Description

Technical Field

[0001] This utility model relates to a drying device for yeast powder production, belonging to the field of yeast powder drying technology. Background Technology

[0002] As living microorganisms, yeast's survival rate and fermentation activity are directly affected by the drying process. Traditional drying methods can damage cells, while spray drying can rapidly dehydrate and lock in activity. The core principle of a spray drying tower is to utilize atomization and rapid heat exchange to complete water evaporation in a very short time, while maximizing the preservation of yeast activity and fermentation capacity.

[0003] Traditional spray drying towers, based on practical experience, still have the following technical problems:

[0004] 1. There is a lack of flexibility in production scale. Traditional spray drying towers typically use a single large tower design with fixed capacity. When it is necessary to reduce output, the entire tower still needs to operate at full capacity, resulting in significant energy waste (hot air, electricity) and high operating costs. Conversely, when it is necessary to expand production, a complete set of equipment must be built, which involves large investments and long development cycles.

[0005] 2. There is a problem that a single point of failure can lead to a complete production stoppage. If the tower itself, the air inlet, the air outlet, or the control system malfunctions, the entire production line must be shut down for maintenance, resulting in serious production losses.

[0006] 3. During the spray drying process, atomized droplets easily adhere to the inner wall of the drying tower, forming accumulations. Eventually, the machine needs to be stopped for manual cleaning, which affects production efficiency and increases labor costs and downtime losses.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] This invention addresses the shortcomings of the prior art by providing a drying device for yeast powder production. It can solve the problems of insufficient production scale flexibility and single-point failure leading to complete production stoppage, as well as the problem of severe material accumulation on the tower wall, requiring frequent shutdowns for cleaning.

[0009] To solve the above technical problems, the present invention adopts the following technical solution:

[0010] A drying device for yeast powder production includes multiple drying towers arranged side by side. The bottom of each drying tower is connected to a horizontally arranged branch pipe via an air inlet pipe, and the top of each drying tower is connected to a horizontally arranged confluence pipe via an air outlet pipe. Both the air inlet and outlet pipes are arranged vertically. A conical ring is installed at the top of the inner cavity of each drying tower. The large-diameter end of the conical ring is slidably connected to the inner wall of the drying tower, and the small-diameter end of the conical ring is the same as the inner diameter of the air outlet pipe. A ring plate is fitted onto the main body of the conical ring and is fixedly connected to it. The ring plate is fixedly connected to the head of an electric telescopic rod.

[0011] Furthermore, one end of the diversion pipe is connected to the outlet of the air intake pump, and the other end of the diversion pipe is sealed.

[0012] Furthermore, one end of the merging pipe is connected to the inlet of the air pump, and the other end of the merging pipe is sealed.

[0013] Furthermore, on / off valves are installed at the connection between the air inlet pipe and the branch pipe, and at the connection between the air outlet pipe and the confluence pipe.

[0014] Furthermore, both the diverter pipe and the merging pipe are provided with multiple flanges on their walls for connection to the on / off valve.

[0015] Furthermore, the bottom of the drying tower is inclined, and a waste discharge port is provided on the side of the bottom.

[0016] Furthermore, the air inlet pipe is installed vertically through the bottom of the drying tower, and the end face of the air outlet of the air inlet pipe is higher than the height of the bottom of the drying tower.

[0017] Furthermore, a horizontally arranged liquid inlet pipe is installed at the bottom of the inner cavity of the drying tower, and an upward-facing nozzle is installed at the outlet of the liquid inlet pipe, with the nozzle located above the air outlet end of the air inlet pipe.

[0018] Furthermore, the top of the drying tower is horizontally positioned, and an electric telescopic rod that is vertically downward is fixedly installed above the top of the tower.

[0019] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0020] This utility model adopts multiple independent drying towers arranged side by side, which are connected in parallel through diversion pipes and merging pipes. Each tower can be started and stopped independently through on / off valves. When demand is low, only the necessary number of towers can be turned on, which significantly reduces energy consumption and operating costs. When there is a need to expand production, new tower modules can be easily added to solve the problem of insufficient flexibility in production scale.

