2. Description of the Related Art A grease strap is provided in a drainage route of a store that uses a large amount of animal and vegetable oils for cooking, for example, a Chinese restaurant or a ramen restaurant, so that oils and fats that are mixed with the residual rice do not flow into the sewer. This will be described with reference to FIG. Reference numeral 30 denotes a washing tank (sink) installed in the kitchen, 31 denotes a grease strap, and the grease strap 3
Numeral 1 is connected to the washing tank 30 by a pipe 32. or,
The grease strap 31 is buried in the soil outside the kitchen (outside the building) and has a lid 33. 34 is a pipe for flowing water in the grease strap 31 to a sewer or a septic tank (not shown). is there. This pipe 34 is connected to the bottom of the grease strap 31, as is apparent from the figure.
The pipe 32 is connected to an upper part of the grease strap 31. As shown in the figure, the wastewater containing oils and fats to be put into the washing tank (sink) 30 of a Chinese restaurant or a ramen shop having the grease strap 31 is mixed with a liquid residue, soup, a dishwashing detergent, or the like. ing. Since all wastewater containing these fats and oils passes through the grease trap, they are separated into fats and oils in the grease trap 31, and only water is drained to the sewer. If the grease removal device is an existing grease strap 31, when the grease is removed or when a large amount of detergent is used, the following problems are likely to occur. For example, oils and fats adhere to the inner walls of the pipes 32 and 34, and the oils and fats are liable to be clogged, and the separation of the oils and fats by the grease strap does not work well. And contaminate rivers. Or, the grease collected on the top of the grease strap is
Unless the lid is opened and removed periodically with human power, the generated odor leaks to the outside and deteriorates the surrounding environment. Furthermore, since a large amount of water is taken at the same time as the oil and fat is periodically mechanically removed, there is a problem that it is difficult to treat the collected oil and fat. There is also a proposal to automate the operation of removing one or more oils and fats accumulated on the top of the grease strap, which is one of these problems, by periodically opening the lid with human power. Hereinafter, this proposal will be described with reference to FIG.
Reference numeral 35 denotes a washing tank (sink) installed in the kitchen. The cleaning tank 35 is supplied with the liquid slag described with reference to FIG. 36 is a grease strap (interceptor). The grease strap 36 has a separation tank 37. The grease strap 36 is buried in the soil outside the kitchen as shown in the figure. Thus, the washing tank 3
The oils and fats flowing together with the water (for cleaning) into the tank 5 enter the separation tank 37 from the inlet 39 of the grease trap 36 via the conduit 38. The oil or fat containing water that has been conducted is first filtered through a filter 40.
Is divided into fine solids and liquids. Then, in the separation tank 37, it is separated into water and oils and fats, and the oils and fats accumulate above the separation tank 37, and the water accumulates below it. The water accumulated below is drained from the drain 41 to the sewer. At this time,
The proposed grease trap 36 pumps oil and fat floating above the separation tank 37 by using a pump 42 instead of human power. The fats and oils pumped by the pump 42 are collected in a fat and oil collecting unit 43. As examples of the grease removal system or device provided with the grease straps 31 and 36 shown in FIGS. 13 and 14, JP-A-9-235776 and JP-A-7-2702 are known.
There is a gazette such as 84767. When the kitchen stand shown in FIG. 14 is installed in a kitchen or the like, the consistency of the members naturally becomes a problem. Therefore, the existing washing table (kitchen table with washing tank, sink with duct, work table with sink, Chinese range with sink, etc.) is, for example, 800-850 mm in height and 450-75 in depth.
Although it is unified as 0 mm, many models occur when height and width are variables. For this reason, for example, even if it is possible to technically incorporate an expensive oil and fat removing device into the washing stand, it may not be possible for the manufacturer to meet the demands of customers in terms of price. From this point, in the past, a simple kitchen stand or the like was mainly used and marketed.

[0003]

As described above, conventional kitchen stands alone do not have a grease removing device, and therefore, when they are washed in the sink of the washing stand, The problem of the grease trap described above is retained as it is. In addition, even if the kitchen stand maker has some unified dimensions, it is technically difficult to incorporate all expensive oil and fat removal equipment into each type of kitchen stand with different height and width dimensions. It was very difficult, if at all possible, to finance. On the other hand, it has been impossible for a user to purchase a washing table provided with a grease removing device or the like suitable for each kitchen. Further, there has been no device for collecting oils and fats contained in washing water and applying the collected oils to recycled resources.

