Description

Technical Field

[0001] This utility model relates to the field of deer antler blood processing technology, specifically a low-temperature extraction, concentration and drying device for deer antler blood granules. Background Technology

[0002] Deer antler blood granules are a traditional Chinese medicine granule preparation with deer antler blood as the main ingredient. They are mainly used to replenish qi and blood and strengthen muscles and bones. During the production process, deer antler blood granules need to go through raw material processing, ingredient mixing, drying and concentration. The drying and concentration process can remove moisture from the raw materials, while low-temperature extraction can retain amino acids, growth factors and other active substances to the greatest extent.

[0003] The current low-temperature extraction, concentration, and drying process for deer antler blood granules mainly involves first freezing the deer antler blood on a tray, then evacuating the equipment to a vacuum state. Through temperature changes and sublimation, the water in the deer antler blood is converted into water vapor, which is then removed under negative pressure, completing the extraction, concentration, and drying process. Therefore, current low-temperature extraction, concentration, and drying equipment for deer antler blood typically consists of a low-temperature drying chamber, a refrigeration system, a vacuum system, a circulation system, and an electrical control system. The low-temperature drying chamber provides the operating space for the low-temperature drying of the deer antler blood. To improve drying efficiency, batch operations are often used, which generates a large amount of water vapor during the drying process. Current refrigeration equipment typically has only one negative pressure channel in its low-temperature drying chamber, and the inner wall of the chamber heats up slowly. This causes water vapor from materials at a distance to easily adhere to the outer wall of the equipment, condense into beads, and fall back onto the material, resulting in reduced drying efficiency and poor drying effect. Therefore, this project was developed to address these issues through in-depth research. Utility Model Content

Beneficial effects

[0014] This utility model provides a low-temperature extraction, concentration, and drying device for deer antler blood granules. It offers the following advantages: Through multi-system collaborative optimization, this device effectively solves the problem of substandard drying results caused by water droplet condensation during the low-temperature drying process of deer antler blood.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 This utility model provides an implementation scheme: In the current process of cold and low temperature drying of deer antler blood granules, there is usually only one low temperature drying chamber for both freezing and heating operations. Because the temperature rise of the chamber wall of the low temperature drying chamber is slow, the water vapor generated during the low temperature drying and evaporation process of deer antler blood is easy to come into contact with the side wall of the low temperature drying chamber, resulting in water droplets condensing and causing the drying effect to be substandard.

[0027] To address the aforementioned issues, this application discloses a low-temperature extraction, concentration, and drying device for deer antler blood granules. The device primarily comprises three systems supported and integrated by a main frame. First, there is a low-temperature drying chamber system 1, which provides space for the low-temperature drying operation and holds trays containing the deer antler blood. Second, there is a temperature control system 2, which uses silicone oil as a heat transfer medium. The heat exchange section of the temperature control system 2 is located within the low-temperature drying chamber and is used for freezing and heating the deer antler blood. Finally, there is a vacuum system 3, connected to the low-temperature drying chamber. This system uses a vacuum device to create a vacuum within the chamber, allowing the water in the heated deer antler blood to be directly converted into vapor and discharged.

