The present invention relates to a malt germination dryer, and more particularly, by adopting a three-dimensional drum rotation method that is not two-dimensional in a plane as in the prior art, so that the drying from the germination of the malt is fully automatic, It relates to a malt germination dryer that enhances product competitiveness by maximizing convenience, work efficiency, and productivity.

From ancient times, ancestors have been used to produce agricultural products through cultivation and rearing (products obtained through cultivation or rearing, including both vegetable and animal products), as well as forest products (wood produced in forests, bamboo ash, etc.) Firewood, charcoal, boiled trees and roots, raw paper, fruit, bark, resin, fresh leaves, fallen leaves, moss, herbaceous plants, vines, swarms, soil stones, mushrooms, etc. Can be stored for a long time to make it edible, such as freezing, salting, and drying.

In the storage method of the agricultural products, wind or sunlight is used for drying.

However, there is a problem in that the reliability of natural drying of agricultural products through wind or sunlight is deteriorated due to the seriousness of environmental pollution while going through modernization and industrialization through the development of civilization.

Accordingly, various drying devices have been devised to obtain the reliability of agricultural products dried products.

Looking at an example, the registered utility model No. 20-126650 has an oil burner, a blower, an air inlet, a communication and an outlet formed on one side of the dryer, and the hot air passage and the hot air distribution chamber are alternately formed in the frame of the rectangular hot air distribution pipe. By forming a division, a porous base plate with a large inner diameter is mounted on the bottom of the hot air distribution chamber, and a porous top plate with a small inner diameter is mounted on the hot air passage and the upper surface of the distribution chamber, and several hot air distribution pipes are installed in parallel at regular intervals above and below the drying chamber. Therefore, a guide plate of different height is formed in the hot air passage so that the hot air passage is related to the air blower, and the primary hot air is distributed through the hot air passage. At the same time, the secondary hot air rises through the distribution chamber and mixes with the primary hot air to be the same in the drying room. It is to dry by temperature distribution.

However, there is a problem in that drying and work efficiency are remarkably deteriorated because the worker must manually withdraw or receive the hot air distribution plate for drying agricultural products.

In addition, there is a problem in that the amount of drying is small compared to the volume, resulting in personal and financial damage.

Looking at another example, Patent Publication No. 10-535189 provides a hopper for accommodating a large amount of agricultural products, and a screw connected to the lower portion of the hopper to transfer the agricultural products accommodated in the hopper to be rotatably installed. A wire mesh with fine holes is fixed on the outer periphery, a steam pipe supplying steam is installed at a predetermined position, and an air pipe supplying air is installed at a predetermined position, and a drying pipe is installed primarily for transported agricultural products. In the same configuration as this drying pipe, secondary and tertiary drying pipes are continuously connected and installed, and an outlet is provided at the end thereof.

Through this drying device, the agricultural products are dried without altering the color of the agricultural products, and by sequentially drying the agricultural products, they are dried without destroying the components contained in the agricultural products, and a large amount of agricultural products is supplied to the hopper at the same time. Can be dried.

However, the above-described conventional technique has a problem of having a usability limited to drying agricultural products.

On the other hand, the dietary lifestyle mainly based on instant foods or meat triggers the phenomenon of acid poisoning of the blood and is a major cause of adult diseases, and in order to solve this, it is necessary to consume more dietary fiber, which is insufficient by meat diet by eating grains and vegetarian diets.

Since the above dietary fiber is contained in large amounts in grains such as germinated brown rice, when ingested, it increases resistance to disease, prevents acid poisoning of the blood, and makes the blood alkaline, thereby preventing aging and functioning in the intestines. It can be strengthened.

In particular, grains with a sprout of about 25 mm contain dietary fiber, calcium, vitamins, minerals, as well as vitamin B1 and vitamin B2, etc., so when ingesting them, per adult recommended by the World Health Organization. Not only can you satisfy your dietary fiber intake, but you don't have a problem with nutritional intake even if you don't eat meat.

For example, malt is an edible saccharification-degrading enzyme made from wheat, barley, etc. that are sprouted and dried.

The malt is commonly referred to as malt or malt, and is used to make alcohol or sikhye, including beer, and is also used as a food that gives taste or aroma to various baked foods, sugars, grain meals, starch syrup, and the like.

As described above, such malt is germinated by giving water to barley or the like, dried and pulverized, and commercialized such as malt depending on the size of the pulverized particles.

On the other hand, when manufacturing malt as described above, in particular, a manufacturer producing a large amount of malt has a cumbersome problem as follows.

In other words, after washing the top barley, an appropriate amount of moisture is supplied to the top barley to germinate, and the germinated barley is transferred to a drying device to be dried. Typically, malt manufacturers process as few as hundreds of kilograms and as many as thousands of kilograms of barley. To prepare malt, first, barley was germinated in a bath for washing the barley or in a bath for washing and germinating, and when the barley germinates, the germinated barley was transferred to a drying device and then dried.

Therefore, it took a lot of labor and time to transfer the barley germinated in the washing tank or the washing and germination tank to the drying device. Has become.

Looking at a conventional example as a way to solve the above-described problem,

The apparatus for germinating and drying grains of Patent Publication No. 10-1146434 is installed on the upper side of the tank to be spaced apart from the tank 10 having a pool shape with a drain hole 11 formed on the bottom surface, and the inner bottom surface of the tank 10 And a mounting plate 20 having a plurality of drainage holes 21 formed thereon, and a moving part installed across the narrow upper side of the tank 10 and selectively moving forward and backward along the longitudinal direction of the long width of the bell (30) And, a plurality of rotating parts that are mounted on the moving part (30) and vertically arranged in the inside of the bath (10) for stirring and rotating, and installed adjacent to the bath (10), and the bath (10) and the red It is composed of a hot air supply unit that supplies hot air to the space formed between the trials 20, and a control unit 60 that is electrically connected to the moving unit 30, the rotating unit, and the hot air supply unit to selectively control their operation. .

However, the conventional malt germination dryer has a problem in that the production efficiency is inferior because it is configured in a flat type and cannot perform uniform germination and drying operation.
