4 4 Description of function Description of function This chapter explains the basic working principle of the Mini Spray Dryer B-290 Basic (open mode only) and the Mini Spray Dryer B-290 Advanced (for closed mode operation). It also shows how the instruments are structured and provides a general functional description of the assemblies. 4.1 Functional principle of the drying gas The Mini Spray Dryer B-290 operates according to a co-current drying gas (e.g. air in open mode) and product stream.
4 Description of function The nozzle cap has an inserted ruby stone with a precise opening and sharp edges to guarantee a precise and reproducible spray cone. The smaller nozzle cap of 1.4 mm diameter leads to a lower consumption of spray gas, as the concentric ring around the nozzle is smaller. This nozzle is recommended when nitrogen is used to minimize operating costs. The larger nozzle cap opening of 1.

4 4.6 Description of function Spray chilling accessory During spray chilling a hot melt is dispersed into a cold gas stream. The droplets are solidified into particles and are separated. The matrix substance and the active ingredients are heated above the melting point. Highest melting point is 70 °C. The nozzle is also heated to prevent any blocking. No additional thermostat is required, as the existing heating control and peristaltic pump in the instrument are used.
4 4.7.1 Description of function Feed switch valve and remote control panel Fig. 4.7: Feed switch valve and remote control panel The remote control panel enables an easy operation even within a closed fume hood. The flow meter for the spraying gas is the only parameter which cannot be adjusted via the remote control panel. The feed switch valve is a useful tool together with the remote control panel.

5 Putting into operation The Inert Loop B-295 has a sideward hose connection for the exhaust gas. Due to the constant feeding with nitrogen, a certain amount of it is permanently leaving the system through this outlet tube. If air is sucked in through the tube, this is an indication that the closed loop is not tight.

6 6.2 Conversion tables for the parameters 6.2.1 Flow meter spraying air (rotameter) Operation The rotameter is an indicator for the spray gas flow. The table gives a correlation between indicated height and volume throughput. The nozzle has a certain pressure drop which increases with higher gas flow. As the gas volume strongly corresponds to the actual pressure, the table also contains a row for the effective volume flow, determined in a spray process with air.
6 6.2.3 Operation Aspirator The aspirator has a maximum gas flow rate of approx. 35 m3/h. The flow depends on the pressure drop of the overall system. To determine the exact volume flow for steady and reproducible operating conditions, a measurement tube is supplied as an accessory. A handheld gas flow meter (hot-wire flow meter) is required for the measurement. Fig. 6.4: Aspirator settings versus throughput 6.3 Spray process During the spray process some parts i.e.
6 6.4 Operation Optimizing parameters The parameters relevant for the spray process (aspirator and pump performance as well as inlet temperature) all correlate with and depend on each other. To give you an overview over the parameter settings best suited for your process, special training papers can be downloaded directly from the Internet. Please visit our homepage www.buchi.com. In the section Fields of Activities/Spray Drying, you will find the document to download. 6.
6 Operation If the system is run with a PTFE filter, the fine particles can partially be recovered by counter-pulsating the filter membrane and blowing the particles away. For this purpose, proceed as follows: Fig. 6.5: Recovering particles of the outlet filter • A ttach the PTFE membrane instead of the polyester filter and close the bottom with a polypropylene plug. • Separate the manometer tube from the filter and remove the filter housing completely from the holder.
6 6.7 Operation Operation with the Inert Loop B-295 ! Danger Death or serious poisoning by gases or particles due to O2– sensor or filter malfunction • • • • • Exchange defective O2– sensor immediately Exchange O2– sensor regularly within the specified maintenance intervals Exchange clogged filters immediately Exchange filters regularly within the specified maintenance intervals Dispose of filter immediately ! Danger Death by suffocation or serious poisoning by inhalation of inert gases.
6 2. 3. 4. 5. 6. 7. 8. 6.7.1 Operation Usually the Inert Loop is set on -20°C for optimal solvent recovery. Some solvents tend to freeze in the Inert Loop B-295, while working with those please adjust the set temperature to a higher one, use the buttons c and d. The display of the Inert Loop B-295 e shows the set temperature and the current temperature. Switch on the aspirator (see figure 6.2 on page 52). Check whether the spray gas source is an inert gas, normally nitrogen.
6 6.8 Operation Operation with the Spray Chilling Accessory To operate the Spray Chilling Accessory, proceed as follows: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 55 Fill a heating liquid, e.g. water or a thermal oil (polyethylene glycol PEG 400 with low viscosity) into the heating bath and check whether the tubings are connected correctly. For sample melting points below 50 °C, water can be used as heating liquid.
6 6.9 Operation Mini Spray Dryer B-290 acid resistant For basic operations please see chapters 6.1–6.7. Nozzle cleaning instructions 1. Clean the nozzle parts immediately after each spray drying run. 2. Wash the nozzle parts with a mild detergent solution. 3. Rinse the parts with hot water and let them dry. 4. Examine the nozzle parts under a microscope to verify that they are clean. 5. Check the integrity of the O-rings. Replace if necessary.
7 7 Maintenance and repairs Maintenance and repairs This chapter gives instructions on all maintenance work to be performed in order to keep the instrument in good working condition. ! Danger Death or serious poisoning by inhalation or incorporation of dried particles during maintenance.
7 ! Maintenance and repairs CAUTION Minor or moderate injuries by hot heating bath content. • • Do not drop any water into the hot heating liquid Wear safety goggles Notice Risk of instrument and instrument damage by liquids and detergents. • • • 7.1 Do not spill liquids over the instrument or parts of it Wipe off any liquids instantly Use ethanol or soapy water as detergent only Housing Check the housing for defects (switches, plugs) and clean it regularly with a damp cloth. 7.
7 7.4 Maintenance and repairs Aspirator cleaning The aspirator of the Mini Spray Dryers can be contaminated from particles, especially when no outlet filter is used. This is a description how to clean the aspirator efficiently and fast. Disconnect the “Polypress” tube from the glass assembly and heater respectively. Fig. 7.1: Disconnecting Polypress tube • Fill one vessel with water and prepare an empty canister with a small opening.
7 • • • • 7.6 Maintenance and repairs Provide a collection vessel to collect the cleaning medium flowing from the system. Open the drain valve and lower the exhaust tube, so that the cleaning medium flows out. Rinse out and dry the condensate vessel. Reinstall the condensate vessel. To dry the working circuit connect the Mini Spray Dryer B-290 and dry it by running the Aspirator with dry air.
7 7.8 Maintenance and repairs Replacing the oxygen sensor of the Inert Loop B-295 After approximately 2 years of operation the oxygen concentration displayed by the sensor decreases drastically. The sensor should now be replaced. For this purpose: • • • • • Open the front plate with an allen key. Disconnect the cable by turning the plug. Screw the sensor out and replace it by a new one. Reconnect the cable. Calibrate the sensor according to chapter 7.6, Calibrating the oxygen sensor. Fig. 7.
