Technical field

The present invention relates to rice-washing device (with rice washing portion or rice washing part synonym), apparatus for making bran-free rice (with exempting to wash in a pan the treating apparatus synonym) or the clean rice manufacturing equipment of being furnished with this rice-washing device, and will be fed to the spreading out device that the cereal on the face shakeouts of accepting of accepting parts, wherein rice-washing device is used for making the preliminary treatment that needn't wash rice (with the rice washing synonym) before cooking rice over a slow fire, add the what is called " clean rice (with exempting from naughtyization processing rice or processing Mi Tongyi) " that water can cook rice over a slow fire and have good keeping qualities.

Background technology

With usual method to highed milled rice (with rice material or raw material rice synonym) when washing, the inside that water is immersed in highed milled rice is risen its water content, is easy to mouldyly or corrupt, thereby can not obtain clean rice by the mode the same with handling common highed milled rice.On the other hand, when the highed milled rice that once water content was very high owing to wash is carried out drying, because the stratum granulosum of highed milled rice has when suction the character that expands, shrink during in drying (with reference to special fair 3-36496 communique etc.), so when dry, only have the top layer of highed milled rice sharply to shrink, produce tension force on the top layer and also chap.The highed milled rice that be full of cracks is arranged immerses excessive water thereby non-homogeneous expansion is even from be full of cracks when cooking rice over a slow fire, starch granules is dissolved out in large quantities from be full of cracks, becomes the rice that mouthfeel extreme difference, taste degenerate, and this is well-known.

In the fair 7-106321 communique of spy, put down in writing a kind of apparatus for making bran-free rice, when the pressure-bearing type rice washing portion injection rice washing water (with wash water or rice washing water synonym) of being furnished with mixing drum and agitating roller is washed rice, the dehydration portion supplying washing water of the rice of washing in a pan to washing on one side, on one side washing dehydration.

But, in this apparatus for making bran-free rice, exist because rice washing water and washings both need, so have to use the problem of a large amount of water.Use a large amount of water can increase the expense of running water undoubtedly, if discharge a large amount of sewage (rice washing juice (with washing juice or washing a meter juice synonym)), then obligatedly prevent that according to public hazards regulations are equipped with large-scale high price water purifying equipment, this is a very big problem in the grain industry.

Open in the flat 11-42056 communique the spy, put down in writing a kind of clean rice device, while it is furnished with the highed milled rice that utilizes feed screw below to carry to have added wash water, utilizes reverse conveyor screw to make highed milled rice turn back to the top to stir meter vertical pearling device from the bottom discharge that husk rice is come out, will be handled then.

Yet, in this clean rice device, exist following problem wash water to flow down from the top down, simultaneously carry rice from the top down along the direction identical with wash water, so that wash rice, because the rice of washing is discharged from the bottom, use the water of cleaning in the initial period of washing meter step (position, top), but use the water of dirt to the last fine finishining stage (lower portion) of washing meter step, even in next step dehydration, carry out high efficiency dehydration, aleuron (ア リ ウ ロ Application) residue (rice washing juice) still can be attached to not coming off on the rice, makes the taste variation.

In clean rice device (wet type clean rice device), for example is furnished with rice washing part, the rice material (highed milled rice) that is fed in the rice washing part is stirred and wash rice with rice washing water, form aleuron residue (containing the high semi-liquid-like mixture of viscosity that constitutes as the grease of the undermost aleurone of the chaff skin of brown rice or protein or sugar) and wait and be removed thing and dissociate away and be dissolved in state the rice washing water from rice material is surperficial.And this apparatus for making bran-free rice is furnished with dehydration portion, will be supplied to dehydration portion to dewater through washing a meter rice material of handling.

And then this apparatus for making bran-free rice is furnished with drying section.On drying section, be provided with dry disk, will be fed to through the rice material that processed is crossed on the dry disk of rotation, on rice material, send warm braw, make the rice material drying.

Thereby apparatus for making bran-free rice exempts from naughtyization processing to the rice material rectangle and produces to handle rice (dried raw material rice in drying section).