[0004]

The present invention has been made to solve the above-mentioned problems. That is, a grease removing device is provided on a washing table provided with a washing tank for washing tableware and the like and a top plate forming an upper surface, and washing water containing the grease is introduced into the grease removing device to collect and remove the grease. Is what you do. Therefore, the dishwashers and the like dirty with grease are washed on the washing table (kitchen table with sink, sink with duct, work table with sink, cooking table with sink, Chinese cooker with sink, etc.) Even in the case of the present invention,
In the process of draining to the sewage, there is no need to say that the fats and oils directly flow into the sewage due to the intermediary of the fat and oil removal device, and the recovered fats and oils can be effectively used as recycled resources with low environmental impact. It can be used.
In addition, the flange of the top plate forming the upper surface of the washing table is fitted to the washing tank and is detachably assembled, so that the assembling standard is clear and the top plate can be easily attached and detached. Of course, all the water droplets splashed on the flange side of the top plate drop back to the cleaning tank side. Further, since the outer dimensions of the top plate mounted on the upper surface of the washing table are adapted to a kitchen table or the like installed adjacent to the washing table, a kitchen table with good consistency with the surroundings can be obtained. Things. Furthermore,
The grease removal device built into the washing table is composed of an oil skimmer that pumps grease collected on the upper surface of the separation tank that can be heated to a temperature that keeps grease in a liquid state, and an oil tank that collects grease captured by the oil skimmer. Comprising an exfoliating plate between the oil tank and the oil skimmer, guiding oil and fat separated from the oil skimmer to the oil tank via the separating plate, and setting the exfoliating plate to a solidification temperature of the oil and fat. The oil is easily recovered and removed from the washing water containing the oil and water that has flowed from the kitchen stand, and the purified water is of course washed away into the sewage. High oil content is a recyclable resource that can be used as livestock feed, industrial raw material, fertilizer or fuel.

1 is a diagram for explaining the collection of oil and fat in the auxiliary separator and the oil absorbing mat, and FIG. 12 is a diagram showing the auxiliary separator shown in FIG. 10 in detail. First, in FIG. 1, I is a washing table provided with the present invention. The washing table I includes a kitchen table, a work table or a Chinese cooker. As is apparent from the figure, the washing table I has a washing tank 1 dedicated to oils and fats for washing dishes, dishes and the like contaminated with oils and fats on the front side. This oil / fat cleaning tank 1 is a cleaning tank 1 dedicated to oil / fat of an oil / fat removing device 2 described later.
Reference numeral 12 denotes an oil tank that stores the oil and fat collected by the oil and fat removing device 2. FIG.
In the above, II is a top plate forming the upper surface of the washing table I, and the outer shape of the top plate II is made in a kitchen or the like in accordance with various kitchen tables and the like provided adjacent to the main washing table I. . That is, if this top plate is replaced, it can be adjusted to any adjacent kitchen table. For this reason, the top plate is mounted so as to be detachably mounted on the lower oil / fat removing device 2, and the outer dimensions do not always match those of the oil / fat removing device 2. In other words, this top plate II
Is the height of the kitchen table adjacent to the depth (for example, height 800-8
50 mm, depth 450-750 mm). Furthermore, the kitchen stand maker uses this top plate II
If only a few types are prepared, a kitchen table of consistent size can always be supplied for a kitchen of a normal size. This will be described in more detail. 2 is a grease removal device, II
Indicates a top plate. The top plate II has an outer peripheral frame IIa, and also has a flange portion IIb which enters the inside of the upper surface opening of the grease removing device 2. 2a is a supporting portion provided in the oil and fat removing device 2, and the supporting portion 2a is attached to the top plate.
