In the washing step (10), which is a previous step for drying the jujube (D), the jujube (D) is washed by applying ultrasonic waves in the washing tank (11). In FIG. 2, the ultrasonic generator 12 is installed in the washing tank 11, and the ultrasonic waves generated by the ultrasonic generator 12 wash the jujube D.

Ultrasonic washing is to wash an object with ultrasonic waves of 3 to 40,000 per minute, which are generated in water, so that ultrasonic waves can act to destroy and disperse liquid particles or solids. That is, the fine bubbles generated when the sound wave is incident on the water is washed by the energy generated by reaching and bursting to every corner of the fruit, washing the contaminants without damaging the fruit.

At this time, the internal temperature of the micro-bubble is more than 5000 degrees, but because the cooling rate is 1 billion degrees per second not only does not damage the fruit at all, nor does nutrient destruction occur.

The jujube (D) washed through the ultrasonic wave is delivered from the washing tank 11 by the conveyor 13 and then transferred to the sorting machine 21 to proceed with the sorting step 20.

Separator 21 is a device for sorting the jujube (D) by size, the size of the jujube D of the size to pass through the processing work, that is, the jujube seed (D1) separation is not allowed to pass through In this case, if a screen, a chain having a sorting hole to pass through, or a net is arranged and moved in the order of smallest to largest holes, the jujube D having a smaller size than the sorting hole passes through the sorting hole, and the larger jujube. (D) passes through and sorts through a selection hole having the next large size.

Since this sorter 21 is a general apparatus, detailed description thereof will be omitted.

When the jujube (D) is selected by size, the jujube seed is removed and the jujube cut step 30 through the conveyor for each of the selected jujubes (D).

The jujube seed removal device 31 is required for the jujube seed removal and jujube cutting step.

The jujube seed removal device 31

The inside of the cylinder 34 is provided with a jujube seed discharge hole 351 at the center to be at a predetermined depth inside the jujube insertion hole 341, and when the jujube seed D1 is separated, it moves forward and is divided into pieces. A push rod 35 for discharging the pieces of jujube is installed. At the rear end of the push rod 35, a second actuator 37b for forward and backward operation is provided. In front of the inlet portion of the cylinder 34, a punch 38 having a diameter equal to or smaller than the diameter of the jujube seed D1 is installed to be able to be projected toward the jujube seed discharge holes 351 and 351. The punch 38 is provided with a first actuator 37a to move the punch 38 forward and backward. The punch 38 is in the form of a ball or rod, and the cutting edge N is formed in the periphery. Cutting edge (N) is designed to cut the jujube (D) to a certain standard, so the number is determined according to the size of the design.

The push rod 35 and the punch 38 are operated by a control unit programmed to interlock with each other. The sequence of operation is that when the retreat after the forward operation of the punch 38, the push rod 35 moves together toward the punch 38 to discharge the jujube d inside the cylinder 34, and then returns to the original position. It works in that order.

When the jujube alignment belt moving intermittently by this device transfers the jujube (D), and then stops after positioning the jujube (D) at the position of the jujube insertion hole (341), the first actuator (37a) is operated to the The punch 38 is advanced to the jujube insertion hole 341. The advancing punch 38 pushes the jujube D into the jujube insertion hole 341. When the jujube D comes into close contact with the pusher 35 inside the jujube insertion hole 341 and stops, the jujube D ) And the end of the jujube (D) in contact with the one end of the jujube seed (D1), and then the jujube seed (D1) is pushed by the force of the punch 38 to penetrate the jujube flesh of the straw 35 The jujube seed is discharged through the discharge hole 351. As the punch 38 removes the jujube seed D1 in this manner, the cutting blade N formed around the punch 38 cuts the jujube flesh into a constant size. In the figure, since the cutting blades N are composed of six and arranged in a hexagonal structure, the jujube D is cut into six pieces.

When the jujube seed removal and jujube cutting operation of the punch 38 are completed, the first actuator 37a operates in reverse to retreat the punch 38 and at the same time, the second actuator 37b operates to push the push rod 35. To advance to the punch 38 to discharge several pieces of jujube d in the cylinder 34. The discharged piece jujube (d) is moved to sit on the jujube alignment transfer belt 32 and then transferred to the drying process (40) 50, which is the next process. This jujube seed removal and cutting operation is repeated continuously.

The forward and backward movement completion positions of the punch 38 and the forward and backward movement completion positions of the push rod 35 may be set by an encoder that knows the operation positions of the first actuator 37a and the second actuator 37b. The limit switch can be used to detect and control the exact stop position.

On the other hand, the seed is removed jujube (d) pieces are moved to a drying chamber is made to dry (drying steps (40, 50)) The drying chamber is made by hot air drying, at a temperature of 45 ℃ ~ 50 ℃ 17 hours to Dry for 20 hours.

Then, secondary drying is performed again at a temperature of 60 ° C to 65 ° C. In this way, the jujube (D) becomes crunchy when chewed, making it feel like eating sweets.

When the jujube (D) is dried in this way, the packaging process is carried out. (Packaging step (60)) Since the dried jujube (D) may be dampened by moisture, vacuum packing or wrapping paper to block contact with air. Pack the desiccant inside. Packaged dry jujube (D) can be maintained for a relatively long time without corruption in the distribution process, and consumers can feel the crispy texture like cookies when eating.

The present invention can achieve homogeneity as well as improvement of product productivity and product quality by automatically performing all operations such as washing of jujube, removing jujube seed, regular shaping by cutting of jujube. In addition, in the drying process of jujube, the jujube flesh is divided into pieces and dried, thereby reducing the drying time, thereby significantly reducing the energy consumption of jujube drying.

In addition, as the jujube flesh is divided into pieces and dried, the drying efficiency is improved, and even though it is a natural fruit when chewed, it is not only crunchy like ordinary sweets but also contains a lot of sugar, so everyone can eat deliciously. In particular, as well as natural fruit confectionery does not contain any artificial seasonings can be expected to improve health by the efficacy of jujube has the advantage that can greatly contribute to increase the income of fruit farms.
