Description

Technical Field

[0001] This utility model relates to the technical field of mixing devices for bread production, and in particular to a multi-shaft mixing device for bread production. Background Technology

[0002] In the field of large-scale bread production and processing, mixing devices are core equipment affecting the quality of raw material mixing, production efficiency, and finished product quality. Currently, bread mixing devices on the market generally suffer from numerous technical shortcomings, making it difficult to meet the demands of efficient and high-quality production. Traditional mixing equipment typically employs a single-direction, single-axis mixing structure, where the mixing blades can only move along a fixed trajectory. This design causes raw materials to easily form a fixed flow path within the mixing container, making it difficult for materials near the inner wall, bottom, and corners to be fully stirred. This easily leads to accumulation and mixing dead zones, resulting in uneven mixing and directly affecting the bread's fermentation effect and consistency of taste, causing fluctuations in finished product quality. Furthermore, the single mixing mode is inefficient, requiring a long time to achieve the desired mixing effect. In addition, the lids of existing mixing devices often use bolt-fixed or simple snap-fit ​​connections, making disassembly and assembly cumbersome and requiring tools or multiple people to complete. This not only prolongs the time spent on equipment cleaning, maintenance, and removing raw material residues but also increases the labor intensity of operators. Furthermore, some snap-fit ​​structures lack sufficient stability, and the vibration generated by the high-speed operation of the equipment during mixing can easily cause the lid to loosen or even cause raw material leakage, posing a significant safety hazard. On the other hand, bolt-fixed structures are prone to thread wear after long-term use, further reducing connection stability and affecting production safety and equipment lifespan. Therefore, we propose a multi-shaft mixing device for bread production to solve this problem. Utility Model Content

This facilitates a stable connection between the bucket lid and the mixing bucket, preventing loosening and leakage due to vibration during mixing, and improving operational safety.
