The automated assembly line effectively solves the problems of uneven manual processing, easy contamination, low output, and high waste rate. It is suitable for small, medium, and large food processing enterprises, supporting customized production of smooth peanut butter, crunchy peanut butter, and flavored peanut butter. The following is a detailed introduction to the core equipment of each link.

How the Peanut Butter Making Machine Line Working-Hebei Beibu Machinery Technology Co.,LTD

1. Peanut Roasting Machine: Core Equipment for Flavor Shaping

The peanut roasting machine is the first key equipment of the entire production line and the decisive factor for the nutty flavor of peanut butter. Raw peanuts have high moisture content, faint taste, and hard texture, which cannot be directly processed into high-quality peanut butter. Controlled high-temperature roasting can evaporate excess water inside peanuts, break down internal starch and fiber structures, promote the release of natural peanut oil, and produce rich caramelized and nutty aromas, laying a foundation for subsequent processing and final taste formation.

Industrial peanut roasting machines are mainly divided into continuous chain plate roasters and rotary batch roasters, both adopting food-grade SUS304 stainless steel structure that meets FDA and CE food safety standards. The equipment uses hot air circulation heating technology to realize three-dimensional and uniform heating, completely avoiding local burnt or under-roasted problems caused by traditional single-sided heating. Operators can accurately adjust the roasting temperature (150℃-210℃) and processing time according to peanut varieties, water content, and target roasting degree (light, medium, dark roast).

In actual industrial production, standardized roasting parameters can effectively improve peanut oil yield and reduce subsequent grinding resistance. The fully automatic feeding and discharging design realizes seamless docking with the subsequent cooling equipment, greatly improving production efficiency. At the same time, the equipment is equipped with an intelligent temperature control system and heat insulation structure, which not only ensures stable processing quality but also reduces energy consumption and production costs, becoming the standard configuration of modern peanut butter production lines.

2. Peanut Cooling Machine: Key Equipment for Quality Locking

Immediately after roasting, the surface and internal temperature of peanuts can reach 180℃-210℃. If high-temperature peanuts directly enter the peeling process, continuous residual heat will cause secondary over-roasting, leading to bitter taste, dark color, and kernel scorching. In addition, high-temperature peanut skin is soft and tough, which cannot be peeled efficiently, seriously affecting the yield and finished product quality. Therefore, the peanut cooling machine is an indispensable transitional equipment connecting roasting and peeling processes.

This equipment adopts forced air convection rapid cooling technology. Roasted peanuts are evenly laid on a perforated stainless steel conveyor belt, and multi-dimensional circulating cold air quickly takes away surface and internal heat, reducing the peanut temperature to the standard processing temperature of 30℃-40℃ within 5-10 minutes. The adjustable belt speed design can flexibly adapt to different production capacities and roasting temperatures to ensure consistent cooling effect of each batch of materials.

In addition to rapid cooling and flavor locking, the peanut cooling machine also has a built-in dust and debris removal system, which can automatically suck away loose peanut skin debris and surface dust generated during roasting, ensuring the cleanliness of raw materials. Uniform cooling can make the peanut red skin dry and brittle, greatly improving the peeling efficiency of subsequent equipment, reducing peanut kernel breakage rate, and effectively protecting the service life of downstream processing equipment.

3. Peanut Peeling Machine: Essential Equipment for Improving Finished Texture

The red outer skin of peanuts contains a large amount of crude fiber and bitter substances. If not removed completely, it will make the finished peanut butter gritty, dark in color, and slightly bitter, seriously affecting the taste and appearance of the product. The peanut peeling machine is specially used for dry peeling of cooled roasted peanuts, which is the core process to ensure the smooth texture and pure color of high-quality peanut butter.

Industrial peanut peeling machines adopt mature dry friction peeling technology, without adding any water in the whole process, which avoids material moisture reabsorption and bacterial growth, and conforms to food hygiene and fresh-keeping requirements. The equipment is equipped with high-elasticity food-grade rubber opposite-rotating rollers. When peanuts pass through the roller gap, the uniform friction force can completely separate the red skin from the peanut kernels. The matched high-power suction and separation system can automatically collect peanut skin and impurities, realizing automatic separation of kernels and skin.

The roller gap of the peeling machine is adjustable, which can adapt to peanuts of different particle sizes, with a peeling rate of more than 98% and a kernel breakage rate controlled below 3%. The fully enclosed structural design prevents dust overflow, maintains a clean production environment, and meets modern food factory GMP production standards. After peeling, the whole peanut kernels are golden and clean, completely eliminating the bitter source, and laying a solid foundation for making delicate and pure peanut butter.

4. Peanut Grinding Machine: Core Equipment for Paste Formation

The peanut grinding machine, also known as peanut butter colloid mill, is the heart of the entire peanut butter making machine line, directly determining the fineness, smoothness, stability, and taste of the finished peanut butter. All previous pretreatment processes are to create optimal processing conditions for the grinding link.

The equipment adopts dual-stage shearing and grinding technology of coarse grinding and fine grinding. Peeled whole peanut kernels are automatically fed into the grinding chamber. Through the high-speed relative operation of precision rotor and stator, strong shear, friction, and impact force are generated to instantly crush peanut kernels and fully release natural peanut oil. The coarse grinding stage preliminarily breaks the materials to form uniform coarse paste, and the fine grinding stage further refines the particles to make the fineness reach 5-8 microns, realizing ultra-smooth paste texture.

The peanut grinding machine is equipped with a circulating water cooling system, which can effectively control the grinding temperature below 68℃, avoid high-temperature oxidation of peanut oil and protein denaturation, prevent the deterioration of peanut butter flavor, and extend the shelf life of finished products. All contact parts are made of high-standard stainless steel, which is corrosion-resistant, easy to clean, and free of sanitary dead corners. By adjusting the grinding gap, the equipment can produce smooth peanut butter and granular crunchy peanut butter to meet diversified market demands. The whole grinding process is continuous and automatic, with high output and low waste, realizing maximum utilization of peanut raw materials.

5. Peanut Butter Filling Machine: Final Equipment for Finished Product Packaging

The peanut butter filling machine is the final processing equipment of the production line, responsible for quantitative filling and packaging of refined peanut butter, realizing the transformation from semi-finished paste to marketable finished products. Peanut butter is a high-viscosity oily paste, which is easy to drip and foam during filling. Professional filling equipment is required to ensure accurate measurement, clean packaging, and hygienic sealing.

Industrial automatic peanut butter filling machines adopt volumetric piston quantitative filling technology, which is specially designed for high-viscosity nut paste materials. The equipment has adjustable filling volume and speed, which can adapt to packaging containers of different specifications such as glass jars, plastic bottles, and plastic bags ranging from 100ml to 1000ml. The filling accuracy is controlled within ±1%, effectively avoiding the problems of insufficient measurement or excessive filling, ensuring uniform net content of each product and standardized packaging.

Equipped with anti-drip and anti-foam nozzles, the filling machine can effectively prevent paste dripping and air mixing during filling, keep the packaging mouth clean and tidy, and improve the appearance grade of finished products. The fully automatic model can be connected with capping, labeling, and coding equipment to form an integrated packaging production line, realizing unmanned continuous operation, greatly improving packaging efficiency. The food-grade stainless steel body and detachable structure are convenient for daily cleaning and disinfection, avoiding material residue and bacterial cross-contamination, ensuring that the finished peanut butter meets food safety standards and can be directly put into market sales.
