Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an apparatus and a method for dewatering and drying materials such as fresh edible plants and foods to be discarded, and in particular, after slicing a large amount of materials into fine powder, pressing and compressing to squeeze juices. Also, the present invention relates to an apparatus and a method for drying and reusing the residue as food, feed, or fertilizer.
[0002]
[Prior art]
In recent years, the amount of wounds and defective products of fruit and vegetables collected on farmland, wounds and unsold goods at collection markets, and leftover foods at the expiration date in hotels and restaurants are huge. Even if it is incinerated as industrial waste or landfilled at a landfill, there is a large amount of water in it, making it difficult to dispose of it. It is the current situation.
[0003]
At present, the company specializes in producing juices from fruits such as apples and tomatoes and vegetables such as cabbage and carrots in fresh edible plants for disposal. These companies slice about 500-600 kg of raw material, put it in a centrifuge, and squeeze out juices.Since a small amount of residue as marc is not feasible as a business to reuse, They pay a high cost and dispose of them at a processing company.
[0004]
[Problems to be solved by the invention]
Such a conventional apparatus usually has a main purpose function of producing juices by a centrifugal separator, so that a slicer and a dryer need to be provided separately. Therefore, the types of processing materials are limited, and the processing amount per batch is small. In addition, it takes a long time to squeeze out a large amount of juice, and the production efficiency of juice is poor. Furthermore, since the amount of residue produced is small, it is more inexpensive to pay disposal costs and dump and bury the waste than to dry it with a separate dryer. However, there is a problem that the work efficiency is inefficient.
[0005]
The present invention makes it possible to process a wide variety of waste foodstuffs, such as fruit and vegetables, coffee, tea spices, okara, unsalted cooked foods including livestock meat, and bento boxes, and is installed on the upper side of a common dewatering and drying device. The material that has been made into fine powder by the provided slicer is dropped into the housing by its own weight. The purpose is to shift to the drying process while being dewatered by stirring and compression, and the residue finally dried in the casing becomes an average of about 1/20 of the weight of the raw material before treatment, and the It is possible to feed and process materials sequentially in a short time without consideration. In addition, the material processing amount can be extremely large, for example, 13 to 16 tons can be processed per day, the residue can be sufficiently reused, food and food dumping can be largely eliminated, and environmental destruction can be prevented. It is intended for prevention.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, in the dewatering and drying apparatus of the present invention, a casing fixed to a machine frame is formed in a hopper shape from a top wall, both side walls having a lower portion inclined inward, and both end walls. A pair of screws are arranged and penetrated in parallel between the lower parts of the screws, and the screw end of the screw outside one end wall is provided with a drive unit via a support frame, and the other shaft end side is rotatably supported by the support frame. The perforated filter plate is disposed near the lower part of the rotation trajectory of the outer ends of the screw blades of both screws, and is attached to the lower edge of both walls. Further, a saturated steam of about 90 ° C. to 120 ° C. and a heated gas are jetted downward through a nozzle hole to a pair of pipes provided between the center portions of both end walls, so that sterilization, drainage, and drying are performed.
[0007]
When installing a filter tank and other attached equipment on the floor surface to remove the cage of the juice undiluted from the material when installing the above machine frame, it is mounted on the underframe, but when digging the floor surface No underframe is required.
[0008]
Collected edible plants, cooked materials, etc. are washed in advance with sterilized water and drained, then weighed, and a small amount of material is injected from the upper slicer opening at predetermined time intervals. You.
[0009]
The slicer has several rotating blades on the driven oblique shaft and a fixed blade inserted between the blades, and the material is cut to a diameter of about 5 mm to 10 mm on average and moves downward by its own weight, and a pair of blades in the housing Fall to Skrill. The casing has a hopper shape with a narrow bottom, and descends smoothly due to the weight of the material.
[0010]
Each of the pair of screeds is turned so as to turn clockwise or counterclockwise at an interval, and when one turns clockwise, the other turns counterclockwise, and when one turns counterclockwise, the other turns clockwise. Activate automatically. As a result, one side of the input upper material is offset toward the side wall, and the material on the other side is lowered to the screw portion. The reverse case also occurs, or the upper material rotates in an elliptical shape, and acts so that the entire material becomes smooth even if the material is thrown into the housing in one direction. Therefore, even if they are sequentially introduced into the housing of the apparatus in time sequence, they are uniformly stirred and dewatered by a pair of screws.
[0011]
The material that moves as it is pressed and squeezed by the screw is subjected to the pressure from the upper material, and is drained, filtered and reused as fresh juice. The dried residue whose weight and bulk have been reduced to about 1 can be immediately used as needed while storing it as a fresh food extender, functional material, livestock, farmed fish feed or fertilizer.
