LINEAR DRYERS FOR
HUSK AND OLIVE POMACE

WHY CHOOSE A PHYSIS DRYER AND NOT ANOTHER ROTARY DRYER?

Carmelization is a phenomenon which appears in the structure of sugars of materials that are heat treated giving a darker color to the product. Appears to the sugar content of the ketones and glucose that exists in olive pomace. Generated by high temperatures (for wet pomace over 400 Celsius degrees, releasing pigments and smell of rotten fruit. Carmelization creates a hard crust on the outer surface of the granule so the water remains trapped in the core.The common rotary dryers introduces the heat exactly in their entry that is the main entrance of the material, thereby creates a thermal shock of the olive pomace and the outer layers of the granule present the effect.  To release the trapped water in the heart of granule, requires more heat  that intensify the effect, creating a vicious circle from which the result is bad drying, enormous consumption, intolerable odors in the environment at very large distances and tanning of the material. To the conventional dryers the moisture is forwarded mixed to the material from the entry to the exit. The dry material is absorbent so mixing with moist air, absorb again the moisture creating yet vicious cycle.
THE DRYERS PHYSIS NOT PRESENT THE EFFECT OF CARAMELLIZATION
PHYSIS driers use low temperatures for drying that do not present carmelization effect. Instead provide large amounts of dry air that is the vehicle for moisture removal The dry air enters every meter of the processing path and cleared at each line. So with minimal consumption since the required heat is minimal, achieve an excellent drying result without discoloration of the pomace that maintains it's natural flavor without bad smells even in the same room of the process.
PHYSIS DRYERS  ADD VALUE TO THE MATERIAL REQUIRING  MINIMUM CONSUMPTION
PHYSIS driers use low thermal energy and large quantities of hot, dry air in which the material is agitated during the the entire duration of treatment. Moist air streams are discharged every 5 meters of path so eliminating the needs for more than the minimal fuel for thermal energy.
As mentioned the conventional dryers have enormous needs of heat using exclusively the heat to drying. Let us remind ourselves, for example, something familiar to all of us in order to understand the problem and its solution: Many times in the winter we place clothes on a radiator or near a heat source to dry them. After a long staying there drying seems impossible while the temperature the heater is often more than 70 degrees. in summertime is enough a while in the air to dry the clothes with a temperature of 30 degrees. On days with lower temperatures but more windy the clothes dry very quickly. This is because it is not enough using high temperature but also the air which is the vehicle that transports away the moisture from the materials
By drying of the olive pomace various chemical compounds are generated due to heat, light and oxygen.  These are basic compounds with a pH between 3 and 10. In the first stage takes place the isomerization of sugars having oxidative effects and the contained enzymes create electrolytic effect so only a few and special materials resist such conditions.
PHYSIS dryers are manufactured entirely of stainless steel AISI 316 and thicknesses that are resistant to these conditions.
They have appeared on the market several "manufacturers" who try to imitate the patented drying system PHYSIS and to lure and trick the professional with a lower prices, using unsuitable materials procured from low reliability markets, constructing machines that are totally unsuitable for this use.

The large amounts of heat at the conventional rotary dryers emits large volumes of flue gas. Besides the smell of scorched material (see carmelization), emit odors and smoke in large quantities that make them undesirable in any area, even far away from residential zones. It is common the fire of the material due to the direct introduction of the flame in the drying chamber and too high temperatures.
PHYSIS dryers not emit any kind of pollutant. Smells are not present in the environment. The chimney leaves only the steam which may be condensed also so to be discharged only water from the condenser.  I case of differnet materials optional equipment can be installed to drive the flow gases in an incineration chamber.
ABLE TO TREAT  BIOMASS OF ALL KINDS. SUITABLE FOR OLIVE POMACE BY THREE OR TWO PHASES PROCESSING. SEPARATES PULP BY THE HUSK.  PRODUCT OF EXCELLENT QUALITY WITHOUT CHANGING COLOR OF THE MATERIAL AND WITH THE FLAVOUR OF OLIVE. NOT EMITES ANY KIND OF POLLUTION OR SMELLS AT THE  ENVIRONMENT. THE DRYERS PHYSIS IS THE ADDITIONAL VALUE OF YOUR'S WORK AND THE SOLUTION OF THE RESIDUES DISPOSAL. WITHOUT FIRE RISK.
