Automated Coated Peanut Frying Plant Peanut Coating And Frying Production Line

Description:

The peanut coating and frying production line is a food processing line with a high degree of automation. Through the four core processes of coating, frying, deoiling and seasoning, it realizes the continuous production of peanuts from raw materials to flavored finished products. The whole line adopts a modular design, taking into account efficiency and process stability, and can meet the standardized processing requirements of products with different flavors. The following is a functional analysis of each device according to the process flow:

1. Automatic peanut coating machine
Function: Uniformly coat the surface of peanuts with a powdery coating layer (such as starch, seasoning powder or compound powder) to form a protective layer to lock in moisture and provide a basis for subsequent frying and shaping.

Working principle: Peanuts are transported to the inner cavity of the drum through a spiral propulsion system, and atomized slurry or dry powder is sprayed synchronously. The centrifugal force and flipping generated by the rotation of the drum are used to achieve uniform coating adhesion.

Usage features: Equipped with a variable frequency speed regulation system, it can adapt to peanuts of different particle sizes; the coating thickness can be controlled by the linkage of powder flow and drum speed, and the coating completeness rate of the finished product is ≥99%.

2. Peanut continuous fryer
Function: Fry the coated peanuts at a constant temperature to give the product a crispy taste and golden color, while killing microorganisms through high temperature.

Working principle: Use mesh belt continuous conveying, oil tank temperature control (usually 150-160℃), maintain oil temperature stability through the heat circulation system, and frying time is accurately adjusted by the mesh belt speed.

Usage characteristics: Equipped with oil filtration device to reduce residue carbonization, extend the oil life by 30%; heat recovery design reduces energy consumption, and the daily processing capacity can reach 2-5 tons.

3. Peanut oil filter
Function: Quickly separate the floating oil on the surface of peanuts after frying, reduce the oil content of the finished product, and improve the freshness of the taste.

Working principle: Through the combination of multi-layer vibrating screen and negative pressure air cooling system, physical deoiling and surface cooling are achieved simultaneously during the conveying process.

Usage characteristics: The residual oil rate can be controlled below 18%, and the vibration frequency can be adjusted to adapt to different coating strengths; the fully enclosed structure avoids secondary pollution.

4. Peanut Double-Drum Seasoning Machine
Function: Secondary seasoning of de-oiled peanuts to achieve precise addition of salty, sweet or complex flavors.

Working Principle: The main and auxiliary double-drum design is adopted. The main drum sprays liquid seasonings, and the auxiliary drum spreads powdered auxiliary materials. The differential rotation ensures multi-layer coating of seasonings.

Usage Features: The seasoning utilization rate is more than 90%, and it is equipped with an anti-clogging system for the atomizing nozzle; it supports multi-stage programmed seasoning, and it only takes 10 minutes to clean the machine to switch product flavors.

The production line significantly improves the production efficiency and quality stability of peanut products through process connection optimization and intelligent control system. The closed-loop design of coating-frying-de-oiling-seasoning can not only reduce the intensity of manual intervention (the number of operators on the whole line is ≤3 people), but also achieve precise control of key indicators such as oil content, crispness, and flavor concentration, which is particularly suitable for the large-scale standardized production needs of snack food companies.
