This cloudy rice stoving separator can carry out even drying to the glutinous rice to promote drying efficiency.
When the glutinous rice is continuously and uniformly dried by the glutinous rice drying and separating device, the water content, the rehydration rate, the appearance structure and the sensory quality of the glutinous rice are obviously influenced by different drying temperatures and drying times. The rice grains are easy to yellow and have cracks on the surface due to excessively high drying temperature, the integrity of the product is damaged, and the mouthfeel is affected; the gelatinization degree of the glutinous rice is lower when the drying temperature is lower, and the higher the gelatinization degree in the starch is, the easier the gelatinization degree in the starch is decomposed by amylase, so that the glutinous rice is not easy to digest and absorb by human bodies. Therefore, a continuous drying system for the black rice is required.
Disclosure of Invention
The scheme provides a continuous drying system for the Yinmi to when carrying out continuous drying to the glutinous rice after cooking the cooling, improve the gelatinization degree of glutinous rice and be convenient for the human body to absorb, also keep the taste that traditional method preparation Yinmi has.
1. In order to achieve the above object, this scheme provides a cloudy rice is with continuous drying system, includes: the frame, still include a sieve section of thick bamboo and fan, a sieve section of thick bamboo slope sets up, be equipped with the apopore on the sieve section of thick bamboo outside, a sieve section of thick bamboo both ends still are equipped with pan feeding mouth and discharge gate respectively, a sieve section of thick bamboo with the frame rotates to be connected, the fan be located in the below frame of a sieve section of thick bamboo and with frame fixed connection, the fan is equipped with the air outlet, the air outlet of fan still is fixed with and is used for heating the air temperature of fan air outlet department to 65-75 ℃ heating resistor, the air-out direction of air outlet is towards the apopore, still be fixed with in the frame and be used for driving sieve section of thick bamboo pivoted motor, wherein, the air outlet of fan with the distance of apopore is 40 cm. .
The working principle of the basic scheme is as follows: glutinous rice is cooked thoroughly, puts into a sieve section of thick bamboo with glutinous rice from the pan feeding mouth of a sieve section of thick bamboo, then switches on the motor, makes a sieve section of thick bamboo rotate in the frame (the epaxial action wheel of motor drive passes through first belt promptly, drives the epaxial first driven wheel of sieve section of thick bamboo output, makes a sieve section of thick bamboo rotate according to certain speed), and the fan also begins the operation to produce hot-blastly simultaneously (the epaxial first driven wheel of sieve section of thick bamboo output and the second of setting in the frame are also begun to rotate through the second belt from the driving wheel). The heating resistor is arranged at the air outlet of the fan, so that the temperature of hot air generated by the fan is 65-75 ℃ all the time. Because the air outlet direction of the air outlet of the fan faces to the water outlet hole of the screen cylinder, 65-75 ℃ hot air generated by the fan can continuously enter the screen cylinder from the water outlet hole, so that the sticky rice in the screen cylinder can be dried while the surface temperature of the sticky rice is always kept at a constant level, the sticky rice can be continuously gelatinized at 56-67 ℃ (because the distance between the air outlet of the fan and the water outlet hole is 40cm, part of heat can be dissipated when the sticky rice does not reach the water outlet hole of the screen cylinder, and the proper temperature for pasting the sticky rice, namely 56-67 ℃), and the sticky rice can be continuously gelatinized (the sticky rice contains moisture and can form a sticky and uniform transparent paste solution at a certain temperature). The glutinous rice is finally discharged from the discharge hole after being dried for a certain time. (i.e., the screen cylinder is placed obliquely, so that the continuously dried glutinous rice is discharged from the discharge port due to its own weight).
Has the advantages that: when the screen drum rotates, due to the action of centrifugal force, moisture in the glutinous rice in the aggregation state (which is adhered to form a lump or a great lump) is separated out from the center of the aggregation state and slowly moves from the inside of the aggregation state to the surface of the aggregation state. In the process, the aggregation state is gradually dispersed from a large aggregation state to a small aggregation state (namely, the aggregation state is divided into a plurality of small lumps from a large lump) due to the reduction of mutual acting force.
