Peanut coating products are highly valued by consumers for their rich taste and attractive appearance, and are among the most important products in the nut processing industry. To meet market demand, many nut processing enterprises opt for an automated peanut coating production line, enabling large-scale and efficient production.
So what is the core equipment of a complete peanut coating production line?
Peanut coating production line process
The complete process of the peanut coating production line includes: peanut roasting → dry peeling → coating and wrapping → shaking and roasting → seasoning treatment → cooling and cooling → automatic packaging.
This series of processes ensures the efficient transformation from raw peanuts to finished coated peanuts.
Core equipment details
Peanut roasters: enhancing taste and removing moisture
A peanut roaster is used to roast raw peanut kernels to a state suitable for peeling and coating. Its role is not only to improve the taste, but also to effectively remove moisture and extend the shelf life of the product.
Technical features:
- Energy saving and environmental protection: the raw materials in the roasting process are used without direct contact with the flame.
- Temperature control: automatic temperature control system, usually within the range of 160-230°C.
- Uniform heating: roller design ensures that the peanuts are heated uniformly and are not easy to be roasted.
- A variety of heating methods: electric heating, gas heating, coal-fired heating, etc.
The moisture content of the roasted peanuts is reduced to less than 5%, creating optimal conditions for the subsequent peeling process.
Dry peeler: efficient dehulling, reduced crushing
Peanut peeling machine adopts a dry peeling process, featuring a reasonable structure, stable operation, long service life, and high peeling rate.
Functional advantages:
- High peeling rate: peeling efficiency can reach more than 95%.
- Low breakage rate: protects the integrity of the peanut kernel, reduces broken.
- Continuous operation: multiple machines can be connected to improve production efficiency.
The peanut kernel after peeling has a smooth surface and provides high-quality raw material for the coating process.
Peanut coater: uniform coating, diverse flavor base
This equipment is one of the core components of the whole production line, which is used to evenly wrap the prepared slurry on the surface of peanuts. The coating machine can be adapted to different kinds of sugar coating, starch slurry, and batter, to realize diversified flavor development.
Equipment features:
- Adjustable tilting angle: the sugar coating pan has an adjustable tilting angle.
- Direct heating: an electric stove, a gas or other heating equipment can be placed at the bottom of the pan.
- Adjustable temperature: equipped with an independent electric blower, the heat can be adjusted.
- Repeat operation: repeat the operation as many times as needed to increase the thickness of the coating layer.
The coating liquid can be made sweet or savory as needed to meet the needs of different tastes.
Swinging oven: shaping and coloring, attractive colors
Coated peanuts enter the Swing Roaster for a second roasting, which not only sets the shell but also enhances flavor and crunch.
Technical parameters:
- Baking temperature: usually between 180℃-220℃.
- Baking time: usually takes 15 minutes, the specific time depends on the raw materials and the type of machine.
- Capacity specifications: small roaster capacity 60-80kg and 80-100kg, large roaster capacity 200-300kg.
- Automatic discharging: Peanuts will be discharged automatically after setting the heating time and temperature.
The swinging design ensures that peanuts are heated evenly during roasting to avoid localized overheating.
Anise seasoning machine: uniform mixing to enhance flavor
The seasoning machine adopts an octagonal roller structure to mix the seasoning powder with the roasted peanuts fully, so that each peanut can be evenly coated with the flavor powder.
Functional features:
- Multiple ways of seasoning: can be connected to an external powder spraying device, or can also be manually sprinkled.
- Flexible dosage: users can add the required seasoning according to need.
- Hygiene standards: simple structure, beautiful appearance, in line with food hygiene requirements.
- Easy to clean: Stainless steel material is easy to clean and maintain.
The surface of the equipment and the parts in contact with the materials are made of 304 high-quality stainless steel to ensure food safety.
Cooling cart: rapid cooling for easy packaging
Cooling carts are used to cool hot materials after frying or baking in preparation for further packaging. The equipment consists of two parts, a fan and storage, and there are two types of manual discharge and pneumatic automatic discharge.
Equipment specifications:
- Structure: fan machinery and storage part.
- Material standard: stainless steel is used for the part in contact with materials.
- Discharging mode: manual discharging cooling car and pneumatic automatic discharging car.
- Supporting equipment: the automatic type needs to be equipped with an air compressor, air consumption is relatively small.
Rapid cooling ensures that products are packaged at the right temperature to maintain optimum quality.
Granule packaging machine: intelligent measurement, high packaging efficiency
Finally, the cooled coated peanuts will be divided into bags by the granule packing machine according to the set weight. This equipment has the advantages of accurate weighing, firm sealing, and fast speed, which is suitable for various specifications of packaging needs.
Technical advantages:
- Multi-functional control: a control panel to adjust the weight and the number of bags.
- Stainless steel internal parts: internal parts made of stainless steel.
- Sealing effect: heated aluminum block in the sealing area for optimal sealing effect.
- Extended functionality: additional components, such as labeling, bag connection, counting, etc., are available.
Automated packaging improves production efficiency and ensures product packaging quality.
Automation upgrades for more efficient peanut coating processing
A complete peanut coating production line realizes the automation of the whole process from raw material processing to final packaging through the scientific configuration of the above equipment.
Its advantages are saving labor, improving efficiency, stabilizing product quality, and greatly enhancing the competitiveness of the enterprise in the leisure nuts market.