[0021] This utility model adopts a multi-tower parallel structure. When a fault occurs in a certain tower or its related pipeline, it can be isolated by a shut-off valve, while other towers can continue to operate normally, thus solving the problem of a single point of failure causing a complete production stoppage.

[0022] This invention utilizes a retractable conical scraper structure installed at the top of the inner cavity of the tower body. This structure can scrape off materials adhering to the inner wall during operation or short breaks. The scraped-off material falls to the inclined bottom of the tower and is discharged through the discharge port, reducing the downtime and frequency required to clean up accumulated materials.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0027] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0028] like Figure 1 and Figure 2 As shown in the figure, this utility model provides a drying device for yeast powder production, including multiple drying towers 3 arranged side by side. The bottom end of the drying tower 3 is connected to a horizontally arranged diversion pipe 1 through an air inlet pipe 4, and the top end of the drying tower 3 is connected to a horizontally arranged confluence pipe 2 through an air outlet pipe 5. Both the air inlet pipe 4 and the air outlet pipe 5 are arranged in a vertical direction.

[0029] One end of the diversion pipe 1 is connected to the outlet of the air inlet pump 7, and the other end of the diversion pipe 1 is sealed. The air inlet pump 7 is used to deliver hot air into the diversion pipe 1.

[0030] One end of the confluence pipe 2 is connected to the inlet of the outlet pump 8, and the other end of the confluence pipe 2 is sealed. The outlet pump 8 is used to output cold air containing mixed materials.

[0031] On / off valves 6 are installed at the connection between the air inlet pipe 4 and the branch pipe 1, and at the connection between the air outlet pipe 5 and the confluence pipe 2; multiple flanges for connecting to the on / off valves 6 are provided on the pipe walls of the branch pipe 1 and the confluence pipe 2.

[0032] The bottom of the drying tower 3 is inclined, and a waste discharge port 9 is provided on the side of the bottom. The air inlet pipe 4 is installed vertically through the bottom of the drying tower 3, and the end face of the air outlet of the air inlet pipe 4 is higher than the height of the bottom of the drying tower 3.

[0033] The bottom of the inner cavity of the drying tower body 3 is equipped with a horizontally arranged liquid inlet pipe 10, and the outlet of the liquid inlet pipe 10 is equipped with an upwardly arranged nozzle 11, which is located above the air outlet end of the air inlet pipe 4.

[0034] The top of the drying tower 3 is horizontally positioned, and an electric telescopic rod 14, which is vertically downward, is fixedly installed above the top of the tower.

[0035] A conical ring 12 is installed at the top of the inner cavity of the drying tower body 3. The large-diameter end of the conical ring 12 is slidably connected to the inner wall of the drying tower body 3. As the conical ring 12 moves longitudinally, it can scrape off the material adhering to the inner wall of the drying tower body 3. The small-diameter end of the conical ring 12 is the same as the inner diameter of the air outlet pipe 5, which serves to guide the gas flow.

[0036] The conical ring 12 is fitted with a ring plate 13 that is fixedly connected to it. The ring plate 13 is fixedly connected to the head of the electric telescopic rod 14. The electric telescopic rod 14 drives the conical ring 12 to move through the ring plate 13.

[0037] The specific working principle of this utility model is as follows:

[0038] Hot air first enters the diversion pipe 1, and then is diverted to each drying tower 3. At the same time, the yeast liquid is dispersed into uniform microdroplets through each nozzle 11. The microdroplets come into contact with the precisely temperature-controlled hot air in the inner cavity of the drying tower 3, and the surface of the droplets is quickly dehydrated. The dried powder enters the confluence pipe 2 with the air and then enters the gas-solid separation system to efficiently separate the dried yeast powder from the exhaust gas.

[0039] This invention features a retractable conical ring installed at the top of the tower's inner cavity. As the conical ring moves longitudinally, it can automatically scrape off the material adhering to the inner wall of the tower. After scraping, the material is discharged through the discharge port. The conical ring can also serve as a gas guide.

[0040] In this invention, multiple towers are arranged side by side, and the number of towers can be flexibly expanded according to needs. Some towers can be opened or closed flexibly. When demand is low, only the necessary number of towers are operated to save energy and operating costs. It can also reduce the risk of a complete production line shutdown due to a single point of failure, thereby improving the reliability and availability of the overall system.

The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
