, wherein the solvent bottle is arranged in the corresponding water container in an inserted mode, the sample containing bottle is arranged in the solvent bottle in an inserted mode, and the evaporation pipe is arranged above the sample containing bottle; the solvent bottles are communicated with the sample containing bottles; eachcondensation part comprises an upper condensation pipe, a lower collection pipe and a partition plate, wherein the partition plate is arranged between the collection pipe and the condensation pipe; and the evaporation pipes are arranged inside the condensation pipes. According to the crude fat measuring instrument, cooling water of each condensation pipe flows independently, so that the cooling effect is greatly improved, the condensation efficiency of the condensation pipes is improved, and therefore the measuring speed of the measuring instrument is increased.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a crude fat measuring instrument with enhanced cooling. Background technique [0002] Soxhlet extraction is a common method for determining the crude fat content of biological samples. Its principle is: according to the principle of Soxhlet extraction, the crude fat content of the sample is obtained by heating and extracting the sample with a solvent. During the extraction, it is heated by an electric hot water bath, and the temperature of the water bath is adjusted according to the boiling point of the solvent. The evaporated solvent with the sample is cooled and recovered through the condenser at the upper end. In this way, the sample is soaked and washed repeatedly during the extraction process, so as to achieve rapid The purpose of determining crude fat. Defects in the design and use of the existing crude fat analyzer: 1. One rubber tube controls two condensation...

AI Technical Summary

Problems solved by technology

Defects in the design and use of the existing crude fat analyzer: 1. One rubber tube controls two condensation pipes, that is, the condensed water flows out from the first condensation pipe and then enters the second condensation pipe, and the cooling water is repeatedly cooled, resulting in the second condensation pipe. The condensation effect of the tube is poor, the extraction frequency of the second extraction bottle is low in the same time period, the result error between the two parallel samples is large, and the repeatability is poor; 2. The area containing the sample solvent in contact with the condensation tube is not enough Large, poor cooling effect, resulting in a long time to complete sample extraction in the process of using the crude fat analyzer, affecting production efficiency
