Description

Technical Field

[0001] The utility model relates to the technical field of bread baking, in particular to a recovery sampler for bread baking gas. Background Art

[0002] During the bread baking process, the dough releases various gases during the fermentation and baking stages, such as carbon dioxide, water vapor, volatile organic compounds (VOCs), etc. Understanding the composition and release amount of these gases is of great significance for optimizing the baking process, improving bread quality, and food safety control; therefore, it is necessary to sample during the bread baking process.

[0003] Currently, the sampling method and sampling equipment for bread baking gas are very simple. Only by placing the sampling tube directly at the exhaust port of the baking equipment for sampling. However, when sampling in this way, not only are the high-temperature gases likely to scald the staff, but it is also difficult to ensure that no external gas is mixed in during the sampling process. In view of this, we propose a recovery sampler for bread baking gas. Content of the Utility Model

[0004] The purpose of the utility model is to provide a recovery sampler for bread baking gas to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A recovery sampler for bread baking gas includes a base. Two side plates are fixed on the top of the base, and two cross plates are fixed between the two side plates; fixing holes are opened at the centers of the cross plates, and a hollow recovery tank is installed between the two fixing holes; a gas pump is installed at the rear side of the top of the base; a hollow sampling bottle is installed at the front side of the top of the base.

[0007] An air inlet of the gas pump is installed with an air inlet pipe for connecting a bread baking box.

[0008] A connecting pipe is installed at the top of the recovery tank. A first valve is installed on the connecting pipe, and the first valve is communicated with an exhaust port of the gas pump; an exhaust pipe is installed at the bottom of the recovery tank, and a second valve is installed on the exhaust pipe.

[0009] An insertion pipe is installed at the rear end of the sampling bottle. The insertion pipe is in plug-in fit with the end of the exhaust pipe. A third valve is installed on the insertion pipe, and an air nozzle is installed at the front end of the insertion pipe. A detachable sealing cover is provided at the air nozzle.

[0010] Preferably, a support block is fixedly installed at the front side of the top of the base, and a support groove for placing the sampling bottle is opened at the top of the support block.

[0011] Preferably, a thread groove is opened on the outer wall of the air nozzle, and the sealing cover is threadedly connected with the thread groove.

[0012] Preferably, a pressure gauge is installed on the top of the recovery tank, and the pressure gauge is fixedly connected to the recovery tank through a flange.

[0013] Preferably, the cross-sectional shape of the fixing hole is circular, and the size of the fixing hole is adapted to the size of the recovery tank.

[0014] Preferably, the sampling bottle is transparent, and the sampling bottle and the intubation tube are integrally formed.

[0015] Preferably, the recovery tank is fixedly connected to the horizontal plate by bolts, and the recovery tank is made of stainless steel.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] By providing an air pump, a recovery tank and a sampling bottle: under the action of the air pump, the gas discharged from the exhaust port of the bread baking equipment is directly extracted, and the gas enters the recovery tank through the connecting pipe for recovery; when sampling, the second valve is opened, and the gas in the recovery tank moves into the sampling bottle. At this time, the air in the sampling bottle is squeezed out and discharged to the outside through the air nozzle, and the sealing cap is tightened on the air nozzle synchronously, and the baking gas remains in the sampling bottle. After closing the third valve, the baking gas stays in the sampling bottle. This design not only facilitates the recovery and sampling of bread baking gas, but also has low operation risk during sampling, and at the same time ensures that no external gas is mixed in during the sampling process.

[0031] In this embodiment, a support block 12 is fixedly installed at the front side of the top of the base 1, and a support groove for placing the sampling bottle 4 is opened at the top of the support block 12. The setting of the support groove facilitates the stable placement of the sampling bottle 4 and ensures the stability during the sampling process.

[0032] In this embodiment, a thread groove is opened on the outer wall of the air nozzle 42, and the sealing cap 43 is threadedly connected to the thread groove. The threaded connection method facilitates the disassembly and assembly of the sealing cap 43 and improves the convenience of sampling.

[0033] In this embodiment, a pressure gauge 32 is installed on the top of the recovery tank 3, and the pressure gauge 32 is fixedly connected to the recovery tank 3 through a flange. This design is conducive to the user observing the pressure condition inside the recovery tank 3.

[0034] In this embodiment, the cross-sectional shape of the fixing hole is circular, and the size of the fixing hole is adapted to the size of the recovery tank 3. This design facilitates the stable installation of the recovery tank 3 at the fixing hole.

[0035] In this embodiment, the sampling bottle 4 is transparent, and the sampling bottle 4 and the intubation 40 are of an integrally formed structure. The integrally formed sampling bottle 4 and intubation 40 have better connection strength, and the transparent design facilitates observing whether the inside of the sampling bottle 4 is clean.

Subsequently, the user turns on the power supply of the air pump 2, and the air pump 2 starts to work. At this time, the gas discharged from the exhaust port of the bread baking device enters the intake pipe 20, and enters the recovery tank 3 through the connecting pipe 30. At the same time, the gas enters the sampling bottle 4 through the exhaust pipe 33 and is discharged to the outside through the air nozzle 42. After maintaining the gas flow for a period of time, the gas in the sampling bottle 4 is discharged. At this time, the user tightens the sealing cap 43 on the air nozzle 42, and the baking gas is intercepted in the sampling bottle 4. At this time, the user turns off the power supply of the second valve 34 and the third valve 41, and the baking gas is intercepted in the sampling bottle 4. The user can then remove the sampling bottle 4, and the sampling is completed. At the same time, under the operation of the air pump 2, the baking gas continues to be transported into the recovery tank 3.
