Spray drying system PSD

for the food industryfor pasty products

Transforms liquids and pastes into powder instantly while preserving the nutritional value of the product with huge energy savings. KEY BENEFITS Atomization of products that cannot be processed in conventional dryers It can atomize products with higher viscosity, higher concentration, or products containing fibers/solids up to phew mm. Lower running cost Energy efficiency: 20-30% lower running cost than spray dryers. High final product quality Keeps the nutritional value of the products. Lower manteinance costs No nozzles or discs that have to be frequently changed. HOW IT WORKS Air is pushed inside the puise generator, around the combustion chamber. When the electric motor opens the rotary valve, air goes inside the combustion chamber. When rotary valve closes again, gas cornes into the combustion chamber. Rotary valve opens again, air goes in, and gas is ignited extremely quickly. That generates a puise, or a sonie wave, that leaves the combustion chamber through the tail pipe, together with the combustion heat, at a very strong accélération. Rotary valve closes just after ignition, and the cycle repeats. The cycle is repeated more than 100 times per second. That means that more than 100 puises per second are going throug the tail pipe. A liquid or pasty product is injected in the end of the tail pipe, through a single pipe, at low pressure. The puises break the liquid down into thousands of droplets. A hot spray of fine droplets is generated, that goes inside the drying chamber.
