Abstract
Description
Technical Field
[0001] The utility model relates to a screening device, in particular to a screening device for preparing bamboo shoots and rice. Background Art
[0002] With the improvement of living standards, the self-heating convenience food market has grown rapidly, and instant rice is an important product. However, highly refined rice leads to the loss of rice nutrients and reduced nutritional value. Common instant reconstituted rice products on the market have a single nutritional component. Therefore, reconstituted rice made by extruding and maturation after high dietary fiber crops are supplemented with coarse grains and nutritional supplements in proportion has broad development and application prospects. In particular, reconstituted bamboo shoot rice is mainly processed and produced with forest vegetable bamboo shoots and coarse grain brown rice. The optimal formula and process conditions of reconstituted bamboo shoot rice are optimized through single factor experiments and orthogonal experiments. It is expected that the product can enable residents to enjoy the convenience brought by convenient foods, while at the same time supplementing the daily nutrients required by consuming instant rice.
[0003] The preparation process of bamboo shoot rice is roughly as follows: raw materials → crushing → screening → adding bamboo shoot sauce → mixing → extrusion, maturation → dicing → drying → bamboo shoot rice finished product. After the bamboo shoots are crushed, the suitable finished products are screened out through a screening device for making bamboo shoot rice. The current bamboo shoot powder screening device only performs one-time screening, and the bamboo shoot powder powder with different particle sizes can easily cause the sieve holes of the screening device to be blocked, making the screening efficiency of the screening device low. Utility Model Content
[0004] The utility model aims to provide a screening device for preparing bamboo shoots and rice, mainly to solve the problem of low screening efficiency of the existing screening device.

DETAILED DESCRIPTION
[0019] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.
[0020] like Figure 1 , 2 As shown, the utility model discloses a screening device for preparing bamboo shoots and rice, comprising a primary screening mechanism 1 at the top and a fine screening structure 3 connected by a funnel-shaped feeding channel 2; the primary screening mechanism 1 comprises a primary screening box 4 with a feed inlet, a pair of mounting grooves 5 arranged on opposite sides of the primary screening box 4, a vertical slide column 6 arranged in the mounting groove 5, a screen frame 7 slidably connected to the vertical slide column 6 at both ends and driven by a cam assembly, a primary screening net 8 detachably fixed on the screen frame 7, and a stirring assembly rotatably connected to the screen frame 7 by bearings 9 and rotatably connected to the primary screening box 4 at both ends; wherein, the lower end of the primary screening box 4 is connected to the upper end of the funnel-shaped feeding channel 2.
[0021] In this example, the cam assembly includes a cam 18 fixed on the two side walls of the primary screening box 4 and driven by a motor 17, a groove 19 arranged on the screen frame 7 and adapted to the cam 18, and a return spring 20 sleeved on the vertical slide column 6 and connected at both ends to the screen frame 7 and the bottom of the mounting groove 5, respectively. Under the rotation of the motor, the cam assembly converts the rotary motion into a linear motion, so that the screen frame 7 reciprocates up and down, and vibrates the powdered bamboo shoots on the coarse screen, so that the raw materials pass through the coarse screen to the fine screening mechanism. During the up and down reciprocating motion, when the cam 8 does not apply a force to the screen frame 7, the screen frame 7 moves downward under the elastic action of the return spring 20, and the continuous rotation of the cam 18 realizes the purpose of the up and down reciprocating motion of the screen frame 7.
[0022] Another cleverness of this embodiment is that the stirring assembly includes a stirring shaft 21 with stirring blades rotatably connected to the screen frame 7 through a bearing 9, gears 22 arranged at both ends of the stirring shaft 21, and toothed grooves 23 arranged on the side wall of the primary screening box 4 for meshing with the gears 22. When the screen frame 7 reciprocates up and down, the screen frame 7 will drive the stirring shaft 21 to move upward, and through the action of the gears, the stirring shaft will show a rotating effect, thereby stirring the dried bamboo shoot powder on the coarse screen, which can accelerate the falling of the powder and improve the coarse screening efficiency.
[0023] In this embodiment, the fine screening structure 3 includes a fine screening box 10 whose feed port is connected to the lower end of the funnel-shaped feeding channel 2, a discharge port 11 provided on the side wall of the fine screening box 10, a fine screen 12 obliquely arranged in the fine screening box 10 and whose lower end corresponds to the height position of the discharge port 11, a vibration motor 13 provided on the back of the fine screen 12, a finished product collection box 14 provided below the fine screen 12, a coarse material collection box 15 provided on one side of the discharge port 11, and a finished product collection box inlet and outlet 16 provided on one side below the fine screening box 10. The dried bamboo shoot powder in the primary screening mechanism falls on the fine screen, and under the vibration of the vibration motor, the qualified powder passes through the screen and falls into the finished product collection box, and the unqualified dried bamboo shoot powder falls into the coarse material collection box through the discharge port, so as to facilitate the pulverization of the unqualified dried bamboo shoot powder again.
[0024] In another embodiment, the screen frame 7 is provided with a limit post 24, and the fine screen 12 is provided with a mounting hole corresponding to the limit post. A hinged door 25 for removing the screen is provided on one side of the primary screening box 4. By opening the hinged door, unqualified large-particle powder on the screen can be removed conveniently and quickly, and the screen can also be replaced to meet the installation of screens with different particle sizes.
[0025] Through the above design, the utility model sets a primary screening mechanism, uses the cam assembly and the stirring assembly in the primary screening mechanism to perform primary screening on the dried bamboo shoot powder as the raw material of bamboo shoot rice entering the primary screening mechanism, vibrates and stirs the damp and clumped powder to disperse it, and initially filters and screens out obvious large-size particles, which is convenient for subsequent fine screening and improves the screening efficiency of raw materials in bamboo shoot rice production. Through the two-stage screening action, the screening quality and screening efficiency of the screening device are greatly improved.
[0026] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
