Specification

DESC:TECHNICAL FIELD
[001] The present disclosure relates generally to agriculture devices and/or apparatuses. In particular, the present disclosure relates to an apparatus for reducing moisture content from food grains.

BACKGROUND
[002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[003] In order to get stored for extended periods of time, paddy and comestible material must be dried to a moisture content much less than that is present at harvesting. Typically, freshly harvested or rough/paddy rice will have a moisture content of approximately 15-25% by weight. This moisture content level must be reduced prior to storing the paddy otherwise the paddy will mold or ferment. In order for the paddy to be storage stable, it must have a moisture content no higher than 14% by weight and more preferably between about 12-14%. For other forms of comestible material specifically herbs, spices, fruits, and vegetables, the moisture content immediately following harvest will be such so as to render the material unsuitable for extended storage. More specifically, the moisture content of rosemary immediately following harvest will be about 58% by weight. Again, unless the moisture content level is reduced, the rosemary will degrade upon storage for extended periods of time. In order to be storage stable, the rosemary must be dried to a moisture content of less than about 10% by weight and more preferably between about 8-9%.
[004] Currently, the conventional process for drying-paddy involves placing the paddy in column driers that are approximately 12-18 inches in diameter and, using ventilation ports at various locations in the column wall, blowing hot air across the paddy. The paddy moves vertically through the column beginning at the top and is drawn from the bottom of the column by an auger, with the paddy becoming drier as it approaches the bottom. However, it has been discovered that the paddy nearer the column wall will be heated to a higher temperature than the paddy nearer the column centre. For this reason, paddy cannot be dried continuously, instead, the paddy must be allowed to intermittently cool down, rest or temper before further drying. It is important that the temperature of the paddy not exceed 110° F. during the drying process or else the escaping moisture will cause the rice kernel to fracture, thus making the rice of a lower grade or quality. Typically, it takes about 3-5 days to dry paddy according to this process.
[005] The most widely used process for drying other comestible material consists of blowing warm air over the material on a multistage conveyor. For those other materials, care must be exercised during the drying process so that the materials are not damaged. For example, rosemary is typically dried in this fashion and while the temperature of the rosemary during the drying process is not as critical as that of paddy, care must be exercised in heating the rosemary so as not to scorch it or cause degradation. The conventional process for drying rosemary is also time consuming as it can take up to 24 hours to dry rosemary to the required moisture content.
[006] The basic approach to drying has remained essentially the same since the 1840's: blowing heated air through the grain followed by ventilation just for cooling. It has been assumed that heating the grain was the only method for accelerating drying. In those instances where researchers did cool their grain to aid drying, they only did so as a one-time procedure.
[007] Relative humidity (RH) and its companions—Equilibrium Moisture Content (EMC) and Equilibrium Relative Humidity (ERH)—have remained the principal control variables. On occasions, grain moisture sampling is used for direct feedback. On the surface, these concepts appear quite reasonable; however, our drying research has uncovered the following:
1) Relative Humidity, as a control in itself, is fundamentally flawed.
2) Grain Moisture feedback, as commonly used, is also flawed.
3) The use of constant heat does not produce drying optimization.
4) The standard methods for solar heating are often counter-productive.
5) The ‘wet warming’ of grain during warm fronts followed by the planned use of cooling during the nights of cold fronts, is much more efficient than continuous heating.
[008] There is therefore a need in the art to develop an apparatus that allows efficient heating of food grains in real-time and to provide moisture-reducingapparatus that is cost effective, time efficient and easy to implement.

Psychrometric calculations:
[00108] In an exemplary embodiment, following data is considered assuming climatic condition prevailed in the month of November in a given region (here in India).
Relative Humidity,??=????%
Ambient Air temperature, ????=????????
Corresponding to ?? and ????, we get Specific humidity, ??= ??.????????????/????????????????????
Temperature of air to be raised to ????=????????
Corresponding to ?? and ????, we get ????=????%
Maximum relative humidity, ???????? at ????=???????? is 42%
Corresponding to ??????????????????, ????????=??.??????????/????????????????????
???=????????- ??=??.??????-??.????????=??.????????????/????????????????????
Weight of moisture evaporated, M = 1.62 kg
1 kg of dry air added for ?? moisture content
For ??? unit moisture content, dry air added = 1kg
For 1 unit moisture content, dry air added = ??????
For 1.62 kg moisture content, dry air added =??.??????.????????????=????.??????????
So, 72.973 kg of dry air per 15 min. is required to reduce the moisture content in paddy from 24% to 12%
So, ????=????.??????????/??????????
Assuming losses, ????=??×????.??????????/??????????=??????.??????????/??????????
Mass of air required per second, ?? =??????.??????????×????????/??=??.??????????/??
Specific Volume, ??=??.????????/????
Volume flow rate of air =??×??=??.????????/????× ??.??????????/?? = ??.??????????/??