[0028] The low-temperature drying chamber system 1 includes a chamber body 11, which is preferably a rectangular box. A sealing door 12 is hinged to the chamber body 11. A material rack 13 is installed inside the chamber body 11 to place trays. The material rack 13 has a rectangular frame structure and is divided into multiple layers. A guide rail 14 is installed at the bottom of the chamber body 11. The material rack 13 is slidably mounted on the guide rail 14 to facilitate the removal of the material rack 13 for placing and removing trays. A temperature and humidity sensor and a vacuum sensor are installed inside the chamber body 11 to monitor the temperature, humidity and vacuum status inside the chamber body 11. According to the instruction manual Figure 1-6 It is known that the temperature control system 2 includes a temperature control mechanism 21, which is connected to the main body 11 of the compartment. A circulating heat exchanger 22 is installed in the main body 11 of the compartment. The circulating heat exchanger 22 is configured to cooperate with the material rack 13 and is connected to the temperature control mechanism 21. The temperature control mechanism 21 preferably uses silicone oil as the heat exchange medium. The temperature of the silicone oil is controlled by the temperature control mechanism 21. The silicone oil enters the circulating heat exchanger 22 and heat conduction is achieved by the circulating heat exchanger 22 contacting the tray, etc., to achieve freezing and heating of deer antler blood. After the silicone oil is heated, it returns to the temperature control mechanism 21 to control the temperature again. According to the instruction manual Figure 1-6 It is known that the vacuum system 3 includes a vacuum machine 31, which is located next to the main body 11 of the chamber. The main body 11 of the chamber is provided with a vacuum interface 15. In order to improve the working efficiency of the vacuum system 3, there are multiple vacuum interfaces 15, which are evenly distributed on the top of the main body 11 and connected to the vacuum machine 31 through a vacuum tube 32. An overall control mechanism 33 is provided on the vacuum interface 15 to detachably connect the vacuum tube 32 and the vacuum interface 15.

[0029] According to the instruction manual Figure 1-6 Specifically, the overall control mechanism 33 includes a flow guide housing 331, which has multiple taps 332 connected to multiple vacuum ports 15. The flow guide housing 331 also has a main connector 333, which is a quick-release connector that is quickly connected to the interface at the head of the vacuum tube 32. When the vacuum machine 31 is working, it draws air from the flow guide housing 331 and the main body 11 of the chamber through the vacuum tube 32. The multiple vacuum ports 15 and multiple taps 332 make the distribution of the extraction points more uniform. Furthermore, one-way pressure valves 334 are also provided on the multiple taps 332 to ensure that air can only pass through in one direction and to prevent condensed water droplets from falling back into the chamber. The guide shell 331 can preferably be a conical shell. A drain port 335 is provided at the bottom of the guide shell 331, and the inner end of the tap 332 is higher than the inner bottom surface of the guide shell 331. If condensation occurs, the water will flow to the edge of the conical shell and fall into the bottom of the guide shell 331. The water can then be drained through the drain port 335, thus ensuring that no droplets fall back into the chamber.

[0030] According to the instruction manual Figure 1-6 It is known that the temperature control mechanism 21 includes a refrigeration structure 211, a circulation structure 212 and a heating structure 213. The circulation structure 212 consists of a circulation pump and a storage tank. The circulation pump is connected to the storage tank, which stores silicone oil. The silicone oil is drawn out by the circulation pump and exchanged with the refrigeration structure 211 or the heating structure 213 for heat exchange. Then it is introduced into the circulation heat exchanger 22 to achieve heat exchange with the deer antler blood. The silicone oil after heat exchange is returned to the storage tank. The refrigeration structure 211 is preferably composed of a compressor, a condenser, an expansion valve, an evaporator, and auxiliary parts. The pipeline through which the circulating pump draws silicone oil reduces the temperature of the silicone oil through the heat exchange of the refrigeration structure 211. The heating structure 213 is preferably composed of an electric heater and a plate heat exchanger. The pipeline for the circulating pump to extract silicone oil passes through the plate heat exchanger and then enters the main body 11 of the compartment.

[0031] According to the instruction manual Figure 1-6 It is known that the above-mentioned circulating heat exchanger 22 includes a circulating inlet 221 and a circulating outlet 222. The circulating inlet 221 and the circulating outlet 222 are provided on the main body 11 of the chamber. The circulating inlet 221 and the circulating outlet 222 are respectively connected to the circulating pump and the storage tank. A pair of guide pipes 223 are extended and connected to the inner side of the circulating inlet 221 and the circulating outlet 222. A circulating pipeline 224 is provided on the material rack 13. A pair of sleeve grooves 225 are provided on the circulating pipeline 224 corresponding to the pair of guide pipes 223 and are fitted outside the pair of guide pipes 223. A sealing piston 226 is provided at the end of the guide pipe and is press-fitted with the sleeve groove 225 to maintain a seal. The circulating pipeline 224 should be provided with a branch pipeline at the position of the tray to realize precise heat exchange of the tray.

