Overview
QW-SZF-062/02 crude fat measuring instrument is a device designed by introducing new technology for fat measurement, which has the characteristics of reasonable design, stable performance, high Accuracy, time-saving and labor-saving operation. The instrument measures the fat content according to the principle of Soxhlet extraction and weight determination, dissolves the fat through organic solvents, and then calculates the results through extraction, separation, drying and weighing. Its various indicators and performance meet the requirements of imported congeneric products. It is a reliable equipment for fat determination in food, fat, feed and other industries. The instrument is mainly composed of three parts: heating, extraction and chilling down. The heating temperature can be adjusted according to the boiling point of the Reagent and the Ambient Temperature, and the sample can be repeatedly soaked and rinsed to achieve the purpose of rapid determination.

10. Digital automatic temperature control, can be adjusted in real time according to the boiling point of the solvent and the indoor temperature.
11. Glass grinding port is used at the connection of the extraction bottle, and the sealing performance is good.
12. Six samples can be determined simultaneously.
Principle
This instrument is based on the Soxhlet extraction principle and weight determination method to determine the fat content. Its Working Principle is to dissolve the fat under organic solvent, separate the fat from the solvent by extraction method, and then dry and weigh to calculate the fat content. Specifically, after the sample is extracted with a solvent such as petroleum ether/anhydrous ether or petroleum ether, the material obtained by evaporating the solvent is crude fat. Because in addition to fat, it also contains pigments, volatile oils, waxes, Resin and other substances, the extraction method measures free fat. The instrument is mainly extracted by digital electric heating and constant temperature water bath to realize immersion and rinsing and semi-automatic solvent recovery.
Applications
Food, fat, feed, oil and various fat products industries
Standards
In line with national standards
Steps
1. According to the Reagent Boiling Point and Ambient Temperature, adjust the heating temperature through the digital temperature control meter.
2. Place the sample in the extraction device.
3. Add organic solvents (such as petroleum ether/anhydrous ether).
4. Start the instrument, carry out the heating and extraction process, and repeatedly soak and rinse the sample.
5. Steam off the solvent.
6. Dry the separated fat.
7. Weigh the fat weight after drying.
8. Calculate the fat content in the sample based on weight.
Notice
Please read the instructions carefully before operation to ensure that you understand the principle and operation steps of the instrument.
* Set the heating temperature reasonably according to the boiling point of the solvent used and the Ambient Temperature in the laboratory.
* The connection of the extraction bottle is a Glass grinding mouth, and it is necessary to ensure that the connection is tight during installation to ensure good sealing performance.
* When using organic solvents (such as petroleum ether, ether), it should be operated in a well-ventilated environment and pay attention to fire and explosion protection.
* The heating power of the instrument is 1000W, and the standard power supply AC 220V 50HZ is used. Please ensure stable power supply.
The instrument is a water bath heating method, please ensure that the heating medium is sufficient.
* Six samples can be measured simultaneously, please do not use in excess.
* After the measurement is completed, please follow the specifications for solvent recovery and instrument cleaning.
* The instrument weight is 28Kg, so pay attention to safety when moving and placing.
This instrument measures samples with an oil content of 0.5% to 60%. Exceeding this range may affect the accuracy of the measurement.
