Description

Technical Field

[0001] The utility model belongs to the technical field of food mechanical processing, and in particular relates to a device capable of generating smoke at a constant temperature and used at the rear of a smoking furnace. Background Art

[0002] In the food processing industry, smokers are a multifunctional equipment that integrates steaming, drying and smoking, and are widely used in the processing of sausages, bacon, seafood and other meat products. As consumers' requirements for food quality continue to increase, the technology of smokers is also constantly innovating to meet the market's higher requirements for food flavor, color and safety.

[0003] Traditional smoke ovens usually place wood or plant materials directly in the oven to generate smoke and aroma through heating, thus achieving food smoking. However, this method has many shortcomings: first, the smoke is generated unevenly, resulting in inconsistent food smoking effects; second, the temperature is difficult to accurately control, affecting food safety and product quality during the smoking process; third, smoke emissions are not environmentally friendly and are likely to cause environmental pollution.

[0004] In recent years, with the advancement of technology, some new types of smoke generators have emerged, such as electric heating smoke generators and gas combustion smoke generators, which have solved the shortcomings of traditional smoke generators to a certain extent. However, most of these devices are installed on the top or side of the smoke furnace, and there are problems such as uneven smoke distribution and large temperature fluctuations, which make it difficult to meet the needs of high-precision and high-efficiency smoking.

[0005] For example, a Chinese patent with application number CN2021232958522 discloses a multifunctional fumigation furnace, including a furnace body, a smoke generating device is provided on one side of the furnace body, a smoke purification device is provided on the other side, a plurality of placement plates are provided in the furnace body, a power driving device for driving the placement plates in and out of the furnace body is provided on the furnace body, and a steam generating device for conveying steam into the furnace body is also provided on the furnace body. The utility model is safe to use, convenient to operate, has good fumigation effect, high fumigation efficiency, energy saving and environmental protection, and is especially a multifunctional fumigation furnace that can effectively prevent operators from being scalded by gas in the fumigation furnace.

[0006] However, after the smoke generated by the smoke generating device in the application enters the furnace body, it diffuses unevenly, affecting the fumigation effect. At the same time, various detectors and temperature sensors are used to detect the smoke concentration, humidity and temperature in the furnace body, and the detectors and sensors are installed in the furnace body at the same time. After long-term use, the smoke used for fumigation damages the temperature sensor, affecting the detection effect, failing to achieve the corresponding application effect, and affecting the fumigation quality and efficiency.

[0008] In order to solve the above technical problems, the utility model provides the following technical solutions:

DETAILED DESCRIPTION

[0022] like Figure 1-2 As shown: a device capable of emitting smoke at a constant temperature at the rear of a smoking furnace device, comprising a smoking furnace 1 and a smoking device 4, the smoking furnace 1 and the smoking device 4 being connected via a connecting pipe 3, a smoke dispersing pipe 12 being installed on the inner bottom surface of the smoking furnace 1, both sides of the smoke dispersing pipe 12 being provided with smoke outlet holes 13 in a linear array, one end of the connecting pipe 3 penetrating the outer wall of the smoking furnace 1 and being connected with the smoke dispersing pipe 12, a smoke detector 14 being fixedly installed at the upper position of the inner wall of the smoking furnace 1, an electric heating plate 47 being arranged on the inner bottom surface of the smoking device 4, and a wind control device being arranged on the outer upper end surface of the smoking device 4.

[0023] In this embodiment, the smoking oven 1 is directly placed on the ground for use.

[0024] A furnace door 11 is hingedly connected to one side of the smoke oven 1 , and a first door lock (not shown in the figure) is installed on the furnace door 11 . The furnace door 11 can be locked to the smoke oven 1 through the first door lock.

[0025] A first sealing strip is fixedly installed on the edge of one side of the furnace door 11 close to the smoking furnace 1, which is not marked in the figure. When the furnace door 11 is closed, the first sealing strip plays a sealing role to prevent smoke from overflowing and causing pollution to the surrounding environment.

[0026] A food rack is movably placed inside the smoking furnace 1 at a position above the smoke dispersing pipe 12 (not shown in the figure). The food rack is made by welding food-grade square tubes of different lengths. The food rack is divided into multiple layers from top to bottom by a diamond mesh for placing food that needs to be smoked. At the same time, a plurality of hooks are provided on the upper end of the food rack for hanging food that needs to be smoked.

[0027] In the prior art, the welding arrangement of the food rack can be arranged according to demand, and the arrangement is well known and will not be described in detail here.

[0028] A fan 15 is fixedly mounted on the top surface of the interior of the smoke oven 1 , and the function of the fan 15 is to exhaust the smoke inside the smoke oven 1 .

[0029] A smoke outlet pipe 16 is connected to a position outside the smoke oven 1 corresponding to the fan 15 , and smoke exhausted by the fan 15 enters the smoke outlet pipe 16 .

[0030] The other end of the smoke outlet pipe 16 is connected to a smoke purification device, which is not shown in the figure. With this design, the smoke after fumigation is treated by the smoke purification device and then discharged to the external environment, avoiding pollution to the external environment and meeting environmental protection requirements.

[0031] In the prior art, the flue gas purification treatment device usually adopts a treatment method of adsorbing harmful substances in the flue gas. The specific adsorption principle is well known and will not be described here.

[0032] A control box 2 is fixedly mounted on the outer wall of the smoking furnace 1 near the upper end.

[0033] The control box 2 is equipped with a control system for controlling an air control device and receiving signals from a smoke detector 14 .

