Filling Blueberries

Filling Blueberries
Frozen blueberries are generally used in the production of pie filling, pastries, and jam. Some are packed in retail-sized plastic pouches and sold as such as retail. The usual procedure is to freeze the cleaned and inspected berries trays that are placed on racks and move through a cold-air tunnel.

The frozen berries are then run through a machine that breaks up clusters of the frozen fruit and the frozen product is packed volumetrically into metal cans holding about 20lb (9.1 kg) of berries.

The cans are closed with slip covers and placed in frozen storage. Some frozen berries may be mixed with dry sugar (4 parts berries to 1 part sugar) or with 50% sugar solution, placed in large metal slip cover containers, and frozen in bulk in cold –air rooms.