However, under the action of hot wind, the surface of the small lumps is gelatinized and the moisture is evaporated, and the starch is mainly gelatinized in the small lumps. That is, both the external part and the internal part are performed simultaneously, and mainly gelatinization. When the moisture is reduced to a certain degree, the bonding capacity of the surface of the small lump is gradually reduced (the small lump is prevented from being gathered into a large lump again), the gelatinization is mainly used in the small lump, the moisture is still reduced under the action of temperature, the bonding capacity in the small lump is gradually weakened, the small lump is decomposed again, and finally the aim of drying the particles clearly is achieved. Namely, hot air can be firstly contacted with the surface of the glutinous rice dough, so that the drying rates of the outside and the inside of the glutinous rice dough generate larger difference, the outside drying is preferentially realized, and the glutinous rice dough is prevented from being adhered together again; then inside moisture reduces, decomposes gradually, and the clear dry effect of granule is realized to the process of repeated outside drying, and at the in-process of repeated outside drying, the micelle outside of newly decomposing has the adhesion, rotates the in-process at a sieve section of thick bamboo, and the micelle can roll in a sieve section of thick bamboo, has the surface of stronger adhesion, can bond in a sieve section of thick bamboo (after bypassing the round), again with hot-blast contact, realizes the enhancement drying of alignment, avoids the uneven problem of drying.
Because hot-blast from up blowing down, when glutinous rice was located a sieve section of thick bamboo bottom, wind-force reduced glutinous rice to the pressure of a sieve section of thick bamboo (offset partial gravity promptly), when glutinous rice was located the side, gravity and a sieve section of thick bamboo holding power nonparallel have also reduced glutinous rice to the pressure of a sieve section of thick bamboo, have reduced the condition of glutinous rice adhesion on a sieve section of thick bamboo. In addition, when the glutinous rice balls are dried to a certain degree, the glutinous rice balls are not bonded to the inner wall of the screen drum, one side with strong bonding force can leave the side face of the screen drum, and can roll continuously on one side of the screen drum, so that the centrifugal force is utilized to accelerate the removal of internal moisture, and the glutinous rice balls can be automatically decomposed after the internal acting force is reduced.
65-75 ℃ that the fan produced is hot-blast, in continuously entering into a sieve section of thick bamboo always from the air outlet direction, can make on the one hand because the effect of centrifugal force glues the cloudy rice of a sieve section of thick bamboo inboard, raise again in a sieve section of thick bamboo and discharge toward the discharge gate, on the other hand can accelerate air flow because the effect of hot-blast, make faster the volatilizing of moisture in the cloudy rice, thereby realize the continuous drying to cloudy rice, promoted dry efficiency by a wide margin, realize better dewatering effect.
When 65-75 ℃ hot air is blown out from the fan to enter the screen cylinder and contacts with the glutinous rice, the temperature on the surface of the glutinous rice is always kept at a certain level due to partial heat dissipation, the glutinous rice can be continuously gelatinized while being dried to remove water, the gelatinization degree of the glutinous rice is improved (the higher the gelatinization degree in starch is, the easier the gelatinization degree is decomposed by amylase), so that the glutinous rice is convenient for human digestion and absorption, the phenomenon that the gelatinization degree of the glutinous rice caused by too low temperature affects human digestion is avoided, and the phenomenon that the internal structure of rice grains caused by too high temperature is damaged (namely, the finished product is still in the shape of rice grains instead of aggregation formed by excessive adhesion) and the taste of a user is affected is also avoided. When hot air blows to the sticky rice in the sieve tube, the sticky rice is a sticky glutinous rice cluster, and the air penetrates through gaps of the sticky rice cluster to reduce the contact between the sticky rice and the sticky rice, so that the separation of part of rice grains in the sticky rice cluster is realized.
