CRIO DISHWASHER
The dishwasher is a very ubiquitous household appliance. Who possesses it, often ends up washing dishes and glasses by hands, before putting them in the basket; a situation that results in waste of time, water, and effort.
The objectives of CRIO are as follows:
1. ERGONOMICS: The location of the dishwasher: comfortable and ergonomically designed.
2. NO PRE-WASH: Replacement of hand-washing before insertion into the dishwasher.
3. SPECIFIC PROGRAMS: Choosing a program based on the level of dirt.
4. NO WATER: Limiting the use of water or exclude it entirely.
5. NO DETERGENTS: Reduce the amount of detergent or get rid of him.
6. SUSTAINABILITY: Trying to make the whole process sustainable.
7. MINIMUM DURATION: Reduction of working time programs.
The result of achieving the seven objectives is CRIO. It is the first dishwasher that works without water and detergents. What replaces the cleaning power of the water and detergent is the DRY ICE. It is ECO-SUSTAINABLE, as it does not use water, detergents and releases pollutants. It will take up less space than a dishwasher today. It will be much faster in washing and more productive. It will not be necessary to carry out a pre-wash, but on the contrary, the ceramic can be inserted directly inside of the innovative cryo dishwasher.
The term “Dry Ice” is commonly referred to as the solid-state carbon dioxide (CO2) at atmospheric pressure is at a temperature of about -79°C.
- Carbon dioxide is a non-toxic liquefied gas, inexpensive, non-communicable, and it is electrically non-conductive.
- Dry ice can maintain low temperatures. It is colorless, odorless and spore-free and is a natural part of our atmosphere.
- In the transition from solid to a gaseous state, carbon dioxide exerts bacteriostatic and fungistatic action, slowing the proliferation of microbiological time and ensuring the preservation of food in the best conditions of freshness.
- It does not leave any moisture residue on the products with which it has been in contact. By sublimating, it produces an atmosphere saturated with anhydride Carbon, which is a dry gas, tends to lower the moisture content without leaving any trace of water on the food.
- Dry ice is much denser than traditional ice, weighing about twice as much.
Dry ice blasting is a process similar to sanding, cleaning with abrasives on it.
In the cleaning process with the ice Blaster, the dry ice pellets are sprayed at the speed of sound against the surface thanks to compressed air (usually in the range from 5-7 bar). When the pellets collide with the surface (it has a temperature of -79°c) speed and temperature difference hit the surface and break it.
The pellet, therefore, can penetrate the fissures of dirt, to sublimate and take the dirt off the surface.
The effects of cryogenic cleaning are three:
Cleaning with TEMPERATURE:
The low temperature (-79 °C) dry ice in pellets creates a microthermal shock which causes the contamination between the cracks of the layer of dirty stuff. Warmer is the surface and higher is the effect.
MECHANICAL cleaning:
Dry ice pellets are pushed from the gun to a speed of 150 m/s against the surface.
Cleaning for SUBLIMATION:
Pellets penetrate the cracks of contaminants and sublime (explode) increasing their volume of 700 times.
On the side is shown the inside of Crio. On the left the detail of an arm with small nozzles. Small pellets of 3 mm diameter are released from the nozzles at high speed.
The contaminant residues fall on a tray below. These are easily removable by the user who throws the residues in organic waste.
In the image is represented the storage in which the pellets of dry ice is poured. The lid can be easily opened with a push-up closing system.
The dishes are arranged differently, one in front of the other, so that the jet can hit them both ways. The basket consists of folded L-shape, acting as a standstill for both the dishes and glasses.

CRIO DOMESTIC PELLETISER
Because Crio does not use detergent, it needs to be powered with dry ice. The domestic pelletiser is thought of as an extension of the standard refrigerator. As the American style, the light grey part serves to make ice; in this case, it produces dry ice.
Note the two carbon dioxide tanks, immediately above the drawer and the dry ice box with the overlying piston. Charging a 10 kg tank costs about € 30 because 1.5kg of CO2 produces just under 1kg of ice.
The light gray part is the drawer within which the small pellets are placed.
HOW DOES IT WORK?
The process starts with CO2 cylinders. Carbon dioxide will rise along with the black tube through the dry icebox.
With the change in temperature, as the dry ice box is located at -79° C, CO2 becomes carbonic snow.
A hydraulic steel piston surmounts the dry icebox. Intense pressure is exerted on the carbonic snow, which will become dry ice.
In turn, pushed through the extruder and with the help of a blade, small pellets will be created.
