Description

Technical Field

[0001] This utility model relates to the field of industrial protein processing technology, and in particular to a spray dryer for industrial protein preparation. Background Technology

[0002] The concept of industrial protein mainly refers to proteins extracted, separated, purified, or synthesized from animal, plant, and microbial sources through a series of modern biotechnologies and industrial technologies. These proteins are widely used in pharmaceutical, food, feed, chemical, and biotechnology industries.

[0003] Existing spray dryers may not be able to completely remove moisture from materials during the drying process, especially bound water and internal moisture. This may result in a high final moisture content in the product, which in turn affects the product's stability and shelf life. Utility Model Content

[0004] The purpose of this invention is to provide a spray dryer for industrial protein preparation. This device facilitates the graded drying and processing of industrial proteins, thus solving the problem of inconvenient graded drying and processing of industrial proteins in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spray dryer for industrial protein preparation includes a shell with a cavity inside its upper end. Multiple nozzles are equidistantly arranged at the top of the shell, with their upper ends communicating with the cavity. Multiple grooves are arranged in a ring array on the inner wall of the shell, with heating tubes fixedly connected inside each groove. A collection frame is slidably connected inside the shell. Multiple heat dissipation holes are provided at the upper end of the shell. A cavity is located inside the side wall of the shell, with multiple heating wires fixedly connected in a ring array inside the cavity. Multiple holes are arranged in a ring array on the inner wall of the shell, communicating with the cavity and located above the heating tubes.

[0007] Preferably, a liquid storage tank is fixedly connected to the upper end of the shell, and a feed pipe is fixedly connected through the upper end of the liquid storage tank.

[0008] Preferably, a pressure pump is fixedly connected to the upper end of the liquid storage tank, and the output end of the pressure pump is connected to the inside of the liquid storage tank.

[0009] Preferably, a pipe is connected between the liquid storage tank and the cavity, and a valve is installed inside the pipe.

[0010] Preferably, a plate is fixedly connected to the side wall of the shell, an air pump is fixedly connected to the upper end of the plate, and a connecting pipe is fixedly connected between the output end of the air pump and the cavity.

[0011] Preferably, a handle is fixedly connected to the side wall of the collection frame, and a protective sleeve is fixedly connected to the outside of the handle.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. During the downward flow of protein liquid atomization, an external airflow is introduced into the cavity through an air pump and connecting pipe. The airflow is heated by a heating wire and then ejected through multiple holes, thus performing an initial drying treatment on the atomized protein liquid and evaporating its internal moisture. After the initial drying treatment, the protein liquid flows downward and undergoes a secondary drying treatment through multiple heating tubes. By performing a staged drying treatment on the protein liquid, the efficiency of the protein liquid drying process is improved. At the same time, the staged drying technology can effectively remove moisture while maintaining protein activity, avoiding protein denaturation or inactivation caused by overheating or excessive drying during the drying process.

[0014] 2. After secondary drying, the protein liquid is formed into powder. The protein powder falls into the collection frame, where it is collected and processed. By pulling the handle, the collection frame can be pulled out from the shell to process the protein powder inside, thus facilitating centralized collection and processing of the protein powder.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3A spray dryer for industrial protein preparation includes a shell 1, with a cavity 6 located inside the upper end of the shell 1. Multiple nozzles 7 are equidistantly arranged at the top of the shell 1, with their upper ends communicating with the cavity 6. Multiple grooves 14 are arranged in a ring array on the inner wall of the shell 1, with heating tubes 15 fixedly connected inside each groove 14. A collection frame 17 is slidably connected inside the shell 1. Multiple heat dissipation holes 16 are located at the upper end of the shell 1. A cavity 11 is located inside the side wall of the shell 1, with multiple heating wires 12 arranged in a ring array fixedly connected inside the cavity 11. Multiple holes 13 are arranged in a ring array on the inner wall of the shell 1, communicating with the cavity 11 and located above the heating tubes 15. A stream of liquid flows inside the cavity 6. The protein liquid is atomized and sprayed into the housing 1 through the nozzle 7. As the protein liquid atomizes and flows downward, airflow flows inside the cavity 11. The airflow is heated by the heating wire 12 and then sprayed out through multiple holes 13, thereby drying the atomized protein liquid and evaporating its internal moisture. After the initial drying, the protein liquid flows downward and undergoes a second drying process through multiple heating tubes 15. After the second drying, the protein liquid forms a powder and falls into the collection frame 17, where it is collected and processed. At the same time, the moisture evaporated from the drying of the protein liquid flows out from the inside of the housing 1 through multiple heat dissipation holes 16.

[0021] A liquid storage tank 2 is fixedly connected to the upper end of the shell 1, and a feed pipe 3 is fixedly connected through the upper end of the liquid storage tank 2. The protein liquid is input into the liquid storage tank 2 through the feed pipe 3.

[0022] A pressure pump 4 is fixedly connected to the upper end of the liquid storage tank 2. The output end of the pressure pump 4 is connected to the inside of the liquid storage tank 2, and the inside of the liquid storage tank 2 is pressurized by the pressure pump 4.

[0023] A pipe 5 connects the storage tank 2 and the cavity 6. A valve is installed inside the pipe 5. When the pressure pump 4 pressurizes the inside of the storage tank 2, the valve inside the pipe 5 opens, allowing the protein solution to flow through the pipe 5 into the cavity 6.

[0024] A plate 8 is fixedly connected to the side wall of the shell 1. An air pump 9 is fixedly connected to the upper end of the plate 8. A connecting pipe 10 is fixedly connected between the output end of the air pump 9 and the cavity 11. External airflow is input into the cavity 11 through the air pump 9 and the connecting pipe 10.

[0025] A handle 18 is fixedly connected to the side wall of the collection frame 17, and a protective sleeve is fixedly connected to the outside of the handle 18. By pulling the handle 18, the collection frame 17 can be pulled out from the inside of the housing 1, and the protein powder collected inside the collection frame 17 can be processed.

[0026] In this invention, protein solution is fed into storage tank 2 through feed pipe 3, and then pressurized by pressure pump 4, causing the protein solution to flow into cavity 6 through pipe 5. The protein solution is then atomized and sprayed into housing 1 through nozzle 7. During the downward flow of the atomized protein solution, external airflow is input into cavity 11 through air pump 9 and connecting pipe 10. The airflow is heated by heating wire 12 and then sprayed out through multiple holes 13, thereby performing the initial drying treatment on the atomized protein solution and evaporating its internal moisture. After the initial drying treatment, the protein solution flows downward and is then subjected to a secondary drying treatment through multiple heating tubes 15, thereby improving the efficiency of protein solution drying.

[0027] After secondary drying, the protein liquid is formed into powder. The protein powder falls into the collection frame 17, and is then collected and processed by the collection frame 17. By pulling the handle 18, the collection frame 17 can be pulled out from the shell 1, and the protein powder collected inside the collection frame 17 can be processed.