Therefore, usually corresponding to the recruitment of the clean rice moisture content of the water content (usually greatly about about 14 weight % to 15 weight %) of rice material preferably within positive 0.5 weight %, and the moisture content of clean rice preferably coexists in the scope of 14 weight % to 15 weight % mutually with the raw material rice.

This be because, when surpassing positive 0.5 weight % corresponding to the recruitment of the clean rice moisture content of the moisture content of rice material, the stolen goods rice washing water (to call " washing a meter juice (with rice washing juice or wash the juice synonym) " in the following text) that contains the aleuron residue in rice washing part when washing meter immerses in the highed milled rice in a large number, and the taste that contains the clean rice of washing meter juice in a large number descends.

And, when the moisture content of clean rice during less than 14 weight %, the top layer part of clean rice is easy to produce be full of cracks, and excessive water immerses from be full of cracks and causes differential expansion when cooking rice over a slow fire, starch granules dissolves outflow in a large number from be full of cracks, forms mouthfeel extreme difference, the bad rice of taste change.

When from water filling port 76A an amount of wash water (pure water) being injected when washing the meter chamber 74 in by feed-tank (omitting among the figure), utilize the raw material rice and the wash waters that 72 pairs on meter roller washes in meter chamber 74 of washing of rotation to stir together, wash a rice processing.Thereby aleuron residue etc. is removed thing and dissociates out from raw material rice surface and be dissolved into the wash water.Therefore, wash water water filling port 76A from the head injects, and is dirty naturally from the top down, and rice is carried and washed to free surface against the direction of wash water from bottom to top.Like this, washing the final stage (washing the top of meter chamber 74) that rice is handled, utilization is washed rice from the water of the cleaning of the head injection of rice washing part 12 and is handled, and washing the contaminated water in meter treatment step of washing that uses in meter initial period (washing the bottom of meter chamber 74) of handling in aforementioned final stage, thereby can effectively wash rice and handle.Like this, washing the dirty water of initial period use that rice is handled, along with washing the carrying out that rice is handled, use the water of cleaning gradually, at the water of the terminal stage use cleaning of washing the rice processing, thereby, needn't inject new washings, available a spot of water produces the good clean rice of taste.

In addition, because the dehydration liquid of discharging from carrier pipe 162 by the raw material rice is dewatered in the dehydration portion 14, be attached to the water on the raw material rice in the final stage (washing the top of meter chamber 74) of washing the rice processing, relatively cleaner so (clean water), even this dehydration liquid uses as wash water and also can not make the composition that immerses chaff in the raw material rice washing initial period (washing the bottom of meter chamber 74) that rice handles, the taste of clean rice can not descend fully.Thereby in the apparatus for making bran-free rice 10 according to present embodiment, this dehydration liquid is pumped up water by pump 164, by manage 86 and feed pipe 84 to the bottom water filling of washing meter chamber 74, thereby, can make that to inject the amount of the wash water wash meter chamber 74 from water filling port 76A less, can obtain the further effect of water saving.In addition, different in employing with present embodiment, go out of use and not to washing under meter situation of the structure of chamber water filling by the dehydration liquid that in dehydration portion, raw material rice dehydration is obtained, need be corresponding to the wash water of about 40% weight of raw material rice weight, and in the apparatus for making bran-free rice 10 according to present embodiment, only need be corresponding to the wash water of about 10%～15% weight of the weight of raw material rice.

Wash meter naughty water plate 72B that the raw material rice of handling is rotated and discharge from the lower end of discharge pipe 92, by the lower end that mitron 118 arrives dehydration inner cores 104 of walking of dehydration portion 14 by outlet 52C.And, the wash water (washing juice) through washing the dirt that rice handles from the lower end of drip chamber 90 and a lower end of washing rice tube 52 discharge, outside the apparatus main body 18 of discharging by water-intake pipe 116, drainpipe 128 and the drainage path 182 of dehydration portion 14.

Therefore, washing juice is stoped by the raw material rice of being carried from bottom to top by the screw thread 68 of winnowing, be difficult for flowing to and winnow in the chamber 70, in the present embodiment, because running through to be arranged on, discharge outlet 52B washes rice 52 washes on the 74 formation positions, meter chamber, discharge from this discharge outlet 52B so wash juice, can prevent from that it is trapped in to wash in meter chamber 74.

