Introduction to Common Preprocessing Machines Before Food Drying

1. Bubble Washing Machine

The bubble washing machine handles the first step of the whole preprocessing line.

How it works: High-pressure blowers create rolling bubbles inside the water tank. The bubbles wash material surfaces. High-pressure sprays work together to remove dirt and pesticide residues.

✅ Suitable materials: onions, potatoes, garlic, carrots, leafy greens, many kinds of fruits

✅ Advantages: gentle cleaning that protects skins. The whole machine uses 304 food-grade stainless steel. You can take parts apart for cleaning. It can connect with a lifting machine to send materials straight to cutting equipment next in line.

2. Onion Slicing Machine

Cutting onions by hand stings eyes and slows work. Hand-cut onion strips also have uneven thickness.

Commercial onion slicing machines let you adjust strip thickness and produce uniform onion strips.

✅ Use cases: ready-to-cook meals, salads, frozen vegetables, sauce factories

✅ Features: adjustable gaps between cutter sets. It squeezes less onion juice out during cutting.

3. Potato Strip & Slice Cutter

This multi-purpose machine cuts potatoes into strips or slices. Just swap molds to switch between these two cuts.

It fits fresh-cut potato, frozen French fry and potato chip production.

✅ Output: neat strips or slices with low breakage rates

✅ It also works for carrots, cassava and sweet potatoes

4. Garlic Slicing Machine

Industrial garlic slicing machines make evenly thick garlic slices. These slices go into pickling, garlic drying and seasoning production.

Hand-sliced garlic varies a lot in thickness. Uneven slices lead to inconsistent pickling and drying results.

✅ Adjustable slice thickness

✅ Low breakage rate to cut raw material waste