[0012]
An injection pipe having a through hole is disposed between the center portions of both end walls of the housing, and saturated steam supplied from a boiler connected to the injection pipe is injected, and the material which is constantly dewatered is heated to 40 ° C or more. Heating makes the screw softer, the rotation of the screw becomes better, power consumption is reduced, and liquid is rapidly drained. Further, the material is sterilized by heating, and is safely used as food or feed.
[0013]
When the liquid removing step is completed by the injection of the steam injection pipe, the heating gas is ejected from the injection pipe of the heating gas disposed above the injection pipe, and the process proceeds to the drying step. The heated gas is forcibly taken out of the already heated gas in the housing and heat-exchanged with the above-described saturated steam of the boiler. Since the liquid is sprayed, the water content of the liquid is heated to about 50 to 60%, and the dehydrated liquid is rapidly dried to a water content of 10 to 15%. The residue can be stored in a dry state for about 20 to 30 days without any change or decay, and used according to the purpose when necessary.
[0014]
The low-temperature vapor and superheated gas in the casing are forcibly sucked by a blower provided on the top wall of the casing via a suction pipe, and then the odor of the material itself or juice is absorbed by a known deodorizer. After removal, exhaust from the chimney. At this time, the raw material itself is fresh and has no putrid odor or bad odor, but since the raw material itself has an odor, consideration should be given not to affect the neighborhood and the environment.
[0015]
The materials are extremely diverse. In general, fruits and vegetables have a liquid content of about 92% to 96%, especially tomatoes reach 97%, and Chinese cabbage loses viscosity as dehydration is accelerated, so that the driving energy of the screw is reduced and the drying process time is shortened. In addition, the time for dehydration and drying varies depending on the liquid content, freshness, viscosity, and the like, and there is a difficulty in efficiently processing by automation of an electric control circuit.
[0016]
Most of the ingredients, such as tea flakes and coffee black tea (squeezed), contain less than 90% of the liquid (water) content. It is preferable to mix it with food. In addition, soybean milk is originally squeezed out of soy milk, it is not sticky, and if it is sliced finely, it can be quickly and quickly processed by deliquoring and drying. Therefore, it is used for many foodstuffs, feeds, and fertilizers. Can be
[0017]
Cooked foods such as lunches, etc. in the ingredients are mixed with meat and viscous cooked rice, and are mixed with dried okara, which contains a small amount of liquid. However, careful deliquescence is often used as feed for underwater fish farms.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be described based on examples with reference to the drawings.
If the raw material to be processed by the apparatus 1 in FIG. 1 is described as fresh cabbage waste, as a pretreatment, sodium hypochlorite is mixed to the extent that it is harmless to humans and animals, and it is immersed in a water tank made of a 200 PPM disinfectant and washed. I do. At this time, iron knives, scissors, etc. are attracted to the permanent magnets on the side walls, stainless steel materials and light metal appliances are settled by their own weight in the grooves on the bottom wall, and the dried residue that has been treated is used as human food when it is reused as food or feed. Avoid the danger of shortage as food. The cabbage waste sterilized and purified in this way is transferred to a perforated base plate and drained. The drained Chinese cabbage is put into a loading tank at a time of about 1 t at a time every 10 to 13 minutes, and the bottom thereof is transferred by a screw conveyor.
[0019]
The apparatus 1 for removing and drying the drained and transferred Chinese cabbage waste forms a machine frame 2 in the shape of a rectangular parallelepiped with a square steel pipe or a grooved steel material. A casing 8 made of a stainless steel plate is formed in the machine frame 2 in a hopper shape.

Thus, the screws 12a and 12b rotate the material 12 to 18 times per minute to dehydrate the material, depending on the type, freshness, and moisture content of the material.
[0022]
It is made of a stainless steel plate having a large number of through holes 25a and 25b having a diameter of about 3 mm, which are close to the lower half of the rotation trajectory of the outer edges of the blades 11a and 11b of the two screws 12a and 12b. Filter plates 26a and 26b having a W-shaped cross section are arranged, and attached to the lower edges of both side walls and both end walls. A filter plate 27 having both sides covering the inner edges of both filter plates is removably disposed in the notch at the center of the filter plates 26a and 26b, and is screwed to the lower edges of both side walls. I have. This is a dust discharge unit when the inside of the housing is washed by spraying water.
[0023]
FIG. 4 is an end view taken along the line AA in FIG. 2, and an opening 28 is provided in a corresponding portion of the screw blade provided on the lower extension 6 a of the end wall 6. Then, a lid 29 having a large number of through holes 25c covering the opening is disposed with the shafts 10a and 10b interposed. Locks 30 rotatably provided on the end wall 6a are locked to a plurality of receiving members of the lid 29, and the lid 29 is provided to be openable and closable.
