Description

Rotary Dryer for Pretreatment Drying of Green Whole Grains

The present invention relates to a rotary drying apparatus for pre-treatment drying of green whole grains, and more particularly, to steaming grains such as barley of a ripening season, and steaming the whole grains without sticking to the juicy green whole grains on the surface. It relates to a rotary drying apparatus for pretreatment drying of green whole grains that can be pretreated and dried.

Typically, the green whole grains (Green Whole Grain) is a grain that is used green bottle barley, green wheat, green tongssal, to talbu only the green status crusted including green tongssal oats means the grain is not milled, typically stocks While the grain is ripe enough to be harvested in the ripening season, after it is threshed, dried, milled or milled, it is edible, while the green whole grains are just before the ripening of the barley, wheat, rice, and oats to turn yellow. It contains chlorophyll, which is harvested in green, and processed to be used as stock or food. Grains harvested in ripening season have lost both bran and seed snow when they are milled, and in the case of brown rice, the seed flakes are included, but the rice grains are not completely removed. Is the reality. Barley rice must be boiled before cooking to produce a soft texture to some extent, wheat has to be used only as a powder product, and also had the disadvantage that the seed and the layer are completely removed. Therefore, in many countries, only the whole wheat flour and the seedlings selected after milling are used as products, but also the consumption is not increased significantly because the texture is lower than conventional flour.

Existing barley rice was threshed during the ripening season and was not edible as whole grains, so it was boiled (milled) and boiled or pressed before being mixed with rice and used for cooking. However, due to the characteristics of barley, the texture is not soft and the taste is slightly lowered due to a bitter taste, but it is used as a health food in its own way, but the consumption is not increased significantly. As a result, even if it is used as a healthy diet, there was a limit to the use of dietary foods with the loss of essential nutrient layers and embryos of Gojiriri, which have been lost to refinement or treatment.

In addition, in order to reduce the rough and hard texture even a little for the use of edible waxy barley breeding and edible, but edible, but without going through the road, you can not eat nutritious insight barley. In the port, purple barley is bred and developed as a functional grain with pigments, but these pigments are mainly contained in the grain layer of whole grains, so most of the pigment layers are lost during the process of milling.

It is true that whole grains are nutrient-rich, but it is more cumbersome when cooking for cooking, it is rough and not easy to eat, and it is easy to eat and softens the texture due to limited intake due to indigestion. It is used only in the state of crushing (milling) the nutrient-rich grains of grains.

As a prior art for solving the above problems, Korean Patent Registration No. 10-1231000 (Notice Date: 2013.02.07) discloses a process for processing and mass production of green whole grains.

In addition, the drying housing 20 may have an outlet 24 lower than the inlet 22 so that the green whole grains supplied therein can move smoothly toward the outlet 24.

The drying housing 20 may be configured to have a diameter of about 1 to 2 m for smooth pretreatment drying and movement of the green whole grains steamed and containing a large amount of water on the surface.

The inlet 22 of the above-mentioned dry housing 20 is provided with the hopper 25 for injecting the green whole grains supplied by the conveying means 60 into the inlet 22. Inside the hopper 25, a porous dispersion plate 25A for dispersing the green whole grains fed and transferred by the transfer means 60 is installed.

The porous dispersion plate 25A is for dispersing the aggregated green whole grains supplied by the transfer means 60 so as not to aggregate together. That is, the steamed green whole grains contain moisture having a viscosity on the surface thereof, and when the green whole grains are entangled and agglomerated with each other, the drying efficiency deteriorates, so that the green whole grains are supplied into the drying housing 20. In order to disperse the green whole grains as much as possible, the porous dispersion plate 25A is installed in the hopper 25.

In addition, the porous dispersion plate 25A may be provided with a plurality of vibration motors 25B for vibrating the porous dispersion plate 25A to help individual dispersion of green whole grains.

As described above, the porous dispersion plate 25A is supported by the upper and lower elastic bodies 25-3 such that the porous dispersion plate 25A is positioned between the upper body 25-1 and the lower body 25-2. When the vibration motor (25B) is installed in each corner of the operation, the porous dispersion plate 25A is vibrated and the green whole grains, which are agglomerated with each other by moisture and stickiness (adhesive force), are easily dispersed individually.

