Sesame seeds are widely used for tahini, sesame oil, bakery products, snacks, seasonings and other food applications. Before processing, raw sesame seeds normally contain different types of impurities, including dust, stones, plant residues, undersized seeds, damaged seeds and other foreign materials.
A suitable sesame cleaning machine helps processors remove these impurities and prepare sesame seeds for further processing. Depending on the raw material condition and final product requirements, a complete cleaning system may combine air-screen cleaning, destoning, gravity separation, grading, color sorting and other processes.
As a sesame cleaning machine manufacturer, Hebei Julite Sorting Technology Co., Ltd. provides individual cleaning equipment as well as complete grain and seed processing solutions for different raw materials and processing capacities.
Raw sesame seeds can contain different impurities after harvesting, transportation and storage. The type and quantity of impurities vary according to the growing area, harvesting method and storage conditions.
Common impurities in raw sesame include:
Dust and light impurities
Stems, leaves and plant residues
Stones and soil particles
Large and small foreign materials
Damaged or low-density seeds
Discolored or defective seeds
Simply using one machine may not remove all these materials because different impurities have different physical characteristics.
For example, air-screen cleaners are suitable for separating materials according to size and aerodynamic properties, while a destoner is designed to separate stones and other heavy impurities. A gravity separator can further separate materials according to differences in density.
For this reason, commercial sesame processing facilities often use several cleaning stages rather than relying on a single machine.
A sesame cleaning machine is equipment used to remove foreign materials and undesirable particles from raw sesame seeds before further processing.
Depending on the cleaning target, a sesame cleaning system may include several types of equipment.
An air-screen cleaner combines screening and airflow separation.
The screening section separates materials according to size, while the air system removes lighter materials such as dust, husks and other lightweight impurities.
This machine is commonly used as an initial cleaning stage because it can reduce the impurity load before the sesame enters subsequent equipment.
A sesame destoner is designed to remove stones, soil particles and other heavy materials from sesame seeds.
The separation process is based mainly on differences in density and aerodynamic behavior. This makes the destoner useful when raw sesame contains stones or other heavy impurities that are difficult to remove through ordinary screening.
A gravity separator separates materials according to differences in specific gravity.
After preliminary cleaning, sesame seeds may still contain lightweight, immature, damaged or otherwise undesirable materials. A gravity separator can help separate these materials from sound seeds when their density differs sufficiently.
A vibration grader separates sesame seeds according to size.
Size grading can be useful when processors require more uniform raw material for subsequent processing or packaging.
A color sorter uses optical detection to identify seeds with different colors or visible defects and then removes selected materials through an automatic rejection system.
For sesame processing, color sorting can be used after mechanical cleaning to help remove discolored or defective seeds that may remain after earlier separation stages.
A complete sesame seed cleaning line is normally designed according to the characteristics of the raw sesame and the required final quality.
A typical process can include:
Raw Sesame → Pre-Cleaning → Destoning → Gravity Separation → Grading → Color Sorting → Packing
The exact configuration does not have to be the same for every project.
Raw sesame seeds enter the processing line through a feeding system.
At this stage, the material may contain dust, plant residues, stones, damaged seeds and other foreign materials.
The feeding system should provide a relatively stable flow so that downstream machines can operate consistently.
An air-screen cleaner can be used to remove large, small and light impurities during the initial cleaning stage.
This stage reduces the impurity load before the material enters precision separation equipment.
The cleaned sesame can then pass through a destoner.
This stage focuses on stones and other heavy impurities that may remain after screening and air separation.
A gravity separator can be added when the raw material contains lightweight, immature or damaged seeds that differ in density from normal sesame.
The purpose is to improve the uniformity of the cleaned material before further processing.
If the project requires size classification, a vibration grader can separate sesame into different size ranges.
The grading configuration should be selected according to the required output and material characteristics.
A color sorter can provide an additional sorting stage for discolored or visually different seeds.
Julite's color sorter product line is designed for multiple grains and seeds, including sesame, peanuts, mung beans, coffee beans, chickpeas, wheat and corn. The company's listed C-series models include different channel configurations and throughput ranges depending on the material.
After cleaning and sorting, the sesame can be transferred to storage, further processing or a packing machine, depending on the customer's production requirements.
The terms sesame cleaning machine and sesame cleaning plant are related but usually describe different levels of equipment.
| Item | Sesame Cleaning Machine | Sesame Cleaning Plant |
|---|---|---|
| Scope | Individual equipment | Complete processing system |
| Application | One specific separation task | Multiple cleaning stages |
| Configuration | Single machine | Several machines connected together |
| Capacity | Depends on individual model | Designed around complete line capacity |
| Suitable for | Specific cleaning requirements | Commercial processing projects |
| Customization | Model selection | Process and equipment configuration |
A customer who only needs to remove dust and light impurities may only need an air-screen cleaner.
