Semi-automatic grease smoke point meter/grease smoke point meter BLD-1 is an instrument used to determine the smoke point of vegetable grease. This instrument is simple and is widely used in grease processing, grease storage and transportation, etc.
1. Introduction
Microcomputer temperature control instrument display window, the upper display for the temperature display window, the lower display for the set value display window. The green indicator light is the heating working state. The orange indicator is a digital lock indicator. Touch the key: set, lock, shift, "", "-" five keys.
2. Installation method
Carefully load the oil or melted fat sample into the measuring cup so that the liquid level is just on the loading line, adjust the position of the electric furnace and the measuring cup so that the spotlight beam passes through the center of the measuring cup, and vertically clamp and hang the thermometer and rod sensor on both sides of the center of the cup, about 6mm from the bottom of the cup, and keep them parallel.
The main reason for the low smoke point of oil is that a small amount of phospholipids are eaten during the hydration of soybean oil. When the oil is heated at 280 ℃, the color of the oil becomes dark and the trace precipitates. After deodorization, the phospholipids are still contained in the oil, and the phospholipids are oxidized and decomposed at high temperature to turn black and bitter.
