High Recovery and Hygiene for Green Bean / Snap Bean Processing Lines

Air cleaners, cluster busters, snippers, UBRs, various slicers, blanchers, primary packaging, retorts,  case packing and palletizing robotics, and more. 

Several of our engineers came from Hughes equipment, and know how all about green bean / snap bean processing.

Weather you want snipped for fresh, whole or cut for frozen, French-cut for canned beans or anything in-between, we custom design a complete processing and packing line for your specific needs. 

Here are just a few of the options we have to automate your line, increase your capacity, or improve your product hygiene. Let’s talk about your needs.

General Line

Industrial green bean processing typically involves several stages, including sorting, cleaning, blanching, and packaging. Here is a general overview of the process:

  1. Infeed: Raw product goes through pre-cleaning stages, such as through an air cleaner and/or cluster buster.
  2. Cleaning: The green beans (or snap beans) are then washed thoroughly to remove any dirt or debris. This is typically done using a flume, jet or bubble washer.
  3. Sorting: The green beans are first sorted to remove any damaged or discolored beans. This is typically done using an optical sorter. Some plants have optical sorters after several process steps.
  4. Cutting: Some processors split all or partial loads into cross-head, french or other cutters for that cut. 
  5. Blanching: For canned beans. The green beans are blanched in boiling water or steam for a short period of time (usually 1-3 minutes) to deactivate enzymes and reduce microbial activity. This helps to preserve the quality and shelf life of the beans.
  6. Cooling: Also for canned beans. The blanched green beans are then cooled quickly using cold water or air to stop the cooking process.
  7. IQF Tunnel: For frozen product, fed into a tunnel freezer to freeze and help mitigate block freezing.
  8. Packaging: The cooled green beans are then packaged into bags, cans, or other containers, often with the addition of salt, vinegar, or other preservatives to enhance flavor and extend shelf life.
  9. Quality control: Throughout the processing stages, quality control checks are performed to ensure that the green beans meet the required standards for appearance, texture, flavor, and safety.

There are many ways to process beans, and we work with you to determine the right process steps, equipment and line design for your unique output needs.
