Description

Technical Field

[0001] The utility model relates to the technical field of baking ovens, in particular to a pet food hot air circulation multi-layer tunnel energy-saving baking oven. Background Art

[0002] Pet food is food specifically provided for pets and small animals. It is a high-end animal food that is between human food and traditional livestock and poultry feed. Its main function is to provide various pets with the most basic nutrients required for life support, growth, development and health. It has the advantages of comprehensive nutrition, high digestibility and absorption rate, scientific formula, quality standards, easy feeding and use, and can prevent certain diseases. Dry pet food needs to be baked during processing, but existing baking equipment often bakes directly, which is not effective.

[0003] According to Chinese patent publication number: CN219020156U, a dog food shaping and baking device is disclosed, comprising an oven body, a door panel provided on the front wall of the oven body, a baking lamp provided on the inner wall of the oven body, a motor fixedly mounted on the outer lower wall of the oven body, a motor drive end penetrating the lower wall of the oven body, and a turntable fixedly mounted on the motor drive end. The utility model supports dog food by stacking the supporting trays in the splicing assembly, and the stacking splicing assembly enables the supporting trays to be stacked and spliced, thereby realizing multi-layer simultaneous processing of dog food baking. In conjunction with the rotation of the motor and the turntable, the dog food in the supporting tray is fully baked, thereby improving the yield of dog food baking. The exhaust filter assembly absorbs, filters and discharges odors generated during the processing of the baking oven body, thereby reducing the pollution of the odor to the workstation environment. Although the addition of the reversing function improves the drying effect of the dog food, its effect is still limited. The hot air from the drying cannot be recycled. The baking method is not as effective as the flowing drying air, and a large amount of heat energy is wasted, which does not achieve the energy-saving effect. Utility Model Content

[0013] Beneficial effects

[0014] The utility model provides a pet food hot air circulation multi-layer tunnel energy-saving baking oven. Compared with the existing technology, it has the following advantages:

[0015] 1. In the present invention, by means of a circulation mechanism, the drying air inside the drying chamber is sucked into the hot air circulation chamber by the air intake fan inside the air intake pipe while drying. Then, the hot air is blown directly into the mixing chamber through the air inlet hole of the mixing chamber in the direction of the other end of the air intake pipe, and begins to dry the pet food entering the mixing chamber. At the same time, the stirring of the stirring rod ensures uniform drying. The drying air inside the drying chamber is effectively circulated to the feeding stage to start drying, making full use of the excess hot air and effectively improving the drying efficiency of the pet food. At the same time, the stirring of the stirring rod also prevents the pet food from clumping.

[0016] 2. In the present invention, through the drying mechanism, when the pet food is broken up and enters the rear drying chamber, it will first fall onto the top drying conveyor belt, and then fall onto the drying conveyor belt of the next layer when it moves to the other side. The hot air generated by the hot air blower will enter the air outlet chamber and be blown out evenly through the hot air inlet slot at random, starting to dry the pet food on each layer of the drying conveyor belt, and finally fall into the discharge port to be collected. By setting up multiple drying conveyor belts, multi-layer tunnel drying of pet food is effectively realized, which effectively improves the drying effect of pet food. Moreover, no dryer is added to each tunnel, which effectively achieves the energy-saving effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS
