DEVICE FOR ROASTING BEANS

A device for roasting beans which is significantly easier to install and place in a bean-roasting machine includes a chassis, a bean roasting tube, and a driving member. The chassis defines an accommodating cavity and a receiving hole communicating with the accommodating cavity. The bean roasting tube includes a rotating member and a chamber. The rotating member is detachably connected to the chassis. The chamber includes a first end plate, a second end plate opposite to the first end plate, and a bearing piece fixedly connected between the first end plate and the second end plate. The second end plate faces the receiving hole and is rotatably connected to the rotating member. The driving member is fixed to the first end plate and movable to drive the chamber to rotate in the accommodating cavity.

FIELD

The subject matter herein generally relates to a device for roasting beans.

BACKGROUND

Bean roasting devices include cases and bean roasting tubes disposed in the cases. The case includes a door and two walls arranged on both sides of the box door. The two walls have fixing pins and fixing holes for fixing two opposite ends of the bean roasting tube. When the door is opened to install the bean roasting tube, the bean roasting tube is first placed horizontally in the chassis, and then tilted so that one end of the bean roasting tube is connected to one of the two walls, and the other end of the bean roasting tube is adjusted to connect with the other one of the two walls. During the above described installation process, the bean roasting tube crosses between the two side walls. Due to the blocking of the bean roasting tube, it is difficult to determine the position of the fixing pin and the fixing hole, thus installing the bean roasting tubes in the case is unnecessarily time-consuming.

Referring toFIGS. 1-5, the present application provides a device100for roasting beans. The device100includes a chassis20, a bean roasting tube40, a driving member70, a heating member (not shown), and a housing80. The chassis20defines an accommodating cavity21. The bean roasting tube40is fixed to rotate in the accommodating cavity21, and turns over the beans within the bean roasting tube40. The driving member70is connected to the bean roasting tube40for driving the bean roasting tube40to rotate in the accommodating cavity21. The heating member is fixed in the accommodating cavity21to dry and roast the beans in the bean roasting tube40when the bean roasting tube40rotates in the chassis20. The housing80surrounds to define a receiving cavity (not shown), and an opening (not shown) on one side communicating with the accommodating cavity21. The receiving cavity is configured to accommodate the chassis20, the bean roasting tube40, the driving member70, and the heating member. The opening is opened to allow placement of the bean roasting tube40, and the opening is closed to dry the beans in the bean roasting tube40. In an embodiment, a rotating door82is installed at the opening. When the rotating door82rotates away from the chassis20, the opening is opened, and when the rotating door82rotates to the chassis20, the opening is closed.

The chassis20includes a front panel22, a rear panel23, and a side panel25connected between the front panel22and the rear panel23. The front panel22, the rear panel23, and the side panel25surround and define the accommodating cavity21. The front panel22defines a receiving hole26communicating with the accommodating cavity21and the opening. The front panel22is provided with a fixing portion27at the receiving hole26to connect with the bean roasting tube40. In an embodiment, the fixing portion27is a slot. The rear panel23defines a through hole231.

The driving member70is disposed outside the chassis20. The driving member70includes a rotatable driving portion71. One end of the rotatable driving portion71passes through the through hole231to be received in the accommodating cavity21and connect to the bean roasting tube40. The rotatable driving portion71rotates the bean roasting tube40. In an embodiment, the driving member70is a motor, and the rotatable driving portion71is a driving shaft.

The bean roasting tube40includes a chamber50and a rotating member60. The chamber50includes a first end plate51, a second end plate52opposite to the first end plate51, and a bearing piece53fixedly connected between the first end plate51and the second end plate52. The first end plate51defines a fixing hole511. The fixing hole511is configured to fix the rotatable driving portion71to fix the chamber50to the driving member70. The second end plate52faces the receiving hole26and defines a rotating hole521. The rotating hole521is configured to connect with the rotating member60so that the chamber50rotates with the rotatable driving portion71. In an embodiment, the fixing hole511is a rectangular hole, and the driving shaft is a rectangular shaft matching with the rectangular hole. The first end plate51and the second end plate52are disk-shaped, and the bearing piece53is cylindrical. In another embodiment, the first end plate51and the second end plate52can be square in shape, and the bearing piece53can be a tetrahedron. It can be understood that the first end plate51, the second end plate52, and the bearing piece53can be other shapes, as long as they will carry and contain beans. The bearing piece53includes a curved first carrying piece531and a curved second carrying piece532. The first carrying piece531defines a notch533. The second carrying piece532is disposed at the notch533to open and close the notch533. When the notch533is opened, the beans can be placed in the chamber50. When the beans are placed in the chamber50, the second carrying piece532closes the notch533and is fixed to the first carrying piece531.

The rotating member60is rotatably connected to the second end plate52and detachably connected to the fixing portion27. After the rotating member60is fixedly connected to the fixing portion27, the bean roasting tube40is rotatable relative to the rotating member60. In an embodiment, the rotating member60includes a connecting member61, a positioning member62, and a fixing member63. The connecting member61is disposed on a side of the second end plate52away from the first end plate51. The connecting member61defines a through hole611and has a connecting portion612at an edge of the connecting member61. The connecting portion612is detachably connected to the fixing portion27. In an embodiment, the connecting portion612is a buckle, and the buckle is detachably locked in a slot on the front panel22to connect the connecting member61to the front panel22. The positioning member62includes a rotating shaft621and a blocking portion622fixed to one end of the rotating shaft621. An end of the rotating shaft621away from the blocking portion622passes through the through hole611and the rotating hole521and is positioned on a side of the second end plate52close to the first end plate51. The blocking portion622is positioned on a side of the connecting member61away from the second end plate52. The fixing member63is positioned on the side of the second end plate52close to the first end plate51, and fixed to the rotating shaft621to rotatably connect the chamber50to the rotating member60. Because the chamber50is rotatably connected to the rotating member60, when the driving member70rotates the rotatable driving portion71, the chamber50can rotate in the accommodating cavity21, thereby drying and roasting the beans positioned in the chamber50.

The rotating member60further includes a first lubricating member64and a second lubricating member65, which reduce vibration and noise when the bean roasting tube40rotates. The first lubricating member64and the second lubricating member65are made of TEFLON. The first lubricating member64is sleeved on the rotating shaft621and positioned between the blocking portion622and the connecting member61. The second lubricating member65is sleeved on the rotating shaft621and positioned between the connecting member61and the second end plate52. In an embodiment, the rotating member60further includes a sleeve66. The sleeve66is positioned between the second lubricating member65and the second end plate52, and sleeved on the rotating shaft621, so that the chamber50rotates in a stable manner around the rotating shaft621.

When installing the bean roasting tube40in the chassis20, the opening is opened, the first end plate51faces the opening, and passes through the opening and the receiving hole26to be fixed to the driving member70. At this time, the second end plate52faces the receiving hole26, and then the rotating member60is rotated to connect the rotating member60to the chassis20. Thereby the bean roasting tube40is installed in the chassis20. Then the opening is closed, the beans in the bean roasting tube40can be roasted by the device100. A conventional bean roasting tube cross-positioned in the chassis is installed much less conveniently, and over a longer time.
