Description
Technical Field
[0001] The utility model relates to the technical field of pet food production equipment, in particular to a drying and sterilizing equipment for pet food production. Background Art
[0002] Drying and sterilization equipment in pet food production is a key link in ensuring product quality and safety. Its function is to remove moisture and kill microorganisms such as bacteria, mold, and parasite eggs to extend the shelf life of the product and ensure food safety.
[0003] Multi-layer belt drying equipment is a continuous drying and sterilization equipment commonly used in pet food production. It achieves uniform drying and microbial control of materials through the transmission of multi-layer mesh belts and circulation of hot air flow. It has a compact structure design and high production capacity. It is suitable for large-scale production of granular, flaky or block pet foods, such as dry food, baked food, jerky snacks, etc.
[0004] When using a multi-layer belt drying equipment to dry pet snacks, it is necessary to transport the formed pet snacks to the conveyor belt inside the drying equipment. At present, auger conveyors are mostly used for loading. Since the unloading range of the auger conveyor is small, the pet snacks will accumulate on a local position of the conveyor belt. In order to optimize this problem, the staff drives the auger loader to swing by installing a reciprocating rotation mechanism, and then spreads the pet snacks on the conveyor belt. Although this method solves the problem of local accumulation, the thickness of the loading cannot be controlled. Thicker pet snacks will result in poor penetration of hot air during drying, affecting the final drying and sterilization effect. At the same time, this swinging unloading method leads to increased equipment investment and use costs. Therefore, the present application provides a drying and sterilization equipment for pet food production to meet the needs. Utility Model Content

[0040] In this embodiment, as Figure 1 and Figure 2 shown, the heating component 7 is used to convey hot air into the oven 1 to dry and sterilize the pet snacks on the conveying device 2. The heating component 7 is connected to the oven 1; the heating component 7 includes a heating box 701 fixed to the bottom of the oven 1. A plurality of air supply fans 702 are fixedly connected to the outside of the heating box 701. By heating with the heat source inside the heating box 701 and cooperating with the air supply fans 702 to supply air, the heated air can be conveyed into the oven 1, and thus the drying air for drying and sterilizing the pet snacks can be provided. A heat source is provided inside the heating box 701, and the heat source is an electric, gas, coal, or steam device; the exhaust component 8 is used to discharge the humid and hot gas inside the oven 1. The exhaust component 8 is connected to the oven 1; the exhaust component 8 includes an exhaust fan 801 fixed to the top of the oven 1. A main pipe 802 is fixedly connected to the top of the oven 1. A plurality of branch pipes 803 are fixedly connected to the main pipe 802, and the branch pipes 803 are all communicated with the oven 1. One end of the main pipe 802 is fixedly connected to the input end of the exhaust fan 801. By cooperating with the exhaust fan 801, the main pipe 802, and the branch pipes 803, the humid and hot air inside the oven 1 can be discharged, and thus the dryness inside the oven 1 can be ensured, ensuring the drying effect of the pet snacks.
[0041] The working principle of the present utility model:
[0042] Air is blown into the interior of the heating box 701 by the air supply fan 702. The heat source inside the heating box 701 heats the incoming air, and the heated dry air enters the interior of the drying oven 1 for preheating. The pet snacks to be processed are conveyed to the interior of the receiving hopper 301 through the auger conveying device. The pet snacks inside the receiving hopper 301 enter the guiding hopper 4. Under the action of the flow-dispersing plate 6, the guiding hopper 4 is divided into multiple blanking channels, so that the pet snacks are laid flat and fed in the guiding hopper 4. Since the guiding hopper 4 is inclined, the pet snacks sliding downward come into contact with the leveling section 506. Under the action of the leveling section 506, the stacked pet snacks are blocked to prevent the stacked ones from falling onto the conveying device 2. When the specifications of the pet snacks are relatively large, they squeeze the leveling section 506, causing the leveling section 506 to rotate to widen the distance between the leveling section 506 and the extension plate 401, allowing the pet snacks to pass through and fall onto the conveying device 2. The protruding portion 503 can block the leveling section 506 to control the rotation amplitude of the leveling section 506. The driving shaft of the upper conveyor belt drives the cam 9 to rotate, causing the cam 9 to strike the extension plate 401. The vibrating extension plate 401 can prevent the pet snacks from accumulating on the extension plate 401, thereby assisting in blanking. The dry air entering the interior of the drying oven 1 first exchanges moisture with the relatively dry pet snacks through the lower conveyor belt, passes through the conveyor belts layer by layer upward in sequence, forms a countercurrent exchange with the pet snacks, reaches the top layer, exchanges with the relatively wet pet snacks, and the wet air reaches saturation. At this time, the exhaust fan 801, in cooperation with the main pipe 802 and the branch pipe 803, discharges the wet air to ensure the dryness inside the drying oven 1. The pet snacks are circulated and conveyed inside the drying oven 1 and dried in cooperation with the dry air. At the same time, under the action of high temperature, the pet snacks can be sterilized, thereby extending the shelf life of the pet snacks and ensuring food safety.
[0043] The present utility model covers any substitutions, modifications, equivalent methods, and solutions made to the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the following preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model even without these detailed descriptions. Additionally, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0044] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
