The semi-automatic peanut candy block production line is designed to process peanuts, walnuts, and other nuts into peanut candy blocks, nut candy blocks, and similar confectionery products. It is an efficient food processing solution suitable for batch production.
By controlling temperature, processing time, and mechanical operations, the line achieves semi-automatic production from roasting, peeling, and mixing to forming, cutting, and packaging. The complete line consists of a roasting machine, peanut peeling machine, jacketed kettle, mixer, block pressing machine, 7-type forming and cutting machine, and packaging machine. Different models can be configured based on capacity requirements, with outputs ranging from 50 to 200 kg per hour. Operation is simple and well-suited to small and medium-sized food processing businesses.
With a compact structure, easy operation, stable output, uniform sugar distribution, neat block shapes, and a hygienic, easy-to-maintain design, this production line helps reduce labor costs while improving overall production efficiency, making it ideal for SMEs and startup factories.
What Are the Raw Materials of Peanut Candy Blocks?
Peanut candy blocks are commonly known as Peanut Brittle in Europe and the United States, Groundnut Chikki in India and South Asia, and also referred to as Peanut Candy or Peanut Bars in other regions. The main raw materials include high-quality peanuts, white granulated sugar, maltose, or glucose syrup. Small amounts of edible oil or flavoring may be added to adjust taste and texture.
After roasting and peeling, the peanuts are fully mixed with the cooked sugar syrup, then pressed and cut into standard candy blocks. Raw material selection directly affects the texture, color, and flavor of the final product. For this reason, fresh peanuts and evenly cooked syrup are essential to ensure consistent product quality.
Finished Peanut Candy Blocks
The finished peanut candy blocks are golden to light brown in color, with a uniform block shape and evenly distributed sugar. They offer a crisp texture with a balanced sweetness that is not overpowering. The products have good shape retention and packaging compatibility, making them suitable for retail packs, gift boxes, and bulk sales.
Semi-Automatic Peanut Candy Block Production Line – Process Flow
Heats raw peanuts to evaporate excess moisture, enhancing aroma and flavor. Uniform heating ensures every peanut is evenly roasted, providing an ideal base for peeling and mixing while preventing raw or burnt flavors.
Removes the skins of roasted peanuts, producing clean, smooth peanuts. This reduces roughness in the candy blocks caused by leftover skins and improves the binding between peanuts and sugar syrup, ensuring a consistent texture.
Cooks the sugar syrup using jacketed heating and mixes it with peanuts. With even heat and adjustable temperature, the syrup reaches the ideal concentration, fully coating peanuts and creating a uniform candy mixture ready for pressing and cutting.
Mixer
Thoroughly mixes the cooked sugar syrup with roasted, peeled peanuts. Continuous and even mixing ensures every peanut is evenly coated, preventing syrup clumps and ensuring consistent sugar distribution for stable flavor and texture in the final product.
Block Pressing Machine
Compresses the mixed peanut-sugar mass into preliminary blocks, providing standard shape and density for cutting. Adjustable pressure and speed create firm blocks that hold together, improving cutting efficiency and resulting in crispy, evenly structured candy blocks.
7-Type Forming and Cutting Machine
Cuts the pressed blocks into standard sizes. The machine’s ejector function separates the cut blocks while maintaining neat shapes, preventing breakage or sticking, and ensuring uniform size and attractive appearance for packaging and sale.
Packaging Machine
Automatically packages the finished peanut candy blocks, maintaining hygiene and transport safety. The machine can handle single or multiple blocks, reducing manual labor, preventing secondary contamination, and improving production efficiency and packaging consistency, making the candy blocks ready for storage, transport, and sale.
Working Principle of the Peanut Candy Block Production Line
The semi-automatic production line works by first roasting peanuts in the roasting machine to remove moisture and enhance flavor. After peeling, the peanuts are thoroughly mixed with cooked sugar syrup in the mixer. The block pressing machine compresses the mixture into semi-finished blocks, which are then cut into standard sizes by the cutting machine. Finally, the packaging machine seals the finished candy blocks.
The entire line operates in a continuous, semi-automatic process, with manual work mainly limited to feeding raw materials, collecting the output, and basic equipment operation.
Advantages of the Semi-Automatic Peanut Candy Block Production Line
Compact Structure: The line consists of a roasting machine, peeling machine, jacketed kettle, mixer, block press, cutting machine, and packaging machine. It occupies minimal space, offers flexible layout, and is easy to install and operate in small and medium-sized factories or startup workshops.
Easy Operation: The block press and cutting machine are designed as small standalone units, requiring no complex chain systems or large conveyors. The roasting machine, mixer, and jacketed kettle are intuitive to operate, allowing workers to handle roasting, mixing, pressing, and cutting after short-term training.
Stable Output: The block press can produce 150–300 kg/h, and the cutting machine 50–100 kg/h, ensuring consistent daily output. The candy blocks are firm, uniform, and meet the production needs of small to medium-scale operations.
Uniform Block Shape: The 7-type forming and cutting machine with ejector function ensures consistent block size and smooth edges. Sugar syrup mixed evenly in the jacketed kettle guarantees uniform coating, producing a crisp and consistent texture.
Easy Maintenance: All equipment in contact with raw materials is made of SUS 304 stainless steel and designed as standalone units for easy disassembly and cleaning. The block press, cutting machine, and mixer support local maintenance and quick cleaning, improving overall hygiene.
Flexible Customization: Pressure, speed, and cutting specifications of the block press and cutting machine are adjustable. Batch size and heating temperature of the jacketed kettle and mixer can be modified. The line can be customized according to output and candy size, ideal for small businesses and startup factories requiring flexible production.
Semi-Automatic vs. Fully Automatic Peanut Brittle Block Production Line
In the semi-automatic Peanut brittle block production line, the block press and cutting machine are small standalone units, not using a large chain-type design. The other equipment—roasting machine, peeling machine, jacketed kettle, mixer, and packaging machine—is configured the same as in a fully automatic line. As a result, the semi-automatic line requires lower investment and offers more flexible operation.
