Description

Spice grinder {GRINDING MACHINE FOR SPICES}

The present invention relates to a spice grinder that finely grinds spices such as pepper, garlic, ginger, etc., and prevents material deterioration due to frictional heat between parts generated when the ingredients are finely crushed, and It relates to a spice grinder that prevents the occurrence of metal powder by abrasion.

Spices such as pepper, garlic, and ginger are added to add flavor and flavor to various foods. These spices are usually added as a subsidiary material of food, and are rarely used whole, and are generally added to food in the form of chopped or pulverized. In particular, in order to use the spices in large quantities, the spices are mechanically pulverized by connecting to a power means.

As an example of such a spice grinder, it is disclosed and known in Patent Documents 1 and 2 below.

The conventional spice grinder disclosed in Patent Literature 1 below, is installed along the axial direction of the pulverizing bin 20 inside the pulverizing bin 20 to rotate by rotation of the drive shaft 50. Extruded by the screw 40 toward the grinding blades (70,80,90) installed at the front end of the grinding barrel 20, and the grinding blades (70,80,90) are extruded by the screw 40 while rotating relative to each other. The incoming material is crushed and discharged through the outlet at the tip of the pulverizer.

Further, the crushing bin 20 is disposed horizontally with respect to the ground and is detachably coupled to the housing 30 installed on the upper end of the case 10, and the screw 40 provided inside the pulverizing bin 20 is front One end of the pulverizer 20 is fitted and supported in the hole in the center direction of the perforated plate 80 coupled to the front end of the pulverizing container 20, and the opposite end of the rear is fitted and supported in the coupling hole of the connector 31, so that it can rotate horizontally. Is supported. In addition, the screw 40 is rotated by the drive shaft 50 by coaxially coupled to the drive shaft 50 extending from the rear of the housing 30 at the rear end.

However, in the above-described structure, frictional heat is generated when the screw rotates between the screw shaft portion and the inner wall of the hole of the connecting pipe 31 supporting the screw shaft portion, and the material to be pulverized is deteriorated due to the frictional heat.

In addition, since the screw shaft portion is supported by the inner wall of the hole of the connection pipe 31 and rotates, abrasion due to friction occurs on the screw shaft portion or the inner wall of the connection pipe hole, and due to this wear, the screw shaft portion is the inner wall of the hole of the connection pipe 31 It is not supported stably, and there is a problem of causing noise and vibration during rotation operation.

In addition, the screw 40 is mainly made of stainless steel to prevent corrosion, and the inner wall (bush) of the hole (bush) of the connecting pipe 31 supporting the shaft portion of the screw is also made of general steel, so iron powder due to abrasion at the frictional area There was a problem of being mixed into the food material to be crushed due to occurrence.
