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

The apparatus for crushing and drying fruits and vegetables according to an embodiment of the present invention is intended to implement a system for crushing, drying, and temporarily storing discarded fruits and vegetables 31 such as melons, tangerines, tomatoes, and Chinese cabbages.

To this end, the apparatus for crushing and drying fruits and vegetables according to an embodiment of the present invention includes a two-stage housing and impellers 100 and 200 for sufficient drying of the crushed fruits and vegetables 31 as shown in FIGS. It can be configured to perform stirring and drying actions, and can be configured with a storage device 300 for receiving and storing the dried fruits and vegetables 31 and the mixed material 51.

4 shows the main configuration of the apparatus for crushing and drying fruits and vegetables 31 according to the present embodiment.

Since crushing and drying of fruits and vegetables 31 is possible using such a main configuration, the two-stage housing and impellers 100 and 200 illustrated in FIGS. It is composed of a single housing and impeller including a crushing and drying action of discarded fruits and vegetables (31).

In addition, as necessary, the crushing and drying apparatus of the present invention can process a large capacity by continuously connecting the basic configuration of FIG. Of course, it can be configured to be possible.

4, the basic configuration of the present invention is a housing 10 having a drying space 12 therein, an impeller 20 rotating in the drying space 12, and the drying space 12 A fruit and vegetable feeder 30 that supplies fruit and vegetable 31 to the drying space 12 from the upper side, and a drying space by crushing the supplied fruit and vegetable 31 installed between the fruit and vegetable feeder 30 and the drying space 12 12) and a crusher 40 for dropping, and a mixture feeder 50 for supplying the mixture 51 for moisture adsorption to the drying space 12 from the upper side of the drying space 12.

The housing 10 forms a drying space 12 accommodating the shredded fruits and vegetables 31 and the mixed material 51 therein and forms a wall to block it from the outside.

Since the impeller 20 is rotating inside the housing 10, a drying space 12 is formed to correspond to the rotating impeller 20. Accordingly, the lower part of the housing 10 is formed like a cylindrical lower part, and the lower part of the drying space 12 has a circular inner circumferential surface 13.

Accordingly, while the impeller 20 rotates, the end of the impeller 20 may rotate while contacting the circular inner circumferential surface 13, which is the inner surface of the lower part of the drying space 12.

On the upper side of the housing 10, a fruit and vegetable feeder 30, a crusher 40 and a mixed material feeder 50 are installed.

The fruit and vegetable feeder 30 supplies fruit and vegetables 31 from the upper side of the drying space 12 to the drying space 12, and may be melons, tangerines, tomatoes, etc. to be disposed of.

Fruits and vegetables 31 supplied by the fruit and vegetable feeder 30 are supplied to the drying space 12 in a state of being crushed by the crusher 40.

The crusher 40 is installed between the fruit and vegetable feeder 30 and the drying space 12 to crush the supplied fruit and vegetable 31 and drop them into the drying space 12, and a pair of crushing rollers interlocking with each other rotate while crushing the fruits and vegetables 31 entering between the pair of crushing rollers.

The mixed material feeder 50 is installed separately from the fruit and vegetable feeder 30 to drop the mixed material 51 into the drying space 12, and the mixed material 51 is for adsorbing the juice of the fruit and vegetable 31 and for moisture adsorption supplied with

Due to the supply of the mixed material 51, juice pools in the lower part of the drying space 12 or flows along the inner surface of the drying space 12 to alleviate the problem of debris sticking, and crushed fruits and vegetables 31 by the impeller 20 ) to facilitate stirring and drying.

Sawdust is most preferable as the mixture 51, and any environmentally friendly powder or chip-type material that can absorb moisture and be disposed of naturally can be used as the mixture 51, and the ratio of the supplied fruits and vegetables 31 and the mixture 51 is supplied by adjusting the set ratio.

A heater 18 is installed in the housing 10 to heat the fruits and vegetables 31 in contact with the circular inner circumferential surface 13 by heating the circular inner circumferential surface 13 .

The heater 18 may be a heating pipe through which high-temperature steam or hot water flows, or a heating wire that generates heat by electricity.

The crushed fruits and vegetables 31 are dried by raising the temperature of the circular inner circumferential surface 13 and the drying space 12 by the heat generated by the heater 18.

