Abstract

The invention discloses an oil melting point measurer which can achieve a high-accuracy detection result. The oil melting point measurer comprises a base, wherein a measurement substrate is arranged on the base; a PLC (programmable logic controller) is arranged in the measurement substrate; a display connected with the PLC is arranged on the measurement substrate; a sample clamping arm controlled by the PLC to move is arranged on the base; a refrigeration tank and a refrigeration module controlled by the PLC are arranged on the measurement substrate; a first temperature sensor is arranged in the refrigeration tank; a heating tank is arranged on the measurement substrate; a heating device controlled by the PLC and an air turbulent flow pipeline connected with an air compressor which is controlled by the PLC are arranged on the heating tank measurement substrate; a refrigeration timing device connected with the PLC is arranged on the measurement substrate; a second temperature sensor connected with the PLC is arranged in the heating tank; a first infrared detector which is connected with the PLC and is used for detecting whether a sample is inserted in place is arranged in the heating tank; an infrared sensor which is connected with the PLC and is used for detecting the infrared transmittance of the oil column is arranged on the measurement substrate at the position corresponding to a sample oil column.

Description

technical field [0001] The invention relates to an instrument for measuring the melting point of oil. Background technique [0002] The detection of the melting point of fats and oils should adopt the method specified in GB / T24892-2010 / ISO 6321:2002: under the specified conditions, prepare a solidified fat column at one end of the capillary, immerse it in a water bath of a certain depth, press the The temperature at which the fat column slides upward at a predetermined rate of temperature rise is recorded as the melting point of the fat. However, if the method of manual testing is used to measure according to the standard, not only the operation is cumbersome, but also it is difficult to accurately record the melting point value, and the measurement accuracy and stability are poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an instrument for measuring the melting point of fats and oils with high accuracy of...
