[0004] According to the manufacturing process, the coconut meat dietary fiber needs to be heated and pressed in the manufacturing process to remove part of the oil in the coconut meat.In addition, the oil content of the oil-removed material needs to be controlled in the crushing stage, and the oil content has a great influence on the particle size of the coconut fiber after crushing, and the particles are easy to stick together when the oil content is too high, and fine particles cannot be obtained, and the loss of coconut flavor in food taste will occur when the oil content is too low.Therefore, the process temperature and production process are controlled to control the oil content and the proportion of different chain length components in the laboratory and specific production process.In order to provide data support for process adjustment, and control of coconut meat dietary fiber and coconut fiber material food production process, volatile substances in the material need to be separated and analyzed quickly by gas chromatograph, and the composition and content of volatile substances are effectively determined to guide the experimental process and specific production process.At present, there is no corresponding device to extract volatile substance components of coconut meat dietary fiber and dietary fiber mixed food (hereinafter referred to as dietary fiber mixed food) combined with the sampling tube of gas chromatograph, so that the separation of volatile substances and the determination of specific content are more troublesome, and the test result is inaccurate.

[0005] Therefore, a coconut meat dietary fiber volatile substance separation device is designed, which can be used with the sampling tube of gas chromatograph to separate relatively pure volatile substances from the dietary fiber mixed food for gas chromatograph analysis. UTILITY MODEL CONTENT

[0007] The technical scheme of the utility model is implemented as follows:

[0009] When the above scheme is used, the dietary fiber mixed food is loaded into the food groove, the tube cover is placed into the tube cover groove, the sampling tube is inserted into the air seal ring in the cylindrical groove, the bottom of the sampling tube is pulled out through the through hole and is a certain distance from the tube cover, then the bottom sealing cover is installed, the top sealing cover is installed, the top sealing cover and the bottom sealing cover are connected through the ventilation mechanism. According to the specified temperature, the heating mechanism is used to heat the inside of the heating box. The ventilation pipe is connected to the external vacuum pump, the ventilation valve is opened, and the external vacuum pump starts to extract the gas in the bottom sealing cover, so that the air pressure in the bottom sealing cover and the top sealing cover is lower than the atmospheric pressure, a negative pressure is generated, and the air pressure in the bottom sealing cover is monitored in real time through the air pressure sensor. When the specified negative pressure value is reached, the ventilation valve is closed, the connection between the inside of the bottom sealing cover and the inside of the top sealing cover is closed through the ventilation mechanism, and the vacuum pump is stopped. Under the condition of negative pressure, the generated volatile substances of the dietary fiber mixed food begin to accelerate volatilization, which also contains the water vapor generated by the water contained in the dietary fiber food, and the volatile substances and water vapor begin to fill the inside of the bottom sealing cover and the inside of the sampling tube with the tube opening downward. Due to the continuous volatilization and evaporation of the dietary fiber mixed food, the air pressure in the bottom sealing cover begins to increase, and when the negative pressure value fed back by the air pressure sensor reaches the required opening degree, the top sealing cover is removed, the sampling tube is pressed downward to contact the tube cover by hand, and then the sampling tube is rotated to tighten the tube opening of the sampling tube and the tube cover. At this time, the volatile substances are effectively collected in the sampling tube, and the composition is controllable. Finally, the bottom sealing cover is removed, the sampling tube is pulled out from below the through hole, and is transferred to a gas chromatograph for analysis.

[0010] The device can effectively control the heating temperature of the food groove by setting the heating box, the food groove and the heating mechanism, and can realize the separation conditions of the dietary fiber mixed food at different temperatures.

[0011] The device can realize the separation conditions of the dietary fiber mixed food at different negative pressure conditions by setting the bottom sealing cover with the air extraction function and the air pressure detection function, and can accelerate the volatilization speed of the volatile substances of the dietary fiber mixed food under the negative pressure condition, thereby improving the separation efficiency.

[0012] The device controls the opening and closing of the bottom sealing cover and the top sealing cover through the ventilation mechanism, so that the pressure between the bottom sealing cover and the top sealing cover is consistent when the negative pressure is extracted, and the bottom sealing cover is prevented from being pulled out downward due to the lower air pressure than the top sealing cover.

[0013] The device seals the end of the sampling tube by setting the top sealing cover, so that when the volatile substances are separated, the whole sampling environment is kept from leaking, preventing air from entering the whole sampling environment, keeping the air inside the sampling tube scarce enough to accommodate the required collected volatile substances. When the top sealing cover is removed after sampling, the multiple air seals can effectively prevent external air from quickly entering the bottom sealing cover, and the setting of the multiple air seals can allow the sampling personnel to push the sampling tube down to connect with the tube cover to reduce the time for external air to enter the sampling tube, effectively improve the sampling purity in the sampling tube, and make the sampling purity of the volatile substances controllable.

[0015] When the bottom sealing cover and the top sealing cover need to be connected, the screw rod head is rotated outwardly to move the screw rod and the air seal column outwardly, so as to expose the lower air hole and make the lower air hole connected with the upper air hole through the horizontal air hole. When the bottom sealing cover and the top sealing cover need to be disconnected, the screw rod head is rotated inwardly to move the screw rod and the air seal column inwardly, so as to block the lower air hole, and the middle sealing ring is pressed tightly by the screw rod head to ensure that the whole bottom sealing cover is isolated from the outside air. It should be particularly noted that although the machining error may cause the air seal column to fail to completely close the lower air hole and the horizontal air hole, it can effectively slow down the speed of the air entering the bottom sealing cover through the upper air hole when the top sealing cover is opened, providing sufficient operation time for the sealing of the sampling tube and the tube cover.
