information

The jujube jam processing production line involves a series of production steps, including the selection of raw dates, pretreatment, boiling, pulping, seasoning, sterilization, filling, sealing, inspection, packaging, etc.

The following are the main technical points and processes of the production line:

Raw material selection and pretreatment: • Select high-quality red dates that are mature, free from pests and diseases, and free from mold as raw materials Cleaning: Thoroughly clean the soil and impurities on the surface of red dates with flowing water De nucleating: Remove the pits from red dates by using a de nucleating machine or manual de nucleating Soaking: Soak the pitted red dates in clean water to soften and facilitate subsequent processing Boiling and beating: • Heating and boiling: Put the processed red dates into a large boiling pot, add an appropriate amount of water, and simmer over low heat until the red dates are soft and tender.

• Beating: Use a beater to beat cooked red dates into a delicate paste, and adjust the degree of beating as needed to obtain the desired jam consistency Seasoning: According to the product formula, add sugar (such as granulated sugar, honey, etc.), lemon juice or vinegar (to adjust acidity), spices, etc. to the jujube paste for seasoning, improving taste and flavor.

• Sterilization and cooling: • Sterilization treatment: High temperature instantaneous sterilization (HTST) or ultra-high temperature sterilization (UHT) technology is used to ensure the food safety of jam and extend its shelf life Rapid cooling: After sterilization, quickly cool to a suitable temperature to prevent excessive heat treatment from affecting flavor and nutritional value.

• Filling and sealing: The automatic filling machine quantitatively pours the cooled jujube sauce into pre disinfected glass or plastic bottles Then proceed with sealing to ensure sealing and avoid secondary contamination Inspection and packaging: • Conduct quality inspections on the filled finished products, including appearance, taste, microbiological indicators, etc Using automated packaging lines for external packaging may include steps such as labeling, boxing, and wrapping, ultimately forming a sales unit.

• Warehousing and logistics: The packaged jujube jam is stored in the warehouse, sorted and boxed according to order requirements, and delivered to retailers or directly to consumers through cold chain logistics. Throughout the production process, emphasis is placed on hygiene control, quality monitoring, and efficiency optimization to ensure the quality and safety of jujube jam products.

In addition, with technological progress, the application of automation and intelligent technology is becoming increasingly widespread, such as using intelligent control systems to monitor production parameters, using robots for material handling, etc., in order to improve production efficiency and reduce labor costs.

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.
