Abstract

The invention relates to the technical field of food processing, in particular to a food heating thermal bag. The food heating thermal bag comprises a bag body, a food box and a heating device. The bag body comprises a bag pocket, an inner tying opening and an outer tying opening. The bag pocket comprises a heat preservation layer on the outer side and a protection layer on the inner side. An annular graphene heating belt of the heating device is arranged between the heat preservation layer and the protection layer, and comprises a flat storing battery, a graphene heating belt, a temperature control device, a control panel and a charging opening. The storing battery provides electric power for the heating belt. The temperature control device monitors and controls the temperature in the bagto be maintained in the set temperature range in real time. The heat preservation temperature range is set by the control panel to control the power source of the heating belt and the temperature control device. The food heating thermal bag is internally provided with the graphene heating device, thermal energy is continuously compensated, and therefore the food in the bag can be maintained within the set temperature range, temperature and taste of the food can be guaranteed, edible experience and appetite are improved, and nutritional supply and health of dining staff are guaranteed.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a food heating and heat preservation bag. Background technique [0002] Chinese people have the habit of eating hot meals and hot dishes. However, it is difficult for many field workers or those who need to work continuously during meal times to go home or eat in restaurants and cafeterias, and have to carry food and beverages to the workplace for consumption. It is necessary to ensure that the food they carry can still maintain a certain temperature during meals. At present, in the absence of secondary heating conditions, people usually use thermos cups to carry food. However, the thermos cup will also lose the proper eating temperature of the food due to long-term slow heat dissipation, which will affect the eating experience and appetite, and then affect the nutritional supply and health. Contents of the invention [0003] In order to solve the technical problem th...
