Description

Technical Field

[0001] This utility model relates to the field of dough mixer technology, and in particular to a closed-type stainless steel dough mixer for pet food processing. Background Technology

[0002] With the booming development of the pet economy, the pet food market continues to expand, and consumers are increasingly demanding higher quality and safety standards for pet food. As a crucial step in pet food processing, dough mixing directly impacts product quality and production efficiency. Traditional pet food dough mixers present several problems in practical applications. Firstly, their poor sealing leads to dust escaping during mixing, polluting the work environment and potentially causing operators to inhale dust, affecting their health. This also fails to meet the increasingly stringent hygiene standards of the food processing industry. Secondly, their simple mixing structure fails to adequately mix pet food ingredients, making it difficult to ensure uniform dough consistency and consequently affecting the taste and quality of the pet food. Furthermore, traditional dough mixers are inconvenient to clean. After dough mixing, a large amount of material often remains on the inner wall of the machine, which not only wastes raw materials but also increases the difficulty and time of cleaning, reduces production efficiency, and the residual material is prone to bacterial growth, affecting the quality of the next batch of products. Announcement No. CN203492666U discloses a fully stainless steel enclosed dough mixer, relating to the field of dough mixer technology. It includes a working chamber and a frame. The working chamber includes a front panel, side panels, and a cover. A dough rolling pin is set in the working chamber, and a drive device is installed on the frame. The drive device is connected to one end of the dough rolling pin. The key feature is that the left and right sides of the front panel are bent and fitted to the side panels, and the sides of the front panel and side panels are connected by bolts. Stainless steel tubes are fitted onto the dough rolling pin. Although the above device reduces the existence of gaps and effectively prevents external dust and dirt from entering the working chamber, ensuring a clean and hygienic dough mixing process, the machine still requires manual cleaning after use. The complex stirring mechanism makes the cleaning process quite troublesome, requiring improvement. Utility Model Content