[0024]
Since the particle material compressed and moved to the lid 29 by the screw is discharged so that the juice is scattered from the through hole 25c, the scattered juice is received by the stop plate 32 interposed on the support frame 17 side of the shafts 10a and 10b. , And falls into the lower guiding groove 33 b and is guided to the filtration tank 34. On the other hand, stirring rods 34a are provided radially on the shafts 10a and 10b adjacent to the end wall 6a to transfer the particle material in the lateral direction and reduce an excessive pressing load on the lid 29 to prevent accidental damage. To prevent.
[0025]
A large number of through holes 25d are provided in a portion corresponding to the blades 11a and 11b below the driving side end wall 5 shown in FIG. In order to cause the juice scattered outward from the through-hole 25d to fall into the lower guide groove 33a and flow down, a stop plate 35 is attached to the shafts 10a and 10b outside the end wall 5 as shown in FIGS. The upper end is attached to the end wall 5 while being interposed. Stirring rods 34b are provided in the radial direction on the shafts 10a and 10b close to the inner surface of the end wall 5, and the particle material compressed on the end wall 5 is moved laterally, so that the overload on the end wall 5 is reduced. Suppress to prevent damage.
[0026]
A slicer 36 is provided on one side of the housing top wall 7. In the slicer 36, the lower end of the inclined cylindrical housing 37 is opened at the top wall 7, and behind the rear end wall, a drive motor 38 and a drive shaft of a speed reducer are connected. The rotating shaft 39 is provided through both end walls of the cylindrical housing 37, and the rotating shaft 39 is provided with four cutting blades 40 in a plurality of housings at desired intervals in a direction perpendicular to the radial direction. Between the cutting blades 40, auxiliary cutting blades 41 disposed at upper and lower portions in the cylindrical housing are interposed. Then, the above-described draining material is sequentially injected into the input opening 42 provided at the upper end of the rear end of the cylindrical housing 37 for each desired amount measured by a screw conveyor, and crushed into an irregular shape having a diameter of about 5 to 10 mm. Meanwhile, it flows down by its own weight and falls into the housing. It is preferable that the slicer be closed with a damper or the like when not using a material.
[0027]
It is preferable that the pair of screws 12a and 12b for compressing and dewatering the material dropped to the lower part of the housing 8 heat the material by steam in order to operate efficiently and with low power. Therefore, saturated steam of 90 ° C. to 120 ° C. is discharged to the supply pipe 45 by the boiler 44 shown in FIG. 6, the solenoid valve 46 and the manual valve 47 are closed, and the solenoid valve 49 and the manual valve 50 of the branched bent pipe 48 are closed. Is opened and guided from the end wall 5 to the injection pipe 51 disposed in the housing. The steam injection pipe 51 has one through hole 52 at the center and two through holes at 20 cm intervals on both sides. The diameter of the through-hole 52 of the tube is 3 mm, and the diameter increases to about 5 mm toward the end. As a result, steam is uniformly injected downward from the entire area of the injection pipe, and the particle material is heated to a temperature of 40 ° C to 50 ° C and softened. The softened material is efficiently compressed and drained by the energy-saving power energy of the screw, and the material is further atomized by frictional force. And it is sterilized by this heating.
[0028]
When the water content of the liquid contained in the cabbage waste reaches 50 to 60% as a result of the material dewatering process, the dewatering process consisting of steam injection is stopped and switched to the drying process. In the drying process, as shown in FIG. 6, first, the solenoid valve 49 and the manual valve 50 provided on the bending pipe 48 are closed, and the solenoid valve 46 and the manual valve 47 of the supply pipe 45 are opened. On the other hand, the variable damper 57 of the flexible tube 56 connected to the housing top wall 7 and forcibly sucking the internal gas by the blower 55 is opened, and the internal gas is supplied to the heat exchanger 54. After the internal gas is heated to about 90 ° C. to 120 ° C. in the heat exchanger 54, the distal end of the flexible pipe 58 connected to the heat exchanger 54 is connected to the heated gas injection pipe 59 having one end provided on the end wall 5. Connected to. As the injection pipe 59 is moved from the base to the tip side, three through holes with a diameter of 3 mm are drilled at intervals of 20 cm in the lower part of the peripheral wall, and the fine material heated by the injection gas is heated to about 40 ° C. to 60 ° C. It dries out. When the drying process is performed for 6 hours to 8 hours, the water content becomes about 10 to 15%. Even if it is taken out and stored with this degree of drying, it does not rot for about 2 to 3 weeks. However, in order to dehydrate the water content to 10% or less, the operation efficiency of the present apparatus is improved by treating with a vacuum dryer provided separately.
