According to the invention, the baking curve is issued by the server to control the operation process of drying the weight of the material, so that the tracing difficulty caused by human factors can be avoided and unnecessary disputes can be eliminated. Meanwhile, the baking curve is kept secret, and advanced baking technology can enhance the competitiveness of the product in the market.
In some embodiments of the present invention, the present invention is provided with the pressure sensor 200 in the material carrier for measuring the weight of the loaded material, and displaying the weight of the loaded material to the worker and the server part 100, the server part 100 displays and stores the weight information of the material, the worker inputs the material type and the baking place in the host machine 300 after the loading is completed, and the worker can save the material type and the baking place to the host machine 300 or the server part 100 in advance, and change the material type when the material is replaced; the server portion 100 stores baking curves, which include baking curves of various materials in each region, and the baking curves corresponding to the materials in each region are different, because the baking curves of the same material in different regions are not necessarily identical, and the characteristics and water content of different materials are different, and the corresponding baking curves are different. The same material has different water contents due to different growing environments of different producing areas, and the corresponding baking curve also changes along with the different water contents. The loading weight of the material is visible and transparent to the host 300 and between the server portions 100. The baking curve is a host operation parameter for controlling the temperature of the baking room, the dehumidifying time node and the dehumidifying time according to the weight and time of the materials in the material carrier. The filling personnel can fill one hundred kilograms or two hundred kilograms of equal weight materials according to the standard, and can also be any weight value at random. The operation parameters corresponding to the baking curve can be one hundred kilograms or two hundred kilograms, and can also correspond to any weight. Namely, a certain amount of materials respectively correspond to corresponding baking curves. The server portion 100 remotely controls the delivery of a firing profile to the host computer 300 based on the weight of the charged material, and the host computer operates the firing process based on the firing profile. The debugging is not needed to be participated manually, so that the cost is saved.
In the drying process, the baking time and the dehumidification are generally controlled through temperature and humidity detection data in the baking room, and temperature and humidity differences exist at different positions in the space of the baking room, so that the detected temperature and humidity are not accurate enough, and the baking quality difference or poor baking quality can be caused. Because the drying is to evaporate and separate the water contained in the material as soon as possible in an artificial way. The essence of drying is to remove the moisture of the material. Taking the rose as an example, the initial moisture content of the rose is 75%, and the final moisture content after drying is 14%, then 61% of the moisture is lost in the drying process, namely the corresponding weight is lost. If one hundred kilograms of rose is to be baked, the corresponding moisture is lost after the baking, thirty-nine kilograms of rose is used as the target parameter of qualified baking and finished baking. In the process, when the material is changed from one hundred kilograms to seventy kilograms, the baking curve is operated to remove the moisture, the temperature is raised again after the moisture is removed for a certain time, the weight of the material is changed to fifty kilograms, the moisture is removed again, and the like, and a series of processes are performed until the target weight is reached, and the drying is completed.
The invention also provides a human body thermal sensation detection part in the curing barn, when the human body thermal sensation detection part detects that a person is in the curing barn, the host machine can not start the heat pump and give an alarm to prompt, so that accidents are avoided.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
