Description

Technical Field

[0001] This utility model belongs to the technical field of smokehouse equipment, and in particular, a smokehouse with controllable temperature. Background Technology

[0002] In the food processing industry, smoking boxes (also known as smokehouses) are common equipment, widely used in the flavoring and processing of various foods. Their main function is to impart a unique smoky flavor to food, while also performing important functions such as drying, steaming, and sterilization. They play a crucial role in improving food quality, extending shelf life, and enriching the taste of food.

[0003] Traditional smoking ovens typically consist of separate smoking and heating units. However, this design has significant drawbacks in actual operation. The smoking unit generates heat during operation, and this heat is transferred into the interior of the smoking oven. Because this heat transfer process is difficult to precisely control, the temperature inside the smoking oven fluctuates significantly, making precise temperature control impossible. In food processing, precise temperature control is one of the core elements for ensuring processing quality and results. Excessive temperature can lead to over-burning of the food surface, insufficient internal cooking, and even damage to the food's nutrients and flavor compounds. Utility Model Content

[0004] In view of this, the present invention provides a temperature-controllable smokehouse with precise temperature control to meet industrial needs.

[0005] A temperature-controllable smokehouse includes a housing, a chimney mounted on the housing, a smoke chamber within the housing, a smoking section within the housing and spaced apart on one side of the smoke chamber, a connecting channel connecting the smoking section and the smoke chamber, and a heat circulation mechanism located on one side of the housing and communicating with the smoke chamber. The smoke chamber includes a main body, a protective shell on the outer wall of the main body, and a heat insulation layer between the main body and the protective shell. The smoking section includes a feeding mechanism within the housing for transporting wood, a smoking mechanism connected to one side of the feeding mechanism, and a wood transport pipe between the feeding mechanism and the smoking mechanism. One end of the connecting channel connects to the smoke chamber, and the other end connects to the smoking mechanism, allowing smoke generated by the smoking mechanism to be transported into the smoke chamber.

[0006] Furthermore, the smoking chamber also includes a control device disposed on the smoking chamber, the control device being connected to the smoking section and the heat circulation mechanism.

[0007] Furthermore, the smoking section also includes a heat insulation plate disposed between the feeding mechanism and the smoking mechanism.

[0008] Furthermore, the outer contour of the connecting channel is at a 90-degree angle.

[0009] Furthermore, the connection channel includes a connection channel body, a connection channel protective layer disposed on the outside of the connection channel body, and a connection channel heat insulation layer disposed between the connection channel body and the connection channel protective layer.

[0010] Furthermore, the heat circulation mechanism includes a hot air baffle fixedly connected to the smokehouse body, a heating cavity disposed on one side of the smokehouse body and the hot air baffle, a heat circulation fan disposed in the heating cavity, a heating device disposed around the outside of the heat circulation fan, and a heat circulation air inlet and a heat circulation air outlet connecting the smokehouse body and the heating cavity.

[0011] Furthermore, the heat circulation mechanism includes a hot air baffle fixedly connected to the smokehouse body, a heating cavity disposed on one side of the smokehouse body and the hot air baffle, a heat circulation fan disposed in the heating cavity, a heating device disposed around the outside of the heat circulation fan, and a heat circulation air inlet and a heat circulation air outlet connecting the smokehouse body and the heating cavity.

[0012] Furthermore, the filter assembly includes a filter frame and a plurality of filter rods arranged at intervals. The plurality of filter rods are arranged in two layers, with the filter rods in one layer being staggered with the filter rods in the other layer. The ash storage frame is spaced apart from the free end of the drawer.

[0013] Furthermore, the chimney is connected to the smoking chamber.

[0014] Furthermore, the feeding pipe is inclined, with the end of the feeding pipe facing the feeding mechanism being higher than the end of the feeding pipe facing the smoking mechanism.

[0015] Compared with existing technologies, the temperature-controllable smokehouse provided by this utility model features a smoke chamber and a smoke section spaced apart, with smoke from the smoke section transferred to the smoke chamber via a connecting channel. This spaced-apart arrangement reduces heat transfer from the smoke section to the smoke chamber. Furthermore, a heat insulation layer is provided between the smoke chamber body and the protective shell, enhancing the insulation effect of the smoke chamber body and preventing heat transfer from the smoke section to the smoke chamber. Thus, during the smoking process, the smoke chamber is heated only through the heat circulation mechanism, achieving temperature control within the smoke chamber. Therefore, this temperature-controllable smokehouse achieves precise control of the heat transfer process, avoiding temperature fluctuations within the smoke chamber and realizing accurate temperature control.

