Dates processing plant
Scope of project: EP contracting
(design + procurement + installation/commissioning + training)

|
|
|
Dates juice |
Dates juice |
Dates juice |
Dates instant powder |
Dates Biscuit |
Dates jam |
Elevator |
We can supply different height, length, width as per customer's requirements.
|
Winnowing machine |
Used to remove grass, leaves, dust etc with air suction system
|
Grading machine: Choice of roll bar type grading, drum grading, cage grading, photoelectric grading
|
1. Roll bar grading machine: Different gaps are arranged between roll bars. When raw materials pass on roll bars, materials with different sizes will fall
down to conveyor belts from different gaps.
|
2. Drum grading machine Holes with different diameters are arranged on the sieve. When materials pass through different holes, grading job is realized.
|
|
3. Cage grading machine Suitable for long shape fruits.
|
|
4. Photoelectric grading machine The system will conduct image fast processing according to fruit shape, size, color and external defect for fruit grading as per user requirements, making each grade of the fruits have the same appearance and quality. Different lanes and capacity are available.

|
Cleaning |
Bubble washing machine: Vortex pump is provided so as to create bubbles. The dates are vibrating on waves for good cleaning.
Brush roll washing machine: Used to clean hair and dirts inside the date folds.
|
Pit removing |
Date pit removing machine: Feed the dates into the inlet, the dates enter through dies conveyor, then the machine will remove the pits automatically with a capacity about 150,000 dates/hr. It greatly increases efficiency and reduces labor force.
|
Dry: Different choices like tunnel type, belt type, microwave type, vacuum type, microwave vacuum type etc are available. |

Process continued for juice processing:
Steeping / Pre-cooking →Pulping → Sterilization → Refining & Filtering →
Homogenization → Degassing → Concentration → Filling → Capping →
Pasteurization → Cooling → Labeling
Steeping tank |
Used for dates juice processing. The dates shall be crushed into certain sizes before feeding into the steeping tank. Mixer is provided for homogenization. Steeping effects rely on water filled, temperature, time and dates crushing.
|
Pre-cooking Machine |
The purpose is to sterilize and soften the dates.
|
Three Channel Pulper |
The first channel is for rough pulping, the second and third channels for fine pulping. The sieve diameters in the three channels can be selected according to the requirements of materials.
|
Sterilization |
Plate type heat exchanger used to kill pathogenic bacteria and passivate pectin enzyme and prevent precipitation.
|
Refining & Filtering |
Refining: |
1. Pectin enzyme refining |
|
2. Chitosan refining |
|
3. Ultrafiltration |
|
4. Resin absorption |
|
Filtering: To remove precipitated and suspended matters, sieving machine, and or filtering machine will be used for the purpose.
Sieving machine
Paperboard filtering machine
Diatomaceous earth filtering machine
|
|
Homogenization |
Used to crush & homogenize different particle sizes, increase delicate taste & flavor, and pectin exudation.
|
Degassing |
To remove air generated during crushing, pulping, homogenizing, prevent or reduce loss of nutritious ingredients
|
Concentration |
Dehydration equipment to desired concentration degree.
Centrifugal thin film evaporator
Three-effect-evaporator
|
Filling |
Aseptic filling
|
Capping |
|
Pasteurizer |
|
Cooling |
|
Labeling |
|
For instant dates powder process:
Choice of spray tower, belt type vacuum drier, horizontal fludized bed drier
Spray tower |
After concentration, juice drops are distributed into hot air by mister. The powder falls because of gravity after evaporation and is collected.
|
Belt type vacuum drier |
|
Horizontal fluidized bed drier |
|
