Donetsk plant "Prodmash" occupies a leading
position in the market for 18 years and specializes on production
and supply of dryers to manufacture powders out of the following
products:
egg melange;
egg white and egg yolk separately;
sea weed (sodium alginate);
meat and bone broth;
blood of animals;
brewers' yeast;
medicinal preparations;
a number of dye stuff;
extracts (coniferous, willow, herbal and other extracts);
polymers (givpan, used to thicken drilling fluid in oil
production);
soy milk;
protein and milk concentrate;
pectin;
casein;
biocopolymers ( processing of waste wool, down, feathers);
other foodstuffs and materials.
We have the base for experemental dryinf jf each
liquid products.
High-efficient equipment to dry liquid foodstuffs
and materials was designed considering multiyear production
experience and utilizing the advanced technology - drying in
vibrofluidized bed of inert material that guarantees highest quality
of the products according to the international standards.
More than 1000 dryers were bought by poultry
factories of ex-USSR countries, Argentina, Bulgaria, Poland,
Thailand and Iran.
Some our references from different regions of the
world:
The facility for drying liquid food incorporates
the following: the drying chamber, product filter, metering pump,
receiving and service tanks, transfer pump, air heater-ventilation
plant and cyclones with tanks for powder collection. The drying
chamber has air-atomizing burners and a vibratory grid whicn
contains the bed of inert material grains.
Principle of operation
The filtered-off egg mass is fed by means of the
metering pump to two air-atomizing burners. There it is atomized
into the vibrofluidized bed of inert material, namely fluoroplastic
cubes with 4 mm faces. The product covering the grains surface gets
efficiently dried. Grains' collisions result in fracturing of the
film formed, the latter carried away into the cyclone and deposited
in the tank.
At present we can supply 4 standard sizes of drying
facilities to potential customers. The technical and operating data
of the driers are listed in Table

Dryers on inert materials to dry liquid foodstuffs
have a number of advantages as compared to conventional Belgian,
Danish, American, Slovak spray dryers:
double less process losses of the product (carried out by
waste air and during sanitary cleaning);
higher consumer properties of the finished product due to
large particle size of powder: this powder is looser, easily
proportioned, less consolidated and has longer shelf life. To
prove the above we would like to note that egg processing tests
were conducted in Argentina on Danish spray dryer of "Niro A/S"
and Ukrainian vibration dryer of Donetsk plant "Prodmash". As a
result of it dryers of Donetsk plant "Prodmash" were recognized as
corresponding to the requirements of the international
standards.

Price advantage:
Low metal intensity due to small dimensions of the machine;
Small occupied production areas;
Increase of production without additional areas;
Comparatively fast payback;
Guarantee for a year and a half, included in the cost of the
proposal.
Wasteless technology - drying of broken and non-standard eggs
to feed poultry.
Low requirements to the production infra-structure due to
possibility of steam air heater operation with low steam pressure
(0.3-0.4 MPa).
The drying facilities are delivered to the customer
complete with grains of inert material, and a kit of spares for
warranty period of operation.
If the customer wishes the equipment can be
produced with capacity of 300 kg/hour in terms of evaporated
moisture.
The warranty for the drying facility operation is
valid for 12 months from its commissioning date, provided the
facility is operated in two shifts. The above warranty period is
valid, provided the contract supervision, commissioning, adjustment
and alignment are carried out by supplier's experts.
The contract supervision, commissioning and
adjustment require 10-30 days.
The Customer's personnel is trained during the
contract supervision, commissioning and adjustment
work.
Principle of operation
The drying facilities are delivered to the customer
complete with grains of inert material, and a kit of spares for
warranty period of operation.
