1. Tehnologiya:
1) Preparation of juice
2) The concentration of juice
3) Allocation of aromatics
4) Drying juice
5) Packing Powder
2. EQUIPMENT FOR DRYING:
2.1 Country - USSR
Technology:
1) Roller dryers.
Quality - bad.
Hardware: A1-RPO
- Q = 250 kg / hr (raw)
- Q = 50 kg / h (powder)
- G = 12 tons
2) vacuum dryer.
Quality - bad.
3) spray dryer.
Quality - good.
Equipment:
Luwa (Switzerland) Q = 300 kg / hour of moisture
Nema (GDR) ZTR-300 Q = 300 kg / hour of moisture
ZTR-500 Q = 500 kg / hour of moisture
Q = 1000 kg / hour of condensed milk
RS-1000 (Czechoslovakia) Q = 1000 kg / hour of moisture
G = 40t
A1-OR24 (USSR) Q = 650 kg / h of dry milk
G = 40t
4) Penosushka
- Under vacuum.
- In the atmosphere.
Quality - good.
- Foam stabilizers
- Aeration with nitrogen
- Drying on the tape.
5) freeze-drying.
Quality is good.
2.1 Country - Bulgaria
Technology:
1) Roller drying. - used
2) Spray-drying. - used
3) freeze-drying. - Perspective
4) microwave drying. - Perspective
2.1 Country - Germany
Technology:
1) sublimation. - expensive
2) Penosushka under vacuum. - used in many countries
3) Penosushka in a thin layer. - Not applicable
4) drying on rollers. - used for tomatoes
5) Drying in a moving film. - Not applicable
6) Spray-drying. - used in many countries and
provides first-class drinks
7) The method of Beers. - Not applicable - needs more height
8) microwave - drying. - Not applicable
Conclusion:
In our case it is expedient to apply the spray-drying.
For the performance of the concentrated raw Q = 1000 kg / h
we should expect H = 10 m G = 40 tons
(The height will be for a lesser performance).
