HW-300 coffee roaster machine

External

• Using OMRON thermostat.Display temperature is more sensitive and accurate.
• Equiped with an OMRON timer, easy to check the baking time.
• Electronic throttle control, through the knob to change the exhausting motor speed and the fan speed, to realize stepless control.
• LED colorful stainless steel switch button,service life of up to 50000 times.Not only beautiful and more easy to operate.
• Large flame observation window, so that the baking room situation is absolutely clear.
• The sampling handle using the finest rosewood, with artificial mechanical design, make your grip more comfortable.

• Coffee bean feeding device adopt 304 stainless steel materials,can ensure food safety. Just gently stir, coffee beans can quickly fall into the drum.
• Equiped with abservation window.You can abserve the coffee beans at any time when you are baking beans.
• The cooling plate can be removed from the machine, it is convenient to pour the coffee beans.
• Independent cooling device,can make the roasted coffee beans quickly cooling.

• Drum motor speed is adjustable,the range is 0~100 rpm.
• The machine is installed with USB interface, can communicate with the computer. Artisan software can be perfectly compatible. The machine shell has three colors:golden,titanium and sliver for you choose.
• Gas pressure control:Gas pressure meter is equipped with 304 stainless steel needle valve,can achieve more accurate gas pressure adjustment.
• Automatic ignition function:The ignitor will be automatically fire up when you press the ignition button.Then the solenoid valve will open automatically and switch on the gas.The red LED button will lit up if the burner are flaming.Solenoid valve will shut off gas automatically and the buzzer will start to ring if there is no flame in 10 seconds.
• Detection of flame extinction:The ignitor will be automatically fire up if the flame goes out whenyou are baking.Solenoid valve will shut off gas automatically and the buzzer will start to ring if there is no flame in 10 seconds.
• Thermostatical control:Temperature controller can set the constant temperature.The machine will shut off the gas when the temperature reaches the set temperature.When the temperature is lower than the set temperature,the machine can switch on the gas automatically and start heating,so that the temperature has been constant at the set temperature.

Inside

• Baking drum:Using the international standard food grade stainless steel, to make sure the pure taste of roasted coffee beans is not affected by other off-flavors. With the independent design of the stirring blades,the coffee beans will do reciprocating moving in drum, make the baking more uniform, the skin more easily to drop off.
• Burner: using high efficiency energy--saving furnace head,the fire is more powerful,and more economical to use. Maximum heating rate is 20 degrees / min, to meet the changing needs of the baking.
• Insulation layer: There is a 30mm thick insulation layer to reduce temperature loss.

Operation

I. Connection of gas and electric circuit

1. Connect one end of the gas pipe with a pressure reducing valve to the gas source, the other end connected to the gas machine interface, and fixed with a clamping band to prevent gas leakage.

2. Connect the machine power plug to the single phase AC 220V power supply.

3. Power button: press the power button, the drum motor and the hot air blower start running.

4. Heating button: press the heating button, the machine will automatically switch on gas and ignition.Need to confirm the gas control valve open in a smaller position before pressing the heating button,Otherwise,the gas pressure meter will be damaged if the gas flow is too large.The maximum pressure is limited below 5KPa.

5. Cooling button: press the cooling button,the cooling fan start working.

Cleaning and maintenance

• There will be some silver skin fall into the drawer during the baking process , just pull out the drawer and pour out the silver skin.
• There will be a little silver skin and broken beans under cooling plate, just take out the cooling plate to clean the inside.
