Food grinder

Abstract

The invention discloses a food grinder. A cutter holder system of the grinder comprises a cutter holder and a cutter shaft, wherein the cutter holder is provided with a bearing; the lower end of the cutter shaft is arranged in the bearing, and the upper end of the cutter shaft is provided with a grinding component; a cup body is provided with a material inlet communicated with the outside; a filtering device is sleeved below the grinding component on the cutter shaft; a powder discharging / heat radiating device is sleeved below the filtering device; a powder discharging / heat radiating device is sleeved above the bearing on the cutter shaft; and a position on the side wall of the cutter holder, which corresponds to the powder discharging / heat radiating device, is provided with an outlet communicated with the outside. Food is delivered to the cup body from the material inlet and ground by the grinding component; the grinding degree is controlled by the filtering device; and the ground food is discharged from the food outlet by the powder discharging / heat radiating device. A convective air cooling system is formed on a passage in a whole food treating process so as to rapidly carry heat produced by high-speed friction between the cutter shaft and an oil-containing bearing out of the cup body and realize automatic food treatment started from feeding. The grinder can run continuously without causing thermal protection and powder burning and the service life of the grinder is prolonged.

Description

technical field [0001] The invention relates to the field of food crushing processors, in particular to soybean milk machines, rice paste machines, dry grinders and the like. Background technique [0002] A common household food grinder includes a power system, a cup body, and a knife seat system, and the power system drives the movement of the knife seat system. The knife seat system is provided with an oil bearing, a knife shaft, and a crushing part (dry knife grinder) arranged on the knife shaft. The built-in motor of the power system drives the knife shaft to drive the crushing part (dry knife grinder) to grind food. The disadvantage is that due to the closed system of the cup body and the knife seat, the heat generated by the high-speed friction between the knife shaft of the crushing part (dry grinding knife) and the oil bearing cannot be dissipated, so that the food grinder can only work for a short time with a gap (generally in the within 1 minute), and the food pow...

AI Technical Summary

Problems solved by technology

The disadvantage is that due to the closed system of the cup body and the knife seat, the heat generated by the high-speed friction between the knife shaft of the crushing part (dry grinding knife) and the oil bearing cannot be dissipated, so that the food grinder can only work for a short time with a gap (generally in the within 1 minute), and the food powder near the knife shaft and oil bearing of the crushing part (dry sharpening knife) will also burn at high temperature and produce peculiar smell, destroying its nutritional value; The structure is similar to vacuum. After the food processing is completed, the knife holder assembly needs to be manually removed to take out the food powder, which is inconvenient to operate.

In addition, the effect of food crushing cannot be controlled and selected, and it cannot take care of the tastes of different groups of people.
