Description

A sesame cleaning device

technical field

The utility model belongs to the technical field of machinery and relates to a sesame cleaning device.

Background technique

Sesame is an important high-quality oil crop and an agricultural product for exporting foreign exchange in my country, and it is also one of the dominant crops for the development of my country's agricultural export-oriented economy. The perennial planting area of sesame in my country is about 12 million mu, accounting for 12% of the world's total area, second only to India, Sudan and Myanmar, but the annual total output is about 750,000 tons, accounting for 25% of the world's total output, ranking first in the world. Sesame trade has a strong competitive advantage. However, there are still some outstanding problems in the production and processing of sesame in our country, which seriously restrict the development of sesame industry.

In terms of production, our country still uses farmers as the unit of scattered planting. There is no rational layout in production, and there are many, chaotic, and miscellaneous varieties. Different varieties are mixed and purchased, which eventually leads to poor consistency of sesame products and poor product quality; poor specificity of raw materials, Lack of high-oil, high-protein, large-grain and other special-purpose sesame varieties, the sesame products produced are extremely disproportionate to market demand, sesame production cannot meet the needs of large and medium-sized processing enterprises, and processing enterprises cannot obtain large quantities of high-quality raw materials. Affect the quality of processed products and processing efficiency. Secondly, the major sesame producing areas in my country suffer from severe waterlogging and lack of new varieties of sesame with high disease resistance and waterlogging resistance, resulting in low and unstable sesame production, large differences between years, and no guarantee of raw material supply. Thirdly, the cultivation management is extensive, and the production lacks a high-quality and high-yield standardized planting technology system. In addition, the use of a large amount of chemical fertilizers and pesticides in the production process has brought certain chemical residues to the finished sesame, which has caused the product to fail to meet the export standard, and the gap between the pollution-free food standard is even greater, which directly affects the international competition of Chinese sesame. force.

The worse the quality of raw materials, the more problems there are, and the more the cleaning and selection process in post-processing will be tested. Raw material cleaning and processing is mainly to remove yellow spots, soil clods, stones, insect droppings, grass seeds and other foreign matter.

At present, the cleaning and processing technology of sesame raw materials in my country is still quite backward, and there are mainly the following problems:

1) The separation method is too simple, most of which are ordinary sieving and stone removal, and often only single impurities can be removed.

2) Lack of systematic combination or unscientific combination, high turnover of sesame seeds, resulting in damage and peeling of most sesame seeds, which destroys the quality of sesame seeds. At the same time, oil powder sticks to pipelines and equipment, affecting the service life of equipment.

3) The equipment is not airtight, causing dust and yellow light to fly everywhere in the workshop and factory area, and the production environment is poor, which seriously damages the health of operating workers.

4) Low production capacity, high energy consumption, even duplication and waste, unstable product quality or failure to meet the requirement that the impurity content is less than 0.5 wt%.

Contents of the invention

Based on the above problems, the utility model provides a sesame cleaning device.

In order to achieve this purpose, the technical solution adopted by the utility model is: a sesame cleaning device, including three sets of separation systems, wherein the first set of separation systems consists of a wind separator, a linear vibrating screen, and a linear vibrating screen arranged from top to bottom and connected in sequence. , specific gravity destoner, and plane rotary screen; the second group of separation system is composed of specific gravity destoner and linear vibrating screen in sequence, and the specific gravity destoner is set above the linear vibrating screen; the third group of separation system includes color sorting machine; every two adjacent groups are connected with a wind hoist.

The color sorter is provided with a finished sesame discharge port and a defective sesame discharge port, and the defective sesame discharge port is connected with the magnetic separator.

The screen mesh of the linear vibrating screen is a woven mesh, and the size of the screen surface is 1 meter wide and 2 meters long.

The linear vibrating sieve, the specific gravity destoner, and the plane rotary sieve are provided with a dust collection hood, and the air outlet above the dust collection hood, the air separator, and the air outlet of the wind hoist are all connected with dust conveying pipes, and the dust conveying pipes There is a ventilator on it.

The device also includes another wind lifter, the discharge port of the wind lifter communicates with the feed port of the winnowing machine, the air outlet of the wind lifter is connected with a conveying pipeline, and the pipeline is provided with a filter and ventilator.

The combination of each part of the utility model is scientific and the layout is reasonable, so that the whole cleaning process is very smooth, the number of turnovers of sesame seeds is small, and the production efficiency is greatly improved. Ordinary screening is used in conjunction with various methods such as color separation and magnetic separation, and cleaning and grading are carried out at the same time, which provides convenience for the targeted deep processing of sesame in the later stage. The lifting is changed from the original bucket lifting to wind conveying, which reduces the damage rate and reduces the blockage. The improvement of the sieve surface sieve makes the cleaning speed of the sesame faster, and the damage rate is low and can be kept below 0.2wt%, which greatly improves the yield and quality. At the same time, the device also adds dust collection facilities to purify the working environment to ensure the physical and mental health of the operating workers.
