Bench Top Mini-Coater Dryer

• Easily fits on your benchtop.
• Coats tablets and spheroids.
• Convenient batch size from 1 to 130 tablets.
• Easily coat up to 60 grams of spheroids or pellets.
• Dry up to 100 grams of spheroids or pellets.
• Ideal for coating small amounts of material.
• Ideal for coating small amounts of material when products are costly or in limited supply
• Small numbers of repeatable samples can be made for trial work
• Excellent quality of applied coating
• Small quantities of tablets can be produced quickly for testing of experimental coating materials and or the development of a few coated tables for experimental use.
• Potentially expensive or scarce tablet or spheroid materials are not wasted.
• Better quality coating than with a pan coater

Production Capacity:

Coating Tablets:

Coat from 1-130 tablets

Coating Spheroids:

Coat from a few grams to about 60g of spheroids/pellets

Drying Spheroids:

Dry pellet/spheroid batch sizes up to 100g

Processing Time:

Spraying/drying a sample of tablets or spheroids normally takes about 10-15 minutes, depending on coating materials and the thickness of the required coating.

Product Size:

• Pellets: Down to 200 microns
• Tablets: Up to 10mm diameter

Standard Design Configuration:

Size: approximately 50 x 55 x 60 cm.
Weight: approximately 32kg.
Material: Cabinet is grained 304 stainless steel.
Contact parts in 316 stainless steel, PTFE and polypropylene.
All machine pipework in stainless steel and acetal.
Coating solution flow controlled by a Watson Marlow Peristaltic Pump.

Utilities:

Electrical supply single phase. Voltage according to customer requirements. Compressed air with a flow rate of 60l/min at 2.5 bar required.

Operation and Controls:

Custom designed microcontroller based system
Monochrome LCD graphic display
Mechanical agitation control variable from 10 to 25 Hz.
Airflow control variable up to 60CFM at source
Peristaltic pump variable from 5 to 50ml per hour (dependant on delivery pipe diameter)
Air temperature variable from ambient up to 700C with feed back loop control.
Count up timer with start/stop and reset controls.
A "wake –up” condition. The last used experiment parameters will be stored and when the machine is switched on all parameters will start set at their last used condition.

Operational parameters:

Air flow, temperature and vibration frequency are user controlled.

Consumable Items:

Polypropylene mesh discs
Silicon tubing (0.8mm bore or 1.6mm bore)
