Automatic VFFS Salad & Leafy Greens Packaging Machine with Nitrogen Flush

Why Choose This Packing Machine for Vegetables?

Oxidation turns salad brown in hours. To sell fresh cut vegetables in supermarkets, you need to remove oxygen. The LTC Salad Machine integrates a precision Gas Flush System that replaces air with a Nitrogen/CO2 mix, extending shelf life from days to weeks. For fluffy leaves like spinach, we use Ultrasonic Sealing Jaws that seal through product scraps without burning them, ensuring a hermetic pack every time.

Features

• MAP Gas Flush: Residual oxygen monitoring keeps the internal atmosphere perfect for respiration control.

• Ultrasonic Sealing (Optional): Cold welding technology seals through leaf residue, preventing leaks and "burnt leaf" smell.

• Poker / Stuffer Device: A mechanical finger gently pushes fluffy greens down into the bag before sealing to prevent trapping.

• Servo Pulling Belts: Vacuum-assisted belts transport the film smoothly without slipping, even in wet cold-room environments.

Ideal Applications

Designed for fresh-cut produce:

• Salad Mix / Iceberg Lettuce

• Baby Spinach / Arugula (Rocket)

• Coleslaw Mix (Cabbage & Carrot)

• Fresh Herbs (Basil, Parsley)

• Bean Sprouts

FAQs for Salad Packing

Q: Why use Ultrasonic Sealing for salad?

A: Salad leaves often get stuck in the seal. Heat jaws will burn the leaf, causing a bad smell and a weak seal. Ultrasonic jaws seal through the leaf without heat, maintaining package integrity.

Q: Does it work in a cold room?

A: Yes, the machine is built with Anti-Condensation electronics and stainless steel to operate reliably in 4°C environments.
