Description
Technical field
The utility model relates to the food heat-insulation technical field, is specifically related to a kind of phase-change thermal-storage that is applied to the human food snack industry and takes out case.
Background technology
Fast food (a quick lunch; A snack; Fast food) be meant food ready-made in advance and that can provide client to eat rapidly, Hong Kong and Taiwan's one band obtains translations fast food, instant, convenient, as hamburger, packed meal etc.Fast food is by the processing of bakery and confectionery production or big-and-middle-sized food and beverage enterprise, when it has popular, joint, advantage such as convenience.Along with the high speed development of modern food catering trade, increasing foreign formula and Chinese fast food appear in the middle of the daily life in recent years.For example: USA and Europe fast food giants such as KFC, McDonald, Pizza Hut, Burger King; Chinese fast food new recruits such as Dong Fangjibai, real skill and aunt's boiled dumpling.In order to adapt to the allegro life of modern society, a lot of fast food restaurants all provide one after another takes out or sends outside service.This newly-increased sales mode can be delivered to customer's family, the appointed places such as unit, playground of handling official business to fast food the very first time.The service of sending outside of this order formula has not only been saved the time, has also allocated the production of fast food to a certain extent, has optimized the utilization of resources effectively.
Sending outside in the middle of the process, because the time goes up at interval and the distance on the space, all can there be decline to a certain degree in the temperature of food.Generally send distance outside in 15min, the temperature of food can descend about 25 ℃.If weather is sombre, environment is abominable, and the temperature of decline can be bigger.So control its temperature drop, be incubated the difficult problem in sending outside into fast food to greatest extent.
Food egress of heat in air has two kinds of method 1. transfer of heats--the heat conduction of container; 2. the heat convection of food and air.The blocking-up food and the heat conduction of container and the heat convection of inhibition and air are the making principles of conventional insulation can.Chang Yong food take-out insulation can in the market, most widely used is to adopt polystyrene (EPS), extrusion moulding type polystyrene (XPS) or polyurethane (PU) as warm material.It is added other by warm material supplementary material and the poly-thing that contains mix injecting catalyst simultaneously by heating, and the extrusion molding extrusion molding has very low coefficient of thermal conductivity then, reduces heat conduction effectively; Casing is the fully enclosed square or rectangular, and good sealing property is arranged, and effectively stops the inner air and outer air heat loss through convection, though certain insulation effect is arranged.But this type of insulation can is owing to be passive heat insulation, initiatively heat supply, so can not guarantee the temperature of food for a long time, its effect has certain limitation.
The utility model content
The utility model discloses a kind of phase-change thermal-storage of phase-transition heat-storage principle development that utilizes and take out case, it is passive heat insulation to overcome existing take-away case, initiatively heat supply and the defective of insulation for a long time, owing to adopted the phase-changing energy-storing heat release, its heat supply for a long time, insulation change the passive heat insulation initiatively heat supply that is.The casing impact resistance is strong, and there is special phase-transition heat-storage body layer the centre, is a kind of green new ideas product.Compare with traditional food insulation box, its temperature retention time is longer, and better heat preservation, and have the property monitored in real time with using with advantages such as heating, and has extensive market prospects.
A kind of phase-change thermal-storage is taken out case, comprise box container, be connected with case lid on it, it is characterized in that: be close to case shell inwall thermal isolation film is set, the interlayer between thermal isolation film and endogenous pyrogen is provided with the accumulation of heat ordered array of being made up of the phase-transition heat-storage body, described phase-transition heat-storage body ordered array adds thermal regenerator by resistance strain gauge, resistance strain gauge is connected with external source through lead, and temperature sensor places insulation to take out the endogenous pyrogen of case, is connected by lead with display instrument on being embedded in case shell outer wall.
Described phase-transition heat-storage body can be phase-transition heat-storage ball, phase-transition heat-storage pipe or phase-transition heat-storage sheet, canned phase change heat storage material in it.
Phase-change material in the described phase-transition heat-storage body is the combination of phase transition temperature at one or more phase-change materials of 50～90 ℃.
Advantage of the present utility model and good effect are: (1) good heat insulating: adopt phase change heat storage material in the phase-transition heat-storage body, store latent heat of phase change to greatest extent, effectively initiatively heat release insulation; The structure design of specialty is guaranteed the leak tightness of casing effectively to stop the inner air and outer air heat loss through convection; The case shell adopts the weak strong engineering plastic materials of emissive capacity of absorption power, effectively reduces heat (cold) radiation and runs off; Case shell inwall has also increased the polyurethane thermal isolation film of a bed thickness 50mm, strengthens insulation.(2) intelligent monitoring, in time heating: adopt digital displaying meter to connect internal temperature sensor, monitoring box house temperature that can efficient real time is to guarantee that sending food outside is in the temperature required scope always.After temperature is lower than preset threshold, connect power supply immediately, the heat-storing sphere in the heating casing, effectively temperature control.(3) easy to operate, be widely used.
