## Abstract

A system and its use for treatment of freight in a vacuum, having a chamber 1 for receiving a loaded container 9 having an external length CLa, an external width CBa and an external height CHa, wherein the chamber 1 has two side walls 11, 12 arranged opposite to a bottom 13 and top 14 and arranged opposite to a front wall 15 and back wall 16, and wherein a direction system XYZ is at right angles; and a conveying element 2 for parking and moving a container 9 relative to chamber 1 from a first position P1 outside the chamber 1 into a second position P2 inside the chamber 1; and a driving device 8 for moving between the first position P1 and the second position P2.

## Claims

### Claim 1

A system for treating freight in a vacuum, comprising:
a) a chamber, configured for providing a treatment in a vacuum and configured to receive a loaded freight container having an external length, an external width and an external height, wherein the chamber has
i) two side walls and
ii) a top arranged opposite a bottom as well as
iii) a back wall arranged opposite a front wall, and wherein the direction system XYZ is at right angles,
b) a conveying element, wherein the conveying element has a platform for putting down the freight container and a wheel or roller system for moving the platform together with the freight container relative to the chamber from the first position outside the chamber into the second position in the chamber, and
c) a driving device connected to the platform for moving the platform together with the freight container between the first position and the second position.

### Claim 2 (depends on 1)

The system according to claim 1, wherein there is provided directly connected to the chamber a module having a vacuum pump as well as a regulating and control system and pipes, with which a vacuum of up to 98% or a pressure of less than 100 mbar absolute can be produced in the chamber.

### Claim 3 (depends on 1)

The system according to claim 1, wherein a steam generator is additionally provided, with which saturated steam can be produced in a temperature range between 20° C. and 60° C. in the chamber.

### Claim 4 (depends on 1)

The system according to claim 1, wherein the chamber internally has a
a) length of at least 8.4 m (27 feet 6 inches),
b) width of at least 2.4 m (8′0″),
c) height of at least 2.5 m (8′6″) or
d) length of at least 6.0 m (19′10″),
e) width of a maximum of 2.6 m (8′7″),
f) height of at least 2.5 m (8′6″).

### Claim 5 (depends on 1)

The system according to claim 1, wherein the pitch for the freight container in the chamber is defined by the second position in the chamber, wherein in the X-direction in front of and/or behind the pitch at least one connecting sleeve for connecting at least one hose for conducting air and steam is provided on at least one side wall.

### Claim 6 (depends on 1)

The system according to claim 1, wherein the chamber has a front door and/or a rear door for loading and/or unloading the freight container.

### Claim 7 (depends on 1)

The system according to claim 1, wherein the platform has an angle of inclination α of at least 1.0°, at least in the second position.

### Claim 8 (depends on 7)

The system according to claim 7, wherein means are provided on the platform in order to raise the platform on one side at one end of the platform and/or to raise the freight container on one side at one end of the freight container or at both ends of the freight container.

### Claim 9 (depends on 1)

The system according to claim 1, wherein one access opening which can be locked with a door or with a flap is provided at least in one side wall in the chamber.

### Claim 10 (depends on 1)

The system according to claim 1, wherein the platform is longer by at least the dimension of the width of a door of the freight container than the length of the freight container and, as a result, has a working area for one person.

### Claim 11 (depends on 1)

The system according to claim 1, wherein a device for fixing doors of the freight container is arranged on the platform.

### Claim 12 (depends on 1)

The system according to claim 1, wherein an internal upper side of the bottom is at least partially inclined, and/or the bottom has channels, in such a manner that condensate can collect in at least one central location in the chamber.

### Claim 13 (depends on 1)

The system according to claim 1, wherein a suction device for extracting condensate and/or for catching solid parts is provided.

### Claim 14 (depends on 1)

A method for treating trunk wood, comprising the steps of using the system according to claim 1 to create vacuum and/or steam, wherein the wood is stored in the freight container with an external length of at least 8.4 m and the wood is positioned in the chamber together with the freight container.

### Claim 15 (depends on 1)

A method for treating trunk wood, wherein the trunk wood in a first step is stacked or stored the freight container with an external length of at least 8.4 m and in an indirectly or directly following further step is treated together with the freight container in a system for vacuum treatment according to claim 1.
