Description

A ginkgo drying and screening device

technical field

The invention relates to the field of ginkgo processing devices, in particular to a ginkgo drying and drying device.

Background technique

Ginkgo seed stone, also known as ginkgo, is composed of outer testa, middle testa, inner testa and seed kernel. The fleshy outer testa is usually removed by soaking after the ginkgo is picked from the tree before storage. The middle seed The skin is mainly a core shell composed of cellulose and hemicellulose, and the shelling of ginkgo must be carried out before further processing.

And the quality of ginkgo nuts processed by existing shelling equipment is poor, the shelling rate of ginkgo is low, the damage loss of nuts is relatively large, and the separation of shells and kernels is not complete. Therefore, the shelling of ginkgo is the technical bottleneck in the deep processing of ginkgo. After long-term practice, it is found that the main reasons for the difficulty in shelling ginkgo are: 1. The size of ginkgo is not uniform, and the larger seeds may be crushed by the shelling machine , causing the seed shell and seed kernel to stick together and not easy to separate; the smaller seeds pass through the shelling device without shelling, and the purpose of shelling cannot be achieved, and it is also difficult to screen out after mixing with the seed kernel. 2. The humidity of the ginkgo fruit is relatively high during the shelling process, and the fruit and the fruit adhere to each other, making the processed ginkgo nuts dirty.

Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in Fig. 1 and Fig. 2, a ginkgo drying and screening device according to the embodiment of the present invention includes a box body 1, and a multi-layer shelf 2 is arranged in the box body 1, and the shelf 2 is supported on the Between the opposite side walls of the box body 1; screening holes 23 are respectively arranged on the shelf 2 on each floor, and the screening holes 21 of the shelf 2 from top to bottom gradually become smaller; At least one baffle plate 3 on the upper side of the shelf 2, the bottom of the baffle plate 3 has a set distance from the shelf 2, and the baffle plate 3 slides on the upper side of the shelf 2 driven by the driving device , and the initial position of the baffle 3 is close to the side wall of the box 1; the top wall of the box 1 is provided with a feed port 11, and the feed port 11 is arranged near the The top wall at the initial position of the baffle 3 ; also includes a drying air duct 4 communicating with the box body 1 .

After the ginkgo enters the box body 1 from the feed port 11, the driving device controls the baffle plate 3 to slide horizontally, spreading the stacked ginkgo from one side to the other, and the smaller ginkgo falls into the bottom through the screening hole 23. One layer, each shelf 2 can obtain ginkgo fruits of uniform size; at the same time, the box body 1 is connected to the drying air duct 4, which can be directly dried in the box body 1 to avoid directly shelling the wet ginkgo fruits Addresses issues that cause soiled kernels. At the same time, since the screening holes 21 on the shelf 2 can divert the water to the bottom layer, it can improve the drying efficiency.

When the feed is large, it is difficult to arrange a baffle plate 3 to lay the ginkgo fruit flat; at the same time, one slip cannot ensure that the smaller ginkgo particles pass through the screening holes completely; Two baffles 3 are provided, and the initial positions of the two baffles 3 are respectively attached to opposite side walls of the box 1 . In this way, the baffle plate 3 on the left will gradually flatten the ginkgo fruits piled up to the baffle plate 3 on the right side, and then return to the initial position; the baffle plate 3 on the right side will continue to slide to the left side; The repeated sliding of the board 3 can make the ginkgo fruits with smaller particles fall from the screening hole 21 to the next layer of shelf 2 .

As shown in Figure 3, the drive device includes a drive motor 61 and a screw nut transmission structure, the baffle plate 3 is fixedly connected to the nut 63, the output shaft of the drive motor 61 is fixedly connected to the lead screw 62, the screw The bar 62 is rotatably connected to the two side walls of the box body 1 .

The upper and lower sides of the side wall of the box body 1 are respectively provided with an air inlet and an air outlet, and the air outlet end of the drying air duct 4 is connected to the air inlet of the box body, and the drying air duct 4 includes an air duct A main body 41 , a heater 42 and a fan 43 are arranged in the air duct main body 41 . The present invention adopts a direct row drying system with high drying efficiency, and can control the air intake volume and air intake temperature of the cabinet 1 by controlling the working time of the heater 42 and the rotational speed of the fan 43, and the control is simple and reliable.

Specifically, several layers of supporting structures for supporting the shelf 2 are molded on the box body 1 .

As an implementation, as shown in FIG. 1 , the supporting structure includes supporting ribs 5 arranged on opposite side walls of the box body 1 , and the shelf 2 is arranged on the supporting ribs 5 .
