摘要：
The deepfreezer comprises a conveyor comprising rotating rollers between which a space is present for moving the food product, a chamber containing a unit for blowing cold air at a negative temperature upwards between rollers to ensure crusting of the foodstuff located on the rollers. The conveyor further comprises a first device to move in one direction for advancing the rollers linked together in a loop passing through the chamber, and a second device to rotate the rollers on themselves in one direction of reverse rotation of a direction for advancing in the chamber. The deepfreezer comprises a conveyor comprising rotating rollers between which a space is present for moving the food product, a chamber containing a unit for blowing cold air at a negative temperature upwards between rollers to ensure crusting of the foodstuff located on the rollers. The conveyor further comprises a first device to move in one direction for advancing the rollers linked together in a loop passing through the chamber, a second device to rotate the rollers on themselves in one direction of reverse rotation of a direction for advancing in the chamber, and a unit for adjusting the speed for advancing rollers in the advancing direction and the speed of rotation of rollers in the rotation direction opposite to the advanced rotation direction so that the rollers exit from the chamber after a predetermined period after their entry into the chamber, and pass outside the chamber in a heating-up device. The residence time of the foodstuff on the rollers in the chamber is determined by the difference between the speed of advancing the rollers in the advanced direction and the non-zero tangential velocity imparted to the foodstuff by the speed of rotation of the rollers in direction opposite to the advancing direction of rotation of the rollers. The rollers contact with foodstuff at their outer surface, which is metallic. The heating up device comprises a box of water vapor in which the rollers pa
