Solution of automatic determination of peanut lampblack point
Edible vegetable oil is generally made in two ways: by pressing and by leaching.
Crushing is a method of extracting oil from oil by physical pressing.
Leaching method is a method of extracting oil from oil with edible solvents based on the principle of chemical industry. It is the most advanced production technology recognized internationally at present.
Both the pressed oil and the leached oil must be chemically refined to become edible products.
The oil obtained only by pressing or leaching this first step of the process is called crude oil and is inedible.
In the production process, the pressed oil and the leached oil must be refined through alkali refining, decolorization, deodorization and other chemical processes to remove impurities in the oil, so as to make it meet the national standards and become edible refined oil.
According to the standard GB/T1534-2017 "Peanut Oil", the smoke point of the first-stage leaching products must be greater than or equal to 190 degrees. The detection method of the smoke point in the standard is strictly in accordance with GB/T20795.
Shandong Shengtai Instrument Co., Ltd. Production of ST123B automatic oil smoke point instrument is strictly in accordance with GB/T20795 plant oil smoke point measurement method of the first automatic method to determine.

The apparatus required for the experiment is as follows
1, ST123B automatic grease smoke point instrument
2, smoke point instrument special oil cup
steps
(1) Preparation before the test
1. This instrument is an automatic control instrument. Please read the operation manual carefully before using the instrument.
2, carefully read the People's Republic of China standard GB/T 20795 "determination of smoke point of vegetable oils", understand and familiar with the test method, test procedures and test requirements described in the standard.
3, according to GB/T 20795 "determination of plant fat smoke point" standard requirements, ready for the test of various test instruments, materials, etc.
4, check the working state of the instrument, should conform to the specification of the working environment and working conditions.
5, check the shell of the instrument, must be in a good grounding state, the power line should have a good grounding end.
(2) Open-box inspection of the instrument
1, open the packaging of the instrument, check whether the instrument is damaged.
2. Check the instrument model and accessories according to the packing list.
3, check the accuracy of the instrument before the instrument debugging.
(III) Preparations for machine start-up
1. Put the instrument on the instrument table smoothly, and plug the power cord into the power socket of the instrument.
The power supply should have a good grounding terminal.
3. Clean the test oil cup with edible oil ether.
Second, the experimental process
1. After the power is switched on, the test arm of the instrument is automatically lifted to display the experimental interface.
2. Click "Start", and the test arm falls down to start the test;
Click "Stop" to stop the test and lift the test arm.
3. After the completion of the test, the touch screen will automatically display the value of the smoke point and print the test results. After upgrading, the data can be exported to the computer through the U disk and the original test data can be saved.