The outer peripheral frame IIa of II is mounted on the grease removing device 2 so as to be mounted thereon. On the other hand, flange part IIb of top plate II
Is attached so as to just enter the inside of the upper opening of the oil and fat removing device 2. Reference numeral 12 denotes an oil tank, 15 denotes a duct to be described later, 9 denotes a drain port, and 9 denotes a drainage port. The cleaning tank 1 dedicated to oil and fat is provided via a top plate II such that its drain port 1a corresponds to the drain port 9 of the duct 15. It is assembled to the minute removing device 2. Next, the oil / fat removing stem (entire configuration) will be described with reference to FIG. Numeral 1 is a washing tank (sink) dedicated to fats and oils installed in a kitchen. In this washing tank (sink) 1, liquid rice such as ramen soup, ordinary soup, sauce and dressing is poured. Of course, the washing tank (sink) 1 dedicated to fats and oils is also provided with a snowboard (filter) not shown in the figure for preventing solids from flowing downstream. Reference numeral 2 denotes an oil / fat removing apparatus, into which the liquid residue left in the washing tank (sink) 1 dedicated to the oil / fat flows via a pipe (a duct 15 described later). In addition to the above-mentioned liquid waste, the wastewater containing grease from which dishes and cooking utensils have been removed flows into the grease removing device 2 via the duct 15 through a cleaning tank dedicated to grease. Reference numeral 5 denotes a washing tank (sink) in the kitchen. In this washing tank 5, wastewater that does not contain fats and oils such as tableware, soaking water for cooking utensils, wastewater for dishwashers, washing water for vegetables, etc. is supplied and passed through piping 6. Then, it is sent to the green strap (soshuki) 7. The grease strap 7 is generally employed, in which liquid wastewater other than oils and fats is caused to flow to the sewer 8, and the oils and fats are stored in the grease strap 7. The wastewater from which most of the oil and fat has been removed by the oil and fat removal device 2 described above flows through the pipe 3 and is connected to the pipe 6 that connects the cleaning tank 5 and the grease strap 7, and is connected via the pipe 6. It is electrically connected to the grease strap 7. The grease removing device 2 and the grease-only washing tank 1 are integrally formed.
It is attached to. By doing so, the people working in the Chinese restaurant routinely select the liquid residue containing oil and fat in the washing tank 1 dedicated to oil and fat, and the wastewater without oil and fat in the washing tank 5. Can be drained. As described above, the liquid residue containing oils and fats is drained to the sewer via the oil and fats removing device 2 and the existing grease trap or the like. As a result, the sewer does not become contaminated as in the related art, and the frequency of cleaning the grease strap itself can be greatly reduced.

Next, the overall configuration of the grease removing device 2 incorporated in the washing table I will be described with reference to FIG. It is preferable that the washing table having the grease removing device 2 is installed in a kitchen, but there is no problem even outside the kitchen (outside the building). or,
The height of the grease removing device 2 is made (800 to 850 mm) with the top plate II described above attached. Reference numeral 1 denotes a cleaning tank dedicated to fats and oils, and the cleaning tank 1 dedicated to fats and oils is used for cleaning dirt from liquid residue and dishes and cooking utensils. Reference numeral 10 denotes an oil skimmer, which causes a fat or oil to adhere (adsorb by hydrophobic interaction) to a metal belt described later, and
It works to pump more fats and oils. Reference numeral 12 denotes an oil tank where the oil and fat pumped by the oil skimmer 10 is temporarily stored. Since the fats and oils stored in the oil tank 12 are pure fats and oils containing no water, they can sufficiently withstand recycling. Reference numeral 11 denotes a separation tank, which will be described in detail below with reference to FIGS. In FIG. 9, the washing tank 1 dedicated to fats and oils has already been described,
In addition to the liquid remaining rice, etc., tableware 13 soiled with oils and fats is supplied and washed there. The supplied liquid waste or the water containing the grease after washing is discharged from the drain port 9 through the separation tank 11.
Is taken into the second separation tank 14 from the discharge port 16 via a duct 15 provided on the outer wall surface 14a of the second separation tank 14 formed by partitioning. The second separation tank 14 is independent of the separation tank 11 and is removably incorporated in the separation tank 11. Along with this, the cleaning tank 1 dedicated to fats and oils is of course also of a detachable built-in type.

Returning to FIG. 3, the water containing the fat and oil entering the second separation tank 14 from the discharge port 16 is guided by the guide plate 22 to guide the fat and oil of the liquid residue upward and the water downward. I will Reference numeral 10 denotes an oil skimmer which is one of means for removing oils and fats by an adsorption action. The oil skimmer 10 is driven by a drive motor 17. For example, a thin stainless steel belt 18 is rotated as shown in the figure, and oils and fats are pumped to the upper portion by utilizing an adsorption action such as a hydrophobic interaction with the belt. Therefore, the lower end of the belt 18 is immersed above the second separation tank 14 where the oils and fats accumulate. The oil and fat pumped by the belt 18 is separated from the belt 18 by a separation plate 19, and guided to the oil tank 12 via the auxiliary tank 20. The peeling plate 19a is provided so that the oils and fats adhered to the belt 18 are peeled before reaching the drive motor 17. The auxiliary tank 20 is provided in the oil tank 1.
2 only oils and fats are allowed to flow, and impurities including water etc.
