Date is one of the important fruit crops in dry and hot regions, and is widely cultivated, especially in Iraq, accounting for one-third of the world’s total. Coconut dates are resistant to high temperatures, drought, salt alkali, frost, and moisture, and grow well in tropical to subtropical regions. In addition to providing edible fruits, its inflorescence juice can be used for sugar production, its leaves can be used for papermaking, its trunk can be used as building materials and sinks, its tree shape is beautiful, and it is often used as an ornamental plant. Coconut dates contain nutrients such as protein and minerals. Eating date palm regularly has many benefits for the body. There are over 50 varieties of date palm in the world, but the only edible one is Amari date palm, which has a bright red outer skin similar to Emperor date palm and contains high fiber. It is usually made into dried date palm for consumption, with a weight of 15-23 grams per piece.

Date Processing Line End Products And Package

Date syrup(Concentrated date juice): 70-75 Brix. PH value range 4.2-6, the date syrup does not contain any non-soluble materials, and the date juice after filtration and concentration process, the date syrup will be obtained. The date syrup is thinner than the date paste and is more concentrated in sugar. It does not contain the pulp of the dates. The date syrup can be filled into bottles, barrels.

Date Juice: The TSS is 18.5 Brix, the juice is leaching or extracted with hot water to obtain the date juice. The end products can be filled into bottles or cans as beverages.

Date Paste/puree: Fresh dates after pitting, washing, sorting, blanching, pulping, then we will get the date paste/puree, then the date paste will go through the homogenizer to get the emulsified paste. The TSS of date puree is about 35 Brix. It can be used for making drinkable date juice, smoothies. The date puree can be filled into pouches or bags.

Fresh Dry Date Vacuum Package: Fresh dates through fumigation, washing, sorting, sterilization, drying, packing by vacuuming.

Date Processing Line Technological Flowchart

Fresh dates are pitted by date pitting machine, then depitted dates washing is done by air bubble washing machines with water sprays to remove dust or other foreign materials using clean water. After washing, the dates are transferred to belt sorting conveyor to sort out the inferior, damaged products. The next step is lifting the high-quality dates to the steam blancher to soft the tissue and inactivate the enzymes of the dates. Then there are two process flow for date syrup and date paste:

–If you produce date juice and syrup, then the blanched dates will be sent to the leaching/extraction tank to extract the date juice, then the date juice will go through enzymatic hydrolysis, plate and frame filtration, ultrafiltration process to remove soluble solids to obtain clear date juice, after that, the clear date juice will be concentrated by falling film evaporator to obtain the date syrup.

–If you produce date paste, the blanched dates will be crushed and pulped by the fruit pulping machine, then the date paste will be refined by scrape refiner to remove the big particles in the paste, after that the date paste will be homogenized, degassed and vacuum filled into cans or bottles.

Process flow of coconut date cleaning and drying line

Coconut dates → selection → cleaning → drying → secondary selection → irradiation sterilization

Equipment required for coconut date cleaning and drying line:

Grading machine, date cleaning machine, date drying machine, date drying machine, roller selection conveyor.

Working principle of date palm production line

The principle of date palm production line is mainly based on the characteristics of date palm, and achieves automated processing and production of date palm through a series of process flows and processing equipment. The following are the basic principles and processes of the date palm production line:

1. Raw material reception: The date palm production line starts from receiving qualified date palm raw materials. These raw materials are usually harvested after maturity, and after preliminary cleaning and processing, they are sent to the production line.
2. Peeling treatment: The peeling process of the date palm production line adopts mechanical peeling technology to quickly and accurately remove the outer skin of the date palm. This peeling technique not only improves the efficiency of peeling, but also effectively maintains the integrity and nutritional content of the dates.
3. Cleaning and classification: The cleaning equipment and technology used in the date palm production line clean the peeled dates to remove residual skin, impurities, etc. At the same time, based on the size, color, shape and other characteristics of the dates, classification equipment is used for automatic classification, which facilitates subsequent processing and handling.
4. Sugar extraction: The date palm production line uses sugar extraction equipment and technology to extract sugar from dates. The extracted sugar can be used as an ingredient in other foods or sold directly.
5. Drying and packaging: Coconut dates extracted with sugar need to be dried to remove excess moisture and maintain their dryness, taste, and quality. Packaging according to customer needs to meet product packaging requirements and facilitate sales.

Throughout the entire jujube production process, automation equipment and technology have been widely applied, improving production efficiency and quality. At the same time, the date palm production line also adopts a strict quality control system, conducting comprehensive quality inspection and control of raw materials, processing processes, and products to ensure product quality and consistency.

Technical principle of date palm production line

The technical principle of the cleaning equipment for the date palm production line mainly uses a combination of high-pressure jet and friction cleaning methods. Specifically, the cleaning equipment mixes high-pressure gas and water to form a high-speed jet, which impacts and rubs against the surface of dates to clean impurities, soil, pesticides, etc.

The cleaning equipment mainly consists of a jet cleaning device, a friction cleaning device, and a water pump. The jet cleaning device uses a high-speed jet formed by mixing high-pressure gas and water to impact and rub the surface of dates, thereby cleaning the impurities on the surface. The friction cleaning device utilizes the frictional force between two friction pads that move relative to each other to perform friction cleaning on the surface of dates, further removing impurities and dirt from the surface. The water pump is used to provide water source and power, ensuring the normal operation of the cleaning equipment.

During the cleaning process, the cleaning equipment also adopts some auxiliary measures, such as adding an appropriate amount of disinfectant, bleach, etc., to enhance the cleaning effect and disinfection effect. At the same time, in order to ensure the quality of cleaning, the cleaning equipment also adopts an automated control system and monitoring device, which can monitor and control the cleaning process in real time.
