Device for manufacturing cereal using fluidized hot air

The present invention relates to a cereal manufacturing apparatus using a fluidized hot air drying system, and more particularly, a fluidized hot air drying system capable of improving the color, texture and flavor of cereals by roasting grain cereals using a fluidized hot air drying method. It relates to a serial manufacturing apparatus using

A look at the processed food expenditure structure of Korean households announced by the Ministry of Agriculture, Food and Rural Affairs and the Korea Rural Economic Research Institute shows that out of the total food expenditure, the expenditure on processed food is increasing while the expenditure on eating out decreases. It is recognized as a trend caused by the enemy.

In particular, as for the proportion of expenditure by processed food category, processed grain products showed the highest proportion, which is believed to be attributable to Korea's traditional eating habits with rice as a staple food.

Accordingly, at this point in time when the demand for various grain-processed foods including rice is increasing, the development of various and improved grain-processed products is required, and one of them is cereal cereals, which are simple substitutes.

As a product released by foreign companies and large companies among domestic cereal products, cereal products using rice, whole grains, superfoods, etc. are gluten-free and well-being Considering the fact that it is being released under the influence of

In manufacturing the grains including rice into cereal products, the most important thing will be the drying process that determines color, texture, and flavor.

As an example of the prior art, when the drying process for manufacturing cereals including rice into cereal products is applied as a dry method in which moisture is evaporated by simply exposing to hot air, the structure of the cereal is constituted as shown in FIG. Cells before drying (the state containing moisture) are greatly reduced due to evaporation of moisture after drying, and the external color is maintained as it is.

If the size of the cells before drying is greatly reduced due to evaporation of moisture, the texture of the cereal is hardened and the original flavor of the grain is not revealed.

As another example of the prior art, when the drying process for manufacturing grains including rice into cereal products is applied as a roasting method, as shown in FIG. state) while evaporating only the moisture in the cell, the size of the cell can be maintained as it is, and thus, the unique crispy texture of the cereal can be preserved, and the unique nutty taste of the grain can be increased.

In addition, since the surface color of the cereal product after drying is browned by the roasting method, the flavor and flavor of the cereal can be visually felt.

However, most of the existing roasting methods are batch-type hot air roasting methods, and it is difficult to evenly transfer heat to the cereal particles, so the degree of roasting between particles is non-uniform, and the yield and thermal efficiency are low. There is a problem in that continuous production and mass production are difficult.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 and 4 are schematic diagrams illustrating a grain cereal drying system of a fluidized hot air drying method according to the present invention, in which reference numeral 10 indicates a drying case.

The drying case 10 is a rectangular case in which an input unit 12 for inputting grain cereal, a product to be dried, is formed on one side thereof, and a discharge unit 14 through which the dried cereal product is discharged is formed on the other side thereof. provided in the structure.

In particular, the inner space of the drying case 10 may be divided into three sections along the longitudinal direction, and three or more hot air connection pipes for supplying hot air of different temperatures for each space of the three sections may be connected to each other. have.

In the drying case 10, a screw 20 for roasting while transferring and flowing the cereal to be dried from the input unit 12 toward the discharge unit 14 is rotatably mounted in place.

At this time, a driving device 30 for transmitting rotational force to the screw 20 is mounted on the other side of the drying case 10 .

To this end, the driving device 30 includes a chain gear formed on the rotation shaft of the screw 20 exposed through the other side of the drying case 10 and a predetermined position of the support frame supporting the drying case 10 . It may be composed of a motor mounted on the motor, a chain for power transmission connected between the output shaft of the motor and the chain gear, and a speed controller 34 for controlling the rotation speed of the motor according to the type of serial to be dried.

Accordingly, the rotational force according to the driving of the motor is transmitted to the chain gear through the chain and at the same time transmitted from the chain gear to the screw 20, so that the cereal to be dried is discharged from the input unit 12 while the screw 20 rotates in place. At the same time, it flows toward (14).

In particular, three or more hot air connectors are connected to the front portion of the drying case 10 .

Preferably, the first hot air connector 41, the second hot air connector 42, and the third hot air connector 43 are connected to the front part of the drying case 10, and the input part 12 ) to the discharge unit 14 are connected at equal intervals.

In addition, one hot air supply pipe 40 connected to the rear of each of the first, second, and third hot air connection pipes 41, 42, 43 is connected, and the hot air supply pipe 40 is connected to a hot air fan 50 .

Preferably, a hot air temperature controller 54 is connected to the hot air blower 50, and the hot air temperature generated by the hot air blower 50 is adjusted according to the type of serial to be dried by the control signal of the hot air temperature controller 54. can

Accordingly, when the hot air blower 50 is driven, the hot air generated by the hot air blower flows through the hot air supply pipe 40, and then branches into the first, second, and third hot air connection pipes 41, 42, and 43, respectively, for drying. It may be supplied into the case 10 .

