Abstract

PURPOSE:To obtain flour prepared by milling only albuminous parts of malts, by air elutriating malts separated into hulls and albumens in a peeling machine with an aspirator, pulverizing the resultant albumens and sieving the pulverized albumens in a sieving machine. CONSTITUTION:An inner cylinder 20 having a polishing material provided on the outer surface and an outer cylinder 18 formed from a punched wire net material are concentrically placed with a given clearance, e.g. several mm, left therebetween to constitute a relatively rotatable peeling machine 10. Malts with hulls are then fed into the peeling machine 10, polished, separate into the hulls and albumens, sent to an aspirator 12, fed to a duct 24 by a conveyor 22 thereof and lead the hulls upward by air sucked in the horizontal direction, discharged and removed through a blower. On the other hand, the albumens are fed to a pulverizer 14 having a pair of dressing rolls 26 rotating at mutually different speeds, pulverized and completely separated from the residual hulls at the same time. The hulls are then finally removed by, e.g. a sieving machine 16 having a screen of about 20mesh, and four of only the albuminous part is separated and fed to a pulverizer for pulverizing the flour into the final particle size.

Description

[Detailed description of the invention] "Giura" ship The present invention relates to an apparatus for milling malt.

Reizangpi 1 When preparing malt for beer brewing, it is done by crushing the malt, but conventionally the malt with the husks is crushed as is, and the crushed husks and milk are mixed together. I was preparing it.

However, recent research has revealed that brewing by removing the husks and pulverizing only the milk part can produce more delicious beer. However, malt, including the husk, is extremely brittle, so when it is crushed in a regular flour mill, not only the milk but also the husk is crushed, making it difficult to separate the two. becomes.

SUMMARY OF THE INVENTION In view of the above-mentioned points, it is an object of the present invention to provide an apparatus that can obtain a product obtained by milling only the husk of malt.

That is, the flour milling device according to the present invention includes a peeling machine for receiving malt with a grain husk and removing the grain from the milk by polishing the malt, and a peeling machine for removing the grain from the milk by polishing the malt. an aspirator for receiving the malt discharged from the peeling machine, blowing off the grain grains contained in the malt that have been made into fine grains by the peeling machine, and wind-selecting the milk part; The present invention is characterized by having a crusher that receives and crushes milk, and a sieve that sieves the crushed milk and separates the husk left in the milk from the milk.

The flour milling device according to the present invention is configured as described above, and can produce malt flour from which the husk portion has been substantially removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described based on embodiments shown in the accompanying drawings.

As described in the above section of the structure of the invention, the flour milling device according to the present invention basically receives malt with grain husks and removes the grain husks from milk by polishing the malt. a peeling machine 10; and an aspirator for receiving the malt discharged from the peeling machine, blowing off the grain grains contained in the malt and finely divided by the peeling machine, and winnowing the milk part. 1
2, a crusher 14 that receives and crushes the wind-selected milk, and a sieve 16 that sieves the crushed milk and separates the husk left in the milk from the milk. has.

The peeling machine 10 can be a conventional polishing machine for rice polishing, and in the illustrated embodiment, the peeling machine 10 is arranged concentrically at a predetermined interval, usually about several millimeters, and is relatively rotatable. It has an outer cylinder 18 and an inner cylinder 20, the inner cylinder has an abrasive material provided on its outer surface, and the outer cylinder is made of a punched wire mesh material. As shown in the figure, a screw is provided on the malt receiving side (right side in the figure) of the inner cylinder 20 of the beer machine, so as to introduce malt with husks into the space between the inner and outer cylinders. It has become.

The husk of the introduced malt is polished by an abrasive material provided on the surface of the relatively rotating inner cylinder, whereby the husk is separated from the milk inside. On this occasion,
A small amount of the breast area is also polished and removed.

Most of the peeled husk and milk pass through the gap and exit from the end, but some of the scraped fine powder is discharged to the outside through the mesh of the outer cylinder and is processed as described below.
The milk from which the husks have been removed is supplied to the aspirator 12 from the malt discharge side (left side in the figure) of the peeling machine. The aspirator 12 includes a substantially horizontal conveyor 22 that receives the malt supplied from the peeling machine at one end and discharges it from the other end to let it fall, and a nearly horizontal conveyor 22 that sucks air into the falling malt in a substantially horizontal direction and crosses the malt to create a winding system. Make a feeding effect. The air is connected to a blower through a duct 24 that leads upward and is exhausted. The malt that comes out of the peeling machine contains a mixture of peeled grain husks and pores, but the grain husks are removed by the air blowing action of the aspirator.

The mill 14 has at least one pair of rolls 26 that crush the malt from an aspirator by passing the malt between them. The rolls use sharpening rolls and rotate at a speed ratio to each other. Although any combination of tooth profiles of the dressing rolls may be used, a so-called dull-to-dull combination produces good results.

Even for grains whose husks were not completely peeled off by the peeling machine, they are almost completely peeled off during roll crushing.

The sieving machine 16 has about 20 meshes of sieving nets (not shown) and ultimately removes the husks not removed by the peeling machine 10. The milk discharged from the screener is sent to a grinder which grinds it to the final particle size for preparation.

The basic configuration of the flour milling apparatus according to the present invention is as described above, and the illustrated embodiment includes a dust remover 28 and a second sieve 30. The dust remover 28 is of a cyclone type, is connected to the duct of the aspirator 12, receives the fine grain husks and fine milk removed from the malt (the milk part) in the aspirator, and collects the fine and lightweight crushed grain husks. is discharged from the upper outlet. The second sieving machine 30 receives the fine milk and grain husks discharged from the lower outlet of the dust remover 28 and the mesh of the outer cylinder 18 of the peeling machine, and sieves them into about 44 meshes. . This removes the husk and sends the milk to the final grinder, similar to that of the first screener 16.

As a result of milling 200 kg of malt with husks using the above-mentioned apparatus, the husks were separated at a ratio of 13.75% and the malt content available for preparation was 86.25%.

The number of rotations of the peeling machine, the number of abrasives in the inner cylinder, and the number of the outer cylinder need to be changed as appropriate depending on the properties of the malt used. Further, the rotational speed of the rolls of the crusher and the mesh size of the sieve can be changed as necessary.