In addition, so owing to prevented that from the juice of washing that discharge outlet 52B discharges high concentration the composition of washing the chaff the juice from being absorbed by the raw material rice in the initial period of washing the rice processing, the concentration of washing juice reduces, and can improve the taste of clean rice.

In dehydration portion, by the speed rotating centrifugal dehydration tube 100 of dehydration motor 134 with regulation.That is, in speed (for example 1200rpm) rotation of dehydration inner core 104 with regulation, dehydration urceolus 106 is with fixing speed (for example 1000rpm) rotation smaller than the dehydration inner core.Simultaneously, made air blade 156 rotations by the rotation that utilizes dehydration urceolus 106, air-breathing from air entry 120.The tap 106A of the blowing chamber 140 of this air process dehydration inner core 104, blowhole 104A, dewatering station 108, dehydration urceolus 106 arrives in the exterior cover pipeline 102.

The raw material rice that arrives dehydration inner core 104 lower ends supplies to the bottom of dewatering station 108 by handover mouth 142 by centrifugal force.Supply to the raw material rice in the dewatering station 108, while by helical blade 144 centrifugal dehydration of rising, dehydration liquid is discharged from the tap 106A of dehydration urceolus 106.At this moment, attached in the way of wash water in rising to dewatering station 108 on the raw material rice all by centrifugal dehydration.And,, centrifugal dehydration is helped out by being ejected into the dewatering station 108 from above-mentioned air entry 120 inhaled airs.The raw material rice that processed is crossed, only be attached with in its surface under the state of water, discharge by take-off plate 158, delivery board 174 and transport path 178 from the top of dewatering station 108 by centrifugal force and free-falling, supply on the dry disk 204 of drying section 16.

In drying section 16, utilize dry motor 208 with fixing speed (for example 7rpm) Rotary drying disk 204, supply to adjustment plate 252 and the regular plate 254 that raw material rice on the dry disk 204 is prescribed number and spread (shakeouing) equably.The raw material rice that on dry disk 204, shakeouts, flow out to outside the apparatus main body 18 and through air vent 204A, exhaust chamber 218, exhaust outlet 220 and the blast pipe 222 of hothouses 206, dry disk 204 from heater 251 and to brush by warm braw, thereby, make clean rice (with handling Mi Tongyi) by removing the water that adheres to from the teeth outwards fully and carrying out drying.The raw material rice of making clean rice is discharged from discharging conduit 226, and that finishes the raw material rice exempts from naughtyization processing.

Therefore, corresponding to quantity delivered that supplies to the raw material rice on the dry disk 204 and state (state such as water yield of adhering to), adjustment is corresponding to the relative position of the above-below direction of adjusting plate 252 upper surfaces and horizontal direction and adjust the angle of inclination of the side of plate 252 and prescribed direction A opposition side with respect to prescribed direction A, thereby, restriction supplies to the quantity delivered of the raw material rice on the dry disk 204 and state etc., the raw material rice can be shakeout well.

So, supply to raw material rice on the dry disk 204 and can well be shakeout and have certain bed thickness, therefore, can prevent that the uneven drying of raw material rice is even and drying efficiency is low, can obtain the few homogeneous clean rice of moisture change.

And then, because regular plate 254 has elasticity, so regular plate 254 strain one side shakeouts the raw material rice on the dry disk 204 on one side.Thereby, the quantity delivered of the raw material rice on supplying to dry disk 204 and the state etc., the quantity delivered variations of the raw material rice of supplying with on dry disk 204 in the operation of apparatus for making bran-free rice 10 etc. are unrestricted, and the raw material rice can be shakeout into one deck well.

Thereby the raw material rice that supplies on the dry disk 204 can be shakeout into one deck well, and has certain bed thickness, thereby, can obtain few homogeneous clean rices such as one deck moisture variation.

