Chick Peas Cleaning Solution

一、What problems might be encountered in the cleaning and processing of chick peas ?

When chick peas are freshly harvested, they contain a lot of impurities, such as straw, bean stalks, broken stems and leaves, soil clods, pebbles, sand, grass seeds, weeds, etc. There are also shriveled, moldy, worm-eaten and broken beans, which vary in size and weight, making it difficult to sort them out completely in one go.

1、Cleaning machine operation-related issues.

● Insufficient screening and classification:

Improper selection of screen mesh size, unreasonable inclination angle of the screen surface, and inappropriate vibration frequency all contribute to the leakage of large impurities, incomplete cleaning of small impurities, and failure to separate good beans from crushed beans and grass seeds. Insufficient screening and classification.

● Equipment blockage, material clogging:

The long stalks of straw got entangled in the feed inlet, the screen, and the hopper of the elevator; the damp chick peas stuck to the inner walls of the equipment and the pipelines, causing poor material discharge and machine blockages, which required frequent shutdowns for cleaning.

2、Quality and mold/pest infestation issues

●  Mold spots and rotten beans are difficult to remove:

The naked eye and ordinary screening methods cannot accurately distinguish slightly moldy or internally infested chick peas. If these are mixed into the finished product, they will affect storage and food safety.

●  Fungal growth and spoilage:

Due to the accumulation of materials during processing with poor ventilation and excessive moisture content, the chick peas that have accumulated will heat up, resulting in rapid moisture absorption, mold growth, and color changes within a short period of time.

3、Problems related to processes and production operations

● Inconsistent feed volume:

Fluctuating between excessive and insufficient. When the equipment is overloaded, the sorting accuracy significantly decreases; too little feed results in waste of production capacity and low cleaning efficiency.

● The process sequence is unreasonable:

The order of initial cleaning, wind selection, screening, stone removal, and classification is incorrect. The fine processing is carried out after the initial cleaning, which results in a large amount of impurities wearing down the equipment and increasing the wear of the screen mesh.

What cleaning machine do chick peas importers usually use?

To remove impurities such as stalks, shredded leaves, soil clumps, stones, and moldy beans from chick peas , importers generally adopt a multi-stage combined approach of "initial cleaning → stone removal → magnetic separation → specific gravity measurement → polishing → grading → color sorting → dust removal".The main machine includes the following categories:

1、 Chick Peas Air Screen Cleaner

Function: Can remove large particles (such as straw, leaves, etc.), small particles (such as weed seeds) and light impurities (such as dust, empty shells).

2、 Chick Peas Gravity De-stoner

Function:  It can remove small stones similar in size and weight to chick peas .

3、 Chick Peas Gravity Separator

Function: Remove unripe chick peas , infested chick peas  and moldy chick peas  kernels.

4、 Chick Peas Polishing machine

Function: Clean the dust, mud spots and loose soil off the surface of the chick peas  to ensure they have a uniform, smooth and shiny color.

5、 Chick Peas Color Sorter

Function: It can quickly detect color changes, mold, glass and plastic impurities in chick peas  and precisely remove them.

6、 Chick Peas Dust System

Function: It can remove light impurities and dust; prevent the workshop from being contaminated and prevent dust from adhering to the surface of chick peas .

7、 Chick Peas Packaging Scale

Function:  Automatic weighing (10–50 kg/bag), bag sewing / heat sealing.

How can the purity of chick peas be improved through the use of cleaning machine?

By combining multiple devices, parameter matching and process technology, dust, straw, grass seeds, stones, soil clumps, shriveled beans, broken beans and moldy beans in chick peas are removed layer by layer, transforming raw beans into high-purity refined beans.

1、 Chick Peas Pre-cleaner:Remove large impurities

The first pretreatment step involves screening out large straws, big clumps of soil, ropes and large debris to reduce the load on subsequent equipment, prevent machine blockages and lay a foundation for the subsequent thorough cleaning.

2、 Chick Peas air screen cleaner:Remove large and small impurities, as well as light impurities.

The chick peas  air screen cleaner removes light impurities, bean shells, broken grass, dust, small impurities, broken beans and shriveled beans through air separation and screening, initially improving the cleanliness..

3、 Chick Peas Gravity de-stoner:Remove the chick peas  Stones

The chick peas  destoner is specifically designed to remove stones that are stuck together and cannot be removed by the air sieve. This significantly reduces the stone content and improves the purity for edible use.

4、 Chick Peas Gravity Separator:Remove substandard and damaged chick peas .

Based on the differences in the fullness and density of the chick peas , they are classified. At the same time, the shriveled, infested and damaged chick peas  are removed.

5、 Chick Peas Magnetic Separator:Removing Clods of Soil from chick peas

The chick peas  magnetic separator uses magnetic force to remove soil and soil clumps. It is mainly used to remove soil from chick peas .

6、 Chick Peas Color Sorter:Precisely removes moldy, blackened, and discolored chick peas .

The chick peas  color sorting machine remove moldy chick peas  , discolored chick peas  , impure chick peas   of different colors, and chick peas  of different varieties. Ensure that the products meet the national standards with high purity and no damaged chick peas  .

7、 Chick Peas grading machine

The chick peas  grading machine sorts the chick peas  by particle size, separating large particles, normal particles, small particles, and broken pods.

From raw chick peas  to finished refined beans, various levels of impurities are removed step by step. The major impurities are cleared first, then light impurities are removed by air, heavy impurities are removed by sieving, irregular beans are sorted, and damaged beans are selected. The purity gradually increases.

二、What technical problems exist in the chick peas cleaning production line?

1、The problems caused by chick peas  raw materials

Impurities are complex and difficult to separate: they contain long stalks, soil clumps, boulders, crushed bean skins, and moldy particles. A single sieve hole is unable to meet all requirements, resulting in small particles being lost, large particles being mixed in, and a decrease in sieve separation accuracy.

2、Selection equipment structure and process challenges

Both impurity removal and particle size classification are required. A single piece of equipment cannot handle both at the same time. When connected in series, there is a risk of transportation damage and seedling injury. The long stalks, weeds and hemp ropes in chick peas  are prone to entangle the elevator, the sieve shaft, the sieve surface, resulting in poor material feeding, blockage of the sieve surface and interruption of the production line.

3、Production operation and commissioning challenges

The feed flow is unstable and the parameter adaptation relies on experience. Different types of chick peas  from different origins, with varying levels of dryness and size, require re-adjustment of sieve holes, air volume, amplitude, and inclination angle. There is a lack of adaptive intelligent regulation, making it difficult for beginners to operate.

4、The overall integration problem of the production line

After the initial cleaning, upgrading, wind screening, and stone removal processes are connected in sequence, the conveying speeds at the beginning and end are not coordinated, resulting in blockage, overflow, and accumulation of materials. The chick peas  have a lot of dust during the sorting process, and the dust removal design of the ventilation duct is unreasonable, resulting in excessive dust in the workshop.
