5.2 Function The roaster PROBATONE Typ 2 serves for batch-wise roasting and cooling of foodstuffs. Two technical variants are available: Variant 1: Roasting and cooling exhaust air combined (ill. 2) Variant 2: Roasting and cooling exhaust air separated The raw product has to be filled into the filling bin (B1) in batches. A filling slide (B2) forms the lower terminating section of the feed hopper. Arranged below the roasting drum (R1) is a gas burner (D1) that releases the heat. The temperature in the drum is measured permanently and displayed on the digital temperature display on the operating panel. When the requested filling temperature is achieved, the raw product previously poured into the feed hopper is passed to the roasting drum by raising the filling slide. After the filling, the slide gate has to be closed again. The roasting drum is a horizontally arranged cylinder with rotary drive. Ledges are arranged in circuits in the roasting drum. These ledges are inclined to the axis and intensively revolve and mix the product in order to guarantee a uniform heat transfer. The roaster fan (V6) sucks off the resulting roast exhaust gases. It conveys to the roasting cyclone (F1), by which chaff and dust are separated out of the roasting air by means of centrifugal force. A chaff collecting bin (F12) fixed under the roasting cyclone collects the chaff. The mechanically cleaned air escapes into the open via a chimney (Y1). The progress of roasting can be monitored by a sight glass resp. with the help of the sampler.

Now the roasted product flows onto the cooling sieve and is distributed evenly there. After the emptying, the emptying flap is closed again. The stirring arms of the cooler move the product in regular layers over the horizontal sieve bottom. Under the sieve bottom there is a sweeping device to clean the cooler bottom. The roaster fan (V6) sucks air through the product and the sieve bottom. The product thereby gives heat to the air.

Sweeping device

The cooling air escapes via a chimney (Y1) into the open. During the cooling of a batch, a subsequent batch can be roasted in parallel if the filling temperature had been reached before. After the cooling the product is emptied in a provided bin by means of the emptying flap (B4)

5.2.2 Roasting and cooling exhaust air separated Concerning variant 2, the stirring mechanism in the cooler (R2) and the cooler fan (V10) on the operating panel is switched on when the requested colour degree is reached. For emptying the roasting drum, the emptying flap (B3) must be opened. Now the roasted product flows onto the cooling sieve and is distributed evenly there. After the emptying, the emptying flap is closed again. The stirring arms of the cooler move the product in regular layers over the horizontal sieve bottom.

6.1.6 General remarks concerning exhaust pipe lines  The exhaust air pipe line should be as short as possible and slightly ascending. Sharp redirections and neckings have to be avoided.  Exhaust air pipe lines after the roasting cyclone and cooler fan  which are longer than 15 m,  that have a 1 m horizontal part and/or  have more than 2 x 90° bends, need possibly an additional fan.  Easy accessible cleaning openings are recommended.  The application of folded spiral-seam pipes as exhaust air ducting is not recommended since the pressure loss in these pipes is higher in comparison with smooth pipes. Apart from that the contamination trend is stronger and thus the risk of fire. 3

 The roaster emits an exhaust gas volume flow of up to 420m /h. Sufficient ventilation of the installation room has to be secured.  Pipe lines and chimney have to be regularly (monthly) examined with regard to deposits.  The emanation of the roast exhaust air into the open should be vertically above the roof.  Wall and roof hoes must be insulated in a fire-resistant way against the exhaust air pipe line.  The relevant regulations for the erection of chimneys / exhaust gas units and the local regulations have to be adhered to.  In case of doubt please contact the responsible chimney sweeper and a specialist firm.  The operator is responsible for the duly execution of the connecting lines.

6.2.1 Drum gap Action step The factory adjustment of the drum gap is 0.5 mm (cold status). Before the first commissioning the gap has to be checked by means of the delivered feeler gauges. For this purpose the emptying flap has to be opened. Afterwards, check the gap with the feeler gauge through the open emptying flap.

6

The gap width between the roasting drum and the housing is adjustable by turning the front drum bearing.  Loosen the 3 bolts (6) with hexagonal recess on the front bearing with a hex head wrench.  Put on hook spanner and turn bearing housing.  For extension of gap – turn clockwise.  For reduction of gap – turn counter-clockwise  After the adjustment retighten the 3 hexagonal recess bolts.

6.2.2 Slide gate roasting exhaust air Action step The air quantity regulation in the roaster is done with a slide gate in the roasting exhaust air duct. Slide gate adjustment

The deeper the slide gate plate is adjusted in the exhaust air duct, the lower is the negative pressure in the roaster. The slide gate is half opened (factory setting). It must be adjusted individually depending on the chimney connection.

Installation position: Direction of the exhaust air flow Ill. 14: Slide gate in the roasting exhaust air duct



Slide gate opened too far: Beans are sucked.



Slide closed too far: The burner switches off

Please consider the correct installation position in order to avoid that chaff accumulates on the slide gate.

ATTENTION! Risk of burns by hot surface! Do not move the slide gate during the roasting process. Burnings on the hands might be the consequence. Therefore: – Only adjust the slide gate when the machine is cold.

HINT! If the negative pressure is too high, beans might be sucked. If the negative pressure is too low, the burner switches off

Installation and initial operation Action step

REMARK! If you have a manometer available (e.g. Extech HD 350), you should adjust the optimal negative drum pressure of -2.1 mbar!

For this purpose:  Dismount the rear sheet metal cladding on the roaster top part.  Untwist the valve screw on the measuring nipple.  Install the hose of the measuring unit.  Switch on the roaster fan on the operating panel.  You can now start your measurement and read the pressure on the measuring unit.

 Adjust the pressure with the help of the slide gate as described above.  If you have achieved the correct negative pressure, deactivate the roaster fan again.  Pull of the hose from the measuring nipple and turn in the screw again.  Close the rear flap of the roaster again.

6.2.3 Pressure monitor A pressure monitor (see arrow) serves for the burner switch-off in case the roast exhaust air ducting is closed or there is a defect of the roaster fan drive. Action step Prior to the initial operation and after a corresponding repair the pressure monitor can be readjusted as follows:  Dismount rear sheet metal lining on the roaster top.  Remove synthetic material cover of the pressure monitor.  Switch on the roaster fan on the operating panel.  Based on the max. scale value the adjusting knob has to be slowly turned clockwise until the switching contact closes and the release for the burner is given. Ill. 15 Pressure monitor

HINT! In the factory the pressure monitor is adjusted to a pressure of approx. 0.7 mbar negative pressure.  After adjustment reattach the synthetic material cover.  Mount the rear sheet metal lining on the roaster top.
