Description

Technical Field

[0001] This utility model relates to the field of food drying technology, specifically a compact gas burner for food drying. Background Technology

[0002] Food drying is an important food processing technology aimed at removing moisture from food to inhibit the growth of microorganisms and bacteria, thereby extending its shelf life. This technology has a long history; in the past, people dried food by exposing it to sunlight and wind, providing an effective method for long-term food preservation before the widespread use of refrigeration or chemical preservatives. Today, food drying relies heavily on specialized drying equipment. Common drying methods include hot air circulation drying, such as in food drying rooms, which can quickly evaporate moisture from food, achieving high efficiency and energy saving without damaging the nutritional components. Different food drying equipment is suitable for different types of food. For example, rotary drum dryers are suitable for drying and roasting dried fruits such as peanuts and sunflower seeds, and can also handle high-moisture materials such as starch and soybean residue. Food dryers achieve drying by circulating hot air in a drying chamber. Through drying, fruits, vegetables, and meats can be better preserved, while also expanding the sales scope and time of these foods.

[0003] Most food drying equipment is large, takes up a lot of space, and is expensive, making it unaffordable for home use. Therefore, there is a need for a small-scale food drying device that can be used at home to meet the needs of some families and is also suitable for small-scale food drying work. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a compact gas burner for food drying, including a gas inlet pipe with an air inlet hole at the bottom. A solenoid valve is installed at the output end of the gas inlet pipe. A first adapter pipe is fixedly installed on the top of the solenoid valve. A double-pass pipe is fixedly installed at the output end of the first adapter pipe. A guide pipe is fixedly connected to the surface of the double-pass pipe. A second adapter pipe is fixedly connected to the output end of the double-pass pipe. A mixing chamber is fixedly connected to the output end of the second adapter pipe. A connecting pipe is fixedly connected to the bottom of the mixing chamber. A fan is fixedly connected to the input end of the connecting pipe. A fixed housing is installed on the surface of the fan. A limit sleeve is threaded to the left end of the mixing chamber. A protective plate is fixedly connected to the left end of the limit sleeve. A protective sleeve is fixedly connected to the left end of the protective plate. A gas nozzle is installed inside the protective sleeve. An air hole is opened on the surface of the protective sleeve. An ignition controller is installed at the input end of the guide pipe.

[0005] The above technical solution involves setting up an ignition controller. Gas enters the gas inlet pipe through the inlet hole. After the solenoid valve is opened, the gas flows through it into the transfer pipe, then through the gas inlet pipe into the double-pass pipe, and finally into the mixing chamber. Simultaneously, the fan is started, and its output drives air through the connecting pipe into the mixing chamber to mix with the gas. After mixing, the ignition controller is activated to ignite the mixed gas, and the heat is released through the gas nozzle, achieving the drying of the grain.

[0006] As a further improvement to the above solution, the solenoid valve and the transfer pipe are concentric.

[0007] The above technical solution, with the solenoid valve and the first transfer pipe concentrically positioned, ensures that the gas flow path within the pipeline is free of abrupt changes, reducing turbulence or pressure loss. This aligned design improves the stability of gas delivery, avoids seal failure or localized wear caused by eccentricity, and extends equipment lifespan.

[0008] As a further improvement to the above scheme, the first and second transfer pipes are symmetrically distributed at their centers.

[0009] Through the above technical solution, transfer pipe one and transfer pipe two are symmetrically distributed around the double-pass pipe, making the distribution of gas within the double-pass pipe more uniform. The symmetrical structure balances the airflow pressure on both sides of the pipe, preventing uneven mixing caused by flow deviation, while also simplifying the complexity of the pipe layout.

[0010] As a further improvement to the above solution, the output end of the guide tube is fixedly connected inside the double-pass tube, and the guide tube is located at the center of the front of the double-pass tube.

[0011] With the above technical solution, the guide tube is fixed at the center of the front side inside the dual-pass pipe, which can accurately introduce external air or auxiliary gas into the core area of ​​the dual-pass pipe to form a counter-mixing with the fuel gas. This central layout enhances the convergence effect of airflow, improves mixing efficiency, and reduces energy loss caused by offsetting.

[0012] As a further improvement to the above solution, the number of the limiting sleeves is set to several, and the several limiting sleeves are centrally symmetrically distributed on the right end surface of the protective plate.

[0013] Through the above technical solution, multiple limiting sleeves are distributed in a centrally symmetrical manner, enhancing the overall stability of the connection structure between the protective plate and the mixing box. The symmetrical design disperses external stress, avoiding deformation or loosening caused by single-point stress, while also facilitating disassembly and maintenance, and improving the operability of the equipment.

[0014] As a further improvement to the above scheme, the output end of the gas nozzle is located inside the mixing chamber.

[0015] With the above technical solution, the output end of the gas nozzle is located inside the mixing chamber, which can directly inject gas into the central area of ​​the mixing chamber and make full contact with the air introduced by the fan. This embedded design shortens the mixing path, reduces the risk of gas leakage during transportation, and ensures the efficiency and controllability of the mixing reaction.

[0016] As a further improvement to the above solution, the number of air holes is set to several, and the several air holes are distributed in a circle on the front of the protective sleeve.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention features an ignition controller. Gas enters the gas inlet pipe through the inlet port.

Simultaneously, a fan is started, and its output drives air through the connecting pipe into the mixing chamber to mix with the gas. After mixing, the ignition controller is activated to ignite the mixed gas. Heat is released through the gas nozzle, achieving grain drying. This device has a compact structure and is suitable for small-scale food drying machinery. Attached Figure Description