Play the role of returning to. That is, as shown in the figure, this auxiliary tank 20 incorporates a double pipe separation device 20a,
Impurities such as water accumulated in the lower portion of the tank 20 return to the separation tank 14 as shown by arrows. In addition, an adsorption mat (not shown) is used as a means for removing the oil and fat by the adsorption action.
It can be used instead of this oil skimmer. Reference numeral 21 denotes a heater for heating the liquid stored in the second separation tank 14 to prevent solidification (increase in viscosity) of contained fats and oils. It is well known that, unlike mineral oils, animal and vegetable oils increase in viscosity at low temperatures. One of the features of the grease removing device of the present invention is that a heating means is provided to separate the grease using an oil absorbing mat (not shown) or an oil skimmer 10 without reducing the viscosity of grease even if the ambient temperature fluctuates. This means that oil and fat can be adsorbed or pumped from the tank. In order to perform efficient adsorption or the like, the temperature in the separation facility should be maintained at 50 ° C. or higher. From the viewpoint of temperature control, it is advantageous to separate the second separation tank 14 from the separation tank 11 and reduce the volume in consideration of power saving and the like. Further, the heater 21 naturally has a temperature control section 21a, and always keeps the second separation tank 14 in an optimal state.
Is controlling the temperature. The heater 21 has a large heat storage section 21b as shown in the figure. The function of the heat storage section 21b is to prevent the temperature in the separation tank 14 from locally increasing and to uniformly increase the liquid temperature of the entire separation tank 14. For this reason, the heat storage section 21b
Is made of a good heat conductor having an appropriate heat dissipation area and weight. This configuration also serves to prevent the abnormal temperature rise of the heater 21. When the heat storage section 21b is manufactured by casting aluminum, its surface may be covered with a corrosion-resistant material such as a stainless steel plate. Therefore, even if the animal and vegetable oils reach the solidification temperature at ambient temperature, the oils and fats do not solidify in the tank. This can also be said when the present grease removing device 2 is placed outside a building. Further, the auxiliary tank 20
Is positioned in the liquid in the separation tank 14,
Auxiliary tank 2 via the liquid stored and heated and stored
0 is heated so that this auxiliary tank 2
Oils and fats do not solidify within 0, and good fluidity is always maintained.

Reference numeral 23 denotes an auxiliary separator provided on the separation tank 11 side and comprising a double pipe and a triple pipe. This auxiliary separator 23 projects from the bottom of the separator 11, as shown in FIGS. 10 and 11, the outer tube 23a protrudes above the grease surface 24a, and the inner tube 23b is set to be equal to the water surface 24b. . And, as shown in FIG. 11, a water intake port 25 is provided below the water surface 24b in the outer tube 23a. Water is taken in from the upper end of the inner tube 23b. In the figure, reference numeral 26 denotes an oil absorbing mat, and the oil absorbing mat 26
The oil and fats that have not reached the auxiliary separator 23 and are not caught are finally disposed of. When the oil supply mat 26 is not used, if the oil and fat in this portion is periodically removed manually, the present apparatus can be efficiently used for a long period of time. Here, the details of the auxiliary separator 23 will be described with reference to FIGS. In FIG. 12, reference numeral 23 denotes an auxiliary separator. The auxiliary separator 23 is connected to a drain-side pipe 27, and traps A, B, C, etc., which support separation of water and oils and fats with a density difference inside. Are provided at a plurality of locations.
