Description

The scratch without chestnut exuviation method and its chestnut}

The present invention relates to a peeling method and a peeled chestnut of the chestnut with a thin, tasteless inner skin in the brown shell as a fruit of chestnut, and more specifically, using a dryer widely used in the market The purpose of the present invention is to provide a method of breaking the chestnut without scratches of the new concept that can be easily peeled from the ecology that has not been cut and the chestnuts peeled without scratches.

In order to eat chestnut, the fruit of chestnut, it is necessary to peel off the brown husk and the thin, salty cuticle located inside.

Conventional stripping method used a method of first peeling the brown outer skin with a knife and then processing the inner skin with a knife again. However, this stripping method has a disadvantage such as it takes a lot of time and is very unreasonable to process in large quantities. It was a manual form.

In recent years, the machining method has been proposed as a method to solve this problem.

Representative examples include chestnut peeling device of the Republic of Korea Patent Publication (B1) 10-1008930 (2011.01.17.), Shell peeling device of 10-0780677 (2007.11.30.), These are provided inside the cylinder A rotating plate rotated by a motor is provided, and a blade is attached to the rotating plate so that the shells of chestnuts (outer shells and inner shells) to be introduced can be peeled off.

Another example is to install a cut controller in the inner center of the outer cylinder, such as the night stripper of the Republic of Korea Patent Publication (A) 10-2002-0060022 (2002.07.16.) While driving the outer cylinder and the cut controller together, Peeled chestnut shells are being peeled off.

When peeling the shell of chestnut by the mechanical method as described above, there are many problems such as loss of kernel and damage of chestnut during processing.

Also, after peeling, much peeling of chestnut remained, so it was impossible to peel cleanly.

On the other hand, when the chestnut is eaten, unlike the above machining, the outer shell and the inner shell can be peeled together. Roasted chestnuts can be a hassle to bake before baking.

Hereinafter, an embodiment according to a method of peeling chestnuts without scratches using a dryer provided in the present invention will be described with reference to the accompanying drawings.

The present invention provides a method for peeling chestnuts without scratches with a thin, tasteless skin in the brown husks as a fruit of chestnut. It is characterized in that it can be easily removed from bad ecology.

In other words, in the present invention, the outer shell is rapidly dried and exposed to the outside air to continue to apply heat so that the crack occurs like a scratch on the outer shell due to the increase in the pressure of moisture contained in the kernel.

The dryer is controlled by a temperature controller for controlling the temperature of the upper end of the gas is installed in the upper air volume control opening, the back is provided with a discharge opening, the heater device capable of heating the interior is installed as shown in Figure 2 In order to open and close the opening and closing doors of the front to open the configuration that is widely used in the market (Korea Patent Registration No. 10-0569149) purchased and used, the detailed description of these dryers will be omitted. . It goes without saying that the dryer can be used in one of several different kinds.

The present invention by the method of 1) washing step, 2) primary drying step, 3) stripping step, 4) moisture replenishment step, 5) secondary drying step, 6) poor screening step and 7) aging step In the following, each step will be described in detail.

1) washing stage

Rinse chilled chestnuts in clean water to remove any moisture from the shells.

2) First drying step

The chestnuts are arranged and placed in the dryer so that holes are formed downward so that the air flow is not overlapped on the drying rack.

The dryer is provided with a flow rate control unit and an air outlet, the front and rear doors are installed and the heater device that can be heated to the interior is installed to buy one of the dryers widely used in the market.

As described above, after inputting the drying rack with short chestnuts to the dryer, open the air volume control unit so that the outside air is supplied, and then set the set temperature to 55 ° C. and heat 35 to 45 minutes to allow the internal temperature to be 35 to 40 ° C.

After heating as above, open and close the door, turn the door over in the state arranged in the dryer, close the door, open the air volume control a little more, and heat 35 ~ 45 minutes while maintaining the temperature of 35 ~ 40 ℃. The moisture contained in the outer shell is completely dried in a short time. It is preferable to heat the sweet chestnut type with a thin shell for 35-40 minutes, and to heat 40-45 minutes for the type of native chestnut with a thick shell.

At this time, the moisture contained in the kernel inside the inner shell increases the pressure in the inner shell by the temperature rise.

On the other hand, in the open state of the airflow control opening, it is preferable to open about 1/4 when opening the second time for the first heating, and the amount of inlet air may vary depending on the size of the airflow control opening, so it is adjusted to suit each machine. You will have to.

3) Peeling Step

As in the first drying step, the moisture contained in the outer shell is completely evaporated to keep the internal temperature of the dryer at 35 ~ 40 ℃ while keeping it dry. Hold for 40 minutes. At this time, it is ideal to open the gap between the gas and the door about 3 ~ 4㎝.

