In general, meat processing means slaughtering livestock such as cows, pigs, chickens, and ducks and dividing them by site. In recent years, as a means of extending the distribution and preservation period of meat and increasing the added value of meat, Or in stores or on the market. As such, the process of frying the ingredients such as potatoes and sweet potatoes into oil is referred to as a hot water treatment process.

Vegetable cooking oil is widely used in such a hot water treatment process. Generally, vegetable cooking oil used in fryer is composed of unsaturated fatty acid, so oxidation is done well in a short time. Free radical is generated by heat, light ray and trace metal, Not only the phenomenon develops rapidly but also clusters (fat spheres) are generated by the heat of the high temperature in the oil itself, and the oil becomes turbid and the viscosity becomes high. In addition, the suspension by the foodstuffs is in oxidative contact with air and they are carbonized at high temperatures, accelerating the rancidity of the oil.

Repeated use of edible oil has resulted in the mixing of animal fats from foodstuffs, impurities, debris, fatty acids, oxides, etc., with the carbonization of deep-fried batter balls, making them impossible to reuse and contaminate large quantities of cooking oil . This is a waste of resources and acts as a cause of environmental pollution, so that more efficient treatment is required.

In Korean Patent Laid-Open Publication No. 10-2005-0101812 (published on October 25, 2005), oil for deep-frying in a frying machine for frying a confectioner is automatically circulated at a constant temperature through a filter unit and a heating device, Discloses an oil circulating system for a confectionery and a snack frying apparatus which is capable of filtering foreign matter and frying residues that can be contained in the frying apparatus and thereby obtaining high quality frying water as well as increasing efficiency of frying operation.

Korean Patent No. 10-0761971 (registered on September 19, 2007) has an ultrasonic oscillator and an ultrasonic decomposition chamber in a fryer to efficiently purify edible oil using ultrasonic vibration energy, A fryer is disclosed in which a cooking oil is passed through an oil refining chamber provided with a refining unit and the cooking oil can be reused in a clean and purified state.

As another example, Korean Patent No. 10-1522812 (registered on May 18, 2015) discloses a fryer having an automatic refining function capable of purifying and reusing various solid sludge suspensions and debris generated in oil have.

Although the above-described conventional technology discloses a device capable of partially refining oil and removing debris, it is not possible to continuously and automatically perform refining of oil and debris treatment during the course of the hot water process, .

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings showing embodiments of the waste cooking oil and the waste treatment method in the hot water treatment process according to the present invention.

1, the apparatus for hot water treatment according to the present invention comprises a fryer 1 for frying a food material supplied through a transfer means from frying oil such as edible oil, an oil-immersed state for transferring food ingredients in a fryer 1 , A conveyor belt 20, a sediment residue that removes debris such as debris or carbonized sediment that is splashed by the oil at a predetermined temperature while the foodstuff is moved on the conveyor belt in the fryer, from the bottom of the fryer, An oil filter unit 50 for removing carbide or debris floated in the oil generated during the frying of the ingredients in the fryer 1, an oil filter 50 for frying the ingredients in the fryer 1, And is prevented from being contaminated by animal fat and impurities of the food ingredients. And an oil purifier 70 for refining the oil while circulating the oil. The collecting cylinder 80 collects the coal and debris collected by the waste remover 30 and the oil filter 50 and the like and the compactor 90 compresses the residue of the collecting cylinder 80, The details of this will be described later.

As shown in the schematic cross-sectional view of Fig. 2, the fryer 1 has a rectangular cross-section and an elongated rectangular barrel, in which frying oil such as cooking oil is filled, and a conveyor belt 20, a conveyor belt 20 A conveyor belt 21 for collecting debris falling down during the frying of foodstuffs placed on the upper conveyor belt at the lower side of the fryer 1, Collecting grooves 22 formed in the width direction in the widthwise direction and collected by the waste conveyance conveyor belt 21 and collecting charcoal and debris collected in the collecting grooves by the waste collecting conveyor belt 21 And a conveyor belt 25 for transferring the waste residue.

The food material supplied by the conveyor belt 20 is introduced into the fryer 1 through the inlet of one side of the fryer and is moved to the opposite side by being carried on the conveyor belt 20 in the state of being immersed in the oil in the fryer 1 It is splashed by heated oil. The conveyor belt 20 then moves over the fryer and drops the frying product with a relatively lower product conveyor belt 24. On the underside of the product transport conveyor belt 24, a catch hopper 26 is disposed to collect oil and debris from the fried product.

When the food is transported in the oil-immersed state on the conveyor belt 20, when the food is splashed by the oil, the foreign matter buried in the foodstuff, the pieces of the frying piece coming off the foodstuff, the fat and the oil frying from the foodstuffs themselves, The residue is carbonized as the cluster (liposphere) is carbonized by the heat of the exhaust gas, and the residue must be removed in order to prevent the oil contamination from accelerating due to the carbonization of the residue.

