[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0026] Example

[0027] like Figure 1-2 As shown, a multi-channel distillation device for detecting moisture in food includes a bracket 1, a toluene adding device and a plurality of moisture distillation measuring devices. The toluene adding device is assembled on the bracket 1 through a connecting frame assembly 3. The bracket 1 is provided with a plurality of heating components 2. The plurality of moisture distillation measuring devices are respectively arranged on the heating components 2 in a one-to-one correspondence and are respectively connected to the toluene adding device. The connecting frame assembly is provided with a visual detection assembly.

[0028] The working principle is: when it is necessary to measure the moisture in food, place the moisture distillation measuring device on the heating component 2, and turn on the heating component 2 at the same time to distill the moisture in the food inside the moisture distillation measuring device, and use the visual detection component to detect whether all the moisture in the food has been distilled out, and use the buzzer to remind the inspector to turn off the heating component 2.

[0029] The above technical solution can distill the moisture in the food inside the multiple moisture distillation measuring devices through the heating component 2, thereby improving the distillation efficiency, and at the same time use the visual detection component to detect the moisture in the food.

[0030] Preferably, the connecting frame assembly 3 includes a plurality of support rods 302 and a support plate 301 , the lower surface of the support plate 301 is connected to the toluene adding device, the upper end of the support rod 302 is connected and fixed to the support plate 301 , and the other end thereof is connected to the bracket 1 .

[0031] The working principle is as follows: by providing a support rod 302 and a support plate 301 , the toluene adding device is fixed above the bracket 1 , so that toluene can be added directly into the water distillation measuring device later.

[0032] The above technical solution can be used to install the toluene adding device above the bracket 1 by providing the support rod 302 and the support plate 301, so as to facilitate the subsequent addition.

[0033] Preferably, the toluene adding device includes a liquid storage tank 4, a micro water pump and a quantitative control valve 8. The liquid storage tank 4 is fixedly mounted on the support plate 301. A plurality of liquid outlet pipes connected to the liquid storage tank 4 are provided below the liquid storage tank 4. The quantitative control valve 8 is arranged on the liquid outlet pipe. The micro water pump is arranged on the liquid storage tank 4. The liquid outlet pipe is connected to the corresponding water distillation measuring device.

[0034] The quantitative control valve 8 is electrically connected to an external quantitative control instrument.

[0035] Among them, the visual detection component, the heating component 2 and the quantitative control instrument are connected to the external computer terminal, and the external computer terminal is electrically connected to the external buzzer alarm.

[0036] The working principle is: when toluene is added into the water distillation measuring device, the quantitative control valve 8 is controlled by the quantitative controller to control the quantitative amount of toluene to enter the water distillation measuring device through the liquid outlet pipe. After the addition is completed, when there is no need to add toluene, the quantitative control valve 8 is closed to complete the addition of toluene.

[0037] The above technical solution can realize the toluene addition operation of multiple water distillation measuring devices through a quantitative control valve, which is convenient and efficient.

[0038] Preferably, the water distillation measuring device includes a distillation flask 5, a water receiving tube 7 and a straight condenser 6. The distillation flask 5 is arranged on the corresponding heating component 2. The water receiving tube 7 is connected to the side outlet of the distillation flask 5. The straight condenser 6 is arranged above the water receiving tube 7 and is connected and communicated with the water receiving tube 7. The upper outlet of the distillation flask 5 is connected and communicated with the liquid outlet pipe.

[0039] The straight condenser 6 is fixedly assembled on the bracket 1 through a fixing bracket.

[0040] Wherein, the surface of the moisture receiving tube 7 is provided with scales.

[0041] The working principle is: when the moisture content of the food inside the distillation flask is measured, the toluene inside the liquid storage tank 4 is added to the moisture receiving tube 7 through a micro water pump. At the same time, in the process of heating the distillation flask, the moisture inside the food and the toluene evaporate together and enter the moisture receiving tube 7. After cooling and reflux through the straight condenser 6, the moisture and toluene inside the food are separated into layers in the moisture receiving tube 7. A small amount of methylene blue powder is added to the moisture receiving tube 7 in advance, and the methylene blue powder combines with water to turn blue, so that there is a color distinction between moisture and toluene, which is convenient for subsequent reading of the moisture content through the scale.

