Detection device for preservative content in powder food

Abstract

The invention discloses a detection instrument for the content of preservatives in powdered food, which comprises an inner tube of the detection instrument, an outer wall of the detection instrument, and a sealing cover. The top of the test instrument is provided with the sealing cover, wherein, the upper part of one side of the inner tube of the detection instrument is provided with a feed port, and the feed port penetrates the outer wall of the test instrument and extends to the side of the outer wall of the test instrument, The lower part of the other side of the inner tube of the detection instrument is provided with a discharge port, and the discharge port penetrates through the lower part of the other side of the outer wall of the detection device and extends to the side of the outer wall of the detection device. A motor 1 is arranged inside, and the bottom of the motor 1 is provided with a partition, and the bottom of the partition is provided with an air rod. Beneficial effects: the balance of stirring and the uniformity of heat are improved, the accuracy of detection is increased, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of food detection, in particular to a detection instrument for the content of preservatives in powdered food. Background technique [0002] At present, when the content of preservatives in food is detected, it is mainly carried out in test tubes. The general method is to put the sample to be tested into the test tube. During the chemical reaction between the reagent and the test sample, in some tests, it is necessary to Stir and heat to ensure that the chemical reaction is fully carried out, so as to obtain the prepared test results. Existing food preservative testing instruments often require manual stirring and do not have a special heating structure. When heating with an external heat source, there is a problem of uneven heating. This results in poor detection accuracy. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention ...