The auxiliary separator 23 is composed of a main pipe 23c formed of a triple pipe and a branch pipe 23d formed of a double pipe. A middle pipe 23c and a lower end of the branch pipe 23d are connected by a horizontal pipe 23e. are doing. 23f is a branch pipe provided in the middle of the horizontal pipe 23e. The separation of water and oil in the auxiliary separator 23 will be described below. Water from which most of the oils and fats have been removed by the oil skimmer 10 and the like, hereinafter referred to as primary treated water, is configured to be guided to the lower part of the separation tank 11 as shown by an arrow in FIG. The primary treated water proceeds as shown by the arrow and is guided upward by the inclined portion 23g of the branch pipe 23d formed of a double pipe. The function of the inclined portion 23g is to rectify the rising water flow as shown by the arrow, combine it with the rising force of the oil and fat due to buoyancy in the water surface direction, and accelerate the rising of the oil and fat as shown by the arrow. The water flow indicated by the arrow (10) taken in from the water intake port 25a has a reduced fat content than the primary treated water taken in as indicated by the arrow. This water is used as secondary treated water. The portion that supports the separation of water and oils before and after the water inlet 25a is a trap A. That is, water and fats and oils are separated by utilizing the density difference between fats and oils and water. The secondary treated water that has entered the branch pipe 23d from the water intake 25a flows along the outer periphery of the inner pipe almost directly to the water intake 25b of the inner pipe that is not provided facing the water intake 25a. The oils and fats also float on the water surface side in this process. A trap B is located before and after the water inlet 25b to support the separation of water and oil. In the secondary treated water that has entered the inner pipe of the double pipe 23d composed of the double pipe, the oil and fat rises as shown by the arrow (11), and the oil and fat further decreases. This water is called tertiary treated water. Then, as shown by the arrow (12), the tertiary treated water is sucked by the drainage power of the drain and descends, and reaches the branch pipe 23f via the horizontal pipe 23e. Also in this part, the oil and fat components
The water floats in the direction of the water surface in the pipe f, and the fat and oil content further decreases. This water is referred to as quaternary treated water. The quaternary treated water that has passed below the branch pipe 23f reaches the main pipe 23c. Even when the tertiary treated water passes through the horizontal pipe 23e, the horizontal pipe 2e
Since 3e is located below the water inlet 25b, the oil and fat floating on the branch pipe 23d is rarely caught. The quaternary treated water that has reached the trap C is divided into a stream containing a relatively large amount of fat and oil rising in the main pipe 23c indicated by an arrow (13) and a descending stream indicated by an arrow (14). It becomes the next treated water. What is particularly important is that a water inlet 25c provided on the pipe 27 side of the double pipe portion of the main pipe 23c formed of a triple pipe is provided below the trap C at a distance and a drop. By taking this distance sufficiently, the flow of the water shown by the arrow (14) and the fats and oils contained in the fifth treated water cannot fall, but rise to the water surface side as shown by the arrow (13). In other words, this effect is exhibited by providing the water inlet 25c near the bottom surface of the separation tank 11. On the other hand, an arrow (15) from the water intake 25c.
As shown in the figure, the fifth treated water that has entered the middle pipe of the main pipe 23c rises, and drains through the inner pipe opening 25d.
It overflows to the 7 side. Even at this time, in the trap D part,
The fats and oils float on the water surface as indicated by the arrow (16), and only the water whose fats and oils have been extremely reduced by separation overflows to the pipe 27 side as shown by the arrow (17). As described above, the auxiliary separator 23 allows the water flowing in the auxiliary separator 23 to pass through the trap portions provided at a plurality of locations based on the suction force of the water flowing down to the pipe 27, and the oil and fat floats in the water surface direction each time the auxiliary separator 23 passes. In addition, since the oils and fats are continuously removed from the water stream, it has a function of flowing purified water to the downstream side. The auxiliary separator 2
3 is provided with lids 23h and 23i at the tops of the main pipe and the branch pipes for the purpose of improving appearance, silencing, deodorizing, and the like. Lid 23h, 2
The fats and oils that accumulate directly below 3i may be removed occasionally by removing the lid and using an oil-absorbing mat or the like. Returning to FIG.
Reference numeral 27 denotes a pipe for guiding the water separated by the auxiliary separator 23 to the grease trap 7 (so-called collector) described with reference to FIG. As described above, the wastewater from the present oil / fat removing device 2 is not directly discharged to the sewer but is discharged to the existing grease trap 7 (see FIG. 5). Reference numeral 28 denotes a cleaning drain cap provided at the bottom of the separation tank 11. When cleaning the inside of the tank, the cleaning drain cap 28 is removed, and all the water in the separation tank 11 is discharged to the outside of the tank. Cleaning tank 9 for oils and fats, oil skimmer 1
0, the oil tank 12, the second separation tank 14, the heater 21 and the like are sequentially removed and washed. Needless to say, these cleaning waters are drained to the outside after being guided to the grease trap 7. Also, as shown in FIG.
