Description

Technical Field

[0001] The utility model relates to the field of instant foods, in particular to a food heating device and a self-heating tableware for instant brewing type convenience foods. Background Art

[0002] Existing self-heating convenience foods usually use the steam generated by immersing a self-heating pack in normal temperature water for heating, which is usually used for solid-based convenience foods similar to steamed rice and steamed dishes, and cannot effectively heat foods containing more liquid water such as soups and porridges in a short time.

[0003] Currently, instant brewing type convenience foods usually use boiling water or hot water for brewing. This method has the following defects:

[0004] 1. In a cold environment, the heat of boiling water or hot water dissipates quickly. Before the food is fully brewed, the temperature may be too low to restore the taste of the food well.

[0005] 2. For ingredients such as rice noodles that require a long time at high temperature for gelatinization reaction, the energy of hot water alone is not enough to brew the ingredients.

[0006] A better way to solve the above defects is to supplement heat to the brewed food. The main way to supplement heat is to use a self-heating pack. However, there are the following problems with using a self-heating pack for heat supplementation:

[0007] The self-heating pack cannot directly contact hot water because the self-heating pack reacts very quickly when encountering water and is easy to splash hot water and scald people. Therefore, when using a self-heating pack for heat supplementation, normal temperature water needs to be added. This involves preparing water at different water temperatures, and then separating the convenience food packaging into compartments and adding different water temperatures of water separately into the corresponding cavities, which significantly increases the operation complexity, reduces the convenience, and also increases the complexity of the packaging of instant brewing type foods and the generated garbage. In addition, the self-heating pack cannot directly supplement heat to instant brewing type liquid convenience foods, but needs to heat through steam outside the container, and the heating efficiency is too low.

[0008] Based on this, the present application provides a heating device and a self-heating tableware for instant brewing type convenience foods that can directly contact the convenience food to heat or supplement heat to the food, which have the advantages of high heating efficiency, convenient operation, high safety, etc. Summary of the Utility Model

[0009] The utility model aims to solve the technical problems existing in the prior art. For this purpose, the utility model provides a heating device and a self-heating tableware for instant brewing type convenience foods that can directly contact the convenience food to heat or supplement heat to the food, which have the advantages of high heating efficiency, convenient operation, high safety, etc.

[0010] The technical solution adopted by the utility model to solve its technical problems is:

[0011] In a first aspect, a food heating device is provided, comprising a heating base and a water vapor channel arranged on one side of the heating base, wherein: a cavity is provided in the heating base, and a self-heating bag is provided in the cavity; a longitudinal partition is provided in the water vapor channel, a back channel of the longitudinal partition is connected to the cavity, and a front channel thereof is isolated from the cavity, and a first through hole is provided on the front side of the water vapor channel near the bottom, and a second through hole is provided on the top thereof at a position exceeding the longitudinal partition.

[0012] In a preferred embodiment, the cavity is divided into a heating chamber and a water storage chamber by an annular partition, the water storage chamber is arranged at the periphery of the heating chamber, and the annular partition is provided with a third through hole connecting the heating chamber and the water storage chamber, and a water-soluble film is provided at the third through hole.

[0013] In a preferred embodiment, a gel powder bag that converts into a gel state when in contact with water is provided at the second through hole.

[0014] Preferably, the heating base is flat and the water vapor channel is columnar.

[0015] In a second aspect, a self-heating tableware for instant brewing food is provided, comprising a food container and the food heating device arranged in the food container.

[0016] Preferably, the food heating device is integrally formed with the food container, so that the heating base directly serves as the bottom surface of the food container.

[0017] Optionally, the heating base of the food heating device is arranged to fit the bottom surface of the food container, and the water vapor channel is arranged to fit the side wall of the food container.

[0018] Preferably, the edible container is made of a paper material with a waterproof coating or a high temperature resistant food grade plastic material.

[0019] Preferably, the food container is a bowl-shaped, box-shaped or barrel-shaped container.

[0020] Preferably, the inner wall of the food container is also provided with water level scale lines.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] 1. The designed food heating device with a self-heating bag changes the limitation that the existing self-heating bag can only steam solid convenience foods such as rice and vegetables. The steam emitted by the self-heating bag emerges from the water vapor channel in the food heating device, and can heat other foods besides rice and vegetables.

[0023] 2. The self-heating bag is encapsulated in the heating base, and water of any temperature (including hot water) can be directly added to the food container, and there will be no problem of hot water splashing and hurting people;

[0024] 3. The food heating device is directly arranged inside the edible container and directly contacts the self-heating convenient food. Hot water can be added, and the steam generated by the self-heating package inside the food heating device can further heat the hot water, extending the time of the hot water in the high-temperature state, thereby effectively heating instant foods such as rice noodles and porridges, better restoring their taste, and being able to be reliably brewed even in a cold environment.

[0025] 4. The food heating device is in direct contact with the food medium to be heated, and the high-temperature steam directly passes through the food, with high heat exchange efficiency. Therefore, the heating efficiency of water is high, which means that only a smaller heating package is needed to heat the food, effectively saving costs.

[0026] 5. The water-soluble film arranged at the first through-hole can delay the contact time between water and the self-heating package, thereby delaying the reaction time of the self-heating package and ensuring the safety of users.

[0027] 6. The second through-hole for discharging steam is arranged at the lower part of the water-vapor channel, enabling the steam to be discharged from the bottom of the soup, and the steam to fully exchange heat with the soup, with high heating efficiency and not easily scalding users.