And, when the scope of being stipulated by the bed thickness ratio of ultrasonic sensor 232 detected raw material rice is thick, at least implement one of following two kinds of operations: control panel 50 carries out the decrement treatment that subtend is washed the raw material rice quantity delivered in the rice tube 52 by reducing the revolution of supply motor 56; Or control panel 50 is undertaken the speedup of the rotary speed of dry disk 204 is handled by the revolution that improves dry motor 208.Thereby the bed thickness of raw material rice is thinned to the bed thickness in the prescribed limit, prevents when the adjustment plate 252 by defined amount shakeouts the raw material rice, and the raw material rice is from adjusting overflow on the plate 252, and the bed thickness of the raw material rice after shakeouing can keep constant.

On the other hand, when the scope of being stipulated by the bed thickness ratio of ultrasonic sensor 232 detected raw material rice is thin, at least implement one of following two kinds of operations: control panel 50 passes through to improve the revolution of supply motor 56, carries out the increment processing that subtend is washed the raw material rice quantity delivered in the rice tube 52; Or control panel 50 carries out the deceleration processing to the rotary speed of dry disk 204 by reducing the revolution of dry motor 208.Thereby the bed thickness of the bed thickness thickening of raw material rice in the prescribed limit can prevent the top layer part depression of the raw material rice after adjustment plate 252 by defined amount shakeouts, and the bed thickness of the raw material rice after shakeouing can keep constant.

Therefore, can prevent the inhomogeneous drying of raw material rice, prevent that the quality of clean rice from worsening.

And then, because above-mentioned ultrasonic sensor 232 detects near the bed thickness of the raw material rice adjustment plate 252 and the prescribed direction A opposition side, so as shown in Figure 6, detected at adjustment plate 252 and block upper layer part and form the bed thickness of raw material rice of the position of mountain shape by defined amount.Therefore, detect from adjusting under the situation of bed thickness of raw material rice of position of opposition side that plate 252 leaves prescribed direction A at ultrasonic sensor 232, the bed thickness that skin section may be the raw material rice of convex-concave state can be avoided detecting, the bed thickness of raw material rice can be more stably detected.

In above step, the time of passing through of the each several part of raw material rice is: be approximately 5 seconds in rice washing part 12, be approximately 25 seconds in dehydration portion 14, be approximately 30 seconds in drying section 16, whole process required time is approximately 1 minute.Like this, the time that the raw material rice contacts with water is very short, can produce high-quality clean rice.

Therefore, when shore supports is in apparatus main body 18, be provided with on the arm 28 of pillar 26 by rice washing part 12 (comprise funnel 58, sctew feeder 54 and wash Mi Mada 38), by being rotation rice washing part 12 in center with pillar 26, make rice washing part 12 to mount and dismount with respect to apparatus main body 18.So, only by unclamping clamping bar 34 and being that center rotation rice washing part 12 makes rice washing part 12 break away from from apparatus main body 18 with pillar 26 simultaneously, position (for example washing the lower ending opening of rice tube 52 or the lower end of drip chamber 90 and discharge pipe 92) and dehydration portion 14 that rice washing part 12 is connected with dehydration portion 14 are the state that exposes with rice washing part 12 connecting portions (for example enclosing cover 112 or inner cap 114).Thereby, the separation of rice washing part 12 or dehydration portion 14 and assembling once again become easily (owing to the modular construction of rice washing part 12 or dehydration portion 14, even do not separate rice washing part 12 or dehydration portion 14, also can clear up or wash) rice washing part 12 or dehydration portion 14, thereby the maintenance of apparatus for making bran-free rice 10 (also comprising the separation of rice washing part 12 or dehydration portion 14 and assembling once more except that cleaning or washing) is more easy.

And then, because apparatus main body 18 is coated with and covers 22, enclosing cover 112 and inner cap 114, rice washing part 12 does not have cap covers, be more prone to (possibility of cleaning or washing rice washing part 12 is bigger under the state that does not separate rice washing part 12) so rice washing part 12 separates and assembles once more, the maintenance of apparatus for making bran-free rice 10 is more prone to.

Particularly, under the state that rice washing part 12 comes off from apparatus main body 18, the lower ending opening of washing rice tube 52 exposes.

