Description

Technical Field

[0001] This utility model relates to the field of liquor brewing, specifically a monitoring system for the distillation of mash. Background Technology

[0002] With the continuous development of the baijiu industry, the requirements for quality control in the baijiu production process are becoming increasingly stringent. Distillation, as a crucial step in baijiu production, directly impacts the quality of the final product through its efficiency and quality. The heat transfer of the mash involves a complex process of heat and mass transfer through porous media. Traditional mash distillation processes rely primarily on experience and manual control, lacking precise scientific analysis methods. This makes it impossible to monitor the temperature distribution and heat transfer of the mash in real time and comprehensively, resulting in potentially significant differences in the quality of the distilled liquor from the same batch of mash, with the reasons for these differences being difficult to analyze.

[0003] With the development of infrared thermal imaging technology, its application in the industrial field is gradually increasing. When applied to the monitoring of mash distillation, because the mash still has low transmittance to infrared thermal imagers, built-in monitoring is often used. However, this method is insufficient for characterizing the heat transfer characteristics of the still's periphery, and the monitoring device is easily affected by steam, leading to inaccurate monitoring. Utility Model Content

[0004] In order to achieve comprehensive monitoring of the temperature field of distillation equipment, this utility model provides a monitoring system for the distillation of mash.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] The fermented mash distillation monitoring system includes: a distillation vessel for holding fermented mash samples, a steam generator, a condenser, and an infrared thermal imager. The transmittance of the distillation vessel to the infrared thermal imager meets a threshold. The distillation vessel is connected to the condenser and the steam generator respectively. The infrared thermal imager monitors the heat changes of the fermented mash samples during the distillation process.

[0007] Furthermore, the distillation apparatus is a cylindrical high borosilicate glass tube, with a mesh-like barrier sheet at the lower end of the glass tube.

[0008] Furthermore, the glass tube is 200mm long and 120mm in diameter, the barrier plate is 120mm in diameter, and the mesh size is 2mm.

[0009] Furthermore, it also includes a distillation flask, through which the distillation apparatus and the steam generator are connected.

[0010] Furthermore, the condensation equipment is a serpentine condenser tube.

[0011] Furthermore, the condenser is 200mm long and 30mm in diameter.

[0012] Compared with the prior art, the advantages of this invention are as follows: a simple experimental distillation apparatus is made using a glass distillation container with mesh and a steam generator, and the heat distribution is monitored in real time using an infrared thermal imaging device; based on the same filling method, the thermal imaging process in the experiment is used as an analogy to the thermal imaging process of actual distillation, thereby realizing comprehensive monitoring of the temperature field of the distillation apparatus; the entire experimental apparatus is simple to configure, updates data quickly, and is easy to operate.

[0014] Figure labels: 1 is a steam generator, 2 is an infrared thermal imager, 3 is a distillation vessel, 4 is a distillation bottom flask, and 5 is a condenser. Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0016] like Figure 1 As shown, the fermented mash distillation monitoring system includes: a distillation vessel 3 for holding fermented mash samples, a steam generator device 1, a condenser 5, and an infrared thermal imager 2. The transmittance of the distillation vessel 3 to the infrared thermal imager 2 meets a threshold, which 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 connected to the condenser 5 and the steam generator device 1 respectively. The infrared thermal imager 2 monitors the heat change of the fermented mash samples during the distillation process.

[0017] The distillation apparatus 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℃) and optical transparency (visible light transmittance ≥90%) is used to construct a visual distillation experimental system so as to observe the filling status of the mash.

[0018] Specifically, the high borosilicate glass distillation apparatus is cylindrical, with a mesh-like barrier at the lower end of the glass tube. The glass tube is 200mm long and 120mm in diameter. This size design ensures structural compactness while accurately simulating the actual distillation characteristics of the mash. The barrier has a diameter of 120mm and a mesh size of 2mm. This configuration effectively prevents mash leakage while ensuring smooth gas penetration from the bottom. The condenser uses a serpentine condenser tube, ensuring both structural compactness and condensation efficiency. In this embodiment, the condenser is 200mm long and 30mm in diameter, with a condensate flow rate of 1L / min.

[0019] Furthermore, it also includes a distillation flask 4, through which the borosilicate glass distillation apparatus 3 and the steam generator device 1 are connected. The distillation flask 4 can collect the condensate generated during the distillation process, thereby improving the accuracy of the experiment by reducing the interference of condensate on the experiment.

[0020] Methods for monitoring the distillation of fermented mash include:

[0021] Step 1: Fill the distillation vessel with the same mash filling method as the actual distillation process. The mash filling method is either uniform filling or filling with steam. Filling with steam means that when steam is generated in the distillation vessel, an appropriate amount of mash is spread to the position where steam is generated. After spreading, no more steam is emitted. Then, the mash is moved to another position where steam is generated and spread until the entire filling process is completed.

[0022] Step 2: Use an infrared thermal imager to monitor the heat changes of the mash sample during distillation. Since the same mash filling method as the actual distillation process was used, the thermal imaging process in the experiment can be compared with the thermal imaging process of the actual distillation, thus achieving comprehensive monitoring of the temperature field of the distillation apparatus.