[0042] The above technical solution can be finally realized by arranging a distillation flask 5, a moisture receiving tube 7 and a straight condenser 6 to cooperate with each other, so that the toluene and moisture inside the distillation flask 5 enter the moisture receiving tube together.

[0044] The working principle is: when water vapor and toluene vapor enter the moisture receiving tube 7 together, they rise to the straight condenser to cool and reflux, and the toluene is on the upper layer of the water. As the toluene continues to flow into the moisture receiving tube, the toluene refluxes into the distillation flask. The visual detection component monitors the liquid level of the water. When the liquid level of the water remains unchanged within 10 minutes, the external buzzer alarm sounds an alarm to remind the monitoring personnel to turn off the heating component 2 and recycle the detected moisture receiving tube 7 and other devices.

[0045] The above technical solution can realize automatic monitoring of food moisture measurement by setting up a visual detection camera 11 and a mounting block 10, and monitoring and observing the liquid level of water inside the moisture receiving tube 7 in real time through the visual detection camera 11, and timely feeding back to the computer terminal, thereby reducing manual input and improving work efficiency.

[0047] The working principle is: The working principle is: By connecting the water inlet pipe and the water outlet pipe between multiple straight condensers 6 in series through the first water pipe, multiple straight condensers 6 are connected in series to form a condensation system. The inspector only needs to add cold water to the water inlet pipe of the straight condenser at the head end. After the cold water passes through multiple straight condensers 6, the water outlet pipe of the straight condenser 6 at the end returns to the cold water circulation system.

[0048] The above technical solution can facilitate the circulation and replacement of water inside the multiple straight condensers 6 by connecting the multiple straight condensers 6 in series, thereby improving the cooling efficiency of the device.

[0050] Among them, a refrigeration plate is arranged inside the cold water tank.

[0051] The working principle is: by setting up a cold water tank and a water pump outside, and using the water pump as the driving force of the water body, the water inside the straight condenser tube can circulate inside multiple straight condenser tubes, and absorb heat and cool the water vapor and toluene vapor.

[0052] The above technical solution can achieve the purpose of circulating the water inside a plurality of straight condensing tubes connected in series by providing a cold water tank and a water pump.

[0053] Preferably, the upper outlet of the distillation flask 5 is provided with a piston 9 for sealing it, and the lower end of the liquid outlet pipe is sealed and penetrates the piston 9.

[0054] The working principle is: when it is necessary to add the food to be tested, open the piston 9, put the food to be tested through the upper outlet of the distillation flask 5, and reinsert the piston 9 to ensure the sealing of the distillation flask 5.

[0055] The above technical solution can be provided with a piston 9, so that the inspector can easily put in food, which is convenient and quick.

[0056] Preferably, the bracket 1 includes a plurality of support legs 102 and a support base plate 101 , the upper ends of the plurality of support legs 102 are fixedly mounted on one surface of the support base plate 101 , and the plurality of heating components 2 are distributed in a ring shape on the other surface of the support base plate 101 .

[0057] The working principle is: by arranging multiple heating components 2 in a ring shape on the supporting base plate 101, and arranging a moisture distillation measuring device above the heating components 2, synchronous heating is achieved, and the purpose of moisture measurement of multiple groups of food is carried out together, thereby improving the efficiency of moisture detection.

[0058] The above technical solution can greatly improve the efficiency of measuring the internal moisture of various foods by providing multiple heating components 2 and correspondingly providing multiple moisture distillation measuring devices.

[0059] Preferably, the heating assembly 2 includes a placement groove and a heating wire, the heating wire is evenly spaced and distributed inside the placement groove, and the placement groove is arranged on the supporting bottom plate 101 .

[0060] The working principle is: by arranging the electric heating wire to heat the distillation flask 5, the heating degree is made more uniform, the heating effect is better, and the heating time is more conveniently controlled.