Heat Calculations:
a) Assume, heat required to raise temperature of air = ????
Specific heat capacity of air =????????.????/??????
Air temperature, ????=????????. ????=?????(????-????)?????=??????.??????×(????-????)×????????.??=??,??????,??????.?????? — (??)

b) Heat required to raise the temperature of moisture present in paddy =??m
Specific heat of water, Cw =??.??×????????/??????
Latent heat of water, QL=????????×????????/????
Assuming ambient temperature = Paddy temperature = ????.
???? =????????(??????-????)+???????
=??.????????×??.??×??????????/??????×????+ ????????×????????/????×??.????????= =??,??????,???????? — (??)

c) Heat required to raise the temperature of paddy, ????=?????(????-????)?????
Assuming the temperature of paddy goes high up to 50?. So, ????=?????
Specific heat of paddy, ????=??.??×????????/??????
Mass of paddy, ????=????.??????.
So, ????=????.??????×(????-????)×??.??×????????/?????? = ??????,???????? — (??)

[00109] In an exemplary embodiment, the frame 124 of apparatus 100can be enclosed in a hollow insulated cuboidal body.An insulation material that is used for the cuboidal body is glass wool with thermal conductivity, ??0 = 0.04 W/mK. The insulation material can be stuffed in between mild steel walls, which are held together by riveting.
[00110] FIG. 5 illustrates a detailed cross section representation of insulated covering of a frame in accordance with an embodiment of the present disclosure.
[00111] FIG. 6 illustrates an exemplary layout of a cross section of insulated wall of heating chamber in accordance with an embodiment of the present disclosure. As shown in FIG. 6, ????1,????2??????????3represent thermal resistances for walls A, B and C respectively.
[00112] For wall A:
The dimensions of ?????????? = 4.053 ?? × 4.000 ?? ×0.980 ??
Thermal conductivity of mild steel, ??0= 46 ??/????
Thickness, ????=??.????????
Face 1
Resistance, ????1?? =????/??????2??=??.??????/(????×??.??????×??.??????)=??.????×????-????/??
Face 2
Resistance, ????????=????/??????????=??.??????/(????×??.??????×??.??????)=??.????×????-????/??
Face 3
Resistance, ????????=????/??????????=??.??????/(????×??.??????×??.??????)=??.????×????-????/??
[00113] For wall B:
The dimensions of ?????????? = 4.055 ?? ×4.002 ?? ×0.982 ??
Thermal conductivity of wall B, ??1 = 0.04 W/mK.
Thickness, ????=??.????????
Face 1
Resistance, ????1??=????/??????????=??.??????/(??.????×??.??????×??.??????)=??.????????/??
Face 2
Resistance, ????2??=????/??????????=??.??????/(??.????×??.??????×??.??????)=??.????????/??
Face 3
Resistance, ????3??=????/??????????=??.??????/(??.????×??.??????×??.??????)=??.??????????/??
[00114] For wall C:
The dimensions of ?????????? = 4.155??×4.102??×1.082??
Thermal conductivity of wall C, ??0 = 46 W/mK.
Thickness, ????=??.????????
Face 1
Resistance, ????1??=????/??0??1??=??.??????/(????×??.??????×??.??????) =??.??????×????-????/??
Face 2

