Multi-layer self-heating food heating bag and preparation method

Abstract

The invention relates to a multi-layer self-heating food heating bag which comprises an interlayer type thin film, a heating agent A, a heating agent B, a heat conducting agent A, a heat conducting agent B, an aromatic and a hydrophilic agent; the interlayer type thin film is composed of five thin film bodies which are mutually nested and independently sealed, the five thin film layers are respectively a first thin film, a second thin film, a third thin film, a fourth thin film and a fifth thin film from inside to outside, and a first interlayer, a second interlayer, a third interlayer and a fourth interlayer are respectively formed by filler substances between every two adjacent layers of films in a space between the adjacent thin films, the first thin film is filled with a heat conducting agent A, the first interlayer is filled with a heat generating agent A and a heat conducting agent B, the second interlayer is filled with the heat conducting agent B and a hydrophilic agent, the third interlayer is filled with a heat generating agent B and the heat conducting agent A, and the fourth interlayer is filled with the heat conducting agent B, an aromatic agent and a hydrophilic agent.

Description

technical field [0001] The invention belongs to the field of fast-moving self-heating foods, and in particular relates to a multi-layer self-heating food heating pack suitable for self-heating foods such as starch, protein and dietary fiber and a preparation method thereof. Background technique [0002] With the rapid development of the economy, the pace of life of the masses continues to accelerate, and fast-moving food has gradually entered the field of vision of fast-paced consumers. The proportion of products in the market is increasing day by day, and its economic upside is huge, and the types of self-heating food are also increasing, such as: self-heating hot pot, self-heating rice, self-heating snail noodles, etc. [0003] At present, most of the self-heating foods on the market can reach a maximum temperature of 70°C, and the duration of high temperature is a major reason affecting their sales. In response to this problem, experts in various fields have also proposed...

Problems solved by technology

[0007] The purpose of the present invention is to solve the problems that the existing self-heating food heating package produces a large amount of lime gas when injecting water to release heat, the heating duration is short, and it is easy to gather into blocks, resulting in insufficient internal heat release. It provides a rapid and continuous heat release Multi-layer self-heating food heating pack with long time, not easy to gather into lumps, and aromatic smell
