Description

Technical Field

[0001] The present invention relates to the field of liquor brewing, and particularly to a fermented grains distillation monitoring system and method. Background Art

[0002] With the continuous development of the liquor industry, the requirements for quality control in the liquor production process are getting higher and higher. As a key link in liquor production, distillation efficiency and quality directly affect the quality of the final product. The heat transfer of fermented grains involves a complex process of heat and mass transfer in porous media. The traditional fermented grains distillation process mainly relies on experience and manual control, lacking precise scientific analysis methods, and unable to monitor the temperature distribution and heat transfer of fermented grains in real time and comprehensively, resulting in significant differences in the quality of liquor distilled from the same batch of fermented grains and difficulty in analyzing the reasons.

[0003] With the development of infrared thermal imaging technology, its application in the industrial field has gradually increased. When applying it to the monitoring of fermented grains distillation, due to the low transmittance of the infrared thermal imager through the fermented grains distiller, built-in monitoring is mostly used. Using this method, the characterization of the heat transfer characteristics outside the distiller is insufficient, and the monitoring device is easily affected by steam, resulting in inaccurate monitoring. Summary of the Invention

The transmittance of the distillation vessel to the infrared thermal imager meets the threshold. The distillation vessel is respectively connected to the condensation device and the steam generator device, and the infrared thermal imager monitors the heat change of the fermented grains sample during the distillation process.

[0009] Further, the condensation device is a serpentine condenser tube.

[0010] Further, the condensation device is 200 mm long and the diameter is 30 mm.

[0011] A fermented grains distillation monitoring method, comprising: Step 1: Load the fermented grains sample into the distillation vessel in the same way as the actual distillation process for filling the fermented grains. Step 2: Use an infrared thermal imager to monitor the heat change of the fermented grains sample during the distillation process.

Description of the Drawings

[0014] Figure 1 It is a schematic structural diagram of the fermented grains distillation monitoring system; Reference numerals: 1 is a steam generator device, 2 is an infrared thermal imager, 3 is a distillation vessel, 4 is a distillation bottom flask, and 5 is a condensation device. Detailed Embodiments

[0015] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0016] As Figure 1 shown, the fermented grains distillation monitoring system includes: a distillation vessel 3 for holding the fermented grains sample, a steam generator device 1, a condensation device 5 and an infrared thermal imager 2. The transmittance of the distillation vessel 3 to the infrared thermal imager 2 meets a threshold value, and the threshold value can ensure the imaging effect of the infrared thermal imager. The specific value can be set according to the actual situation. The distillation vessel 3 is respectively connected to the condensation device 5 and the steam generator device 1, and the infrared thermal imager 2 monitors the heat change of the fermented grains sample during the distillation process.

[0017] The distillation vessel can be made of single-layer stainless steel, heat-resistant glass, etc. In this embodiment, a high borosilicate glass material with excellent thermal conductivity (λ≥1.2W / m·K), heat resistance (temperature resistance ≥500°C) and optical transparency (visible light transmittance ≥90%) is used to construct a visual distillation experiment system for observing the filling situation of the fermented grains.

[0018] Specifically, the high borosilicate glass distillation vessel is cylindrical. A layer of grid-shaped blocking pieces is provided at the lower end of the glass tube. The glass tube is 200 mm long and 120 mm in diameter. This size design can accurately simulate the actual distillation characteristics of fermented grains while ensuring the structural compactness. The diameter of the blocking piece is 120 mm, and the mesh hole is 2 mm. This size configuration can not only effectively block the leakage of fermented grains but also ensure the smooth penetration of the gas at the bottom. The condensing device uses a serpentine condenser tube, which can ensure the condensing effect while ensuring the structural compactness. In this embodiment, the condensing device is 200 mm long and 30 mm in diameter, and the condensing water flow rate is 1 L / min.

[0019] Furthermore, it also includes a distillation bottom flask 4. The high borosilicate glass distillation vessel 3 is connected to the steam generator device 1 through the distillation bottom flask 4. The distillation bottom flask 4 can collect the condensed water generated during the distillation process, and improve the experimental accuracy by reducing the interference of the condensed water on the experiment.

[0020] The method for monitoring the distillation of fermented grains includes: Step 1: Load the fermented grain sample into the distillation vessel using the same fermented grain filling method as the actual distillation process. The fermented grain filling method is uniform filling or gas-seeing filling. Gas-seeing filling means that when there is steam in the distillation vessel, spread an appropriate amount of fermented grains to the position where the steam is generated. After spreading, if the steam no longer emerges, transfer to another position where the steam is generated and spread the fermented grains until the entire filling process is completed.

[0021] Step 2: Use an infrared thermal imager to monitor the heat change of the fermented grain sample during the distillation process. Since the same fermented grain filling method as the actual distillation process is adopted, the thermal imaging process in the experiment can be analogized to the thermal imaging process of the actual distillation, thus realizing the comprehensive monitoring of the temperature field of the distillation apparatus.
