Retarder prover chambers

Hengel retarder proving chambers are designed for both bakers as well as the demanding industrial sector.
They are available for trolleys with grids or baking trays. They are dedicated to all types of production and any type of bread making with an aim to deliver the desired product in terms of hydration, texture or developed aromas. The interface Bi-Tronic Control 2 allows all types of fermentation: slow proving, traditional  retarder proving, linear proving, stepped proving and proving. Time, rise in temperature and humidity are perflecty mastered. Whatever the launch time of the cycle, the dough is always raised at the time of baking.

Technical description

Retarder provers are available as standard, for the following supports:

TROLLEYS WITH GRIDS: 660x810, 860x610, 960x810, 1070x810 or 1270x810 mm

ROLLEYS WITH BAKING TRAYS: 460x810, 660x810 or 810x910 mm

For any other trolley size, please do not hesitate to contact us.

  • Exterior surface in white lacquered steel, interior in stainless steel (included ceiling), thickness 6 cm (43kg/m3 polyurethan foam insulation)
  • Vertical door profile anodized aluminium resistant to shocks
  • Silicone gasket door easily removable and cleanable
  • Ergonomic interface Bi-Tronic Control 2
  • Automatic closing with a hydraulic actuator located outside trolleys ways
  • Interior profile protection made of stainless steel
  • R452A tropicalized remote refrigeration unit (remote installation possible within 10m connection) designed to operate up to 43°C room temperature 
  • Anti-short cycle for a longer compressor life
  • New sub-boiling reinforced hygrometry system (that is to say, the water can evaporate without reaching the boiling point).Electronic humidity sensor for better accuracy and reactivity. Adjustable sensor from 45 to 90% (accuracy of 1%).
  • Air mixing cycle during cooling to avoid temperature variations over the height of the trolleys
  • Reduced ventilation during the proving with possibility of adjustments to improve the proving results
  • Technical service duct fitted vertically for easy maintenance and cleaning
  • Evaporator with stainless steel frames and anti-corrosion treatment (cataphoresis)
  • Centrifugal fan for optimal heat exchange in the whole volume of the chamber
  • Heater with safety thermostat for heating during proving
  • Air service duct to ensure uniform flow
  • Power box fully protected IP65 can be positioned either on the chamber or on an outer wall (distance < 2 m from the control interface)
  • Interior lighting
  • Connection of the technical ducts with a connector. It makes impossible to make a mistake in the wiring and allows fault diagnosis with a test box.
  • As standard, hinges are on the right (left upon request)