So, Heat flow through face 1, =(??1-??2)/(????1??+????2??+????3??)=(500??-200??)/(??.????×????-??+??.??????+??.??????×????-??) = 389.6 ??.
Heat flow through face 2, =(??1-??2)/(????1??+????2??+????3??)=(500??-200??)/(??.????×????-?? +??.??????+??.????×????-??) =94.34 ??.
Heat flow through face 3, = (??1-??2)/(????1??+????2??+????3??)= (500??-200??)/(??.????×????-??+??.????????+??.??????×????-??) =95.6 ??.
Total heat loss =2×(389.6 ??+94.34 ??+95.6 ??)=1159.08 ??.
Adding equations (1), (2) and (3), total heat input in 15 minutes =4,199,040 ??+ 769,500 ??+4,405,088.12 ??=9,373,628.12 ??.
Heat input per second =9373628.12/(15×60)??= 10,415.14 ??.
Heat to be supplied =10,415.14+1159.08=11,574.22 ??
Assuming Losses =10%.
So, heat to be supplied to keep the system running in steady state conditions =10%× 11,574.22 ??+11,574.22 ??=12,731.642 ??.
Note: If 4 heating rods are added beneath each plate, then total no. of heating rods = 4×9=36.
Power of each heating rod should be =12731.642/36 ??= 353.66??.
[00115] FIG. 7 illustrates an exemplary representation of frame with heating rods beneath the hot plates in accordance with an embodiment of the present disclosure.
[00116] FIG. 8 illustrates an exemplary enlarged representation of frame with rod without hot plates at the top (R) in accordance with an embodiment of the present disclosure. As shown in FIG. 8, (X) represents the pipes to which the heating rods are attached. The pipes are attached to the frame and carry the wires from the heating rods to the outside of the chamber for electrical connections.
[00117] FIG. 9 illustrates an exemplary schematic arrangement of cam follower mechanism in accordance with an embodiment of the present disclosure. In an exemplary embodiment, the vibrating mechanism can be incorporated in the model to make the food grain travel on the path at desired speed. Thus, enabling increase or decrease of time of travel inside the heating chamber. One end of the plate along the travel path is spring supported and the other end has roller support. Cam-follower mechanism can be used to provide the required vibration to the plate, as the reciprocating part (follower) hits the plate from the beneath (on the end with spring support).The cam is attached to the motor shaft on top of which a rod reciprocates. A hitting frequency can be varied by changing RPM of motor and amplitude of vibration can be changed by changing off-set distance from the motor shaft. Both of these methods can be used to control the flow speed of the grain on the hot plate, which helps in varying the amount of heat transfer to the grains.
[00118] FIG. 10 illustrates an isometric representation of a frame without plates and heating rods in accordance with an embodiment of the present disclosure.
[00119] FIG. 11 illustrates an enlarged representation of frame in accordance with an embodiment of the present disclosure.
[00120] FIG. 12 illustrates an exemplary schematic representation of the plurality of hot plates in a single pass with supports in accordance with an embodiment of the present disclosure. As shown in FIG. 12, V1 represents cam follower mechanism for providing vibration to first plate. S1 represents a spring support for first plate. There is another spring for first plate but is hidden in the image due to the view. R1 (plural) represents the bearing housings. A circular rod passes through the bearings in them on which an end of plate can be supported. This constitutes the roller support for the first plate. As the follower hits the spring supported end, the plate bounces about its roller support. Only 2-5 mm deflection is allowed for the plate. Right after the first plate ends, with a minimal gap, second plate starts. Spring supports for second plate are shown in the image as S2. Vibration mechanism for the second plate is shown as V2.
[00121] FIG. 13 illustrates an enlarged side view representation of the frame for vibrating support mechanism in accordance with an embodiment of the present disclosure.
[00122] FIG. 14 illustrates an enlarged side view representation of frame with plate on top in accordance with an embodiment of the present disclosure.
[00123] FIG. 15A illustrates an exemplary isometric representation of hopper in accordance with an embodiment of the present disclosure.
[00124] FIG. 15B illustrates an exemplary top view representation of hopper in accordance with an embodiment of the present disclosure.
[00125] FIG. 15C illustrates an exemplary representation of guides at hopper outlet in accordance with an embodiment of the present disclosure.
[00126] As shown in FIG. 15A to 15C, food grains can enter the drier or apparatus through the hopper. The flow rate of grains can be controlled by turning the handle that turn the small guides increasing or decreasing the area between them thus increasing or decreasing the flow rate of grain.
[00127] FIGs. 16A to 16D illustrate exemplary layout representations of PLC circuit in accordance with an embodiment of the present disclosure. The heat added to the grains is to be varied depending on the moisture content to be reduced. This is controlled with the help of the logic circuit based on PLC programming. The circuit works according to the circuit diagram shown in the FIG. 16A.
[00128] As shown in FIG. 16D, R’, R’’ and R’’’ represent NC contacts, which are connected to temperature controllers. The connection of R’ has been shown in Fig. 16D. R’’ and R’’’ are also connected in a similar way. The above circuit helps in controlling the speed of motors using a variable frequency drive and the number of heating elements to be switched on/off during the drying process can be dependent on the moisture content. Further, the temperature of the plates is not to be raised above 490??. This can be achieved by using temperature sensors and temperature controllers. Hence, controlled heat can be added to the grains to prevent its overheating and to prevent heat loss.
[00129] FIG. 17A to 17C illustrate exemplary representations of heating chamber in accordance with an embodiment of the present disclosure. In an embodiment, exhaust fans can be provided at the top to extract the humid air from the heating chamber to the outside and to suck the air from outside into the heating chamber. Three 6’ duct vent fans are added at the top. The volume flow rate through the fans can be set to desired (??.??????????/??????) by changing the RPM of fan (which changes the air velocity through the duct). The air velocity through the fans can be measured using Anemometer. The air may enter through the inlet at the bottom and flow through the holes provided in the plates reaching the top and exiting through the fans. In case, the fans are unable to overcome the system resistance, two fans at the side walls have also been provided represented as air outlets 4 & 5 in the image. The inlet for each fan is on the opposite wall. The inlets are such that the direction of air flow is against the direction of grain flow in aparallel direction. The volume flow rate through each of these fans is one-third of the total volume flow rate through the fans provided at the top, i.e., 0.159/3=0.053??3/??????. Valves are provided at each air outlet.
