Description

Technical Field

[0001] The utility model relates to the technical field of soy sauce koji making, in particular to a raw material mixing mechanism for soy sauce koji making. Background Art

[0002] Soy sauce is a traditional condiment with good flavor. In the process of soy sauce processing, koji making is an indispensable part, which directly determines the taste and quality of soy sauce. The koji making process of soy sauce includes raw material cleaning, steaming, inoculation, etc. In the inoculation stage, the steamed soybeans and wheat need to be mixed in a certain proportion, and in this process, stirring equipment is needed to mix multiple raw materials.

[0003] The utility model patent with the authorization announcement number CN214635717U discloses a soy sauce raw material turning and stirring device, which includes a stirring tank, a stirring shaft and a turning shaft. The top of the stirring tank is provided with a cover plate, and a rotary drive device is provided on the cover plate. The stirring shaft is arranged at the bottom of the rotary drive device and extends downward into the stirring tank. The bottom of the stirring tank is provided with a hopper, and a discharge pipe extending downward is concentrically provided at the bottom of the hopper. The turning shaft is arranged at the bottom of the stirring shaft and extends downward into the discharge pipe. The turning shaft is provided with a spiral blade. The upper wheat and soybean meal are mixed by the stirring shaft, and the discharge pipe and the wheat and soybean meal above it are turned up by the spiral blade to avoid being stranded at the bottom and unable to participate in the mixing, thereby improving the mixing uniformity of wheat and soybean meal. When discharging, the stirring shaft drives the spiral blade to reverse, thereby avoiding the problem of wheat and soybean meal being blocked in the discharge pipe, and ensuring the smoothness of discharging.

[0004] Although the soy sauce raw material turning stirring device avoids the problem of wheat and soybean meal being blocked in the discharge pipe, its performance still needs to be improved in practical applications. Especially when mixing multiple raw materials, only relying on the stirring shaft and stirring blades for stirring, when there are more raw materials piled up in the device, its stirring efficiency is significantly reduced. This results in a longer time to achieve uniform mixing of the raw materials, affecting production efficiency. In view of this, we propose a raw material mixing mechanism for soy sauce koji making.
