Key Applications
This versatile production line is suitable for processing a wide range of ingredients:
-
Nuts: Peanuts, almonds, cashews, hazelnuts, walnuts, and macadamias
-
Seeds: Sesame seeds (for tahini), shea nuts
-
Other: Cocoa beans (for chocolate spreads), soybean paste
Complete Production Process
The small scale peanut paste production line integrates several essential machines into a streamlined workflow:
1. Peanut Roaster
The process begins with a rotating drum roaster that evenly heats raw nuts at controlled temperatures (typically 150- 170C for 20–30 minutes). The operator can preset temperature parameters to achieve optimal roasting that brings out the natural flavor and aroma of the nuts .
2. Cooling Belt Conveyor
After roasting, peanuts are conveyed through a cooling belt equipped with fans that rapidly reduce the temperature, preventing further cooking and preparing the nuts for efficient peeling .
3. Peanut Peeling Machine
Using emery roller friction, this machine removes the red seed coat with a peeling rate exceeding 98%. An integrated fan suction system collects the removed skins, leaving clean, split peanut halves ready for grinding .
4. Peanut Butter Grinding Machine (Colloid Mill)
The core of the production line, this machine uses a stator-rotor system to grind peanuts into smooth paste. The fineness is adjustable (typically 2–100 microns or 100–150 mesh), allowing production of both smooth and crunchy textures. Grinding temperature is controlled around 68–85°C to preserve nutritional value and flavor .
5. Storage & Mixing Tank
Made of double-layer stainless steel, the storage tank can heat and maintain the temperature of the peanut paste while mixing ensures homogeneity. This step is crucial for achieving consistent texture throughout the batch .
6. Filling Machine
The final stage features a semi-automatic or automatic filling machine that dispenses precise volumes (300–1000 ml) into bottles, jars, or pouches at speeds of 20–60 containers per minute
Key Features & Technology of compact peanut butter machine
Complete Integration
A turnkey solution from raw material to finished product, eliminating the need to source individual machines separately.
Stainless Steel Construction
All food-contact parts are manufactured from SUS 304 stainless steel, ensuring corrosion resistance, easy cleaning, and compliance with international food safety standards .
Adjustable Fineness Control
The grinding system features adjustable stator-rotor gaps, allowing operators to switch between chunky and ultra-fine textures (as fine as 2–100 microns) to suit different market preferences .
Modular & Expandable
Individual machines can operate independently or as an integrated line. The modular design allows easy maintenance, replacement, or future upgrades to higher capacity systems .