Thereby rotating shaft 40 (comprise and wash meter roller 72 and the screw thread 68 of winnowing) can easily disassemble from the lower ending opening of washing rice tube 52.Thereby the maintenance (comprising other repairing or replacing outside cleaning or the washing etc.) of washing rice tube 52 inside (comprising supply port 52A and outlet 52C), rotating shaft 40 (comprise and wash meter roller 72 and the screw thread 68 of winnowing) is promptly truly feasible again easily.

Wash the residual rice in the rice tube 52,, utilize the screw thread 68 of winnowing to make its decline and discharge from a lower ending opening of washing rice tube 52 by making rotating shaft 40 opposite direction rotation (preferably under the state that injects water from water filling port 76A, carrying out) along the time with normal rotation.Thereby rotating shaft 40 separates from washing rice tube 52, and residual rice can be discharged outside washing rice tube 52.

In the funnel 58 and cleaning in the sctew feeder 54 or washing etc., can by make water or air etc. in funnel 58, in the sctew feeder 54 and wash in the rice tube 52 by and carry out easily.

And then under the state that rice washing part 12 breaks away from from apparatus main body 18, the lower ending opening of the lower ending opening of drip chamber 90 and discharge pipe 92 exposes.Thereby, can easily clear up or wash from the lower end of drip chamber 90 and the lower end of discharge pipe 92 reaching in the discharge pipe 92 in the drip chamber 90.

On the other hand, under the state that rice washing part 12 breaks away from from apparatus main body 18, the upper end open of the water-intake pipe 116 of dehydration portion 14 and the upper end open of walking mitron 118 are exposed.Thereby, inside easily inner to water-intake pipe 116 and that walk mitron 118, the upper end of can be from the upper end of water-intake pipe 116 and walking mitron 118 is cleared up or is washed, simultaneously, also can easily carry out cleaning in the drainpipe 128 of the lower end of inserting water-intake pipe 116 or washing etc. from the upper end of water-intake pipe 116.

And then under the state that rice washing part 12 breaks away from from apparatus main body 18, inner cap 114 and enclosing cover 112 expose.

Thereby, only by inner cap 114 is broken away from from the upper wall (enclosing cover 112) of apparatus main body 18, can be with inner cap 114, simultaneously also have water-intake pipe 116, walk mitron 118 and the plate 122 of becalming takes off.Thereby, when making that water-intake pipe 116 inside, the cleaning of walking mitron 118 inside and drainpipe 128 inside or washing etc. are more prone to, can be more prone to the cleaning of the plate 122 of becalming or washing etc.In addition, only, can open the scope of the inboard of dehydration inner core 104 by making inner cap 114 break away from (enclosing cover 112) from the upper wall of apparatus main body 18.Thereby, also more easy to cleaning or the washing that (comprises blowhole 104A and transfer mouth 142) in the dehydration inner core 104.

And then under the state that the upper wall that only makes enclosing cover 112 from apparatus main body 18 breaks away from, the integral body of opening port 110 is opened and the inboard scope of exterior cover pipeline 102 is opened.Thereby, also more easy to the cleaning of take-off plate 158, delivery board 174 or washing etc.And, by dehydration inner core 104 is separated, also more easy to the cleaning of (comprise blowhole 104A and transfer mouthful 142) in the dehydration inner core 104 or washing etc., simultaneously, can easily carry out the cleaning of (comprising tap 106A) in helical blade 144 and the dehydration urceolus 106 or washing etc.And then, by dehydration inner core 104 is separated dehydration urceolus 106 is separated, just can more easily clear up or wash (comprising tap 106A) in the dehydration urceolus 106, simultaneously, also can be easily to playing air blade 156, exterior cover pipeline 102 inside and carrier pipe 162 inside are cleared up or washing etc.

And then, by making rice washing part 12 as mentioned above with respect to apparatus main body 18 rotations, rice washing part 12 and the connecting portion of dehydration portion 14 and the connecting portion of dehydration portion 14 and rice washing part 12 are exposed, thereby, even the size of rice washing part 12 and dehydration portion 14 does not leave sufficient surplus, the also maintenance that can suit to rice washing part 12 and dehydration portion 14.Like this, can realize the miniaturization of apparatus for making bran-free rice 10.

