Description

Technical Field

[0001] This utility model relates to the field of baking oven technology, and in particular to a raw material baking oven. Background Technology

[0002] In the processing of fishing bait, the baking oven is one of the key post-processing devices. Its core technology lies in precisely controlling temperature, humidity, and hot air to dry, cook, sterilize, activate or fix the flavor of the bait, and even promote the fermentation of beneficial microorganisms. The uniformity and precision of this process directly determine the final bait's firmness, particle integrity, flavor concentration, shelf life, and fish-attracting effect.

[0003] Currently, most bait manufacturers use traditional hot air circulating ovens, typically found in the food industry. Their basic structure consists of an insulated chamber with a central heating system and blower that blows hot air into the main chamber, heating the entire space through airflow circulation. Humidification is usually achieved by injecting steam into the main chamber through steam nozzles or ultrasonic humidifiers located in one corner of the chamber.

[0004] However, when using traditional baking ovens, the processing results of bait on different shelves within the same oven vary significantly. Because hot air and moisture enter the oven from a single source, the microenvironments of different shelves are drastically different, especially with multiple shelves. Typically, shelves near the hot air inlet and duct experience high temperatures, high airflow, and low humidity, causing the bait to easily lose excessive moisture, become dry and hard, and even scorch. Conversely, shelves further away from the duct and outlet experience lower temperatures, slower airflow, and more moisture buildup, resulting in incomplete drying, uneven cooking, and increased susceptibility to mold and spoilage. This batch-to-batch inconsistency leads to inconsistent bait quality within the same oven, severely impacting product consistency and commercial value.

[0005] Therefore, a new baking oven is needed to solve the aforementioned bottleneck problem. Utility Model Content

[0006] The purpose of this invention is to provide a raw material baking box that can achieve precise and zoned temperature and humidity control inside the baking box, and can also be adapted to material racks with different interlayer gaps.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A raw material baking oven includes a box body with an opening and closing door on one side. The box body contains multiple layers of material racks. Multiple hot air pipes and humidifying pipes are arranged in the gaps between the layers of the material racks. Each hot air pipe and humidifying pipe has a nozzle at one end and faces the opening and closing door. Each hot air pipe in each layer gap is connected to a hot air branch pipe, which is connected to a main hot air pipe. Each humidifying pipe in each layer gap is connected to a humidifying branch pipe, which is connected to a main humidifying pipe. Each main hot air pipe and humidifying pipe has one closed end and extends to the outside of the box body. The main hot air pipe is connected to a hot air source, and the main humidifying pipe is connected to a water source.

[0008] As a further feature of this utility model, both the hot air branch pipe and the humidification branch pipe include interconnected rigid pipe sections and flexible pipe sections.

[0018] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] A type of raw material baking box, reference Figures 1 to 3 The oven includes a housing 1, with an opening and closing door 11 on one side to ensure the overall airtightness of the oven when closed. Support feet 12 are provided at the bottom of the housing 1. The interior of the housing 1 is a baking space, in which a material rack 2 is provided. The material rack 2 is multi-layered, including parallel spaced material plates and support rods for connecting the material plates. Universal casters 21 are provided at the bottom of the material rack 2, allowing the material rack 2 to move freely and easily enter and exit the housing 1.

[0020] Inside the housing 1, multiple hot air pipes 3 and humidifying pipes 4 are installed in the gaps between each layer of the material rack 2. The hot air pipes 3 and humidifying pipes 4 are equipped with nozzles 5 on the side facing the material plate. Hot air and water can be blown onto the material plate through the nozzles 5, thereby achieving baking and humidification of the material. Since hot air pipes 3 and humidifying pipes 4 are installed in each gap, the baking temperature and humidity of each layer of material on the material rack 2 can be relatively uniform. Electromagnetic valves are installed on the hot air pipes 3 and humidifying pipes 4, which can be turned on and off for each layer, thereby controlling the baking temperature of the material between each layer more precisely.

[0021] The vertical projections of multiple hot air pipes 3 and humidifying pipes 4 in each interlayer gap are arranged in a cross-interval manner, which can make the distribution of hot air pipes 3 and humidifying pipes 4 more uniform, and at the same time, they will not block each other.

[0022] Multiple hot air pipes 3 in each interlayer gap are connected to hot air branch pipes 31, and multiple hot air branch pipes 31 are connected to hot air main pipe 32. One end of the hot air main pipe 32 extends to the outside of the housing 1 and is connected to a hot air source. Hot air is blown into the hot air main pipe 32 by a blower.

[0023] Multiple humidifying pipes 4 in each interlayer gap are connected to humidifying branch pipes 41, and multiple humidifying branch pipes 41 are connected to humidifying main pipe 42. One end of humidifying main pipe 42 extends to the outside of the cabinet 1 and is connected to a water source, which is pumped into humidifying main pipe 42 by a water pump.

[0024] To adapt the hot air duct 3 and humidifying pipe 4 to material racks 2 with different interlayer heights, the hot air duct 3 and humidifying pipe 4 are designed to be height-adjustable. Specifically, each layer of hot air duct 3 and humidifying pipe 4 is fixedly connected to a connecting block 71. A vertical guide column 72 is fixedly installed inside the housing 1. The connecting block 71 and the guide column 72 are slidably connected. When the connecting block 71 slides on the guide column 72, it will drive the hot air duct 3 and humidifying pipe 4 to move up and down, thereby adjusting their height. A locking bolt 73 is threadedly connected to the connecting block 71. The locking bolt 73 is perpendicular to the length direction of the guide column 72. When it needs to be fixed at a certain height, the locking bolt 73 is rotated so that one end abuts against the guide column 72. The connecting block 71 is fixed by the friction between the locking bolt 73 and the guide column 72.

[0025] To facilitate the movement of the hot air duct 3 and the humidification duct 4, both the hot air branch duct 31 and the humidification branch duct 41 are configured as two parts: a rigid pipe section 61 and a flexible pipe section 62. One end of the rigid pipe section 61 is connected to the flexible pipe section 62, which is connected to the main hot air pipe 32 and the main humidification pipe 42. The length of the flexible pipe section 62 is greater than the distance between the rigid pipe section 61 and the main pipe, so that the flexible pipe section 62 has sufficient length to accommodate the movement of the hot air duct 3 and the humidification duct 4. In other embodiments, the flexible pipe section 62 can also be a corrugated pipe or a flexible pipe, as long as it can achieve the movement of the hot air duct 3 and the humidification duct 4.

[0026] To ensure more stable movement of the connecting block 71, a dovetail groove 74 is provided on one side of the connecting block 71, and a limiting block 75 matching the dovetail groove 74 is provided on the inner wall of the housing 1. The limiting block 75 is slidably connected to the dovetail groove 74.

[0027] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
