[0005] The disadvantage of the prior art is that, in order to make full use of the fumigation space, a plurality of steaming plates with steaming holes are usually arranged in the fumigation space. However, since the food is usually placed directly or indirectly on the steaming plates, most of the steaming holes will be blocked, hindering the upward movement of the steam, making the fumigation effect of the bottom of the food lower than that of other parts. Moreover, the multi-layer blocked steaming plates will also affect the circulation of the steam. Summary of the invention

[0006] The object of the present invention is to provide a fumigation oven for food processing to solve the above-mentioned deficiencies in the prior art.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] like Figure 1-10 As shown, a fumigation furnace for food processing provided by an embodiment of the present invention comprises a furnace body 1, a sealing door 11 is hingedly connected to the front end of the furnace body 1, a plurality of trays 2 are installed in the furnace body 1, a plurality of through holes 21 are penetrated on the trays 2, a moving part 22 is slidably installed in the trays 2, a plurality of vents 23 corresponding to the through holes 21 are installed on the moving part 22, a through opening 231 is opened on the side wall of the vents 23, and a driving unit 24 is also installed on the trays 2; when the furnace body 1 is closed, the sealing door 11 squeezes the driving unit 24 and forces the vents 23 to move upward through the through holes 21.

[0034] Specifically in this embodiment, a fumigation chamber is formed inside the furnace body 1, the furnace body 1 is mainly made of stainless steel material, the front end of the furnace body 1 is in an open state, a steam generator (not shown in the figure) is arranged at the bottom of the fumigation chamber, the steam generator is used to heat water into steam, the steam generator is a prior art, no further description is given, a steam circulation system is also arranged in the fumigation chamber, the steam circulation system is used to re-introduce the steam output from the top of the fumigation chamber to the bottom of the fumigation chamber, so as to make full use of the steam, the steam circulation system is also a prior art, no further description is given; the main body of the sealing door 11 is a square plate-like structure, the furnace A locking mechanism is installed on the side wall of the body 1. When the sealing door 11 is rotated to fit against the front end of the furnace body 1, the position of the sealing door 11 is locked by the locking mechanism. This is a prior art and will not be described in detail. The receiving tray 2 is located in the fumigation chamber and is arranged in sequence from top to bottom. The number of the receiving trays 2 is at least three. It should be noted that in this embodiment, the receiving tray 2 needs to have a certain thickness to carry food of a specific weight, such as stacked rice dumplings, meat, agricultural and sideline products or other canned products, to avoid deformation of the receiving tray 2 due to overweight food, which will also make the through hole 21 have a certain thickness. It should be noted that in this embodiment, the "food" should not be placed in the bowl. This is because the vent 23 is easily pushed out and causes the bowl to tip over. Of course, this can be solved by placing the bowl in a specific position (such as making the vent 23 evenly distributed under the bowl), which will not be elaborated here. A mounting groove 25 is formed inside the tray 2, and the tray 2 is horizontally arranged in the fumigation chamber. The through hole 21 is preferably a cylindrical hole, which is mainly used for the flow of steam. The moving member 22 is plate-shaped and is slidably installed in the mounting groove 25 along the vertical direction. There is a certain distance between the moving member 22 and the top wall of the mounting groove 25. The mounting groove 25 is vertically spaced. The height space is the vertical moving space of the moving part 22; the vent cylinder 23 is a cylindrical structure with a sealed upper end, and the space inside the vent cylinder 23 is a steam passage space, defined as a steam ventilation space, and the vent cylinder 23 is slidably installed in the through hole 21 so that the moving part 22 can only slide in the vertical direction. The number of the openings 231 is preferably two and symmetrically arranged, and the steam ventilation space is connected to the openings 231. When the vent cylinder 23 is pushed out, steam enters the steam ventilation space from the bottom end of the vent cylinder 23 and is discharged from the openings 231; the driving unit 24 is located between the moving part 22 and the bottom wall of the mounting groove 25, and is mainly used to receive the extrusion force of the sealing door 11 and drive the vent cylinder 23 to be pushed out.

[0035] In this embodiment, the ventilator 23 has two working states, namely, a flush state and an ejected state, and the initial state is the flush state; when the fumigation furnace is stopped and the sealing door 11 is opened, the ventilator 23 is in a flush state, and the upper end of the ventilator 23 and the upper end of the through hole 21 are in the same horizontal plane. The ventilator 23 seals the through hole 21, which is very necessary. On the one hand, it can prevent dust from entering the ventilator 23 from above when the fumigation furnace is stopped. On the other hand, it can also make the upper end of the tray 2 form a complete horizontal plane in the initial state, which is convenient for the tray 2 to seal. When the food is in the ejection state, the food is placed on the tray 2 and the sealing door 11 is closed. At this time, the driving unit 24 presses the movable member 22 to move vertically upward and drives the vent cylinder 23 to eject the through hole 21. The height of the upper end of the vent cylinder 23 is greater than the height of the upper end of the through hole 21. At this time, the steam enters the steam ventilation space from the bottom of the vent cylinder 23 and is discharged from the through hole 231. In this way, even if the food is placed on the through hole 21, the upward movement of the steam will not be hindered. In addition to ensuring the fumigation effect at the bottom of the food, it can also ensure that the steam can be smoothly recycled through the steam circulation system.

