Description

Technical Field

[0001] The utility model relates to the technical field of food powder grinding devices, and particularly relates to a multi-stage grinder for producing powdery convenience foods. Background Technique

[0002] Grinders are widely used in the powder grinding of mineral products in the fields of metallurgy, building materials, chemical industry, mining, etc. According to the fineness of the material to be ground and the fineness of the discharged material, grinders can be divided into six types: vertical swing grinders, high-pressure suspension roller grinders, high-pressure micro-powder grinders, straight-through centrifugal grinders, super-pressure trapezoidal grinders, and three-ring medium-speed grinders.

[0003] However, when the existing grinders are in use, they cannot effectively re-grind the materials with unqualified volume after grinding, resulting in the need for manual screening after the materials are discharged, and then pouring them into the grinder again, thus increasing the labor intensity of workers.

[0004] For example, a grinder with multi-stage grinding function disclosed in Chinese Patent Publication No. CN218132156U. The grinder drives a plurality of sets of crushing teeth to rotate through a motor to initially crush the feed. After the materials completed the initial crushing fall onto the material distribution plate, a driving rotation mechanism is set to drive the grinding roller to start rotating. At the same time, the rotation mechanism drives the reciprocating mechanism to move vertically and reciprocally through a cam disk, so that the material distribution plate starts to slide up and down reciprocally, screening the materials completed the initial crushing. The materials meeting the particle size are directly dropped into the collection box, and the materials not meeting the particle size requirements move downward on the surface of the material distribution plate. The materials moving to the grinding roller are ground under the fitting action of the grinding plate and the grinding roller, so as to obtain powders meeting the particle size requirements, achieving the effect of eliminating the need for manual secondary screening.

[0005] The following problems exist in the prior art:

[0006] After the above-mentioned grinding device finishes grinding food, due to the easy overheating of the grinding roller and the grinding plate during the grinding friction process, the temperature of the powder rises sharply, resulting in a decline in the quality or deterioration of the food powder. Content of the Utility Model

[0012] A further improvement of the technical solution of the present utility model lies in that: multiple groups of the annular cooling pipes are arranged in an array with the center of the flour milling disc seat as the base point, and multiple groups of the annular cooling pipes are connected with a condensing pipe. The arrangement of multiple groups of annular cooling pipes in an array is to prevent the temperature of the inner ring annular cooling pipe from rising due to heat conduction and being unable to continuously cool down.
