College canteen fast food self-service vending device and method applying radiation heat exchange

Abstract

The invention discloses a college canteen fast food self-service selling device and method applying radiation heat exchange, and belongs to the field of food storage and selling. The device adopts a structure similar to a self-service vending machine and is divided into a fast food self-service area and an appointment area, and food in the self-service vending machine is kept warm by combining a heat radiation principle, so that the aim of relieving crowding degree of people in a canteen peak period is fulfilled. Main components comprise a snake-shaped radiation water pipe, a vending machine outer wall, a heat preservation layer, a meal taking cabinet, a water inlet, a water outlet and the like. Before use, hot water obtained by being connected with a hot water pipeline of a school canteenboiler room provides a heat source for the S-shaped radiation water pipe. During use, heated water in the radiation water pipe radiates and heats food, and meanwhile, the radiation water pipe is combined with an existing heat insulation material to preserve heat of the food. For teachers and students who are not willing to queue up for waiting, the teachers and students take away heat-preservation food by scanning codes through mobile phones, and the working and learning efficiency in a campus is improved.

Description

technical field [0001] This patent relates to a fast food self-service vending device and method in a university cafeteria using radiation heat exchange, which belongs to the field of food storage and vending. Background technique [0002] All objects in nature are constantly emitting radiant energy, while absorbing radiant energy from other objects and converting it into heat energy. The heat transfer between objects by thermal radiation is called radiation heat transfer. If radiative heat transfer is carried out between two objects with different temperatures, the result of the heat transfer is that the high-temperature object transfers heat to the low-temperature object, which is also called thermal radiation. Heat radiation is one of the basic ways of heat transfer. With the development of science and technology, people's life is gradually becoming automated, and self-service vending has now become a new and more convenient way of buying and selling. Research shows th...

Patent CN201310308439.6 relates to an intelligent and high-efficiency catering vending machine, including an ordering and charging operating system, an electric control system, a refrigeration system, a constant temperature storage system, a heating system, a drop-type output system and a cabinet body, and the meal-taking window is fixed on the cabinet body On the door leaf, the lower rice guide plate is fixed under the output mechanism. The boxed meal can be taken out from the tray through the lower rice guide plate to the window where the meal is taken out. The push rod stretches and retracts to complete the reciprocating action of sending the box lunch that needs to be heated into the microwave oven for heating. However, heating food immediately will cause energy waste, and the radio waves in the microwave oven will cause certain damage to the human body.
