Description

Technical Field

[0001] The invention relates to a large-angle rotating plate layer structure, belonging to the field of pharmaceutical and food machinery and equipment. Background Art

[0002] The plate structure is the core component of the freeze dryer. It is mainly used to load freeze-dried products and transfer heat and mass to freeze-dried products to achieve the purpose of freeze-drying. It is widely used in the pharmaceutical and food industries. The plate structure of traditional API freeze dryers is mostly lifting or slightly flipping. The plate only realizes the functions of loading materials, heat and mass transfer, and cleaning and drainage. After the API is freeze-dried, it needs to be discharged with the help of an external discharge device. The discharge time is long, the process continuity is poor, and the risk of contamination is high. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a large-angle rotating plate layer structure with compact structure and integrated functions, so as to solve the problems of long discharge time and poor process continuity of traditional API freeze dryers and better ensure the quality of freeze-dried products.

[0004] In order to solve the above technical problems, the technical solution of the present invention is to provide a large-angle rotating plate layer structure, which is characterized in that it includes a temperature compensation plate, a plate layer with a folded edge, a plate layer thermal oil inlet pipe, a plate layer thermal oil outlet pipe, a thermal oil outlet manifold, a thermal oil inlet manifold, a flip driving shaft with an internal flow channel, a fixed support shaft and a reinforcing structural member.

[0005] Preferably, the large-angle rotating plate layer structure is characterized in that a plate layer heat conduction oil inlet pipe and a plate layer heat conduction oil outlet pipe are welded on one side of the plate layer with folded edges, and the plate layers with folded edges are arranged at a certain interval. After the arrangement is completed, the heat conduction oil inlet pipe and the heat conduction oil outlet pipe are welded to the heat conduction oil inlet manifold and the heat conduction oil outlet manifold respectively. The arranged plate layers with folded edges, the heat conduction oil inlet manifold and the heat conduction oil outlet manifold are formed into a whole by reinforcing the structural parts.

[0006] Preferably, the large-angle rotating plate layer structure is characterized in that the parts where the heat transfer oil inlet manifold and the heat transfer oil outlet manifold are welded to the connecting pipe are hollow structures, which can enable the heat transfer fluid to flow from the heat transfer oil inlet manifold through the connecting pipe into the plate layer, and then flow out of the plate layer from another interface and enter the heat transfer oil outlet return pipe. A section of the heat transfer oil inlet and outlet manifold and the heat transfer oil outlet manifold are fully welded to the internal flip driving shaft with a flow channel, which can enable the heat transfer medium to flow along the internal flip driving shaft with a flow channel to the external heat transfer fluid circulation system.

[0007] Preferably, the large-angle rotating plate structure is characterized in that the plate structure assembly after welding is installed in the box container through the door on one side of the box container, and the internal turning driving shaft with flow channel is inserted into and extends out of the shaft hole on the other side of the box container. A dynamic sealing structure is used between the internal turning driving shaft with flow channel and the shaft hole to ensure the sealing of the box container. The fixed support shaft at the other end of the plate structure assembly after welding is supported by a support rod inside the box, so that the entire plate structure assembly can achieve stable two-point support. A large pipe mouth is set at the lower part of the box container, which can be connected to the material collection bin. The rotating power device of the plate structure assembly is installed on the internal turning driving shaft with flow channel that is exposed from the box container, and the large-angle turning of the plate structure assembly is achieved by an external power device.

[0008] Preferably, the method for using a large-angle rotating plate layer is characterized in that the plate layer with folded edges is first moved to a horizontal position, a certain amount of liquid is filled onto the plate layer with folded edges, and then the freeze-drying program is started to sublimate the moisture in the material on the plate layer to obtain a dry powder block, and then the rotary power device is started to flip the plate layer assembly at a large angle along the internal flipping active shaft with a flow channel, and the freeze-dried material is directly flipped and poured out from the plate layer, so that the freeze-dried material directly enters the material collection bin connected to the lower part of the box container, and the freeze-dried material flows to the next process.

[0009] The invention has a compact structure and integrated functions, and can realize the closed turning and unloading of freeze-dried products, completely solving the problems of dust exposure, moisture absorption of freeze-dried products, product pollution by the external environment, large footprint of the discharging equipment and high investment in the whole line equipment, facilitating the large-scale closed manufacturing of raw materials, and better meeting the GMP requirements for drug production.
