Method for automatically heating pop-top can

Abstract

The invention discloses a method for automatically heating a pop-top can. A heating can with a turnup is arranged from the bottom of an outer can; three combined granules A, B and C are filled in the upper part in the heating can; a water cup is arranged at the bottom of the heating can; a sealed thin-film layer seal is formed on the top of the water cup; the water cup is filled with mixed liquor; a piston guide pipe is arranged in the water cup; a piston is arranged in the piston guide pipe; the head of the piston is provided with a tip; the tip is contacted with the sealed thin-film layer; a groove is formed in the piston; a sealing ring is arranged in the groove; the sealing ring is in sealing fit with the inner wall of the piston guide pipe; a bottom cover is arranged below the turnup of the heating can; a button is arranged in the middle of the bottom cover and is contacted with the bottom of the piston; the inner turnup of the bottom cover, the heating can and the outer turnup of the outer can are rolled and sealed; the drink is filled from an upper port of the outer can; and a can cover is sealed.

Description

technical field [0001] The invention relates to an automatic heating method for pop cans, belonging to the field of beverages and foods. Background technique [0002] Automatic heating of drinks can meet people's needs for convenience of warm drinks when working in the field and traveling. In the existing technology, the principle of hydration and heat release of calcium oxide and other substances is generally used to make an independent heat generating unit, and the heat generating unit is installed in the beverage tank. heating. This type of existing technology still has the following disadvantages: 1. When the ambient temperature is low, the hydration rate of calcium oxide is slow, and the heating time in the early stage is too long; 2. When the temperature of the heat generating unit rises to 50°C, the hydration reaction of calcium oxide is fast Enhanced, causing the water temperature of the heat generating unit to rise instantaneously, and the steam pressure is too hi...

Problems solved by technology

This type of existing technology still has the following disadvantages: 1. When the ambient temperature is low, the hydration rate of calcium oxide is slow, and the heating time in the early stage is too long; 2. When the temperature of the heat generating unit rises to 50°C, the hydration reaction of calcium oxide is fast Enhanced, causing the water temperature of the heat generating unit to rise instantaneously, the steam pressure is too high, and it is easy to cause safety problems such as tank explosion; 3. The residue of the heat generating unit is highly alkaline, which is easy to pollute the environment
