Description

TECHNICAL FIELD

[0001] The utility model belongs to the food processing technical field, concretely relates to a bean roasting machine for food processing. BACKGROUND

[0002] The drum-type roasting machine is a roasting equipment widely used in the field of food processing, mainly used for uniform heating and flavor stimulation of food materials such as nuts, coffee beans and cereals. Its core structure is a rotating drum with a spiral guide plate welded on the inner wall. The food materials are moved along the pushing direction of the spiral plate through the rotation of the drum, and heat conduction and stir-frying are realized by using the cylinder heating (gas, electric heating or hot air). Due to the high efficiency of continuous operation and the strong adaptability of capacity, such equipment is widely used in industrial roasting production lines, especially in coffee roasting and flavored nut processing, which needs to meet the strict quality requirements such as uniform heating of food materials and consistency of color. With the growing demand for high-end roasted products in the consumer market, the technical defects of the traditional spiral plate pushing mode are gradually exposed, which has become a key bottleneck restricting the improvement of processing quality.

[0003] The existing spiral plate design relies on continuous pushing in a single direction, which causes the food materials to flow in a single direction in the drum. The single-direction flow is prone to cause the food materials to accumulate and be unevenly heated, which may lead to different roasting degrees and inconsistent taste. SUMMARY

[0004] The technical problem to be solved by the utility model is that the existing spiral plate design relies on continuous pushing in a single direction, which causes the food materials to flow in a single direction in the drum. The single-direction flow is prone to cause the food materials to accumulate and be unevenly heated. In view of the shortcomings of the prior art, a bean roasting machine for food processing is provided.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme:

[0006] The utility model discloses a bean roasting machine for food processing, which comprises a machine body, a heating assembly arranged in the machine body, and a roasting assembly rotatably arranged in the heating assembly. The roasting assembly comprises a drum, a guide plate seat fixedly installed in the drum, and a switchable guide plate hingedly connected to the guide plate seat. The switchable guide plate is rotatably connected to the guide plate seat through a hinge and can be switched between a forward rotation folding position and a reverse rotation unfolding position. The forward rotation folding position limiting block is arranged on one side of the switchable guide plate parallel to the drum generatrix and is used for limiting the maximum angle of rotation of the switchable guide plate to the inside of the drum, so that the switchable guide plate is attached to the inner wall of the drum when rotating forward. The reverse rotation unfolding position limiting block is arranged on the side of the switchable guide plate intersecting the drum generatrix and is used for limiting the maximum angle of rotation of the switchable guide plate to the outside of the drum, so that the switchable guide plate is unfolded to a preset inclination angle when rotating reversely.

[0007] Further, the positive rotation folding position limiting block and the reverse rotation unfolding position limiting block are welded or bolted metal protrusions, the contact surfaces of which match the rotation track of the switchable guide plate, forming mechanical hard limiting.

[0008] Further, the hinge comprises a hinge shaft fixedly installed with the guide plate seat and a shaft sleeve fixedly connected with the switchable guide plate, the shaft sleeve being rotationally connected with the hinge shaft and slidingly connected with the hinge shaft along the hinge shaft axis direction;

[0009] The positive rotation folding position limiting block and the reverse rotation unfolding position limiting block are both provided in the shape of a circular truncated cone.

[0010] Further, the roasting assembly further comprises a spiral guide piece arranged at the feeding port, the spiral guide piece being used for guiding the beans inside the roller to be discharged from the roller when the roller is reversed.

[0011] Further, one side of the machine body is provided with a motor, the motor being used for driving the roller to rotate;

[0012] The inside of the machine body is provided with a bearing, and the roller is rotationally arranged in the inside of the machine body through the bearing.

[0013] Further, the heating assembly comprises a combustion chamber, the roller being rotationally arranged at the upper portion of the combustion chamber, the inside of the combustion chamber being provided with a gas stove head, the gas stove head being connected with a gas source, the gas stove head being used for igniting gas to generate a flame, and the top of the machine body being provided with a gas groove.

[0014] Further, one side of the machine body is provided with a cover plate, one side of the cover plate being provided with a feeding port.

[0015] Compared with the prior art, the present application has the following beneficial effects:

[0016] 1. Through the cooperative action of the positive rotation folding position limiting block and the reverse rotation unfolding position limiting block, the switchable guide plate forms two modes of folding pushing and unfolding turning when the roller is reversed; when the roller is rotated in the positive direction, the guide plate is attached to the roller to form free scattering, and when the roller is reversed, the guide plate is unfolded to a preset inclination angle to realize axial pushing, thereby forcibly changing the movement track of the beans, breaking the accumulation phenomenon caused by traditional one-way flow, significantly reducing local overheating or heat blind area, and realizing the synchronous optimization of the uniformity of bean heating and the consistency of color and luster;

[0017] 2. Through the linkage design of the mechanical limiting block and the switchable guide plate, the automatic switching of the guide plate working state can be realized without a complex control system, so that the same equipment can meet the uniform heating demand of the continuous roasting process and can be quickly switched to the discharging mode in combination with the spiral guide piece when reversed, and the processing efficiency and operation convenience are taken into account;

[0018] 3. The tilt angle of the guide plate in the reverse unfolding position, combined with the spiral guide plate, forms a forced discharge channel, avoiding the problem of bean residue or blockage, shortening the batch operation interval time, reducing the frequency of manual cleaning, and improving the stability of continuous production.
