Therefore, in order to solve the above problems, it is necessary to establish a stevia coating drying system. Utility Model Content

[0003] The first technical problem to be solved by the utility model is: in view of the deficiencies of the prior art, a stevia coating drying system is provided, by which the product coating is made more uniform, thereby improving the quality of the product.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0010] After adopting the above technical solution, the beneficial effects of the utility model are:

[0011] The stevia coating and drying system includes a cyclone separator connected to the discharge port of the coating machine, the discharge port of the cyclone separator is connected to the feed port of the drying device, the interior of the drying device is provided with a first airflow distribution component and a second airflow distribution component, the air inlet of the drying device is connected to the hot air supply device, the discharge port of the drying device is connected to the vacuum feeder, the discharge port of the vacuum feeder is connected to the silo, and a weighing module is provided outside the drying device, and the weighing module and the hot air supply device are respectively electrically connected to the controller. In actual production, the stevia coated material is drawn into the interior of the cyclone separator, and then the coated material falls into the interior of the drying device. When the weighing module detects that the appropriate weight has been reached, the controller starts the hot air supply device to operate, and the hot air enters the interior of the drying device from the air inlet, is evenly dispersed by the first airflow distribution component and the second airflow distribution component, and then the coated material is dried. After drying, the coated product enters the silo through the vacuum feeder. The coating drying system of the above structure is reasonably designed, so that the coating material is evenly heated, the uniformity of the coating is ensured, and the quality of the product is improved.

[0012] Since the first airflow distribution component includes a first annular body and a second annular body, a plurality of L-shaped plates are obliquely arranged between the first annular body and the second annular body, and a gap is arranged between two adjacent L-shaped plates. The hot air passes through the gap between the two adjacent L-shaped plates, and then continues to flow toward the upper part of the drying device after being evenly dispersed, so as to dry the coated product. The first airflow component of the above structure is reasonably designed and simple in structure, realizes even dispersion of the airflow, and avoids the formation of airflow clusters.

[0013] Since the second airflow distribution component includes a disc body, a plurality of through holes are arranged at equal intervals on the disc body. The hot air is evenly dispersed through the plurality of through holes on the disc body, and then fully contacts with the coated product for drying. The second airflow distribution component is reasonably designed, so that the hot air is evenly dispersed, the formation of airflow clusters is avoided, and the uniformity of the product coating is ensured.

[0014] Since the hot air supply device includes a blower, the air inlet of the blower is provided with a filter cover, the air outlet of the blower is connected to the heater, the air outlet of the heater is connected to the filter, and the air outlet of the filter is connected to the air inlet of the drying device. In actual production, the blower introduces the wind from the surrounding environment into the interior of the heater, and dust can be effectively removed through the filter cover. The wind entering the interior of the heater exchanges heat with steam, and then enters the filter to further remove dust, and finally enters the interior of the drying device for drying the coated product. The hot air supply device of the above structure is reasonably designed and can supply the hot air required by the coated product.

[0015] Since the air outlet of the drying equipment is connected to the filter device, and the air outlet of the filter device is connected to the induced draft fan, the coating material can be intercepted by the filter device to prevent the coating material from being discharged with the hot air, thereby avoiding waste of resources.