[0034] The signal output end of the smoke detector 14 is electrically connected to the control system.

[0035] The smoke generating device 4 comprises a smoke generating box 41 connected to the connecting pipe 3 . The smoke generating box 41 is located at a side of the smoking furnace 1 away from the furnace door 11 .

[0036] A door 42 is hingedly connected to one side of the smoke box 41 away from the connecting pipe 3 , and a second door lock for locking the door 42 is installed on the door 42 , which is not marked in the figure.

[0037] A second sealing strip is fixedly installed at the edge of one end surface of the door 42 close to the smoke box 41, which is not marked in the figure. When the door 42 is closed, the second sealing strip plays a sealing role to prevent smoke from leaking out.

[0038] The control end of the electric heating plate 47 is electrically connected to the control system through an electric wire.

[0039] In this embodiment, the working principle of the electric heating plate 47 is mainly based on the resistance heating effect, that is, converting electrical energy into thermal energy to heat an object, and a control circuit is used to detect and adjust the temperature of the electric heating plate 47 to achieve temperature control.

[0040] A material discharging box 48 is movably placed on the upper surface of the electric heating plate 47 , and the material discharging box 48 is made of heat-conducting stainless steel.

[0041] The electric heating plate 47 is controlled and driven by the control system to ensure that the heating temperature of the electric heating plate 47 is constant, thereby achieving constant temperature smoke generation.

[0042] The material required for smoking is placed in the material discharge box 48, and then the material discharge box 48 is heated by the electric heating plate 47, and then the material for smoking in the material discharge box 48 is heated to generate smoke.

[0043] The wind control device includes an air inlet pipe 43 connected to the upper end of the smoke box 41 . Cylinder mounting frames 45 are provided on both sides of the air inlet pipe 43 . The cylinder mounting frames 45 are fixedly mounted on the smoke box 41 .

[0044] A cylinder 46 is vertically arranged on the upper end surface of the cylinder mounting frame 45 , and a cover 44 is fixedly mounted on the power output end of the cylinder 46 after passing through the cylinder mounting frame 45 .

[0045] The outer diameter of the cover 44 matches that of the air inlet pipe 43 , and the cover 44 is in movable contact with the air inlet pipe 43 .

[0046] With such a design, the cylinder 46 drives the sealing cover 44 to move up and down. When the cylinder 46 drives the sealing cover 44 to move downward until the sealing cover 44 touches the end of the air inlet pipe 43, the air inlet pipe 43 is blocked to prevent air from entering the smoke box 41, thereby controlling and reducing the amount of smoke. When the cylinder 46 drives the sealing cover 44 to move upward until the sealing cover 44 separates from the air inlet pipe 43, more air enters the smoke box 41, thereby increasing the amount of smoke.

[0047] At the same time, by controlling the distance between the cover 44 and the air inlet pipe 43, the total amount of air entering the smoke box 41 can be adjusted, thereby achieving the adjustment of the smoke amount.

[0048] By adopting this method for adjustment, the application of temperature sensors is reduced, thereby reducing the maintenance rate of the smoke generating device 4 and the fumigation furnace 1.

[0049] When in use, the products to be smoked are placed on the food placement rack, the oven door 11 is closed, the smoking materials are placed on the material discharge box 48, the oven door 42 is closed, and the control system controls the drive cylinder 46 to start, and the power output end of the cylinder 46 drives the cover 44 to move to a position away from the air inlet pipe 43 until the distance between the cover 44 and the air inlet pipe 43 is the maximum.

[0050] The control system controls the electric heating plate 47 to turn on, and the electric heating plate 47 is heated to a preset temperature, and then smokes the smoking material. The generated smoke enters the smoke pipe 12 through the connecting pipe 3, and then spreads upward from the bottom of the inside of the smoking furnace 1 through the smoke outlet 13 until it fills the inside of the smoking furnace 1, and smokes the product to be smoked.

[0051] When the smoke detector 14 detects that the smoke concentration in the smoke oven 1 reaches a preset value, the smoke detector 14 feeds back a signal to the control system, and the control system drives the cylinder 46 to drive the cover 44 to move downward, shortening the distance between the cover 44 and the air inlet pipe 43, thereby reducing the air entering the smoke box 41 and reducing the amount of smoke;

[0052] When the smoke detector 14 detects that the smoke concentration in the smoke oven 1 is low, the smoke detector 14 feeds back a signal to the control system, and the control system drives the cylinder 46 to move the cover 44 upward, increasing the distance between the cover 44 and the air inlet pipe 43, thereby increasing the air entering the smoke box 41 and increasing the amount of smoke.

[0053] During this period, the electric heating plate 47 is kept at a constant temperature to ensure that the temperature of the smoke is constant.

[0054] At the same time, the smoke spreads upward from the bottom of the interior of the smoke oven 1, ensuring that the smoke can fully fumigate the smoked product.

[0055] When fumigation is completed, the control system controls the electric heating plate 47 to close, and at the same time controls the cylinder 46 to drive the sealing cover 44 to contact the air inlet pipe 43, isolate the air, and then stop smoking. During this period, the fan 15 is always in the on state to prevent the smoke from overflowing from the air inlet pipe 43 while allowing the smoke to quickly spread to the inside of the fumigation furnace 1. After the fumigation is finally completed, the remaining smoke in the fumigation furnace 1 is discharged through the smoke pipe 16 and the smoke purification device.

[0056] For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and deformations made to the implementation methods are still within the protection scope of the present invention.