[0032] In most cases, due to the negative pressure, steam will be quickly discharged from the chamber. However, in order to improve the efficiency of freeze drying, current freeze dryers often use a dense arrangement of trays. As a result, the moisture in the material on the bottom trays is reduced due to the long steam travel path and the steam being easily blocked by the upper trays and the frame. This leads to a decrease in temperature and condensation at the bottom of some upper trays, resulting in poor drying effect of the bottom material. Therefore, in Embodiment 2 of this application, the material rack 13 is improved as follows: the material rack 13 includes a main support, a circulation pipe 224 is embedded in the main support, and tray racks are provided on both sides of the main support. The number of tray racks is divided into multiple, and the tray racks are staggered from top to bottom. The branch pipes of the circulation pipe 224 extend to the bottom of the tray racks, and the trays are placed on the tray racks and are in close contact.

[0033] The operating procedure for this equipment is as follows: First, pre-treatment is performed, and the refrigeration system is activated to lower the silicone oil temperature to -40℃ for pre-cooling for 1 hour. Then, the material rack 13 and guide rail 14 are opened, and the trays containing deer antler blood are placed layer by layer into the staggered slots of the tray rack, ensuring that the bottom of the trays is in close contact with the heat-conducting silicone pads of the circulation pipe 224. After loading, the material rack 13 is pushed along the guide rail 14 into the chamber and locked. In the freeze-drying stage, the refrigeration system is activated to freeze the material through the circulating heat exchanger 22, maintaining a chamber vacuum of ≤20Pa for 2-4 hours until the material is completely frozen. The temperature control mechanism 21 is switched to heating mode, and the silicone oil temperature rises to 30-40℃, allowing for uniform heating of the material through the circulation pipe 224. Meanwhile, the vacuum system 3 continuously pumps air, and the vacuum interface 15 pumps air evenly at multiple points to ensure a uniform pressure gradient in the chamber. The steam rises rapidly along the staggered channels of the tray rack, avoiding condensation problems caused by excessive travel distance. Entering the desorption drying stage, the silicone oil temperature is further increased to 50°C, and heating is continued for 1-2 hours to completely remove the bound water in the material. After drying, the vacuum pump is turned off, and dry nitrogen is slowly introduced until the chamber returns to normal pressure. The sealed door 12 is opened to remove the dried deer antler blood granules. Finally, the equipment is cleaned. The inner wall of the chamber and the circulating heat exchanger 22 are wiped with alcohol to remove residues, and purified water is connected to the drain outlet to rinse the guide shell 331 to ensure no material residue. The entire operation takes about 8-10 hours, and the parameters are automatically monitored and adjusted by the main control system throughout the process.

[0034] This equipment utilizes a multi-point uniform vacuum system 3 to create a three-dimensional vacuum network within the chamber, improving the uniformity of vacuum distribution and preventing steam condensation caused by localized pressure fluctuations. The conical structure of the guide shell 331, combined with the bottom drain port 335, quickly discharges condensed water droplets. The one-way pressure valve 334 further eliminates water droplet backflow. The staggered design of the material racks 13 creates multi-path steam channels, shortening the steam travel distance. Combined with uniform vacuum extraction, this ensures more thorough steam discharge and improves the drying efficiency of the bottom layer materials. The temperature control system 2 employs a silicone oil dual-circulation design, allowing for smooth switching between cooling and heating. Precise temperature and humidity monitoring achieves a temperature control accuracy of ±0.5℃, ensuring a uniform and stable drying process. The overall design, through optimized steam discharge paths and uniform negative pressure extraction, significantly improves the drying effect of deer antler blood granules. Simultaneously, the equipment's ease of operation and safety are greatly enhanced, demonstrating significant technical advantages and practical application value.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
