Abstract

PURPOSE:To simultaneously effect rice hulling operation and separation of the unpolished rice from the smaller grains and permit a temporary storage of such unpolished rice, by providing a small rice grain sieving device above a storage tank and such a structure as to effect a selective supply of the unpolished rice to said sieving device. CONSTITUTION:In cases where unpolished rice after hulling and separation is required to be kept temporarily in a storage tank 1 with a small number of workers without separating smaller grains of rice therefrom, a supply changeover valve 17 is switched to a flowingly downward guide state to the storage tank 1, whereby the unpolished rice after hulling and separation brought up by a hull lifting device 2 is flowed downwards into the storage tank 1 for storage therein through a discharge cylinder 2b of the hull lifting device 2 without passing through a small rice grain sieving device 3. Upon the subsequent separation of the smaller grains from the unpolished rice, the supply changeover valve 17 is switched to the side of an unpolished rice hopper 6 of the small rice grain sieving device 3 to supply the unpolished rice to a small rice grain sieving cylinder 5 through the discharge cylinder 2b and then through the unpolished rice hopper 6, whereby the small rice grains are dropped through the sieving opening of the rotating small rice grain sieving cylinder 5 to discharge the unpolished rice thus obtained by sieving the smaller rice grains to the outside through an unpolished rice exit channel 9 located outside the storage tank.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a storage tank equipped with a milligrade sorting device that stores brown rice after hulling while sorting it.

[Prior art and problems to be solved by the invention] As a milligrade sorting device for sorting millet from brown rice after hulling and sorting, there is a millimeter sorting device that sorts millet while rotating a millimeter sorting cylinder around a horizontal axis;
Alternatively, there are vertical millet sorting machines that sort millet while frying from the bottom to the top, but these conventional machines
All of them were either stand-alone or incorporated into a rice hulling machine.

In this conventional device, since the brown rice after sorting is constantly taken out from the brown rice take-out section of the rice sorting device, a worker is required to weigh and bag the taken out brown rice during operation. A problem with highly efficient rice hulling machines is that the rice hulling work cannot be completed unless a predetermined number of workers are present.

Therefore, the present invention has a special combination of a milligrade sorting device and a storage tank, and temporarily stores brown rice in the reservoir tank before or after millage sorting.
This system attempts to eliminate the drawbacks of conventional equipment by making it possible to perform hulling work without the need for a worker who is in charge of removing brown rice temporarily.

[Means to solve the problem]

A technical means for solving such technical problems of the present invention is to place a millimeter sorting device 3 above a storage tank 1 having a grain frying device 2 attached to the side thereof, and to Device 3

[Function and effect of the invention]

When unhulled and sorted brown rice is to be sorted and grain-sized brown rice is taken out, the supply switching valve 17 is switched to the side of the millet sorting device 3 and the brown rice is supplied to the supply hopper 2a of the grain frying device 2. The brown rice fried in the grain frying bag @2 is supplied from the discharge tube 2b to the millet sorting tube 5, and is subjected to sorting action by the millet sorting tube 5 rotating around the horizontal axis, and is sorted according to the mesh size of the millet sorting tube 5. The small rice falls, and the sized brown rice is sent from the sorting start side to the sorting end side, and is taken out of the machine through the brown rice take-out path 7. Also, the brown rice after hulling and sorting is not sorted into small grains. When the brown rice is temporarily stored in storage tank 1 at If unsorted brown rice stored in the storage tank 1 is to be sorted, the supply switching valve 17 is switched to the millimeter sorting device 3.
When the brown rice is switched to the lower transfer spiral device 19 at the bottom of the storage tank 1 and fed to the lower part of the grain frying device 2, the grain is fried by the grain frying device 2, and is supplied from the discharge pipe 2b to the millet sorting device 3. , the milled rice is sorted and taken out of the machine in the same way as above.Depending on the number of workers, the brown rice can be taken out while sorting the millet at the same time as the hulling operation, or the brown rice can be temporarily removed after the hulling and sorting. By choosing whether to store rice or not, it is possible to select the type of hulling work that suits the number of people.