To this end, while the foodstuff is moved on the conveyor belt 20 and fried, the coal and debris from the foodstuff fall off the lower conveyor belt 21, and the conveyor belt 21 moves the debris on the fryer bottom To the debris collecting groove 22 formed in the bottom plate 22a. As shown in FIG. 2, the collecting grooves 22 are formed in a widthwise shape on the bottom of the fryer. In the illustrated embodiment, three collecting grooves are formed. However, the collecting grooves 22 may be increased or decreased depending on the processing capacity of the fryer. have.

2, the conveyor belt 25 is disposed adjacent to the lower end of the conveyor belt 21 in the longitudinal direction of the collecting groove, . As a result, the debris that is conveyed by the conveyor belt 21 and drops into the collecting groove 22 falls onto the conveyor belt 25 provided in the collecting groove, and the conveyor belt 25 conveys the collected debris to the collecting groove 22, Is dropped onto the discharge conveyor belt 27 provided to extend outward from the end of the discharge conveyor belt 27 and discharged to the outside first waste collection container 28 by the discharge conveyor belt 27.

The conveyor belt 20 and the conveying conveyor belt 24 are all in the form of a perforated plate so that the waste residues or oil separated from the foodstuffs on the conveyor belt can fall below the conveyor belt, The debris conveying conveyor belt 25 and the discharging conveyor belt 27 are formed of a flat heat-resistant silicone material having no holes formed therein so as to simply convey the debris thereon.

In addition, since not only the debris generated during the frying of the food falls on the bottom of the fryer but also the relatively small sized debris may float in the oil, so as to prevent contamination of the oil, It is preferable to circulate the oil in the fryer 1 through the oil filter unit 50 with a pump in order to remove it.

4, the oil filter device 50 includes a housing 51 through which the oil of the fryer 1 is discharged and supplied, and a plurality of fine holes 52 in the housing, A drum 55 rotated by a motor 54 formed in a cylindrical shape and a discharge conveyor belt 56 disposed at a position higher than the oil level in the drum and discharging debris from the drum to the outside, And a second debris collection container 57 for collecting the debris conveyed from the discharge conveyor belt 56. The oil level in the housing is preferably kept lower than the rotational center axis 58 of the drum.

The drum 55 is arranged and rotated in a partially submerged state in the oil introduced into the housing 51 from the fryer 1 and the oil inside the drum is passed through the fine holes 52 of the rotating drum side wall, The drum hole 52 is formed by the air nozzles 55 disposed on the drum when the drum 50 is rotated together with the drum while being buried in the vicinity of the holes 52 at the inner side surface of the drum side wall without coming out through the holes of the drum. The debris adhering to the periphery of the drum holes is removed and transported to the outside over the discharge conveyor belt 56 disposed inside the drum and collected in the second debris collection container 57.

Then, the oil in which relatively large particle debris is removed from the drum is again passed through the paper filter 60, and relatively small particle size debris is removed and returned to the fryer 1. The paper filter 60 is configured to be partially immersed in the container 61 and the other portion to be inclined to extend over the container so as to rotate as the conveyor belt. As the paper filter 60 is rotated together with the conveyor belt, the oil is buried in the paper filter at the oil-immersed portion to move over the oil level, so that the oil is filtered and dropped to the container 61. The residue is transferred to the paper filter A scraper 64 is provided on the upper bottom surface of the paper filter 60 to scrape the residue on the paper filter to be discharged to the third debris collection container 65.

In this way, a certain portion of the oil in the fryer 1 is continuously circulated through the oil filter unit 50 and the paper filter 61 to remove charcoal and debris and then return to the fryer again, whereby the oil in the fryer is burnt, Can be minimized.

Nevertheless, the oil for frying the food such as edible oil contained in the fryer 1 is spoiled by oxidation due to heat and air contact. In order to reuse such oil, chemical refining by reduction reaction is performed in an oil purifier 70 configured as shown schematically in Fig. 5, while circulating oil in the fryer for chemical treatment.

To this end, the oil of the fryer is first transferred to the buffer tank 66 by a pump (not shown), and when the oil level of the buffer tank 66 is sensed by the sensor 67 sensing the high level, the pump operation is stopped And supplies a signal to the chemical oil purifier 70, which will be described later, to supply the oil, and to generate a signal to operate the pump when oil is not sensed by the low-level sensing sensor 68. Thus, the operation of the pump and the opening / closing of the buffer tank outlet valve are controlled by the signals from the sensors 67 and 68.

The oil purifier 70 includes a paper filter 71 and a reducing agent layer 72 of magnesium and silicon particles on the paper filter 71 so that the oxidized oil introduced from the buffer tank 66 flows into the reducing agent layer 72, The paper filter 71 disposed on the support plate is chemically reduced by the silicon particles, and the oil chemically reduced in the reducing agent layer is filtered and discharged through the magnesium and silicon particles, and the oil reduced and discharged in the oil purifier 70 The oil is discharged to the surge tank 75.