[0036] Obviously, in another embodiment, the movement of the movable member 22 can be controlled by an electric push rod. This solution is easy to think of, but it requires the provision of an additional driving source and other structures, so it will not be described in detail.

[0037] In another embodiment provided by the present invention, a plurality of limit brackets 12 corresponding to the receiving trays 2 are installed in the furnace body 1, and each receiving tray 2 corresponds to two limit brackets 12, and the two limit brackets 12 are in the same horizontal plane. The receiving tray 2 is slidably installed on the limit brackets 12, and the sliding direction of the receiving tray 2 is horizontal sliding, that is, the receiving tray 2 is slidably installed between the two limit brackets 12, and the limit brackets 12 are located below the corresponding receiving tray 2. When working, the receiving tray 2 can be pulled out first, so that it slides outward on the limit brackets 12, and then food is put in or taken out.

[0038] In another embodiment provided by the present invention, a mounting groove 25 is opened in the supporting tray 2, and the front end of the mounting groove 25 is connected to the outside. The mounting groove 25 divides the through hole 21 into a first hole at the top and a second hole at the bottom. The upper end of the ventilator 23 is slidably installed in the first hole, and the lower end of the ventilator 23 is slidably installed in the second hole. The movable member 22 is slidably installed in the mounting groove 25 along the vertical direction, and there is a certain distance between the upper end of the movable member 22 and the top wall of the mounting groove 25, so that the movable member 22 has space to slide upward.

[0039] In another embodiment provided by the present invention, the upper end of the vent cylinder 23 is in a sealed state, and the lower end of the vent cylinder 23 is in an open state. The diameter of the vent cylinder 23 is equal to the diameter of the through hole 21. When the upper end of the vent cylinder 23 and the upper end of the through hole 21 are on the same horizontal plane, the upper end of the supporting tray 2 forms a complete plane; in the initial state (that is, the flush state), the upper end of the vent cylinder 23 and the upper end of the through hole 21 are on the same horizontal plane, and the lower end of the vent cylinder 23 penetrates the supporting tray 2 and extends to the bottom of the supporting tray 2. When the vent cylinder 23 is ejected, the lower end of the vent cylinder 23 moves upward and is retracted to the supporting tray 2.

[0040] In another embodiment provided by the present invention, the driving unit 24 includes an elastic limiting rod 241 arranged at one end of the mounting groove 25 away from the sealing door 11, a sliding rod 242 is fixedly connected to the movable end of the elastic limiting rod 241, the sliding rod 242 is located between the bottom wall of the mounting groove 25 and the moving member 22, a trapezoidal extrusion block 243 is formed at the upper end of the sliding rod 242, and a driving block 244 is formed below the moving member 22. When in a flush state, the lower end of the driving block 244 is attached to the upper end surface of the sliding rod 242. The trapezoidal extrusion block 243 and the driving block 244 are correspondingly arranged, and the two form a wedge-shaped extrusion fit. When the sliding rod 242 slides into the mounting groove 25, the trapezoidal extrusion block 243 can squeeze the driving block 244 to move upward, that is, the driving block 244 is in the movement direction of the trapezoidal extrusion block 243; the sliding rod 242 is correspondingly arranged with the sealing door 11. When the sealing door 11 rotates and fits the front end of the furnace body 1, the sealing door 11 squeezes the sliding rod 242 to move into the mounting groove 25. The front end of the sliding rod 242 extends outside the mounting groove 25, so that the sliding rod 242 can be squeezed inward when the sealing door 11 is closed. Specifically, during operation, after the food is placed, the sealing door 11 is closed. At this time, the sealing door 11 squeezes the sliding rod 242 to move inward and synchronously squeezes the elastic limiting rod 241. The movement of the sliding rod 242 drives the trapezoidal extrusion block 243 to move inward synchronously. At this time, the trapezoidal extrusion block 243 gradually contacts the driving block 244 and squeezes the driving block 244 to move. Since the driving block 244 is formed on the moving part 22 and the moving part 22 can only move in the up and down directions, the driving block 244 and the moving part 22 move upward synchronously and drive the ventilator 23 to be ejected.

