COMPACT, VERSATILE,
ROBUST AND HIGH PERFORMANCE.

The characteristics of the dryer - Cooler Machinery Piratininga are known for their durability, low maintenance and mainly by its high efficiency. Due to its design, the cylinder is less than that used in conventional units, thus it is necessary to half or even one third of the area occupied by conventional dryers with the same capacity, resulting in lower installation cost.

Inside the drum there is no moving parts and is virtually non-existent wear by the action of abrasive materials. The uniform drying of the product is ensured by the control system, the temperature of air is regulated by controls that use the correlation between the level of product moisture and temperature of the exhaust air.

These controllers automatically compensate for variations in moisture of the food that passes through the inner cylinder with constant and gentle aeration. With the rotation of the cylinder, the product rolls gently back on itself, and the surface of the particles come in complete contact with the heated air. This gentle handling minimizes the degradation of thin and brittle materials, this process considerably reduces the breakdown of particles and prevents the formation of dust.

The heated air entering the channel directly under the layer of product in constant motion, passing through it in an upward direction and ensuring a uniform and complete contact with the surface of the particles. The transfer of heat is gradual and positive, made by convection and helps maintain product uniformity and protection against damage by overheating.

The inside housing comic allows the product layer is less thick at the inlet end so that the larger volume of heated air passes through the point where it contains more moisture and less prone to overheating. The air cooled and saturated with moisture is drawn immediately, thus avoiding its condensation in the cylinder.

The Dryer-Cooler performs the two functions without requiring more space, reducing the processing time and handling costs. Baffles in the air channels allow the heated air and cold air are simultaneously injected through the dual air intake. Areas of drying and cooling are respectively adjusted to the process in question.

BUILDING THE DRYER - COOLER AND ITS COMPONENTS

The compact design and construction of double housing give the drum dryer - Cooler resistance unmatched. Mounted on a rigid steel that maintains a correct alignment of all rotating parts. pesquisar

On the supply support is equipped with rollers, the rollers lock and head stationary distribution, while the support of the discharge end is fitted with rear rollers. The drive is mounted on an entirely steel.

The drum rotates in hoops-piece heat-treated to prevent any kind of wear, forming a part of the cylinder body, and leaning on hardened steel rollers for tempering.
