The invention relates to a method for grinding grains, as well as to a device for implementing such a method. According to this method, the grains are humidified with a liquid, and compression and shear forces are applied to the grains with a first pair of rollers (4), so that the grain core internal structure (endosperm) is modified and the grain skin undergoes little or no damage. The grains are then transferred to another pair of rollers (5) having a ribbed surface for grinding. This is followed by grinding by another pairs of rollers (6) and/or sieving of the ground products, so that the final product is substantially in the form of flour. The inventive method is a low grinding method.

The invention is directed to a method for producing wheat flour from newly harvested wheat grain. The grain direct from harvest is treated with moisture to increase the moisture content of the endosperms to a level at least about 4 to 5 wt-% greater than the original level, thereby producing hydrated wheat grain. The hydrated wheat grain is then rapidly dried to a moisture content approximating the original level of the newly harvested wheat grain to produce grain that can be efficiently milled. The milling of the treated grain produces a wheat flour that is more acceptable and desirable for baking than that produced from newly harvested wheat that is not processed according to the invention. The rapid conversion of grain from the newly harvested state to a more millable state is shown by an increase in the capacity of the milled flour to rapidly hydrate. Newly harvested grain normally increases its hydration capacity over the first two to three months after its harvest. The method of the present invention permits elimination of this aging process yet produces a flour having desirable baking characteristics.

A grain treatment system (10) incorporating a steam vessel (12) and centrally disposed, grain diverting steam sparger unit (90) for facilitating the flow of homogeneous plugs of grain therearound. The system incorporates a discharge unit (18) having garner valves (75, 77) and/or flow restrictors for facilitating the anti-coring grain flow through the steam vessel (12) with side and corner draw-off therein and the even percolation of steam upwardly therethrough for uniformly heating and moisturizing the grain. A vapor generator (15) is used for providing a heating medium comprising a mixture of condensible and non-condensible gases introduced into the grain through the centrally disposed steam sparger (90). In this manner, homogeneous plugs of grain are uniformly passed through and discharged from the grain treatment system permitting controlled heating and moisturizing of grain and substantially eliminating of coring, grain clingage, static sludge build-up and associated grain treatment problems prevalent in the many prior art systems.

A method and an apparatus for skinning and cutting wet grain has a hopper 10 supplying wet, cooked grain via a feed channel 11 to a hopper 9. The hopper 9 is connected to feed grain to one end of a perforated cylinder 1. Located within the cylinder is a shaft 3 rotatable by a motor 5, the motor being controlled by a variable speed device 7. The shaft 3 carries a plurality of axially spaced rectangular knives 4, adjacent knives being oriented at approximately 90° to one another. In use wet grain entering the cylinder is bruised and the skins of the grain are weakened and removed to fall through the cylinder perforations, and the thus skinned grain is subsequently cut by the knives until of such a size that the grain passes through the cylinder perforations 2. The skins and grain are sorted by blowing and the cut grain is dried for subsequent use.

An apparatus is provided for the treatment and separation of particulate materials such as oil seeds or grains in which the material to be separated is introduced into a vertical chamber (11) near the upper end (12) thereof and allowed to fall through said chamber, contacting horizontally arranged staves (18) toward a discharge (50) at the lower end of said chamber, while a flow of heated gas circulates counter current to the flow of particulate material, whereby fragments of the particulate material such as hulls and flakes, having a lower terminal velocity, are moved upward with said gas flow and may be removed therefrom in a cyclone separator (78) whereas fragments such as meats of oil seeds, having a higher terminal velocity, fall to the lower end of the chamber and are removed through said discharge.

In an apparatus for humidifying polished rice, a conveyor (8; 50; 204A, 204B) has a tubular housing (7; 49; 203) which defines a predetermined transport path for the polished rice. The conveyor conveys the polished rice, while steering the same, along the transport path. A humidifier (17; 72; 253) is arranged in association with the transport path for adding moisture to the polished rice conveyed along the transport path to humidify the polished rice. A blower (26; 58; 254) is arranged in association with the transport path for causing air to flow therealong. A rice milling system comprises a rice polishing machine (1; 100) and the apparatus (22; 200) connected thereto. The rice polishing machine polishes brown rice to form the polished rice. Polishing of the brown rice to the polished rice raises temperature of the polished rice. The polished rice elevated in temperature is supplied to the housing of the apparatus.