At this time, in order to control the amount of hot air and the drying temperature that are branched into the first, second, and third hot air connecting tubes 41, 42, and 43 and supplied into the drying case 10, the first hot air connecting tube 41 is equipped with a first valve 51 for controlling the opening degree of the first hot wind connection pipe, and a second valve 52 for controlling the opening degree of the second hot wind connection pipe is mounted on the second hot wind connection pipe 42, , The third hot air connection pipe 43 is equipped with a third valve 53 for controlling the opening degree of the third hot air connection pipe.

Preferably, the first, second, and third valves 51, 52, and 53 may be adopted as a type whose opening degree is controlled by a drive lever that can be directly operated by an operator.

Here, an operation flow of the serial manufacturing apparatus of the present invention having the above configuration will be described as follows.

First, when the motor is driven, the rotational force according to the driving of the motor is transmitted to the chain gear through the chain and at the same time transmitted from the chain gear to the screw 20 , so that the screw 20 rotates in place.

At the same time, by driving the hot air blower 50, the hot air generated by the hot air blower flows through the hot air supply pipe 40, and then branches to the first, second, and third hot air connecting pipes 41, 42, 43, respectively, for drying. To be supplied into the case (10).

Subsequently, the cereal to be dried is put into the drying case 10 through the input unit 12 .

Accordingly, while the cereal input through the input unit 12 is transferred toward the discharge unit 14 by the in-place rotation of the screw 20, it is roasted by the hot air temperature.

At this time, when the screw 20 is rotated in place, as shown in FIG. 5 , the cereal floats in the space between the pitches of the screw, and at the same time, due to the convection phenomenon of the hot air, even drying is achieved over the entire surface of the cereal. can be made, thereby obtaining a Maillard reaction to the cereal.

For reference, the Maillard reaction refers to a phenomenon in which most ingredients change to 'brown' through the cooking process (eg, a phenomenon that turns brown when bread is baked in the oven). A flavor effect of increasing the savory and crispy taste can be obtained.

If the cereal is dried by heat applied in a short time, shrinkage occurs on the surface of the cereal, so that the moisture inside cannot come out and the internal texture is strengthened, thereby making the texture of the cereal hard.

That is, if the size of the cereal cell before drying is greatly reduced due to moisture evaporation, the texture of the cereal is hardened and the original flavor of the grain is not revealed. It is preferable to dry at a hot air temperature.

Accordingly, the opening degree of the first valve 51 is adjusted to be smaller than that of the second valve 52 , and the opening degree of the third valve 53 is adjusted to be larger than that of the second valve 52 , and the drying case It is preferable to adjust the hot air drying temperature in (10) to a temperature that increases braille from the input unit 12 to the discharge unit 14.

More specifically, by adjusting the opening degree of the first valve 51 to be smaller than the opening degree of the second valve 52, and adjusting the opening degree of the third valve 53 to be larger than that of the second valve 52, Compared to the hot air temperature supplied from the first hot air connection pipe 41 to the drying case 10 to dry the cereal, the second hot air connection pipe 42 is supplied to the drying case 10 to dry the cereal The hot air temperature is higher, and compared to the hot air temperature that is supplied from the second hot air connector 42 to the drying case 10 to dry the cereal, from the third hot air connector 43 to the drying case 10 The supplied hot air temperature to dry the cereal is higher.

For example, by adjusting the opening degree of the first valve 51 to 20%, adjusting the opening degree of the second valve 52 to 50%, and adjusting the third valve 53 to 90%, The hot air drying temperature in the drying case 10 can be adjusted to a temperature that increases from the input unit 12 to the discharge unit 14 .

Therefore, the hot air temperature for drying the cereal by being supplied from the first hot air connector 41 to the first section (eg, the section between the input part and the middle part) of the drying case 10 is adjusted to the lowest level, The hot air temperature for drying the cereal is supplied from the second hot air connector 42 to the second section (eg, the middle part) of the drying case 10 and is adjusted to the next highest temperature, and the third hot air connector 43 The hot air temperature for drying the cereal by being supplied from the to the drying case 10 can be adjusted to the highest.

Therefore, the cereal input to the drying case 10 through the input unit 12 is transferred and flowed toward the discharge unit 14 by the rotation of the screw 20 while being roasted and dried, and at the same time gradually increasing The temperature of the hot air evaporates only the moisture in the cereal cells before drying (in the state of moisture), and at the same time, the size of the cereal can be maintained without shrinkage. It can enhance flavor.

In addition, by continuously roasting and drying the grain cereal while transferring it using the screw 20, it is possible to provide the advantage of continuous roasting and mass production of grain cereal.