[0023] like Figures 1 to 6The diagram shown is a structural schematic of the temperature-controllable smokehouse provided by this utility model. The temperature-controllable smokehouse includes a housing 1, a chimney 2 mounted on the housing 1, a smoke chamber 10 disposed within the housing 1, a smoke section 20 disposed within the housing 1 and spaced apart from one side of the smoke chamber 10, a connecting channel 30 connecting the smoke section 20 and the smoke chamber 10, a heat circulation mechanism 40 disposed on one side of the housing 1 and communicating with the smoke chamber 10, a control device 50 mounted on the smoke chamber 10, and an ash removal device 60 mounted on the housing 1. The temperature-controllable smokehouse also includes other functional modules, such as assembly components, electrical connection components, etc., which should be known to those skilled in the art and will not be described in detail here.

[0024] The box 1 is used to integrate the smoking box 10, the smoking section 20, the connecting channel 30, and the heat circulation mechanism 40 into a whole. A movable door panel is provided on one side of the box 1 so that the user can place the smoked food and the combustible material in the smoking box 10. The box 1 is a prior art and will not be described in detail here.

[0025] The chimney 2 is connected to the smoking chamber 10 to discharge the smoke from the smoking chamber 10. The connection structure between the chimney 2, which passes through the chamber 1, and the smoking chamber 10 is a prior art and will not be described in detail here.

[0026] The smoking chamber 10 includes a smoking chamber body 11, a protective shell 12 disposed on the outer side wall of the smoking chamber body 11, and a smoking chamber heat insulation layer 13 disposed between the smoking chamber body 11 and the protective shell 12.

[0027] The smoking chamber body 11 is a box for placing food to be smoked. Multiple grilling racks are spaced apart inside the smoking chamber body 1. The smoke generator 2 is a device that generates smoke, using the smoke produced by the incomplete combustion of sawdust. The smoke generator 2 is mounted on the smoking chamber body 1, and the smoke generated by the smoke generator 2 smokes the food on each grilling rack. The chimney guides the smoke out of the smoking chamber body 1. The smoking chamber body 1, the smoke generator 2, and the chimney 3 are all existing technologies and will not be described in detail here. The outer contour of the protective shell 12 is consistent with the outer contour shape of the smoking chamber body 11. The protective shell 12 is spaced apart from the smoking chamber body 11 to limit the smoking chamber insulation layer 13 to the outside of the smoking chamber body 11, and the protective shell 12 protects the smoking chamber body 11 and the smoking chamber insulation layer 13.

[0028] The smoking chamber insulation layer 13 is made of heat-insulating material and is disposed between the protective shell 12 and the smoking chamber body 11 to improve the heat preservation effect inside the smoking chamber body 11 and prevent the smoking section 20 from interfering with the temperature inside the smoking chamber body 11. The smoking chamber insulation layer 13 is a prior art and will not be described in detail here.

[0029] The smoking section 20 includes a feeding mechanism 21 disposed in the box 1, a smoking mechanism 22 connected to one side of the feeding mechanism 21, a feeding pipe 23 for wood transfer disposed between the feeding mechanism 21 and the smoking mechanism 22, and a heat insulation plate 24 disposed between the feeding mechanism 21 and the smoking mechanism 22.

[0030] The feeding mechanism 21 includes a storage bin 211 disposed within the housing 1 for holding wood, and a conveying device 212 disposed on one side of the storage bin 211. The conveying device 212 is connected to the storage bin 211. The storage bin 211 conveys the wood to the conveying device 212, which then conveys the wood into the feeding pipe 23. The feeding pipe 23 guides the wood into the smoking mechanism 22. In this embodiment, the conveying device 212 consists of a motor and a lead screw. The wood in the storage bin 211 falls onto one side of the lead screw. When the motor drives the lead screw to rotate, the wood is gradually conveyed into the feeding pipe 23 under the guidance of the lead screw.

[0031] The fumigation mechanism 22 includes an installation pipe 221 disposed on one side of the feeding mechanism 21, a combustion chamber 222 disposed in the installation pipe 221, a fumigation generator 223 disposed on the combustion chamber 222, a fan 224 disposed in the installation pipe 221, a feed inlet 225 disposed on the installation pipe 221 and communicating with the combustion chamber 222, a smoke outlet 226 disposed on the installation pipe 221, and an ash outlet 227 disposed on one side of the installation pipe 221.

