Integrated drying-screening device

Abstract

The invention discloses an integrated drying-screening device, which is used for drying and screening granular crop materials; the integrated drying-screening device is characterized by comprising a feeding mechanism, a drying mechanism, a screening mechanism and a control mechanism; the feeding mechanism comprises a feeding box 1 with an opening at the bottom, and is used for holding and conveying a target material; the drying mechanism is connected with the feeding mechanism, is used for drying the target material and comprises a drying chamber 3; the upper part of the drying chamber is provided with a drying chamber inlet corresponding to the opening of the feeding box, and the lower part of the drying chamber is provided with a drying chamber outlet; the screening mechanism comprises a holding box 8 corresponding to the drying chamber outlet and a screen mesh component 10 arranged at the bottom of the holding box and detachably connected with the holding box, and is used for screening the target material; the control mechanism is used for controlling the feeding mechanism, the drying mechanism and the screening mechanism.

Description

technical field [0001] The invention relates to a crop drying, screening and grading device, in particular to an integrated device capable of conveniently and quickly completing crop drying, screening and grading. Background technique [0002] With the development of the economy and the improvement of people's living standards, consumers' requirements for food are not only for food, but also for convenience, especially for sunflower seeds, dried dates, pine nuts and other snacks, people tend to buy a big , Products with well-proportioned appearance, so the products need to be divided into different grades to meet the requirements of different consumers. Taking the grading of sunflower seeds as an example, most enterprises still rely on manpower to select and classify sunflower seeds. The screening process is labor-intensive, labor-intensive, and inefficient. unstable. [0003] General crops, especially seed and fruit crops, usually need to be dried to facilitate subsequent...

Problems solved by technology

[0004] For drying and screening devices currently on the market, see Chinese patents CN103385291A, CN203399656U, CN203936028U, and CN104226603A. Although these devices have solved the drying or screening problem to a certain extent, they have the following problems: 1. The lack of a humidity measuring device is simply According to experience, change the heating distance to control the drying temperature; 2. There is often only one conveyor belt, and there is no turning device in the drying process, so the drying is not uniform enough; 3. For different sizes of screened and graded crops, the screen cannot be replaced; 4. , It simply includes the screening part or the drying part, but fails to realize the integration of the two