After 30 to 40 minutes as above, shake the drying rack and move the chestnut, and then heat for 30 to 40 minutes.

The outer shell is a dry ecology when the temperature is maintained at 30 to 35 ℃ while supplying the outside air as described above, and the inner kernels contain a large amount of moisture, so the pressure is increased due to the evaporation of moisture in a state surrounded by the inner shell. The cracking of the outer shell occurs, resulting in a crack in the outer shell and the inner shell. In this case, the cut may look like a cut made with a knife as shown in FIGS. 4 and 5.

On the other hand, if the inflow of the outside air is excessive in the stripping step, the shell temperature of the chestnut is rapidly cooled, and the temperature rise of the kernels decreases, so that the incidence of cracks of the shell and the inner shell is significantly reduced.

4) Water replenishment stage

As described above, when the stripping step is carried out, a considerable amount of moisture contained in the kernels is evaporated, thereby degrading the merchandise.

The present invention is to solve this problem to replenish the water to the kernel by immersing the sweet chestnut through the stripping step in cold water (drinking water) of 10 to 20 ℃ temperature for 25 to 40 minutes.

When the sweet chestnut, which has undergone the stripping step, is immersed in water as described above, the skin and kernels are supplied with moisture through the cracked portion as well as the outer shell.

5) Second drying stage

As in the water replenishment step, arrange the chestnuts supplemented with moisture so that they do not overlap with the drying rack, open the air volume control unit, and supply air to the dryer. Allow it to rise to dry the wet peeled husks and cuticles due to moisture replenishment.

At this time, the cut skin is dried and completely separated from the juicy kernels.

The open state of the air volume control opening is preferably about 1/4 open.

6) Bad selection stage

The defects are screened from the stripped balm, secondary dried as above.

In the screening work, it is usually necessary to select the one that does not have a slit. These are either rotten ecology or holes formed in the outer shell by insects.

7) Maturation stage

Poorly screened stripped chestnuts are lyophilized to a temperature of -2 to -3 degrees.

In the frozen state, the surface of the kernel containing water freezes and the volume increases finely. At this time, the outer shell and the inner shell are separated during thawing because they provide a function to further incise the open parts of the dry shell and the inner shell. It will help you.

As described above, the raw chestnut as shown in FIG. 2 is put into a drier, and the first drying step, the stripping step, the water replenishing step, and the second drying step are performed as shown in FIG. It is to form a crack on the outer shell and the inner shell.

In addition, the outer skin and the inner skin of the chestnut peeled without scratches processed by the method of the present invention can separate the kernels while the outer skin and the inner skin of the dried state is easily opened by holding the open portions with both hands as shown in FIG. 6. The kernel can be separated easily without the trouble of using a knife as in the prior art, and in particular, it is possible to erase the waste such as part of the kernel contained in the inner shell.

Example 1

Wash the short chestnuts stored in the refrigerator (about 120 ~ 130 tol; imported acid) in clean water, remove the water on the outer shell, and arrange the chestnuts so that they do not overlap on the drying rack. Hanyang Electric Machinery Co., Ltd. (Korean Patent No. 10-0569149) was put into the dryer produced.

At this time, the airflow regulator was opened by opening 1/4 to set the set temperature to 55 ℃.

Internal temperature was 34 degreeC in the state which passed 35 minutes after dryer operation. At this time, the door was opened and the door was closed while the chest was arranged on the drying rack, and the door was closed for about 40 minutes while the airflow control opening was opened by 1/2. At this time, it was found that the internal temperature was 37 ℃.

Next, while keeping the internal temperature of the dryer at 35 ° C., the opening and closing doors were slightly opened and maintained for 30 minutes while allowing the outside air to be naturally supplied through the edges of the doors.

As a result, a popping sound was heard inside the dryer, and as in FIG. 4 and FIG. 5, it looked like a scratch made with a knife every night.

After immersing the sweet chestnut in stripping step in cold water (drinking water) at 15 ℃ for 30 minutes, arrange the sweet chestnut so that it does not overlap on the drying rack, and open the airflow control unit 1/2 open to supply the outside air It was then heated for 90 minutes. At this time, the dryer internal temperature was 40 ° C.

After removing the defective product was lyophilized to a temperature of -2 ~ -3 degrees.

As a result, it was confirmed that the skin can be peeled without scratching by separating the outer shell and the inner shell with a hand as shown in FIG. 6.

In the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the protection scope of the present invention should not be limited to the described embodiments, but should be defined by equivalents as well as the following claims.
