Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of nut coating, and particularly relates to a continuous nut coating device and a coating method. BACKGROUND

[0002] Most of the nut products in China are still in the primary processing stage. The traditional processing technology for making coated seed and coated nut products is: selecting raw materials -> coating -> frying -> sprinkling seasoning powder.

[0003] In the coating process, a layer of sugar solution needs to be coated on the surface of the nut, and then a layer of powder is coated. The existing coating is usually completed by stirring with a coating machine. The coating machine is barrel-shaped. After one coating is completed, the coating machine needs to be stopped to discharge the coated nuts, and then the next coating can be performed. This not only reduces the processing efficiency, but also causes a layer of sugar solution and powder to adhere to the inside of the coating machine after long-term use, resulting in poor coating effect in the later stage, which needs to be cleaned regularly, also reducing the processing efficiency.

[0019] S2. After the kernels enter the feeding hopper, they move downward through the feeding channel. When the corresponding placement groove on the conveyor belt coincides with the feeding channel, the kernels enter the placement groove, and the kernels behind are stopped by the conveyor belt until the next placement groove coincides with the feeding channel. The kernels in the placement groove are driven by the conveyor belt to move to the discharge channel, so that the kernels slide into the discharge channel.

[0022] The beneficial effects of the present application are:

[0023] In use, the present application is fed by the feeder, coated with sugar through multiple groups of sugar liquid waterfall, and then conveyed by the vibrating conveyor. At the same time, the powder falls down to cooperate with the continuous jumping movement of the kernel to achieve the effect of powder coating. Finally, it is discharged. This series of coating process improves the overall processing efficiency.

[0024] In the present application, two partitions are provided, and a layer of powder is laid between the two partitions. In this way, when the kernel coated with sugar liquid falls on it, it will be coated with a layer of powder. The kernel in the vibrating conveying process is not easy to stick to the vibrating plate when it contacts the vibrating plate, so as to ensure that the surface of the vibrating plate is not easy to produce adhesion, and ensure that the kernel is normally conveyed outward.
