Cracking the Core: Inside the World of Split Blanched Peanuts Processing

In the ever-evolving snack industry, peanuts have carved a niche as one of the most loved and versatile ingredients. Whether it’s a quick protein-packed bite or a rich addition to savory dishes, peanuts — especially bold peanuts — are in high demand globally. But before these humble groundnuts make it into your favorite snack or food product, they undergo a meticulous process. Among various forms, split blanched peanuts are particularly sought-after in the food manufacturing sector for their clean appearance, texture, and ease of use.

Let’s take a deep dive into the journey of groundnuts from raw to refined — not roasted, but split and blanched — and explore the precise steps involved in this high-value manufacturing process.

🌱 What Are Split Blanched Peanuts?

Split blanched peanuts are whole peanuts that have undergone a de-skinning (blanching) process and are split into halves. Unlike roasted peanuts, these are not heat-cooked for flavor, but instead prepared specifically for further manufacturing use in confectionery, bakery, and ready-to-eat snack applications.

🏠 The Process Flow: From Raw Groundnut to Split Blanched Perfection

🛠️ Detailed Process Explanation

1. Raw Groundnut Procurement

High-quality bold peanuts are sourced directly from trusted farms. These large kernels are ideal for splitting due to their size and uniformity.

2. Cleaning & Destoning

Foreign materials like dust, stones, and plant debris are removed using vibratory cleaners and air blowers to ensure only pure groundnuts proceed to the next stage.

3. Grading & Sorting

Peanuts are sorted based on size, with only those fitting the specification for split blanched peanuts retained for processing.

4. Shelling

The outer shell is mechanically removed, ensuring minimal breakage and maximum yield of whole kernels.

5. Roasting for Blanching

Unlike snack roasting, this controlled roasting loosens the skin without adding flavor. The goal is efficient blanching, not taste enhancement.

6. Blanching (Skin Removal)

Through heat and friction, the red skins are removed, leaving behind clean, ivory-toned peanuts — perfect for food manufacturing.

7. Splitting into Halves

The blanched peanuts are carefully split into halves, enhancing their usability in bulk production.

8. Color Sorting & Inspection

Automated color sorters eliminate discolored or defective pieces, followed by manual quality inspection for added precision.

9. Metal Detection

Before final packaging, peanuts pass through metal detectors to ensure they meet international food safety standards.

10. Packaging for Bulk Dispatch

Processed split blanched peanuts are packed in bulk in food-grade materials, ready for export or local distribution to snack producers and food processors.
