Description

Technical Field

[0001] This utility model relates to the field of cured meat smoking technology, and in particular to a smoke-smoking box for cured meat products with a smoke exhaust structure. Background Technology

[0002] Cured meat is a raw meat product made from fresh meat, seasoned with various spices, and processed through marinating, baking, and smoking (or without smoking). Among these processes, smoked meat products are more widely produced and consumed in daily life. Smoking enhances flavor and improves the appearance and color of the meat through the Maillard reaction. The smoke forms a protective layer on the surface of the meat, ensuring it doesn't spoil for a long time and retains a rich flavor. Smoking is one method of making cured meat; smoked cured meat doesn't spoil easily and has a delicious, smoky aroma. When cooked and sliced, the lean meat is a glossy reddish-brown, while the fat is oily but not greasy, making it suitable for both formal occasions and side dishes.

[0003] Traditional smoking equipment for cured meat products generally suffers from the following defects:

[0004] Uneven smoke distribution: Static smoking results in uneven smoke distribution on the cured meat, affecting the consistency of flavor;

[0005] Grease contamination problem: dripping grease can easily come into contact with heat sources, producing a burnt smell or open flame, posing a safety hazard;

[0006] Inadequate smoke treatment: Direct emission of flue gas containing particulate matter and tar pollutes the environment and fails to meet environmental protection requirements. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a smoke extraction box for wax products.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A smoke-exhausting box for wax products includes a smoke-exhausting box, a transparent door hinged to the outer wall of the smoke-exhausting box, a slow motor fixed to the top of the smoke-exhausting box by bolts, and a hanging bracket located inside the smoke-exhausting box installed at the bottom of the output shaft of the slow motor, with hooks evenly spaced and arranged in a ring fixed to the bottom of the hanging bracket.

[0010] In the above scheme, a slow-speed motor drives the suspension frame to rotate, so that the cured meat rotates at a uniform speed on the ring hook, achieving smoked smoke without dead angles and improving the uniformity of flavor penetration.

[0011] An oil collection tray is attached to the inner wall of the smoking chamber;

[0012] The lower part of the smoking chamber has baffles fixed on both sides of the inner wall at equal intervals, and the baffles are sequentially connected to a filter plate, a grid plate one and a grid plate two. The filter plate, grid plate one and grid plate two sequentially divide the lower part of the smoking chamber into a smoke generating chamber, a heating chamber and an ash storage chamber.

[0013] In the above scheme, layered combustion control, a three-layer isolation structure filter plate, grid plate one, and grid plate two with overlapping baffles, and a blower to precisely control oxygen, maintain stable combustion of fruitwood charcoal, and smoke ingredients such as sugar and tea volatilize their aroma when heated to avoid direct carbonization, resulting in pure smoke rising and reducing particulate matter adhering to the surface of cured meat.

[0020] Preferably, the second grid plate is provided with fruitwood charcoal, and the first grid plate contains smoking seasonings.

[0021] Preferably, the filter box is provided with a smoke exhaust pipe at the top, and a sealing plate is fixed on one side of the outer wall of the filter box. The inner wall of the filter box has slots that are evenly distributed, and a first filter screen, a second filter screen and a third filter screen are inserted into the slots in sequence, with the mesh size of the first filter screen, the second filter screen and the third filter screen decreasing in sequence.

[0022] In the above scheme, the multi-stage filter box adsorbs tar and particulate matter in the flue gas through three stages of decreasing pore size filters, and then discharges it through the exhaust pipe in compliance with standards, thereby reducing environmental pollution.

[0023] The beneficial effects of this utility model are as follows:

[0024] Even smoking: The slow-speed motor drives the hanging frame to rotate, so that the cured meat rotates at a uniform speed on the ring hook, achieving 360° smoking without dead angles and improving the evenness of flavor penetration.

[0025] Highly efficient oil collection and pollution prevention: The inclined oil receiving tray with a 5°–10° tilt angle, combined with the drain pipe, automatically guides and collects dripping oil, preventing the oil from coming into contact with heat sources and causing combustion, thus ensuring food safety.

[0026] Layered combustion control, with a three-layer isolation structure of filter plate, grid plate one, and grid plate two connected by baffles, and a blower for precise oxygen control, maintains stable combustion of fruitwood charcoal. Smoking materials such as sugar and tea release their aroma when heated, avoiding direct carbonization. Pure smoke rises, reducing particulate matter adhering to the surface of cured meat.

[0027] Environmentally friendly smoke extraction: The multi-stage filtration box adsorbs tar and particulate matter in the smoke through three stages of decreasing pore size filters, and the smoke is discharged in compliance with standards through the exhaust pipe, reducing environmental pollution.
