Foreign Substance Separation Equipment for Food

Are there sufficient countermeasures against foreign matter contamination and measures for sorting?
Consumers are highly conscious of food safety and security.
In particular, a high level of food hygiene control is required for foreign substances mixed in food.

For more than 35 years, Hitachi Zosen has been involved mainly in the manufacture of equipment for sorting foreign matter contained in foods. We provide equipment for dry foods and wet products.

  • Delivery record: More than approx. 500 companies / More than approx. 2,000 machines

Vibration wind sorting device

Automatically removes foreign matter from the product using the force of vibration and the force of wind!
The mechanical sorting device can automatically remove foreign substances from the product through size sorting using the force of vibration and specific gravity sorting using the force of wind.

Vibration wind sorting device (N-SJT/LVSJ/KVSJ)

N-SJT
LVSJ
KVSJ
Features
  • Optimal for sorting by size, sorting by specific density, and classifying products.
  • We offer a lineup of vibration sorting according to the product size.
    Example)
    • Powders and small products (small whitefish, spices, FD vegetables, etc.): Electromagnetic vibration
    • Larger products (dried baby sardines, sweets, dried shiitake mushrooms, etc.): Crank vibration
  • Optimal for removing hair, vinyl pieces, stones, etc., in specific density sorting.

Vibration sorter (LVS/LVS-T/KVS/AVS)

LVS
LVS-T
KVS
AVS
Features
  • A device specializing in sorting by size and classifying products.
  • We can propose vibration sorting that corresponds to various product sizes. (Electromagnetic vibration, crank vibration, air vibration)
  • Foreign matter sorters using electromagnetic vibration and crank vibration can only be used for dried foods.
  • The foreign matter sorter using air vibration is compatible with products that contain moisture.
Example of sorting
  • Seafood: Small whitefish, dried baby sardines, seaweed, wakame seaweed, kelp, etc.
  • FD vegetables: FD vegetables (carrots, onions, green onions), etc.
  • Spices: Pepper, chili peppers, etc.
  • Sweets: Mochi rice crackers, dry sausage, gummies, etc.
  • Industrial products: Industrial powder, pellets
Example of substances targeted for removal
  • Different fish species such as squid, octopus, and shrimp
  • Plastic pieces
  • Wood pieces
  • Vinyl pieces
  • Contamination
  • Hair, fiber pieces (specific gravity selection)
  • Stone (specific gravity selection)

We also perform sample tests as necessary. Please start by contacting us with any questions that you may have.
