The invention relates to a method for treating a food which is in an insulating encapsulation or casing or which will be introduced into same, by means of non-conventional ohmic heating. The heating serves, in particular, to treat sausage products in an intestine, such as Brhwurst (scalded sausage), hot dogs or similar food products. The food is brought into contact with spaced electrically conductive electrodes, wherein the electrodes are connected to a controllable power source. According to the invention, the electrodes are each in the form of at least one first and one second electrode group, wherein the electrode groups are at a distance A.sub.EG to one another. Each electrode group has a number of individual electrodes, similar to a comb-like set of needles, wherein the neighbouring individual electrodes of the comb-type set of needles are each at a distance A.sub.EE to one another. The distance A.sub.EG is greater than or max. equal to the distance A.sub.EE. The respective comb-like set of needles penetrates the insulating encapsulation or the casing of the food, wherein a penetration process is carried out in such a way that entry and exit points of the comb-like set of needles are formed in relation to the food and the encapsulation or casing.

Apparatus for warming cloths in a portable box. The warming box includes a heater assembly with slots configured to receive multiple packages of cloths. The slots are defined by panels that have embedded heaters. Heaters are also positioned at the bottom of the slots. Two temperature switches control the heaters in order to maintain the temperature of the packages with specified limits. One temperature switch is positioned above the slots on an inside surface of the lid. The other switch is located at the bottom of one of the slots. The lid also includes a tilt switch that de-energizes the heaters when the lid is opened. The warming box has feet configured to mate with corresponding recesses in the lid, thereby making the boxes stackable, such as when used with a docking station. The docking station has a wiring harness that provides power to each warming box.

The invention relates to a lunchbox for storing, transporting and heating food, in particular food prepared for consumption. This should be easy to handle.

The lunchbox comprises an upper shell (1) and a lower shell (2) which connected to one another in a hinged manner on one longitudinal side, wherein a closure is provided on the opposite longitudinal side. A shell having a circumferential and L-shaped angled edge region is arranged in the lower shell (2), which is assigned a thermal insulation and a heating element, wherein a groove for receiving a seal is formed in the circumferential edge region of the shell.

Packaging devices such as bags, pouches, envelops, containers, and the like, can include an integrated heating system. The packaging devices described herein have multiple potential uses such as for the containment and heating of single-serving meals, drinks, massage oils, masks, body wax, anti-wrinkle eye creams, and the like, to be heated on the go. The packaging devices described herein can also be used for instant heating of food and/or beverages for backcountry use. In some embodiments, the packaging devices use fibrous natural materials (e.g., leaf skeletons and soft biomaterials like chitosan) along with silver nanowires to create completely biodegradable, and reusable self-heating packaging.

A sustainable solar energy carrier that generates heat without emissioning any gas such as GHGs and can be recycled and recharged by solar energy. The energy carrier is completely environmental-friendly before and after usage and can be activated mechanically or electrically to generate a huge amount of heat in a closed space. It contains both fuel materials to release energy by burning them, and oxygen generator materials to provide the required oxygen. Furthermore, it contains heat production controller and heat consumption controller materials to be safe. The energy carrier may be occupied in a package as a thermal battery that can be removably placed within or removed from a self-heating product to heat a content such as food, beverage, clothes, food delivery bag, buildings, etc. The thermal battery is a single-use heater and can be brought back to the producer company to be recharged by solar energy after the usage.

The invention relates to a feed tank for use in a high-pressure system, said feed tank having a hollow space (3) for accommodating food items, a wall (1) and a temperature-control device (5). The invention further relates to a method for the simultaneous high-pressure and temperature treatment in a high-pressure tank.

A portable food warmer comprises a collapsible plastic dish and a warming cover. The warming cover comprises an expandable material having an elastic periphery and a plurality of heating elements. A temperature controlling mechanism is disposed between the power supply and warming cover.

The present invention provides a multifunctional rechargeable heat preservation lunch box, including an inner box, an outer box, a rice basin, and an upper cover, where the inner box is fixed on the outer box, the rice basin is placed in the inner box, and the upper cover and the inner box are detachably mounted; a battery is arranged at the bottom of the outer box, a waterproof display screen, a PCBA, and a waterproof sealing cover are mounted on a side edge of the outer box, a heating plate and a heat insulation sheet are mounted at the bottom of the inner box, and the PCBA is electrically connected to the display screen, the heating plate, and the battery. According to the present invention, a plurality of problems existing in a traditional heat preservation lunch box are solved.

A heating lunch box includes a food box for accommodating food, a heating module for heating the food box, an interaction module, and a processor coupled to the heating module and the interaction module. The processor is configured for performing the following operations: obtaining a power-on instruction, in response to the obtained power-on instruction, controlling the interaction module to display an initial interface, and the initial interface at least including a first time setting control; when a trigger event of the first time setting control is detected, controlling the interaction module to display a time selection interface; obtaining a set time from the time selection interface; controlling the interaction module to display a heating interface based on the set time; and driving the heating module to heat the food box.

A construct includes at least one panel for supporting a food product, the at least one panel formed from a laminate structure having a base layer, a conductive layer, and a surface film. The construct further includes at least one spacing feature extending downwardly from the at least one panel for supporting the at least one panel a distance above an induction source for attenuating heat transferred to the food product in response to an oscillating magnetic field interacting with the conductive layer of the laminate structure.
