Description

Vertical type food pulverizer {VERTICAL TYPE FOOD PULVERRIZER}

The present invention relates to a food pulverizer for finely pulverizing cereals, vegetables and the like to a predetermined particle size.

Particularly, according to the present invention, by providing a single assembling means for assembling the crushing means (rotating millstone, rotating steel plate) to be used for general purpose of crushing according to the kind of food, convenience and ease of replacement are guaranteed, The cooling effect of allowing the frictional heat generated in the crushing means to be naturally released to the discharge port and the vertical effect of maximizing the crushing efficiency by further improving the discharge of the crushed food The present invention relates to a food pulverizer.

BACKGROUND ART [0002] Generally, in a home or a restaurant, a food pulverizer is used for finely pulverizing foods such as cereals (beans, rice, sesame seeds, perilla), fruits and vegetables to a predetermined particle size.

These food pulverizers are classified into passive type and vertical type pulverizer depending on the pulverization method.

The electronic horizontal type food crusher is well known as a method of crushing food (grains, vegetables) by horizontally transporting them by a screw feeder.

Such a horizontal type food pulverizer is a method of crushing vegetables, fruit or grains to be supplied while a plurality of screws are engaged, and it has an advantage in that the life of the motor is reduced because the cooling efficiency of the green juice or the grain is low, There is a disadvantage in that reliability is low in that a manufacturing cost is high and a metal component is generated in a process of grinding (juice) by screw (metal) engagement.

The latter vertical type food crusher is a rotary metal mill of a crushing means assembled on a motor shaft of a vertically installed motor or a rotating millstone in which a stone is pressed and fixed, and vegetables or grains etc. inputted through a feeding port provided in the upper lid Is crushed and crushed into a green juice or a predetermined particle.

Such a vertical type food pulverizer has an advantage that no metal component is generated, but has a disadvantage in that pulverization efficiency is lowered at low speed rotation of a driving motor.

Thus, according to the prior art of the applicant of the patent document 1, the rotating millstone by lifting and lowering the motor shaft of the driving motor is raised or lowered according to the type of grain to precisely control the grinding gap with the upper fixed millstone, And to maximize the grinding efficiency of the grain according to the purpose.

The applicant of the present invention has found that, in order to be universally usable without regard to the type of food of the vertical type crusher, the grain inlet of the upper lid and the rotating millstone in which the fixed mill stone as the crushing means of the grain, When grinding fruits and the like, it is used by replacing the upper lid and the rotating steel plate in which the vegetable input port is formed.

In the vertical type food crusher, as described above, the metal steel plate or the rotating millstone is used in place of the crushing of vegetable, fruit, or grain. In the past, the metal plate or the supporting member of the rotating millstone has been replaced So that it is difficult to carry out the replacement work depending on the use of the rotating millstone or the rotating steel plate in accordance with the kind of food, and there is a disadvantage that it is damaged in the replacement process.

Further, in the conventional vertical type food pulverizer, since the heat of frictional heat generated from the fixed millstone and the rotating millstone and the discharge of the crushed grains are not smoothly provided at the time of crushing the grain, the pulverization efficiency is lowered, It has been pointed out as a factor to shorten motor life.

As described in Patent Document 3, a technique of discharging heat generated from a driving motor by sucking outside air while driving a motor is disclosed in Patent Document 3. However, in the case of crushing hard grains, the grain fed between the fixed millstone and the rotating millstone is crushed, There is a disadvantage that the lifetime due to the overheating of the driving motor is shortened because the discharge efficiency is decreased and the rotating load of the driving motor is left as it is.

Also, the rotating steel sheet used for grinding fruits and vegetables has a disadvantage in that the discharge efficiency is lowered because the particles of crushed vegetables or fruits, which are sandwiched by the crushed blade projections protruding from the steel plate body, are simply discharged depending on the centrifugal force.