A heat conductive plate 19b is attached to the peeling plate 19,
As is clear from FIGS. 3 and 6,
One end is closely attached so as to cover the entire back side of the peeling plate 19, and the other end is immersed in the auxiliary tank 20 heated by the heat storage liquid in the separation tank 14. In other words, the heat of the liquid stored in the separation tank 14 heated to about 50 ° C. or more is transferred to heat the peeling plate 19, so that the oil or fat flowing on the peeling plate 19 becomes To prevent solidification. If the heating means is not provided, the fats and oils are likely to be solidified in winter when the outside air temperature drops and immediately before the operation of the present fat and oil separation and removal apparatus ends. In order to prevent this, the heat stored in the liquid stored in the separation tank 14 is transferred via the heat conductive plate 19b to heat the peeling plate 19. Thus, the heat conducting plate 19b may be formed of a material having good heat conduction and corrosion resistance. Further, the reason why the entire peeling plate 19 is covered is that when the peeling plate 19 is made of a material having poor heat conductivity such as stainless steel, the whole is heated for the purpose of promoting heat conduction. FIG. 7 shows an embodiment different from FIG. 6, in which the entire back surface of the peeling plate 19 is heated by a heater. In this case, the temperature of the peeling plate 19 can be controlled to 50 ° C. or more by controlling the input of the electric heater 19c without using any special means. The electric heater 19c shown in FIG. 8 is used when the heat conducting plate 19b shown in FIG. 6 has insufficient heat transfer efficiency and the release plate 19 cannot be heated to 50 ° C. or more.
5 shows an example in which heating is performed by using the method shown in FIG. Further, although not shown in the drawings, the present invention has been described in detail with an example in which the peeling plate 19 is heated. However, the present invention is also applicable to the auxiliary tank 20 located downstream of the peeling plate 19, and of course. If necessary, this tank is also heated by various means.
By doing so, the oils and fats separated from the oil skimmer 10 are guided in a liquid state with good fluidity to the oil tank 12 via the peeling plate 19 and the auxiliary tank 20, and solidified and deposited on the way. It does not stop the flow. The supply of the cleaning water containing oils and fats to the washing table I with the top plate is not shown in the figure, but if a height difference is set and a transfer means such as a pump is used, a cleaning tank dedicated to oils and fats and an oil and fat removing device are used. Can also be placed in a remote location. Next, the grease removing step in the grease removing device 2 having such a configuration will be described with reference to FIG.
The fats and oils pass through the drain port 9a as shown by the arrow, and
Is introduced into the second separation tank 14 from a discharge port 16 as indicated by an arrow via a duct 15 provided in the second separation tank 14. The flow of the wastewater containing oils and fats entering the second separation tank 14 is rectified by the guide plate 22, and the water has a lower buoyancy due to the rising water flow and the density difference as shown by the arrow, as shown by the arrow. The resultant oil and fat that floats above the separation tank 14 as a result of the combined force is floated on the surface while being kept in a fluidized state without solidification due to the fact that the second separation tank 14 is heated by the heater 21 from the beginning. I have. The oils and fats floating on the surface are pumped up by the oil skimmer 10 or the like. The pumped oil and fat is stored in the oil tank 12 via the peeling plate 19 and the auxiliary tank 20, and is recycled. On the other hand, the primary treated water with reduced fat content flows along the bottom of the guide plate 22 as shown by the arrow as shown by the arrow, and further flows into the second separation tank 14 shown by the arrow.
Of the wastewater that has reached the separation tank 11, which further reaches the separation tank 11,
The oils and fats (the oils and fats that could not be removed by the oil skimmer 10) float on the water surface due to the buoyancy due to the density difference, and the oil absorbing mat 2
6 is adsorbed. The treated water from which the fats and oils have been successively separated and removed enters the double pipe of the auxiliary separator 23 via the path shown by the arrow and arrow (10), enters the pipe 27 from the upper end of the inner pipe 23b via the conduit, and the grease trap 7. (See FIG. 5). By installing the grease removal device 2 in front of the grease strap 7 in this manner, contamination of the grease strap 7 can be suppressed. Also, as shown in FIG.
Since the present grease removing apparatus 2 includes the casters 29, the washing table with the top plate of the present invention can be easily moved not only in the kitchen but also outside the building. In other words, the kitchen table with the top plate can be moved to an easy-to-use place in a store or the like and used. Further, since the release plate 19 is heated to a temperature at which the oil and fat maintain fluidity, the oil and fat separated from the oil skimmer 10 may solidify in the process of flowing through the release plate 19 and adhere to the release plate 19. Absent. Once the oils and fats solidify and accumulate on the peeling plate 19 once, the solidified oils and fats become nuclei and solidification grows and is promoted. In consideration of this point, the peeling plate 19 is always 50 ° C. regardless of the ambient temperature.
The above obstacle can be prevented by heating as described above. The present invention has realized this. Another feature of the present invention is that the second separation tank 14, the oil skimmer 10, the oil tank 12, the auxiliary tank 20, the heating heater 21, the auxiliary separator 23, etc. can be easily attached and detached based on the separation tank 11. By being made, it is excellent in handling, operability, economy and the like.
