摘要:
A low pressure blower operated airknife having a housing with an elongated primary air discharge orifice for directing a narrow width curtain of air. The airknife includes an air-augmenting shroud which defines auxiliary discharge orifices on opposite longitudinal sides of the primary air discharge orifice such that air discharging from the primary discharge orifice creates a low pressure condition adjacent the auxiliary air discharge orifices for drawing additional air through the auxiliary discharge orifices which augments the velocity and volume of the discharging air current without the necessity for increasing the air inlet pressure or blower size. The shroud may take alternative forms, including pairs of wings disposed on opposite sides of the primary discharge orifice or hollow structures that surround the airknife housing. The airknife further is adapted for low pressure direction and application of air laden particles, such as preatomized liquid particles.

摘要:
A method and apparatus for impingement of fluid onto a moving surface. The apparatus includes an asymmetric slot nozzle having an opening formed between an upstream wall and a downstream wall. The nozzle is disposed generally adjacent the surface onto which the fluid is to be impinged forming an impingement distance between each of the walls of the nozzle and the surface. The impingement distance of the upstream wall is greater than the impingement distance of the downstream wall such that at least a portion of the fluid is delivered through the nozzle in a direction that is counter to the machine direction.
摘要:
An emptying unit for recovering bottom residue, particularly in drying filters, drying units and the like, comprising, inside a container for treating and containing dried product, fluid introducing elements for moving the bottom residue of the dried product. A discharge port being also provided which is controlled by a discharge valve interposed on a pneumatic circuit suitable to produce a circulation of fluid in output from the discharge port.

An adjustable deckel profiler is disclosed, for use in apparatus for drying a moving paper web. The profiler is a slidable member which interacts with impingement air to control and adjust the air against the moving web. Means are provided for adjusting and setting the profiler relative to cross machine drying air profiling.

Disclosed is a drying nozzle for realizing a high-efficiency drying device capable of drying an object to be processed to a sufficient degree. The drying nozzle includes a drying gas supply portion having an air supply tube for supplying air for drying a substrate whose surface is wet with a liquid by being sprayed against the surface of the substrate, and a gas/liquid mixture discharge portion which is spaced apart from the surface of the substrate by a predetermined distance to thereby make the thickness of the liquid adhering to the surface of the substrate prior to the drying constant and which has a porous material having a large number of through-holes for discharging the air/liquid mixture consisting of air and the liquid,from the surface of the substrate, the drying gas supply portion and the gas/liquid mixture discharge portion being arranged along the surface of the object so as to be adjacent to each other.
摘要:
A thermal equalizer for use in a paper web drying machine and process is disclosed. The equalizer is located at the junction of a crescent header and the associated nozzle box and its use results in a more uniform temperature and nozzle velocity in the cross-machine direction.
摘要:
Apparatus for drying substantially ellipsoid products, such as, for instance, eggs, which are conveyed over a conveying path by a conveyor. The apparatus includes a number of nozzles which are connected to a compressor. The nozzles are designed and arranged relative to the conveying path, such that the drying air blown out by these nozzles has a main flow direction which is both directed substantially perpendicularly to the surface of a passing product and blows directly onto at least the areas adjacent the points of a passing product.