On the other hand, in the above embodiment, the opening degree of the first valve 51 is adjusted to 20%, the opening degree of the second valve 52 is adjusted to 50%, the third valve 53 is adjusted to 90%, etc. Although it has been described that the opening degrees of the first valve 51 , the second valve 52 , and the third valve 53 gradually increase, the first valve 51 , the second valve 52 and the third valve 53 . By adjusting the opening degree of the , the amount of hot air passing through the first valve 51, the second valve 52, and the third valve 53 and the temperature thereof are respectively set to strong, medium, weak, or strong, weak, strong, Or it can be adjusted to weak, medium, strong, etc., and thus more diverse products can be dried and produced.

Meanwhile, an anti-corrosion coating layer may be applied to the drying case 10 and the driving device 30 to prevent corrosion of the metal surface.

The coating material of this anti-corrosion coating layer is isobutylamide 12% by weight, indiazole 20% by weight, hafnium 23% by weight, molybdenum emulsified (MoS ² ) 10% by weight, titanium oxide (TiO ² ) 20% by weight, propionamide 20 It is composed of weight %, and the coating thickness can be formed to 10㎛.

Isobutylamide, indiazole, and propionamide act as corrosion protection and discoloration protection.

Hafnium is a transition metal element with corrosion resistance, and serves to have excellent waterproof and corrosion resistance.

Molybdenum emulsified serves to impart lubricity and lubricity to the surface of the coating film.

Titanium oxide is added for the purpose of fire resistance and chemical stability.

The reason why the ratio of the constituents and the coating thickness are numerically limited as described above is that the present inventors repeatedly failed several times and analyzed through the test results. As a result, the optimal anti-corrosion effect was exhibited at the above ratio.

In addition, the screw 20 , the first valve 51 , the second valve 52 , and the third valve 53 are provided with an anti-contamination composition made of an anti-contamination coating composition to effectively prevent adhesion of and remove contaminants. An application layer may be applied.

The antifouling coating composition contains amphodipropionate and alkyl glycol ether in a molar ratio of 1:0.01 to 1:2, and the total content of amphodipropionate and alkyl glycol ether is 1 to 10 based on the total aqueous solution. % by weight.

The molar ratio of the amphodipropionate and the alkyl glycol ether is preferably 1:0.01 to 1:2, and when the molar ratio is out of the above range, the screw 20, the first valve 51, and the second valve 52 , there is a problem in that the applicability of the third valve 53 is lowered or the water adsorption on the surface increases after application, so that the coating film is removed.

The amphodipropionate and alkyl glycol ether are preferably 1 to 10% by weight in the entire aqueous solution of the composition, and when less than 1% by weight, the screw 20, the first valve 51, the second valve 52, and the third There is a problem in that the applicability of the valve 53 is lowered, and when it exceeds 10% by weight, crystal precipitation is likely to occur due to an increase in the thickness of the coating film.

On the other hand, as a method of applying the present antifouling coating composition to the screw 20 , the first valve 51 , the second valve 52 , and the third valve 53 , it is preferable to apply the composition by a spray method. In addition, the final coating film thickness of the screw 20, the first valve 51, the second valve 52, and the third valve 53 is preferably 550 ~ 2000Å, more preferably 1100 ~ 1900Å. If the thickness of the coating film is less than 550 Å, there is a problem in that it is deteriorated in the case of high-temperature heat treatment, and if it exceeds 2000 Å, there is a disadvantage that crystal precipitation on the coated surface is easy to occur.

In addition, the present antifouling coating composition can be prepared by adding 0.1 mol of polyquaternium-7 and 0.05 mol of alkyl glycol ether to 1000 ml of distilled water and then stirring.

And, a vibration absorbing part made of a rubber material may be further installed at the lower end of the drying case 10.)

The vibration absorbing part may be made of a rubber material, and the raw material content ratio of this vibration absorbing part is rubber 55% by weight, organic acid cobalt salt 6% by weight, naphthalic anhydride 8% by weight, mercaptozirconate 20% by weight, 3C (N-PHENYL-N'-ISOPROPYL-P-PHENYLENEDIAMINE) 6% by weight and 5% by weight of sulfur are mixed.

Mercapto zirconate is added to increase or improve abrasion resistance, thermal conductivity, etc., and organic acid cobalt salt and naphthalic anhydride are added to improve adhesion.

3C (N-PHENYL-N'-ISOPROPYL-P-PHENYLENEDIAMINE) is added as an antioxidant, and oil is added to act as an accelerator.

Therefore, in the present invention, the elasticity, toughness and rigidity of the vibration absorbing part are increased, so that durability is improved, and thus the life of the vibration absorbing part is increased.

The reason for limiting the rubber material constituents and constituents and limiting the numerical value of the mixing ratio is that the present inventor repeatedly failed several times and analyzed the test results to show the optimal effect in the composition and numerical limit ratio it was