And, since wash electric wire 60, the feed back sensor 62 of electric wire 48, the supply motor 56 of Mi Mada 38 distribution 64, supply with the pipe 82 of wash waters and carry the pipe 86 etc. of dehydration liquid to run through the inside of pillar 26 from pump 164 to feed pipe 84 to pipe arrangement 80 from feed-tank, so can prevent electric wire 48, electric wire 60, distribution 64, pipe 82 and manage 86 etc. rice washing part brought obstacle with respect to the rotation of apparatus main body 18.

And then, owing to apparatus main body 18 tegmentums 22, enclosing cover 112 and inner cap 114 cover, so can keep the safety of apparatus for making bran-free rice 10.

And then, owing to wash the lower ending opening of rice tube 52, be installed at rice washing part 12 under the state of apparatus main body 18, by making rotating shaft 40 opposite direction rotation along with normal rotation the time, (preferably under the state that injects water from water filling port 76A, carrying out), the screw thread 68 of winnowing makes to be washed in the rice tube 52 residual rice (raw material rice) and descends and discharge from a lower ending opening of washing rice tube 52, can make residual rice grain pattern cross water-intake pipe 116, drainpipe 128 and drainage path 182 and be discharged to outside the apparatus main body 18.Thereby, even rotating shaft 40 (winnow screw thread 68 and wash meter roller 72) does not separate from washing rice tube 52, residual rice also can be discharged to be washed outside the rice tube 52, thereby, residual rice in will washing rice tube 52 is discharged to be washed when keeping in repair outside the rice tube 52, needn't separate and assembling (comprising disengaging and the fitting operation of rice washing part 12) once more rice washing part 12, can easily keep in repair with respect to apparatus main body 18.

And, under rice washing part 12 is installed in state on the apparatus main body 18, water (water that injects from water filling port 76A) flows to be washed in the rice tube 52 and this water is discharged from a lower ending opening of washing rice tube 52, and, by this water is discharged to outside the apparatus main body 18 by water-intake pipe 116, drainpipe 128 and drainage path 182, can to wash in the rice tube 52, the screw thread 68 and wash meter roller 72 and clear up or wash of winnowing.Thereby, the screw thread 68 or wash meter roller 72 even winnow from washing a rice tube separation, also can to wash in the rice tube 52, the screw thread 68 and wash meter roller 72 and clear up or wash of winnowing, thereby, to wash in the rice tube 52, the screw thread 68 and wash that meter roller 72 is cleared up or during maintenance such as washing of winnowing, needn't carry out the decomposition of rice washing part 12 and assembling (comprising disengaging and the fitting operation of rice washing part 12) once more, maintenance is more prone to respect to apparatus main body 18.

And, be installed at rice washing part 12 under the state of apparatus main body 18, water or air etc. are in funnel 58, in the sctew feeder 54 and wash in the rice tube 52 and pass through, and, water or air etc. are discharged to outside the apparatus main body 18 by water-intake pipe 116, drainpipe 128 and drainage path 184, thereby can clear up or washing etc. the inside of the inside of funnel 58 and sctew feeder 54.Thereby, when the cleaning of funnel inside and sctew feeder 54 inside or washing etc. are keeped in repair, needn't carry out the separation of funnel 58 or sctew feeder 54 and assembling (comprising dismounting and the fitting operation of rice washing part 12 (comprising funnel 58 and sctew feeder 54)) once more, can easily keep in repair funnel 58 and sctew feeder 54 with respect to apparatus main body 18.

And then, as Fig. 3 describes in detail, in rice washing part 12, in the upper side of supply port 52A (the A position of Fig. 3), because helical blade 68A and the gap length of washing between the rice tube 52 (for example about 5mm) make the raw material rice can not produce particle, produce particle so can prevent the raw material rice when screw thread 68 transferring raw material rice are winnowed in utilization.On the other hand, owing to make the raw material rice can not fall at lower side (the B position of Fig. 3) the helical blade 68A of supply port 52A and the gap length of washing between the rice tube 52 (below for example about 1mm), so can prevent that the raw material rice falls from the lower ending opening of washing rice tube 52 when running well, simultaneously, the wash water (washing juice) that in rice washing part 12 (washing in the rice tube 52) the raw material rice is cleaned can be discharged from the lower ending opening of washing rice tube 52.

