The hollow internal circulation kneading machine mixing blade consists of a kneading machine mixing blade shaft, blade body, blade surface, compensator, and internal circulation channel cavity; The propeller shaft is connected to the propeller blade body, and compensators are set up on both sides of the propeller shaft. An S-shaped flow channel is left in the propeller blade body, and the blade surface is sealed with stainless steel plates, creating an internal circulation chamber. The aforementioned internal circulation chamber is a drying tank with one less circulation system; The above-mentioned internal circulation chamber is connected to the safety channel of the circulation system in the mixing blade shaft; Due to the establishment of an internal circulation chamber and its interconnection with the circulation system holes in the mixing shaft of the kneading machine, temperature control of the mixed collagen material can be carried out, and the friction resistance during mixing can be reduced; Because the sealing of the kneading machine blade surface is wrapped around the outer surface layer of the blade body and can withstand certain working pressure, it makes production and manufacturing reliable; Due to its reasonable configuration, user-friendly application, environmental friendliness, and energy efficiency, it has significant value in terms of usability and marketing promotion. Kneading machines, as a commonly used rubber mixing equipment in contemporary chemical industry, are increasingly replacing outdated production, manufacturing, and processing techniques; Little did they know that different production processes have different regulations on the working conditions of kneading machines, such as temperature control, feeding methods, inner liner materials, and driver output power; Today's invention patent rights have created very good methods for temperature control; The traditional kneading machine uses a U-shaped jacket for heating and cooling, but little do they know that there is uneven heating or cooling in some large and medium-sized kneading machines. It is found that the small total heat transfer area is the reason for this situation. As we all know, the height of the heat efficiency is proportional to the total heat transfer area and heat power. Therefore, based on this basic principle, Enso technical engineers have created and invented this type of hollow blade, which can quickly transfer heat according to the hot and cold substances (water, steam, high-temperature heat-conducting oil) and the raw materials reflected by the hot and cold substances passing through the flow channels on the surface of the blade, achieving the actual effect of rapid heat transfer; After experiencing production and manufacturing report display information in specific customer examples, this method greatly improves heat transfer efficiency, reduces rubber mixing and reaction speed, enhances productivity, and also greatly saves product costs