[0028] 7. The longitudinal partition in the water-vapor channel can effectively prevent backflow and prevent the solution after the reaction of the self-heating package from contaminating the food when the food heating device or the edible container is tilted. Description of the Drawings

[0043] Embodiment 1

[0044] As shown in the Figure 1 and Figure 2 figures, this embodiment provides a food heating device, which includes a heating base 1 and a water vapor channel 2. The water vapor channel 2 is arranged on one side of the heating base 1. Among them, the heating base 1 is designed to be flat, and its specific shape can be matched according to the shape of the edible container. For example, when the edible container is barrel-shaped or bowl-shaped, the heating base can be designed as a cylindrical shape, an inverted frustum shape or a frustum shape; when the edible container is box-shaped, the heating base is designed as a shape similar to the shape of the box bottom. The water vapor channel 2 is columnar, and its cross-section can be circular or rectangular.

[0045] As shown in the Figure 1 figures, a cavity 1.1 is provided in the heating base 1, and a self-heating pack 3 is provided in the cavity 1.1. A longitudinal partition 2.1 is provided in the water vapor channel 2. The back channel of the longitudinal partition 2.1 is communicated with the cavity 1.1, and its front channel is isolated from the cavity. Moreover, a first through hole 2.2 is provided at the front of the water vapor channel 2 near the bottom, and a second through hole 2.3 is provided at its top at a position exceeding the longitudinal partition 2.1. The second through hole can be provided 2-3 mm above the longitudinal partition for exhausting air when injecting water.

[0046] Working principle: The heating device is placed in the container. During the process of injecting water into the container, water enters the water vapor channel from the first through hole. At this time, air is discharged from the second through hole. As the water level rises, the water overflows the longitudinal partition and enters the heating base until the water level reaches the set water level. At this time, the water submerges above the longitudinal partition and simultaneously submerges the second through hole. At this time, the second through hole is submerged by water, and water no longer continues to enter the heating base. The water that enters the heating base contacts the self-heating pack and undergoes an exothermic reaction to generate a large amount of high-temperature steam. As the steam pressure rises, the high-temperature steam enters the water vapor channel and is discharged from the second through hole to the container together with the water remaining in the water vapor channel to contact the food for heat exchange to achieve heating. If the generated steam pressure is high, the steam will also be discharged from the first through hole.

[0047] Embodiment 2

[0048] Repeat Embodiment 1, the difference is that as shown in the Figure 2 and Figure 3As shown in the figure, in this embodiment, the cavity 1.1 is separated into a heating cavity 1.1.1 and a water storage cavity 1.1.2 by an annular partition 1.2. The water storage cavity 1.1.2 is arranged on the periphery of the heating cavity 1.1.1, and a third through hole 1.2.1 communicating the heating cavity 1.1.1 and the water storage cavity 1.1.2 is provided on the annular partition 1.2. A water-soluble film 1.3 is provided at the third through hole 1.2.1. The water-soluble film is a starch film. The thicker the thickness of the film, the slower the speed at which the film is dissolved, so as to slow down the contact time between water and the self-heating pack.

[0049] In this embodiment, the inner cavity of the heating base is separated into a heating cavity and a water storage cavity by an annular partition, and with the water-soluble film on the annular partition, the water storage cavity can have the function of storing water.

[0050] In this embodiment, water first enters the water storage cavity. The water in the water storage cavity contacts the water-soluble film, causing the water-soluble film to slowly dissolve. At the beginning, due to the relatively thick thickness of the water-soluble film, the speed at which the water-soluble film is dissolved is slower. Thus, the opening time of the third through hole is controlled to control the starting time of heating the self-heating pack, which is usually designed to be dissolved through in 15 - 20 seconds. This design can ensure the safety of users.

[0051] Embodiment Three

[0052] Repeat Embodiment One or Embodiment Two. As shown in the appendix Figure 1 or the appendix Figure 2 As shown in the figure, in this embodiment, a gelling powder pack 4 that turns into a gel state when encountering water is provided at the second through hole 2.3. The content of the gelling powder pack 4 can be carrageenan, sodium alginate, or ice powder used for making jelly snacks.

[0053] In this embodiment, by providing a gelling powder pack at the second through hole, it is in a breathable state under normal conditions and does not affect the exhaust of the second through hole when injecting water into the container. When the water level reaches the set water level (exceeding the position of the second through hole), the gelling powder pack turns into a gel state when encountering water and blocks the second through hole. At this time, it can prevent steam from overflowing from the second through hole, ensuring that all steam is discharged from the first through hole. This design enables the high-temperature steam to act on the bottom of the container, enabling full heat exchange between the steam and the soup, with high heating efficiency and not easily scalding users.

[0054] Application Example One

[0055] As shown in the appendix Figure 4 As shown in the figure, a self-heating tableware for instant food is provided, including an edible container 100 and the food heating device in any one of Embodiments One to Three, and the food heating device is arranged inside the edible container.

[0056] Preferably, the heating base 1 of the food heating device is arranged in close contact with the bottom surface of the edible container 100, and the water vapor channel 2 is arranged in close contact with the side wall of the edible container 100.

[0057] Preferably, the edible container 100 is made of a paper material with a waterproof coating or a high-temperature resistant food-grade plastic material.

[0058] Preferably, the edible container 100 is a bowl-shaped, box-shaped or barrel-shaped container.

[0059] Preferably, a water level scale line (not shown in the figure) is further provided on the inner wall of the edible container 100 to facilitate the control of the injected water level.

[0060] Application Example 2

[0061] The difference from Application Example 1 is only that: the food heating device and the edible container 100 are integrally formed, so that the heating base directly serves as the bottom surface of the edible container. This design can further increase the capacity of the edible container.

[0062] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