On the other hand, the warm air generator 30, the inlet of the drying housing 20 so that the pre-treatment drying of the green whole grains that are transported while falling while moving upwards by the transfer blades 26 inside the rotating drying housing 20 is made It is provided on the (22) side for supplying warm air with low humidity to the inlet 22 of the drying housing (20). The hot air generator 30 supplies power to the heating wire to generate heat, and operates the blower fan to supply the inlet of the drying housing 20 in a state where the air is changed to dry high temperature air while passing through the region in which the heating wire is installed. It may be configured to.

In addition, a dehumidifier 32 may be installed at the air inlet side of the warm air generator 30 to lower the humidity of the warm air supplied into the drying housing 20. That is, to remove moisture from the air supplied to the warm air generator 30 so that the air supplied into the drying housing 20 is dried at a high temperature. By passing through the drying housing 20 by the dehumidifier 32, the green whole grains may be efficiently dried.

In particular, when the plurality of vibration motors 25B provided in the porous dispersion plate 25A operates, the porous vibration plate 25A vibrates, so that the green whole grains in the aggregated state are more smoothly made.

On the other hand, the warm air generator 30 is forced through the dehumidifier 32 to heat the dry air is removed to the inside of the drying housing (20).

When the green whole grains are supplied to the hopper 25 and the dry warm air is supplied into the drying housing 20, the green whole grains supplied into the drying housing 20 are spirally connected to the inner circumferential surface of the drying housing 20. It is gradually moved upwardly in the rotational direction of the drying housing 20 by the respective transfer blades 26 installed, and then gradually falls from the inlet 22 toward the outlet 24 by the dry warm air supplied by the warm air generator 30. Will move.

That is, because each of the transfer blades 26 are inclined toward the outlet 24, spirally arranged from the inlet 22 side to the outlet 24, and dry hot air is supplied from the inlet 22 side to the outlet 24, As shown in FIG. 3, green grains falling upward and falling smoothly move toward the outlet 24.

In particular, the green whole grains are swept upward by the respective conveying blades 26 arranged in a spiral shape, so that the green whole grains are blown toward the outlet 24 by dry warm air in the process of falling, thereby improving the drying efficiency of the green whole grains. It is. This drying process is similar to the process of shaking the key up and down to blow away the grain or gum. The dry hot air is supplied from the inlet 22 to the outlet 24 and the green whole grains are moved upwards and then dropped. The process is repeated while passing through the drying housing 20 so that the pre-treatment drying of the juicy green whole grains can be done efficiently.

On the other hand, the hot air outlet 40 is installed in the outlet 24 of the drying housing 20 to forcibly discharge the warm air containing a large amount of moisture can further improve the drying efficiency inside the drying housing 20.

The green whole grains pretreated by the dry warm air are repeatedly discharged to the discharge transport means 50 through the outlet 24 while repeating the above-described process of falling up from the inside of the drying housing 20 by the above-described process.

The green whole grains discharged from the discharge conveying means 50 are finally dried while being cooled by the fan device 54 for cooling air supply in the process of being transported by the porous belt conveyor 52 which is the discharge conveying means 50. . That is, when the green whole grains discharged to the outlet 24 are conveyed by the porous belt conveyor 52, air of 20 degrees C or less at the bottom of the porous belt conveyor 52 is supplied by the fan apparatus 54 for supplying cooling air. As it is discharged, the green whole grains passing through the porous belt conveyor 52 may be further dried while being cooled.

At this time, by installing a dehumidifier in the fan device 54 for cooling air supply or by installing an air conditioner, the humidity of the cooling air can be further lowered to increase the cooling and drying efficiency of the green whole grains.

As described above, the porous dispersion plate 25A is installed in the hopper 25, the dehumidifier 32 is installed in the warm air generator 30, and the drying housing 20 in which the transfer wings 26 are spirally laid is laid down. It is installed to rotate in a dark state, and the green whole grains containing a large amount of steamed steam are poured upward from the inside of the drying housing 20 and then pretreated and dried with dry warm air while falling, and finally cooled by the discharge transport means 50. And by drying, the pretreatment drying efficiency of a rusted whole grain can be improved.

In addition, in particular, the green whole grains can be continuously dried while the drying housing 20 is laid down, so that a large amount of green whole grains can be pretreated and dried smoothly.
