Abstract
The invention provides a device and a method for conveying and treating food items in liquid in a tank. The device is designed for transferring and treating food items in liquid simultaneously, such as cooling, thawing or treating the food items with additives. The blade of the invention is a dual action blade as it both advances the food items along the container as well as creating repeated forward and backwards pushing of the items as the blade is rotated.
Claims19
An apparatus for transferring and treating food items in liquid, said apparatus comprising:
- a container
- a spiral shaped blade mounted to a rotation axis for advancing the food items from one end of the container to the other,
- one or more fluid inlets and one or more fluid outlets for feeding liquid in and out of the container,
- wherein the spiral blade has alternating positive and negative radial bends along the length of the spiral blade.

A method for transferring and treating food items in liquid, the method comprising the steps of:
- transferring the food items to a container with a spiral shaped blade mounted to a rotation axis for advancing the food items from one end of the container to the other, said container further comprising one or more fluid inlets and one or more fluid outlets for feeding liquid in and out of the container,
- advancing the food items from the in-feed end to the out-feed end of the container,
- transferring the items out of the container
- wherein the spiral blade has alternating positive (forward) and negative (backward) radial bends along the length of the spiral blade, thereby alternately changing the direction of the spiral blade with respect to its advancing direction, such that the food items are pushed backwards and forwards depending on the direction of the blade.
