Examples
example 1
[0021] Example 1: A high-efficiency food heating pack, consisting of a non-woven bag and a heating composition; the heating composition is prepared by mixing the following materials in a weight ratio: 20 parts of aluminum powder, 45 parts of calcium hydroxide, silicon 5 parts of algae earth, 20 parts of silicon dioxide, 10 parts of sodium fluoride powder.
[0022] The materials are all in powder form. Put the mixed exothermic composition into a non-woven bag and place it in a Dewar bottle, add water twice the mass of the total mixture, and start to steam in 35 seconds, and reach the peak within 4 minutes. 97°C (boiling point temperature), which can last for several minutes, generates a large amount of steam, and the temperature rises to 95°C in 20 minutes, and the temperature can remain at 90°C for 30 minutes.
example 2
[0023] Example 2: A high-efficiency food heating pack, consisting of a non-woven bag and a heating composition; the heating composition is formulated according to the weight ratio of the following materials: 15 parts of aluminum powder, 50 parts of calcium hydroxide, diatom 5 parts of soil, 15 parts of silicon dioxide, 15 parts of sodium fluoride powder.
[0024] Stir the mixed powder evenly and put it into a non-woven bag. Put the packaged heating pack in a Dewar bottle and add water twice the mass of the total mixture. Steam will start to emerge in 25 seconds and reach 95 in 3 minutes. °C, it can last for several minutes, a large amount of steam is generated, and the temperature is not lower than 90 °C in 20 minutes.
example 3
[0025] Example 3: A high-efficiency food heating pack, consisting of a non-woven bag and a heating composition; the heating composition is formulated according to the weight ratio of the following materials: 30 parts of aluminum powder, 50 parts of calcium hydroxide, diatom 4 parts of soil, 13 parts of silicon dioxide, 3 parts of sodium fluoride powder.
[0026] Stir the mixed powder evenly and put it into a non-woven bag. Put the packaged heating pack in the Dewar bottle and add water twice the mass of the total mixture. Steam will start to emerge in 50 seconds, and it will reach the peak in 2 minutes and 30 seconds. At 97°C, it can last for several minutes, and a large amount of steam is generated, and the temperature is not lower than 91°C in 20 minutes.
