Pre Cleaner
A heavy duty Peanut Pre Cleaner Machine and Grain Cleaning Machine engineered to strip dust, straw, leaves, soil and light trash from freshly harvested peanuts and grain before drying, storage and processing.

Peanut Pre Cleaner Machine & Grain Cleaning Machine Overview
Swastik Technology’s Peanut Pre Cleaner Machine is the first cleaning stage on a processing line, taking raw, freshly harvested produce and removing the coarse and light impurities that would otherwise travel into the dryer, the store and every machine downstream. Also supplied as a Grain Cleaning Machine, it works with vibrating sieve decks and an air stream to separate straw, leaves, stalks, dust and loose soil from the crop. As an established Peanut Pre Cleaner Manufacturer and Grain Pre Cleaner Manufacturer, Swastik Technology builds each unit as an Industrial Grain Cleaner for continuous duty, with an Automatic Grain Pre Cleaner option for lines that run with steady, controlled feeding. Every Pre Cleaning Machine is designed as Grain Cleaning Equipment that connects directly to the stages on either side of it, with capacity, sieve sizes and air flow selected for the crop and the throughput the plant needs. It sits naturally ahead of our Peanut Dryer Machine and Destoner Machine on a complete line.
What Is a Peanut Pre Cleaner Machine?
A Peanut Pre Cleaner Machine is a cleaning machine placed at the very start of the line to remove the bulk of the trash that arrives with harvested peanuts. Product is fed onto a vibrating sieve, where large material such as vines, stalks and lumps is carried off the top, while fine soil and sand fall through a second sieve. An air stream then lifts away light material such as leaves, husk and dust. What remains is a much cleaner crop that dries faster, stores better and runs through shelling, destoning and grading machines with less wear.
The same principle applies to other crops. A Grain Pre Cleaner is used on wheat, rice and pulses straight from the field or threshing floor, and a Seed Pre Cleaner serves seed companies that need to clean raw lots before conditioning. The job of the pre-cleaning stage is not to produce a finished, graded product, but to take out the rough material cheaply and early so that the finer cleaning machines can work on a crop they were designed for.
How Does a Grain Cleaning Machine Work?
Feeding
Raw, freshly harvested product is fed onto the top sieve at an even, controlled rate.
Coarse Removal
Large material such as vines, stalks and lumps is held on the top sieve and carried to a separate outlet.
Fine Removal
Soil, sand and small particles fall through the lower sieve and are collected separately.
Air Separation
An air stream lifts light material such as leaves, husk and dust away from the product.
Clean Discharge
The pre-cleaned crop leaves through its own outlet, ready for drying, storage or the next machine.

Acts as a Groundnut Cleaning Machine that cleans pods as they arrive in bulk from farms.
Seed Companies & Multiplication Farms
Works as a Seed Cleaning Machine that prepares raw seed lots for conditioning and grading.
Flour Mills & Rice Mills
Serves as a Food Grain Cleaning Machine that cleans wheat and paddy before storage and milling.
Grain Storage & Silos
Removes trash that causes heating and spoilage in stored grain.
Oil Mills & Crushing Plants
Cleans oilseeds before crushing to protect expellers and improve oil quality.
Crops & Materials Cleaned
Benefits of Using a Peanut Pre Cleaner Machine
Removes trash early, so dryers and storage handle only clean product.
Helps crop dry faster, since soil and green leaf hold moisture.
Reduces heating and spoilage risk in storage caused by trash and dust.
Protects shellers, destoners and graders from damage and blockage.
Improves the quality and grade of the final product.
A Grain Cleaning Machine cuts the labour of manual cleaning at intake.
A Grain Cleaning Machine handles large volumes during the peak harvest rush.
Reduces wear on downstream machines, lowering maintenance cost.
