THE JAVAPRO-CRC ULTRA
Five different capacities available: 1, 2, 5, 10, and 20 lb. This coffee roaster is a proprietary design of CoffeeRoastersClub. Note that roaster shown in pictures is the 10 lb. Version. 1 lb., 2 lb., & 5 lb. versions are smaller but same overall look. 20 lb. version has a permanently affixed drum and a dump door on side of roaster.
All roasters have a shell composed of 18 gauge food quality stainless steel with the exception being the 20 lb. capacity model which is 16 gauge throughout. The back and sides of all versions are covered in ceramic insulation (for superior heat retention) and held in place with a special outer aluminum cover. All stainless front door has a glass viewing port. Drum is nicely backlit during roasting operation so you can see the beans tumble in the drum while roasting.
Coffee roaster drum is 100% Stainless Steel, welded construction. Drum perforations are 5/32" diameter. Drum has Internal mixing vanes. Drum rotates at 60 RPM which is considered optimal RPM. All roaster drums, with the exclusion of the 20 lb. roaster, are removed from interior of roaster to fill with beans, placed back in roaster to roast, then again removed after roasting to dump beans. The 20 lb. version is filled through an upper port on the outer top of the roaster.
Roaster has two banks of high efficiency Rapid-Response ceramic infrared heating elements. One bank is located on the upper back wall of the roaster and one on the lower back wall of the roaster. 1 lb. capacity draws 1,000 watts, 2 lb. capacity draws 1,500 watts, 5 lb. capacity draws 2,000 watts,10 lb. capacity draws 3,000 watts, 20 lb. capacity draws 6,000 watts. All versions operate on 110VAC, with the exclusion of the 20 lb. version which operates on 220VAC.
A chaff collection pan sits on bottom floor of roaster.
PID Option (Available on 1, 2, 5, and 10 lb. versions. PID comes standard on the 20 lb. version.) The PID uses a thermocouple probe which inserts through the side of the roaster right into the drum to read bean mass temperature. The PID provides electronic temperature control to automatically adjust roasting temperature. This allows precise temperature adjustments for complex roast profiles.
Non-PID Versions also available for 1, 2, 5, and 10 lb. versions. These versions use 2 manual switches in place of a PID to control heating elements. An analog long-stem thermometer is used in place of thermocouple probe. Temperature is controlled by manually turning switches on or off.
1 lb. & 2 lb. version uses typical 15 amp 3 prong plug. 5 lb. version uses 20 amp plug. 10 lb. version uses 30 amp plug. The 20 lb. roaster has a 4 prong 250 volt cord. You will need the applicable electrical outlet for each coffee roaster.
Roasting Times & Method Applicable To All javaPRO-CRC ULTRA's
To summarize: Take out drum and fill with coffee beans. Reinsert drum. Insert temperature probe into bean mass. Turn on motor & heating elements. Turn on exhaust fan when necessary. Roast to desired roast level then turn off motor and heating elements. Remove drum with heat proof gloves and dump beans into a cooling utensil. Dechaff beans with a Bean Cooler/Dechaffer. Typical roasting times are 20 - 25 minutes for a full load to City+. Less beans than rated capacity being roasted will decrease the amount of time to achieve desired roast. You may preheat roaster to get 5% to 10% reduction in roasting time.
Ventilation Applicable To All javaPRO-CRC ULTRA's
All roasters have a ventilation system for smoke extraction which vents roasting smoke to the outside. This system is attached to side of roaster. A 4 foot length of 4" diameter expandable aluminum ventilation tubing (6" diameter on the 10 lb. and 20 lb. versions) is included for use with the ventilation system. This tubing is intended for temporary use. We recommend solid wall tubing for permanent installation.
Air Control Availability
Variable Speed Exhaust ventilation system for controlling air flow is available as an option at extra cost on the 10 lb. Capacity Standard, 10 lb. Capacity PID, and 20 lb. roasters. No other capacity is applicable for this function.
All models are stainless steel without exception.
Complete operating and roasting instructions included with all models.

Note that roasting capacity indicated is raw unroasted bean weight.
OTHER IMPORTANT INFORMATION: Check with local zoning and fire department for necessary permits, smoke ductwork needed, etc. prior to purchase. Obey all safety precautions. Never leave coffee roaster unattended while roasting. Heat proof gloves should be worn when using roaster. Extension cords should not be used with roaster (or any electric coffee roaster for that matter) as they typically lower voltage.
