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

Chestnut shell discharged from the processing plant contains about 50 to 60% of moisture, so it is easy to denature when stored at room temperature for a long time. Therefore, it should be dried and used as soon as necessary while drying or freezing.

The drying temperature affects the whiteness of the product, so drying at the lowest possible temperature is recommended, but drying time is increased.

The dried shells thus spaced the chestnut flesh through the coarse grinder.

At this time, the finely ground chestnut powder is finely pulverized in the process of separating from the shell, so it is important to grind the granules as homogeneous as possible.

When crushed into granules like this, chestnut flesh and skin are separated and mixed.

In this state, the shell and chestnut are separated using a wind-powered separator, and it is better to separate them by size to increase the separation effect.

When separated into sizes, each placed in a wind turbine, the light shell flies away and the chestnut flesh is wrapped up nearby.

The chestnuts separated for each size are mixed and sent to the mill. The chestnut powder, which has been ground in a US mill, is shipped as a product.

(Example 1)

In the manufacture of chestnut powder, it was designed to manufacture or manufacture various devices required for each process, and the process was expected to be expensive.

In particular, in order to maintain the operator's environment comfortably during the operation of the process, it is expected that sealing is required where the powder is easily scattered among the apparatuses entering each process, and the process diagram of the entire process designed is shown in FIG. 1.

It is discarded during processing, and since the chestnut husk contains moisture, it is possible to produce chestnut powder in fresher condition by using dried or refrigerated chestnut husk as raw material in the field. Therefore, if moisture-containing chestnut husks are collected, they are first stored in a frozen state and added to the powdering process.

As shown in Fig. 1, the chestnut shell dried in the drying apparatus 1 is subjected to a coarse grinding process (4), a three-stage vibrating body separating process (6), a wind power sorting process (12), an uncrushed process (13), and a shipping process ( 14) and the main supplements in the design of each process are as follows.

In the dryer (1), chestnut husks are collected in a state containing 50 to 60% of moisture, and stored in a frozen state, and put into a process when necessary in order to powder into an existing raw material supply and demand pattern.

The drying temperature was experimentally proved that the whiteness of the chestnut powder produced was improved as the drying temperature was as low as possible, and the whiteness of the chestnut powder produced was significantly decreased at a temperature higher than 80 ° C.

Chestnut husk inlet (2) can be put directly into the dried chestnut shell, and dried in the dryer was allowed to flow along the slope of the discharge plate to be stored to some extent.

The pocket conveyor (3) is installed in front of the wind sorter for the purpose of conveying the chestnut shells stored in the inlet (2) to the tank mill, the conveyor in front of the tank mill and for the purpose of transporting the crude grinding particles separated by size. It was installed to move the target material in the vertical direction to induce the flow of the process conveniently.

The dried chestnut hulls and sieves separated by size in each storage tank were fed to the tank mill and wind sorter at a rate of 20 l / min.

The coarse grinder 4 can be referred to as a shell relaxation process, and the chestnut shell and chestnut flesh are squeezed in order to further advance the gap due to different shrinkage rates during the drying process.

During this process, the chestnut peels in about 2 to 5 mm, and the chestnut shell and chestnut flesh are separated.

If the classifier 5 does not supply a certain amount to the grinder or sorter correctly, the classifier should be installed because mechanical bunching or grinding or sorting did not occur well during the grinding or sorting process. Use a type air gap roller or a brush type roller to supply a fixed quantity.

The feed object flowed from the top into the rotating honeycomb pores or into the brush, and the chestnut husks were allowed to fall to the bottom when turned downward by rotation.

Brush type classifiers are more quantitative in fixed speed than honeycomb type, and the production cost is cheaper and the problem frequency is less frequent. Therefore, it is better to introduce the brush type classifier into the process.

The windscreening method is used to separate chestnut shells and chestnuts broken into various particle sizes in the crude grinding process, and the sieves are separated to have a relatively similar particle size distribution in order to increase the efficiency of windscreening.

This sieve separator (6) is composed of three stages and separates and collects what has passed through 5, 10, and 15 mesh sieves from the top. Separation conditions were derived.

Storage tanks (7), (8), (9) and (10) should pass through 5, 10, and 15 meshes during the sieve separation in their respective storage tanks, opening the outlets as necessary and sending them to the wind selector.

The discharge switching lever 11 manually controls the closing and opening of the discharge port at the bottom of the storage tanks 7, 8, 9 and 10, and allows the opening and closing according to the situation of each storage tank.

The wind sorter 12 separates shells and chestnuts using the force of the wind, and the wind volume and wind speed of the sorting process are adjusted according to the size of the incoming particles.

The fine grinder 13 grinds the wind-selected chestnut meat into chestnut powder, and the size of the powder may be varied depending on the use.

Chestnut powder metering and packaging device 14 was to be weighed and packaged in the required amount for shipping the produced chestnut powder.

The vertical dust collector 15 is a device for removing dust scattered from a wind power sorter and is designed to remove dust of relatively large size by installing a cloth of about 20 mesh in a vertical direction.

The horizontal dust collector 16 is a device for removing fine particles in the primary dust collected in the vertical dust collector 15 so as to use a bag filter type dust collector in order to smoothly remove dust. Designed.

The air discharger 17 is forced through a vertical dust collector 15 and a horizontal dust collector 16, so that a considerable amount of pressure loss occurs, thereby making it difficult to move the discharged air.

Disposable inner shell storage tank (18) was designed to be stored in order to periodically discharge the discarded shell after recovering the chestnut flesh and the capacity was designed to about 500ℓ.

(Example 2)

In the second embodiment of the present invention, the process of the first half is the same as in the first embodiment. In the first embodiment, the ground chestnut and chestnut shell are separated by a wind screening process. Since the sedimentation process is carried out in the water, which separates the chestnuts that settle down and settles down, it is required to add a drying process to remove moisture.

In this way, the crude dried chestnut powder separated and dried is transferred to the fine grinder 13 in the first step, and then weighed and packaged in an amount necessary for shipment from the weighing and packing device 14 of the uncrushed chestnut powder.

Chestnut powder powder prepared by the above apparatus and process will contain about 5% of undivided cuticle powder, but if it is added as a trace amount of tannin, it will act as a pharmacological effect rather than harmful to human body. It is known to be.

The present invention as described above, the chestnut shell dried in the drying apparatus, the night shredding process, three-stage vibrating separation process, wind sorting process or underwater sedimentation separation process + drying process, uncrushed process, during the shipping process discarded chestnuts Powdered chestnuts attached to the inner skin of powder is separated and recovered, which is used as a variety of food raw materials such as bakery, confectionery, baby food, and has a very excellent effect of preventing waste of food resources and contributing to recycling of resources.