A temperature sensor 15 is installed on the upper part of the housing 10 to measure the temperature of the drying space 12 and control the heating state of the heater 18 by the controller.

In addition, an exhaust port 16 is installed at the top of the housing 10 so that gas generated during stirring and drying of the crushed fruits and vegetables 31 and the mixed material 51 in the drying space 12 can be discharged. (16) is connected to the deodorization filter to remove the odor and then discharge it into the atmosphere.

On the other hand, the impeller 20 is equipped with a plurality of blades 21 and rotates in the drying space 12 to stir the crushed fruits and vegetables 31 and the mixed material 51 and to move the wet fruits and vegetables 31 It acts as a drying agent.

The end of the blade 21 of the impeller 20 rotates while contacting the circular inner circumferential surface 13, so that the end of the blade 21 scrapes off debris attached to the circular inner circumferential surface 13.

To this end, it is preferable to install a brush 22 at the end of the wing 21 so that the impeller 20 rotates while the brush 22 contacts the circular inner circumferential surface 13.

The brush 22 may be a steel wire brush or a synthetic resin brush, and since it is flexible, it is easier to scrape off debris by contacting the circular inner circumferential surface 13.

An elastic plate such as a spatula may be installed at the end of the wing 21 instead of the brush 22 to rotate while contacting the circular inner surface, but when the elastic plate scrapes while contacting the circular inner circumferential surface 13, friction There may be a problem with loud and loud noises.

As above, if the brush 22 of the impeller 20 does not contact the circular inner circumferential surface 13 of the drying space 12 and there is no action to scrape the circular inner circumferential surface 13, discarded melons, tangerines, tomatoes, etc. The juice of the shredded fruits and vegetables 31 causes the debris to stick, and the solidified mass of FIG. 6 due to the debris is attached to the circular inner circumferential surface 13, which causes odor due to decay, occurrence of pests, and impeller 20 It causes problems such as interference with the operation of the dried fruits and vegetables 31 and discharge interference of the mixed material 51.

On the other hand, in the drying space 12, an inclined support plate 60 covering the impeller 20 from the upper side is installed, and the fruits and vegetables 31 crushed in the crusher 40 and the mixed material of the mixed material feeder 50 ( 51) falls on the upper surface of the support plate 60 and slides in the inclined direction of the support plate 60 to fall into the drying space 12.

When the fruit and vegetable 31 is crushed in the crusher 40, the support plate 60 protects the juice from falling directly to the main part of the impeller 20, so that the maintenance of the impeller 20 becomes complicated. is to relieve

4 and 5, the support plate 60 is inclined downward while going to the other end in a state in which one end is coupled to the horizontal hinge shaft 61, and the support plate 60 to limit the downward inclination angle of the support plate ( 60) is installed, and while the impeller 20 rotates, the end of the wing 21 periodically contacts the support plate 60 so that vibration occurs in the support plate 60.

Accordingly, the crushed fruits and vegetables 31 and the mixed material 51 that have fallen on the support plate 60 slide in an inclined direction by the vibration induction of the impeller 20 that periodically contacts them, eventually leading to a drying space 12 biased to one side It falls from one side of the position.

Among the positions of the upper surface of the support plate 60, the mixed material 51 falls higher than the fruits and vegetables 31 and slides in an oblique direction, and the crushed fruit and vegetable 31 falls on the sliding mixture 51, Let them slide together.

This causes the mixed material 51 such as sawdust to slide down the upper surface of the support plate 60 and support it like a carpet, and the crushed fruit and vegetable 31 with juice fall on the mixed material 51, and the juice of the fruit and vegetable 31 The mixed material 51 is sufficiently absorbed while coming down.

This action solves the problem that the juice flows down the upper surface of the support plate 60 and the juice directly falls into the drying space 12, and the mixed material 51 first contacts the juice and the fruits and vegetables 31 having the juice to sufficiently extract the juice. This is to make it fall into the drying space 12 in an adsorbed state.

In order to make this action more effective, the mixed material is spread on the upper surface of the supporting plate 60 between the position (A) where the mixed material 51 falls on the supporting plate 60 and the position where the crushed fruits and vegetables 31 fall (B) A bone 63 is formed.

