Efficient Raw Material Unloading and Primary Cleaning
Raw materials are unloaded using a specialized system featuring a hopper and Z bucket elevator. The materials are collected in the receiving hopper, where grid bars prevent large particles and foreign impurities from contaminating the product. Each Z bucket elevator includes an electromagnetic feeder, protecting the moving buckets and ensuring safe, efficient transfer.
After unloading, the peanuts move to the destoner, where stones, stalks, and other foreign impurities are effectively removed, preventing contamination in the following processing stages and ensuring a clean product flow.
Multifunctional Continuous Roasting Machine
The equipment supports two main functions:
-Drying/Dehydrating: Operates at low temperatures between 85-95°C.
-Baking/Roasting: Works at high temperatures ranging from 100-180°C.
The roasting equipment features two distinct heating zones, with gas burners located at the top of the roaster. Heated air is directed onto the roasting belt for even distribution. Raw peanuts are fed into the roaster from the destoner’s outlet via an adjustable motor that controls material thickness. Once the peanuts are uniformly detained, the roasting belt starts, guiding the peanuts evenly through the heat zones. The hot air flow alternates in direction between zones, allowing efficient humidity evaporation and ensuring uniform roasting.
After roasting, the peanuts enter the Transition Zone, separating the high-temperature roasting area from the cooling section. This design maintains a sealed heating zone, minimizing heat loss and enhancing cooling efficiency.
In the cooling zone, peanuts are cooled by high-pressure fans. Double cooling sections are installed for roasters with four or more heating zones, ensuring effective temperature reduction. The finished peanuts are typically cooled to near ambient temperature (ambient +2°C) before being discharged via a vibrating conveyor.
Versatile Split Peanut Blancher - Efficient Blanching for All Peanut Sizes
The Split Peanut Blancher is designed to split and blanch roasted peanut kernels into halves or smaller pieces. It is also called a Belt Blancher. Due to its structural design, this blancher can also break roasted peanuts into smaller fragments.
The roasted peanut kernels are fed into the receiving hopper of the split blancher. Under the guidance of the feeding plate, the peanuts enter the blanching chamber, which consists of two silicone belts. These belts rotate at high speed, rubbing the peanut kernels, and causing them to split and peel. The feed spiral pushes the peanuts forward, dropping them onto a vibrator. Through the vibration screening process, the air cyclone effectively sucks away the red skins, achieving the separation of peanut kernels and skins.
Our split peanut blancher can reach an output of up to 1,200 kg/hr. If the entire peanut butter production line capacity is below 1,000 kg/hr, then one unit of the split blancher is sufficient.
Color Sorter, X-ray Inspection System, Metal Detector, and Accessories

Streamlined Multi-Ingredient Feeding Solution for Peanut Butter Manufacturing
Peanut butter is immensely popular worldwide, primarily due to its rich nutrient profile from peanuts, delicious taste, and ease of consumption. However, the quality of the original, unprocessed peanut butter faced several challenges, including poor spreadability, oil separation on the surface, high viscosity, and a short shelf life. To improve these characteristics, manufacturers began to add specific ingredients to maintain stability without compromising nutritional value. In 1968, the U.S. Food and Drug Administration (FDA) set strict standards for peanut butter additives, limiting them to 10% of the final product and defining criteria for oil content, protein, and moisture levels.
A peanut butter production line typically incorporates a multi-phase dispersion system where both solid (protein) and liquid phases (water, oil) are involved. After grinding, peanuts contain around 52.9% oil and 2% moisture, forming a water-in-oil emulsion. Over time, oil separation, known as layering, occurs due to the tiny dispersed particles and their increased surface area. Stabilizing the oil dispersion in peanut butter is crucial for extending its shelf life and maintaining consistent quality.
To improve stability and texture, manufacturers may add specific stabilizers, such as hydrogenated peanut oil and emulsifiers like monoglycerides and diglycerides. For example, hydrogenated peanut oil can be added by blending 85% natural peanut oil with 15% highly hydrogenated oil (melting point 136.5–140°F), which prevents oil separation. Another option is to mix a small amount of hydrogenated oil directly into the roasted and blanched peanuts, maintaining stability while keeping hydrogenated content below 0.75%.
Emulsifiers like monoglycerides and diglycerides play a pivotal role in stabilizing peanut butter by preventing oil separation. They work by forming a stable electric double layer around the particles, which helps them resist separation over time. The MYVATEX Mon-oset food emulsifier, a refined glycerol-acid ester, is another popular option, forming a needle-like crystalline matrix in the butter that prevents oil segregation. The choice of stabilizer may vary depending on seasonal conditions, packaging, filling temperature, and storage temperature. For instance, rapeseed hardened oil is often used when the filling temperature is low (33–40°C), while hardened cottonseed oil is preferred for higher temperatures (79–54°C).
In addition to these stabilizers, manufacturers may add ingredients like salt, sugar, jam, or chocolate paste to meet diverse consumer preferences, enhancing flavor and variety in peanut butter products. These added ingredients are precisely measured to ensure that each batch meets food safety standards while maintaining a stable texture and flavor profile.
Ingredients Feeding System
A well-designed Ingredients Feeding System is essential in peanut butter manufacturing for the accurate and flexible addition of these stabilizers and flavor enhancers. This system allows for the seamless integration of multiple ingredients, maintaining the ideal balance for quality and consistency. A professional feeding system features flexibility, multi-functionality, easy operation, and stable performance. It enables manufacturers to add ingredients like hydrogenated oils, emulsifiers, and flavor components with precision, ensuring uniform distribution and thorough mixing.

Peanut Butter Cooling Section: Ensuring Premium Quality and Longevity
Peanut butter cooling is a crucial step in determining the texture, quality, and shelf life of the final product. After the first-stage milling, the outlet temperature of peanut butter is typically around 82°C, while the second-stage milling reduces it to between 60°C and 77°C. From here, the peanut butter enters a well-designed cooling process that consists of a mixing tank, a vacuum tank, and a scraper heat exchanger, gradually cooling the product to below 49°C. Proper cooling is essential for the crystallization of oils and fats, which prevents phase separation. Ideally, the filling temperature of peanut butter should be between 29°C and 43°C to maintain product stability.
Peanut Butter Cooling Process:
Mixing Tank: The mixing tank serves as the initial cooling stage. It ensures uniform pre-cooling of the peanut butter by continuously agitating the product. This helps maintain a consistent texture and evenly distributes the temperature, reducing the risk of hot spots. The tank is equipped with an efficient mixing mechanism and a cold water jacket for controlled cooling.
Vacuum Tank: Following pre-cooling, the peanut butter is transferred to the vacuum tank, which plays a dual role. It removes trapped air bubbles, enhancing the product’s density and improving texture. The vacuum environment also reduces the risk of oxidation, extending the shelf life of the peanut butter. This step is essential in preventing air pockets, which can lead to uneven cooling and potential quality issues.
Scraper Heat Exchanger: The cooled and degassed peanut butter then enters the scraper heat exchanger, which quickly reduces the temperature to below 49°C. The scraper heat exchanger is designed for high-efficiency cooling, utilizing a cold water medium circulated through the system. The scrapers continuously remove the cooled product from the walls, ensuring even heat transfer and preventing any product buildup, which can lead to inconsistencies.