[0041] In another embodiment provided by the present invention, it should be noted that, in this embodiment, a square notch 26 is provided on the lower side plate of the tray 2, that is, in this embodiment, there is only a first hole but no second hole, and the lower end of the ventilator 23 is not restricted. Moreover, in this embodiment, the sliding rod 242 and the inner side wall of the mounting groove 25 have a certain spacing in the horizontal direction, and the width of the spacing is greater than the width of the sliding rod 242. The spacing is to facilitate the sliding rod 242 to move in the horizontal direction away from the moving member 22. The spacing is defined as a staggered spacing, and the spacing between the moving member 22 and the inner side wall of the mounting groove 25 is also the same. The sliding rod 242 has a certain spacing, which is not less than the staggered spacing. When the sliding rod 242 slides in the horizontal direction in the direction away from the moving member 22, the sliding rod 242 slides to the staggered spacing. At this time, the sliding rod 242 and the moving member 22 no longer have a part in contact with each other, that is, at this time, the sliding rod 242 no longer limits the moving member 22. In this way, the moving member 22 and the sliding rod 242 can be completely staggered; the inner wall of the installation groove 25 away from the sealing door 11 is provided with a sliding groove 251, and the extension direction of the sliding groove 251 is parallel to the upper end of the moving member 22. The elastic limiting rod 241 The slide 251 is slidably installed in the slide 251; two card slots 252 are provided in the slide 251, and the connection line between the two card slots 252 is parallel to the extension direction of the slide 251. A card block (not shown in the figure) is formed at one end of the elastic limiting rod 241 located in the slide 251, and the card block and the card slot 252 are correspondingly arranged. In the initial state, the card block is engaged in the card slot 252 on the side away from the side wall of the tray 2, which is defined as the first engaging position. In this position, the trapezoidal extrusion block 243 and the driving block 244 are correspondingly arranged, and the driving block 244 is in the movement direction of the trapezoidal extrusion block 243; when When the card block is engaged in another card slot 252, this is defined as the second engaging position. In this position, the sliding rod 242 is located on the outside of the moving member 22 in the horizontal direction, and the trapezoidal extrusion block 243 is staggered with the driving block 244 (the sliding rod 242 and the moving member 22 are also staggered). Under the gravity of the moving member 22, the moving member 22 moves downward and causes the ventilator 23 to move downward and disengage from the through hole 21 (at this time, the height of the ventilator 23 is lower than the height of the upper end of the through hole 21, and this state is defined as a recessed state). Then, the moving member 22 is pulled outward to quickly separate from the supporting tray 2.When it is necessary to separate the moving member 22 from the tray 2, the sliding rod 242 is driven to move in the horizontal direction and the elastic limiting rod 241 is driven to move synchronously. At this time, the card block pops out from the card slot 252 at the first card position and slides along the slide slot 251. When the card block slides to the second card position, the card block is carded in the corresponding card slot 252. At this time, the trapezoidal extrusion block 243 and the driving block 244 are staggered, and the moving member 22 and the sliding rod 242 are also staggered. Under the action of the moving member 22's own gravity, the moving member 22 moves downward, and the ventilator 23 is separated from the through hole 21. The ventilator 23 is no longer restricted. At this time, the moving member 22 can be pulled outward to quickly separate the moving member 22 from the tray 2, which is convenient for replacing parts or cleaning separately. ;

[0042] It can be seen from the above working process that the air cylinder 23 has three working states, namely, a flush state, an ejected state and a recessed state; in the flush state, the upper end of the air cylinder 23 and the upper end of the through hole 21 are in the same horizontal plane, which can prevent dust from entering and maintain a complete plane; in the ejected state, the upper end height of the air cylinder 23 is greater than the upper end height of the through hole 21, which can prevent food from blocking the through hole 21; in the recessed state, the upper end height of the air cylinder 23 is less than the upper end height of the through hole 21, which facilitates the rapid separation of the moving part 22 and the supporting tray 2.