In conclusion, this scheme produces centrifugal force through the rotation of a sieve section of thick bamboo, can gather the moisture of the glutinous rice in the gathering state and separate out for the glutinous rice is dispersed into little gathering state by big gathering state, has realized better dehydration to the glutinous rice. When the small glutinous rice in the gathering state is under the action of stable hot air (the temperature of the hot air is 65-75 ℃), the gelatinization degree of the glutinous rice is also improved. When the sticky rice is repeatedly dried, the bonding force of the sticky rice is reduced, and the effect of drying with clear particles can be better realized. In the process of repeating external drying, the alignment enhancement drying can be realized, and the problem of uneven drying is avoided.
Further, still include first belt and second belt, be fixed with the action wheel on the transmission shaft of motor, be fixed with first from the driving wheel on the output shaft of a sieve section of thick bamboo, the action wheel is connected through first belt with first follow driving wheel, still be fixed with the second in the axis of rotation of fan from the driving wheel, first follow driving wheel is connected through the second belt with the second follow driving wheel.
Has the beneficial effects that: the epaxial action wheel of motor drive passes through first belt, and the first follow driving wheel that drives sieve section of thick bamboo output shaft is rotatory, can make a sieve section of thick bamboo also rotate according to certain speed, has avoided the motor to directly act on a sieve section of thick bamboo with the kinetic energy that the electric energy was converted into, causes a sieve section of thick bamboo slew rate too fast, probably causes danger. Meanwhile, kinetic energy generated by the motor can be transmitted from the first driven wheel to the second driven wheel through the second belt, so that the fan can continuously generate the fan, the fan rotates synchronously with the screen drum, and resources are saved.
Further, the water outlet holes are formed in multiple numbers and are evenly distributed on the surface of the screen drum.

And finally discharging the glutinous rice from a discharge port after the glutinous rice is dried for a certain time. (i.e., the screen cylinder 31 is disposed obliquely so that the continuously dried glutinous rice is discharged from the discharge hole due to its own weight). Sieve section of thick bamboo 31 is because the effect of centrifugal force when rotating, moisture in the glutinous rice can rather than separating to 34 discharges through the apopore on the sieve section of thick bamboo 31, thereby get rid of the moisture in the cloudy rice, can improve the drying efficiency to the glutinous rice. Simultaneously 65-75 ℃ that fan 43 produced is hot-blast, continuously enter into a sieve section of thick bamboo 31 from the air outlet direction always, can make on the one hand because the effect of centrifugal force glues the cloudy rice in a sieve section of thick bamboo 31 inboard, raise again in a sieve section of thick bamboo 31 and discharge toward the discharge gate, on the other hand is because the effect of hot-blast, can accelerate the air flow, make faster the volatilizing of moisture in the cloudy rice, thereby realize the continuous drying to cloudy rice, dry efficiency has been promoted by a wide margin, realize better dewatering effect. When 65-75 ℃ hot air is blown out from the fan 43 to enter the screen cylinder 31 and contacts with the glutinous rice, the temperature on the surface of the glutinous rice is always kept at a certain level due to partial heat dissipation, the glutinous rice can be continuously gelatinized while being dried to remove water, the gelatinization degree of the glutinous rice is improved, (the higher the gelatinization degree in starch is, the easier the gelatinization degree is decomposed by amylase), so that the glutinous rice is convenient for human digestion and absorption, the phenomenon that the gelatinization degree of the glutinous rice caused by too low temperature affects human digestion is avoided, and the phenomenon that the internal structure of rice grains caused by too high temperature is damaged to influence the taste of a user is also avoided. When hot air blows to the sticky rice in the screen cylinder 31, the sticky rice is a sticky glutinous rice cluster, and the air penetrates through gaps of the glutinous rice cluster to reduce contact between the sticky rice and the sticky rice, so that separation of part of rice grains in the glutinous rice cluster is realized.