And then, in the upper side (the A position of Fig. 3) of supply port 52A,, can prevent further when winnowing screw thread 68 transferring raw material rice that the raw material rice from forming particle so utilize owing on rotating shaft 40, form a helical blade 68A.On the other hand, in the lower side (the B position of Fig. 3) of supply port 52A,, can prevent further that the raw material rice falls from the lower ending opening of washing rice tube 52 when running well owing on rotating shaft 40, form two helical blade 68A.

And then, in this apparatus for making bran-free rice 10, after the clean rice manufacturing finishes, utilize the running program of memory in above-mentioned control panel 50 its inside to be cleaned with setting-up time.Inner startup operation of cleaning is, at first, at the dry motor 208 that drives drying section 16 afterwards with Rotary drying disk 204 (heater 216 is not worked), drive the dehydration motor 134 of dehydration portion 14 and carry motor 168 with rotary dehydration inner core 104, dehydration urceolus 106 (comprising take-off plate 158) and delivery board 174, and, when making funnel 164 action by switching valve 186 sealed tubes, 86 sides and open branched pipe 184 sides.Secondly, the rice washing water that comes from feed-tank is injected into a top of washing rice tube 52 from a plurality of water filling port 76A of rice washing part 12, drives at last and washes Mi Mada 36 with counter-rotating rotating shaft 40 (not driving supply motor 56).

By described inner the cleaning, the residual rice in the dehydration portion 14 is transported in the drying section 16, dehydration, and the residual rice in the drying section 16 is discharged from discharging conduit 226, thus the residual rice in the dehydration portion 14 and in the drying section 16 is discharged from discharging conduit 226.And the residual water of dehydration portion 14 is discharged to outside the apparatus main body 18 by branched pipe 184 and drainage path 182 by pump 164.And then, the rice washing water that comes from a plurality of water filling port 76A is to washing rice tube 52 inside, washing meter roller 72 and the screw thread 68 of winnowing cleans and discharge from a lower ending opening of washing rice tube 52, and, the residual rice of washing in the rice tube 52 is swept away by rice washing water, carried from the top down by the screw thread 68 of winnowing of counter-rotating simultaneously, discharge from a lower ending opening of washing rice tube 52, cross water-intake pipe 116, drainpipe 128 and drainage path 182 and be discharged to outside the apparatus main body 18 from washing rice washing water that rice tube 52 lower ending openings discharge and residual rice grain pattern.

And then, clean after the time that has begun through setting internally, carry out inner shut-down operation of cleaning.The shut-down operation that this inside is cleaned is, at first, stopping the washing after the rotation of Mi Mada 38 with the axle 40 that stops the rotation of rice washing part 12, stops to supply with rice washing water to stop the water filling from a plurality of water filling port 76A from feed-tank.Secondly, stop the dehydration motor 134 of dehydration portion 14 and carry motor 168 stopping to dewater inner core 104, dehydration urceolus 106 (comprising take-off plate 158) and delivery board 174, and, pump 164 stopped, simultaneously by switching valve 186 sealing branched pipes 184 and open pipe 86 sides.At last, stop the dry motor 208 of drying section 16 and stop dry disk 204.

Thereby, in apparatus for making bran-free rice, during inside behind above-mentioned apparatus for making bran-free rice EO is cleaned, the inside cleaning operation of rice washing part 12 (wash rice tube 52 inside, winnow screw thread 68 and wash the cleaning operation of meter roller 72 and the discharging operation of residual rice) and the inside cleaning operation of dehydration portion 14 and drying section 16 discharging operation of residual water (residual meter or) can carry out automatically, the inside cleaning operation of rice washing part 12, dehydration portion 14 and drying section 16 can easily carry out.Thereby, can reduce the maintenance frequency (interval of maintenance can be longer) of aforesaid apparatus for making bran-free rice 10.

