Microwave meal box

Abstract

The invention discloses a microwave meal box. The microwave meal box comprises a meal box body, exhaust grooves are formed in the two long side edges of the meal box main body, a covering film is pressed on the periphery of the sealing edge of the meal box main body and covers the exhaust grooves to form a sealing opening of the covering film and the meal box main body, wherein the technological parameters of pressing the covering film on the meal box main body are as follows, the film pressing temperature is less than or equal to 200 DEG C, and the film pressing time is less than or equal to 10 seconds. Air can be exhausted when food is heated to a proper state, so that the food is heated more effectively and uniformly, the heating time is shorter, moisture is not lost after heating is completed, the humidity is kept on the surface of the food, the original eating taste of the food is kept, exhaust does not generate abnormal sound, the food and the soup cannot overflow out of the meal box, and the microwave oven cannot be polluted or the food cannot be polluted due to contact between the food and the microwave oven; and the food heated by the microwave oven is wider in variety, and the microwave meal box is also suitable for delivery, heating and selling by using a self-service vending machine with a microwave oven heating function.

Description

Technical field [0001] The present invention relates to the field of catering techniques, and more particularly to a microwave dining box. Background technique [0002] The packaging membrane of the microwave heating box is fully enclosed, and there is no design of the exhaust hole. Since the exhaust hole is not designed, the food in the microwave heating process is overflow due to microwave heating, steam expansion, appears The sealing membrane has been broken by vapor, and the soup and food spillage have caused contamination microwave or food and microwave ovens that can not be eaten. When the packaging scheme is heated, it needs to be puncture the cover film with sharp objects to avoid water vapor to break the meal box. During the heating, since the resulting water vapor runs out from the tiered hole, the heated food is prone to surface drying, affecting the heating effect and eating taste. [0003] In the existing plan, there is also a microwave food box for the exhaust hole,...

AI Technical Summary

Problems solved by technology

During the heating process, the water vapor generated escapes from the punctured hole, and the surface of the heated food is prone to dryness, which affects the heating effect and eating taste

[0003] In the existing solutions, there are also microwave food lunch boxes designed with vent holes, but they are not effectively sealed and covered. After microwave heating, the water vapor is usually released in 10-15 seconds at the beginning of heating, and the moisture in the food cannot be guaranteed. The water vapor in the cavity of the lunch box is discharged and the surface of the food is too dry, which affects the heating effect and taste

Food is easily in contact with air after microwave heating, resulting in food safety risks