The mixed material expansion trough 63 is a valley shape formed horizontally in the width direction of the support plate 60, and when the mixed material 51 that has fallen on the support plate 60 slides and meets the mixed material expansion valley 63, the mixed material expansion valley At (63), a temporary backlog is made.

During the stacking process, when the vibration of the support plate 60 by the impeller 20 occurs periodically, the mixed material 51 piled up in the mixed re-expanded valley 63 is horizontally spread along the mixed re-expanded valley 63 by vibration Then, when the mixed material 51 fills the mixed material 51 in the mixed material spread trough 63, sliding begins along the slope beyond the mixed material expanded trough 63.

Therefore, since the mixed material 51 sliding beyond the mixed re-expanded valley 63 moves downward along the mixed re-expanded valley 63 in a state where it is widely spread in the width direction along the mixed re-expanded valley 63, the periodic Inclined sliding is performed in a state like a wide spread carpet from the position passing the mixed re-expanded valley 63 by vibration.

Fruits and vegetables 31 having juice and juice fall on the mixed material 51 that is widely spread and slides like a carpet, and time for the mixed material 51 to sufficiently adsorb the juice may be given.

In addition, it is preferable that a retardation jaw 64 bent upward is formed at the end of the other free end of the support plate 60 .

The delay jaw 64 prevents the density of the mixture 51 spread on the support plate 60 from being lowered by the spread mixture 51 easily falling from the end of the support plate 60, and the fall of the mixture 51 is temporarily delayed so that the mixed material 51 maintains a thicker carpet shape on the support plate 60 to improve the action of receiving and adsorbing the juice and the crushed fruits and vegetables 31 with the juice.

On both sides of the base plate 60, side walls 66 and 67 are installed as shown in FIG. 5 so that the mixed material 51 slides smoothly in an inclined direction without flowing down in the lateral direction.

On the other hand, as shown in FIG. 4, a discharge port 71 that is always open is installed on the bottom of the lower part of the drying space 12, and a transfer screw 72 is positioned in the discharge port 71.

While the dried fruits and vegetables 31 are dried in the drying space 12, the discharge of the fruits and vegetables 31 and the mixed material 51 through the outlet 71 is blocked by the stopped transfer screw 72, and drying When the action is completed and the transfer screw 72 rotates, the fruits and vegetables 31 and the mixed material 51 are discharged through the discharge port 71.

By configuring the always-open outlet 71 as above, a separate opening and closing device for the outlet 71 is not required and the configuration can be simplified.

While drying is performed in the drying space 12 by the rotation of the impeller 20, the discharge of the crushed fruits and vegetables 31 and the mixed material 51 collected in the outlet 71 is blocked by the stopped transfer screw 72, but , Even if the brush 22 is scraped due to the high temperature drying action, some of the fruits and vegetables 31 and the mixed material 51 are collected in the outlet 71 and solidified, thereby blocking the outlet 71.

In order to solve this problem, the upper end of the transfer screw 72 is slightly protruded toward the drying space 12 through the open discharge port 71, and during the drying operation, the transfer screw 72 is periodically set. The controller acts as a control to repeat forward rotation and reverse rotation by a small amount of rotation.

Reference numeral 270, which has not been explained in FIG. 3, has a two-stage housing 10 and an impeller 20, so that the stirring and drying actions are performed in two stages, and the primary dried fruits and vegetables 31 and the mixed material 51 is a passage through which is moved for secondary drying.

Although the present invention exemplifies sawdust, etc. as a mixed material for mixing with fruits and vegetables, it may be configured to perform a drying operation by additionally introducing microorganisms, enzyme powder, and the like.

In this case, the temperature range of about 30 to 40 degrees in which microorganisms can be active is adjusted, and the crushed fruits and vegetables are stirred and dried with microbial materials, enzyme powder, etc. to promote decomposition, fermentation, and removal of odor, and can be used as feed, compost, etc. It can make it easier to use.

Although preferred embodiments of the present invention have been described above, the above embodiments are only one embodiment within the scope of the technical idea of the present invention, and for those skilled in the art, within the technical idea of the present invention Of course, other modified implementations are possible.