Below, be used to carry out the step that the adjustment of clean rice moisture content is handled according to Fig. 8 number.

At first, in step 700, drive supply motor 56, wash Mi Mada 38, dehydration motor 134, carry motor 168, dry motor 208, simultaneously, in washing meter chamber 74, supply with wash water from feed-tank (omitting the figure).In step 702,, begin to utilize rice washing part 12, dehydration portion 14 and drying section 16 to carry out the manufacturing of clean rice from funnel 58 base feed rice.In step 704, detect from the moisture content of the raw material rice of funnel supply by the auto moisture meter, simultaneously, detect from the moisture content of the clean rice of discharging conduit 226 discharges by auto moisture meter 256, in the moisture indicating panel of control device 50, represented.In step 706, recruitment corresponding to the moisture content of the clean rice of the moisture content of raw material rice (usually at 14 weight % to about the 15 weight %) remains in the positive 0.5 weight %, simultaneously, when the moisture content of clean rice in the scope of 14 weight % to 15 weight % the time, finish the adjustment of the moisture content of clean rice is handled.

On the other hand, surpass under the situation of positive 0.5 weight % in recruitment corresponding to the moisture content of the clean rice of raw material rice moisture content, or at the moisture content of clean rice not under the situation in the scope of 14 weight % to 15 weight %, in step 708, by 50 pairs of fans of control device, dry motor 208, the intensity of heater 216 and air conditioner is adjusted or they is carried out switching manipulation, thereby, the flow of the warm braw that adjustment is sent to each hothouse 206, the rotary speed of dry disk 204, to the warm braw temperature of hothouse 206 air-supplies or the atmospheric temperature or the humidity of humidity and inflow in apparatus main body 18, thereby, to adjust in the positive 0.5 weight % corresponding to the clean rice moisture content recruitment of raw material rice moisture content, and, the moisture content of clean rice is adjusted in the scope of 14 weight % to 15 weight %.Promptly, in step 706, under the situation of clean rice moisture content less than 14 weight %, in step 708, automatic or manual (utilizing operation board) carries out being weakened by control device 50 attraction of fan, reduce the rotary speed of dry motor 208, weaken the adjustment control of the intensity etc. of heater 216 and air conditioner, by like this, in the time of dried feed rice in drying section 16, reduce the flow of warm braw, increase the flow of raw material rice, reduce the temperature of surrounding gas, raise and surround the humidity of starting, thereby can improve the moisture content of clean rice.And, in step 706, surpass under the situation of positive 0.5 weight % in recruitment corresponding to the clean rice moisture content of raw material rice moisture content, perhaps surpass under the situation of 15 weight % at the clean rice moisture content, in step 708, automatic or manual (utilizing operation board) is strengthened the attraction of fan by control device 50, improve the rotary speed of dry motor 208, the intensity of enhancing heater 216 and air conditioner etc. is adjusted control, when at drying section 16 dried feed rice the time, increases the flow of warm braw, reduce the flow of raw material rice, improve the temperature of surrounding gas, reduce the humidity of surrounding gas, thereby reduce the moisture content of clean rice.

In step 708, adjust by the intensity of 50 pairs of fans of control device, dry motor 208, heater 216 and air conditioner or switch control after, return step 704, detect the moisture content of raw material rice and clean rice, below repeat same operation.

Thereby, recruitment corresponding to the clean rice moisture content of raw material rice moisture content is adjustable in the positive 0.5 weight %, the wash water (washing juice) that can control in the rice washing part 12 dirt that contains aleuron residue etc. when washing meter immerses the material rice, obtains the good clean rice of taste.

And, because the moisture content of clean rice is adjustable in the scope of 14 weight % to 15 weight %,, simultaneously, can prevent mouldyly or corrupt so can prevent from the skin section of clean rice, to take place be full of cracks so that its taste is good, have good keeping qualities.

Below, the step that explanation is used to adjust rice material (raw material rice) and handles the moisture content (moisture is poor) of rice (clean rice) according to Fig. 9.
