## CPC

- A23N 7/005: {Peeling with steam}
- A23N: MACHINES OR APPARATUS FOR TREATING HARVESTED FRUIT, VEGETABLES OR FLOWER BULBS IN BULK, NOT OTHERWISE PROVIDED FOR; PEELING VEGETABLES OR FRUIT IN BULK; APPARATUS FOR PREPARING ANIMAL FEEDING- STUFFS (machines for cutting straw or fodder A01F29/00; disintegrating, e.g. shredding, B02C; severing, e.g. cutting, splitting, slicing B26B, B26D)

## Abstract

A steam peeling or cooking apparatus for plants, such as potatoes, carrots, celery, red beets, Swedish turnips, apples and the like or for pulp, provided with a substantially cylindrical peeling vessel arranged rotatably about horizontal trunnions, having a supply or discharge opening disposed in one of the head faces, while the peeling vessel is furthermore provided with a steam supply or discharge opening, while the peeling vessel is provided with a stirring gear rotatable about the longitudinal axis.

## Claims

### Claim 1

A steam peeling apparatus for plant products such as potatoes, carrots, celery, red beets, Swedish turnips, apples and the like, comprising:
a substantially cylindrical peeling vessel having a product opening at one end closable by a closure mounted for movement within the vessel and a liquid discharge outlet at the other end;
means mounting the vessel for only tilting movement around a horizontal axis from a normally operating longitudinally inclined position wherein the one end is above the other end to a discharge position wherein the other end is above the one end;
a partition disposed in the vessel at said other end perpendicular to the longitudinal axis thereof and spaced from the liquid discharge outlet, wherein the partition is configured, when the vessel is in the normally operating position, to prevent passage of product to be peeled while allowing condensate to pass therethrough to form a condensate collection space thereunder such that the product to be peeled does not lie in the condensate during the application of steam;
steam supply and discharge means comprising an access opening in the vessel disposed above the product level when the vessel is in the normally operating position, a first steam line disposed colinearly with the horizontal tilting axis and a second line connecting the first line to the access opening; and
at least one stirring arm disposed above the partition and axially along the wall of the vessel and means for rotating same about the longitudinal axis of the vessel when the vessel is in the normally operating position.

### Claim 2 (depends on 1)

The steam peeling apparatus according to claim 1, wherein said at least one stirring arm or blade is mounted on said partition and the partition is mounted for rotatable movement therewith.

### Claim 3 (depends on 1)

The steam peeling apparatus according to claim 1, further comprising a plurality of angularly spaced stirring arms disposed axially along the vessel wall.

### Claim 4 (depends on 3)

The steam peeling apparatus according to claim 3, wherein said stirring arms are mounted on said partition and said partition is mounted for rotatable movement therewith.

### Claim 5 (depends on 1)

The steam peeling apparatus according to claim 1, wherein the partition comprises a grid.

### Claim 6 (depends on 5)

The steam peeling apparatus according to claim 5, wherein the grid is stationary with respect to the vessel.

### Claim 7 (depends on 6)

The steam peeling apparatus according to claim 6, wherein the grid permits passage of condensate only at the lower portion thereof when the vessel is in the normally operating position.

### Claim 8 (depends on 1)

The steam peeling apparatus according to claim 1, wherein the horizontal axis is outside and above the vessel.