[0043] Furthermore, the number of the bearing trays 2 is at least three. When it is necessary to drain water or clean the upper surface of the bearing tray 2, it is usually necessary to remove the bearing trays 2 one by one, process them and then put them back, which is time-consuming and laborious. Therefore, this embodiment provides a further solution to solve the above technical problems. In this embodiment, it should be particularly noted that, different from the foregoing embodiments, two limiting brackets 12 in the same horizontal plane can slide on the horizontal plane and the sliding directions are similar or opposite. The radial cross-section of a single limiting bracket 12 is in a U shape. A plurality of limiting brackets 12 on the same side in the vertical direction are connected together by a connecting member 13. It further includes an electric push rod installed on the furnace body 1. The movable section of the electric push rod is fixedly connected to the connecting member 13 to control the synchronous movement of a plurality of limiting brackets 12 on the same side. In addition, in this embodiment, the bearing tray 2 is of a split structure. A separation opening is formed in the middle of the bearing tray 2 to divide the bearing tray 2 into a first tray 28 and a second tray 29. The first tray 28 and the second tray 29 are rotatably connected together by a rotating shaft 14. The moving member 22 is also divided into a first moving member 221 and a second moving member 222. It should be noted that the first moving member 221 and the second moving member 222 are not connected to the rotating shaft 14 (the first moving member 221 and the second moving member 222 can be regarded as a reduced version of the moving member 22). The first moving member 221 and the second moving member 222 are also in a plate shape. The first moving member 221 and the second moving member 222 are not directly connected, but they are on the same horizontal plane. One end of the rotating shaft 14 away from the sealing door 11 is slidably inserted into a chute (not shown in the figure) on the inner wall of the fumigation chamber. When the bearing tray 2 moves outwards, the rotating shaft 14 can be separated from the inner wall of the fumigation chamber. In this way, when the two ends of the bearing tray 2 are respectively slidably installed in two limiting brackets 12 in the same horizontal plane, the bearing tray 2 can maintain a horizontal state. After the fumigation is completed, the two connecting members 13 are driven to move in opposite directions, so that the limiting brackets 12 are gradually separated from the bearing tray 2. When the limiting brackets 12 are completely separated from the bearing tray 2, under the action of the self-gravity of the bearing tray 2, both ends of the first tray 28 and the second tray 29 away from the rotating shaft 14 rotate downwards, and the whole bearing tray 2 is in an inverted V shape. In this way, the liquid on the bearing tray 2 automatically flows down under the action of gravity and drives the impurities to flow down as well. In this way, rapid synchronous draining of a plurality of bearing trays 2 and a certain degree of impurity cleaning are realized. Moreover, when the fumigation machine does not work for a long time, the bearing tray 2 can also be kept in an inverted V shape to尽量 avoid dust staying on the upper surface of the bearing tray 2.

[0044] Furthermore, the vents 23 on the first plate 28 and the second plate 29 are arranged in a one-to-one correspondence, and a first compression spring is sleeved on one of the vents 23 on the first plate 28, and the first compression spring is connected between the inner wall of the mounting groove 25 and the first movable member 221; a second compression spring is sleeved on one of the vents 23 on the second plate 29, and the second compression spring is connected between the mounting groove 25 and the second movable member 222; the first compression spring and the second compression spring have the same function, and are both used to maintain the position of the movable member 22 in the mounting groove 25, and are therefore collectively referred to as compression springs 27; in addition, one end of the vent 23 located below the supporting tray 2 is an inclined surface, and the corresponding inclined surfaces on the vent 23 can be butt-jointed together, and the length of the vent 23 is also different, and the closer the vent 23 is to the rotating shaft 14, the shorter the length, that is, the closer the vent 23 is to the rotating shaft 14, the more it extends downward. The smaller the distance between them, the easier it is to connect multiple corresponding vents 23 together at the same time; moreover, the through opening 231 is opened in the front and rear directions of the vents 23, so as to prevent liquid from flowing into the vents 23 when the vents 23 are pushed out of each other; when the limit bracket 12 is completely separated from the support tray 2, under the action of the support tray 2's own gravity, the ends of the first plate 28 and the second plate 29 away from the rotating shaft 14 both rotate downward. Since the vents 23 are extended out of the support tray 2 at this time, the corresponding vents 23 collide with each other synchronously, and the impact of the vents 23 is buffered by the compression spring 27, so that the support tray 2 also contacts elastically, thus avoiding damage to the support tray 2. After the first impact, the impact amplitude of the first plate 28 and the second plate 29 gradually decreases, which is equivalent to the first plate 28 and the second plate 29 both vibrating, so that it is easier to separate the liquid and impurities on the first plate 28 and the second plate 29.

[0045] Furthermore, an elastic extrusion portion 232 is provided in the middle of the vent cylinder 23. The elastic extrusion portion 232 will be squeezed and deformed when subjected to a certain pressure. The elastic extrusion portion 232 is preferably made of rubber. In this way, when the corresponding vent cylinders 23 collide with each other, the inclined surfaces at the lower ends of the vent cylinders 23 are butted together and squeezed against each other to seal. At this time, the elastic extrusion portion 232 is compressed and contracted, and the internal space of the vent cylinder 23 is reduced. In this way, when the vent cylinders 23 are squeezed against each other and pushed out, the gas in the vent cylinder 23 is also quickly squeezed out from the port 231. In this way, the gas impact on the inner wall of the vent cylinder 23 is achieved, and the residue on the vent cylinder 23 can be loosened and flushed out.
