Embodiment 1

[0050] This embodiment provides a sample loading device for calorific value detection (see the schematic diagram in figure 1 ), including the sample cup 1 and the ignition wire 2 directly above the sample cup 1;

[0051] The bottom of the sample cup 1 is not provided with a fixed cup bottom, and a bottom plate 3 is movably connected to the bottom of the sample cup 1, and the bottom plate 3 is used as the movable cup bottom of the sample cup 1;

[0052] One end of a bottom plate limiting device 4 is connected to the free end of the bottom plate 3, and the other end of the bottom plate limiting device 4 is suspended on the ignition wire 2, so that the bottom plate 3 is fastened to the sample cup 1 bottom.

[0053]This embodiment further provides a calorific value detection device, comprising a reaction cartridge and the above-mentioned calorific value detection sample loading device vertically higher than the bottom of the reaction cartridge, and the opening at the bottom of th...

Embodiment 2

[0055] This embodiment provides a detection method for a food self-heating package, which detects exothermic agent samples from F1 to F10 derived from the food self-heating package.

[0056] 1. Detecting the calorific value of the food self-heating package specifically includes the following steps:

[0057] (1) exothermic agent is placed in described sample cup, water is placed in described reaction cartridge;

[0058] (2) After the thermal balance of the calorific value detection device is stabilized, energize and fuse the ignition wire, so that the exothermic agent falls into the water, and the calorific value detection device performs the measurement synchronously; during the measurement process, in the reaction cartridge Filled with a small amount of nitrogen;

[0059] (3) After the temperature of the oxygen bomb system is constant, the measurement is completed, and the calorific value q is recorded. The results are shown in Table 1 below.

Abstract

The invention relates to the field of material detection, in particular to a calorific value detection sample loading device and a food self-heating package detection method. The calorific value of the material is accurately detected. At the same time, the present invention optimizes and improves the detection method of applying the above-mentioned calorific value detection device to food self-heating packs, and breaks through the current bottleneck of lack of special detection methods for food self-heating packs, subjectivity in thermal efficiency evaluation, and difficulty in meeting industrial needs. It can provide special devices, scientific methods and technical support for quality evaluation for the safe production and use of self-heating food heating packs.

Description

technical field [0001] The invention relates to the field of material detection, in particular to a calorific value detection sample loading device and a food self-heating package detection method. Background technique [0002] With the continuous improvement of consumption levels and the acceleration of the pace of life, today's self-heating food has derived many categories such as self-heating rice, self-heating hot pot, self-heating vermicelli, self-heating noodles, self-heating snail noodles, and self-heating vegetables. . As one of the necessary components of self-heating food, heating pack plays a particularly important role in the development of self-heating food. [0003] However, when there is a problem with the quality of the heating pack, it will affect the reheating effect of self-heating food at light level, and it will bring certain safety risks in severe cases. Therefore, it is urgent to develop a comprehensive detection method for heating packs. In this reg...
