The Revent PR204-180 PROOFER/RETARDER Roll-In Retarder/Proofer
The Revent PR204-180 is the largest roll-in proofer/retarder in the Artisan range, holding eight end load single racks or four doubles behind a 62.1 in. wide opening. Central bakeries and commissaries use a cabinet this size to keep a whole night of production under one set point, which removes the guesswork that comes with running two chambers on slightly different curves. Every temperature from 27 to 113 °F is available under PID control of temperature and humidity, so eight racks of shaped dough can retard until the small hours and then follow a programmed curve to full proof. Thawing frozen dough is part of the same repertoire, but frozen holding for days sits outside the printed range. Because the cabinet arrives knocked down and passes a 36 in. minimum intake opening, it can be walked into a room a finished unit would never enter, then set on a leveled floor with three phase power at 24 A, cold water, and a 1 1/2 in. NPT drain.
Retarding, Slow Proofing, and Thawing in One Chamber
Retarding, slow proofing, and thawing run in the same chamber, which at eight racks means an entire production schedule lives behind one set of doors. Shaped product loaded at the end of a second shift holds cold until the curve starts, then arrives at proof temperature as the ovens come up. Handling that volume with a cold room plus a proof box means eight rack moves in the early morning, each one a chance for your crew to catch a tray or dry out a surface.
PID-Regulated Temperature and Humidity
Both temperature and humidity are programmed and displayed on a touch screen panel, and optimized PID regulation keeps them from cycling, which matters more as chamber volume grows and every overshoot costs energy to correct. A computer controlled fan with 200 speed steps moves the air, slow and quiet for a long retard, faster when eight racks have to reach proof together. Humidity can be added during cold storage, so the last rack loaded does not skin while the first is still coming down to temperature.
Electromagnetic Steam Generator
Moisture comes from an electromagnetic steam generator whose steam container has no mechanical or electrical parts, so nothing inside it wears out on a duty cycle this heavy. Steam enters the chamber through an internal nozzle placed after the fan and the temperature elements, arriving as part of the airstream rather than as a wet plume. Direct cold water systems send incoming water into the chamber and this one does not, which closes off a common route for waterborne bacteria, and the generator drains automatically.
Roll-In Capacity for Eight Singles or Four Doubles
Eight end load single racks at 18 by 28.5 in. fill the chamber in two columns of four, or four double racks at 36 by 28.5 in. take the same space, all through a 62.1 by 76.6 in. door opening. Exterior width is 70.8 in. and depth is 80.2 in., with 10 in. of rear projection for the refrigeration package and a 6 in. base clearance. Overall height is 100 in. while the cabinet body itself stands 76.6 in., so the clearance worth checking is the ceiling in the finished location.
Stainless Steel Cabinet with Integrated Refrigeration
Interior and exterior surfaces are stainless steel, the doors carry double pane glass, and LED lighting keeps the far end of an eight rack load visible from the aisle. Refrigeration is integrated on the cabinet and runs R449 refrigerant for compliance with current air quality rules, so your installer has no remote condensing unit to place and no line set to run. Level the floor, allow at least 2 in. to any wall, and leave the front and the top open for service and ventilation. An insulated and heated floor is available as an option.
