The invention discloses a wheel cleaning and blowing device, which is composed of four systems: a wheel positioning system, which completes initial positioning of a wheel on a roller bed and finds the position of a valve hole; a wheel advancing and dry-wet conversion system, in which the wheel advances while rotating, thus completing double-station dry-wet conversion of the wheel; a high-pressure water cleaning system, which is matched with the advancing rotating wheel to clean the wheel; and a compressed air blowing system, which is matched with the advancing rotating wheel to blow the wheel uniformly. The invention simultaneously discloses a wheel cleaning and blowing method. By adopting the device and the method, the wheel moves forward all the time during cleaning and blowing, the cycle is short, the efficiency is high, cleaning and blowing are integrated, and dry-wet separation is realized.

A freeze drying vessel having a drying chamber and moveable transfer belts each moved by a driven drum. Each transfer belt includes a transfer surface that transports frozen particles. Each transfer surface is arranged vertically in the chamber and moves in an opposite direction than a lower transfer surface. A removal device is located adjacent each driven drum that removes frozen particles from an end of each transfer surface, respectively, to enable removed frozen particles to flow downward to a lower transfer surface. A heating element is located adjacent each transfer belt to sublimate the frozen particles to form freeze dried product.

A hay bale dryer features a support frame inside of which there is delimited at least one bale space and at least one manifold carrying a set of aeration spears movable between a deployed position penetrating the bale space and a retracted position withdrawn therefrom. The manifold is moved between the positions by way of an actuator driven linkage, and the aeration spears comprise hollow elongated bodies of tapered thickness toward their distal ends for more effective penetration of the hay bales. A manufacturing method uses a hydraulic press to produce the hollow elongated bodies from lengths of originally cylindrically pipe. Horizontal feeding tables and upright feeding racks feature displaceable bale movers for moving queued hay bales along one or more queuing lanes into one or more bale dryers.

An exhaust quenching system is provided for use in connection with an asphalt concrete production plant having a dryer for drying aggregate material, an exhaust gas outlet conduit for discharge of exhaust gases from the dryer, and a dust collection assembly that is adapted to receive exhaust gases and entrained dust from the dryer via the exhaust gas outlet conduit. The exhaust quenching system is adapted to effect evaporative cooling of the exhaust gases in the exhaust gas outlet conduit upstream of the dust collection assembly.

A transport system, which is designed in particular for a dryer for drying workpieces, such as vehicle bodies, and which has a plurality of transport carts. The transport carts can be moved on a rail system in a transport direction. Workpieces can be transported by means of the transport carts. Each transport cart has a transport cart chassis. The transport cart has a fastening device, which is designed to establish a connection between the transport cart and a workpiece carrier in order to transport the workpiece carrier by means of the transport cart. The fastening device has thermal insulation, which impedes heat transfer between a workpiece carrier and the transport cart.