[0032] The mounting pipe 221 is used to integrate the fan 224, the smoke generator 223, and the combustion chamber 222 into a whole. The mounting pipe 221 is a prior art and will not be described in detail here.

[0033] The combustion chamber 222 is used to hold the wood, and one end of the smoke generator 223 is housed within the combustion chamber 222. The smoke generator 223 is used to ignite the wood in the combustion chamber 222.

[0034] The fan 224 is used to blow air toward the combustion chamber 222 to blow the smoke from burning wood into the smoke outlet 226. The ventilation structure between the fan 224 and the combustion chamber 222 is a prior art and will not be described in detail here.

[0035] The feed inlet 225 is connected to one end of the feeding pipe 23, so that the feeding mechanism 21 can transfer wood to the feed inlet 225 through the feeding pipe 23.

[0036] The smoke outlet 226 is located at the top of the combustion chamber 222, and the ash outlet 227 is located at the bottom of the combustion chamber 222. Both the smoke outlet 226 and the ash outlet 227 are existing technologies and will not be described in detail here.

[0037] The feeding pipe 23 is inclined, and the end of the feeding pipe 23 facing the feeding mechanism 21 is higher than the end of the feeding pipe 23 facing the smoking mechanism 221, thereby preventing the flame in the smoking mechanism 221 from burning into the feeding mechanism 21.

[0038] The heat insulation plate 24 separates the feeding mechanism 21 from the smoking mechanism 22 to prevent the heat generated by the smoking mechanism 22 from being transferred to the feeding mechanism 21. The heat insulation plate 24 is made of heat insulation material and has a clearance structure so that the feeding pipe 23 connects the feeding mechanism 21 and the smoking mechanism 22. The heat insulation plate 24 is a prior art and will not be described in detail here.

[0039] The connecting channel 30 includes a connecting channel body 31, a connecting channel protective layer 32 disposed on the outside of the connecting channel body 31, and a connecting channel heat insulation layer 33 disposed between the connecting channel body 31 and the connecting channel protective layer 32. One end of the connecting channel 30 is connected to the smoking chamber 10, and the other end of the connecting channel 30 is connected to the smoke outlet 226 in the smoking mechanism 22. The connection structure between the connecting channel 30 and the smoking chamber 10, and the smoke outlet 226 in the smoking mechanism 22, is a prior art, such as welding or riveting. The connecting channel heat insulation layer 33 prevents heat from the connecting channel 30 from being transferred to the smoking chamber 10, and the outer contour of the connecting channel is at a 90-degree angle, thereby preventing the flame in the smoking mechanism 22 from burning into the smoking chamber 10.

[0040] The heat circulation mechanism 40 includes a hot air baffle 41 fixedly connected to the smoking chamber body 11, a heating chamber 42 disposed on one side of the smoking chamber body 11 and the hot air baffle 41, a heat circulation fan 43 disposed in the heating chamber 42, a heating device 44 surrounding the outside of the heat circulation fan 43, and a heat circulation air inlet 45 and a heat circulation air outlet 46 connecting the smoking chamber body 1 and the heating chamber. The heat circulation unit 40 and the connecting channel 30 are respectively disposed on different side walls inside the smoking chamber body 1, so that during the transmission of smoke inside the smoking chamber body 11, the heat of the smoke is transferred to the side walls of the smoking chamber body 11, thereby conserving the heat of the smoking chamber body 11 and improving the efficiency of the smoking chamber body.

[0041] The hot air baffle 41 is fixedly connected to the smoke chamber body 11. The connection structure between the hot air baffle 41 and the smoke chamber body 11 is a prior art and will not be described in detail here.

[0042] The heating cavity 42 is used to house the hot air circulation fan 43 and the heating device 44. The heating cavity 42 and the smoking chamber body 1 form a semi-enclosed space. Airflow exchange between the heating cavity 42 and the smoking chamber body 1 is achieved only through the hot air circulation inlet 45 and the hot air circulation outlet 46. The connection structure between the heating cavity 42 and the smoking chamber body 1 is a prior art and will not be described in detail here.

[0043] The hot air circulation fan 43 corresponds to the hot air circulation inlet 45. That is, the hot air circulation fan 43 draws the air in the smoke chamber body 1 into the heating chamber 42. The hot air circulation fan 43 is a mechanical device that increases the gas pressure and discharges the gas by relying on the input mechanical energy. The hot air circulation fan 43 is a prior art and will not be described in detail here.

