The CONVERTER® MO SERIE

MO serie of Converter® comprises a range of 10 models, specifically tailor-made for any kind of waste that is not chemical, toxic, explosive or radioactive, with the possibility to choose between the sterilization and a simple disinfection. Converter® Serie MO, no matter which is the incoming waste, produces the total shredding, dehydration and the consequential weight and volume reduction of the waste, in order to have cost reduction on transport, storage and final disposal.



MO Converters have been applied to the following kind of waste:

» Animal slurry
» Slaughtering waste and animal residuals (bones, fat, meat, plumes, clogs, shells, etc.)
» Sanitary waste
» Municipal waste
» Organic
» Agricultural residuals (olive residuals, garden residuals, etc.)
» Industrial waste
» Port waste
» Expired food
» Water treatment sludge.

THE PROCESS

The Converter® technology treats waste of any provenience and composition to get simultaneously its sterilization or disinfection, physical modification, reduction of volume, dehydration and reduction of weight.
The process is patented and it covers all models because all Converter® series are manufactured under the same working principle. The peculiarity of the Converter® patent is that the waste is mechanically heated directly from its inside by means of the friction generated by material breaks, obtained by a powerful rotary blade made in Hardox, positioned on the cell bottom. All this is realized without using pressure or steam, yielding much more safety during the entire treatment process.
Thanks to the pressure reduction in the treatment cell, the evaporation temperature becomes lower allowing to obtain a final product reduced in weight and volume, totally dry and safe in less than 30 minutes. Fumes and condensate are extracted from the treatment cell and filtered in order to reduce the emissions up to zero. All Converter® machines just need water and electricity to run. With the Water Recirculation System the consumption can be lower to ZERO.


STEP 1
Waste loading :

The waste is loaded into the sterilization chamber (by hand in small machines or by means of an on-board automatic loader) in its original packaging, in plastic or cardboard bags or boxes, and the lid is closed.


STEP 2
Crushing :

The rotor starts and accelerate gradually while the material becomes finely grinded and the temperature rises quickly to about 100 °C.


STEP 3
Evaporation:

The heat generated by friction in the material causes the evaporation of the waste moisture and the temperature remains firm at the value of about 100°C.


STEP 4
Superheating

Once all the moisture has been eliminated, the frictional heat causes the temperature of the material to rise up to 151°C.




WATER RECIRCULATION SYSTEM

Basic models of Converter® condense the moisture removed from the treated waste, using a scrubber where the cooling water, taken from the net, is mixed with the vapour condensed one and discharged. As optional, to reduce the water consumption especially in the machines of big capacity, it is possible to request the condensate separation system, which keeps separate the cooling water from the vapour extracted from the treated waste and or use an existing cooling system. If the costumer hasn’t got a kind of cooling system with appropriate characteristics, there is another solution: to add a condensate separation system that suits properly. It allows to cool down and reuse repeatedly the same water reducing water consumption and also allows a remarkable reduction the quantity of liquid discharged. This necessity must be submitted with the order.
Two models of cooling unit are foreseen and OMPECO srl will choose the best one according to the customer’s site climate:


RADIATOR


The radiator-type cooler is suitable when the ambient temperature ranges between -35 and 35°C. The unit needs to be placed outdoor.


EVAPORATION TOWER


The evaporation tower-type cooler, is suitable the ambient temperature ranging between -35 and 65°C, with the condition that the wet-bulb (psychrometer) does not exceed 35°C. The unit is built in two modules: Tank module to be placed indoor and Tower module for outdoor.



STERILIZATION

The moist heat method consists to submit for a certain time the material to a temperature sufficiently high in presence of water under liquid form. The combination causes the deterioration of the enzymes and proteins of the microorganisms and, by consequence, their death and the destruction of the spores. The effect is a lot faster in comparison to the method known as “dry heat” (asking also temperatures well much higher), because in this case the mechanism of action is based on the slowest oxidization by the air of the essentials of the cells. The autoclaves are the most known devices applying the moist heat method. For a physical law, by increasing the pressure also increases the boiling point of the water that, under pressure, remains under liquid form beyond 100°C. In general, the heating can be made either with electric means or also by injecting saturated steam.
The steam, produced on site or injected, acts as vector providing the material under treatment both for the heat and the liquid water by condensation of the steam itself. Pay attention that is neither the steam nor the pressure to cause the death of the microorganisms, being the pressure only one of the ways to have liquid water at a temperature higher than 100 °C. Indeed, by the tables of the saturated steam, we can observe for example, that at the relative pressure of 1 bar (say, 2 absolute bars) the water has boiling point of 121 °C. In the Converter® equipment no pressure is used but, when the previously dehydrated material has reached the sterilization temperature set at 151 °C, the injection of water allows to keep wet the material at high and firm temperature, while restoring continuously the water and the heat subtracted for evaporation of the water itself. While continuing to warm through the rotor and at the same time to inject water, the result is that, in the same time, the material is submitted to the high temperature and presence of water under liquid form.
The Converter® machines are projected to be compliant with the strictest rules, taking as a reference the norms asking that the sterilization process should be suitable to guarantee the abatement of a microbial load conventionally fixed in N = 1012 u.f.c. (units forming colonies) for every sterilization load, with a SAL (level of sterilization safety) not lower than 10-6 (Italy, UNI norm 10384/1994, law DPR 254/2003). In general, the crushing and the dehydration are also asked, to the goals of not to recognize the waste components and for a better efficiency of the treatment, as well as the reduction of volume and weight. The Converter guarantees therefore an abatement not lower than 10-18, say 18 logarithms that is one microorganism alive every 100.000.000.000.000.000 cycles.

The reaction rate depends on the temperature, the Converter® are designed to operate on two levels of temperature:

Each treatment cycle takes place with a certain sequence: loading the waste, grinding and heating up to 100 ° C, evaporation of each liquid component, heating up to 151 ° C (or up to 121 ° C), sterilization (pasteurization) through the injection of water, maintaining the temperature for 3 minutes, lowering the temperature, discharge by the centrifugal force.
