Salad Processing Lines


Processing Lines for Salads and Leafy Greens

Suitable For All Types of Leafy Vegetables


Quadra's salads and leafy greens processing lines adhere to the strictest quality standards, ensuring that you receive absolutely clean, ready-to-eat leafy vegetables. The entire line is equipped with the most efficient salad processing machines for chopping, washing, drying, sorting, and packing all sorts of leafy products including lettuce varieties, cabbages, spinach, parsley, celery, and much more.

The salad production line is built to match your desired production speed, which can range from 600 kg/hr to 3000 kg/hr or more. The machines are designed to be versatile, allowing you to start small and expand your processing line later as needed.


Salad Washing Machines


Multi-Stage Washing and Sanitizing

Our salad processing equipment is designed to extend the shelf life of your products and keep them fresh for longer. For leafy vegetables with a high quantity of dirt and germs, multi-stage washers are desirable to thoroughly clean them. A two-stage washing system is used to assure a zero-germ count by sanitizing the products first and then washing them in extremely cold water (near 0°C). If your products are exceptionally dirty, then a three-stage washing system with a flycatcher will undoubtedly eliminate any dirt, germs, or insects present in the batch.

Salad Processing Steps

  Preparation Station


Manual Cutting Lettuce

The preparation station is installed at the entrance of the cutting machine. It is equipped with cutting boards and garbage funnels for workers to de-core, de-stem, and precut the leafy vegetables before introducing them to the cutting machine. The preparation station is available with 2, 4, or 6 positions for workers.

  Cutting Machine


Lettuce Cutting Machine

Our vegetable cutting machines are excellent for chopping leafy greens like lettuce varieties, cabbages, and herbs into adjustable sizes from 1 mm to 55 mm at speeds of up to 3000 kg/hr. The cutting shapes and sizes can be regulated instantaneously by means of a user-friendly touch screen mounted on the machine.

  Bubble Washing


Salad Washing Machine

The cut or whole salads are dumped into the washing machine whose first compartment is a tank filled with water. The water in the basin is agitated using powerful pumps and nozzles along its sides. The leaves are submerged and mixed in the water, then whirl around for several minutes to remove all the dirt on their surface. The water temperature can be regulated to a cold range that is ideal for washing mixed leaves. Small leaves and insects can be filtered out with a flycatcher installed on the machine, and sanitizing agents and detergents can be added to the water solution if necessary.

  Sprinklers


Lettuce Washing Machine

The second section of the washing machine is a vibrating sieve with sprinklers mounted on top. The sprinklers give the leaves a second shower of clean water to ensure that they are thoroughly rinsed. The sieves filter away the sand, debris, and insects, and the unclean water is recycled back into the washing tank. The cleaned leaves then continue to the next cleaning station (in a multi-stage setup) or to an automatic basket filling system.

  Automatic Basket Filling


Basket Filling System

The ACBM is a stainless-steel automatic carousel basket machine that is installed after the washing machine to collect the washed leafy vegetables in baskets. It has an optical sensor that detects when a basket is full and automatically rotates the carousel to the next slot, revealing a new empty basket. The ACBM is a useful system that reduces human intervention, time wasted, and product waste.

  Centrifugal Drying


Centrifugal Dryer for Vegetables

The centrifugal dryer is excellent for drying fresh cut and leafy vegetables efficiently. The washed products are placed in a basket in the dryer, which spins rapidly to drain water and moisture from the veggies. The dryer has an adjustable rotational speed and time, which can be controlled based on the products at hand to ensure that they do not spin too fast for too long and become damaged. This dryer also features a reverse function, which is especially useful for drying salads by spinning them in both clockwise and anti-clockwise directions.

  Optical Sorting


Salad Sorting Machine

A salad sorting machine can be seamlessly integrated along the salad processing line to ensure that your finished products are 100% fresh and defect-free. The sorting machine features high resolution cameras, a laser vision system, and pulsed LED technologies to detect the most difficult flaws such as discolored leaves, damp leaves, cores, and foreign objects like stones, plastic, and insects. The optical sorters can operate at exceptionally high speeds ensuring that your line's performance and efficiency is always at its best.

  Packing Machine


VFFS for Packing Leafy Vegetables

Once the salads have been chopped, washed, cleaned, and dried, they are ready to be packed in sealed trays, pillow bags, pouches, vacuumed bags, or any other type of packaging you may prefer. This is possible using our wide selection of automatic packaging machines which include flow pack machines, vertical packing machines, tray sealers, and vacuum packing machines.