The surge tank 75 includes a high level sensor 76 and a low level sensor 77 below the high level sensor 76. When the oil level becomes a high level or more, the discharge valve of the surge tank is opened to supply oil to the fryer, And controls the discharge valve to be closed when the oil level becomes lower than the low level. Fresh oil is replenished in the surge tank 75. This is because the oil in the fryer is reduced by the amount of oil contained in the fryer 1 when the food is fried and discharged, So that the oil in the fryer 1 can be kept constant by supplementing the oil.

The oil chemically reduced in the oil purifier 70 is restored to a color and an acid value of less than 0.8. In this way, the oil recovered by the reduction can be maintained at a higher quality even on the basis of the acid value, and the oil in the fryer 1 is discarded by mixing the new oil with the reduced amount of oil contained in the food material frying in the surge tank And can be continuously used for the cooking of the food.

The coal and debris containing the oil contained in the catch piping 26, the first debris collection container 28, the second debris collection container 57 and the third debris collection container 65 are collected in the debris collection container 80 And then sent to the presser 90, so that the burnt powder and the residue are squeezed in the form of a cake, and the oil generated in this process is sent to the oil buffer tank 66 and fed to the fryer through the refiner. The residue cake can be used as feed.

When the food is transferred to the oil-immersed state carried on the conveyor belt 20, when the food is splashed by the oil, the foreign matter buried in the foodstuff, the pieces of the frying piece coming off the foodstuff, the fat and the oil for frying from the foodstuffs themselves, As the clusters (lipids) are carbonized by the heat, debris is generated. In order to prevent the contamination of the oil from being accelerated by the carbonization of the debris, the ingredients are moved on the conveyor belt 20 while being fried The charcoal and debris that fall off the foodstuffs of the food falls onto the lower conveyor belt 21 and the conveyor belt 21 drops the debris that has fallen thereon into the debris collecting grooves 22 formed on the bottom of the fryer 1, The groove 22 is formed on the bottom of the fryer 1 in the form of a ditch in the width direction,
The collecting groove 22 is provided with a conveying belt 25 for conveying debris in the longitudinal direction of the collecting groove 22 and disposed below the conveying belt 21 and conveyed by the conveying belt 21, The debris falling on the debris conveying belt 22 is dropped onto the debris conveying conveyor belt 25 provided in the collecting groove and the debris conveying conveyor belt 25 is moved upwardly from the end of the collecting groove 22 to the outside Is dropped onto a discharge conveyor belt 27 provided to be installed and discharged to the outside first waste collection container 28 by the discharge conveyor belt 27,
The conveyor belt 20 and the conveying conveyor belt 24 are all in the form of a perforated plate so that the waste residues or oil separated from the foodstuffs on the conveyor belt can fall below the conveyor belt, The debris conveying conveyor belt 25 and the discharging conveyor belt 27 are formed of a flat heat-resistant silicone material having no holes formed therein to simply convey the debris thereon,
Not only does the debris generated during the frying of the food fall on the bottom of the fryer, but relatively small sized debris floats in the oil. To prevent oil contamination, use a pump to remove the floating debris in the oil 1 circulates through the oil filter unit 50,
The oil filter device 50 includes a housing 51 to which oil of the fryer 1 is discharged and supplied and a motor 51 which is rotated by a motor 54 in a cylindrical shape in which a plurality of fine holes 52 are formed in the housing 51 And a discharge conveyor belt 56 for discharging debris discharged from the drum to the outside, which is disposed above the oil level in the drum. The waste conveyer belt 56 collects the debris conveyed from the discharge conveyor belt 56, And the oil level in the housing 51 is kept lower than the rotational center axis 58 of the drum,
The drum 55 is arranged and rotated in a partially submerged state in the oil introduced into the housing 51 from the fryer 1 and the oil inside the drum is passed through the fine holes 52 of the rotating drum side wall, The drum hole 52 is formed by the air nozzles 55 disposed on the drum when the drum 50 is rotated together with the drum while being buried in the vicinity of the holes 52 at the inner side surface of the drum side wall without coming out through the holes of the drum. The debris adhering to the periphery of the drum holes is removed and transported to the outside over the discharge conveyor belt 56 disposed inside the drum and collected in the second debris collection container 57,
Then, the oil having the relatively large particle debris removed from the drum 55 is again passed through the paper filter 60 to remove the debris of a relatively smaller particle size, return to the fryer 1,
The paper filter 60 is configured such that the paper filter 60 is partially rotated in the container 61 in which the partition wall is formed and the other portion is arranged to be inclined to extend over the container so as to rotate as the conveyor belt, The oil is filtered on the oil level and falls to the container 61.
