[ first embodiment ] A method for manufacturing a semiconductor device

Referring to fig. 1, a first embodiment of the present invention provides a method for displaying shelf life of food. As shown in fig. 1, the method for displaying shelf life of food includes, for example: step S11 and step S13.

Step S11: applying an edible coating to a designated location of a target food product;

step S13: sending shelf-life data to a laser emitter to emit laser light by the laser emitter to illuminate the edible coating of the target food based on the shelf-life data to display a shelf-life corresponding to the target food on the edible coating.

In particular, reference is made to target food products such as ready-to-eat food products, for example, target food products such as cakes, biscuits, steamed bread, steamed stuffed buns and the like. The designated position mentioned is, for example, a certain area selected based on the outer surface of the target food, for example, when the target food is a cake, the designated position mentioned is, for example, the bottom surface of the cake, and this bottom surface may be understood as the other surface opposite to the surface on which the birthday happy jam is coated. When the target food is referred to as a steamed stuffed bun, the designated position is referred to as the bottom surface of the steamed stuffed bun, i.e., the surface contacting the food steamer, but the invention is not limited thereto, and other surfaces of the target food can be referred to. The edible coating mentioned above is, for example, a transparent coating, and by providing the edible coating as a transparent coating, the edible coating cannot be repeatedly applied, i.e., if repeatedly applied, the edible coating applied last time and the shelf life displayed thereon cannot be covered, thereby further ensuring the reliability of the shelf life of the food.

Further, the edible coating layer includes, for example, an edible solution and an edible substrate mixed in the edible solution and discolored under the laser irradiation. For example, the mentioned edible solution is gelatin, and the mentioned edible substrate is instant yeast, wherein the instant yeast is a solution formed by mixing the gelatin and the instant yeast, which is edible material for human body, contains abundant protein, essential amino acid, B vitamins, minerals, dietary fibers and the like, and is coated on the target food, so that the target food can be added with nutrient components and simultaneously the taste of the food can be increased.

It should be noted that the present invention is not limited to specific materials of the edible coating, and other edible materials may be used as long as the condition that the edible coating is colorless and transparent in normal state and can change color under laser irradiation is satisfied. The foregoing examples provide the edible coating material as a mixture of instant yeast and gelatin only for better illustration of this embodiment, but in other embodiments the edible coating may be composed of a single material, or more than two materials.

Further, step S11 includes, for example, sending a coating instruction to the manipulator, so that the manipulator can interpret the coating instruction to obtain the position information corresponding to the designated position, and coating the edible coating based on the position information. The manipulator mentioned here is, for example, a manipulator existing in the prior art, which mainly implements a liquid material coating function, but in the prior art, a manipulator that implements a liquid material coating function is applicable to this embodiment, and it is understood here that a liquid material corresponding to an edible coating related to this embodiment is put into a container, the manipulator is connected to the container, and the manipulator can control opening and closing of an opening of the container, the manipulator controls the opening of the container to close before receiving no coating instruction, and after receiving a coating instruction, the manipulator controls the opening of the container to open, and the manipulator coats the liquid material flowing out from the container to a designated position of a target food, thereby forming the edible coating.

Further, as shown in fig. 2, the sending of the shelf life data to the laser emitter mentioned in the step S13 includes, for example, the steps S131 and S133.

Step S131: responding to the input operation of the user to obtain an input numerical value as the number of quality guarantee days; and

step S133: and reading the current corresponding date information and time information as production information, and sending the production information and the data corresponding to the quality guarantee days as the quality guarantee period data to the laser transmitter.

The mentioned user input operation is, for example, a filling operation of the user in the information input box. It can be understood here that the shelf life data includes data corresponding to the number of days of shelf life, which is a parameter input by the user on the human-computer interface, and date information and data corresponding to the time information, which are parameters read in real time, so that the process of obtaining the shelf life data is simplified, and the operation efficiency is improved.

For better understanding of the present embodiment, a specific embodiment of the method for displaying shelf life of food provided by the present embodiment is illustrated below with reference to fig. 3.

For example, after a merchant finishes making a cake, the shelf life of the cake needs to be represented. At this time, a merchant operates on a PC, for example, a mouse clicks an interactive interface, the PC responds to a user mouse click operation to generate a coating instruction and sends the coating instruction to a manipulator, the manipulator analyzes the coating instruction to obtain position information of a position to be coated, and coats a cake to form an edible coating based on the position information, then the merchant inputs the number of days of quality of the cake on the interactive interface of the PC, the PC acquires current date information and time information in real time, and sends the received number of days of quality and data corresponding to the current date information and the time information to a laser transmitter, the laser transmitter sends laser to irradiate the edible coating based on the received data, the place irradiated by the laser of the edible coating changes color to show the quality guarantee period, and accordingly, the display of the quality guarantee period of the food is completed.

It should be noted that the aforementioned action of applying the edible coating can also be performed manually, that is, when the number of food is small, the edible coating can be applied manually, thereby further reducing the cost.

In summary, according to the food shelf life display method provided by the embodiment of the invention, the edible coating is coated at the designated position of the target food, then the shelf life data is sent to the laser transmitter, the laser transmitter emits laser light to irradiate the edible coating based on the shelf life data, so that the edible coating displays the shelf life corresponding to the target food, the problems that in the prior art, bulk food has no shelf life identifier, and shelf life labels are attached to packaging bags and are questioned by customers that the shelf life labels of the food are replaced, so that the food sales volume is influenced can be avoided, the shelf life is displayed on the edible coating, so that merchants cannot change or replace the shelf life of the food, the confidence of consumers on the food is increased, and the food purchased by the consumers is guaranteed to be the food in the shelf life; the use of a shelf life label is avoided, and the cost is reduced; the whole process is simple and convenient, the efficiency is high, and no additional field is needed; the material of the edible coating is selected from yeast solution, which can add nutrient components to the food and can also increase the taste of the food.
