Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for sieving rice germ from powdered effluent that is separated from rice during rice milling.
[0002]
[Prior art]
As is well known, powdered effluents that are released from rice when it is polished with a rice milling machine are conventionally used for pickles and are mostly discarded. However, this powdered effluent contains not only rice bran but also rice germ that contains a lot of vitamin E and is extremely nutritious, so the rice germ is screened from this powdered effluent. Attempts have been made to use it as a health food.
[0003]
[Problems to be solved by the invention]
However, when the powdered effluent is applied to, for example, a conventional general vibration sieving machine using a vibration motor or the like, there is a problem that the rice germ is hardened and cannot be screened well.
This invention solves such a subject and provides the apparatus which enables easy sieving of rice germ from a powdery discharge by simple operation.
[0004]
[Means for Solving the Problems]
For this purpose, the rice germ sieving apparatus according to the present invention has a crank chamber formed on one side of a rectangular support container having an open upper end, and a sieve container having a large number of small holes formed in the bottom surface. A flange part is supported on the opening edge of the upper end of the support container so as to be detachable and horizontally movable , and a connecting part extending on the crank chamber is extended to the flange part of the sieve container to form the connecting part. A grooved rail is suspended in the crank chamber from the inserted opening, a crank pin of the crank mechanism is slidably contacted in a slide groove of the grooved rail, the crank mechanism is connected to a driving source, and the crank is driven by the driving source. The sieve container is reciprocated in the support container through a mechanism, and an elastic piece that impacts the sieve container by a collision at the time of reciprocation is projected on the outer end surface of the sieve container or the inner end surface of the support container. It is characterized by comprising

A square tubular portion 15 that is integral with the portion is formed. Reference numeral 16 denotes a plate-like grooved rail having a knob portion 17 formed at the upper end and a slide groove 18 extending in the vertical direction on the front surface. Further, 19 is a handle projecting outward from the lid plate 6 so that it can be manually rotated, 20 is a rotating shaft of the handle, 21 is a large gear in the gear box 7 and fixed to the rotating shaft, 22 is a small gear meshing with the large gear, 23 is a crank fixed to the small gear shaft and projecting into the crank chamber, and 24 is a crank pin. Rotate the crankpin. The crank pin 24 is slidably brought into contact with the slide groove 18 by hanging the grooved rail 16 from the insertion port 14 into the crank chamber. For this reason, when the crank pin 24 rotates, the sieve container 8 reciprocates together with the grooved rail 16, and the elastic piece 11 collides with the inner surface of the support container 1 during the reciprocating motion so that the sieve container 8 is impacted. . The reciprocating stroke is set to 51 mm from the difference between the inner method in the longitudinal direction of the support container 1 and the outer diameter in the longitudinal direction of the sieve container 8.

In this sieving device, when the brown rice is passed through a rice mill, the powdered effluent separated from the rice is placed in the sieve container 8, covered with the opening / closing lid 2, and the handle 19 is rotated to support the sieve container 8. By reciprocating left and right within the container 1, the elastic piece 11 collides with the inner surface of the support container 1 and an impact is applied to the sieve container 8. For this reason, the powdered discharge in the sieve container is separated into rice germ and rice cake, and the rice cake passes through the small through holes 9 and is sieved into the support container 1, and only the rice germ is contained in the sieve container 8. Remain in. In order to smoothly perform sieving in this way, by setting the reciprocating stroke of the sieving container 8 to 50 mm or more, the desired acceleration is applied to the powdered discharge in the sieving container. At the same time, the sudden stop due to the impact effectively separates the powdered effluent into rice germ and straw without solidifying into dumplings.
[0009]
In this apparatus, when the knob portion 17 is lifted and the grooved rail 16 is lifted, the linkage with the crank pin 24 is broken, and the sieve container 8 can be easily taken out from the support container 1 when cleaning is required. it can.
