An apparatus for roasting coffee beans comprises a roasting chamber for containing coffee beans. The roasting chamber is positioned within a resonant cavity of a waveguide. A microwave emitter produces microwave energy within the waveguide with one or more stable high intensity microwave regions within the roasting chamber to heat the coffee beans in the roasting chamber to a temperature sufficient to roast the coffee beans. A device configured to move the coffee beans within the one or more high intensity microwave regions is coupled to the roasting chamber.

A method, system, and apparatus for cooling a product comprises a chilling assembly further comprising a liquid flow assembly including a main conduit, at least one delivery conduit attached to the main conduit, and at least one nozzle attached to the delivery conduit wherein liquid is distributed onto a product from the at least one nozzle; and an airflow assembly including an air pump and at least one input conduit wherein the air pump drives airflow through the input conduit; a conveyor assembly conveys the product through the chilling assembly and a drain pan is configured below the conveyor assembly for collecting drainage and waste.

A reflectometer system for use with a non-contact actinic system includes a primary lens, and an illumination source and a detector positioned on an observation side of the primary lens opposite a goods production area and sample region. The illumination source emits an illumination beam through an illumination beam void between the primary lens and the housing, which is directed into the goods production area and sample region, and onto a flow or static sample of material to be tested. The material being tested then create a reflected beam, which shines back to the observation side of the primary lens through the primary lens to the detector. The general alignment of the illumination beam and the reflected beam create an extended sample region within the goods production area, as well as a compact reflectometer system structure.

A foodstuff preparation device may include a roasting chamber having grinding funnel configured for communicating a foodstuff, having a pre-ground particle size, between two or more grinding stones, such as a first grinding stone and a second grinding stone. A grinding motor may be configured to motivate the foodstuff between the two or more grinding stone so that the foodstuff exits from between a first grinding stone and second grinding stone with a first ground particle size, the first ground particle size smaller than the pre-ground particle size. Generally, the device may be configured to prepare foodstuffs, such as sesame seeds, by roasting and grinding them to produce Tahini, or any other similar prepared food. Optionally, the foodstuff may be communicated into the grinding funnel from a dispensing funnel or from a roasting cavity having a heating element configured to govern the temperature of the roasting cavity.

A coffee bean roaster includes a machine body, a roasting drum, a heating device and a fan module. The machine body includes a casing, a partition assembly, a receiving trough and a container. The partition assembly is disposed inside the casing and partitions the inside of the casing into a first chamber, a second chamber and a third chamber. The receiving trough is disposed outside casing and communicates with the first chamber, and the container is disposed in the receiving trough and has a plurality of mesh holes communicating with the receiving trough. The roasting drum is rotatably disposed inside the second chamber of the casing, wherein one side of the roasting drum has a plurality of through holes communicating with the third chamber. The heating device is disposed inside the second chamber for heating the roasting drum. The fan module is attached to the casing for pumping air to the outside of the casing through the first chamber and the third chamber.

The invention concerns a method to check a roasting system (10), said system comprising: a roasting apparatus (2), said apparatus producing smoke, anda smoke treating unit (3) configured to treat the flow of smoke produced by the roasting apparatus, and comprising a filtering device (221) and a couple of temperature sensors (24, 26) configured to measure temperatures of the flow of smoke upstream and downstream the filtering device (221), wherein, during a roasting operation, the method comprises the steps of:comparing the performances of the temperatures during at least a period of time of the roasting operation, andif the performances are similar along time, then displaying an alarm.

A coffee bean roasting-degree distribution measuring device includes a housing, a micro-processing unit, an image-capturing unit, a light-emitting unit, and a displaying unit. The housing has a first end and a second end opposite the first end with an accommodating space existing between the first end and the second end. The second end is disposed to surround a group of coffee beans under measurement. The micro-processing unit and the image-capturing unit are disposed inside the accommodating space and electrically connected to each other. The light-emitting unit is disposed inside the accommodating space and includes at least one light emitter and a circuit board electrically connected to the light emitter. The circuit board is further electrically connected to the micro-processing unit and each of the light emitter has a light emitting port facing toward the second end. The display unit is disposed on the first end and electrically connected to the micro-processing unit to display a measured roasting-degree distribution curve.

The present invention provides a method for controlling the roasting of coffee using microwave heating, the method being characterized in that roasting is completed in a coffee roasting device by: using raw coffee bean physical property data, pre-stored in a microcomputer or PLC, and coffee roasting operation information, input through an input unit, to calculate a roasting time (roasting retention time), an external air flow (hot air) temperature, and an appropriate microwave output corresponding to the temperature to achieve the target roasting step; and continuously operating a magnetron to input microwave energy. The continuous coffee roasting device using microwave heating comprises a microwave generation device intended to be used as a main heat source for roasting raw coffee beans and a microwave output control unit capable of controlling the microwave output of the microwave generation device, a hot air system providing an external air flow around the raw beans as hot air to prevent a cooling effect from occurring due to the external air when heating the raw beans with microwaves is installed, a transfer device continuously supplying the raw coffee beans and inducing the discharge of the coffee beans following roasting is provided, a shielding device for preventing microwaves from leaking out through open portions as the inlet and outlet portions of the roasting chamber (heating chamber and resonant cavity) must be open due to the raw coffee beans continuously entering and exiting the roasting chamber is installed, and a roasting device operation unit capable of controlling the overall operation of the continuous microwave roasting device is included.
