YUS-AZ automatic oil acid analyzer, vegetable oil acid value / animal fat tester - Zhengzhou Grain Machinery Factory
Model YUS-AZ
One: Product Introduction
The acid value is expressed in a form containing the amount of free acid in organic compounds. The acid value of oil is required for a free fatty acid and potassium hydroxide in mg number one gram of fat. It is not only a quality index of oil and fat, but also a food hygienic indicator of edible oil. The acid value of fresh or refined oils are low, due to improper storage or processing, will cause the increase of acid value. Therefore, only strengthen the determination of the acid value of oil, in order to understand the quality of products.
继开发 YUS — 3 加强型酸价快速测定仪（半自动）之后，又成功地研制了全自动酸测定仪。 The instrument overcomes the defect that the end point of titration is judged by the naked eye, and the overall renewal design is made from the circuit to the electrochemical analysis operation. The digital display device uses high luminance counter, which not only facilitates observation, but also improves counting precision. The "electronic indicator" is used to determine the end point, so that the whole process of titration can be detected by the instrument, and the titration jump point can be observed accurately, and the complete titration curve can be plotting. We have also successfully miniaturized the sensing and reference electrodes and carefully compounded the electrode with the electrode to make the test more convenient and simple. After repeated experiments, we improved the electrolyte formula to make it more excellent. Even in low temperature in winter, it can quickly dissolve oil and ensure the accuracy of measurement. Because this instrument does not use chemical indicator to judge the end point, it can show its superiority in the determination of dark fat. It can provide an objective way to determine the end point accurately, and do not need to prepare and calibrate standard alkali solution. It does not need to be determined by the national standard method, and it can show its superiority in the determination of dark oil. It can provide an objective way to determine the end point accurately, and do not need to prepare and calibrate standard alkali solution. It does not need to be determined by the national standard method, and it can show its superiority in the determination of dark oil. It can provide accurate objective judgement of end point means, without the preparation and calibration of standard alkali solution, not the standard method using a large amount of ether as solvent, so the instrument has good repeatability, no toxicity, cost saving, simple operation, easy to master and can be used for the advantages of flow detection, directly display the results in a few minutes.
This instrument is mainly used for all kinds of vegetable oil and animal oil acid value determination, the special debugging can be used to determine rice, wheat flour, milk, wine, soy sauce, acidity or total acidity. This instrument can be widely used in such sectors as grain, oil, food, fermentation, light industry, sanitary and epidemic prevention inspection, and other sectors, such as scientific research and teaching.
Two: working principle
The instruments can be widely used in such sectors as grain, oil, food, fermentation, light industry, health and epidemic prevention inspection, and other sectors, such as scientific research and teaching. M + free fatty acid reaction + CI + H2O + e- = MCl+1/2 + H2 OH- electrogeneration alkali contained immediately with the bottom liquid oil samples: M- + RCOOH = RCOO-+H2O and once completed, a sense of potential signal sensing element will make the instrument automatically stop titration, neutralization of free fatty acid alkali consumption equivalent power to form acid value directly read on screen display.
