Description

Technical Field

[0001] The present application relates to the technical field of nutrient preparation tools, and in particular to a circulation mixer. Background Art

[0002] The preparation of formulated foods such as nutritional supplements usually requires a stirring device for uniform mixing. Spiral mixers are widely used in the food industry because they have the functions of stirring, mixing and transporting materials.

[0003] However, the existing spiral mixer, such as patent document CN211837612U, only performs a simple single mixing of the materials and then immediately discharges the materials, which may result in insufficient mixing uniformity and makes it difficult to ensure the product quality of the formula food.

[0004] Therefore, how to increase the discharge uniformity of the spiral mixer has become a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] In order to increase the discharge uniformity of the spiral mixer, the present application provides a circulating mixer.

[0006] A circulating mixer provided to achieve the purpose of the utility model comprises:

[0007] Mixed tanks, jackets and agitators;

[0008] The outer cover of the stirring tank is provided with a jacket, and a preset cavity is provided between the inner wall of the jacket and the outer wall of the stirring tank;

[0009] The agitator comprises a driving device, a stirring shaft and a spiral blade, wherein the driving device is installed outside the jacket, an output end of the driving device is connected to the stirring shaft to drive the stirring shaft to rotate axially, one axial end of the stirring shaft penetrates into the stirring tank, and the spiral blade is fixed around one end of the stirring shaft that penetrates into the stirring tank;

[0010] The stirring tank and the side wall of the jacket are both provided with a feed inlet and a discharge port, and the feed inlet and the discharge port are respectively located on both sides of the axial direction of the spiral blade. The preset cavity and the interior of the stirring tank are connected through the feed inlet and the discharge port on the side wall of the stirring tank, and the discharge port of the jacket is provided with a valve.

[0011] The staff can fill the mixing tank with the materials to be mixed through the jacket feed port and the mixing tank feed port, and the materials fall onto the spiral blades. The operating drive device drives the mixing shaft and the spiral blades fixed on the mixing shaft to rotate. The rotation of the spiral blades can transfer the materials put in through the mixing tank feed port to the mixing tank discharge port and mix the materials. A jacket is provided outside the mixing tank. The primary mixing materials enter the preset cavity from the mixing tank discharge port, and the jacket discharge port valve is closed. The materials will not be discharged from the jacket, but will accumulate in the preset cavity. Rotation and stirring are continuous, and subsequent materials are continuously transported, pushing the primary mixing materials to continuously move and fill the preset cavity, until the primary mixing materials are squeezed into the internal space of the mixing tank from the mixing tank feed port again, fall onto the spiral blades, and are transported and mixed again to obtain secondary mixing materials. The third and fourth mixing materials are analogous. The number of stirring times can be flexibly adjusted according to specific stirring needs. After the mixing is completed, the valve of the jacket discharge port can be opened, and the evenly mixed materials are discharged from the circulation mixer under the action of the spiral blades and gravity, and the evenly mixed materials can be collected at the jacket discharge port.

[0012] Compared with the existing spiral mixers that can only perform single mixing, the present application can flexibly select the number of times the materials are mixed. For materials that are difficult to mix evenly, the present application can improve the uniformity of the output through multiple cycles of mixing, thereby ensuring the product quality of the formula food.
