Automatic Dates Palm Fruits Washing Grading Processing Line

The fully automated Date Palm Fruits Washing, Drying, and Grading Processing Line is a custom-built, fully automated production line specifically designed for dates. This integrated washing, drying, and grading process transforms harvested dates, often laden with dirt, impurities, moisture, color variations, wrinkled, or damaged skin, into high-quality, clean-looking, consistent products ready for packaging or export. This line addresses the thin skin, sticky sugar content, wrinkled skin, and susceptibility to mold and mildew caused by retained moisture in dates. The washing and drying process thoroughly removes dust, sugar stains, and sugar deposits without damaging the skin or compromising its natural color and nutritional value. Its goal is to enhance product hygiene, safety, consistency, and market competitiveness.

It is an ideal choice for date growers, date processing plants, exporters, and food processors, particularly for exporting to markets with stringent hygiene and appearance standards, such as the EU, the US, and the Middle East.

Dates Plam Frutis Washing Processing Working Flow

Collection / Loading → Elevating / Hoisting → Bubble Washing → Brush Washing / Spray Washing → Surface Moisture Removal / Air Drying → Grading / Size & Quality Sorting → Packaging / Finished Product

Dates Fruits Processing Line Key Equipment List

Elevating/Hoisting: Harvested dates are transported to the washing stage via an elevator or conveyor system to remove large impurities and prepare for the washing process.

Washing: This typically involves bubble washing, brush-roller/hair-roller washing, and spray rinsing to thoroughly remove surface impurities such as dirt, dust, pesticide residue, and sand.

Draining/Draining/Preliminary Air Drying: After washing, the surface moisture of the dates is removed using conveyor belts, spinners, or natural gravity and tumbling to help remove most of the moisture, preparing them for the dryer or hot air drying stage.

Drying/Air Drying: Using hot air circulation drying technology, temperature and humidity are controlled to effectively reduce the moisture content of the dates while maximizing the preservation of their natural color, flavor, and nutritional content.

Grading/Sorting: The dates are sorted based on size, shape, and appearance (including scars, 变色, and cracks). Mechanical roller grading, mesh belt grading, photoelectric/visual inspection sorting, and other methods are available.

Packaging Preparation/Shipment (Optional)
After grading, the dates are sent to the packaging area, where they may be sorted, quality-checked, packaged, and even labeled before being prepared for shipping or distribution to the market.

Dates Palm Fruits Processing Line Features

Food-Grade Stainless Steel Construction
All components of the line that come into contact with the dates are constructed from SUS304 or higher-grade food-grade stainless steel, which is corrosion-resistant, easy to clean, and unlikely to harbor bacteria or odors.

Adjustable temperature/humidity control and gentle cleaning methods
Bubble and brush washing, combined with spraying, can be washed with heated or warm water. The temperature and water flow intensity are adjustable to suit the tolerance of different date varieties and maturity levels.

High Automation and Continuous Operation Capability
The seamless process of conveying, cleaning, drying, and grading reduces manual intervention and allows for continuous operation day and night. The grading system supports multiple grades, allowing for quick changeover.

Low-Temperature Air Drying and Energy-Saving Design
The drying stage utilizes either air circulation or countercurrent drying to maintain low temperatures, preserving the fruit’s flavor and nutrients. The fan and heat source are designed to be energy-efficient and low-noise.

Dates Fruits Washing Processing Line Advantages

High Efficiency and Labor Savings
The entire process is automated, reducing manual intervention in the cleaning and grading stages. Processing speed is several times faster than traditional manual processing, significantly reducing labor costs.

High Product Quality Consistency
Standardized grading of jujube fruit skin, color, size, and shape ensures a uniform appearance across each batch, meeting the stringent grading requirements of export and high-end markets.

Hygiene and Safety/Reduce Damage
Using food-grade stainless steel, the cleaning process is gentle, and the drying process is conducted at low temperatures and ventilation, minimizing heat damage and discoloration. A combination of brushing and air rinsing removes surface stains even deep into wrinkles.

Energy Saving, Environmental Protection, and Resource Conservation
Some machines utilize a circulating water system, spray water recovery, heat recovery in the air drying design, or low-temperature air drying to reduce water and electricity consumption.

Dates Processing Plant Benefits

Improved Market Competitiveness
When exporting or entering supermarkets/boutiques, consistent grading and appearance are paramount for customers. Clearly graded dates command higher prices.

Reduced Product Loss
Automated grading prevents losses caused by accidental damage, crushing, or missed grades during manual grading; cleaning and drying processes reduce damage caused by mold, water stains, or bacterial residue.

Shortened Production Cycle/Increased Capacity
Continuous automated processes significantly shorten the cycle from raw materials to finished products, enabling manufacturers to respond more quickly during peak seasons or with large orders.

Meeting Food Safety/Export Standards
Using food-grade materials, clean and traceable cleaning, thorough drying, and clearly graded dates facilitates compliance with HACCP, ISO, and the sanitation standards of various importing countries for agricultural products. This is crucial for companies interested in exporting or building their brands.
