Description

Technical Field

[0001] This utility model patent relates to an automatic evaporation and drying device for testing the total migration of food contact materials and products, and more particularly to an automatic evaporation and drying device for testing the total migration of food contact materials and products, which is used for transferring evaporation dishes by a robotic arm and can automatically replenish water to the water bath. Background Technology

[0002] The evaporation process for measuring the total migration of food contact materials and articles involves evaporating 200 ml simulated liquids obtained after migration tests in a water bath with a boiling point of approximately 10 degrees Celsius. This is one of the most repetitive and labor-intensive steps in the total migration measurement of food contact materials and articles. During the experiment, after the migration test, an evaporating dish containing 200 ml of simulated liquid needs to be removed from the sample rack and placed on the water bath. After the simulated liquid has completely evaporated, the evaporating dish is removed from the water bath and placed on the rack, and then another evaporating dish containing 200 ml of simulated liquid is placed on the water bath. During the operation of the water bath, the water level continuously decreases, requiring manual replenishment by tilting a container. After replenishment, the water temperature drops instantly, reducing evaporation efficiency. Furthermore, if left unattended, the water in the water bath may boil dry, leading to equipment damage and, in extreme cases, a fire. This experimental process is extremely labor-intensive and time-consuming, and poses certain safety hazards. Therefore, there is an urgent need to design an automated evaporation device suitable for measuring the total migration of food contact materials and articles.

[0003] In order to liberate people from long-term repetitive manual labor and improve the overall detection efficiency of total migration, it is of great significance to design an automatic drying device for testing the total migration of food contact materials and products, addressing the problems existing in the actual testing process. Summary of the Invention

[0004] This invention addresses the aforementioned problems by providing an automatic evaporation and drying device for testing the total migration of food contact materials and products. To achieve the above objectives, the technical solution of this utility model is: an automatic evaporation drying device for testing the total migration of food contact materials and articles, characterized in that it comprises a rack module, a water bath evaporation drying module, a transmission module, a water replenishment module, and an automatic control system module; the rack module includes an evaporation dish storage rack and a water bath body support, each of which is evenly divided into several areas; the water bath evaporation drying module includes a water bath body, a heating rod, and a temperature controller, the heating rod and temperature controller being disposed within the water bath body cavity; the transmission module includes a robotic arm gripper, a robotic arm base, and a ground sliding track; the water replenishment module includes a water level monitor and a pure water supply pipe, the pure water supply pipe being disposed within the water bath body cavity; the automatic control system module includes a setting module for setting the temperature inside the water bath and the time for removing and placing evaporation dishes; the transmission module is located in the middle position, the evaporation dish storage rack and the water bath body support are divided into two groups and disposed on both sides of the transmission module, and the water bath evaporation drying module is mounted on the water bath body support. The rack module is divided into an evaporating dish storage rack and a water bath support, each equally divided into 6 areas. Each evaporating dish storage rack and water bath has 8 evaporating dish storage compartments. The water bath evaporation module has 6 water baths, each equipped with a heating rod and a temperature controller. The heating rod is U-shaped, and the signal output of the temperature controller is connected to the automatic control system module. The transmission module includes a robotic arm base, a robotic arm gripper, and a ground sliding track. The length of the ground sliding track covers the length between the evaporating dish storage rack module and the water bath support. The water replenishment module includes a water level monitor and a pure water supply pipe. The pure water supply pipe is connected to the water bath, and the water level monitor is installed on the inner wall of the water bath. The output of the water level monitor is connected to the automatic control system module. The evaporating dish rack module includes an evaporating dish rack handle, an evaporating dish rack, and evaporating dishes. The evaporating dish rack handle is located at the center of both ends of the evaporating dish rack. Several circular hole positions are provided on the evaporating dish rack, and the evaporating dishes are placed on the circular hole positions.

[0005] The beneficial effects of this invention are as follows: The use of a robotic arm and a ground-mounted sliding track replaces the manual transfer of the evaporating dish, thus freeing up manpower to a certain extent. This device overcomes the shortcomings of traditional water baths, where manual replenishment via container pouring is required as the water level decreases, causing a sudden drop in water temperature and reducing evaporation efficiency. Furthermore, unattended operation can lead to the water in the water bath boiling dry, resulting in equipment damage and, in extreme cases, a fire hazard. Attached Figure Description
