Description

Food Processing Equipment {FOOD PROCESSOR}

The present invention relates to a food processing device such as a stock solution or a chopping device using a screw, and more particularly, to a food processing device configured to be assembled to the intended design height of the screw at all times.

As a food processing apparatus using a screw for food processing, a stock solution, a compaction apparatus, and the like are known.

In particular, the stock solution includes a motor-installed main body, a container drum, a mandrel, a screw and a lid. A container drum is assembled to the upper part of the main body, a mandrel is disposed inside the container drum, a screw is disposed inside the mandrel, and a lid is assembled to the upper part of the container drum.

The screw has a rotating shaft, the upper portion of the rotating shaft of the screw is supported by the rotary shaft groove of the lid and the lower portion of the screw rotating shaft is coupled to the shaft of the motor through a waterproof packing installed on the bottom surface of the container drum. At this time, the rotating shaft of the screw has a vertical insertion hole of a predetermined depth at the bottom and the shaft has an insertion portion of a cross-sectional shape, such as a square or hexagon inserted into the insertion hole. Since the insertion hole has a cross-sectional shape such as a square or a hexagon corresponding to the cross-sectional shape of the insertion part, when the insertion part is inserted into the insertion hole, the movement in the rotational direction between the rotation axis of the screw and the shaft of the motor may be restricted.

The shaft of the motor has a jaw in the lower part of the insert, which is in contact with the lower end of the rotating shaft of the screw. And with the jaw, the insertion hole depth of the rotating shaft into which the insertion portion of the shaft is to correspond to the design height of the screw, the end of the shaft can be implemented to contact the top wall of the insertion hole of the rotating shaft.

In the conventional stock solution, the drum is formed in a wide top and a narrow bottom, and the screw is formed in a substantially spherical shape at the center thereof. In addition, at a specific position, the outer surface of the screw is designed to be adjacent (0.5 mm to 2 mm, assembly tolerance, etc.) so as not to contact the inner surface of the mandrel. In certain locations, such as the above, the outer surface of the screw and the inner surface of the net drum have a constant correlation, and therefore, the screw has an installation height of the screw optimized for juice rate, that is, a design height. In addition, it is required that the lower face of the screw be installed so close that it does not contact the bottom face of the drum and the bottom face of the container drum.

However, the conventional undiluted solution is an error generated during the injection molding process of the main body made of plastic, a motor manufacturing error during the manufacturing process of the motor, processing errors occurring during the process of forming the jaw of the shaft, and an assembly generated when the motor is assembled to the main body. Due to the error, the shaft may protrude less or more relative to the top of the body. This causes the height of the screw coupled to the shaft by the rotating shaft to deviate significantly from the design height.

If the shaft protrudes lower than intended and the screw is installed below the design height in the stock solution, the bottom face of the screw will come into contact with the bottom face of the vessel drum and / or the drum and at the same time a portion of the outer face of the screw will It comes into contact with the inner surface of the wire, causing noise and wear of the screw or the drum.

Conversely, when the shaft protrudes higher than intended and the screw is installed beyond the design height in the stock solution, the separation space between the screw and the drum and / or drum is enlarged. The enlargement of this space reduces the juice rate and the quality of the stock solution. In addition, the enlargement of the separation space may cause a problem that the ground and juice is introduced into the lower rotary shaft to leak the residue and juice through the packing and the rotary shaft.

This problem is the same as that of the undiluted solution, but instead of excluding the configuration of the mandrel, the same situation is shown in the compactor (Republic of Korea Utility Model Registration No. 20-2011-0001138) consisting of a drum container having only a waste outlet. to be.

Accordingly, the present invention has been proposed to solve the problems of the prior art, and to provide a food factory configured to ensure that the screw is always maintained at the intended design height regardless of the height of the shaft protruding from the top of the body.

The food processing plant is preferably a stock solution that uses a screw and a mandrel together in food processing, but it is noted that it may be another food processing apparatus such as a chopper device using only a screw.

According to one embodiment, the shaft support member includes a shaft through hole allowing the passage of the shaft, the shaft through hole has a diameter larger than the diameter of the shaft and less than the diameter of the outer diameter of the lower end of the rotating shaft.

According to one embodiment, the shaft support member is provided with a guide protrusion for guiding the rotating shaft rotatably while the surface contact with the outer peripheral surface of the rotating shaft.

According to one embodiment, the shaft support member is provided with a guide recess formed on the lower surface to be held on a portion of the upper end of the body.

According to one embodiment, the insertion hole has a depth to accommodate the protrusion error range of the shaft.

According to the embodiments of the present invention, since the shaft supporting member supports the lower surface of the rotating shaft of the screw in a state in which the shaft supporting member is integrally formed on the lower surface of the container drum without assembly error, the motor installed in the main body is out of position and the shaft is lowered. Or, even if protruding high, the screw can be held at the intended design height. In addition, the outer circumferential surface of the lower portion of the screw rotation shaft is rotatably supported by the guide protrusion of the shaft support member, thereby guiding the lower end of the rotation shaft to a fixed position and preventing shaking of the lower end of the rotation shaft. In addition, a guide recess is formed on the lower surface of the shaft support member so as to fit part of the main body, in particular, the shaft protector, which guides the shaft of the container drum when installing the container drum on the main body. The center guides exactly to the center of the axis of the main body.When the container drum is shaken by screwing or the container drum is shaken by external force, the inner side of the guide recess is in contact with the outer side of the shaft protector. Shake of the drum) can be suppressed.
