The processing production line of jujube jam typically includes the following steps:

Washing and sorting: Jujube fruits are washed to remove dirt and impurities. They are then sorted based on size and quality.

Crushing and pulping: The washed jujube fruits are crushed to break down the flesh and release the juice. This can be done using a crusher or pulper machine.

Boiling and cooking: The crushed jujube pulp is transferred to a cooking vessel, where it is heated and boiled. This process helps to soften the fruit and extract the flavors.

Sugar addition: Sugar is added to the boiling pulp to sweeten the jam. The amount of sugar added can be adjusted based on desired sweetness levels.

Pectin addition: Pectin, a natural thickening agent, is added to the boiling mixture to achieve the desired jam consistency. This helps the jam set properly.

Flavoring and seasoning: Additional flavorings and seasonings, such as lemon juice, spices, or vanilla extract, may be added at this stage to enhance the taste of the jujube jam.

Sterilization and pasteurization: The cooked jujube jam is then sterilized and pasteurized to ensure safety and increase shelf life. This can be done by heating the jam to a specific temperature for a certain period of time.

Packaging: The hot jujube jam is filled into jars or containers while still hot. It is important to ensure proper sealing to maintain product freshness and prevent spoilage.

Cooling and labeling: The filled jars are allowed to cool down before labeling and packaging for distribution and sale.

It's worth noting that the processing line for jujube jam can be customized based on specific requirements and production volumes.

Product packaging: aseptic big bag / glass bottle / PET bottle / roof bag / Tetra Pak, etc

Jujube juice extracting system

The jujube extracting process is the core processing in the jujube juice and syrup prcessing line,it mainly includes two steps:hot water extrction and adding enzyme preparation for enzymolysys.The jujube juice yield rate is 55%-60% with these two methods applied.
Hot water extraction: This process is carried out in the SUS304 extraction tank,the jujube pulp and 70°C hot water ratio are 1:3 in the extraction tank,the PH is adjusted to 6.0±0.2,then start the stir to blending for 2 hours.After heating the slurry was filtered through a vibrate screen filter to remove large impurities and insoluble matters.

Enzmatic hydrolysis:Pectinase and cellulose enzyme preparations were added at the rate of 1% for each on a date pulp weight basis in the enzymatic hydrolysis tank.The mixture of date pulp,water and enzyme preparations are mixed carefully and incubated at 50±2°C for 2 hours with a continuous blending.The date juice extraction system results in a main product(date juice)and a by-product(presscake).Crude juice contains soluble and insoluble solids as well as foreign matter.

Date juice clarification system
Several technologies have been employed for clarification of date juice,such as juice pretreatment by boiling,precipitating or hydrolyzing colloids by enzyme,removing insoluble foreign matters by means of filtration or centrifugation,decolorrization using activated carboon or ion exchange,removing the minerals using chemicals or ion exchange,and removing high molecular weight compounds by foaming.The mature technology is that the jujube juice is first filtered through a plate and frame filter,and then use the ultrafiltation system to filter it twice,so that we get a clarified jujube palm juice.

Date syrup concentration system
After refining and filtration,jujube juice with soluble solid content of 20-25% will be obtained,which needs to be concentrated.The most common soluble solid content of jujube syrup is 75%.The falling film evaporator is applied to cocentrated the date juice to jujube syrup.

Date syrup filling machine
The date syrup after concentration,then cooled down to 30°C,and filling into the bottles or metal cans.As the syrup does not pasteurize,to extend the shelf life,the vacuum filling machine is suggested.