A customer processing commercial quantities of sesame may require a complete sesame cleaning plant combining several separation technologies.
The correct equipment should be selected according to the raw material rather than simply choosing a machine based on its name or capacity.
First, determine what impurities are present in the raw sesame.
For example, a material containing a high percentage of stones requires different equipment from sesame that mainly contains dust and lightweight plant residues.
Capacity is another important consideration.
Julite's processing demand survey divides processing requirements into ranges such as 1–5 tons per hour, 6–10 tons per hour, 11–15 tons per hour and 16–30 tons per hour. The actual machine configuration should be determined according to the raw material and production requirements.
The required cleaning level also depends on the final application.
Sesame intended for further oil processing may have different cleaning requirements from sesame intended for food products, roasting or direct packaging.
Different separation methods target different impurities.
| Impurity | Possible Separation Method |
|---|---|
| Dust | Air aspiration |
| Leaves and light materials | Air separation |
| Large foreign materials | Screening |
| Small particles | Screening |
| Stones | Destoning |
| Low-density seeds | Gravity separation |
| Different seed sizes | Grading |
| Discolored seeds | Color sorting |
This is why a complete sesame seed cleaning equipment solution should be designed around the actual raw material.
A sesame cleaning system can be configured for different production objectives.
Before oil extraction, foreign materials should be removed to reduce contamination and prepare the raw sesame for subsequent processing.
A basic configuration may include pre-cleaning, destoning and gravity separation.
Food-oriented sesame processing may require additional separation and grading stages depending on the customer's quality requirements.
A color sorter can be added when visual defect removal is required.
When sesame is sold as a finished or semi-finished food ingredient, uniformity and cleanliness can become more important.
In this case, the processing line may combine mechanical cleaning, grading and optical sorting before final packing.
A complete sesame cleaning line can combine different separation principles within one processing system.
Instead of asking one machine to remove every type of impurity, each machine performs a specific task.
For example:
Air-Screen Cleaner → Removes dust and size-based impurities
Destoner → Removes stones and heavy impurities
Gravity Separator → Separates materials by density
Vibration Grader → Separates different sizes
Color Sorter → Removes selected discolored or defective materials
This staged approach makes it easier to design the processing system according to the actual characteristics of the raw sesame.
Not every sesame processing project requires the same equipment configuration.
A small processing facility may need a compact cleaning system, while a commercial seed processor may require a higher-capacity complete line.
When selecting a custom sesame cleaning machine, several factors should be considered:
Raw sesame variety
Initial impurity percentage
Main impurity types
Required processing capacity
Desired cleaning level
Whether grading is required
Whether color sorting is required
Final product application
Available installation space
Power supply and local operating conditions
Providing this information to the manufacturer helps create a more suitable equipment configuration.
Choosing a manufacturer instead of purchasing individual equipment without process planning can be useful for projects that require multiple cleaning stages.

Raw material: Sesame seed and variety
Capacity: Required tons per hour
Initial impurity level: Estimated percentage if available
Impurity types: Dust, stones, stems, damaged seeds, etc.
Final purpose: Oil processing, food processing, seed preparation, packaging or other applications
Required cleaning level: Basic cleaning or multi-stage cleaning
Available space: Approximate workshop dimensions
Power conditions: Local voltage and frequency
Whether color sorting is required
Whether a complete processing line is required
These details allow a sesame cleaning equipment manufacturer to evaluate the appropriate equipment combination.
A sesame cleaning machine is used to remove foreign materials such as dust, plant residues, stones, unwanted particles and defective seeds from raw sesame.
Depending on the raw material, a line may include an air-screen cleaner, destoner, gravity separator, vibration grader, color sorter and packing machine.
Not every sesame processing project requires a color sorter. It is generally considered when the customer needs additional removal of discolored or visually different seeds after mechanical cleaning.
Capacity should be selected according to the required hourly throughput, raw material condition, impurity level and overall processing process.
Yes. A sesame cleaning system can be configured according to raw material characteristics, capacity, impurity types, cleaning requirements and downstream processing requirements.
Usually, different impurities require different separation methods. A complete cleaning line may therefore combine screening, air separation, destoning, gravity separation, grading and optical sorting.
A well-designed sesame cleaning machine is not simply about removing visible dust from raw sesame. Commercial sesame processing may require several separation stages to deal with different types of impurities and achieve the required raw material quality.
For projects requiring only one cleaning function, an individual machine such as an air-screen cleaner, destoner or gravity separator may be suitable. For larger processing projects, a complete sesame cleaning plant can combine several machines into one processing system.