[0044] The heating device 44 is used to heat the air inside the heating chamber 42. The heating device 44 surrounds the outside of the heat circulation fan 43, so that when the heat circulation fan 43 draws in the air from the smoke chamber body 1, the heating device 44 also heats the air simultaneously. The heating device 44 is a prior art and will not be described in detail here.

[0045] The hot air circulation inlet 45 and the hot air circulation outlet 46 are used to exchange the air between the smoke chamber body 1 and the heating chamber 42. In this embodiment, the hot air circulation inlet 45 is located at the center of the hot air baffle 41, and the hot air circulation outlet 46 is located at the edge of the hot air baffle 41. Thus, during use, air enters at the center of the hot air baffle 41, and air can exit from the edges of the hot air baffle 41. The shape and structure of the hot air circulation inlet 45 and the hot air circulation outlet 46 are existing technologies and will not be described in detail here.

[0046] The control device 50 is connected to the smoking section 10 and the heat circulation mechanism 40. The control device 50 can control the operation of the smoking section 10 and the heat circulation mechanism 40. The control device 50 is a prior art, and the connection structure between the control device 50 and the smoking section 10 and the heat circulation mechanism 40 is also a prior art, which will not be described in detail here.

[0047] The ash removal device 60 includes a drawer 61 slidably connected to the housing 1, an ash storage frame 62 disposed within the drawer 61, and a filter assembly 63 disposed on the ash storage frame 62. The ash storage frame 62 supports the filter assembly 63, so that there is a gap between the filter assembly 63 and the drawer 61, which can accommodate the ash after the wood is burned.

[0048] The filter assembly 63 includes a filter frame 631 and a plurality of filter rods 632 arranged at intervals within the filter frame 631.

[0049] The multiple filter rods 632 are arranged in two layers, with the filter rods 632 in one layer being staggered with those in the other layer. That is, any two adjacent filter rods 632 in one layer are separated by a filter rod 632 from the other layer, so that the ash from burning wood can fall through the gaps between the filter rods 632 and prevent wood from falling off the filter assembly 63.

[0050] The ash storage frame 62 and the drawer 61 are spaced apart, so that there is a gap between the ash storage frame 62 and the drawer 61. When the ash removal device 60 is separated from the box 1, the gap between the ash storage frame 62 and the drawer 61 can slide on the ash outlet 227, and the ash in the combustion chamber 222 can fall into the gap between the ash storage frame 62 and the drawer 61, so that the ash in the combustion chamber 222 can fall completely into the ash removal device 60, thereby improving the ash storage effect of the ash removal device 60.

[0051] When the ash removal device 60 is installed on the housing 1, the filter assembly 63 corresponds to the ash outlet 227, and the filter assembly 63 supports the wood in the combustion chamber 222 so that the wood in the combustion chamber 222 can burn.

[0052] During use, the controllable smoking oven is controlled by the control device 50 to ignite the wood in the smoking section 20 and transfer the smoke from the smoking section 20 to the smoking chamber 10 through the connecting channel 30. The control device 50 also controls the heat circulation mechanism 40 to heat the smoking chamber 10. The smoking chamber 10 is heated only by the heat circulation mechanism 40, thus achieving precise temperature control of the smoking chamber 10.

[0053] Compared with the prior art, the temperature-controllable smokehouse provided by this utility model has a smoke chamber 10 and a smoke section 20 spaced apart, and the smoke in the smoke section 20 is transferred to the smoke chamber 10 through the connecting channel 30. The spaced-apart arrangement of the smoke chamber 10 and the smoke section 20 reduces heat transfer from the smoke section 20 to the smoke chamber 10. Furthermore, a smoke chamber insulation layer 13 is provided between the smoke chamber body 11 and the protective shell 12 in the smoke chamber 10. This insulation layer 13 enhances the insulation effect of the smoke chamber body 11, preventing heat transfer from the smoke section 20 to the smoke chamber 10. Therefore, during the smoking process, the smoke chamber 10 is heated only through the heat circulation mechanism 40, achieving temperature control within the smoke chamber 10. Thus, this temperature-controllable smokehouse achieves precise control of the heat transfer process, avoids temperature fluctuations within the smoke chamber, and achieves accurate temperature control.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
