Abstract

The invention relates to a device for testing heat and gas released by a self-heating food heating bag. The device comprises a heat measuring mechanism and a gas collecting mechanism. The heat measuring mechanism comprises a heat measuring container, a reaction bottle and a quantitative funnel; a sample to be measured is placed in the reaction bottle, a heat measuring assembly for measuring the heat generated by the reaction bottle is further arranged in the heat measuring container, the quantitative funnel is filled with water and is arranged above the reaction bottle, and a liquid outlet ofthe quantitative funnel is further connected with the reaction bottle. The gas collecting mechanism comprises a gas guide pipe, a water tank, a fixing support and a gas collecting bottle, the fixing support is installed at the bottom of the water tank, one end of the gas guide pipe is connected with the reaction bottle, an exhaust assembly is installed at the other end of the gas guide pipe, the gas collecting bottle is filled with water, and during measurement, the gas collecting bottle is in butt joint with the exhaust assembly in an inverted state and used for collecting gas generated by reaction in the reaction bottle. Compared with the prior art, the device has the advantages that the amount of heat and gas released by the self-heating food heating bag can be measured at the same time, technical support is provided for evaluating the quality and safety of the heating bag, and the technical blank in the field is filled up.

Description

technical field

[0001] The invention belongs to the technical field of testing devices, and relates to a testing device for the amount of heat and gas released from a heating bag of self-heating food. Background technique

[0002] As a new type of popular fast food, self-heating food has the advantages of fast heating speed and convenient eating, so it is sought after by many consumers and businesses. Combined with the innovation of taste and shape, self-heating food has become a kind of instant fast food that people love.

[0003] According to surveys and data inquiries, self-heating food is composed of ingredients and heating packs. The main components of self-heating food heating packs on the market currently include aluminum powder, calcium oxide, iron powder, magnesium powder, etc., which will release a large amount of heat and a hydrogen-based gas. Its heat release and continuous heat release time are important indicators for evaluating the quality of heating packs. I...

Examples

Embodiment 1

[0047] This embodiment provides a test device for the amount of heat and gas released from the heating package of self-heating food, and its structure is as follows: Figure 1-Figure 3 shown, including:

[0048] (1) Reaction bottle 4: a container for the reaction between the heating pack sample (i.e. the sample 2 to be tested) and water, equipped with a sealed bottle cap, which has good sealing and heat conduction functions, and is placed in the heat insulating cavity surrounded by the heat insulating foam 3 Inside, the whole reaction bottle 4 is completely submerged by water during operation.

[0049] (2) Calorimetric container 1: a cylindrical container lined with thermal insulation foam 3, which has a good thermal insulation effect and is used to hold water. The heat release of the heating package is calculated by measuring the change of water temperature.

[0050] (3) Thermal insulation foam 3: lined in the calorimetric container 1, with a sealed design with a cover.
