Description

Technical Field

[0001] This utility model relates to the field of liquid nitrogen production, specifically to a filling device for liquid nitrogen production. Background Technology

[0002] Liquid nitrogen can be used in devices that add liquid nitrogen into beverage containers to remove air and increase internal pressure. Therefore, a liquid nitrogen filling device is required during filling. Chinese patent discloses a filling device for liquid nitrogen production (Authorization Announcement No. CN 221035222). This patented technology, through the coordinated design of the flow rate control component and the dispensing nozzle, can control and adjust the liquid nitrogen dispensing volume according to different beverage containers. By rotating and adjusting the rotating plate, the flow rate orifice can be aligned with the dispensing tube to control the flow rate during different liquid nitrogen dispensing operations. The coordinated design of the spring-loaded component, adjusting component, and abutment component enables low-cost and convenient individual dispensing of liquid nitrogen into beverage containers, avoiding ineffective dispensing and waste during beverage container transport intervals, thus improving efficiency. However, this design, which relies on rotating and adjusting the rotating plate to align the flow rate orifice with the dispensing tube for different liquid nitrogen dispensing operations, lacks a limiting function. When the operator releases the rotating plate, there is a risk of displacement, causing changes in the flow rate. Therefore, those skilled in the art provide a dispensing device for liquid nitrogen production to solve the problems mentioned in the background art. Utility Model Content
