Description

Technical Field

[0001] The utility model relates to the technical field of earthworm protein processing, in particular to a low-temperature baking oven with uniform drying. Background Art

[0002] Drying is an indispensable part of the earthworm protein processing process. It is of great significance for maintaining the activity of earthworm protein, improving quality, facilitating processing and storage, and meeting hygiene standards.

[0003] In order to improve the uniformity of drying, the current oven usually preheats the oven before placing the items to be dried to ensure uniform temperature in the oven. However, even if the oven is preheated, if the items to be dried are not placed in an orderly and reasonable manner inside the oven, the items will still not be heated evenly, especially for earthworm protein, which is generally stacked together during drying. On the one hand, static placement is not conducive to the spreading of earthworm protein, and the earthworm protein stacked inside is not heated evenly. On the other hand, the oven usually takes in air from one direction and then flows out from the opposite side of the air inlet direction. In this way, the drying effect of the earthworm protein close to the air inlet side will be better than the drying effect on the air outlet side, resulting in low drying uniformity. Utility Model Content

[0004] The purpose of the present invention is to provide a low-temperature baking oven with uniform drying, so as to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides a low-temperature baking oven with uniform drying, comprising a box body and a plurality of placement boxes placed in the box body;

[0006] A partition frame is provided in the box body, which divides the inside of the box body into a material area and a working area. The working area is "concave" shaped, and the material area is provided above the working area.

[0007] There are two sets of drying components in the working area, which are mirror-symmetrical with respect to the material area.

[0008] An exhaust fan is installed on the top of the material area, and an air guide fan is installed on the top of the working area;

[0009] When the two drying components are working, they generate opposite drying airflows, which converge in the working area and are discharged from the top of the box from bottom to top.

[0010] Furthermore, the drying component includes an air intake fan and a heating wire that cooperates with the air intake fan. The heating wire generates heat when working, and the air intake fan blows the heated air flow into the material area.

A metal grille 24 is fixed on the bottom plate to ensure smooth passage of airflow.

[0030] The partition frame 14 divides the interior of the box 1 into a material area and a working area. The working area is "concave" in shape, and the material area is arranged above the working area. The working area consists of a drying area located on both sides of the material area and a transmission area located below the material area. The drying area is connected to the transmission area. Two groups of drying components are arranged in the working area. The two groups of drying components are mirror-symmetrical about the material area. The drying components are arranged in the drying area. An exhaust fan 10 is installed at the top of the material area, and an air guide fan 16 is installed at the top of the working area. When the two drying components are working, opposite drying airflows are generated. After the airflow converges in the working area, it is discharged from the top of the box 1 from bottom to top.

[0031] See Figure 2The drying component includes an air intake fan 11 and an electric heating wire 13 that cooperates with the air intake fan 11. The electric heating wire 13 generates heat when working, and the air intake fan 11 blows the hot air flow into the material area. A driving component for driving the two air intake fans 11 and the air guide fan 16 to rotate is provided in the transmission area. The driving component includes a driving motor 6 fixed to the bottom of the box 1. The driving end of the driving motor 6 is connected to the transmission shaft 7 through the bevel gear set 17, and the driving motor 6 is connected to the air guide fan 16 through the bevel gear set 17. The air guide fan 16 is fixedly connected to a mounting shaft, and the mounting shaft is rotatably connected to the bevel gear set 17 through a bearing and is composed of three bevel gears.

The handle is convenient for people to hold and easy to operate. At the same time, after multiple placement boxes 9 are connected together by the connecting strip 22, controlling the tilt of the placement box 9 at the bottom can drive multiple placement boxes 9 to tilt synchronously, which is convenient for spreading earthworm protein.

[0034] See Figure 2 and Figure 4The transmission shaft 7 is also provided with a material leveling component that conflicts with the placement box 9 to tilt the placement box 9. The material leveling component includes two eccentric wheels 8 fixed on the transmission shaft 7. There are two push rods 18 slidingly inserted at the bottom of the partition frame 14. The bottom end of the push rod 18 conflicts with the eccentric wheel 8. When the eccentric wheel 8 rotates, the push rod 18 will slide back and forth vertically relative to the partition frame 14. When the transmission shaft 7 rotates, the push rod 18 will conflict with the placement box 9 to make the placement box 9 tilted periodically. The placement box 9 can complete the cyclic motion of raising the left side-horizontally-raising the right side-horizontally by rotating the transmission shaft 7 once. The earthworm protein placed in the placement box 9 can continuously adjust its position, which is beneficial to avoid uneven drying of the earthworm protein that occurs when it is stacked for a long time.
