Automatic Fruit Juice Processing Line 1-5T / Hour Pomegranate Juice Production Line

Description of Processing  

Raw Material selection

Choose nine mature above, no pests and diseases, no mildew, no rot of new Fresh pomegranate to ensure the quality of fruit juices.

Cleaning

Cleaning is to reduce impurities, microbial contamination, to ensure the quality of fruit juice Important measures. Soak pomegranate with water and spray or flow water
Wash. Removal of dust, impurities, microorganisms and some pesticide residues from the epidermis  For pesticide residue, can add salt solution or fatty acid system to wash
The detergent is soaked, the surface microorganism pollution is serious, usable bleaching Powder or potassium permanganate solution for immersion disinfection.

Peel and extract seeds

Because of the particularity of pomegranate fruit structure, artificial side is used at present.
Method. Cut the pomegranate peel with the knife, peel the fruit with the hand, go to the white septum Membrane, remove the grains.

Cleaning

Rinse pomegranate seeds with standard drinking water flow, remove peel Pishi left the broken epidermis and broken diaphragm and other impurities, wash away attached to
The microbes on the grains, drain after washing.

Color Protection

Soak pomegranate seeds in a color-protecting solution (e.g. citric acid, Vc, NaHS03 And so on) in case the pomegranate juice discoloration after beating. Experiments were conducted using 0.5% citric acid, 400PPMNAHS03, 0.5%VC as color protection agent, Used individually or as a composite. The color of the liquid is 3 times times the pulp weight, in the regular
After 15 minutes of color protection, beating. The test shows that the pulp is not color-protecting place In the beating process, the slurry immediately browning, placed for a period of time, Fruit paste color deepened. NAHS03 in the color protection agent, whether used separately or It is combined with other color protection agent, the best color protection effect, but will guide SO2 residue in the product is difficult to remove, affecting the quality of products, it is not appropriate to Use. VC color Protection effect can meet the actual production requirements (that is, the time

Filtration of the residue in the juice of the pulp by a plate-frame filter Press
Fruit residue.

Homogeneous

The 150〜200kg^cm2 of pomegranate juice through high pressure The quality of the machine, so that the pulp in the strong shearing force and cavitation effect
Under the broken, evenly dispersed in the sap and achieve stability. can also be used Colloid Mill for Homogeneous D concentration Pomegranate juice in the heat-resistant boiling, at atmospheric pressure at the temperature of the species , so the vacuum concentration is often used. Concentration temperature of 25〜
35C, vacuum degree of k750mmhg column.

sterilization

The homogeneous pomegranate juice is fed into the pasteurized instantaneous sterilizer for killing bacteria, sterilization temperature control in 85-92c, sterilization time of 30-50 ".

Filling Seal

Concentrated juice should be filled immediately, before filling should be the container first cleaning Sterilization, in line with hygiene requirements. The sterile filling method is available for conditional use.

Cooling

Immediately after the seal cooling, the faster the cooling of pomegranate juice The less the nutrients are destroyed. If you use a glass bottle as a container, cool
Must adopt the method of sectional cooling to prevent the glass bottle from heating uneven and burst, temperature from 80-50^ to 50-30 especially.
