Description

Technical Field

[0001] This invention relates to a commercial modular quick-change smoking and roasting equipment and its control method, belonging to the technical field of the food processing industry. Background Technology

[0002] Traditional commercial smoking and grilling equipment typically employs an integrated structure, with fuel supply, ignition, air supply, and control systems all integrated within the equipment. While this structure achieves a degree of functional centralization, it presents the following technical challenges in practical use: Difficult to maintain and high risk of downtime: Once the core control or feeding system fails, the entire machine needs to be shut down for repair, and the repair process is complex and time-consuming, which seriously affects commercial operations.

[0003] High coupling between functional modules: There is a lack of independence between the systems. Upgrading or replacing a functional module often requires modification of the entire machine, resulting in poor adaptability.

[0004] Unreliable flue gas sealing: Traditional connection methods are difficult to achieve long-term effective sealing under high-temperature flue gas conditions, which can easily lead to flue gas leakage, affecting cooking results and safety.

[0005] Low control precision and poor fuel adaptability: Existing equipment is mostly mechanically controlled, making it difficult to flexibly adjust the combustion state according to the type of fuel (such as wood pellets and charcoal), and thus unable to achieve precise temperature control and multi-mode cooking.

[0006] Therefore, there is an urgent need for a commercial grilling and roasting equipment that is modular, quick-changeable, intelligently controlled, and reliably sealed, in order to improve the equipment's reliability, maintainability, and cooking performance. Summary of the Invention

[0038] Example 1: As Figures 1 to 5 As shown in the figure, this embodiment provides a commercial modular quick-change smoking and grilling equipment, which mainly includes a smoking and grilling machine body 1 and an independently set integrated intelligent control cabin 2. The two are quickly connected and separated through a quick-change interface system.

[0039] 1. Main structure of the smoker / grill The main body 1 of the smoker has a cooking cavity for holding food. A hot air diversion hood 11 is installed at the bottom of the cooking cavity and above the smoke inlet to guide the vertically rising high-temperature smoke to the surrounding area, so that the temperature field inside the cavity is evenly distributed and the smoking effect is improved.

[0040] The main body is also equipped with a sealed feeding pipe 12 that is independent of the main furnace door. Its outer end is equipped with an openable and closable sealed door 121, and its inner end leads to the combustion zone or cooking chamber of the control compartment. It is used to replenish fuel without opening the main furnace door, thereby reducing heat loss and flue gas leakage.

[0041] 2. Integrated intelligent control cabin structure The integrated intelligent control cabin 2 is the core functional module of the equipment, which integrates a control unit, a fuel supply device, an ignition device, and an air supply device.

[0042] The fuel supply device is a wood pellet feeding module, including a wood pellet storage bin and a feeding motor 21 controlled by a microcomputer. The control unit adjusts the rotation speed, feeding time and interval of the feeding motor 21 to achieve precise fuel delivery, and the pellets are output through the pellet feeding pipe 212.

[0043] Smoke and Combustion System: A diversion-type smoke generation platform 22 is located below the discharge port of the feeding motor 21. At least one diversion column 221 is installed on its surface to extend the heating path of the wood particles and enhance the smoke generation effect. An air pressure cover 23 is installed above the platform to spray air downwards to suppress flame upward movement and isolate the smoke generation zone from the combustion zone. A guide plate 42 and a heating rod 41 are located below the platform for ignition. The combustion zone has a high-efficiency combustion chamber 24, with a continuously variable DC oxygen supply fan 25 at its bottom. The control unit adjusts the fan speed to control the oxygen supply, thereby precisely controlling the combustion intensity and furnace temperature. A pressure boosting air vent 231 is located on the side wall of the combustion chamber, and a manual flame control damper 43 is located at the air inlet for manual auxiliary airflow adjustment.

[0044] The guide plate 42 is usually provided with several holes, and also serves to block the flame.

[0045] Ash removal structure: The bottom of the control compartment is equipped with a sealed ash collection bin 46, which contains a drawer-type pull-out sealed ash collection box 44. The ash collection box is equipped with a sealed ash collection box safety door 45, which facilitates ash removal and prevents flue gas leakage.

[0046] 3. Quick-switch interface system The quick-change interface system includes a mechanical positioning and locking mechanism, a flue gas sealing mechanism, and an electrical quick-connect mechanism, which are used to achieve a quick and reliable connection between the control compartment and the main body.

[0047] Mechanical positioning and locking mechanism: including guide rails located at the bottom of the main body 1 of the smoker or at the top of the integrated intelligent control compartment 2, and at least one pair of lever-type quick-release buckles 31. The operator can manually operate the buckles without tools to achieve a secure lock and quick release.

[0048] Flue gas sealing mechanism: A sealing groove is provided around the flue gas outlet or inlet, with a high-temperature resistant flexible sealing strip 32 embedded inside, which can withstand a long-term temperature of not less than 700°C. When the quick-release buckle 31 is locked, the clamping force causes the sealing strip 32 to deform, sealing the gap at the mating interface and ensuring no leakage of high-temperature flue gas.

[0049] Electrical quick-connect mechanism: including aviation socket 33 on the main body and aviation plug 34 on the control cabin. Both have anti-misplugging structure and can realize the quick connection of power supply and sensor signal simultaneously to ensure stable and reliable signal transmission.

[0050] 4. Control methods The control unit has pre-stored control algorithms for various fuels and can automatically execute the following logic based on the cooking mode selected by the user: Low-temperature smoke mode: The feeding motor 21 intermittently feeds a small amount of material, and the oxygen supplementing fan 25 runs at low speed, so that the fuel is in a smoldering state and produces smoke. High-temperature smoking mode: Increase the amount and frequency of material supply, increase the fan speed, and promote complete combustion of fuel to increase the furnace temperature; Smokeless high-temperature baking mode: The fan operates at high power, providing excess oxygen to ensure complete combustion of fuel, eliminating visible smoke and achieving high temperatures.

[0051] This embodiment can use a metal door or a partially transparent glass door. Figure 5 This is a schematic diagram of the structure of the transparent glass door used in this invention.