[0029]
The juice filtered from the through holes of the filter plates 26a, 26b and the end walls 5 and 6 and the through hole of the lid 29 falls into the guide grooves 33a, 33b and flows into the filtration tank. In the filtration tank 34, several wire mesh plates having a smaller mesh diameter are sequentially arranged, and the cage is filtered and settled to produce a juice stock solution. On the other hand, when removing the residue from the housing after finishing the drying step, the guide 29 is pulled out beforehand, the lid 29 is opened and the screws 12a and 12b are operated to discharge the residue. Then, it is transferred to a desired packaging processing site by a belt conveyor 53 shown in FIG.
[0030]
At a desired position on the top wall 7 of the housing of the present apparatus, a blower with a motor 60 is disposed via a suction pipe 61 for gas containing steam in the housing. The blower 60 deodorizes various known odors through a flexible tube connected to the blower 60 and is exhausted from the chimney. The inside of the housing 8 is subjected to a liquid removal process while injecting saturated steam, and then further dried while supplying a heated gas. Since this steam is originally a raw material to be treated, there is no rotten odor or bad odor, but the odor inherent to the material is generated. This odor causes annoyance even if the apparatus is installed in a factory complex. Therefore, the odor is absorbed or eliminated by various known deodorizers from the blower 60 and then discharged from the chimney.
[0031]
In the step of dewatering and drying with hot air in the housing 8 of the apparatus, the movement of the material by the rotation of the pair of screws will be specifically described according to the automatic switching of the switch, timer, and forward / reverse converter of the control panel 31. . When the two screws 12a and 12b viewed from the driving side are rotated clockwise, the material of the two screw parts is compressed and narrowed by the driving end wall 5, moves, and rises while being drained. Then, all the material on the upper side moves to the side wall 3 side, and the upper material on the side wall 4 side descends and descends to the screw 12b. The operating time depends on the type of material, but is about 5 to 10 minutes for Chinese cabbage. Next, when the screw 12b rotates in the reverse direction, the material at that portion moves toward the end wall 6, and the material above the material moves toward both side walls, so that the central upper material descends. At the same time, the material above the screw 12b moves toward the end wall 6, but the material above the screw 12a tends to move toward the end wall 5, so that the whole rotates in a clockwise elliptical shape. This is completed in about 10 to 20 minutes. Next, when the screw 12a is rotated to the left and the screw 12b is rotated to the right, the material in the portion 12a is compressed and moved toward the end wall 6, and the material in the portion 12b is moved toward the end wall 5. The upper material tends to be moved toward the central axis of the housing, and the materials on both sides descend to 12a and 12b. Moreover, the upper material rotates leftward in an elliptical shape as a whole in the housing. This is also activated for about 5 to 10 minutes. Next, when both 12a and 12b are rotated counterclockwise, the material of both screw parts is compressed and moved toward the end wall 6, the upper material is moved to the side wall 4, and the material on the side wall 3 is lowered to the screw 12a. This operation time is about 5 to 10 minutes. Since the material moves in this way, even if the material is sequentially charged, the entire material is uniformly drained and dried.
[0032]
【The invention's effect】
The present invention is configured as described above, and has the following effects.
[0033]
A pair of rotating screws disposed at the bottom of the device casing have the same configuration and have been subjected to a drying process while generating a large amount of edible juice in the step of compressing and draining the finely divided material. , Extremely efficient processing can be performed.
[0034]
Since the cut particulate material to be put into the case is compressed by a screw, if it is weighed and put in sequence at intervals of time, it will quickly drain without regard to the case volume, and the weight of the material will also steep. Perish. Accordingly, a large amount of liquid can be removed in a short period of time, and a material of 14 to 16 tons per day can be processed only by predicting that the dry residue eventually becomes 1/2 of the housing volume. .
[0035]
In addition, if a draining material is put into the opening of the slicer provided on the top wall of the device housing, it will fall into the screw part at the bottom of the housing while being cut and crushed, and the juice generated by draining the liquid by the rotation of the screw will have its own weight. The water is filtered from the lower porous filter plate and flows down to produce a fresh beverage. In this way, a large amount of material can be automatically and efficiently processed at low cost by a flow-down method using its own weight.
[0036]
When the material is drained and dried to a water content of about 10 to 15%, it is stored as a powdery residue, and if necessary, it is used as a functional material for various foods and foods, a bulking material, a feed, and a fertilizer. It is now possible to reuse what was discarded as garbage. In this way, fresh garbage, such as unsold and uneaten garbage, has a great effect that, as the collection network is established, most of the garbage is reused and the environment is not destroyed.
