Description

Technical Field

[0001] This utility model belongs to the technical field of food processing equipment, specifically relating to an economical and environmentally friendly electromagnetic roasted nut automatic production line. Background Technology

[0002] In the food processing industry, the demand for roasted nuts and seeds (such as sunflower seeds, peanuts, and nuts) continues to grow. Traditional roasting equipment mostly uses resistance heating or gas heating, with a thermal efficiency of only 30% to 40% and poor heating uniformity, resulting in high energy consumption and increased production costs. The debris and impurities generated during the roasting process lack effective treatment, which does not meet the requirements of current green manufacturing standards. Material metering, conveying, roasting, and cooling rely on manual operation or semi-mechanized control, resulting in problems such as poor metering accuracy, low production efficiency, and large fluctuations in product quality. Traditional roasting machines lack precise temperature control systems and material movement trajectory designs, which easily lead to quality defects such as burning and undercooking. Moreover, the cooling process relies on natural heat dissipation, which takes an average of 30 to 60 minutes, seriously affecting the production cycle. Utility Model Content

An electromagnetic heating coil 315 is located near the bottom of the material cylinder 301 and is mounted on the base 308. It is used to heat and roast the material inside the material cylinder 301. The motor 309 drives the material cylinder 301 to rotate via a chain 311, causing the material to tumble continuously inside the material cylinder 301, achieving uniform heating and improving the quality of the roasted goods. The variable-diameter discharge port 312 facilitates the smooth discharge of material, and the support rollers 313 ensure the stability of the material cylinder 301 during rotation and reduce equipment wear.The electromagnetic heating coil 315 has advantages such as high heating efficiency, energy saving and environmental protection.

A second inlet 503 is provided on the side of the outer casing 501 near the roasting unit 3, which is connected to the discharge end of the second elevator 4 to receive the roasted materials. A third outlet 504 is provided on the other side of the outer casing 501, which is connected to the inlet end of the third elevator 6 to transport the cooled and impurity removed materials out. Several blowers 505 are provided at the bottom of the outer casing 501. The blowers 505 blow air into the outer casing 501 to cool the materials on the conveyor belt 502. An air outlet 506 is provided at the top of the outer casing 501. 06 is equipped with a blower 507, and a dust collector 508 is installed at the air outlet of the blower 507. The blower 507 draws out the air containing impurities and dust from the outer casing 501, and discharges it after being filtered by the dust collector 508, achieving the dual functions of cooling and impurity removal. The setting of the blower 505 can quickly reduce the temperature of the material, so that the roasted material is cooled in time, avoiding the impact of high temperature on subsequent packaging and storage. The combination of the blower 507 and the dust collector 508 can effectively remove impurities and dust from the material, improving the quality and purity of the product. At the same time, the use of the dust collector 508 reduces dust emissions, meets environmental protection requirements, and protects the production environment and the health of operators.

The blower 505 at the bottom of the outer shell 501 blows air into the interior to cool the material. At the same time, the fan 507 at the top of the outer shell 501 draws out the air containing impurities and dust, which is filtered by the dust collector 508 and then discharged, realizing the dual functions of cooling and impurity removal. The processed material is discharged from the outlet 504 and conveyed to the packaging machine 7 by the third elevator 6 for packaging. In the entire production process, the PLC control cabinet 8 is electrically connected to each piece of equipment, receives sensor signals from the weighing and metering machine 101, the temperature measuring thermocouple 316, etc., and sends instructions to each piece of equipment according to the preset program and control logic, realizing the full-process automated control from material storage, lifting, roasting, cooling and impurity removal to packaging, reducing manual intervention and improving production efficiency.
